`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`I, Ingrid Hsieh-Yee, Ph.D., do hereby declare as follows:
`
`
`
`I have been retained as an independent expert witness on behalf of

`
`
`
`In forming the opinions expressed within this declaration, I have
`
`considered:
`
`(1) The documents listed above;
`
`3
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`(2) The reference materials cited herein; and
`
`(3) My own academic background and professional experiences, as
`
`described below.
`
` My complete qualifications and professional experience are
`
`described in my curriculum vitae, a copy of which is provided as Appendix A.
`
`The following is a brief summary of my relevant qualifications and professional
`
`experience.
`
`
`
`I am currently a Professor in the Department of Library and
`
`Information Science at the Catholic University of America. I have experience
`
`working in an academic library, a medical library, and a legislative library and
`
`have been a professor for more than 25 years. I hold a Ph.D. in Library and
`
`Information Studies from the University of Wisconsin-Madison and a Masters in
`
`Library and Information Studies from the University of Wisconsin-Madison.
`
`
`
`I am an expert on library cataloging and classification and have
`
`published two books on this subject, Organizing Audiovisual and Electronic
`
`Resources for Access: A Cataloging Guide (2000, 2006). My specialization is
`
`information organization and access and I have taught a variety of courses on
`
`how to organize information to facilitate access to and usage of information
`
`resources, including “Cataloging and Classification,” “Internet Searches and Web
`
`Design,” “Advanced Cataloging and Classification,” “Organization of Internet
`
`4
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`Resources,” “Advanced Information Retrieval and Analysis Strategies,”
`
`“Information Literacy
`
`Instruction,” and “Digital Content Creation and
`
`Management.” My research interests cover cataloging and classification, Web
`
`search behavior, information organization, metadata, information retrieval,
`
`information architecture, digital collections, scholarly communication, user
`
`interaction with information systems, and others.
`
`
`
`I am fully familiar with library cataloging standards and practices. I
`
`am also familiar with common practices in creating digital contents, and indexing
`
`information resources to ensure user access to the content, especially digital
`
`scholarly materials. In my courses I cover various information systems, such as
`
`library catalogs, union catalogs, proprietary databases, open access databases,
`
`institutional repositories, subject repositories, and portals on the Web; and help
`
`students develop strategies to find and access information resources in these
`
`systems and on the open Web. I am familiar with trends in scholarly
`
`communication, cover these trends in my teaching, and conducted research in this
`
`area.

`
`(2002). Audio over Bluetooth and MOST. (“Ekström”), Master Thesis, Dept. of
`
`Science and Technology, Linköping University. When I was originally asked to
`
`5
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`prepare this declaration, I searched Google for “Audio over Bluetooth and
`
`MOST” and the search results led me to the Ekström record (Exhibit-2) on the
`
`DiVA site, and the link on the record led me to the fulltext of this thesis. I
`
`personally searched for this title, obtained the Ekström record (Exhibit-2), and
`
`downloaded the thesis from the link on the record.
`
` DiVA (Digitala Vetenskapliga Arkivet) is and was a publication
`
`database at Linköping University (LiU) available online through any Internet
`
`browser on any computer connected to the Internet. It is also a digital portal that
`
`serves as a “finding tool and an institutional repository for research publications
`
`and student theses written at 47 universities and research institutions”
`
`(http://www.diva-portal.org/smash/search.jsf?dswid=-2310).
`
` As a digital archive, it is designed to ensure long-term access and
`
`preservation of research publications and student theses with the intent to
`
`“effectively spread LiU’s research, make the researchers and the students
`
`publications visible and available, offer a collective tool for the university’s
`
`publications, use for annual reports, statistics and quantitative studies of scientific
`
`material, bibliometrics, secure the access of LiU’s publications, show the general
`
`public how LiU’s
`
`resources are used”
`
`(see “What
`
`is DiVA?” at
`
`http://www.ep.liu.se/authorinf/diva.en.asp). “Open access” has the benefits of
`
`increasing the visibility and impact of research, reducing access barriers to
`
`6
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`research, putting “rich and poor on equal footing” for access to research, and
`
`enabling universities to raise their profiles and carry out their mission to share
`
`knowledge (Suber 2004, Appendix D). The creation and maintenance of DiVA
`
`reflect LiU’s commitment to open access. LiU “Rector’s Policy on Electronic
`
`Publishing” (Appendix B) makes it clear that “As a result of the decision of the
`
`University’s Board of Directors in April 1996, the electronic publisher,
`
`Linkö ping University Electronic Press (LiU E-Press), was created as a unit within
`
`the University, connected with the University Library… It is very important for
`
`the University that the academic production of the employees and students be
`
`spread as widely and effectively as possibly, so that other researchers and the
`
`general public can obtain this material as easily as possible. For the University,
`
`the publication of this material is of highest importance for the creation of the
`
`University’s profile and hence for the picture of the University as seen by the rest
`
`of the world. The objective is that all research results (including theses) and all
`
`more qualified work produced by undergraduate students be published at LiU E-
`
`Press (as well as in other forms such as scientific journals).”
`
` The “Policy for Electronic Publishing at Linkö ping University
`
`Electronic Press” (Appendix C) identifies “student theses” among the types of
`
`scientific publications that are published by the LiU E-Press and provides
`
`guidelines for authors. The LiU library site provides “Register & Published in
`
`7
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`DiVA” (http://www.ep.liu.se/authorinf/index.en.asp) to inform researchers and
`
`students on how to contribute to DiVA, and “Publish student theses in DiVA”
`
`(http://www.ep.liu.se/exjobb/index.en.asp) includes a document template and a
`
`template of “library information sheet” (http://www.ep.liu.se/helpfiles/doc/
`
`bbladmalleng.rtf) to assist students in creating records for DiVA.
`
` A person using the DiVA Portal would have been able to search the
`
`publication database through an online interface that allows the user to search for
`
`the
`
`relevant
`
`topic
`
`using
`
`keywords
`
`(http://www.diva-
`
`portal.org/smash/search.jsf?dswid=-2310) in any of three modes of searching:
`
`Simple search, Advanced search – Research publications, and Advanced search –
`
`Student theses.
`
`Exhibit-2 and Exhibit-3
`
` Exhibit-2 is the DiVA record for “Ekström” that I accessed on Jan.
`
`16, 2018. The record contains data in Swedish and English. It identifies the
`
`authors as “Ekström, Peter” and “Hoel, Fredrik” of the “Department of Science
`
`and Technology” of the Linköping University, and the title as “Audio over
`
`Bluetooth and MOST”. It shows the publication is a “student thesis” that is 67
`
`pages
`
`long and published
`
`in “2002” by “Institutionen för
`
`teknik och
`
`naturvetenskap”. The record includes an abstract, keywords, a subject category
`
`“Engineering and Technology” and a few identifiers, such as ISRN (International
`
`8
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`Standard Report Number) and “URN” that provides a permanent link to the
`
`Ekström record. The record also shows “2002-05-23” as “created” date and
`
`“2002-05-23” as “Available from” date. In most institutional repositories records
`
`are date stamped by computers when they are added to the repositories. My
`
`communication with the editor of DiVA confirms this as the practice of DiVA
`
`and that the Ekström record was created on “2002-05-23” (i.e., May 23, 2002)
`
`and became available for public access on “2002-05-23” (i.e., May 23, 2002).
`
`The record contains a link to the fulltext of this thesis on the LiU DiVA system at
`
`http://liu.diva-portal.org/smash/get/diva2:18370/FULLTEXT01.pdf.
`
` The Ekström record on DiVA, the digital portal, includes a link to
`
`“About DiVA Portal” (http://www.diva-portal.org/smash/aboutdiva.jsf?dswid=-
`
`2342) that indicates “the research publications and student theses found in DiVA
`
`portal have been published and registered at the university or college of origin.
`
`There is bibliographic information in the database for every title and usually an
`
`abstract and a link to the full text at the university or college where it was
`
`published.” I accessed LiU’s Library Catalog at (http://www.bibl.liu.se/?l=en) to
`
`determine if a record for this thesis is in the library system. From the library
`
`catalog search screen I selected “Research and theses from LiU” and searched by
`
`“keyword” for “bluetooth MOST”. The search result shows that the LiU Ekström
`
`9
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`record (Exhibit-3) includes information identical to the DiVA Ekström record
`
`(Exhibit-2).
`
`
`
`I have also been provided with the Affidavit of Christopher Butler
`
`(Ex. 1011) with records from the Internet Archives related to Ekström. I have
`
`used Internet Archive in the past and am familiar with Internet Archives’ practice
`
`of assigning a URL to an archived file reflecting the point of time a URL was
`
`captured. Page 3 of the records attached to Ex. 1011 confirms that the LiU
`
`Electronic
`
`Press
`
`site
`
`provided
`
`“Publicera
`
`exjobb/Publish Thesis”
`
`(http://www.ep.liu.se/exjobb/index.en.asp), which was “Last modified 2002-05-
`
`07 16:13 by webmaster@ep.liu.se” and archived by Internet Archive on
`
`“20021016175228” (i.e., October 16, 2002 at 5:52 p.m. and 28 seconds). This
`
`web page showed that the system allowed a user to search for a topic using
`
`keywords. Page 7 of these records has a heading of “Examensarbeten,
`
`Kommunikatons- och transportsystem, 2002” (Degree Projects, Communication
`
`and Transport Systems, 2002) and lists the number, author, title, and ISRN
`
`(International Standard Report Number) of papers and theses published in 2002.
`
`Number “021” is the thesis by Peter Ekström and Fredrik Hoel. This list on p. 7
`
`was “Last modified 2002-08-16 09:12 by webmaster@ep.liu.se” and archived by
`
`the Internet Archive on “20020818142227” (i.e., August 18, 2002 at 2:22 p.m.
`
`and 27 seconds). Pages 8 and 9 of these records show the thesis information sheet
`
`10
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of
`Petition for Inter Partes Review of USP 8,155,342
`that indicates the title, series number, defense date, language, institute, abstract,
`
`and keywords of this publication. It also includes a link to the PDF version of the
`
`thesis. These pages were
`
`“Last modified 2002-05-23 13:49 by
`
`webmaster@ep.liu.se” and archived by Internet Archive on “20020824115811”
`
`(i.e., August 24, 2002 at 11:58 a.m. and 11 seconds). The information on these
`
`two pages is identical to the DiVA Ekström record (Exhibit-2) and LiU Ekström
`
`record (Exhibit-3). Page 10 lists the Internet Archive URL for the thesis by Peter
`
`Ekström and Fredrik Hoel with an archived date of “20030802005803” (i.e.,
`
`August 2, 2003 at 00:58 a.m. and 3 seconds). Pages 11 to 77 is the archived
`
`version of the thesis and it is identical to Exhibit-1.
`
` Taken together, the full text of “Ekström”, the DiVA Ekström
`
`record, the LiU Ekström record, the Internet Archive records, and the dates of
`
`record creation and public availability on the DiVA record inform my opinion
`
`that LiU uses DiVA to make research publications and student theses as widely
`
`known as possible so that other researchers and the public can obtain LiU’s
`
`research publications and student theses as easily as possible. The DiVA Ekström
`
`record and the LiU Ekström record, created on May 23, 2002 and became
`
`available on that date, makes it possible for the public and any interested
`
`researchers to discover and access this thesis at the DiVA Portal and at the LiU
`
`Library Catalog starting May 23, 2002. Internet Archive records inform me the
`
`11
`
`
`

`

`Declaration of Dr. Ingrid Hsieh-Yee In Support Of

`web page listing this thesis was archived by the Internet Archive on August 18,

`
`August 24, 2002, and the thesis itself was archived by the Internet Archive on
`
`August 2, 2003.
`
`CONCLUSION
`
`In signing this declaration, I recognize that the declaration will be
`
`filed as evidence in a contested case before the Patent Trial and Appeal Board of
`
`the United States Patent and Trademark Office. I also recognize that I may be
`
`subject to cross-examination in the case. If cross-examination is required of me, I
`
`will appear.

`Abstract
`
`In this Master Thesis the possibility of connecting standard products wirelessly to
`MOST, a multimedia network for vehicles, are investigated. The wireless technique
`analysed is Bluetooth. The report theoretically describes how Bluetooth could be
`integrated with MOST via a gateway. Future scenarios that are made possible by this
`gateway are also described. The solution presents how a connection could be
`established and how the synchronous audio is transferred from a Bluetooth sound
`source to the MOST network.
`
`As a sound source equipment supporting the Bluetooth Headset Profile is used. It
`communicates with the MOST network via a gateway. As the recipient of the system,
`a speaker module connected to MOST is used.
`
`The gateway task when transmitting audio, using synchronous data, is to convert the
`sample rate of the audio stream from 8 kHz used in the Bluetooth system to 48 kHz
`used in MOST. This is done by interpolation and filtering. Several different methods
`for this are described and compared.
`
`The key issue in this report is the sample rate conversion between the two systems
`sample frequencies.

`Sammanfattning
`
`I detta examensarbete studeras möjligheten att ansluta standardprodukter trådlöst till
`MOST, ett multimedianätverk för fordon. Den trådlösa tekniken som analyseras är
`Bluetooth. Rapporten beskriver teoretiskt hur Bluetooth ska integreras med MOST via
`en gateway och tar även upp olika framtida scenarier som möjliggörs med hjälp av
`denna gateway. Lösningen beskriver hur en förbindelse kan upprättas och ljuddata
`överföras från en ljudkälla till MOST-nätet med hjälp av Bluetooth-teknik.
`
`Som ljudkälla används utrustning som stöder ’Bluetooth Headset Profile’. Den
`kommunicerar via en gateway med MOST-nätet. Som mottagare i systemet finns en
`högtalarmodul ansluten till MOST.
`
`form av synkron data, är gatewayens uppgift att
`i
`Vid överföring av ljud,
`samplingskonvertera ljudströmmen från 8 kHz som används i Bluetooth-delen till 48
`kHz som används på MOST. Detta sker med interpolation och filtrering. Flera olika
`metoder för detta redovisas och jämförs.
`
`Huvuduppgiften i rapporten är samplingskonverteringen mellan de olika systemens
`samplingsfrekvenser.

`1 Introduction
`
`The aim of this Thesis is to design a gateway between Bluetooth and MOST, Media
`Oriented Systems Transport. The gateway shall be able to handle control data to
`initiate a synchronous link and to route synchronous audio sent from Bluetooth to
`MOST.
`
`1.1 Background
`MOST is already an established technology in the automotive industry and Bluetooth
`is becoming more and more interesting. Combining those techniques would bring the
`possibilities further to another level where the applications in the vehicle can connect
`wirelessly. As a step in this evolution Volvo Technological Development is interested
`in developing competence in this area.
`
`1.2 Method
`The method used throughout this Master Thesis has been an iterative process. The
`first thing done was a target plan. It contained the different goals, a time plan etc.
`Then a literature study was made in which the Bluetooth and MOST technologies
`were studied. Previous reports in the area of Bluetooth, performed at Volvo
`Technological Development, were read [20, 21]. The task was separated into smaller
`tasks where the solut
