`
`DENIAL OF REQUEST FOR POWEROF ATTORNEY
`
`The request for Powerof Attorneyfiled 06/17/2016 is acknowledged. However, the request cannot be
`granted atthis time for the reason stated below.
`
`LJ The Powerof Attorney you provided did not comply with the new Powerof Attorney rules that became
`effective on June 25, 2004. See 37 CFR 1.32.
`
`L} The revocationis not signed by the applicant, the assignee of the entire interest, or one particular
`principal attorney having the authority to revoke.
`
`CL) The Powerof Attorney is from an assignee and the Certificate required by 37 CFR 3.73(c) has not been
`received.
`
`CL) The person signing for the assignee has omitted their empowermentto sign on behalf of the assignee.
`
`LJ The inventor(s) is without authority to appoint attorneys since the assignee has intervened as provided
`by 37 CFR 3.71.
`
`, aco-inventorin this application, has been omitted.
`C) The signature(s) of
`The Powerof Attorney will be entered upon receipt of confirmation signed by said co-inventor(s).
`
`C) The person(s) appointed in the Powerof Attorney is not registered to practice before the U.S. Patent and
`Trademark Office.
`
`) Only one Customer Numbercan be designated for the Powerof Attorney in an application. The
`Customer Numberthat was capturedis the first Customer Numberprovided on the Powerof Attorney
`document.
`
`OA request under 37 CFR 1.48 to add an inventor was grantedin this application, however, no powerof
`attorney consistent with the powerof attorney granted by the originally named inventive entity has been
`received. Thus, the addition of the inventor has resulted in the loss of powerof attorneyin the
`application. See 37 CFR 1.32(e).

`Multifunctional Charger System and Method
`
`CROSS-REFERENCE TO RELATED APPLICATION
`
`This application is related to the following prior application: System and
`
`5 Method for Adapting a USB to Provide Power for Charging a Mobile Device,
`
`United States Provisional Application No. 60/273021, filed March 1°, 2001. This
`
`prior application, including the entire written description and drawing figures, is
`
`hereby incorporated into the present application by reference.
`
`10
`
`BACKGROUND
`
`1.
`
`FIELD OF THE INVENTION
`
`This invention relates generally to power adapters and battery chargers.
`
`More particularly, the invention provides a USB (Universal Serial Bus) power
`
`
`
`adapter and battery charger for chargingafirst battery at a mobile device and a
`
`15.
`
`second battery at the charger simultaneously or independently. The invention is
`
`particularly well
`
`suited for use
`
`in Personal Digital Assistants, mobile
`
`communication devices,
`
`cellular phones,
`
`and wireless
`
`two-way e-mail
`
`communication devices, which may have a USBinterface (collectively referred to
`
`herein as "mobile devices"). The invention provides utility, however,
`
`in any
`
`20
`
`device that may need to draw power via the USB interface and/or has a
`
`rechargeable battery.

`
`DESCRIPTION OF THE RELATED ART
`
`Supplying powerto a mobile device involves the participation of a mobile
`
`device on one hand,as well as the participation of a powersourceon the other.
`
`5
`
`On one hand, most mobile devices provide a first power interface for
`
`receiving power from a power source, for instance to recharge a battery, and a
`
`second data interface for communicating that is separate from the powerinterface.
`
`Although it is desirable to have a combined power and data interface, most
`
`combined interfaces are non-standard so that one mobile device provided by one
`
`10 manufacturer with one combined interface cannot cooperate with the combined
`
`interfaces of other manufacturers.
`
`Furthermore, many mobile devices now have USB (Universal Serial Bus)
`
`interfaces for communicating, although they still maintain a separate power
`
`interface, such as a barrel connector, for receiving power.
`
`15
`
`However, a USB chargeable mobile device provided according to System
`
`and Method for Adapting a USB to Provide Power for Charging a Mobile Device,
`
`United States Provisional Application No. 60/273021, filed March 1*, 2001, has a
`
`single USB interface for both communicating and recharging a battery. Given that
`
`USB connectors are popular widely supported in industry, a USB chargeable
`
`20
`
`device solves the problem of the combined interface at a USB chargeable mobile
`
`device.

`Page 12 of 38
`
`

`

`On the other hand, traditional USB power source devices, such as hubs
`
`and hosts, require that a USB device participate in a host-initiated process called
`
`enumeration in order to be compliant with the current USB specification in
`
`drawing power from the USB interface. Although a USB chargeable device 1S
`
`5
`
`capable of enumeration,it is preferable in somesituations, such as when a host is
`
` 10
`
`
`kek
`
`not available, as often happens during normal use of a mobile device, to be able to
`
`adapt alternate power sources such as conventional AC outlets and DC car
`
`sockets, to supply power to a USB device via a USB interface.
`
`There is a need for a USB poweradapter that can provide power to a USB
`
`device without necessarily requiring that
`
`the USB device participate in
`
`enumeration before drawing 5 unit loads of power over a USBinterface.
`
`Furthermore, there is a need for a method that can allow a USB device to
`
`differentiate between the provided USB power adapter andtraditional USB power
`
`sources such as hosts and hubs.
`

`
`DETAILED DESCRIPTION
`
`Fig. 1 is a block diagram of a USB chargeable mobile device 10 with
`
`15
`
`whichtheinstant invention may cooperate. The mobile communication device 10
`
`is preferably a two-way communication device having at least voice or data
`
`communication capabilities. The device preferably has
`
`the capability to
`
`communicate with other computer systems on the Internet. Depending on the
`
`functionality provided by the device, the device may be referred to as a data
`
`20 messaging device, a two-way pager, a cellular telephone with data messaging

`

`
`
`
`capabilities, a wireless Internet appliance or a data communication device (with or
`
`without telephony capabilities).
`
`Where the device 10 is enabled for two-way communications, the device
`
`will
`
`incorporate a communication subsystem 11,
`
`including a receiver 12, a
`
`5
`
`transmitter 14, and associated components such as one or more, preferably
`
`embeddedor internal, antenna elements 16 and 18, local oscillators (LOs) 13, and
`
`a processing module such as a digital signal processor (DSP) 20. As will be
`
`apparent to those skilled in the field of communications, the particular design of
`
`the communication subsystem 11 will be dependent upon the communication
`
`10
`
`network in which the device is intended to operate. For example, a device 10
`
`destined for a North American market may include a communication subsystem
`
`11 designed to operate within the Mobitex™ mobile communication system or
`
`DataTAC™ mobile communication system, whereas a device 10 intended for use
`
`in Europe may incorporate
`
`a General Packet Radio Service
`
`(GPRS)
`
`15
`
`communication subsystem 11.
`
`Network access requirements will also vary depending upon the type of
`
`network 19. For example, in the Mobitex and DataTAC networks, mobile devices
`
`such as 10 are registered on the network using a unique personal identification
`
`numberor PIN associated with each device. In GPRS networks however, network
`
`20
`
`access is associated with a subscriber or user of a device 10. A GPRS device
`
`therefore requires a subscriber identity module (not shown), commonly referred to

`
`

`

`
`
`
`
`as a SIM card, in order to operate on a GPRS network. Without a SIM card, a
`
`GPRS device will not be fully functional. Local or non-network communication
`
`functions (if any) may be operable, but the device 10 will be unable to carry out
`
`any functions involving communications over network 19. When required
`
`5
`
`networkregistration or activation procedures have been completed, a device 10
`
`may send and receive communication signals over the network 19. Signals
`
`received by the antenna 16 through a communication network 19 are input to the
`
`receiver 12, which may perform such common receiver functions as signal
`
`amplification, frequency down conversion,filtering, channel selection and the
`
`10
`
`like, and in the example system shown in Fig. 1, analog to digital conversion.
`
`Analog to digital conversion of a received signal allows more complex
`
`communication functions such as demodulation and decoding to be performed in
`
`the DSP 20. In a similar manner, signals to be transmitted are processed,
`
`including modulation and encoding for example, by the DSP 20 and input to the
`
`15
`
`transmitter 14 for digital to analog conversion, frequency up conversion,filtering,
`
`amplification and transmission over the communication network 19 via the
`
`antenna 18.
`
`The DSP 20 not only processes communication signals, but also provides
`
`for
`
`receiver and transmitter control. For example,
`
`the gains applied to
`
`20
`
`communication signals in the receiver 12 and transmitter 14 may be adaptively
`
`controlled through automatic gain control algorithms implemented in the DSP 20.

`

`
`
`The device 10 preferably includes a microprocessor 38 which controls the
`
`overall operation of the device. Communication functions, including at least data
`
`and voice communications, are performed through the communication subsystem
`
`11. The microprocessor 38 also interacts with further device subsystems such as
`
`5
`
`the display 22, flash memory 24, random access memory (RAM) 26, auxiliary
`
`input/output
`
`(I/O) subsystems 28, USB port 30, keyboard 32, speaker 34,
`
`microphone36, a short-range communications subsystem 40 and any other device
`
`subsystems generally designated as 42. Of particular interest
`
`is charging
`
`subsystem 44, which is connected to power source 46 and battery 48. Charging
`
`10
`
`subsystem 44 provides power to device 10, preferably from battery 48. However,
`whenbattery 48 becomes depleted, power source 46 is used to charge battery 48,
`
`and optionally power device 10. Power source 46 preferably obtains power from
`
`USBport 30.
`
`Someof the subsystems shown in Fig. 1 perform communication-related
`
`15
`
`functions, whereas other subsystems may provide “resident” or on-device
`
`functions. Notably, some subsystems, such as keyboard 32 and display 22 for
`
`example, may be used for both communication-related functions, such as entering
`
`a text message for transmission over a communication network, and device-
`
`resident functions such as a calculatorortasklist.
`
`20
`
`Operating system software used by the microprocessor 38 is preferably
`
`stored in a persistent store such as flash memory 24, which mayinstead be a read

`

`
`
`
`only memory (ROM)orsimilar storage element (not shown). Those skilled in the
`
`art will appreciate that the operating system, specific device applications, or parts
`
`thereof, may be temporarily loadedinto a volatile store such as RAM 26. It is
`
`contemplated that received communication signals may also be stored to RAM
`
`5
`
`26.
`
`The microprocessor 38,
`
`in addition to its operating system functions,
`
`preferably enables execution of
`
`software applications on the device. A
`
`predetermined set of applications which control basic device operations, including
`
`at least data and voice communication applications for example, will normally be
`
`10
`
`installed on the device 10 during manufacture. A preferred application that may
`
`be loaded onto the device may be a personal
`
`information manager (PIM)
`
`application having the ability to organize and manage data items relating to the
`
`device user such as, but not limited to e-mail, calendar events, voice mails,
`
`appointments, and task items. Naturally, one or more memory stores would be
`
`15
`
`available on the deviceto facilitate storage of PIM data items on the device. Such
`
`PIM application would preferably have the ability to send and receive data items,
`
`via the wireless network. In a preferred embodiment, the PIM data items are
`
`seamlessly integrated, synchronized and updated, via the wireless network, with
`
`the device user’s corresponding data items stored or associated with a host
`
`20
`
`computer system thereby creating a mirrored host computer on the mobile device
`
`with respect to the data items at least. This would be especially advantageous in

`

`

`
`
`
`
`the case where the host computer system is the mobile device user’s office
`
`computer system. Further applications may also be loaded onto the device 10
`
`through the network 19, an auxiliary I/O subsystem 28,serial port 30, short-range
`
`communications subsystem 40 or any other suitable subsystem 42, and installed
`
`5
`
`by a user in the RAM 26 or preferably a non-volatile store (not shown) for
`
`execution by the microprocessor 38. Such flexibility in application installation
`
`increases the functionality of the device and may provide enhanced on-device
`
`functions, communication-related functions, or both. For example,
`
`secure
`
`communication applications may enable electronic commerce functions and other
`
`10
`
`such financial transactions to be performed using the device 10.
`
`In a data communication mode,a received signal such as a text message or
`
`web page download will be processed by the communication subsystem 11 and
`
`input to the microprocessor 38, which will preferably further process the received
`
`signal for output to the display 22, or alternatively to an auxiliary /O device 28.
`
`15
`
`A user of device 10 may also compose data items such as email messages for
`
`example, using the keyboard 32, which is preferably a complete alphanumeric
`
`keyboard or telephone-type keypad,
`
`in conjunction with the display 22 and
`
`possibly an auxiliary I/O device 28. Such composed items may then be
`
`transmitted over a communication network through the communication subsystem
`
`20
`
`Ii.

`
`
`
`For voice communications, overall operation of
`
`the device
`
`10 is
`
`substantially similar, except that received signals would preferably be output to a
`
`speaker 34 and a microphone 36 would generate signals for transmission.
`
`Alternative voice or audio I/O subsystems such as a voice message recording
`
`5
`
`subsystem may also be implemented on the device 10. Although voice or audio
`
`signal output is preferably accomplis
