`1, Paul James Mahoney, declare as follows:
`
`1.
`
`I am over the age of 21 years and am fully competent to make this
`
`Declaration. I make the following statements based on personal knowledge and, if
`
`called to testify to them, could and would do so.
`
`2.
`
`I received my Bachelor’s of Science in Electrical Engineering from the
`
`University of Dayton in Dayton, Ohio in 1966.
`
`I also received a Masters in
`
`Biomedical Engineering from Southern Methodist University in Dallas, Texas in
`
`1972.
`
`3.
`
`l was employed at Select Comfort Corporation, which is now known as
`
`Sleep Number Corporation (referred to herein as “Sleep Number”), as an engineer
`
`and later as Senior Product Design Engineer from June 1995 to July 201 1. Prior to
`
`joining Sleep Number, I was the Director of Research and Development at Aequitron
`
`Medical.
`
`1 also worked as the Manager of Corporate Research Laboratories at 3M.
`
`4.
`
`5.
`
`A copy of my current CV is attached as Appendix A.
`
`While at Sleep Number, I was heavily involved in the product research,
`
`development, and design of air control systems sold as part of the company’s
`
`adjustable air mattress systems. Sleep Number refers to those systems as their
`
`proprietary Sleep Number® beds. As part of my job, we did extensive testing on
`
`different designs. We regularly used test subjects to try out new concepts or designs.

`

`We also regularly received relevant customer feedback, which would inform our
`
`design choices and strategies.
`
`6.
`
`I was an inventor in the field of adjustable mattresses.
`
`I am the named
`
`inventor of several United States patents, including U.S. Patent No. 5,904,172 (“the
`
`‘172 Patent”), U.S. Patent No. 9,737,154 (“the ‘154 Patent”), and U.S. Patent No.
`
`8,769,747 (“the ‘747 Patent”). Each of these patents is in the field of adjustable air
`
`beds.
`
`7.
`
`The ‘172 Patent teaches a novel system for adjustable air beds that
`
`allows for continuous monitoring and adjusting of the pressure in an air bladder
`
`within a mattress in order to adjust the firmness for a desired user. Specifically,
`
`pressure is monitored from a valve enclosure assembly, which is remotely located
`
`from the
`
`air bladder.
`
`The pressure
`
`is monitored before
`
`and during
`
`inflation/deflation, allowing the system to inflate/deflate the air bladder until the
`
`pressure sensed within an air chamber
`
`in the valve enclosure assembly is
`
`substantially equal to the desired pressure, at which point inflation/deflation stops.
`
`8.
`
`The purpose behind adjustable air beds, and the reason Sleep Number
`
`believed consumers would purchase its adjustable air beds,
`
`is that users can
`
`individualize or customize the mattress, as they desire,
`
`to his/her preferred
`
`firmness—22a, they can change the firmness at any time. As such, each user may

`
`

`

`make a selection of his/her desired pressure, which I refer to as the desired pressure
`
`setpoint.
`
`9.
`
`The degree or magnitude of pressure adjustments in an adjustable air
`
`bed are very small. As an initial matter, the air bladders in the adjustable beds
`
`usually have a fully deflated pressure of 0.0 or 0.05 PSI and a fully inflated pressure
`
`of around 0.6 PS1. While other ranges are possible, those skilled in the art of
`
`adjustable air mattresses would appreciate that each pressure adjustment would be a
`
`fraction of a fraction of a PSI. For example, Sleep Number beds have sleep settings
`
`or desired pressure setpoints that range from 0 to 100 in increments of 5 (i.e. 0, 5,
`
`10, 15, etc.). Accordingly, a sleep setting of 0 is indicative of a fully deflated air
`
`bladder, i. e. 0.0 or 0.05 PS1, and a sleep setting of 100 is indicative of a fully inflated
`
`air bladder, i.e., 0.6 PSI.
`
`10. We did several experiments at Sleep Number and we found that users
`
`can generally appreciate the difference in firmness between pressure changes of as
`
`little as 0.01 to 0.03 PSI.
`
`For example, we found that users could generally
`
`appreciate the difference in firmness between a sleep setting of 30 (approx. 0.18 PSI)
`
`and 35 (approx. 0.21 PSI).
`
`In fact, most users could tell a huge difference between
`
`each sleep setting when in the 20-40 (approx. 0.12 to 0.24 PSI) sleep setting range.
`
`However, due to the pressure transducers available to us it was difficult
`
`to
`
`consistently achieve a sleep setting with increments smaller than 0.03 PSI.
`
`In
`
`Sleep Number Corp.

`
`

`

`addition, as the pressure increased, e.g., when approaching sleep settings of 80
`
`(approx. 0.48 PSI), users could not always appreciate the difference between
`
`pressure adjustments smaller than 0.03 PSI. Accordingly, while different increments
`
`may be used, we consistently used pressure adjustments in increments of 0.03 PSI.
`
`11.
`
`Through my experience in the bed industry, I understood that most
`
`individuals had a predisposition to a certain firmness, e.g., sofi, medium, or firm.
`
`Indeed, in my experience most users or test subjects preferred a firmness within the
`
`20-40 sleep setting range, or 0.12 to 0.24 PS1.
`
`It is my opinion, through my work
`
`and experiences, that users often toggle between desired pressures that are very close
`
`to one another.
`
`In other words, a user preferring a soft to medium firmness may
`
`change from a Sleep Number setting of 30 to 35 (or vice versa), which as discussed
`
`above represents a very small change of .03 PSI but would be a noticeable change
`
`in firmness for the user. While a user could drastically change the firmness of his/her
`
`mattress by switching between a sleep setting of 20 (approx. 0.12 PSI) and 80
`
`(approx. 0.48 PSI),
`
`this magnitude of change was considered to be more the
`
`exception than the rule. That is, the understanding of those working in the field was
`
`that users who were predisposed to a generally firm mattress would not often switch
`
`to a very soft setting (or vice versa). Additionally, even if a user changed from a
`
`setting of 0 to 100 (or vice versa), it would only represent an approximate change of
`
`0.6 PS1.

`

`12. We also learned that users of adjustable air beds would find a preferred
`
`or favorite sleep setting and, if the pressure of the bed was ever changed for any
`
`reason, the user wanted to be able to return to his/her preferred setting with accuracy.
`
`For example, if a user whose preferred sleep setting was 30 (approx. 0.18 PSI) was
`
`using an adjustable air mattress system with a sleep setting set at 50 (approx. 0.3),
`
`the user wanted to be able to select a sleep setting of 30 and know that the pressure
`
`would be accurately adjusted down to approx. 0.18 PSI. Because of this consistency
`
`of accurately achieving a particular pressure, a user could also be confident of
`
`achieving a similar sleep on a different Sleep Number bed, for example while
`
`traveling. Accurately achieving this pressure was especially important because, as I
`
`described above, most users could appreciate a huge difference in pressures in the
`
`most common sleep setting range of 20—40.
`
`13.
`
`The purpose of an adjustable air mattress system is to allow a user to
`
`be able to easily adjust the firmness of his/her side of their bed to a desired pressure
`
`setting, which may be different than the other side of the bed. Older systems, usually
`
`those using blower pumps, were designed to simply allow a user to inflate or deflate
`
`the air bladder within the mattress. These older systems did not include a preselected
`
`pressure setting but simply allowed a user to inflate or deflate for a period of time.
`
`With the introduction of preselected pressure settings, a user could select a setting
`
`that would correspond to a particular pressure. However, these systems did not have

`

`a way to accurately and continuously monitor the pressure during inflation or
`
`deflation, and therefore consistently overshot or undershot the pressure, which
`
`resulted in either ( 1) a pressure adjustment that did not accurately and consistently
`
`achieve the user’s desired pressure or (2) a problem of multiple iterative adjustments
`
`while attempting to achieve the desired pressure, which We called hunting or
`
`pecking. Through the development of the innovative technologies disclosed in the
`
`‘172, ‘154, and ‘747 Patents and described herein, we were able to solve these
`
`problems. With these technologies, after a user selects a setting and the desired
`
`pressure is calculated, the pressure may be consistently adjusted, either by inflation
`
`or deflation, until the actual pressure is substantially equal to the desired pressure.
`
`14. While inventing the technology disclosed in the ‘ 172 Patent, we wanted
`
`to create a system that could achieve the desired pressure setpoint while reducing
`
`costs, noise, and heat, the latter of which was generated by solenoids periodically
`
`opening and closing while hunting for the correct pressure.
`
`Jim Gifft, the other
`
`inventor of the ‘ 172 Patent, and I designed an improved valve enclosure assembly
`
`so that the pressure in the air bladder could be continuously monitored from the valve
`
`enclosure, allowing the system to stop inflation/deflation when the sensed pressure
`
`was substantially equal to the desired setpoint.
`
`15.
`
`This desire, to achieve a precise and accurate pressure adjustment so
`
`that the user would be able to achieve a setting substantially close to what he/she

`

`selected, became even more paramount while inventing the technology disclosed in
`
`the ‘747 and ‘ 154 Patents. Accordingly, I was part of a team that designed a method
`
`or system for an adjustable bed that would more accurately achieve the desired
`
`inflation/deflation for each user.
`
`16.
`
`Generally in the adjustable air bed industry, and specifically in
`
`developing the technologies disclosed in the ‘172,
`
`‘747, and ‘ 154 Patents,
`
`the
`
`accuracy of the pressure adjustment was more important than limiting the time spent
`
`achieving the desired pressure point.
`
`In other words, it was understood by those in
`
`the industry that it would be better to spend more time adjusting the pressure if you
`
`could ensure a more accurate adjustment. Indeed, it was our understanding that users
`
`consider precision or accuracy in adjustments to be of paramount
`
`importance
`
`because that allows users to achieve a desired firmness setting. Because, as I
`
`mentioned above, it was our understanding that users could appreciate the difference
`
`between even 0.03 PSI or less, it was important to achieve a pressure as close to the
`
`desired pressure as possible.
`
`I do not believe the user experience would have been
`
`positive or successful if the adjustable air mattress system did not achieve a precise
`
`and accurate pressure adjustment.
`
`17.
`
`The ‘ 172 Patent allows consumers to easily adjust the firmness of
`
`his/her side of their bed to a desired pressure setting.
`
`I believe incorporating this
`
`technology was beneficial to, and desired by, consumers.
`
`In fact, when we first

`

`invented a new air controller incorporating this technology (which we called the
`
`Stealth pump), no one at
`
`the company believed that we could develop an air
`
`controller with the high degree of efficiency and that was so quiet. To get people on
`
`board, I snuck a Stealth pump into a meeting and let it run during the duration. At
`
`the end, when I revealed that the air controller had been running the entire meeting,
`
`my colleagues believed that it was worthwhile to invest in developing the Stealth
`
`pump. After doing so, we believed as a company that this technology was so
`
`important that Sleep Number began incorporating the ‘ 172 Patent technology into
`
`more and more of Sleep Number’s air controllers over time.
`
`18. When the ‘172 Patent technology was first incorporated into a Sleep
`
`Number air controller for sale in 1998 (the UFCS3 pump), there was only one
`
`mattress model (the Ultra) being sold with that air controller. The Stealth pump was
`
`revolutionary for Sleep Number and became the new standard that we continued to
`
`improve on over time. Throughout the years, Sleep Number expanded the product
`
`offerings that incorporated the technology and added additional, complementary
`
`technology into its air controllers.
`
`In fact,
`
`it was always engineering’s goal to
`
`incorporate the technology into all of Sleep Number’s air controllers over time. By
`
`the time I left the company in July 2011, the plan was for all mattress models to soon
`
`be sold with the ‘ 172 Patent technology.

`

`19.
`
`The internal aspects of the enclosure of the valve enclosure assemblies
`
`used in Sleep Number’s air controllers were substantially the same throughout the
`
`early 20003. For example, the internal aspects ofthe enclosure ofthe valve enclosure
`
`assembly sold with the 5000/6000 air controller, which we called the Pegasus and
`
`which we sold between 2004 and 2008, would have been the same as the next air
`
`controller we introduced, which we called the Corolla and which we began selling
`
`in 2008.
`
`20.
`
`The ‘154 and ‘747 Patents disclose an improved pressure adjustment
`
`system and method through use of algorithm that allows for more quickly and more
`
`accurately reaching the user’s desired pressure.
`
`I also believe incorporating this
`
`technology was beneficial to, and desired by, consumers.
`
`In fact, we believed as a
`
`company that
`
`this
`
`technology was so important
`
`that Sleep Number began
`
`incorporating the ‘ 154 and ‘747 Patents into technology into most of Sleep Number’ 5
`
`air controllers very quickly after the patents were filed. It was always engineering’s
`
`goal-Ito incorporate the technology into all of Sleep Number’s air controllers over
`
`time. By the time I left the company in July 2011, the plan was for all mattress
`
`models to soon be sold with the ‘ 154 and ‘747 Patent technology.
