Patents by Inventor Eric Simpson

Eric Simpson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Haptic trackpad loudspeaker
    Patent number: 12560983
    Abstract: Current mobile devices that feature force feedback touchpads include haptic engines that operate in a narrow bandwidth and therefore cannot be used as a dual-purpose center channel for media playback. Further, a separate dedicated loudspeaker for a center channel would add cost and reduce integration space. The presently disclosed dual-use haptic trackpad loudspeaker can enable an enhanced audio experience without the need for an additional dedicated loudspeaker. The dual-use haptic trackpad loudspeaker can be used for haptics feedback as well as provide audio output over the frequency range 400 Hz to 10 kHz. The dual-use haptic trackpad loudspeaker may use a tuned spring-mass actuator and adopt mechanical properties to provide a specific desired mechanical compliance to the dual-use haptic trackpad loudspeaker.

  • Flow-stabilized wet scrubber system for treatment of process gases from semiconductor manufacturing operations
    Patent number: 5851293
    Abstract: A flow stabilization system for damping pressure variations in a process discharging an effluent gas stream, in which the process is pressure-sensitive and downstream pressure variations can adversely affect the upstream process, said system comprising a motive fluid driver constructed and arranged to receive the effluent gas stream from the process, and means for sensing a flow characteristic of the effluent gas stream and responsively adjusting the flow of the effluent gas stream to damp pressure fluctuations in the process.
