Abstract: Some headphone systems include two ear cups, a headband assembly, an interface system and a control system. Each ear cup may include an ear cup enclosure, an ear pad assembly, a speaker system and a hinge assembly. The hinge assembly may be disposed within the ear cup enclosure such that it is not visible from outside the ear cup. The headband assembly may connect with each of the ear cups via the hinge assembly. The interface system may include at least one interface and a plurality of input source buttons disposed on at least one of the ear cups. Each of the input source buttons may be configured for selecting a source of audio data received via the at least one interface. The control system may be configured for controlling the speaker system to reproduce audio data received via the interface and selected by one of the input source buttons.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for wireless audio source switching. One of the methods includes receiving user input selecting a user interface control corresponding to one of a plurality of paired audio source devices with a wireless audio sink device that is a slave device of a first master/slave connection with a first paired audio source device of the plurality of paired audio source devices. The wireless audio sink device initiates a request to become a master device of a second master/slave connection with a second paired audio source device corresponding to the selected user interface control. The wireless audio sink device sends to the second paired audio source device a request to become a slave device of the second master/slave connection. The wireless audio sink device receives audio input from the second paired audio source device and outputs the received audio input.

Abstract: Devices, systems, and methods are provided for an ultra-short throw projector. The projector may include an illuminator having an ellipsoidal reflector, a light emitting diode (LED) positioned inside of the ellipsoidal reflector, and a Fresnel lens positioned inside of the ellipsoidal reflector. The projector may include a circular transmissive liquid crystal display (LCD) and a three-element plastic projection lens positioned outside of the ellipsoidal reflector, wherein the circular transmissive LCD is positioned between the ellipsoidal reflector and the three-element plastic projection lens, wherein the ellipsoidal reflector reflects light emitted by the LED, wherein the Fresnel lens refracts light emitted by the LED, and wherein the three-element plastic projection lens projects the reflected light and the refracted light.
