Abstract: Active shutter 3D glasses with multiple optical detectors, such as photodiodes, are described that detect a frame rate of a 3D television or other 3D display by using independent component analysis. The detected frame rate is used to update a clock onboard the 3D glasses that times the active shutters, thereby synchronizing the shutters to the 3D display. A switch can reverse the shutters in case the left eye/right eye images are shown oppositely.

Abstract: A headphone device includes a first and a second ear piece coupled to an assembly, wherein the assembly facilitates the placement of the first and second ear piece in relation to a user's ears. A motion transducer is coupled to the first or second ear piece, whereby the motion transducer measures real-time pitch and roll movement associated with the user's head. An electronic compass is also coupled to the first or second ear piece, and measures real-time yaw movement associated with the user's head. A processing device associated with each of the first and second ear piece processes an audio signal according to a head-related-transfer-function selected from a plurality of head-related-transfer-functions on the basis of the measured pitch, roll, and yaw movement of the user's head. The processed audio signal is then applied to the first and second ear piece, and generates a virtual three-dimensional sound corresponding to the selected head-related-transfer-function.

Abstract: Methods and systems for communicating information through a USB device with A/D converters are presented. Active components which provide analog signals to the A/D converters are switched off to cause spikes in the analog signals/channels. The spikes are digitized by the A/D converters and sent to the host through a USB interface. The active components are switched on and off in a pattern corresponding to a message, such that the host can determine the message from the resulting spikes. If multiple active components and A/D converters are used, then multiple ‘bits’ can be transmitted simultaneously using the different channels.

Abstract: Sound processing methods and apparatus are provided. A sound capture unit is configured to identify one or more sound sources. The sound capture unit generates data capable of being analyzed to determine a listening zone at which to process sound to the substantial exclusion of sounds outside the listening zone. Sound captured and processed for the listening zone may be used for interactivity with the computer program. The listening zone may be adjusted based on the location of a sound source. One or more listening zones may be pre-calibrated. The apparatus may optionally include an image capture unit configured to capture one or more image frames. The listening zone may be adjusted based on the image. A video game unit may be controlled by generating inertial, optical and/or acoustic signals with a controller and tracking a position and/or orientation of the controller using the inertial, acoustic and/or optical signal.

Abstract: A magnetic input apparatus and method for a computer device are disclosed. A grid pattern of magnetic sensors can include a plurality of Hall elements. Each Hall element is selectively coupled to a Hall voltage sensor. A source of magnetic field can be placed in proximity to the grid pattern and one or more Hall voltage measurements for one or more of the regions can be collected with the Hall voltage sensor. The measurements can be analyzed to determine a position of the source of the magnetic field with respect to the grid pattern. Input can be provided to the computer program based on the determined position of the source of the magnetic field.

Abstract: A printed circuit board (PCB) antenna assembly having a metal shroud and a method of making the same are presented. The shroud reduces radio frequency (RF) interference from the rear of the PCB antenna while not introducing unwanted nulls in front of the antenna. The metal shroud has a back panel and two angled side panels and is set so that the back panel is parallel to the PCB antenna and set at a determined distance from the PCB antenna. The shroud can be formed by applying a metallized paint to a non-conducting cover with properly oriented surfaces.

Abstract: 3D shutter glasses with a synchronization signal sent through a stereo headphone wire are presented. In some embodiments, the 3D shutter glasses receive a synchronization signal through the same wire that transmits audio data to headphones or other audio devices. The synchronization signal may be combined with the audio data through various techniques so as to not disrupt the audio a listener hears, but to still provide the data to the 3D shutter glasses to synchronize with a display.
