System and method for configuring an interior of a vehicle based on preferences provided with multiple mobile computing devices within the vehicle

Abstract: In response to detecting the entry condition, a determination is made as to when multiple mobile computing devices are present within the vehicle. An occupancy zone is determined for each multiple mobile computing device that is determined as being present within the vehicle. Profile information is determined for each mobile computing device. At least one of an operational or usage facet of the vehicle can be configured at each occupancy zone in which one of the mobile computing devices is determined to be present. The operational or usage facet of the vehicle at a location of each occupancy zone can be based at least in part on the profile information determined from the mobile computing device that is deemed to be present at that occupancy zone.

Methods and apparatus of power control in wireless communication systems

Abstract: The present invention involves apparatus and methods to perform wireless terminal transmission power control. The invention uses novel and highly efficient methods to: convey power control information, specify power control level adjustments, recognize power control information, limit interference in the power control signaling, and recognize corrupted power control signaling, thus conserving wireless terminal energy and minimizing power control signaling and associated bandwidth. Base stations send analog power control command signals, with a continuous range of control levels, to wireless terminals for transmission power adjustments. Power control signals include two components which can be used to convey information, e.g., power control commands, signal quality, device identity information. For zero power adjustment, the control component signal is not transmitted. For a non-zero adjustment, power control signals are sent using control ranges and limits, known to the base station and wireless terminal, with the scaling adjusted or synchronized based upon feedback information.

See through near-eye display

Abstract: The various embodiments include a near-eye display having a transmissive display and a diffractive micro-lens array. The transmissive display may be positioned relative to the diffractive micro-lens array so that the distance between the transmissive display and the diffractive micro-lens array is be approximately equal to focal length of the diffractive micro-lens array. The transmissive display may also be positioned relative to the diffractive micro-lens array so that a percentage of light emitted from the transmissive display is diffracted by the micro-lens array and collimated into focus on a retina of a human eye. The transmissive display may be further positioned relative to the diffractive micro-lens array so that light from a real world scene passes through transparent portions of the transmissive display and is diffracted by the micro-lens array out of focus of the human eye.

Systems, methods, and apparatus for producing a directional sound field

Abstract: A system may be used to drive an array of loudspeakers to produce a sound field that includes a source component, whose energy is concentrated along a first direction relative to the array, and a masking component that is based on an estimated intensity of the source component in a second direction that is different from the first direction.

System and method for routing voice over ip calls

Abstract: An SIP server (18) in an IP-based infrastructure supporting wireless telephones determines whether, based on the destination address in a call request, the call is an intrasystem call or an intersystem call. For intrasystem calls the SIP server routes VOIP packets directly between the originating and destination devices. For intersystem calls, however, and in particular encrypted calls, instead of routing the VOIP packets through the public Internet, the SIP server instantiates a circuit-switched call using a local modem bank (22) connected to the PSTN (24). In this way, quality of service assurance is obtained and latency reduced.
