摘要： A system and method for determining an attitude of a device undergoing dynamic acceleration is provided. A first attitude measurement may be calculated based on a magnetic field measurement received from a magnetometer of the device and a first acceleration measurement received from a first accelerometer of the device. A second attitude measurement can be calculated based on the magnetic field measurement received from the magnetometer and a second acceleration measurement received from a second accelerometer of the device. A correction factor, calculated based on a difference between the two attitude measurements, can be applied to the first attitude measurement to produce a corrected device attitude measurement. The device can be a headset having two sets of in-the-ear and behind-the-ear microphones, a digital signal processor, and a communications interface. The device may comprise two hearing aids, each having multiple microphones, configured to wirelessly intercommunicate.

摘要： Spatial and temporal characteristics of received radio signals in a multiple user radio system can be estimated based on signals received from the users. In one embodiment, the invention includes collecting measurements of radio frequency signals received at different elements of an antenna system over time, the received signals corresponding at least in part to transmissions received from a system user, collecting representations of the transmissions of the system user, and comparing the representations to the collected measurements to form a spatial characterization of the radio channel traversed by transmissions of the system user in which the elements of the spatial characterization represent forming a beam in the direction of the system user and directing nulls to interferers.

摘要： A computer system stores calibration information corresponding to respective sets of sensor measurements associated with respective operating environments. After storing, in a first data structure, calibration information for a first operating environment, the system determines a current operating environment of the device. When the current operating environment of the device is consistent with the first operating environment and that the calibration information for the first operating environment meets predefined measurement diversity criteria, the system calibrates at least one sensor for the first operating environment using the stored calibration information for the first operating environment. When the current operating environment of the device is inconsistent with the first operating environment, the system excludes the stored calibration information for the first operating environment when calibrating one or more sensors for the current operating environment.

摘要： A computer system having one or more processors and memory receives data corresponding to a device-selection command performed at a remote control, where the remote control is configured to provide remote-control commands to a plurality of devices. In response to receiving the data corresponding to the device-selection command, the computer system selects one of the devices as a selected device in accordance with information indicating that the remote control was pointed at a proxy for the selected device at the time that the device-selection command was performed at the remote control, where the proxy for the selected device is at a different location than the selected device. The computer system also generates a respective remote-control command for the selected device, where the respective remote-control command will, when received by the selected device, cause the selected device to perform a predefined operation that corresponds to the respective remote-control command.

In one embodiment, the invention includes measuring radio frequency signals received at different elements of an antenna system over time, the received signals corresponding at least in part to transmissions received from a system user, accumulating the signal measurements into a first matrix, and generating a second matrix representing the transmissions of the system user. The invention further includes cross-correlating the first and second matrices to form a first cross-correlation matrix, cross-correlating the first matrix with itself to form a second cross-correlation matrix, and multiplying the second cross-correlation matrix with a product of the first cross-correlation matrix to form a fifth matrix in which the elements of the fifth matrix characterize the radio channel traversed by transmissions of the system user.
