Abstract: 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.

Abstract: A disk drive assembly includes a disk drive, one or more accelerometers, a control circuit, and an adaptive feed forward circuit. The one or more accelerometers generate acceleration signals that are used to detect rotational vibration (RV) events on the disk drive. The control circuit is configured to: generate one or more control signals, which are based on a control signal from a host system and a compensation signal from the adaptive feed forward circuit, and generate a position error signal (PES) that indicates an error in a position of a disk drive head relative to a center of a track. The adaptive feed forward circuit generates the compensation signal, which compensates for the detected RV events based on the acceleration signals and the PES. The compensation signal accounts for self-induced RV events generated by a SEEK operation that repositions the head to a new track, wherein feed forward adaption is not disturbed by the SEEK operation.
