Abstract: A detachable audio device structured to be coupled to an interface port of a computer system simulates the coupling and uncoupling of an audio controller to trigger an operating system being executed by a processing device of the computer system to select between an audio driver for that same audio controller and another audio driver for a different audio controller to which the processing device of the computer system has access, thus triggering a selection between causing audio played by the computer system to be acoustically output through either an acoustic driver to which the detachable audio device relays the audio or another acoustic driver associated with the other audio controller to which the processing device of the computer system has access.

Abstract: An apparatus and method for programming a universal remote control. The method includes receiving a transmitted signal of unknown modulation technique from a native remote control and characterizing the received signal in parameters of a pre-determined modulation technique.

Abstract: A method for an audio system controls a number of audio devices from a master device over a wired network for at least one wired audio device and over a wireless network for at least one wireless device. The method receives a reply in response to a poll message from each of the wired audio devices and aggregate polling information indicative of the state of the wireless devices from one of the wireless devices.

Abstract: Improved apparatus and methods of sensing or monitoring body orientation and motion and measuring range of motion (ROM) for use in athletic training and physical rehabilitation and evaluation. The apparatus includes a 3-axis sensor, at least one memory, and at least one processor, and is attachable to an object to be monitored. The 3-axis sensor senses a magnitude of tilt along each of a first, second, and third axis, the memory stores data representing the sensed magnitudes of tilt, and the processor processes the data stored in the memory. In one embodiment, the processor determines an angle between each of the first, second, and third axes and a horizontal plane, and selects the two axes corresponding to the two smallest angles between the three axes and the horizontal plane. The processor then generates an indication of the orientation of the object based upon the sensed magnitudes of tilt along the two selected axes.

Abstract: An audio system may include a plurality of sound reproduction devices characterized by parameter values; a plurality of audio signal sources characterized by parameter values; a plurality of remote control devices, a system controller, constructed and arranged to wirelessly receive command signals from the remote control devices and to wirelessly transmit parameter values of audio signal sources and of sound reproduction sources to the remote control device. The remote control devices are constructed and arranged for wirelessly transmitting command signals to the system controller and for wirelessly receiving parameter values and displaying parameter values. The remote control devices are being further constructed and arranged to transmit command signals to and receive parameter values from a system controller that is separated from remote control.
