20110260839 | AUTONOMOUS BATTERY-FREE MICROWAVE FREQUENCY COMMUNICATION SYSTEM - An autonomous battery-free microwave frequency communication device which includes a capacitance, at least one antenna, a microwave energy harvesting system, a microwave frequency transceiver, and a control system. The energy harvesting system is configured to harvest and store microwave energy received via the antenna onto the capacitance. The transceiver is empowered by energy stored on the capacitance, and is configured to autonomously generate a microwave frequency carrier and to autonomously transmit information using the microwave frequency carrier according to a predetermined communications protocol via the antenna. The control system is empowered by energy stored on the capacitance, and is configured to provide information for transmission. Energy may be harvested from various communication forms, such as wireless network protocols or cellular communications. The frequency band from which energy is harvested may differ from the frequency band used for communications. The energy storage enables autonomous communications with external devices according to common or standard wireless communication protocols. | 10-27-2011 |

20120058727 | UN-TETHERED WIRELESS STEREO SPEAKER SYSTEM - A wireless speaker system configured to receive stereo audio information wirelessly transmitted by an audio source including first and second loudspeakers. The first loudspeaker establishes a bidirectional secondary wireless link with the audio source for receiving and acknowledging receipt of the stereo audio information. The first and second loudspeakers communicate with each other via a primary wireless link, and the first and second loudspeakers are configured to extract first and second audio channels, respectively, from the stereo audio information. A wireless audio system including an audio source and first and second loudspeakers, each having a wireless transceiver. The first and second loudspeakers communicate via a primary wireless link. The audio source communicates audio information to the first loudspeaker via a secondary wireless link which is configured according to a standard wireless protocol. The first loudspeaker is configured to acknowledge successful reception of audio information via the secondary wireless link. | 03-08-2012 |
20120087503 | MULTI-CHANNEL AUDIO OVER STANDARD WIRELESS PROTOCOL - A wireless multi-channel audio system including an audio source with a wireless transceiver configured to communicate according to a standard wireless protocol and an audio controller, which are collectively configured to establish wireless communications with multiple audio sinks via a corresponding wireless link, to assign each audio sink a corresponding audio channel, to synchronize timing with each audio sink, and to transmit audio information for each audio channel to a corresponding audio sink via a corresponding wireless link. The audio source may inquire as to supported audio parameters, such as sample rate and audio codec, and selects a commonly supported configuration. The audio source may separate audio information into queues for each audio channel for each audio sink. The audio source transmits frames with timestamps and a common start time for synchronization, and the audio sinks use this information to synchronize timing and remain virtually synchronized with each other. | 04-12-2012 |
20120218053 | PASSIVE DISCRETE TIME ANALOG FILTER - A discrete-time analog filter including multiple storage cells each coupled to common input and output ports and each including at least one of capacitor and at least one switch. Each cell periodically samples an input signal and contributes to an output signal. At least two cells sample the input signal at different frequencies. The cells may be grouped together into one or more filter taps, where each filter tap may have a specified timing delay. Timing signals of a given tap may be non-overlapping phases of a given frequency. Cells may have a fixed or programmable capacitance associated with a corresponding weighting coefficient, and different taps may have different weighting coefficients. Taps may be coupled to implement a negative weighting coefficient. Programmable gain may be implemented with switches or by tap output coupling including sub-filter summing arrangements. Self-timed cells based on a master clock are disclosed. | 08-30-2012 |
20140329468 | UN-TETHERED WIRELESS AUDIO SYSTEM - A wireless speaker audio system configured to receive audio information wirelessly transmitted by an audio source including first and second wireless transceivers. The first wireless transceiver establishes a bidirectional secondary wireless link with the audio source for receiving and acknowledging receipt of the audio information. The first and second wireless transceivers communicate with each other via a primary wireless link. A wireless audio system including an audio source and first and second wireless transceivers. The first and second wireless transceivers communicate via a primary wireless link. The audio source communicates audio information to the first wireless transceiver via a secondary wireless link which is configured according to a standard wireless protocol. The first wireless transceiver is configured to acknowledge successful reception of audio information via the secondary wireless link. | 11-06-2014 |
