Patent number: 9237407Abstract: A multichannel wireless digital audio distribution system provides for the synchronization of the output of audio data by different receiving units set to output audio data for receiver unit assigned channels. The transmitter includes parallel data respectively representing a plurality of audio data channels in each data packet. The data packets are broadcast wirelessly with known, predetermined packets including a timing marker. Each receiver unit receives the broadcast data packets and selects the parallel data respectively representing the receiver unit assigned audio data channel. The receiver unit outputs the selected data synchronized to the receipt of the timing marker by the receiving unit.Type: GrantFiled: August 4, 2006Date of Patent: January 12, 2016Assignee: Summit Semiconductor, LLCInventors: Michael D. Hudson, Kelly M. McArthur

Patent number: 8660219Abstract: A radar detector determines whether an input signal is an orthogonally frequency division multiplexed (OFDM) signal or a radar signal by applying at least first and second bandpass filtering operations having substantially non-overlapping passbands to the input signal, each filtering operation having a passband of width substantially less than a relatively large instantaneous bandwidth characteristic of an OFDM signal and substantially greater than a relatively small instantaneous bandwidth characteristic of a radar signal. The detector multiplies power levels of output signals of the first and second filtering operations to form a power product signal and compares the power level of the power product signal with a threshold level and providing an indicating signal in a first state if the power level of the power product signal exceeds the threshold level and otherwise providing said indicating signal in a second state.Type: GrantFiled: April 3, 2012Date of Patent: February 25, 2014Assignee: Summit Semiconductor LLCInventor: Kenneth A.

Publication number: 20140043190Abstract: A planar inverted F antenna structure includes an insulating substrate having a main face, a ground plane conductor on the main face of the substrate, the ground plane conductor having a straight edge, and an antenna element on the main face of the substrate. The antenna element includes a feed portion, a ground return portion, and a radiative arm projecting from the feed portion and extending beside the straight edge of the ground plane conductor. A first edge of the antenna arm is a straight edge that is located between a second edge of the antenna arm and the straight edge of the ground plane conductor and is spaced from the straight edge of the ground plane conductor. The first edge of the antenna arm is inclined to the straight edge of the ground plane conductor.Type: ApplicationFiled: August 10, 2012Publication date: February 13, 2014Applicant: SUMMIT SEMICONDUCTOR LLCInventors: Krishna Prasad VUMMIDI MURALI, Ponnappa PASURA

Patent number: 8199941Abstract: With an array of speakers including a center speaker provided with left and right ultrasonic electro-acoustic transducers and left and right speakers provided with respective ultrasonic electro-acoustic transducers, it is possible to identify the left and right speakers. One approach includes energizing the left transducer of the center speaker to emit an acoustic ping signal, utilizing the transducers of the left and right speakers to detect the ping signal, measuring lapse of time between emission of the ping signal by said the left transducer and detection of the ping signal by the transducers of the left and right speakers. Then, the right transducer of the center speaker is energized to emit an acoustic ping signal, the transducers of the left and right speakers are utilized to detect the ping signal, and lapse of time between emission of the ping signal by the right transducer and detection of the ping signal by the transducers of the left and right speakers is measured.Type: GrantFiled: June 22, 2009Date of Patent: June 12, 2012Assignee: Summit Semiconductor LLCInventors: Michael D.
