摘要： Various energy harvesting and control techniques are used to power and control electronic accessories from the audio output channels and microphone input channel of mobile digital devices while preserving audio input and output functionality. One technique uses one of the stereophonic audio channels to generate power, and the other in conjunction with the microphone jack to enable bi-directional communications while preserving audio input and output. Another technique allows a low powered electronic accessory with bi-directional communications to be supported while simultaneously supporting audio input & stereo output. These techniques facilitate the ability to play music, narration and instruction and to receive oral responses and instruction with no perceived loss or gaps, even while using the audio jack of a mobile digital device to harvest energy and bi-directional communication.

摘要： A method for securing wireless communication between an in-vehicle system and multiple portable devices brought into a vehicle. The method can include receiving a communication request from a portable device, and determining whether a primary device has authorized wireless communication between the in-vehicle system and the portable device requesting communication, where such authorization can be provided via near field communication (NFC). The method can further include establishing wireless communication between the in-vehicle system and the portable device requesting communication when the portable device requesting communication is the primary device, and when the portable device requesting communication is a secondary device and the primary device has authorized wireless communication via NFC.

摘要： According to one aspect, a method includes determining when a first device and a second device are in proximity to each other, wherein the first device includes a first microphone and the second device includes a second microphone. The method also includes pairing the first device and the second device, and creating a mobile mapping of the physical relationship between the first device and the second device. Pairing the first device and the second device forms a microphone array that includes the first microphone and the second microphone. An aggregate stream is created using a first stream obtained from the first microphone and a second stream obtained from the second microphone. Creating the aggregate stream includes using the model mapping to determine when to use the first stream and when to use the second stream. Finally, the method also includes transmitting the aggregate stream.

摘要： Electronic circuitry supports utilization of a series of pulses of varying width to tune a transducer (e.g., a coil that produces or receives a magnetic field) for transmitting or receiving. For example, a control voltage generator generates a sequence of digital pulses of varying pulse widths to produce respective control voltages. The control voltage generator applies a produced control voltage to a varactor element whose capacitance changes depending on a magnitude of the produced control voltage. The varactor element forms part of a tank circuit. Consequently, the series of pulse widths controls an operating frequency of the tank circuit at different times. The tank circuit includes an inductive coil that is tuned to produce or receive a magnetic or inductive field.

摘要： A short range magnetically coupled wireless communication system employs time variant modulation of a high repetition rate pulse stream and magnetic coupling between a transmission magnetic element and a receiving magnetic element. The pulse stream is modulated by an input audio frequency signal in the time domain, for example, through pulse position modulation, pulse width modulation or pulse symmetry modulation. The receiving magnetic element is coupled to a demodulator circuit which detects the transmitted pulses induced in the receiving magnetic element and reproduces the audio frequency signal. Transmission over short range is thus efficiently accomplished through magnetic coupling in a simple, low cost, low power consumption communication system.
