摘要： A system controlled by firmware includes a memory and a processor. The memory includes a first memory block for storing non-programmable code used for performing key functions, and second and third memory blocks for storing programmable code used for performing normal functions. During operation, one of the second and third memory blocks in which the programmable code is being executed is an active memory block. After receiving new programmable code, the processor identifies the inactive memory block, stores the new programmable code therein, and switches to execute the new programmable code while continuing to perform the key functions using the non-programmable code.

摘要： The embodiments described herein provide a power transmitter for wireless charging of an electronic device and methods of its operation. The power transmitter uses an inverter configured to generate a square wave from a potentially wide ranging DC input voltage. The inverter is configured to generate the square wave with a duty cycle that results in a desired equivalent voltage output, effectively independent of the DC input voltage that is provided. Thus, by generating a square wave with a selectable duty cycle the inverter provides the ability to facilitate wireless power transfer with a wide range of DC input voltages. Furthermore, in some embodiments the power transmitter may provide improved power transfer efficiency using a quasi-resonant phase shift control strategy with adjustable dead time and a matching network that is dynamically selectable to more effectively couple with the transmitter coil combination being used to transmit power to the electronic device.

摘要： An apparatus for measuring movement of an object has a quadrature incremental encoder for providing first and second phases of encoder pulses corresponding to incremental displacements of the object. A first counter counts edges of the encoder pulses according to the sense of the displacement. Clock pulse counts are also made. Acquiring movement data at periodic speed processing moments includes the decoder adjusting encoder pulse data from the first counter using a clock pulse count that is a function of a lapse of time between when the most recent edge of the encoder pulses and the speed processing moment. The clock pulse counts are reset by edges of the first and second phases of the encoder pulses when the decoder acquires the movement data.

摘要： A system and method for demodulating a wireless power signal onto which binary data has been modulated involves processing the wireless power signal with analog circuitry to produce a modified power signal in accordance with the type of demodulation used, periodically capturing digital samples of the modified power signal to produce a series of digital samples, applying, with an MCU, at least two digital filtering algorithms to the digital samples to determine transitions associated with the modulation, and recovering, with the MCU, the binary data as a function of the determined transitions. The demodulator is applicable to bidirectional power transfer capable devices and includes algorithms that can be applied similarly to both ASK and FSK demodulations with little or no modification.
