摘要： The invention relates to a serial data transfer method for exchanging data between two electronic bus stations. The bus connection consists of two lines, the first line being dedicated to data/control signals and the second line being dedicated to a power supply voltage. Data transfer is started by pulling the first line to an activated potential for a first period of time, and then leaving the first line inactive for a second period of time. Data transmission commences via the first and second lines after the second period of time has elapsed. Preferably, data is transferred in a number of blocks in the data frame.

摘要： The present system and method manage a rechargeable battery comprising two or more battery cells or series stacks of cells. The system includes a set of switches, each of which connects a cell or stack of cells between positive and negative nodes when actuated, or connects one cell in a stack of cells to another cell in the stack when actuated, such that when all the switches in a given stack are actuated, it is connected between the positive and negative nodes. An electrical load is directly connected to the positive and negative nodes. A controller determines the state of each cell or stack of cells by measuring and/or calculating one or more predetermined characteristics, and selectively actuates the switches based on the states of the cells or stacks of cells so as to enhance the life of the battery.

摘要： A transmitter power control system includes a voltage detector that generates a voltage signal that is proportional to an output voltage of a power amplifier of a transmitter. A voltage scaler scales the output voltage of the power amplifier using a voltage scaling ratio. A voltage scaling ratio controller adjusts the voltage scaling ratio to maintain the voltage signal within a predetermined voltage range. A current detector generates a current signal that is proportional to an output current of the power amplifier and includes a current scaler that scales the output current using a predetermined current scaling ratio. A power detector generates a power signal that is based on the current signal and the voltage signal and is proportional to an output power of the power amplifier. A power controller generates a control signal to vary the output power based on a comparison of the power signal with at least one predetermined threshold.
