摘要： A three state switch detection circuit converts a three state input to a two-bit binary output readable by a micro-controller or other digital logic. The circuit utilized complementary NPN and PNP transistors having coupled emitters and coupled bases connected by a resistor. The collector of the PNP transistor is connected by a resistor to ground while a complementary resistor ties the collector of the NPN transistor to V.sub.BATT. Additional circuitry preferably converts the voltage output from the collectors to a suitable voltage level readable by the micro-controller or other digital logic device.

摘要： A double annular ring gasket (202) interfaces a speaker (201) to a housing (200) in a portable radiotelephone, providing a conformal and acoustic seal between the speaker (201) and the housing (200), and compensating for dimensional tolerance between the housing (200) and the circuit board subassembly (204) on which the speaker (201) is mounted. The gasket (201) includes outer ring (205), inner ring (206) and intermediate ring (207) therebetween. The gasket (202) is inserted into a cavity (203) in the housing (200). Then, the speaker (201), as part of a printed circuit board subassembly (204), is pressed into place against the outer ring (205) of gasket (202) to form an axial seal and the inner ring (206) is deformed radially by the speaker (201) to form a conformal seal.

摘要： The present invention advantageously provides a microprocessor controlled power delivery circuit with short circuit protection. The microprocessor controls the load current flow at the circuit's load connection terminal by connecting this terminal to the positive or negative side of a power supply or opening the circuit to prevent current flow. The short circuit protection uses a passive electrical component feedback circuit to communicate the voltage level at the circuit's load connection terminal back to the microprocessor. The microprocessor routinely monitors this voltage and compares this voltage against the expected voltage at this terminal. When the actual voltage does not match the expected voltage, the circuit will provide protection by interrupting current flow through the load connection terminal.
摘要翻译：本发明有利地提供了具有短路保护的微处理器控制的电力输送电路。微处理器通过将该端子连接到电源的正极或负极侧或打开电路来控制电路负载连接端子处的负载电流，以防止电流流动。短路保护使用无源电气部件反馈电路将电路负载连接端子处的电压电平传送回微处理器。微处理器通常监视该电压，并将该电压与该端子上的预期电压进行比较。当实际电压与预期电压不匹配时，电路将通过中断通过负载连接端子的电流来提供保护。
