    摘要： According to some embodiments, a conducting layer is formed on a first wafer. An insulating layer is formed on a second wafer. The insulating layer includes a cavity and a conducting area may be formed in the second wafer proximate to the cavity. The side of the conducting layer opposite the first wafer is bonded to the side of the insulating layer opposite the second wafer. At least some of the first wafer is then removed, without removing at least some of the conducting layer, to form a conducting diaphragm that is substantially parallel to the second wafer. In this way, an amount of capacitance between the diaphragm and the conducting area may be measured to determine an amount of pressure being applied to the diaphragm.

    摘要： A device includes at least one semiconductor switching circuit connected to a power source and a load and at least one breaker switch integrated with the at least one semiconductor switching circuit. The breaker circuit may be connected in series with the at least one semiconductor switching circuit and the at least one breaker switch is configured to create an open circuit in less than about twenty microseconds of receipt of a predetermined threshold of semiconductor switch current to thereby prevent damage to the at least one semiconductor switching circuit or housing. A method of preventing damage to a semiconductor switching circuit or device is also presented.

    摘要： A programmable logic controller is disclosed. The programmable logic controller includes control circuitry integrally arranged with a current path and at least one micro electromechanical system (MEMS) switch disposed in the current path. The programmable logic controller further includes a hybrid arcless limiting technology (HALT) circuit connected in parallel with the at least one MEMS switch facilitating the opening of the at least one MEMS switch. The programmable logic controller also may include a MEMS switch and a voltage sensor for measuring the voltage across the MEMS switch. The MEMS switches are arranged to transmit or receive logic signals.
