    摘要: An apparatus includes an amplifier, an input port, a first modulator circuit connected to the input port, and a correction circuit. The correction circuit is configured to determine a common mode voltage of the input port and receive a first clock signal. The correction circuit is further configured to manipulate, based at least in part upon the common mode voltage of the input port, the first clock signal to generate a second clock signal. The second clock signal is produced for the first modulator circuit. The correction circuit is further configured to determine whether the second clock signal is out of phase with a third clock signal, and, based upon a determination that the second clock signal is out of phase with the third clock signal, reset the second clock signal.

    摘要: The present disclosure includes a pressure transducer comprising: a frame; a cantilevered beam; a resilient beam portion; a signal processing circuit; a wiring terminal; and a support member. The resilient beam portion anchors the cantilevered beam to the frame. The cantilevered beam moves in response to a pressure-induced force applied to the cantilevered beam and the resilient beam portion bends producing a strain within the resilient beam portion. The support member comprises a cavity and the signal processing circuit is entirely installed inside the cavity. There is a strain gauge diffused into, implanted into, and/or affixed to the resilient beam portion. The cavity of the support member includes a first aperture disposed along the first surface of the support member and the inner surface of the frame covers the first aperture.

    摘要: A system for testing a clock monitor includes a fault injection circuit, a control circuit, and a clock monitor circuit to evaluate a clock source signal from a clock source. The fault injection circuit is to modify or replace the clock source signal from the clock source to yield a modified clock signal, and send the modified clock signal to the clock monitor circuit. The clock monitor circuit is to receive an input clock signal, determine whether the input clock signal indicates a faulty clock source, and issue a clock corrective action if the input clock signal indicates a faulty clock source. The control circuit is to monitor for the clock corrective action, and determine, based on whether the clock corrective action is issued, whether the clock monitor circuit is operating correctly.

    摘要: Various embodiments include a fuse electrically connecting two connection regions comprising: a heat sink; a set of layers arranged on a surface of the heat sink, the set of layers including an electrically insulating layer arranged on the heat sink and an electrically conductive conductor layer arranged on a side of the insulation layer facing away from the heat sink; and an electrical connecting path between the connection regions. The surface of the heat sink defines two material cutouts. A portion of the heat sink arranged between the material cutouts forms a bridge element. The set of layers is disposed on the bridge element.

    摘要: Various embodiments may include a method for the automatic calibration of a smoke detector comprising: mounting the smoke detector in a channel with an aerosol flow, along with a reference smoke detector; calibrating the smoke detector with data received by the reference detector. The reference detector comprises a scattered light receiver and a scattered light transmitter defining a scattered light plane. The aerosol flow through the channel flows through the reference detector transversely to the scattered light plane.

    摘要: Various embodiments may include a long injector for fuel injection comprising: a base portion and an extension portion electrically connected to the base portion. An end of the extension portion may include an electrically conductive terminal with contact clips. The contact clips are spaced at a distance from each other or from a side wall of the electrically conductive terminal. An end of the base portion comprises electrical contacts positioned so each of the electrical contacts can slide into a contact clip of the electrically conductive terminal. The electrically conductive terminal includes a latch mechanism. An electrical connection between the base portion and the extension portion is created when the electrical contacts are inserted into the contact clip and held by the latch mechanism. The long injector further comprises an overmolded body encapsulating the electrical connection between the base portion and the extension portion.
