摘要： A cold start air control device for an internal combustion engine of the type having an air delivery system in which the delivery of air to a vacuum generating manifold is controlled by a throttle valve and a by-pass valve and parallel with the throttle valve includes a casing that defines a passageway in parallel with the throttle valve and the by-pass valve and which has a cross-sectional area greater than that of the by-pass valve so as to offer a less restricted air flow path than that offered by the by-pass valve. The passageway provides communication between the manifold and atmosphere and a valve is disposed within the passageway for opening and closing the passageway in response to the vacuum level generated by the manifold.

摘要： A system for determining a quality and/or depth of a fluid in a tank. The system includes a controller, one or more transducers, and a temperature sensor. A fixed distance transducer transmits a sound wave toward a fixed surface. A depth transducer transmits a sound wave which reflects off a surface of the fluid. The temperature sensor senses a temperature of the fluid in the tank and provides an indication of the temperature to the controller. The controller measures the elapsed time for the sound waves to travel between the fixed distance transducer and a fixed surface and the elapsed time for the sound waves to travel between the depth transducer and the surface of the fluid held within the container. Using the elapsed times and the temperature of the fluid, the controller is able to determine a quality and the depth of the fluid.

摘要： A level sensor includes a first transducer generating a first signal, a second transducer generating a second signal, and a processor configured to switch operation between a first mode and a second mode. In the first mode, the first transducer generates the first signal and the second transducer senses a reflection of the first signal from a surface. In the second mode, the second transducer generates the second signal and the first transducer senses a reflection of the second signal from a reference target. The processor determines a distance to the surface.

摘要： A system for displaying the status of accessory systems is claimed. At least one sensor monitors the status of at least one accessory system. A transmitter located in proximity of the sensor transmits status information from the sensor to a receiver. The receiver is located remotely from the sensor and the transmitter. The receiver processes the status information and transmits the status information to a visual display.

摘要： A circuit with two terminals that receive an input current. The circuit includes a sensor, and a controller to generate a modulated signal. The circuit also includes a flyback circuit that receives the modulated signal. The flyback circuit generates a first output voltage based on the modulated signal, shunts or redistributes at least a portion of the input current, and enables the controller to regulate the input current in proportion to the modulated signal.

摘要： A sensor having a first array of N magnetic pole pairs, where N is a positive number, and a second array of M magnetic pole pairs, arranged substantially in parallel to the first array, where M is a positive number different from N, such as N−1 or N+1. A first magnetic pole in the second array is aligned with a first magnetic pole in the first array. The remaining magnetic poles in the second array are arranged such that each one of them is positioned with respect to at least one pole in the first array to form a magnetic field with an angular orientation with respect to the two poles. This arrangement of magnetic pole pairs can be used to measure absolute position. A third array of M magnetic pole pairs may be arranged substantially in parallel with the second array. The second and third arrays of magnetic pole pairs may be used to measure relative position between the two arrays.
