Assignee:

Kelsey-Hayes Company - Livonia MI

International Classification:

B60T 8/86

US Classification:

303125, 303155

Abstract:

A method is provided for applying a soft-stop control to the vehicle brake actuators of a vehicle during a vehicle stop operation. A brake apply operation is detected. A determination is made whether the vehicle speed is below a first threshold stopping speed. Braking pressure to the vehicle actuators is reduced as a function of vehicle speed, vehicle deceleration, and brake apply pressure if the vehicle speed is below the first threshold stopping speed.

Abstract:

A method is provided for adaptively determining an anti-lock braking strategy that includes monitoring a distance differential of at least one target in proximity to a driven vehicle. An anti-lock braking strategy is determined as a function of the distance differential. The anti-locking braking strategy is applied as a function of the distance differential.

International Classification:

H03B 100

US Classification:

327108

Abstract:

Circuitry for controlling load current, in accordance with the present invention, utilizes a load drive transistor configuration operable to provide a first load current path having a first fraction of load current flowing therethrough and a second load current path having a second smaller fraction of load current flowing therethrough. The circuit includes a sense resistor associated with the load drive transistor to detect various load current threshold values. In order to reduce debiasing effects of the sense resistor upon the second load current path of the load drive transistor, a compensation resistor is provided between drive inputs associated with each of the two current paths. The compensation resistor has a compensation voltage established thereacross which is operable to negate the debiasing effect of the sense resistor on the load driving device.

International Classification:

G11C 2900

US Classification:

365201

Abstract:

A "zener-zap" memory cell with pretest capability for testing effects that would be realized from permanently programming the memory cell is provided. The memory cell is addressable and provides a binary signal at an output. The memory cell uses a zener diode as a memory element which is permanently programmed when selectively coupled to a programming voltage which exceeds the reverse breakdown voltage of the zener diode. The memory cell has a test circuit for generating the programmed binary signal at the output of the memory cell prior to permanently programming the zener diode and when coupled to a pretest voltage.

International Classification:

G05F 302

US Classification:

327538

Abstract:

A programmable current mirror circuit suitable for incorporation into circuit designs and programmably tailored to produce a ratio of current output over current input based upon the status of a plurality of binary weighted switches. The resulting circuit is readily tailored so as to be insensitive to the "on" characteristics of the switches. Alternatively, the switches may comprise transistors controlled by accompanying circuitry operable to produce an equivalent switching function. An input current divider circuit network formed from an array of current mirrors fractionally divides an input current into a plurality of equivalent currents. A binary weighting circuit receives such fractional input currents, and applies a binary weight to each of same. A voltage to current converter receives the binary weighted voltage and converts the voltage to a weighted output current proportional to the input current directly in relation to the binary weighting applied via the binary weighting circuit.

International Classification:

F03G 702

US Classification:

606418

Abstract:

A solar converter is disclosed which has particular applicability at the focal point of a parabolic concentrator. The converter absorbs solar thermal radiation in a cavity type receiver and transports the heat via a secondary fluid to a heat exchanger which contains a primary (i. e. , working) fluid used for process heating or to power a heat engine employing either Stirling, Rankine, or Brayton thermodynamic cycles. The secondary fluid is boiled within the receiver by the trapped solar radiation and the released vapor rises along an elevated path to the heat exchanger. The vapor condenses on the surfaces of the heat exchanger, thereby transferring heat to the engine working fluid. The condensed liquid then flows by means of gravity back to the solar receiver. The walls of the cavity receiver are typically comprised of two concentric cylinders joined at one end in a half toroid and at the other end in concentric half spheres.

US Classification:

327561

Abstract:

In accordance with the teachings of the present invention, a programmable integrated transducer amplifier circuit is provided which receives differential outputs from a transducer, such as a pressure or accelerometer transducer. The programmable integrated transducer amplifier circuit includes binary adjustable circuits that are programmed in response to binary coded signals. The binary adjustable circuits generate binary weighted currents that are employed to adjust the operating characteristics of the amplifier circuit. The binary coded signals are received from a programmable memory array which includes a plurality of memory cells that store binary information. Each of the memory cells are programmed when coupled to a programming signal. Additionally, the memory array has pretest capability for testing outputs of the memory cells prior to permanently programming the respective memory cells. Additionally, the integrated transducer amplifier circuit automatically compensates for variations in the operating temperature of the amplifier circuit.
