Abstract:
In a driveline for a motor vehicle, an automatic transmission having an output shaft connected to a transfer case input, a planetary gearset, a coupler having positional states that alternatively produce a high speed range and low speed range, a friction clutch that alternatively driveably connects the output and a forward drive shaft, or releases the connection between the output and forward drive shaft, without regard to the positional state of the coupler or speed range produced by the transfer case.
Abstract:
In a driveline for a motor vehicle that includes an automatic transmission having an output shaft that drives a transfer case, an oil sump located in the transfer case, a pump supplied with fluid from the first sump, delivers fluid to a lubrication circuit in the transmission, a second sump supplies fluid to the inlet of a second pump, whose output supplies a second lubrication circuit located in the transfer case. Both of the hydraulic pumps are continually driveably connected to a set of the vehicle's drive wheels.
Abstract:
In a motor vehicle driveline including a transfer case whose output is continually connected to a first output, a clutch, operating partially engaged, responds to a control signal to change the degree of clutch engagement, whereby a second output is connected driveably to the first output. A digital computer, repetitively executing a computer readable program code algorithm for operating the clutch partially engaged, continually selects a desired magnitude of clutch engagement with reference to functions indexed by vehicle speed and either engine throttle position or engine throttle rate. The computer repetitively updates at frequent intervals the desired degree of clutch engagement, and issues a command clutch duty cycle to a solenoid-controlled valve, which signal changes the degree of clutch engagement in response to the command signal.
Abstract:
A method of braking an electric or hybrid vehicle 7 is provided. The vehicle (7) has electric regenerative brakes and friction brakes (94). In a normal braking situation regenerative brakes are applied. If a wheel (42) slip condition is sensed, a selectively operable clutch (76) tortionally connects an undriven axle (60) to the driven axles (44, 45) to alleviate the slip condition. The alleviation of the slip condition prevents the electric regenerative brakes from being shut off in favor of an antilock friction brake application.
Abstract:
A power supply according to the principles of the inventions comprises two stages. The first stage is a power factor corrector stage. This stage provides the required line regulation, including greater than 95% power factor correction, and provides a range of outputs from approximately 5 volts to 200 volts with good load regulation at low voltages. The second stage is a soft switching power supply having good load regulation from approximately 40 to approximately 175 volts. An intermediate high voltage of the first stage supplies the input to the second stage, thereby achieving extremely good line regulation and low regulation.

Abstract:
Provided is an electrostatic sensing chuck for attracting particles to a portion of a particle contact surface near a deposition electrode, the electrostatic sensing chuck comprising a pixel comprising: a deposition electrode (DE) for selectively establishing an attraction field (Ea) at the particle contact surface; a shield electrode (SE) oppositely biased with respect to the deposition electrode; a charge sensing circuit to measure charge accumulated on each of the deposition electrode and the shield electrode, wherein the charge sensing circuit subtracts a second charge it senses at the shield electrode from a first charge it senses at the deposition electrode, thereby determining accumulated charge at the deposition electrode balanced by accumulated charge at the shield electrode.
Abstract:
A system for testing integrated circuit chips includes a signal generator which generates a clock signal; and a sequential control circuit having a first input which receives the clock signal, a second input for receiving commands, and multiple outputs. A command source sends programmable sequences of the commands to the second input of the control circuit; and in response, the control circuit passes the clock signal from the first input to only certain outputs which the commands select. All of the outputs of the control circuit are coupled through respective clock transmitters to different chips which are to be tested; and so in response to the programmable commands, the clock signal is sent sequentially to the chips that are to be tested, in selectable subsets. By such sequencing, the total power dissipation of the chips that are tested can be regulated when the chips are of a type that dissipate a large amount of power when they receive the clock signal, but dissipate substantially less power when they do not receive the clock signal.

Abstract:
A porous inorganic oxide carrier body for immobilizing living cells is prepared from inorganic oxide particles such as clay particles. The particles have an average particle size of from 0.01 to 20 microns, and the carrier body has a total pore volume of 0.05 to 1.0 cc/g and an average pore diameter of 50 to 700 .ANG., and has substantially no pore volume in the range of 800 .ANG. or greater. The carrier is prepared by forming a mixture containing the particles, a liquid medium and optional ingredients including zeolite and activated carbon, and forming the mixture into a shaped carrier body which may be optionally dried and calcined. Typical shapes of the carrier include spheres, cylinders, rings, honeycombs and shaped monoliths. Bacteria and other microorganisms immobilized on the carrier are useful for treatment of contaminated waste streams or contaminated vapors, or for other uses for which microorganisms are used such as the synthesis of chemicals.
