Abstract: A static RAM has an internal low voltage transformation circuit. The static RAM may comprise a word line drive circuit (1) which applies a low voltage (VINT) produced by the internal low voltage transformation circuit to a word line (WL) during read-out to improve an operating margin. The internal low voltage transformation circuit may be formed by a reference voltage supply circuit (51-Figure 5) and an internal voltage control circuit (52-Figure 5) and, when the static RAM is operating at a lower voltage, a data hold voltage may be supplied by a power pull-down device (M41-Figure 5) having a lower power consumption than the internal low voltage transformation circuit to achieve a saving in power consumption.

Abstract: In an engine having direct fuel injection or injection at individual intake ports, the fuel injectors (10) are of the positive displacement type and are equipped with plunger (30) displacement sensors (42) to yield a displacement signal representing the quantity of fuel injected. This signal is used as a feedback to a closed loop PID control which compares the injected quantity to a demand quantity to determine an error and calculates a control pulsewidth which reduces the error eventually to zero. An open loop injector calibration of pulsewidth versus approximate fuel quantity is used as a base pulsewidth to which the closed loop adds a correction value.

Abstract: An interfacing device for connecting the processing unit of a computer games system to an external data storage medium has a user-operable selection unit for generating a user-selected address and user-selected data. The user-operable selection unit may comprise user-operable switches or electronic latches that are set by a program in response to selections made by the user by means of a joystick, keypad or any other input device. An address comparison unit compares the user-selected address with the addresses from the processing unit, and a data switching device causes the user-selected data to be substituted for data in the storage medium whenever the compared addresses are the same. Instead of a user-operable selection unit, preselected addresses and preselected data may be stored in a ROM, which in one embodiment changes the way the computer interprets external memory and in another changes the computer's internal memory itself.

Abstract: A drive apparatus (10) which electrically isolates logic level and high-side circuits and detects high side power device fault conditions at the isolated, logic level side of the circuit. When an overvoltage or overcurrent condition occurs at the power semiconductor device (12), a protection circuit (22) disables the conduction of current through the current carrying terminals of the power device, preventing damage from occurring to the device. Activation of the protection circuit effects an increased current flow in the secondary and primary coils of the isolation transformer (16) between the low side and high side elements. Voltage at the primary coil of the isolation transformer is monitored by low level circuitry (24) to detect the rise in current, indicating a fault to the system controller upon detection.
