摘要： PURPOSE: To immediately disconnect currents, to prevent the destruction of a switch or a load, and to use a power source with a single polarity by monitoring currents running through a current detecting switch, and detecting an excess current state. CONSTITUTION: Nodes 18 and 18' with a high voltage are mutually connected, and ground sides are mutually connected. Moreover, current switches S1 -S4 are connected with each load connecting lines L1 -L4 . Those current switches are controlled by signals supplied to gates G1 -G4 . The signal is supplied to the gates G1 and G4 of the switches S1 and S4 , and the corresponding switch is turned on in order to allow currents pass a load 14 along a direction shown by an arrow 25. On the other hand, the signal is transmitted to the gates G2 and G3 of the current switches S2 and S3 , and the state of the switch-off is continued.

摘要： A power window system employs a computer based control (12) that receives signals from a window position sensor (20). As the window (16) moves, the position sensor produces periodic signals as an output. The computer cyclically looks for a change in the frequency of the signals as an indication that the window is obstructed and decelerating. Based on the instantaneous deceleration, the computer recalls a stored value for motor force. The recalled forces are accumulated in synchronism with the position sensor output during the deceleration, manifesting the force applied to the obstruction as the window presses on it. The window is reversed when the accumulated force exceeds a stored value. The uppermost window position is a stored value for the position sensor output obtained when the window is closed for the first time. Each time the window is closed thereafter, an offset is added to that value, the sum defining the point at which the window engages the window seal. The offset is the change in the position sensor output signal as the window is slowed by the seal until the motor stops when a stored value of force is applied to the seal.

摘要： A power delivery circuit for supplying load current to a load includes a current switch connected on the high potential side of a load. In order to detect a current condition, such as an over-current condition in the load, a current sensing and detection circuit preferably cooperates with the current switch wherein such switch comprises a multicellular device with a plurality of terminals. Such terminals include a first main current terminal connected to a source of high potential, a second main current terminal connecting a majority of device cells to the load, a first auxiliary terminal connected at one end to a minority of device cells so as to provide a current generally proportional to the main device current, and a second auxiliary terminal connected at one end to a majority of device cells. The current detection circuit preferably comprises one branch connected between the first auxiliary terminal and ground and including, in serial circuit, a current-to-voltage converting resistor providing a voltage at one end approximately proportional to the main device current and a bias signal-controlled transimpedance device, and another branch connected between the second auxiliary terminal and ground and providing a bias signal for the transimpedance device in the first branch. In another embodiment, the first branch includes at least two transistors and a resistor serially connected between a current sense terminal of the MOSFET and a reference potential. The second branch also includes at least two serially connected transistors connected between a terminal of the MOSFET and the reference potential. The transistors ore cross-connected between branches and provide an inverted current mirror and a current mirror. Fifth and sixth transistors may also be included as part of the current sensing circuit.
