Abstract: In a power window device, a DOWN switch has first and second switches in a power window circuit located in a door for a window of a passenger's seat. A normally-closed contact of the first switch and a remote UP terminal of the power window circuit to which an UP signal is applied from a power window circuit provided near the driver's seat are connected. A normally-closed contact of the second switch and a remote DOWN terminal of the power window circuit to which a DOWN signal is applied from the power window circuit are connected. When the DOWN switch is manually operated, a signal supply line to which the UP signal and the DOWN signal are applied and a power supply line to which a power source is connected are electrically disconnected. As a result, the power window device is operable even when the signal supply line is grounded due to submerging in water.

Abstract: A hybrid vehicle comprises a motor driving the vehicle's wheels, multiple batteries supplying electric power to the motor, and a generator driven by an internal combustion engine to generate electric power for charging the batteries. Battery sensors detect terminal voltages of the batteries. An ECU controls a DC/DC converter to distribute electric power to independently charge the batteries through charge lines in accordance with the shortage of charge in respective batteries when excess electrical power is available from the generator even after a required amount of electrical power from the generator is used to rotate wheels.

Abstract: A multipole magnetic encoder is movable past two fixed analog sensors delivering sinusoidal signals (S.sub.1, S.sub.2) phase-shifted by .pi./2. A generator produces 2n sinusoidal signals (S.sub.i) of the same amplitude (A) as the signals (S.sub.1, S.sub.2), phase-shifted by .pi./n. An analog multiplexer delivers a signal (S) consisting of 2n successive portions of signals (S.sub.i). An acquisition device determines a maximum envelope (E) of the signals (S.sub.i). Two of switching thresholds (L.sub.i) and (L.sub.j) are generated proportional to the envelope (E). Two comparators compare the signal (S) with the thresholds (L.sub.i) and (L.sub.j), and deliver binary signals (A.sub.i) and (B.sub.j). Two combining devices combine the binary signals (A.sub.i) and (B.sub.j), each delivering a high resolution signal of 2m*n periods in the interval of one period of one of the sensors.

Abstract: Multiple pairs of stationary and moveable contacts are toggled simultaneously between an open and closed position to disconnect or connect a meter from or to a line power source, by a reciprocating operator driven by low power clock motor. The operator is connected to the contacts through a series of pivotally coupled toggle links that are spring biased to maintain the contacts in either of two stable states, open or closed. The disconnect switch is housed as a modular unit that is interposed between the meter socket and the meter. The switch is remotely actuated and cycles the motor through a pre-determined number of degrees of rotation sufficient to change the state of the contacts.

Abstract: When an inclination switch SW3 is turned on by inclining a wristwatch 12 up at 12 o'clock within a predetermined time after an acceleration switch SW2 is turned on in a state where an auto mode on/off subswitch SW1-1 is on, a lighting circuit lights up an electroluminescence panel EL and puts off same automatically after a predetermined time has passed. If the auto mode subswitch SW1-1 is off, there is no possibility that the panel EL will be lighted up even when the user makes a motion to look at the time displayed on the wristwatch. As a result, the panel EL is not recklessly lighted up excluding by the user's intended motion, useless power consumption is suppressed to prolong the life of a battery used.

Abstract: A self-powered back-up alarm for mounting to the wheel hub of a heavy truck or like vehicle. The alarm includes a housing adapted to be mounted to a vehicle wheel hub. Inside the housing is a magnetized stator that is held stable by a counterweight mounted for free rotation to a spindle in the housing. Also mounted in the housing is a power supply including a coil positioned adjacent the stator in the housing and attached thereto so that it rotates about the stator when the wheel hub turns. A battery stores the energy developed across the coil when the wheel hub rotates. Also mounted inside the housing are sensors located adjacent the stator that similarly rotate with the wheel hub. The sensors, in combination with an associated detect circuit, produce a reverse motion signal whenever the vehicle backs up. An audio alarm, located in the housing, is actuated by the reverse motion signal and emits an audible warning whenever the vehicle backs up.

The device comprises a cover member including an outer surface having a generally cylindrical, longitudinally elongate, non-rotatable protusion carried thereon. The protrusion projects outwardly from the outer surface and is provided with an outer periphery thereon. The device further includes a plurality of generally longitudinally elongate, circumferentially spaced, sensing means which are positioned adjacent the outer periphery of the protrusion and are responsive to the rotary hand movement of the operator for providing output signals corresponding to such movement. In addition, the device includes means coupled to the sensing means for leading the signals generated in the sensing means away from the switch device.

Abstract: A motor and manual actuated switch includes a motor control circuit for controlling the motor to rotate in either a clockwise or counterclockwise direction to actuate a mechanical switch between the open circuit and short circuit states. The control circuit includes a capacitor coupled in series with the motor winding to form a series circuit and a control switch for connecting a source of d.c. power across said serial circuit when in a first position and a short circuit across said series circuit when in a second position. When the control switch is moved to the first position, the capacitor charges, causing a current to flow through the motor winding during the charge time, thereby causing rotation in one direction. When the control switch is moved to the second position, the capacitor discharges through the winding, thereby causing opposite current flow and shaft rotation.

Abstract: A rotary drive mechanism has a yoke mounted on a motor shaft which engages a crank connected to a device to be rotated, such as the rotary portion of a microwave switch. When the gear motor is activated, the yoke causes the crank to move from a first position to a position past top dead center. A spring connected to the crank causes the crank to snap from the position past top dead center to a second position. A microswitch at the second position provides a signal to brake the motor when the crank reaches the second position. The yoke is configured like a V with the attachment point to the motor being the base of the V. A post from the crank is contained within the area defined by the legs of the V at a point where the shaft will not contact the opposite leg when the crank passes top dead center and is snapped to the second position.

Abstract: A driving mechanism, preferably provided for a high-voltage isolating switch (T), contains a driving motor (M) which acts upon a moving contact of the switch via a shaft (W) and is provided with a rotor winding (R) and a stator winding (S), connected in series. To control a direction of rotation of the driving motor (M) in dependence on the position of the switch, the driving mechanism also contains a control circuit. In this driving mechanism, it is intended to keep the number of cores of a connecting cable (L) from the driving mechanism housing (K) to a control cabinet (N) as small as possible.

Abstract: This disclosure relates to a directional sensing arrangement including a rotatable member having a plurality of permanent magnets which magnetically influence a first and second spaced stationary sensor.
