摘要： A booster-enhanced power supply for a valve control circuit is disclosed. An inductor repeatedly stores energy from a power source, then discharges it through a diode into a capacitor due to the cycling on and off of a switch. The charged capacitor is used as the power source for changing the state of the valve. The charge stored on the capacitor(s) at any given moment is preferably monitored, and the charging cycle is preferably controlled to optimize the use of the boosting circuit for a given application. The boosted power source can provide a consistent output even when the power source provides an consistent power output even when the power source provides an inconsistent power input.

摘要： A mortise lockset apparatus (10) that includes a retractable bolt (20) movably supported within a case (12). A handle (18) is pivotally supported on a hub (16) supported in the case, the hub being operably connected to the retractable bolt. The bolt is retracted by turning the door handle. A lock-out mechanism (22) is configured to prevent the handle from being turned when the lock-out mechanism is in an engaged position. The handle lock-out mechanism also includes a cam (29) movably supported in the case and operably connected to a motor (30). A sliding stop (34) is movably supported in the case and is engageable with the handle hub to prevent the handle hub and the handle from turning. The sliding stop is also engageable with a cam surface (40) of the cam. The motor is configured to move the sliding stop by rotating the cam. The cam rotational axis (42) is disposed between diametrically opposed portions of the cam surface to minimize space requirements for the assembly.

摘要： A key card encoder incorporates a plunger that is pushed downward as the card is manually inserted into a slot in the encoder and a potentiometer whose value changes based on the plunger position to indicate the card's position at all times. As the card is inserted into the slot, a head encodes a magnetic strip on the card as the card is inserted into the slot, while the head verifies the code in the reverse direction as the card is withdrawn from the slot. The slot is illuminated in different colors and flashing patterns to guide the user through the encoding process and notify the user if there is an encoding error.

摘要： An electrical control circuit detects a sensed value on a load and outputs an analog sensor signal. The analog sensor signal is passed through a plurality of isolation couplers which isolate a controller from a load. The plurality of isolation couplers are arranged such that the scaling factor of the first isolation coupler will cancel the scaling factor of the second isolation coupler.
