Abstract: A laptop computer is supplied with special-purpose software that detects when the cover is being closed by an unauthorized person. When the cover is closed, an alarm sounds using the speaker integral the laptop. The closed-cover condition is detected. The software operates on either interrupt-driven devices or polled devices which have some means for detecting that the cover is closed. The software includes a password feature and a hot-key feature for overriding the alarm so that an authorized person may close the cover without disturbing other persons or to stop the alarm if the authorized person forgets to disable the alarm.

Abstract: A patch cord tracing system and method for tracing patch cords in a telecommunications patching system. The system includes a plurality of tracing interface modules that attach to the patch panels in a telecommunications closet. On the patch panels in a telecommunications closet are located a plurality of connector ports that receive the terminated ends of patch cords. The tracing interface modules mount to the patch panels and provide a sensor, an LED and a tracing button to each of the connector ports. The sensor detects whenever a patch cord is connected to, or removed from, a connector port. Accordingly, by connecting a computer controller to the various sensors, the computer controller can monitor and log all changes to the patch cord interconnections in an automated fashion.

Abstract: A trailer hitching system (10) and method is provided for facilitating an operator's maneuvering of a towing vehicle hitch component (16) into alignment with a towed vehicle hitch component (18) to enable mechanical interconnection of the hitch components. The trailer hitching system (10) includes an alignment sensor (24) attached to either the towing vehicle (12) or the towed vehicle (14) for emitting a light beam over a field of view. A reflector (32) attached to the other of the towing vehicle (12) or the towed vehicle (14) is mounted at a predetermined location relative to the alignment sensor (24).

Abstract: The distance between a cash cassette and the person who is handling the cassette is measured automatically in case that there is a risk that a cash cassette may be stolen during a burglary. When the distance equals or exceeds a predetermined distance, it is concluded that a burglary has occurred, and various burglary alarm devices are activated. Accordingly, even when only one person performs a cash cassette exchange at a location which is easily accessible to other people, the commission of a crime can be immediately detected, so that the theft of a cash cassette during a burglary can be prevented. Therefore, the number of persons required for a cash cassette exchange can be reduced, which results to a reduction of operating costs. Further, since extra space is not required for a cash cassette exchange, restriction of a choice of an installation location for an automatic transaction apparatus can be considerably reduced.

Abstract: An untied shoelace warning system with a shoelace receiver and first and second sensors coupled to an indicator that activates when the system senses a shoelace segment, but senses it in an untied condition. The first and second sensors couple the indicator to a battery, and may all be contained within a housing. The first sensor is normally closed, but opens when a shoelace segment rests against it in a tied condition, and closes if the shoelace segment falls off the sensor, activating the indicator by coupling it to the battery. The second sensor is normally open, closing when it detects a shoelace segment. The system activates the indicator when a shoelace segment is not sensed by the first sensor, but is sensed by the second sensor. The system does not activate the indicator when a shoelace segment is not in the system, because neither the first nor the second sensor senses the shoelace. This way, the untied shoelace warning system does not activate the indicator when the shoe is not being worn.

Abstract: The present invention signals the power on, mated, and activity status of storage units in a console rack-mounted memory system. The status is signalled using parallel-coupled LEDs activated by logically combined signals provided by a logic circuit using signals available from SCA connector pins that connect the storage units to the console rack. The SCA connector provides MATED1 (pin 44), MATED2 (pin 74), and LED ACTIVE (pin 77) signals that are logically ANDed by the logic circuits. A logic circuit lights an associated parallel-coupled LED pair for a storage unit when LIT=MATED.multidot.ACTIVE LED, where MATED=0 denotes grounded pins 74 and (optionally) 44, and ACTIVE LED=0 denotes grounded pin 77, and LIT=l denotes lit LEDs. A steadily lit LED pair denotes that a storage unit is mated into the console rack and is inactive. An intermittent LED pair denotes that the storage unit is mated into the console rack and is presently active (and thus should not be removed).

The first main component contains an internally-disposed continuous loop alarm circuit and is attachable to a first object that is to be protected against an unauthorized removal thereof. The second main component replaceably engages the first main component, by non-magnetic means, and contains an internally-disposed circuit and is attachable to a second object. The internally-disposed continuous loop alarm circuit of the first main component is in electrical communication with the internally-disposed circuit of the second main component when the first main component is engaged with the second main component, so that when the first main component and the second main component are separated from each other the internally-disposed continuous loop alarm circuit of the first main component activates an alarm and since the first main component remains with the first object, location of the first object is facilitated.

Abstract: A portable multi-purpose device for monitoring patient movement in a number of different ways. The device includes a data processor programmed to respond to signals from multiple different external sensors that easily connect to the device through a jack in the device housing. If patient movement beyond a limit is sensed, the device generates an alarm for an attendant. To sense the different types of patient movement, one sensor is simply substituted for another. Examples of sensors include tether, door monitoring, and weight sensors. The device protects against unauthorized disabling of the sensors by sounding an alarm if a sensor is unplugged from the device impermissibly. The device provides power to sensors that require power to operate, reducing the need for additional power sources. The device also stores patient data (e.g., number of alarms, time before attendance response, etc.) during a given time period for evaluating a patient's care.
