Abstract: In the normal rotation direction, a change in the main sensing signal caused by a front edge is defined as a signal change caused by an effective edge, and a change in the main sensing signal caused by a back edge is defined as a signal change caused by an ineffective edge. In the reverse direction, a change in the main sensing signal caused by the back edge is defined as a signal change caused by an effective edge, and a change caused by a front edge is defined as a signal change caused by an ineffective edge. Regardless of the rotation direction, a detection signal generating circuit generates a detection signal including falling-edge changes and rising edge changes caused by the effective edge and ineffective edge respectively. When the direction is changed, the signal change on the detection signal is prohibited. As a result, gear tooth detection discrepancies are prevented.

Abstract: A portable door alarm having an alarm pushbutton switch extending from the back of the housing of the alarm has a first L-shaped member hingeably attached to a bottom portion of the housing. At the top of the first L-shaped member is a bracket hanger which fits over the top of a door. The first L-shaped member is biased to close the hinge, thereby placing the first L-shaped member in close proximity to the housing. A leg portion of a second L-shaped member, having a longitudinal portion attached to the back of the housing, is located above the hanger and pushes against a wall portion above the door once the device is placed on the door and the door is closed.

Abstract: Three adjacent disks carried by an "S" cam shaft of a truck brake system sense motion of system components beyond predetermined limits to indicate need for adjustment and parts replacement and annunciate such information at a distance from the brake system. A first outer disk journaled on the "S" cam shaft is interconnected to the slack adjuster arm to rotate responsive to motion of the slack adjuster arm.

The second medial disk carries two Hall effect switches to sense the rotary position of magnets carried in the first and third adjacent outer disks to determine motion of the slack adjuster arm and the "S" cam shaft beyond predetermined limits to indicate need for brake adjustment and brake shoe replacement. Sensed data is transmitted to an annunciator at a distance from the braking system.

Abstract: A hinge construction having radiative emitter and detector concealed within the body of the hinge's knuckles so as to be in communication with each other when the hinge leaves, and therefore the door, are in a closed position. This communication is permitted through an opening in a notched collar which is juxtaposed between the emitter and detector elements, the notch being aligned with the emitter and detector when the hinge is closed. The opening of the hinge leaves rotates the collar to misalign the collar notch with the emitter and detector elements, thereby causing an electronics circuit module to form a change of state signal which may then be reported to an external monitoring or alarm system. Closing the hinge leaves to realign the notch with the emitter and detector elements will result in the sensing means being reset.

Abstract: In an alarm control system for protecting a premises, a four conductor bus line leading from a master control station is extended about the interior perimeter of the premises. Sensors positioned near each port of entry to be monitored are connected in parallel relationship to the bus line, as is at least one remote station for manually arming, disarming or activating the system. Each sensor comprises a biased reel carrying line secured to window, door, screen, or the like.

The system then resets automatically to an armed or ready condition to continue protecting the premises against subsequent intrusions. Preferably, the lines in the sensors are of a thermoplastic material so that the system is also activated by abnormally high temperature in the event of fire.
