Abstract: An alarm and bolt apparatus for a building opening closure panel hingedly mounted within a perimeter frame in a building opening includes a bolt assembly having a bolt and a mechanism for extending and retracting the bolt, a bolt receiving housing fitted into the closure panel frame, the housing having a forward wall portion with a bolt receiving opening, a side wall portion and a rearward wall portion, an alarm circuit within the building, and a lever switch with a switch lever for operating the switch and electrical switch terminals connecting the switch within the alarm circuit, the switch lever extending within the bolt receiving housing, where the housing is sized in depth relative to the throw of the bolt so that when the bolt is fully extended from the bolt assembly, the bolt extends into the housing to an extent that the bolt is positioned laterally adjacent to the switch lever, so that when the closure panel is moved toward an open position, such movement drives the bolt laterally against the switch

Abstract: A two-dimensional array of magnetomechanical markers is adhered to a continuous web. A magnetizer element is scanned across the web to magnetize the bias elements in a group of the markers with a first polarity, thereby activating the group of markers. The web is then advanced and the magnetizer is scanned across the web in an opposite direction to the previous scan, to magnetize the bias elements of a second group of the markers with a second polarity, thereby activating the second group of markers. The web is slit in a longitudinal direction to produce web-strips each carrying a column of the activated markers. The web-strips are rolled to form marker roll assemblies each having about half the bias elements magnetized with a first polarity and the remaining bias elements magnetized with an opposite polarity. The roll of activated markers forms no more than a minimal "leakage" magnetic field.

The device senses unauthorized movement of one or several elements in the lock and causes an alarm signal which may only be terminated by resetting the device by authorized operation of the lock.

Abstract: A system for synchronizing a seismic system having multiple subsystems. A control system transmits a message to selected subsystems and an internal subsystem counter is zeroed to a selected epoch. Depending on the message or on an internal instruction code, each subsystem initiates an event or sequence of events synchronized to the selected epoch. The system is based on the relative occurrence of cyclic events and does not depend on the transmission of an absolute time signal. The system is self rectifying, reduces systemic errors, and reduces the data transmission required for system control and operation. The system permits autonomous, asynchronous operation by a subsystem without continuous control by a central controller as a function of time, and can interactively respond to events without intervention from the central controller.

Abstract: An electrical lead has a first set of terminals (14) at one end of the lead and a second set of terminals (15) at the other end of the lead. A connector circuit (11,12) respectively connects the terminals (14) to the terminals (15). This circuit (11,12) is adjustable so as to change the connection paths between the first and second sets of terminals (14,15). The connector circuit (11,12) is surrounded by a security enclosure which comprises flexible sheet means of electrically insulating material carrying an array of lines of electrically security conductors. Monitoring means are connected to the security conductors to detect a change in an electrical characteristic thereof resulting from damage to the security enclosure. The invention can be used in a financial terminal, and provides security against a fraudulent attack on the lead intended to gain access to confidential information, such as a personal identification number, transmitted over the lead.

Abstract: A rolling truck consisting of a metal container on whose bottom are provided castors and at least one brake gear, where the bottom has a contact area between the castors on the opposite sides for placing the rolling truck on a conveyor belt. A transponder is arranged on the bottom of the rolling truck, and the transponder is mounted on a plastic spacer at a distance from the bottom of the rolling truck, and outside the contact area of the bottom of the rolling truck. This reduces the distance between the transponder and the floor where the antenna of an RF reader is installed, and thus reduces the size and power required for the transponder.

Abstract: Electric fences used to keep animals in or out of a particular area of land often cover great distances over all manner of terrain, making it very difficult to ensure the effectiveness of the entire length of the fence, especially at points distant from a human supervisor or at points which are not in a direct line of sight from a human supervisor. This invention relates to an electric fence monitoring system having a centrally located monitor and one or more remote units positioned along the fence, where the monitor uses wireless communication to broadcast a request for information related to one or more electrical conditions of the electric fence and the remote unit receives the request, takes a reading and uses wireless communication to broadcast a data message back to the monitor via wireless communication.

Abstract: A method and apparatus for detecting drowsiness and awakening the user. The load on a piezo-ceramic eye blinking detection unit changes upon blinking activity resulting in an electrical output. This electrical output is then processed and compared to a predetermined time interval for blinking. An alarm is sounded if the processed electrical output is less than the predetermined time interval.

Abstract: A security tag having a strap for securing the tag to an object to be protected and an electronic module connected to the strap for detecting an attempt to defeat the tag by short circuiting and severing the strap. The strap is formed of plural discrete conductors connected to the electronic module, which conductors are insulated from each other at least along a substantial length of the strap. Short circuiting of opposite ends of a single pair of the conductors followed by severance of plural ones of the insulated conductors, or short circuit in between separate conductors can be detected by the electronic module as an alarm condition. Severance or misconnection of only one or a small number of the insulated conductors can be detected by the electronic module as not being an alarm condition.

Abstract: A controlling interface unit is linked to a plurality of event sensors associated with a premises. There is at least one manner of establishing communication, using wired communication lines or radio transmissions between this interface unit and, on the one hand, a remote alarm receiving center for monitoring the sensors at the premises, and, on the other hand, a remote auxiliary facility for filtering out potential false alarms from those premises. The interface unit is capable of routing signals originating from a selected type of sensor to the auxiliary filtering facility instead of or in addition to transmitting the same signals to the alarm receiving center. Depending on the circumstances, feedback signals may then be transmitted from the auxiliary filtering facility to the controlling interface unit to negate an alarm condition. Optionally, a memory unit may be linked to the controlling interface unit to store data from the event sensors for a limited time period.
