Abstract: A self-contained monitor including a volatile memory circuit having an armed and a disarmed state, a nonvolatile memory circuit, a responder and an intrusion detector is disposed in a predetermined space to sense and report an intrusion therein. A primary power source having momentary and sustained power interruptions associated therewith energizes the self-contained monitor. A short term energy storage circuit provides secondary power to the volatile memory circuit communicating therewith and with the primary power source so that momentary power interruptions do not result in the volatile memory circuit sensing a loss of power. The volatile memory circuit is switched from the armed to the disarmed state by either the sensing of the intrusion or by the sensing of at least one sustained power interruption. A user employs a remote controller to transmit an RF test signal to remotely test the state of the volatile memory circuit.

Abstract: An intrusion detection system used to surveil a predetermined space includes a monitor disposed within the space and a remote controller. The monitor comprises an intrusion detector for sensing an intruder in the space and a memory circuit having an armed and a disarmed state recording any sensed intrusion. The remote controller includes an RF transmitter activated by a button switch the pulsed closure of which either arms or tests or disarms the monitor. When arming the monitor, a first audible or visual output is produced by the monitor in response to the RF pulse which switches it from the disarmed to the armed state. In the armed state, the monitor produces a second audible or visual output in response to the RF pulse which is used to test the state of the monitor. The second response is easily distinguished from the first response by a user. If an intrusion occurs, the monitor produces an alarm signal.

Abstract: A condition handling method and means capable of handling programs written in a plurality computer programming languages is created by a set of routines which implement the Common Condition Handling (CCH) function. These routines have entry points which are declared as external or entry variables which enables application programs to link to them. The compilers and application programs can then interact with the condition handling process by calling or branching to the entry points in the common condition handling code when the program is executing. Language specific condition handling routines and user condition handlers are invoked using a last-in-first-out (LIFO) queue to associate the handlers with the current stack frame. Any handler may respond to the CCH with one of three types of requests: Resume, Percolate, and Promote. A separate means is provided for registering Exit Handlers and to move the resume cursor.

Abstract: An intrusion detection system used to surveil a predetermined space includes a monitor disposed within the space and a remote controller. The monitor contains an intrusion detector for sensing an intruder in the space and a memory circuit for recording any sensed intrusion. The remote controller includes an RF transmitter activated by a button switch the timed closure of which arms the monitor and the pulsed closure of which tests the monitor. The monitor produces an audible or a visual output in response to a test RF signal transmitted by the remote controller to indicate that an intrusion has not occurred. A pulsed closure of the button switch while the monitor is producing the output disarms the monitor. Should the monitor detect an intrusion and/or be disabled by the intruder, the lack of the monitor output in response to the test RF signal transmitted by the remote controller warns a returning occupant, before entering his or her premises, there exists the possibility of confronting an intruder.
