Abstract: A tamper switch body is disposed in a housing of a PIR sensor. A tamper opening is formed at a position opposite a switch actuating member of the tamper switch body in a base plate of the PIR sensor. An elastic switch member is mounted in the tamper opening. The elastic switch member includes a pressure-receiving projection portion abutting a mounting plate, and depresses the switch actuating member through elastic deformation of the pressure-receiving projection portion by receiving a pushing force from the mounting plate in a state in which the PIR sensor is fixed to a wall surface. The elastic switch member seals the inside of the housing by closing the tamper opening, thus preventing a flood into the housing of the PIR sensor.

Abstract: A device for redirecting alarm-messaging from an alarm control panel from its connection to the PSTN to a backup radio transceiver for transmission of the alarm signaling to a central alarm station via a radio network. The switch-over to the radio network occurs not only when the PSTN line is down, for whatever reason, but also occurs when the PSTN line is already occupied by an existing transmission by a premises' telephones, in order to allow the user to make a call over the PSTN during such an alarm condition. Moreover, if during the time the alarm control panel is transmitting its alarm messages over the PSTN, a premises' telephone goes off-hook, the device of the invention terminates the alarm panel's connection to the PSTN and automatically switches over the alarm panel to the radio backup system.

Abstract: An automatic door system capable of distinguishing between a door closing action for when an object leaves a prescribed area, which results from a “signal discontinuation due to the exit of an object”, and a door closing action for when an object remains stationary within the area for a certain period of time, which results from a “forced signal discontinuation in the presence of a stationary object”. Regarding the latter case, the automatic door system protects a person who stops in the area by setting the door to close at a low speed and/or issuing a vocal warning. The door closing action of the automatic door system can thereby reduce the risk of hitting the person with the door.

Abstract: A system and process that computes the probability of histogram matching false alarms for different settings of a histogram matching algorithm's parameters is presented. This allows the parameters to be adjusted to produce the optimum object finding capability with the lowest possible false alarm rate. Generally, a prototype histogram is generated from a model of an item being sought in an environment. The set of all possible test histograms that can be formed from the environment given a prescribed number of bins and a maximum count for the bins is then determined. Once this is accomplished a subset of test histograms from the set of all possible test histograms which will cause a false alarm is found. Then the probability of occurrence of each individual test histogram that will cause a false alarm in the subset is determined and summed to establish the overall false alarm probability.

Abstract: An apparatus and method therefor wherein instead of applying a high bias voltage 100 per cent of the time to leads susceptible to dendrite formation, the bias voltage is switched from a low bias voltage to a high voltage bias mode when the leads (19) are to be read or scanned by a microprocessor (14), and the bias voltage is then switched back to a low bias voltage mode when the lines are not being read, e.g., at other times, thereby greatly reducing the high bias “on” time and dramatically reducing the probability of dendrite formation. The reduction of high bias voltage “on” time is accomplished by programming the microprocessor (14) to switch the applicable input ports (16) to be output ports when the leads (19) are not to be read. As output ports, the output impedance and output voltage of the microprocessor are low as opposed to a high input impedance when the terminals are input terminals.

Abstract: A system for sensing ambient conditions in a compartment, such as the trunk of an automobile, generates a control signal in response to the sensed conditions. This control signal actuates indicators to notify operators of the vehicle that there is a person trapped in the trunk. The control signal is also used to actuate a lamp inside the trunk to provide light for the trapped person. A trunk release is also actuated, by a control module, to free the trapped person. The trunk release of the automobile can be prevented from being actuated if the automobile is moving, which prevents the trunk lid from unexpectedly opening while the vehicle is in motion.

Abstract: A wireless intrusion detector that contains a test mode that temporarily overrides the normal inhibit function of the wireless intrusion detector allowing all alarm messages to be transmitted. Wherein the inhibit function lets a single detected event signal to be transmitted upon the detection of an alarm event and inhibits subsequent transmissions during a predetermined inhibit period. The test mode, usually entered after installation of the intrusion detector, is automatically entered when the case of the intrusion detector is closed and is automatically exited when a predetermined number of detected events have been detected by the detector. The duration of the test mode is dependent on the detection of motion a predetermined number of times rather than a predetermined time duration. This allows the installer to perform a complex and time consuming walk test without having to open and close the detector case a number of times.
