Abstract: A programmable interface module includes a linear power regulator to control and provide power to interfaced components on an as needed basis. The interface module is implemented in, for example, a sensor pack and multiplexed to a plurality of sensor modules. In a first mode, the linear voltage regulator provides a relatively small amount of power which allows a sensor module to output a signal responsive to detecting an environmental condition (e.g., gamma or x-ray radiation, extreme temperatures, etc.). The interface module can switch the linear voltage regulator to a second mode in which the linear voltage regulator ramps up the amount of power provided to a detecting sensor module. The sensor module can then provide a level indicative of a concentration or intensity of the environmental condition. If the level surpasses a predetermined threshold, the sensor pack can output an alert signal to security server.

Abstract: A remote control system relating to a remote control and a base charger. A rechargeable battery contained within the remote control is charged when rested within a charging position of the base charger. Once a user removes the remote control from the charging position, the remote control doubles as a portable hazard detector that operates in a sustained manner for as long as the rechargeable batter has power. This means that the remote control will emit an alert noise if a hazard such as smoke or high level of carbon monoxide is detected by internal sensors located within the remote control. The base charger also has sensors and an alert speaker to inform the user of a potential hazard. In addition, the base charger is in communication with the remote control so that a user can locate a missing remote control.

Furthermore, a signal from the first light-receiving element and a signal from the second light-receiving element are amplified by an identical amplifier circuit. In a microcomputer, the density of smoke is computed based on a difference between an output obtained by amplifying an output of the first light-receiving element with the amplifier circuit and an output obtained by amplifying an output of the second light-receiving element with the amplifier circuit.

Abstract: A detection system in which a single sensor is employed to detect an extensive range of a parameter. The output signal from the sensor is fed to the input of the electrical circuit, having a feedback loop, wherein the electrical circuit has a non-linear transfer characteristic. The non-linear transfer characteristic is achieved by changing the behavior of the feedback loop of the electrical circuit at a predetermined level of input signal. The output of the circuit has a proportional relationship with the input until the input signal reaches this predetermined value, whereupon the behaviors of the feedback loop changes and the relationship of the output to the input of the circuit changes. While the input signal is above the predetermined value, the output of the circuit has a linear but disproportionate relationship with the input at a gradient different to that when the input signal is below the predetermined value.

The alert system includes a voice signal, such as “EXIT LOCATED HERE,” to signal that the location of the voice is also the location of the exit. A white noise signal generator is used to supplement the voice signal and produces a sound that is particularly localizable by the human ear. A strobe light and a laser are used to produce a visual guide to the location of the exit. The strobe light is flashed when the word “HERE” is used in the voice signal. The laser is used to produce a cone of light that points towards the fire exit alert system.
