    Abstract: A system and method for monitoring and safety related systems (SRSs) in a Secure Compartmented Information Facility (SCIF) that addresses concerns for security of electronic emanations from equipment in the SCIF. A fiber optic link connects an optical receiver located within a SCIF and an optical transmitter located outside the SCIF. Alarm signals generated by an SRS located outside the SCIF are detected and sent to the optical receiver over the fiber optic link. The optical receiver converts the optical signals to electrical signals and directs the signals to alarm devices within the SCIF. Additionally, an audio signal generated at the location outside the SCIF is converted to an optical signal and then reconverted to an audio signal by the optical receiver for broadcast over a speaker located within the SCIF. A tone signal generated at the optical transmitter is continuously sent over the optical fiber link to the optical receiver and the SCIF speaker.

  • Patent number: 6518879
    Abstract: A fire alarm apparatus, for checking line disconnection or occurrence of a fire, regardless of the installation place of a terminal endpoint resistor installed for checking disconnection of a line of fire detectors. When a signal representing a present voltage state of the detectors is input through the line, a control section compares the voltage level of the signal with a reference voltage level, and generates either a line disconnection control signal or a fire control signal. A first alarm section provides indication of disconnection of the line in response to the line disconnection control signal and a second alarm section provides indication of the occurrence of fire in response to the fire control signal. The apparatus can thus monitor a state of the detecting line, the common line and the fire detectors, regardless of the installation place of the terminal endpoint resistor.

  • Patent number: 6452492
    Abstract: An alert system for providing an alert of an actual or impending emergency to homes, businesses and the like. The alert system is used in cable system network over which communication signals are transmitted to a receiver remote from the transmitter. Such communication signals have associated therewith at least one distinguishable modulation frequency. The alert system includes a mechanism for receiving an alert request and a transmitter for transmitting an alert signal in response to the alert request. The transmitter is coupled with the cable system and generates an alert signal which is modulated at a frequency distinguishable from the frequencies of the communication signals. The transmitter includes a sideband filter to reduce the subharmonics generated around the alert signal frequency. The receiver includes a mechanism for detecting a valid alert signal from the alert signal received and for generating an alarm signal therefrom.

  • Patent number: 6452493
    Abstract: A process control instruments includes a sensor for sensing a process variable in a processing environment, and a switch, a gauge, and a transmitter. The sensor, switch, gauge, and transmitter, a controller to which each of the stated and related components are connected, are powered via a two-wire power loop. In particular, the two-wired power loop also comprises the transmitter, such that the controller, upon receiving information indicative of the level of a variable being sensed by the sensor, modulates the amplitude of the current on the two-wire loop to a level corresponding to the level of the processed variables sensed. Each of the switch, gauge, and transmitter are independently scalable. In the preferred embodiment of the invention, a pair of switches in the form of relays are provided, and a logic circuit operates to power the components of the invention, with the exception of the relays, when the process variable being sensed with within a selected range.

  • Patent number: 6445291
    Abstract: A security system comprising a plurality of remote wireless units, a central control unit and an adaptive console for translating messages in radio frequency signals into messages in signals suitable for transmission over a wire in order to augment the wireless capability of the system. The adaptive console has a wireless receiver for receiving the radio frequency signal, which includes identification and status information from a wireless remote units. The adaptive console also has a processing unit which translates the identification and status information from the radio frequency signal to corresponding function data derived from a mapping of valid identification and status information to function data, the function data representative of a function to be performed by the security system. The adaptive console also has a transmitter which transmits a signal over a wired connection which includes the corresponding function data to the central control unit or a wired security unit.

  • Patent number: 6392534
    Abstract: A vehicle control system includes a data communications bus; at least one vehicle device being selectively operable by a user to generate signals on the data communications bus; and a controller, such as a security controller, connected to a receiver and being responsive to a remote transmitter. The controller is also preferably switchable to a desired mode from among a plurality of modes based upon signals generated on the bus by selective operation of the at least one vehicle device by the user. The controller may be an aftermarket security controller that is very easily added to the vehicle and uses an existing vehicle device to switch between modes, without requiring the installation of one or more hardwired and dedicated switches, for example. The at least one vehicle device may comprise at least one desired vehicle switch for also controlling a vehicle operation other than switching the security controller.

  • Patent number: 6346876
    Abstract: A control system includes a transmitter and a receiver for receiving signals from the remote transmitter, and a multi-vehicle compatible controller cooperating with the transmitter and receiver. The multi-vehicle compatible controller preferably generates at least one set of command signals on the data communications bus for the at least one vehicle device. The at least one set of command signals may include at least one working command signal and at least one non-working command signal for a given vehicle to thereby provide compatibility with a plurality of different vehicles. Multiple signals or codes can be generated on the data communications bus, and only that code for the given vehicle will cause an operation or response from the vehicle device. Such an arrangement provides for a relatively simple and straightforward approach to interface with a vehicle having a data communications bus.

  • Patent number: 6342834
    Abstract: A personal security system locates emergency transmissions and tracks changes in location between successive transmissions. The transmissions are repeated automatically over a predetermined time interval exceeding five minutes. A plurality of fixed receivers are provided in predetermined positions in a protected region for detecting the emergency transmissions and a central monitoring station locates the transmissions from information provided by the detecting receivers. The monitoring station tracks successive transmissions and displays multiple locations as icons on a monitor. The icons vary in size based on relative transmission time and are stacked so any overlapping icons representing more recent transmissions are on top.
