  • Patent number: 11080805
    Abstract: A computer-based method and apparatus for identifying hazardous materials based on observable physical properties and signs and systems of exposure to the hazardous materials. The observable physical properties are obtained by preprocessing plain language data to obtain normalized descriptors and modifiers pertaining to a plurality of properties and signs and symptoms. The normalized descriptors and signs and symptoms are presented to a user in lists for comparison with a sample in the field. Tightly integrated with identifying the hazardous materials are obtaining response data, obtaining controlled materials of which the hazardous materials may be precursors, and predicting reactions of pairs of hazardous materials. The preferred embodiments of the invention are particularly useful to responders to a hazardous waste incident.

The method comprises setting the motion detector to a calibration mode, waiting a preset period of time for the installer to walk to the furthest distance, receiving a Doppler signal generated by motion at the furthest distance from the microwave motion detector within the protected area, measuring an amplitude of the Doppler signal and storing a motion detection threshold for the microwave motion detector. The motion detection threshold is a proportional to the measured amplitude.

  • Publication number: 20100226408
    Abstract: A testing device for testing thermal detectors includes a hollow sleeve, open on at least one end, configured to receive a thermal detector. The hollow sleeve can have a length greater than a diameter. A heater is positioned is in proximity to the hollow sleeve, and is configured to provide heat for testing the thermal detector. The heater can be a flexible foil heater. A power source is provided to supply power to the heater. A power control module can be provided for variably adjusting a set point temperature or a rate of temperature rise for the heater.

  • Patent number: 7786855
    Abstract: Traffic induction loop simulator (LOOPSIM) software, and a system and method designed for traffic research and education. The system is able to generate output signals in response to previously recorded real traffic events or simulated traffic. If directly connected to a controller cabinet or a traffic event data collection system, LOOPSIM can be used to simulate output signals from loop detectors and to test algorithms executable in the controller, or to test the performance of a traffic data collection/monitoring system. LOOPSIM can simulate different predefined patterns of traffic distributions and replay loop event data recorded by a detector event data collection (DEDAC) system or an advanced loop event data analyzer (ALEDA) at a pace responsive to controller feedback. Using LOOPSIM, many traffic system tests can be conducted for multi-purpose traffic control applications, and traffic arrival patterns can be generated for researchers and educators to test theoretical models.

  • Patent number: 7652587
    Abstract: According to the method a temperature module is defined, simulating the thermal behavior in the electric motor (1), based on a multi-mass model. The rotational speed (n) and the current (i) for the electric motor (1) are continuously recorded as input parameters for the temperature model and at least one bearing power loss and/or bearing inner temperature (TIL1?), corresponding to a bearing (8,9), is continuously derived from the temperature model. A first warning signal (W1) is given when a computer-determined bearing power loss exceeds a given comparative value. Furthermore, a second warning signal (W2) is given when a computer-determined bearing inner ring temperature exceeds a given temperature difference (?T) from a corresponding computed bearing outer ring temperature (TAL1?). The thermal behavior of non-accessible components, in particular, the bearing (8, 9), can thus advantageously be determined by mere evaluation of the current (i) and the rotational speed (n).

  • Patent number: 7652566
    Abstract: Apparatus includes an arc wave generator for testing an arc fault circuit interrupter (AFCI) for use in a test system for testing whether or not an arc fault circuit interrupter (AFCI) is operating normally, in which a false arc is generated for use in testing the arc fault circuit interrupter (AFCI). The arc wave generator includes a rectifier which receives a commercial power source as an input source and rectifies alternating-current voltage of the commercial power source to generate a rectified signal. A drop resistor drops the voltage of the rectified signal to generate a voltage-dropped signal. A mono-stable multivibrator adjusts a voltage level and a pulse width of the voltage-dropped signal and generates a pulse signal which is used to generate a false arc for testing the arc fault circuit interrupter (AFCI). Thus, a false arc is generated with a simple circuit to accurately test the actions of the arc fault circuit interrupter (AFCI).

  • Patent number: 7639128
    Abstract: A method of operating a security system includes activating a security device and transmitting a first status report from the device in response to the activating step. A second status report is transmitted from the device after the first status report has been transmitted. The second status report is indicative of a status of an input of the security device. It is determined whether the first status report indicates a status different than the status indicated by the second status report. A third status report is transmitted from the device after the second status report has been transmitted. The third status report is indicative of the input of the security device being in an alarm condition and/or a trouble condition. Dependent upon whether the first status report indicates a status different than the status indicated by the second status report, an alarm and/or a trouble warning are issued in response to the third status report.

  • Patent number: 7636039
    Abstract: An apparatus and method are provided for a security device for residential and/or commercial buildings. A motion detector is installed on a fixture such as a wall or ceiling. A wireless remote is used after installation of the motion detector to set the motion detector to a walk test mode, eliminating the need for the installer to open up the motion detector to switch it to a walk test mode. After walk testing the motion detector, the wireless remote is used to set the motion detector back to a normal mode, eliminating the need for the installer to open up the motion detector and avoiding the problem of the installer forgetting to switch it back to a normal mode. The motion detector can also switch back to a normal mode after a predetermined amount of time by use of a timer.

  • Patent number: 7587926
    Abstract: An apparatus (10) for testing detectors has a cup or chamber (30) supported within a mid-cap (40) by a support ring (50). An adjustable cap (70) attaches at one end to a mid-cap (40) and at the other end to a step-adjust cap (80) via bayonet mounting. A handle (60) is pivotally connected to pivot pins (46) located on the mid-cap (40).
