  • Patent number: 7076403
    Abstract: An apparatus and a method for receiving and processing noisy communications signals automatically varies multiple processing parameters to both improve signal-to-noise ratio and to minimize delays in responding to changes in the incoming signal. The signal-to-noise ratio is improved with relatively stable signals by increasing the number of samples used in forming a processed signal value. In response to changes in signal input, the number of samples used in processing is substantially decreased while the sampling rate is substantially increased until the incoming signal exhibits an increased degree of stability. As the incoming signal becomes more stable, the number of samples used in performing a processed signal value is increased toward maximum and the sample rate is decreased.

  • Patent number: 7068177
    Abstract: Multiple parameter fire detection uses outputs from one or more radiant energy sensors in combination with outputs from smoke or thermal sensors to shorten response times to alarm while minimizing nuisance alarms. The radiant energy related outputs can be used to alter parameters of the smoke or thermal sensors. The various sensors can be displaced from one another in an alarm system.

  • Patent number: 7034304
    Abstract: A gas sensor, which could be a sensor of combustible gases, incorporates a diffusion chamber having symmetrical sensing and reference portions. A common source emits infrared-type radiant energy symmetrically into the two portions. Each portion incorporates a curved reflective surface which reflects incident infrared onto a respective sensor. Each sensor has a filter which passes a different selected band of energy. A fluid, such as gas being sensed, passes laterally through the chamber.

  • Patent number: 6987459
    Abstract: A portable detector of combustible or explosive gases incorporates a polymeric-type sensor or sensor array coupled to a programmed processor which carries out an evaluation of one or more signals from the sensor or array to evaluate the presence of combustible or explosive vapors. Non-polymeric sensors such as temperature sensors, humidity sensors and/or pressure sensors can also be incorporated and their outputs evaluated to compensate the outputs of the sensor or array of sensors. The detector can be housed in a sealed enclosure and energized by a battery.

  • Patent number: 6498563
    Abstract: A communication protocol facilitates transmission at maximum rates for various types of cables. Signal to noise characteristics are improved by using voltage waveforms. The protocol can be used to transmit information between a common control unit and a plurality of spaced apart devices coupled thereto. Alternately, the protocol can be used for transmission of information between devices. The common control unit transmits clock pulses, while in a low impedance state. The devices respond to the clock pulses and transmit data on the communications link, in a low impedance state, when the common control unit has assumed a high impedance state. Clock signals and data signals are separated to improve signal to noise characteristics by transmitting same with opposite polarities. A clock detection circuit responds to the polarity of the clock pulses. A data detection circuit responds to the polarity of the data pulses.

  • Publication number: 20020118116
    Abstract: A dual sensor detector incorporates a fire sensor, such as a smoke or heat sensor, and a gas sensor. Control circuitry is coupled to the sensors. In response to a sensed fire condition, such as due to heat or smoke, a constant sample rate sampling parameter, such as a sample time interval or a drive amplitude, is increased for the second sensor so as to increase its signal-to-noise ratio and resolution. The second sensor will be operated with the increased sample interval or drive amplitude so long as the first sensor continues to exhibit the detection of a condition. When the first sensor drops outs of the detection of a condition, the alterable parameter of the second sensor is reset to its quiescent state which draws a lower current value.

  • Patent number: 6392536
    Abstract: A multi-function detector has at least two different sensors coupled to a control circuit. In a normal operating mode the control circuit, which could include a programmed processor, processes outputs from both sensors to evaluate if a predetermined condition is present in the environment adjacent to the detector. In this mode the detector exhibits a predetermined sensitivity. In response to a failure of one of the sensors, the control circuit processes the output of the remaining operational sensor or sensors so that the detector will continue to evaluate the condition of the environment with substantially the same sensitivity.

  • Patent number: 6366215
    Abstract: The members of a multi-processor communication system can be loaded with a common set of control programs. Subsequently, the functionality of the various processors can be specified by providing linking information to the respective processors.

  • Patent number: 6320501
    Abstract: A multi-unit ambient condition detecting system incorporates either a wired or a wireless communication medium wherein the units are in bi-directional communication with one another. Units can incorporate programmed processors and ambient condition sensors such as smoke or gas sensors. In response to detected local ambient conditions, the respective units can transmit messages indicative of the level of sensed ambient condition to other units in the system. The units can maintain running totals of levels of ambient conditions received from other units in the system and combine those received indicators, along with one or more locally generated indicators, to determine that a selected condition, such as fire or gas is present in at least a portion of the region being monitors. Output devices coupled to the communication medium can provide human discernable audible or visible indicators of the presence of one or more selected conditions.
