    摘要: Presented is a communications protocol for use by interconnected hazardous condition detectors, such as smoke and carbon monoxide detectors for use in dwellings and other structures. This communications protocol provides conventional signaling to indicate the presence of a smoke condition necessitating the generation of a smoke temporal pattern by all interconnected detectors. The protocol further defines a signaling method by which conventional smoke detectors that are incapable of providing temporal patterns other than that required for a smoke alarm condition will not be sent into an alarm mode of operation upon receipt of a signal other than the conventional smoke alarm signal. This communications protocol defines a pulsed signal to indicate a non-smoke alarm condition that is of a duration that will not trigger the conventional smoke alarms. To allow for the transmission of multiple hazardous conditions alarm notifications, as well as the transmission of additional hazardous condition detector control signals, the communications protocol utilizes a multi-bit signal transmitted via the conventional single signal I/O wire of currently existing interconnect wiring. Through the use of an 8 bit alarm signal, multiple hazardous conditions may be signaled as well as operating modes such as test, hush, reset, low battery, etc. Also presented are smoke, carbon monoxide, and combination hazardous condition detectors that utilize the communications protocol presented herein.

    摘要: A microcontroller supervision circuit comprising an electronic control capable of causing a high-impedance on at least one external pin upon occurrence of a reset condition. A supervision circuit is coupled to the at least one external pin for detecting the high-impedance condition. Upon detection of the high-impedance condition, a signal is generated to indicate failure of the microcontroller to execute code. The microcontroller is programmed to remove the high-impedance condition when code is properly executed within the microcontroller.

    摘要: An apparatus for the detection and enunciation of hazardous conditions within an environment comprises at least two detection circuits positioned to sense ambient conditions within a home or business environment. One of the detection circuits senses the presence of smoke, and the other detection circuit senses the presence of carbon monoxide. The apparatus also comprises an alarm circuit which is responsive to each of the detection circuits for generating at least one alarm pattern, and preferably a separate alarm pattern for each different sensed condition. A voice synthesizer circuit is also included, and is responsive to each of the detection circuits for generating at least one voice message. As with the alarm patterns, the voice synthesizer preferably generates separate voice messages for each separate detected condition. The apparatus advantageously also contains an interleaving control circuit. This interleaving control circuit interleaves the alarm patterns and voice messages in a predetermined sequence to reduce confusion in an emergency situation. A method for the detection and enunciation of multiple hazardous condition within an environment is also presented, and comprises the steps of: (a) sensing ambient conditions within the environment to detect at least two hazardous condition; (b) generating an alarm pattern and a voice message in response to sensing the hazardous conditions; (c) interleaving the alarm pattern and the voice message; and (e) enunciating these interleaved alarm patterns and voice.

    摘要: A termination control circuit is coupled to a far end of a cable. A modulated test signal is reflected back to a near end of the cable at a different frequency but at substantially the same level of attenuation as the test signal. Signal attenuation in the reflected signal is then measured to determine the amount of attenuation in the test signal. A second embodiment of the termination control circuit measures crosstalk by enabling and disabling termination resistors at the far end of the cable. A DC bias voltage located at the near end of the cable selectively turns on switching diodes to enable the termination resistor. Alternatively, both the attenuation and crosstalk circuits are combined together allowing both signal attenuation and crosstalk measurements with the same termination control circuit.

    摘要: A time-domain reflectometry device and method are provided wherein TDR may be performed on active Ethernet systems. A crossover network provides proper impedance termination both for pulse information generated by the TDR and for DC path signals. If a potential collision is detected when generating TDR pulses, a collision is forced by asserting a DC bias on the network thereby simulating a collision and generating a timeout at a much lower protocol level for reducing noticeable delay to network users and increasing network throughput.

    摘要: Disclosed is a system that monitors the signal strength of each transmission by a node on a LAN cable of a local area network and determines the location of the node sending the signal. This system has a monitor at each end of the LAN cable, with one of the monitors typically being located in a computer node attached to the cable. When an information frame is sent on the cable, each of the monitors records the signal strength of the frame preamble and the source address contained within the frame. The distance to the node from a first end of the cable, expressed as a percentage of the length of the cable, is the ratio of the signal strength at the second end of the cable to the sum of the signal strengths.
