    摘要: A portable breath test simulator including a case having a jar support arm extending to one side of the top of the case. A jar containing a known water-alcohol solution is mounted on the bottom of the arm. The case and jar support the simulator. A magnetic power drive located in the case to one side of the jar rotates a magnetic stirrer in the jar. Breath blown into the jar forms an effluent having a known concentration of alcohol and is flowed to a breath test analyzer to be tested.

    摘要: Electrical supply current, sufficient to power a wireless access point, is transmitted concurrently with a network data signal across a transmission line. A power and data coupler couples the network data signal and the power signal, received through a data input and a power input respectively, and transmits the coupled signal, to a distance of three meters or more, over the transmission line to a power and data decoupler. The power and data decoupler separates the power signal from the network data signal and supplies those signals to a power output port and a data output port, respectively, for use by a wireless access node. The power signal may be modulated at a low frequency relative to the frequency of the data signal, and the network data signal has a data transmission rate of one megabit/second or higher.

    摘要: A micro-power, micro-size RF detector is suitable for implementation on an integrated circuit. The detector is used for detecting the presence of high frequency AC signals on a transmission line which has a transmission line impedance. An input for connection to the transmission line through a high impedance relative to the transmission line is provided. A current mode detector is coupled to the input. The current mode detector translates AC signals on the input to a bias signal having a DC component determined by power of the AC signal on the transmission line. A current mode amplifier is coupled to the current mode detector, and amplifies the bias signal to produce a detector current. A binary output driver is coupled to the current mode amplifier, which generates a binary signal having one binary level if the detector current exceeds a high signal threshold, and another binary level if the detector current falls below a low signal threshold.
