Abstract: RF attenuator circuitry includes an RF attenuator and a control system. The RF attenuator is configured to provide an attenuation response between an input node and an output node. The control system is coupled to the RF attenuator and configured to adjust one or more control signals provided to the RF attenuator based on either the temperature of the circuitry or an externally applied test signal provided to the control system. The control signals are provided such that the attenuation response of the RF attenuator is substantially linear-in-dB with respect to either the temperature or the test signal provided to the control system. Because the control system is configured to adjust the control signals based either on a temperature of the circuitry or the test signal, the response of the RF attenuator can be easily and quickly tested to ensure linear-in-dB operation thereof.

Abstract: An automatic sensor excitation voltage adjustment feature, a multi-range concentration feature, a single calibration feature and a barrier circuit feature. The automatic sensor excitation voltage adjustment feature includes a transmitter having a transmitter microprocessor that provides an initial voltage to a sensor having a sensor microprocessor. As the voltage changes a correction signal is relayed from the sensor microprocessor to the transmitter microprocessor. The correction signal is used to adjust the voltage applied to the sensor. The multi-range concentration sensor feature includes an amplifier associated with the sensor/microprocessor to create gain settings used to optimize sensor resolution by changing a gain value for the sensor. This enables use of a single sensor for a variety of different concentration ranges.

The processor is configured to interpolate between the stored data points of the plot to determine an interpolated data point corresponding to the intensity response of the sample gas. The processor provides to the user a concentration level of the sample gas, based on the interpolated data point.

Abstract: Unlike known wheel-speed sensors, the wheel-speed sensor in accordance with the present invention is readily serviceable without disassembly of major components of the wheel assemblies and is relatively simple, and thus less expensive to manufacture, than known wheel-speed sensors. Two embodiments of the wheel-speed sensor in accordance with the present invention are disclosed. One embodiment relates to a “between-the-rows” wheel-speed sensor which includes a magnetic exciter ring that is adapted to be affixed to a rotating axle between rolling element rows of a wheel bearing. In an alternate embodiment of the invention, the wheel-speed sensor is configured to form a grease seal which typically inserts into the end of an axle tube. A wheel-speed sensor utilizes a multiple pole magnetic exciter ring that is adapted to be attached to a rotating axle shaft. The wheel-speed sensor includes a two-piece stator which also functions as a grease seal which concentrates flux from a rotating multiple pole exciter ring.
