Abstract: A system for calibrating signals received over a power line within a vehicle includes a signal conditioning circuit that converts the analog input signals into digital input signals. In one embodiment the circuit includes an adjustable gain circuit that outputs an amplifier gain signal establishing an amplifier gain level and an amplifier that outputs amplified signals responsive to the analog input signals and the amplifier gain signal. In another embodiment, the circuit includes a bias circuit that outputs a bias signal establishing a bias level and a comparator that generates the digital input signals responsive to the analog input signals and the bias signal. A controller receives the digital input signals and generates, depending on the embodiment, one or more control signals configured to control the configuration of the amplifier gain signal and amplifier gain level and/or the bias signal and the bias level.

Abstract: A system for transmitting and receiving signals having varying frequencies along a power line within a vehicle is provided. A transceiver is configured to transmit output signals to and receive input signals from various electronic systems on a vehicle along a power line at a first frequency. A frequency control circuit determines whether the destination system for the output signal is configured to receive the output signal at the first frequency or a different frequency and modulates the frequency of the output signal if necessary. The frequency control circuit also determines, prior to receipt by the transceiver, whether the input signal has the first frequency or different frequency and modulates the frequency of the input signal if necessary.

Abstract: A tamper detection system for a controller includes a housing, a circuit board mounted in the housing, a voltage input line on the circuit board receiving an operating voltage, a light detection circuit mounted on the circuit board receiving the operating voltage from the voltage input line and a signal conditioning device conditioning the operating voltage and connected to the light detection circuit. The light detection circuit interrupts the operating voltage at the signal conditioning device in response to detecting a source of light having a light value greater than a threshold.

Abstract: A system for demodulating and decoding received messages transmitted along a vehicle power line includes a reference signal generator, a timer, and a demodulation and decoding circuit. The circuit determines whether a message is present on the power line by identifying a symbol indicative of a message preamble, subsequently setting the timer to a time corresponding to a predetermined length of the message preamble, detecting, during the time, a plurality of symbols and determining whether the symbols indicate the presence of a message preamble. The circuit then extracts data from the message by activating the reference signal generator, adding the reference signal to the message to produce an equivalent signal, detecting a symbol in the equivalent signal indicative of the message data body, subsequently setting the timer to a time corresponding to a predetermined length of the message data body and detecting, during the time, a second plurality of symbols.

Abstract: A system and method are disclosed for power line communication (PLC) signal data body encoding using differential phase detection. In one embodiment, if a preamble section of the PLC signal is too noisy, instead of attempting to read the actual signal in a data section of the PLC signal, a differential phase detection circuit is used to detect a phase difference between two symbols in the data section, as phase detection is less susceptible to noise.

Abstract: A system for controlling a plurality of sensors includes a plurality of filters each of which is configured to provide power transmitted at distinct frequencies to a corresponding sensor of the plurality of sensors to thereby active the corresponding sensor and cause the corresponding sensor to generate a data signal. A power frequency controller is configured to adjust a frequency of power from a power source and to transmit power at distinct frequencies at different points in time in order to activate each of the plurality of sensors at different times. A sensor controller may be configured to receive the data signal from each of the sensors over a common conductor and on a common pin and may also act as the power source providing the power to the power frequency controller.
