Abstract: A vehicle battery electrical system tester with a hand-held remote control can include a vehicle battery electrical system tester with a radio frequency transceiver and a remote control unit with a radio frequency transceiver. Preferably, the vehicle battery electrical system tester and the remote control unit both include a radio frequency integrated circuit transceiver microchip. In addition, each can include a microcontroller coupled to the transceiver to control the transceiver. Furthermore, each can include an antenna, preferably an integrated circuit antenna. The remote control unit can include a visual display device, such as an LCD display, and an input device, such as a keypad.

Abstract: An apparatus and method for data communication is provided to use with existing or future scan tool. The apparatus is an adapter that couples with the scan tool and a communication network interface on a vehicle. The adapter allows CAN communication or other communication protocols between the scan tool and the communication network interface on a vehicle and provides a good alternative to buying a new scan tool.

Abstract: A device and method for determining the status of an anti-lock brake system in a tractor-trailer configuration. The device includes a connector that can be connected to the trailer or tractor separately or connected to both the trailer and tractor simultaneously. Once connected the device begins to operate self-sufficiently by monitoring the data transmissions in a communication medium. Initially from monitoring the data transmission, the device detects whether it is attached to the trailer, tractor or both. From this determination, it either continues to monitor or proceeds to transmit data.

Abstract: A system comprised of a computer that contains a display device such as monitor, an input device (e.g. a keyboard or a touch screen), a storage device such as a hard-drive, and software capable of collecting data. The data is collected from an adapter of which one end is attached to the computer and the other one end and attached to an automotive part. The automotive part is tested and performance data extracted. The data is sent to a remote location or to the computer where it is compiled for a wire variety of uses.

Abstract: An engine analyzer for an internal combustion engine includes an analog-to-digital (A/D) converter which digitizes an analog input waveform representing, for example, a secondary or primary voltage waveform of the ignition coil of the internal combustion engine. The sampling rate of the analog digital converter is determined by dividing the waveform time period by the desired number of samples. An adjustment factor C is used to provide a buffer period during the sampling period of the waveform. A display for displaying the waveform has a buffer region which corresponds to the buffer period. Thus, a variation in the speed of the engine which causes the engine to slow down and extends the period of the engine waveform does not cause a loss of data collected from the waveform because the buffer period provides a margin of error.
