摘要:
The present invention relates generally to an automotive diagnostic tool which facilitates data communications between an automobile and diagnostic device, such as a personal computer. More particularly, the present invention relates to electrically isolating the data communications using a Vehicle Communication Interface (VCI) device situated between an automobile's communication diagnostic port and the personal computer. The VCI contains logic circuitry to translate the automobile's On Board Diagnostic (OBD II) signals to an embedded Ethernet controller. Ethernet signals are then non-galvanicly exchanged with an Ethernet to USB controller with an Ethernet transformer. A personal computer is attached via a USB cable to the VCI's Ethernet to USB Controller, permitting information exchange between the automobile and the personal computer.

摘要:
A vehicular diagnostic tool configured to interface with a plurality of vehicular computing systems that each utilize a different communications protocol. The tool includes a transceiver that itself includes a voltage threshold controller and a current threshold controller. Also, a method of using a single vehicular diagnostic tool to communicate with a plurality of vehicular computing systems that each utilize a different communications protocol.

摘要:
A method and apparatus for automatically sensing the temperature of a battery during the testing and charging. The method and apparatus can monitor the temperature of the battery, the charger or both. Additionally, a user can be notified when the temperature is at or exceeds a predetermined level. The temperature data is also used to aid in efficiently charging the battery.
摘要:
A method and apparatus for communicating a battery information to a remote device or database. The battery tester and/or charger can communicate with a wired or wireless connection to the remote device. Battery indentifying information, test results and warranty information can be communicated to the remote device or database.
摘要:
A method and apparatus that allows a battery charger/tester to store and retrieve information from a storage media. Information, such as the result of the charge and testing of the battery, can be stored on the storage media. Additionally, information, such as firmware updates, can be uploaded from the storage media.

摘要:
A method and apparatus that allows a battery charger/tester to transmit and receive information from a remote location. Information, such as the result of the charge and testing of the battery, can be relayed via a wire or wirelessly to a remote device, such as a server for storage. Additionally, information such as firmware updates can be relayed to the battery charger/tester for upload.
摘要:
An engine starter motor tester applies power to a motor under test at the level normally applied while that motor is installed in a vehicle and monitors the ripple in the driving current. The ripple rate, scaled by the number of windings used in the construction of the motor, provides a direct reading of the shaft speed of the unloaded motor. This number allows a valid inference concerning the state of health of the motor, and is more certain than an estimate for an unloaded motor based on operator experience and motor “sound”. A complete test apparatus includes a stored lookup table, allowing the user to key in a product brand and model number and read directly both the RPM and the test apparatus's rating of the motor under test, expressed in terms such as percentage of life remaining.
