Embodiment Construction

[0021] For purposes of illustration, the following description discloses various exemplary embodiments of a vehicle servicing device / system powered by a capacitive power storage unit. It will be apparent, however, to one skilled in the art that the inventive concept may be practiced or carried out without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.

[0022] figure 1 An exemplary Wireless Location System 10 embodying the concepts of the present invention is shown. Wheel alignment heads 13 (front left), 14 (rear left), 16 (rear right) and 17 (front right) were detachably mounted to the vehicle wheels under test, and at least one alignment head was powered by a capacitive power storage unit. These alignment heads are used to measure different angles of the vehicle's wheels and / or suspension, such as toe, caster and camber. Infrared transmitters and...

Abstract

A vehicle service device configured to be powered by a capacitive power source positioned in the service device.

Description

technical field [0001] The present invention relates to vehicle maintenance devices and systems powered by capacitive power supplies. Background technique [0002] In order to eliminate the need for electrical cords to draw power from electrical outlets, many vehicle maintenance systems or devices, such as vehicle diagnostic systems, location systems, etc., are powered by disposable or rechargeable batteries. Elimination of wires provides for easier system setup and a less obstructive work environment. [0003] However, the use of batteries to power vehicle maintenance devices and systems has several drawbacks. Rechargeable batteries only have a useful life of a few hundred charge and discharge cycles. The cost of replacing batteries is high. In addition, the disposal of used batteries poses an environmental hazard and thus requires special and sometimes costly disposal processes or facilities. Additionally, it often takes hours to fully charge the battery before it can ...
