Abstract: A vehicle diagnostic display unit including a case, a display screen disposed within a front portion of the case, and a main support coupled to a side of the case and having a finger compartment for receiving a user's fingers to allow the user to lift the vehicle diagnostic display unit using one hand. A navigation pad is disposed on a front surface of the main support and the main support is configured to allow a user to simultaneously lift the diagnostic display unit and access the navigation pad with a thumb. The display unit also includes a combination folding stand and hanger assembly that allows the unit to be stood up for display, or hung for display, in a hands-free manner, such that a user is free to use both hands for other purposes while still being able to view the display screen.

Abstract: A detachable protection system for protecting a data processing system under rough operation environment. The system includes a housing having a surface for supporting the data processing system, a securing device, disposed on the housing, configured to detachably secure the data processing system when the data processing system is supported by the surface, and a handgrip device disposed on each of two opposite sides of the housing.

Abstract: A interface device for powering a data processing system using an output of a vehicle diagnostic port, such as an OBD II connector, that outputs self-diagnostic information. The vehicle diagnostic port is disposed on, and an integral part of, a vehicle. The interface device includes a first connector, a second connector and a power converter. The first connector is configured to detachably couple to the vehicle diagnostic port to receive output signals therefrom. The output signals of the vehicle diagnostic port include a vehicle power output and a diagnostic output including self-diagnostic information. The second connector is configured to detachably couple to a docking connector of the data processing system. The power converter, coupled to the first connector and the second connector, is configured to generate a regulated voltage based on the vehicle power output of the vehicle diagnostic port. The regulated voltage is provided to power the data processing system.

Abstract: A vehicle diagnostic display unit including a case, a display screen disposed within a front portion of the case, and a main support coupled to a side of the case for allowing a user to lift the vehicle diagnostic display unit with one hand. A navigation pad is disposed on a front surface of the main support, and the main support is configured to allow the user to simultaneously lift the diagnostic display unit and access the navigation pad with a thumb. The display unit also includes a user-replaceable, transparent protective cover that attaches to the front portion of the case over the display screen. The display unit and the protective cover include novel features that allow the protective cover to be replaced by a user without having to return the display unit to the manufacturer.

Abstract: A vehicle diagnostic display unit is provided for performing diagnostic procedures on a vehicle using only one hand. The vehicle diagnostic display unit includes a case, a display screen, a main support, and a plurality of keys. The case has a front portion, a rear portion, a top portion, and a bottom portion. The display screen is disposed within the front portion, and the main support is coupled to a side of the case. The main support is configured such that a user can simultaneously lift and operate the diagnostic display unit with a single hand.

Abstract: A system for obtaining positional information about a vehicle includes a vision imaging system and a vehicle position adjustment mechanism for moving the vehicle between at least two positions for detection by the vision imaging system. The vehicle position adjustment mechanism includes a body, surface support wheels, a motor, and a controller. The body engages the vehicle, and the controller controls the direction and distance the vehicle position adjustment mechanism moves the vehicle. The surface support wheels are connected to the body and support the body on a surface. The motor drives the vehicle between the at least two positions.

Abstract: A wheel balancer comprises a main housing which supports a sub-housing. A main shaft to which a wheel to be balanced is coupled is rotatable in the sub-housing. The sub-housing is pivotally connected to the main housing by a pivot shaft which defines a horizontal main pivot axis extending transversely of the rotational axis of the main shaft. The sub-housing is pivotal from a horizontal position to a vertical position with the main shaft extending upwardly of the sub-housing to facilitate coupling of the wheel to the main shaft.

Abstract: A gearshift linkage for a cab-over-engine type truck having a shift lever extending up through the cab floor enables the forward tilting of the cab on the frame, about the cab pivot axis, without disengagement of the shift linkage and without dislocation of the shift lever from the cab. In the preferred embodiment, a conventional shifter control unit is secured to the cab just below the floor, with the shift lever extending up from the control unit. The control unit is equipped to accept side-to-side movement of the shift lever and translate it into rotation of a control unit output shaft, and to accept forward and rearward movement of the shift lever and translate it into generally forward and rearward movement of the output shaft. The control unit output shaft is connected through a first universal joint to a control shaft which extends forwardly and downwardly from the cab, being connected at its other end to a specially configured universal joint.
