Abstract: A combined signal level meter and leakage detector having a built-in antenna for the leakage detector, and dual clock frequency control of the microcontroller along with bandwidth switching for greater sensitivity in leakage detection mode. A data logging function is also provided. Control circuitry is also provided for avoiding receiver spurs by combined switching of multiple local oscillator frequencies, including combinations of high-side and low-side injection and IF shifting.

Abstract: A selective opacity, maximally transverse retracting sunroof system for a vehicle roof is retrofitted to a vehicle by removing most of the original vehicle roof side rails and attaching thereto a strut assembly capable of supporting a self-contained sunroof mechanism to be attached thereto. The sunroof panel of the mechanism then is capable of covering the vehicle roof aperture from side rail-to-side rail. To decrease the undesired effects of a large, clear roof, the sunroof panel opacity may be chosen by the operator. Opacity of the panel is electrically controlled and provision is made for supplying power to the sunroof panel throughout its range of movement. A second, selective opacity roof panel may be used in the vehicle roof structure to maximize the light transmitting area of the roof.

Abstract: A flexible fabric sunroof retracts by means of cable driven guide shoes driving a front header to the open position and thereby moving odd numbered position bows 3 and 5 along horizontal side tracks within the roof. Even numbered position bows 2, 4 and 6 are biased upwardly to lift the slack fabric above the roof plane during retraction. The fabric sunroof may be totally removed from the roof structure to provide for the largest possible roof opening by removal of a rear header attached to the rear roof frame and detachment of the front header from the guide shoes. A wind deflector is provided which is concealed within sunroof when in the closed position.

Abstract: A sliding sunroof assembly for a vehicle and a latching mechanism for such a sunroof assembly are disclosed.A gear shaft has two drive gears disposed on opposite ends thereof which ride on gear guides on tracks, the gear guides having serrations formed thereon to engage teeth of the drive gears. A lock gear is provided centrally on the gear shaft, and one or more engaging members are normally biased into engagement with the lock gear to prevent rotation of the shaft. Movement of a handle disengages the engaging member or members from the lock gear, allowing the gear shaft to spin and allowing slidable movement of a sunroof panel. The latching mechanism enables the sunroof assembly to be latched in a plurality of positions between a fully closed portion and a fully open position.
