Abstract: Briefly, in accordance with one embodiment of the invention, a plug-in type application may intercept called functions in order to implement one or more security or digital rights management type settings, and/or one or more policies for a given document where such functions may be restricted, prohibited, and/or otherwise controlled. Patch code may be integrated with such controlled functions to modify the behavior of the function when executed in order to comply with the security or digital rights management setting, and/or one or more policies.

Abstract: A multiple feed document detection system for use with a document transport for detecting the presence of multiple documents utilizes multiple doubles detection devices wherein each device detects the presence of doubles. The output signals of each device are applied to a comparator which compares the signals obtained from each device. If each device indicates the presence of doubles, then the comparator provides an output that multiple sheets are present. The system thereby eliminates the reading of false doubles by the comparison of the output signals from two or more doubles detection devices.

Abstract: An improved accordion-like folding cover for open truck beds includes a flexible waterproof canvas cover overlying a plurality of elongated metal panels hingedly joined to form a cover assembly. The cover assembly is foldably mounted between a pair of guide tracks which are attached to the upper surface of the side walls of the truck bed; the tracks being attached to the side walls by bolts which are concealed from the exterior of the closed truck bed. An improved locking mechanism comprises a handle and a pair of attached locking arms which extend perpendicularly to and selectively into engagement with the tracking components. By turning the handle, the locking arms are retracted or extended into selected ones of a plurality of slots in the side walls of the tracks for holding the cover in a plurality of positions including fully opened, partially opened, or completely closed. The handle may be locked by a key and the locking arms are concealed beneath the cover assembly for security.
