Abstract: A tufting machine has drives for shifting needle bars, pushing needle bars, rocking loopers, knives, and hooks. The drives require less maintenance, result in less wear, are highly accurate, can operate at high speeds and at high loads, and are easily programmable. The drives avoid the need for oil bathes for the moving parts and therefore reduce spillage onto tufted products. The drives are quiet and thus are preferably over many hydraulic drives. The drives are preferably linear drives and, more preferably, are electromagnetic drives.

Abstract: A guidebushing assembly for use with an electric router. A guidebushing holder clamps to the router base, and a guidebushing is secured within the holder and used for cutting an inlay by reference to a female pattern. An appropriately shaped and sized recess is cut by reference to the female template while contacting the template with a tapered sleeve secured to the guidebushing. Movement of the guidebushing and sleeve along the axis of rotation of the router cutter permits adjustment in the size of the recess cut by reference to the template.

Abstract: The present invention relates to devices, systems, and methods for obtaining a quick diagnostic view of a cavity or joint of a patient and/or delivering a therapeutic treatment to that cavity or joint. The invention relates specifically to a cannula device that is sized for insertion into a patient for diagnosis or treatment in an office-based procedure and that has a securing mechanism that allows a scope or other instrument to be adjusted with respect to the cannula. Various optional features of the invention include a rotatable sleeve and an adapter for changing the working length of the cannula. The invention also relates to methods for performing an office-based diagnostic procedure and to kits for assisting the performance of such procedures.

Abstract: A magnetic hinge that connects and secures adjacent components while allowing for rotational movement of the components with respect to each other. The magnetic hinge may be incorporated into a magnetic stand magnifier or a variety of other structures. The magnetic hinge of this invention consists of an arm and a shaft with a magnet therebetween.

Abstract: A video camera mounted on a parking enforcement patrol vehicle and connected to a computer near the operator. The system is driven along a patrol route where parked vehicles are governed by a posted time limit. The system enforces the local parking regulation by automatically determining whether or not each parked car has been parked longer than the posted time limit. Violations are detected by applying a License Plate Recognition algorithm to the images. Each license plate number is time-tagged, geo-referenced and entered into a local database. When the patrol vehicle re-traces the patrol route after the posted parking time limit has expired, the database is searched to flag vehicles that were observed at the same location during the previous circuit and therefore in violation of the parking regulations. When the system detects a parking violation, it prints a parking citation that the operator affixes to the offending parked vehicle.
