Abstract: In a high voltage, variable frequency radiation generation system, a carrier signal supplied to a primary coil of a transformer is varied, e.g., turned ON and OFF at variable frequencies. The ON duration and/or the average amplitude of the carrier signal may also be varied. Moreover, the carrier signal may be modulated using an audio signal. The parameters to control the variation of the carrier can be provided as a recipe via a software application. A server can provide different types of apps providing different control features. The server may also collect user characteristic data and recipe usage data, and may facilitate exchange of these data and may recommend recipes based on a particular user characteristic.

Abstract: A door handle assembly having a snap-in attachment apparatus for assembling a key cylinder to a door handle assembly without the use of separate fasteners and retainers. The door handle assembly has a bored tubular extension that utilizes slots to define tubular sections that yield radially outward upon inserting the key cylinder into the bore of the tubular extension. The tubular sections have openings that receive lugs extending from the periphery of the key cylinder and that prohibit inward axial movement and rotary movement of the key cylinder. A shoulder in the door handle assembly abuts an end of the key cylinder to prohibit outward axial movement of the key cylinder. The engaging surfaces of the lugs and tubular sections have drafted angles that pull the tubular sections radially inward toward the key cylinder upon a push-in force applied to the key cylinder from outside the vehicle and directed toward the center of the vehicle.

Abstract: The die cast metallic door handle adapted for attachment on the vehicle door has a molded plastic insert attached thereto on the face thereof facing toward the vehicle so that a user gripping the door handle places his fingers against the molded plastic insert to insulate his fingers from the temperature of the metallic handle. In addition, a molded plastic push button assembly including a molded plastic housing and a molded plastic push button are attached to the metallic handle so that the user's thumb pushes against the molded plastic push button instead of a metallic handle. In addition, the push button assembly has the molded plastic push button slidably guided on a pin which is encircled by a spring acting to position the push button. The push button assembly may be preassembled prior to its attachment to the handle so that push button assembly may be pretested prior to attachment to the handle.
