Abstract: A toothbrush providing a radiation source of selected optical range, having the radiation source built into a cavity in the handpiece of the toothbrush. The brush head may be transparent and the bristles may be transparent. Various combinations of scattering, transparent and reflective properties of the brush head, the type of radiation source, and bristle transparency allows selected influence directly on different field and tissues of the oral cavity. Radiation wavelength is selectable to provide treatment to both the soft tissue of the oral cavity and to the teeth. Selected radiation penetrates the pulp of the tooth to stimulate and enhance calcium transport to the dentine and enamel of the tooth to prevent and treat cavities.

Abstract: A system and method for supercharging an in-line engine is disclosed. The system comprises a "bolt-on" supercharger system that is attachable directly to an existing installed engine without significant modification of the engine. The system includes an intake manifold fabricated preferably from aluminum and appropriately sized to the particular engine and available space, and which is removably attachable to the stock intake manifold of an engine in flow communication with the stock intake manifold; a supercharger removably attachable to, and in flow communication with, the fabricated intake manifold, by use of an adapter plate; a bypass valve assembly attached between and in straight line flow communication with a carburetor or fuel injected system and the supercharger. The bypass valve is joined to the carburetor by a bypass adapter ring, and allows an air-fuel mixture from the carburetor to bypass the supercharger and go directly into the fabricated intake manifold when the system is not in a boost mode.

Abstract: A stable work bench (1) that is easy to adjust in height regardless of the load on the platform (8) has an upper platform (2) and a lower base element (3), a frame that is variable in height and arranged between the platform (2) and the base element (3), each end of which frame has an upright first leg (4) and a second leg (5) disposed parallel thereto and at a horizontal distance therefrom that supports the underside of the platform (2), which legs (4, 5) are pivotably connected by a lower arm (6) and an upper arm (7) parallel thereto to produce a deformable parallelogram (4-7), and with a drive system to raise and lower the platform (2) of the work bench (1) by changing the angle between the parallel arms (6, 7) and the upright first leg (4).

Abstract: A system and method to deter the theft of paper currency comprising a currency pack assembly containing coded electronics and an ignitable chemical pack. There is a coded teller sentry unit located near the cash drawer in which the currency pack assembly is stored. The currency pack assembly contains a coded transmitting/receiving apparatus that signals the coded teller sentry unit when the currency pack assembly is removed from the cash drawer. The coded teller sentry unit is connectable to a silent alarm and may trigger the silent alarm upon removal of the currency pack from the cash drawer. The coded teller sentry unit is also connectable to surveillance equipment such as cameras, and activates such equipment automatically upon removal of the currency pack assembly from the cash drawer. There is also a coded door control unit located near the egress to the building which detects when the currency pack assembly has left the building.
