Abstract: An edge dressing grinder tool used for making a continuous straight, vertical edge on a concrete, natural stone or artificial stone slab used for a countertop or table. The tool includes a manually operated hand grinder with a perpendicularly aligned grinding disc or pad mounted on a drive shaft. Attached to the head of the grinder is a forward extending, longitudinally aligned bracket. Extending laterally from the bracket are two slide arms and an adjustment rod. Mounted on the distal ends of the slide arms is a guide plate with a low friction, sliding plate. Mounted along the rear edge of the guide plate are two, transversely aligned wheels that press against a raised edge formed on a rigid fence that is fixed in position on the top surface of the work piece and parallel to the edge. The end of the adjacent rod engages a nut assembly mounted on the slide plate that allows the distance between the grinder's head and the guide plate to be selectively adjusted.

Abstract: A system and method of detecting and signaling the activation of a spring-loaded rat trap located at a remote location. The system includes a wireless transmitter mounted inside a transmitter unit upon which a spring loaded rat trap is placed. When a rat is caught by the trap, the rat drags the trap over the top surface of the transmitter unit causing activation of one or more switches located on the top surface. The switch is coupled to the wireless transmitter that sends a signal to a wireless receiving unit located in the vicinity. Coupled to the receiving unit is a light or sound alarm that is activated when a signal is received from the transmitter unit indicating that the trap has been moved over the transmitter unit. The system may be used with one or more transmitter units so that system may be used to monitor rat infestation one or multiple locations.

Abstract: An apparatus and method for treating sleep apnea comprising an external, low voltage electrical stimulator that provides between 5 to 25 milliamps connected to electrodes imbedded located over the first and third intercostals or the third and fifth intercostals. The stimulator is designed to provide a current to the electrodes that stimulated one of the two pairs of intercostals for 59 seconds, rest for 4 seconds and then repeats the cycle throughout the night after the user has fallen asleep. The stimulator includes a main power switch and two amplitude control switches (also called amplitude control switches), a main control switch, an adustable delay activation timer switch, a power timer switch, an amplitude lock switch, two channel electrode wire plugs, an LCD display, and a battery pack. Prior to use, the amplitude control switches adjusted and lock at an amplitude needed to cause contraction. of the intercostals assigned to the channel.

Abstract: A shower head designed to produce a consistent, wide diameter spray of water under both high and low water pressure conditions. The shower head includes a spinner tube mounted inside a cylindrical-shaped nozzle body. The upper segment of the spinner tube is held in a central location inside the nozzle body by a fixed cassette assembly. The middle and lower segments of the spinner tube extend below the cassette assembly and are bent outward and axially offset from the upper segment and from each other so that the spinner tube is able to spin freely inside the nozzle body. Mounted inside and over the upper end opening of the nozzle tube is an adapter with a longitudinally aligned threaded cavity formed on one end. The adapter includes a water orifice that delivers water from the shower head fixture tube to to the spinner tube. Disposed between the adapter and the upper end of the spinner tube is a flat washer with a narrow water orifice that delivers a narrow, high velocity stream of water to the spinner tube.

Abstract: An anti-theft and file security system for a portable electronic device that uses a wireless transceiver coupled to the electronic device, which detects an identifying RF signal produced by a wireless access point. In the preferred embodiment, the access point is connected to a local or wide area network within a geographical area in which the portable electronic device is operated. During use, the RF signal from the access point is detected by a wireless transceiver. Loaded into the memory of the electronic device is a software program that determines if the RF signal is produced by a recognized access point. If the RF signal produced by the access point is recognized, then the electronic device continues to operate and allows full access to secured files loaded thereon. If no RF signal is detected or if the detected RF signal is from a non-recognizable access point, then operation of the electronic device is terminated and/or access to the secured file is blocked.
