Patent application numberDescriptionPublished
20080242204 METAL SANDING DEVICES - A multi-tasking disk which in one form is used primarily with a powered hand tool to remove measured amounts of material from the surface of a work piece, and, in another form, serving as a buffing tool for removing minute amounts of skin from feet, elbows and the like on a human, or removal of like minute amounts from vegetables. Each disk is formed with an array of either abrading or buffing elements in which each element involves a series of projections having sharpened edges raised above the surface of the disk to accomplish removal of material from the surface upon which it is engaged.10-02-2008

20100191587TRANSACTION SYSTEM FOR CHARITABLE FUND RAISING, WITH TAX BENEFIT - A system for using financial transactions to raise funds for charitable purposes. A party who uses the system for carrying out financial transactions agrees to pay fee-like contributions for use of the system, such that a portion (up to 100%) of a contribution will be allocated to a charitable entity on behalf of the user. A business entity that facilitates the financial transactions records the details of the transactions and then reports to each user the charitable contribution the user has made through the system. This allows the users to obtain tax benefits on their respective contributions.07-29-2010

20110169117Cross-Talk Suppression in Geiger-Mode Avalanche Photodiodes - An avalanche photodiode detector is provided with a substrate including an array of avalanche photodiodes. An optical interface surface of the substrate is arranged for accepting external input radiation. There is provided at least one cross-talk blocking layer of material including apertures positioned to allow external input radiation to reach photodiodes and including material regions positioned for attenuating radiation in the substrate that is produced by photodiodes in the array. Alternatively at least one cross-talk blocking layer of material is disposed on the optical interface surface of the substrate to allow external input radiation to reach photodiodes and attenuate radiation in the substrate that is produced by photodiodes in the array. At least one cross-talk filter layer of material can be disposed in the substrate adjacent to the photodiode structures, including a material that absorbs radiation in the substrate that is produced by photodiodes in the array.07-14-2011

20080265213Enhanced Leak Detection Dye Carrier - A leak detection dye carrier is formed using a two-stage process (10-30-2008
20090295307Inspection lamp with buck boost circuit control - A lamp for fluorescent inspection having a housing with a first end and a second end. The first end includes a head having at least one LED which emits light with a wavelength designed to excite a material so as to produce fluorescence. The switch controls power the a circuit within the housing for powering the at least one LED. The circuit retards voltage when voltage exceeds a first threshold. In one embodiment the circuit boosts voltage when voltage drops below a second threshold, and blocks voltage when voltage drops below a third threshold.12-03-2009
20090295310Dual head inspection lamp - A dual head lamp having a housing, a first head removably attached to the first end of the housing, and a second head removably attached to the second end of the housing. The first head includes at least one non-white light emitting diode configured to emit light with a wavelength of between 250 nm and 500 nm for fluorescent inspection. The second head includes at least one light emitting diode the emits light having a wavelength that is different than the wavelength of the light emitted from the non-white light emitting diode in the first head. The second head is preferably arranged to emit light in a direction opposite the direction of the non-white light emitting diode. A removable battery compartment is within the housing and configured to hold one or more batteries. A button in communication with a circuit allows for control of power to the light emitting diodes.12-03-2009
20090295311Inspection lamp with elongated diffuser lens - An inspection lamp is disclosed that, in one embodiment, includes a transparent or translucent rod having two ends. Two light sources, one at each end of the rod, are arranged to emit light into the rod toward one another. The rod is located within a housing that has an opening. A reflector is located within the housing to direct the light in the rod toward the opening.12-03-2009
20100044589Modular lamp head and assembly for non-destructive testing - A lamp module for use in non-destructive testing and inspection. The module including a module body with a front and rear end, and a side wall. The module body includes a mounting chamber located within the side walls. A plurality of LEDs are mounted within the chamber and oriented to so as to emit light out of the front end of the body. At least one LED emits light having a wavelength selected to produce fluorescence of an illuminated material. A fan is mounted to the body to dissipate heat generated by the LEDs when the fan is activated. Electrical connectors extend out of the body and are electrically connected to the LEDs and the fan for supplying current. The module can be installed in various structures or systems, including in a luminaire, an overhead light housing or a track light system.02-25-2010
20100060197Inspection Lamp with Interchangeable LED Light Source Module - An inspection lamp includes a housing with an external opening providing access to a socket having an electrical contact, an interchangeable light source module including a tab adapted to be inserted into the opening and received into the socket, the tab including a mating electrical contact for making an electrical connection with the electrical contact of the socket, the light source module including at least one light emitting diode, and a switch for controlling the light emitted by the light source module.03-11-2010
20110050123Inspection Lamp with Interchangeable Mount - An inspection lamp with interchangeable mount including a housing having a front and rear, at least one blue/ultraviolet LED for emitting light in a blue/ultraviolet wavelength range from the front of the housing, at least one white LED for emitting broad spectrum visible light from the front of the housing, a mounting apparatus for removably mounting the housing to a mounting fixture, the mounting apparatus including a lamp adapter, and a slot located in the rear of the housing for slidably receiving the lamp adapter.03-03-2011
