Patent number: 11873983Abstract: An LED specification system is provided having at least one LED light output device. The LED light output device has an LED light source, a first exchangeable face panel selectable from a plurality of potential exchangeable face panels, and a housing for locating the exchangeable face panel relative to the LED light source and for orienting the LED light source such that light from the LED light source passes through the first exchangeable face panel. The LED specification system further includes a user interface for selecting at least one preferred output characteristic for light from the LED light output device. The preferred output characteristic is defined by a metric value. The LED specification system further includes a transformation module for defining an LED specification value based at least partially on the defined metric value and a characteristic of the LED light source.Type: GrantFiled: July 13, 2022Date of Patent: January 16, 2024Assignee: BITRO GROUP, INC.Inventors: Edmund C. Kang, Ki S. Lee

Patent number: 4608894Abstract: An adhesive tape cutting device is described. The device comprises a plurality of projections for progressively engaging the tape to unroll it. A concavity is formed on each projection between a pair of tape contacting parts on the top face of the projection. One of the contacting parts is higher than the other and cooperating with an adjacent role carrying a cutter blade to automatically rotate the roller in the movement of the projections for unrolling the tape whereby the cutter blade on the roller enters the concavity in a projection to cut the tape thereon. In a second embodiment the projections are on a belt and sloping projections can also be provided on the belt for engaging and rotating a roller carrying a cutter blade.Type: GrantFiled: February 7, 1984Date of Patent: September 2, 1986Inventors: Ki S.

Patent number: 4159631Abstract: An article of jewelry comprises a hollow spherical housing having upper and lower halves secured together, a disc having gauze-filled cutouts formed therein, internal annular flanges supporting the disc in the housing, and wicks extending between sections of gauze and into the lower half containing perfume. A plurality of orifices in the upper half permit the perfumed vapors to escape. In one embodiment, the disc has a gauze-filled central aperture, and the upper housing half has a central orifice and a coupling ring with an opening aligned with the central aperture and orifice through which a hypodermic needle is inserted to supply perfume to the lower housing half. In another embodiment, the central orifice in the upper housing half is threaded to receive a rod having a threaded portion and an end extending into the disc central aperture, which is devoid of gauze. Removal of the rod permits the lower half to be filled by an eyedropper.Type: GrantFiled: June 1, 1978Date of Patent: July 3, 1979Inventor: Ki S. Lee
