Patent number: 7365991Abstract: Circuit boards for lighting systems have identical LED landing zones printed on the board. Each zone includes at least two sets of LED contact pads. One pad set is configured to mate with contacts of an LED of a first structural type, e.g. from a first product line or manufacturer. The other pad set is configured to mate with contacts of an LED of a second type, e.g. from a different product line or manufacturer. The layout may enable an easy system re-design, e.g. to shift from one type of LED to another. Alternatively, the layout may enable one system to use LEDs of the two different types in a single LED set or array. Exemplary systems disclosed herein include an element for mixing light produced by LEDs mounted to the landing zones, such as an optical integrating cavity.Type: GrantFiled: April 14, 2006Date of Patent: April 29, 2008Assignee: Renaissance LightingInventors: Matthew H. Aldrich, Jack C. Rains, Jr.

Patent number: 7342800Abstract: A high frequency module that has a structure in which a frame-shaped shield case 3 is attached to a circuit substrate 2, wherein an extending segment 331 that extends in an inward direction of the case is formed on a case side plate 31 of the shield case 3, a protruding segment 332 is formed by providing a tip end portion of the extending segment 331 so as to stand perpendicularly, and an engaging portion 332a is formed by swelling out an approximate midpoint of the protruding segment 332 in an inward direction of the case by a drawing process. Furthermore, an inserting hole 21 is formed in the circuit substrate 2 at a location that corresponds to the protruding segment 332. Then, the shield case 3 is attached to the circuit substrate 2 by inserting the protruding segment 332 into the inserting hole 21 of the circuit substrate 2 so that the engaging portion 332a is passed over.Type: GrantFiled: March 6, 2006Date of Patent: March 11, 2008Assignee: Sharp Kabushiki KaishaInventor: Shuhji Matsuura

Patent number: 7233502Abstract: A twin-substrate wireless electronic module includes a main substrate, a plurality of integrated circuit chips, a frame substrate, a filter, and a shield member. The main substrate has a first surface and a second surface, and is formed with a notch that extends from the first surface through the second surface. The integrated circuit chips are surface-mounted on the first and second surfaces of the main substrate. One of the integrated circuit chips disposed on the first surface is a transceiver integrated circuit chip. The frame substrate has a first frame surface and a second frame surface. The first frame surface has a filter-mounting area aligned with the notch. The filter is surface-mounted on the filter-mounting area and is accommodated in the notch. A method for manufacturing the twin-substrate wireless electronic module is also disclosed.Type: GrantFiled: March 15, 2006Date of Patent: June 19, 2007Assignee: Universal Scientific Industrial Co., Ltd.Inventor: Cho-Hsing Chang
