Abstract:
An integrated light-emitting diode (LED) indicator display assembly having a carrier plate including a plurality of LED mounting steps. Electrical contact leads for LEDs carried on the mounting steps extend through openings in the mounting steps and out the bottom side of the carrier plate for engaging a metal fret to power the LED array. Preferably, a vibration dampening member is positioned between the LED and the LED mounting step, and a protective covering is applied over the metal fret along the bottom side of the carrier plate to enclose the metal fret and secures the metal fret in place.

A second substrate 2 to be joined with solder to a first substrate 1 is bent with elasticity generated by a bending portion 9, and first joints 5 on the first substrate 1 and second joints 6 on the second substrate 2 are joined with solder in a state in which the first substrate 1 is brought into contact with, in a direction that increases the bending angle of the bending portion 9, a part where the joints 6 are formed on the second substrate 2.
Abstract:
An LED lighting array is disclosed wherein a plurality of light emitting devices disposed in at least first and second columns are mounted on a planar mounting surface to form an emission plane. The emission axes of all the LEDs in a first column are parallel with each other and lie in a first plane. The emission axes of the LEDs in an adjacent, second column are also parallel, but a second plane containing the emission axes of the second column is disposed at a predetermined, non-zero angle with respect to the first plane. The non-zero angle is a function of the LED beam width and the distance to a lighting target. This configuration of the LEDs provides an optimum balance at a predetermined target distance between the size of the area illuminated and the brightness of the illumination of the target. In one aspect of the invention the LED lighting array includes at least first, second and third columns of LEDs. In another aspect of the invention an LED task light includes a transparent tube and an LED lighting array disposed within the tube. An electrical drive circuit associated with the mounting substrate within the tube provides pulsed direct current for driving the LED's.

Abstract:
A lead-mounting seat includes a conductive seat body including a lead-mounting plate and spaced apart first and second insert legs that extend from the lead-mounting plate and that have different geometric shapes. The lead-mounting plate is formed with a plurality of lead-mounting holes. Each of the first and second insert legs has a connecting end connected to the lead-mounting plate, and a free end opposite to the connecting end. Each of the first and second insert legs is reduced in width from the connecting end to the free end.
Abstract:
An assembly is provided which includes a first circuit panel having a top surface, a first dielectric element and first conductive traces disposed on the first dielectric element. In addition, a second circuit panel has a bottom surface, a second dielectric element and second conductive traces disposed on the second dielectric element, where at least a portion of the second circuit panel overlies at least a portion of the first circuit panel. The assembly further includes an interconnect circuit panel having a third dielectric element which has a front surface, a rear surface opposite the front surface, a top end extending between the front and rear surfaces, a bottom end extending between the front and rear surfaces, and a plurality of interconnect traces disposed on the dielectric element. The bottom end of the interconnect element abuts the top surface of the first circuit panel and the top end abuts the bottom surface of the second circuit panel, where at least some of the first conductive traces are in conductive communication with the second conductive traces through the interconnect traces.
Abstract:
A very small computer memory card is densely packed with a large number of flash EEPROM integrated circuit chips. A computer memory system provides for the ability to removably connect one or more of such cards with a common controller circuit that interfaces between the memory cards and a standard computer system bus. Alternately, each card can be provided with the necessary controller circuitry and thus is connectable directly to the computer system bus. An electronic system is described for a memory system and its controller within a single memory card. In a preferred physical arrangement, the cards utilize a main circuit board with a plurality of sub-boards attached thereto on both sides, each sub-board carrying several integrated circuit chips.
