Abstract: A method and structure for reducing dark current in an image sensor includes preventing unwanted electrons from being collected in the photosensitive region of the image sensor. In one embodiment, dark current is reduced by providing a deep n-type region having an n-type peripheral sidewall formed in a p-type substrate region underlying a pixel array region to separate the pixel array region from a peripheral circuitry region of the image sensor. The method and structure also provide improved protection from blooming.

Abstract: An audio power unit is disclosed which provides an audio output and charges removable battery packs as well as providing a number of AC receptacles for powering other tools and the like when the unit is connected to a source of AC power. The unit can optionally also provide DC power. When the unit is connected to a source of AC power, the AC power drives the audio unit which may be a radio or a combination radio and CD player and the AC source also powers a charger which recharges a battery pack if a battery pack is inserted into the charger receptacle. If the unit is not connected to a source of AC power, the radio may be powered by a battery pack when it is placed in the charger receptacle. When the unit is connected to a source of AC power, a relay is opened to isolate the radio unit from the charger and battery pack. The unit has a unique protective frame structure that is connected to the housing of the unit.

Abstract: Process for making a multiple unit fixed prosthesis. A conventionally prepared wax bridge is separated into a plurality of segments, a plurality of brace members are partially interconnected between the segments, and an anchoring member having the general configuration of the wax bridge is prepared for attachment to the segmented bridge by first securing a different support member to each pontic and coping of the bridge and by temporarily securing the anchoring member to a preselected one of the pontics or copings. All of the support members are then permanently secured to the anchoring member by an adhesive that does not introduce distortion into the bridge as it hardens.
