Abstract: A battery contact generally having three integrally formed portions. A first spring portion at a first end is electrically couplable to a rechargeable battery pack. A second spring portion at a second end is electrically coupled to a battery charging circuit. A retaining spring portion is located therebetween. The first, second and retaining spring portions are formed by a series of bends made in and along a single, electrically conductive, flat metal wire. A housing containing the battery charging circuit has a socket for receiving the rechargeable battery pack. The first spring portion is mechanically and removably retained by the housing and projects into the socket. The second spring portion is positioned between a bottom wall of the housing and a printed circuit board containing the battery charging circuit. The second spring portion is electrically coupled to a printed circuit board contact and is formed to provide multiple bends with additive beam flexure forces.

Abstract: An apparatus for reading a bar code symbol with an illumination beam of light. The apparatus includes an integrally formed lens with a first lens surface for transmitting the beam of light toward the bar code symbol along an optical axis and second and third lens surfaces for receiving any of the beam of light that is reflected from the bar code symbol and transmitting the received light along two distinct optical paths to two photodiodes. The two distinct optical paths are separated from each other and not aligned with the optical axis. The configuration of lenses provides an improved depth of field.

Abstract: A latch for securing a panel within an overhead opening includes a base portion which is secured to the panel. A cam is pivotally mounted to the base and is biased such that upon insertion of the panel into the opening a foot on the cam snaps over adjoining structure, pinching the structure against the base and thereby securing the panel. A trigger mechanism pivotally mounts to the cam and is configured to lock the cam in an unlatched position upon desired removal of the panel.
