摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译： 通常具有三个整体形成的部分的电池触点。 第一端的第一弹簧部分可电连接到可充电电池组。 第二端的第二弹簧部分电耦合到电池充电电路。 保持弹簧部分位于它们之间。 第一，第二和保持弹簧部分由沿着单个导电的扁平金属线制成的一系列弯曲形成。 包含电池充电电路的壳体具有用于接收可充电电池组的插座。 第一弹簧部分由壳体机械地和可移除地保持并且突出到插座中。 第二弹簧部分位于壳体的底壁和包含电池充电电路的印刷电路板之间。 第二弹簧部分电耦合到印刷电路板触点，并且形成为提供具有附加梁弯曲力的多个弯曲部。
