Abstract: A laser scanning module employing a laser scanning assembly mounted within a module housing using a mechanism that allows the laser scanning assembly to be rotated to an angular position within the engine housing so that light collection, beam folding and light collection mirrors in the module housing are optically aligned. A PC board is mounted on a side of the housing and has a configuration of elongated apertures of open-ended and/or closed geometry, arranged in a non-parallel manner. An electromagnetic coil structure, associated with the laser scanning assembly, has a linear array of electrically-conductive pins that project through the configuration of elongated holes, at locations along the elongated holes that are determined by the angular rotation of the laser scanning assembly attained during optical alignment conditions during manufacture.

Abstract: There is described a focusing apparatus having a deformable membrane that at least partially defines a cavity and an optical fluid disposed in the cavity. An actuator assembly can be provided for imparting a force to the deformable membrane. In one embodiment, the actuator assembly can include a piezoelectric actuator.

Abstract: Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.

Abstract: The invention is an apparatus and method for attaching a lens to a image scanner housing. In the present invention a lens is secured to a housing by a clamping force supplied by a closed peripheral wall which forms a housing tip, and a shelf which is rigidly formed in the housing interior. The closed peripheral wall contacts the top surface of the housing, and the top surface the shelf contacts the bottom surface of the lens, to hold the lens in a secure position. A substantially soft, friction-producing member such as an o-ring may be interposed between the shelf and the lens to absorb shock, to provide a tolerance between the lens and the shelf, and to prevent rotation of the lens.
