An apparatus, system and method for testing a peripheral device such that the device can remain installed in a housing and connected to a communication bus such as a SCSI bus. The apparatus, system, and method include a communication port that is connectable to a peripheral device connected to a terminated communication bus. The communication port is connected to a first transceiver and a second transceiver. A microcontroller is also connected to the first transceiver and the second transceiver. The microcontroller is programmed to detect an operation mode for the peripheral device and selectively activate the first transceiver or the second transceiver based on the detected operation mode. The microcontroller is further programmed to perform a logical diagnostic test on the peripheral device using the activated transceiver. A user interface is included to communicate to a user a result of the diagnostic test.

Multi-mode SCSI diagnostic tool, system, and method

A housing for an information storage medium where at least one surface of that housing includes a plurality of grooves. A locomotion apparatus to move Applicants' housing within an information storage and retrieval system, where that apparatus includes at least one rotatable shaft and at least one drive member disposed on that shaft, where each such drive member has the shape of a truncated cone, and where each such drive member includes a drive surface which includes a plurality of ribs. Applicants' drive member contacts the grooved surface of Applicants' housing such that one or more of the ribs disposed on the drive surface intermeshes with one or more of the grooves in the housing. Rotation of the rotatable shaft in a first direction causes the housing the move in a second direction. Rotation of the rotatable shaft in a third direction causes the housing to move in a fourth direction.

A bar code reader for an automated storage library has a lens assembly with a pair of polarized liquid crystal lenses. Each lens has pair of parallel glass plates that are separated by upper and lower glass substrates. A series of polymer films are symmetrically spaced apart between the substrates. Both the substrates and the films are perpendicular to the glass plates. Electrodes are formed on the films and combine to form a semi-cylindrical stack of film. Liquid crystal fills the spaces between adjacent pairs of the films. The films are coated and/or treated by an alignment process to predispose the liquid crystals to a specific rotational direction. When a selected voltage is applied between adjacent ones of the electrodes, the liquid crystals are synchronously rotated to alter their refractive index to a desired value. Thus, when the layers of each lens are manipulated in unison, the bar code reader is able to quickly adjust its focal length to read bar codes at various distances.
