An electronic apparatus such as a computer terminal, video camcorder, portable picture phone or a bar code reader includes a display which is arranged to pivot so as to provide optimum ease of viewing for the user. A reader such as an optical scanner for scanning indicia, for example bar code symbol ...
An optical scanner such as a bar code scanner includes a segmented fold mirror, the individual sections of which have different profiles. By directing the scanning laser beam across the fold mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increas ...
A semi-retroreflective optical scanning system has an optical scanning element which directs a scanning light beam via a stationary holographic optical element in a scan path across indicia to be read. Light from the indicia is collected by an optical collector, such as a lens or a mirror, which foc ...
A radiant energy source, e.g., solar energy, is employed to power an electro-optical reader, preferably by charging an on-board battery. A solar light collector is mounted on the reader in a location exposed to ambient light.
The electron emitting cathode of an initiator (spark plug or ignitor) comprises a small button of high temperature, preferably austenitic, stainless steel powder welded to a support conductor. The stainless steel powder has distributed through it a dopant powder consisting of a minor portion of a hi ...
1,185,078. Portable locks. R. I. N. WEINGART. 20 June, 1967, No. 28290/67. Heading E2A. A portable lock is secured to a recess 18 (Fig. 1), e.g. in the door frame of a door 22, by a hook bar 10, 16 over which is passed aligned slots in a slideway 11 and in a sliding locking plate 14. The plate 14 is ...
An optical scanner for reading indicia having areas of different light reflectivity, such as bar code symbols includes a stationary, multi-surface, fold mirror having a first surface of a first aplanar profile and a second surface of a second, different aplanar profile.
