Danial J Tierney, P Guy Howard: Hand-mounted bar code reader. Spectra Physics, Donald C Feix, T M Freiburger, Paul Davis, August 23, 1988: US04766299 (136 worldwide citation)

A hand worn laser bar code reader scanner device is of compact design and adapted to be worn comfortably on the back of the hand of the user. A switch associated with the laser is attached to a hand strap such that the bar code reader is switched on and off by deliberate flexure of muscles in the us ...

P Guy Howard: Hand held bar code reader with modulated laser diode and detector. Spectra Physics, Donald C Fix, Paul Davis, T M Freiburger, September 15, 1987: US04694182 (71 worldwide citation)

A hand held bar code reader employs a laser diode as its laser source, for an efficient and compact construction. The diode is modulated, and an associated bar code reading detector is timed accordingly, so that (1) the effects of strong ambient light which may be present on the bar code surface can ...

P Guy Howard: Hand held laser bar code reader with safety shutoff responsive to housing motion detector. Spectra Physics, Donald C Feix, T M Freiburger, Paul Davis, June 9, 1987: US04672215 (28 worldwide citation)

A hand held laser bar code reader includes a motion sensor and associated circuitry to disable energization of the laser unless the bar code reader has just undergone some degree of motion. This safety feature avoids the possibility of the bar code reader's being held motionless for a long enough ti ...

P Guy Howard, Roeland M T Hekker: Friction wedge alignment system for laser diode collimator pens. Optical Storage International, Edward P Heller III, Joseph A Genovese, September 17, 1985: US04541689 (10 worldwide citation)

A wedge/taper alignment ring is used to hold the objective lens of a laser light pen in place. The ring is free to move in the axial direction under forces of thermal expansion and shock, decreasing distortion and misalignment to the objective. Moreover, it centers the mechanical axis of the objecti ...
