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 ...

Ronald A Hellekson, Jorge L Acosta, John S Campbell: Shallow bar code scanner. Spectra Physics, Donald C Feix, Paul Davis, T M Freiburger, January 17, 1989: US04799164 (51 worldwide citation)

A compact counter-type bar code scanner produces a "five-apparent-source" scan geometry within an optimum scan volume above the deck of the bar code reader, with a total scanner housing height of less than 13 centimeters, and preferably about 11.5 centimeters. The optics are maximized to achieve app ...

P Guy Howard: Optical beam scanner with rotating mirror. Spectra Physics, Donald C Feix, Paul Davis, T M Freiburger, October 13, 1987: US04699447 (50 worldwide citation)

An optical scanner apparatus particularly suited for use in a laser bar code reader includes a series of mirrors mounted in a basket-like array about the optical beam axis. A mirror is mounted obliquely across the beam axis, directly on the path of the beam, to fold the beam generally radially outwa ...

Ronald A Hellekson, Donald S Peterson: Bar code scanner with DC brushless motor. Spectra Physics, Donald C Feix, T M Freiburger, Paul Davis, November 24, 1987: US04709195 (48 worldwide citation)

A laser scanner having a rotating mirror, such as a POS scanner as used in supermarkets, uses a closed-loop velocity controlled DC brushless motor for rotating the mirror. In addition to providing a hall effect motor speed signal which is used for monitoring and safety features in association with t ...
