James D Kafka: Laser diode pumped fiber lasers with pump cavity. Spectra Physics, Paul Davis, May 9, 1989: US04829529 (80 worldwide citation)

A fiber laser having a single mode fiber core of laser material is pumped by a high power coherent laser diode source by providing a multi-mode fiber around the single mode core to define a pump cavity which propagates pump radiation while allowing the pump radiation to couple to the single mode cor ...

Thomas M Baer, Mark S Keirstead: Laser diode pumped solid state laser. Spectra Physics, Paul Davis, April 7, 1987: US04656635 (79 worldwide citation)

A neodymium or other rare earth doped solid state laser is pumped by a matched high efficiency laser diode, resulting in a compact, high efficiency and long lifetime laser assembly. Output is in the near infrared range, but can be converted to the visible spectrum by an intra-cavity frequency double ...

Joseph F Rando: Multiple window scanner and method for multiple focal distance reading. Spectra Physics Scanning Systems, Lyon & Lyon, February 9, 1999: US05869827 (76 worldwide citation)

A multiple window data reading device and method for reading symbols such as bar codes through each window, data reading being focused to different focal distances in the scan volume with sensors provided to control focal distance setting from each of the windows.

Jonathan Brandon Allen, Deepen Sinha, Mark R Sydorenko: Perceptual audio compression based on loudness uncertainty. Lucent Technologies, Thomas A Restaino, October 28, 1997: US05682463 (76 worldwide citation)

A new technique for the determination of the masking effect of an audio signal is employed to provide transparent compression of an audio signal at greatly reduced bit rates. The new technique employs the results of recent research into the psycho-physics of noise masking in the human auditory syste ...

Joseph F Rando: Creation of three dimensional objects. Spectra Physics, Donald C Feix, Paul Davis, Thomas M Freiburger, April 10, 1990: US04915757 (76 worldwide citation)

Three dimensional objects or models, such as three dimensional images or shapes stored in a computer, are generated as real models by addition of material to a base, such as with photo-hardenable liquid, or by removal of material from an initially oversized mass. Optical feedback is employed to mono ...

Joseph F Rando: Laser beam level instrument. Spectra Physics, Donald C Feix, September 9, 1980: US04221483 (76 worldwide citation)

A lightweight, portable laser beam level instrument has an optical path which includes a solid state light source; a pendulous, positive lens; a rotatable pentaprism or mirror equivalent; and a glass plate which is tilted to provide fine tuning. The level instrument also includes a damping mechanism ...

Robert B Slusher: Single axis beam scanner. Spectra Physics, Donald C Feix, June 14, 1983: US04387952 (73 worldwide citation)

Two concave spherical metal mirrors are used to scan a continuous wave laser beam for heat treating of metals. The mirrors are rotated in opposite directions and each is tilted at a small angle with respect to its axis of rotation. The frequencies of rotation of the mirrors are made constant by a pr ...

Anthony J Baerlocher, Anna Sheila C Parrucho, Cari L Blomquist: Gaming device having outcomes which replicate the laws of physics. IGT, Bell Boyd & Lloyd, January 30, 2007: US07169044 (72 worldwide citation)

A processor controlled gaming device that randomly generates and displays a pachinko-type game and outcome on a screen connected to the processor. The gaming device initially provides a preliminary game that yields the number of attempts or objects that the player has in the pachinko-type game. Next ...
