Title: Virtual retinal display
Inventor: FURNESS THOMAS ADRIAN III
IPC: G02B27/00
Filed: 1993-10-04
Granted: 2003-12-09
Abstract: A virtual retinal display utilizes photon generation and manipulation to create a panoramic, high resolution, color virtual image that is projected directly onto the retina of the eye without creating a real or an aerial image that is viewed via a mirror or optics (18). The virtual retinal display includes a source of photons (12), the photons being modulated (14) with video information (40) and scanned in a raster type of pattern directly onto the retina of the user's eye. The photon generator (12) may utilize coher-ent or non-coherent light. Further, the photon generator may utilize color light generators (80, 82, 84) so as to scan a colored virtu-al image directly onto the retina of the user's eye. The virtual retinal display may also include a depth accommodation cue to vary the focus of scanned photons rapidly so as to control the depth perceived by a user for each individual picture element of the vir-tual image. Further, an eye tracking system (106) may be utilized to sense the position of an entrance pupil of the user's eye, the detected pupil position being utilized to move the scanned photons so as to be approximately coincident with the entrance pupil of the eye.

Abstract: An ion source (12) embodying the present invention is for use in an ion implanter (10). The ion source comprises a gas confinement chamber (76) having conductive chamber walls that bound a gas ionization zone. The gas confinement chamber includes an exit opening (78) to allow ions to exit the chamber. A base (120) positions the gas confinement chamber relative to structure for forming an ion beam from ions exiting the gas confinement chamber. A gas supply is in communication with the gas confinement chamber for conducing an ionizable gas into the gas confinement chamber. A cathode (124) is supported by the base and positioned with respect to said gas confinement chamber to emit ionizaing electrons into the gas ionization zone. The cathode comprises a tubular conductive body (160, 162) that partially extends into the gas confinement chamber and includes a conductive cap (164) that faces into the gas confinement chamber for emitting ionizaing electrons into the gas confinement chamber. A filament (178) is supported by the base (120) at a position inside the tubular conductive body of the cathode for heating the cap and cause the ionizing electrons to be emitted from the cap into the gas confinement chamber.

Abstract: A material handling and transport system for transporting goods between a number of discharge/induction stations and selectively receiving and discharging goods at the stations.  A moving transport unit (24), for example a train-type string or cars (28, etc.) or trolleys with tilting trays (70, etc.) for receiving, transporting and discharging goods between induction (38) and discharge stations (52, etc.) positioned along a track (22), incorporates a number of self-contained, locally controlled sensing (58), signal (62, etc.) and actuation (30) devices which allow the trolleys to selectively interact with passive stations around the track.  The centralization of systems control (54) on the trolleys themselves, as opposed to on the track-side stations, results in greater system flexibility, reduced cost, and allows the train to operate in essentially autonomous mode without the need for external control and monitoring.
