    摘要: Apparatus and a method are disclosed for reducing the transmission power required when a host computer displays video information on a remote video display. A video memory is located in close proximity to the display so that the display can be periodically refreshed in the normal manner from the local memory. Consequently, the host computer need only transmit information regarding the portions of the local memory that have changed since the last data transmission. Since the information for the entire local memory is not transmitted each time the memory must be updated and in particular, each time the display must be refreshed, the required data transmission rate between the host and the display is greatly reduced from the rate normally required with prior art apparatus and, consequently, the power consumption is reduced. In addition, a data and command multiplexing scheme is used to minimize the number of data communication lines which must be used between the transmitting and receiving devices, thus further reducing the power consumed during data transmission.

    摘要: A resonant scanning unit utilizes a "tuning fork" design with a mirror mounted on one arm of the tuning fork and a counterbalance mass mounted on the other arm. A voice coil electromagnetic motor mounted between the arms causes the arms to move in opposite directions. Light generated by a line of LEDs is reflected from the oscillating mirror to generate a raster display. Reaction forces generated by the motions of the mirror and counterbalance mass cancel each other at the device base, reducing vibration. In addition, the inventive structure allows placement of the mirror pivot point away from the center of the mirror which allows display devices constructed with the structure to be reduced in size.

    摘要: A sliding binocular body has two optical assemblies which slide on an intermediate plate to adjust for intraocular distance and which slide closed. Two shells are joined to form one assembly. Front and back contour plates cover the assembly. A field and eye lens holder slides into the box through the back plate. An eye piece is attached to the lens holder. Inward horizontal surfaces have inward extending rails, which engage outward facing grooves on the intermediate plate. The two shells are secured together and joined to the intermediate plate before mirrors are slid and clamped into place. The objective lenses are placed in position, and the contour plates are sealed in place. The eye lens and field lens are inserted in the holders before the holders are inserted in the assemblies. The assemblies hold and clamp mirrors against fixed reference surfaces. Objective lens holders formed in the assemblies permit vertical or horizontal adjustment of an objective lens before its fixing. The intermediate plate has vertical projections on opposite ends which fit into recesses in the inward surfaces of the assemblies to limit outward travel and to hold the assemblies in closed position. The contour cover plates have projections to trap, or transparent extensions to cover, graphic skins or advertising paper boards or wraps.

    摘要: A miniature visual display has an optical lens system with at least two separated lens elements positioned to admit a scanning mirror between them. The scanning mirror is driven with an oscillatory motion causing an image of a light source which is reflected in the mirror to appear to sweep across the field of view of an observer looking into the system. The light source is typically a linear array of light-emitting diodes, and the diodes are controlled to emit light flashes in synchronism with the scanning mirror oscillation frequency to generate a virtual raster image. The two lens elements are selected and arranged so that the magnification power of the system is split between the lenses. A viewer looking into the system sees a virtual image apparently positioned at a comfortable viewing distance which is in uniform focus over the entire viewing area.

    摘要: Light weight, low-cost, compact binoculars intended to be sold at retail locations and popular attractions, such as stadiums, arenas, tourist destinations, and theme parks. The binoculars utilize high reflectance mirrors to fold light and lengthen distance between the objective lens and the field lens to correct the orientation of the image. The binoculars are very light because they are made with mirrors and lightweight, injection molded acrylic plastic lenses. They are pocket sized and compact, yet adjustable for individual interocular distance. The field view is rectangular in format and the IP adjustment is by way of sliding action between nested housings made possible by virtue of the fact that the inversion and reversion functions in its separate housings are in opposite order.

    摘要: A mechanical scanning dual-image display device utilizes two separate scanning mirror mechanisms with a common control that forces the scanning mirrors to move in opposition, and substantially cancel reaction forces. This cancellation is accomplished by providing each of the mirrors with an individual drive mechanism, commonly controlling the two drive mechanisms and arranging the geometry of each display so that the reaction forces acting on the overall display as a result of the mirror motion cancel. In a second embodiment, vibrations are reduced by driving both mirror assemblies from a common source. More specifically, both mirrors are oscillated by an eccentric and linkage mechanism driven by a common motor.
