The control circuit includes a direct current energy source, and an oscillator connected to the energy source for generating a predetermined series of regularly timed energy pulses having a selected frequency and duty cycle to cause excitation of the motor in response to the energy pulses.

Abstract: An omnibearing display, having a display face, with the blanking element in front of the display face, is rotated with a high speed by a rotation actuating mechanism to cyclically and repeatedly appear to eyes of an observer around the display face within a duration of persistence of vision. This results in an effect that observers at any positions around the display face will see the same display face within the duration of persistence of vision, namely, the omnibearing display effect.

Abstract: A swing type aerial display system is adapted to aerially display a desired visual image utilizing a residual image effect of a moving light emitting array. In order to establish synchronization of the motion of said moving light emitting array and illuminating timing of individual cells in the light emitting array, the motion behavior of the system is monitored and timing to drive each individual cell is controlled in relation to the monitored motion behavior of the light emitting array, so that the desired image becomes visible at a desired position and desired configuration.

Abstract: A parallel computing system producing, storing, and processing voxel data elements in parallel within a three-dimensional memory storage array, and producing and buffering pixel data elements in parallel for use in volume visualization of the stored voxel data elements. The parallel computing system includes a system bus for transferring parameters and local programs. A plurality of local computing units are connected to the system bus. Each local computing unit has a local program storage memory for storing one or more local programs, and RISC processor for executing the local programs. A local memory storage module is connected to each local computing unit. Each local memory storage module has a set of memory storage elements, each of which is capable of storing one or more voxel data elements. A plurality of the memory storage elements in the local memory storage modules are indexed so as to represent the three-dimensional memory storage array in 3-D space characterized by three coordinate directions.

Abstract: A display apparatus in which light outputted from an LED array arranged in a column is reflected by a vibrating mirror such that a two-dimensional image is obtained, comprising: a half mirror which reflects light having a wavelength identical with a light emitting wavelength of the LED array and transmits therethrough visible light having other wavelengths than the light emitting wavelength; the half mirror being so disposed as to not only transmit therethrough the visible light from outside but also reflect the light proceeding from the LED array via the vibrating mirror such that the two-dimensional image has an outer scene as its background.

Abstract: A display comprises a static unit (8) on which is mounted a rotating unit (7) driven by a motor (12). The rotating unit carries light emitting diodes (6) arranged as vertical columns which sweep around a cylindrical surface. The light emitting diodes (6) are controlled by a control circuit (6) in accordance with data stored in a memory (61) so as to provide a cylindrical display. The control circuit (60) and memory (61) are located in the rotating unit 97) and the memory (612) has a capacity for storing several different images for display.

Abstract: A pulsed laser optical display device includes a source of an image bit map. Activation signals are generated from the image bit map, and used to control the firing of laser diodes arrange in banks and oriented so that the resulting beams impinge upon a rotating polygonal mirror which reflects each beam to impinge on a projection surface, the rotating mirror serving to sweep the beams over the projection surface. Rotation of the mirror is synchronized with activation of the the diodes, so that an image corresponding to the bit map is displayed. Both front-projection and rear-projection surfaces, such as an automobile instrument panel and a heads-up display, can be illuminated simultaneously.

Abstract: An optical display system is disclosed having a preferred application in a helmet mounted heads-up display. The display system includes an image source (42-46) for generating an image which includes a plurality o fields sequentially displayed by the image source to form the image with a two-dimensional array of pixels forming each field and the fields having a spatially modulated light intensity. An image display (50) is coupled to the image source for displaying the fields. The image display produces for each field a two-dimensional display having a fixed number of light emitting points (65) which are disposed along each dimension of the two-dimensional array with each light emitting point being spaced apart from adjacent light emitting points by a fixed distance.
