Abstract: A virtual image display system provides video displays based upon virtual images of the external world having synchronized structural outlines superimposed on the video displays to a pilot operating an aircraft such as a helicopter in non-visual flight conditions. The virtual image display system includes a virtual imaging subsystem for generating virtual images of the external world, a video display subsystem for generating video images based upon the virtual images and for displaying the video images for the pilot's viewing, a sensing means for providing signals corresponding to the spatial location and perspective of the video display subsystem, a map comprising structural outlines corresponding to structural members forming the canopy structure of the helicopter, and a computer subsystem providing electronic interfacing between the elements of the virtual image display system, for synchronizing the orientation of the virtual imaging subsystem with the video display subsystem, and for processing the virtual image signals to provide signals to the video display subsystem to generate video displays. The computer utilizes the helmet position signals to define the relative position and orientation of the video display subsystem in the cockpit, and utilizes such definition to reconstruct structural outlines from the map that are synchronized to the perspective of the video images. The synchronized structural images are superimposed upon the video display.

Filed: 1993-07-22
Abstract: This invention relates to a method and apparatus for improving the performance of intelligent networks. In a departure from the prior art, when a data base system, such as a service control point (11), receives an inquiry from a switching system (2), if the data base system recognizes that it cannot provide the complete data requested by the inquiry, it directly launches another inquiry to another data base system (12) to provide the missing data. Advantageously, such an arrangement reduces the number of messages transmitted among switching systems (1,2) and data base systems (11,12,13).

Abstract: A voltage-follower circuit has an input biasing stage that generates an input stage bias current and a tracking bias current. An input stage generates an intermediate voltage signal and sources an input current in response to an input voltage signal and the input stage bias current. An output biasing stage generates an output bias current. An output biasing stage generates an output voltage signal and sinks a portion of the input bias current in response to the intermediate voltage signal and the output bias current. A cancellation stage sinks substantially all of the input current in response to the tracking bias current. A cascode stage isolates the input biasing stage from the input stage and the cancellation stage. A compensation stage sinks a portion of the tracking bias current which is substantially equivalent to the portion of the input bias current sunk by the output stage.

Abstract: A data switch interconnects a number of data processing nodes. The switch includes a number of port units for interfacing with the processing nodes, a number of multiplexing units for performing the switching, and a connection control unit. When a port unit wishes to initiate a connection, it sends a connection command over a command bus to all the multiplexing units and to the connection control unit, specifying a proposed data connection. Each multiplexing unit responds to the connection command by preparing the proposed data connection. At the same time, the connection control unit checks whether the proposed data connection is permissible. If it is permissible, the connection control unit then sends a GO signal to all the multiplexing units instructing them to complete the prepared connection.

Abstract: The wavelength converting device comprises a BBO crystal of length L along the propagation direction of incident light C and a filter transmitting only light E by second harmonic generation. The BBO crystal is composed of 10 pieces of crystal equally divided in parallel planes along the propagating direction of the light. Each crystal piece has a crystal axis respectively and is positioned with the crystal angle satisfying a phase matching condition for second harmonic generation and so that the adjacent crystal axis is oriented in a crystallographically different way. The acceptance angle φ in the insensitive direction becomes the same as the acceptance angle ϑ in the sensitive direction; therefore, there is no necessity for gathering light to an oval shape, and maximum conversion efficiency can be obtained by gathering light with a conventional spherical lens.

Abstract: A planar, topology free, semiconductor quantum-well laser is described. The quantum-well active layer is formed and patterned in a specified region which is constrained on all sides by high bandgaps which are formed through the use of impurity-free diffusion techniques. After the impurity-free diffusion has taken place, an upper portion is then epitaxially deposited to complete the structure. High-power, single fundamental mode laser operation is achieved by funneling current into the constrained quantum-well active region, high bandgap regions in conjunction with low index of refraction in regions surrounding the active area. 
     The structure is further designed to allow low beam divergence in the direction perpendicular to the semiconductor laser junction.

Abstract: A Video-On-Demand (VOD) scheduler maintains a queue of pending performance for at least one movie and determines a maximum wait tolerance time for a longest waiting one of the pending performance requests. When stream capacities become available, rather than scheduling the movie immediately the scheduler delays performance of the video until just prior to expiration of the maximum wait tolerance time of the longest waiting one of the pending performance requests. In the interim, additional streams can join queue. When the performance occurs all performance requests on the queue are served from the a single stream provided from the assigned stream capacity.

Abstract: A one-ply paper tissue product and a method of making a one-ply paper product combining high strength and softness along with low sidedness. The paper tissue product exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross directional strength of at least 200 grams per 3 inches. In stratification tissues, these properties are obtained by control of stratification, particu- lady, chemical stratification and stratification of furnish when appropriate. The tissue has a sidedness parameter value of less than 0.3, preferably, about 0.15 to about less than 0.225. In homogenous tissue, these properties are obtained by adding a strength enhancing agent to separate furnish sources prior to the furnish sources being combined, and further, optionally adding the softener to the nascent web.
