Patent number: 5286908Abstract: The disclosed invention provides a music-controlled graphic interface for closely binding musical and graphical information. The invention comprises a digital instrument interface, a computer device for translating digital musical sequences into graphical display information, and one or more displays for presenting the graphical information. Digital musical information is used to access graphical information. The accessing of the graphical information can be accomplished using the digital musical information as an index to a stored look-up table of video/graphic data. Alternatively, the musical information can serve as an input into an algorithm to calculate the video data in real time. The invention can also proceed in the backwards direction. Changing graphical data can be used to access musical or other sound information, to create musical sounds that match closely a changing displayed image. The invention allows accurate and rapid synchronization of sound and image, especially in computer animation.Type: GrantFiled: April 30, 1991Date of Patent: February 15, 1994Inventor: Stanley Jungleib

Patent number: 5279346Abstract: A stackable, non-skid snow chain ramp is disclosed for use in the installation of tire chains on both snowy and icy surfaces. The tire ramp is designed with a grooved top and bottom surface and is operated by laying a pair of the ramps in parallel, spaced the distance equal to the separation of the automobile wheels. Tire chains are then laid over the spaced ramps with the cross links of the chains inserted into spaced chain grooves. The tire is then driven up onto the ramp and brought to rest against a tire block and positioned within a wheel well constructed in the ramp. The chains are then wrapped around the tires and connected in a traditional manner. The bottom surface of the ramps contain a combination of grooves and replaceable spikes for use in both snow and icy surface conditions. The disclosed ramps are designed to permit symmetrical stacking for easy storage and conveyance.Type: GrantFiled: May 21, 1992Date of Patent: January 18, 1994Inventor: Keith Summey

Patent number: 5222023Abstract: An improved method for transitioning a spacecraft from a thruster (5) controlled, station keeping mode to an operational, on-orbit mode, in which attitude control is maintained using internal momentum wheels (3). The method first utilizes a thruster compensation technique to supplement the conventional transition mode control system. This compensation uses empirical thruster data to derate thruster (5) efficiency for extremely short pulse durations necessarily used in transition mode operation. Secondly, a three step deadbeat thruster (5) sequence is employed in which a first pulse linearizes spacecraft (1) motion prior to orienting and stopping nutation. This linearization provides improved accuracy in computing and shortens the waiting time for subsequent thruster (5) firings.Type: GrantFiled: April 2, 1991Date of Patent: June 22, 1993Assignee: Space Systems/Loral, Inc.Inventors: Tung Y. Liu, Scott W. Tilley

Patent number: 5166692Abstract: An adaptive RADAR environmental signal filter (1) is described which selectively preprocesses RF RADAR input data prior to the data's utilization by a processor (8). The filter (1) consists of an array of parallel discriminator cells (165) which compare incoming RF RADAR data to a window parameterized by predetermined threshold values. The array of discriminator outputs are networked through combinational logic (59) in order to provide an output correlation signal (63) to an external processor (8). A discriminator enable latch (55) synchronizes the discriminator outputs as the outputs pass through the combinational logic (59).Type: GrantFiled: August 19, 1991Date of Patent: November 24, 1992Assignee: Loral Aerospace Corp.Inventors: Donald C.

Patent number: 5140352Abstract: A method and apparatus are disclosed for converting the 35 mm image from a conventional fundus camera into a size suitable for recording by a conventional solid state CCD module. The CCD camera connects to the fundus camera using a bayonet attachment. The aerial image created by the fundus camera is received and transmitted through the CCD camera along a folded mirror optical path, and is reduced and aligned for detection by the CCD module. The optical path contains a pair of adjustable mirrors to allow compensation for variations in the focal lengths between various fundus cameras. An articulating mirror may be included to enable the user to pan across the aerial image while recording segmented views for reconstruction by an external computer into a composite, high resolution image.Type: GrantFiled: October 31, 1990Date of Patent: August 18, 1992Assignee: Occipital, Inc.Inventors: Robert D.

Patent number: 5114227Abstract: A laser targeting system comprises an airborne reconnaissance platform (1) disposed to conduct surveillance of enemy air, ground, and/or sea targets (5). The surveillance means (11) can be some combination of FLIR, laser, or radar devices. Platform (1) may be manned or may be a remote pilotless vehicle commanded by a ground control station (9). Several friendly units (2) are capable of firing weapons at the enemy targets (5). The friendly units (2) desire real-time targeting information, such as video images, range, and coordinates. The friendly units (2) typically desire information for only certain types of targets (5) or for those within proximate geographical areas. These selective requests are sent via a laser uplink (28) to platform (1), which determines the direction from which the request came by a direction determining means (17), and selectively processes the request by means of a decoder/controller (16).Type: GrantFiled: May 14, 1987Date of Patent: May 19, 1992Assignee: Loral Aerospace Corp.Inventor: William C.
