Patent number: 5065805Abstract: A cabinet includes a rigid housing having an opening at the forward side thereof with vertical guide tracks defined at opposite sides of the opening. A roller subassembly is mounted in the upper portion of the housing over the opening and is driven in rotation about a horizontal axis by a motor. A segmented glass curtain made up of contiguous, elongated, parallel glass slats of rectangular configuration closes the opening in the housing. Each glass slat is supported in metal corner brackets interconnected so that adjacent longitudinal edges of adjacent slats are in close proximity, and the slat ends project into the guide tracks. Flexible cables interconnect the corner brackets to maintain the spacial relationship of the slats.

Patent number: 5067014Abstract: An iterative process, implemented by a feedback loop, responds to all the image data in the respective analysis regions of three consecutive frames of a motion picture, to provide, after a plurality of cycles of operation thereof, an accurate estimation of the motion of either one or both of two differently moving patterns defined by the image data of these respective analysis regions. The analysis region of each frame is preferably large, and may occupy the entire frame area of a frame. The type of differently moving patterns include (1) separation by a motion bounty, (2) overlapping transparent surface in motion, (3) "picket fence" motion (4) masking of a small and/or low-contrast pattern by a dominant pattern, and (5) two-component aperture effects. Also, the operation of this iterative process inherently accurately estimates the motion of image data defining a single moving pattern.Type: GrantFiled: December 13, 1990Date of Patent: November 19, 1991Assignee: David Sarnoff Research Center, Inc.Inventors: James R.

Patent number: 5064530Abstract: Fluid reservoirs are often provided with a means by which the severity of fluid contamination may be monitored. One method of checking the condition of the fluid, requires the disassembly or removal of one or more components from the associated reservoir in order to read the monitoring device. Another method is utilized in conjunction with the filtration system of the fluid and an indication is observed when the level of contamination reaches a predetermined point. The present invention provides an apparatus whereby the condition of a fluid may be continually observed without requiring the disassembly or removal of any components attached to the fluid reservoir, regardless of the condition of the fluid.Type: GrantFiled: June 4, 1990Date of Patent: November 12, 1991Assignees: Caterpillar Inc., David A.

Patent number: 5063603Abstract: A time series of successive relatively high-resolution frames of image data, any frame of which may or may not include a graphical representation of one or more predetermined specific members (e.g., particular known persons) of a given generic class (e.g. human beings), is examined in order to recognize the identity of a specific member if that member's image is included in the time series. The frames of image data may be examined in real time at various resolutions, starting with a relatively low resolution, to detect whether some earlier-occurring frame includes any of a group of image features possessed by an image of a member of the given class.Type: GrantFiled: November 6, 1989Date of Patent: November 5, 1991Assignee: David Sarnoff Research Center, Inc.Inventor: Peter J.

Patent number: 5060704Abstract: Suction transfer assembly for a medicament liquid, formed of a vial having a chamber filled with the liquid and an open end closed by a penetrable stopper on which the vial is slidable longitudinally, and an adapter having a front end with a nozzle lockably connectable to a mechanical probe-containing counterpart nozzle of a suction device, e.g. a syringe, a rear end with a hollow needle, and an internal flow path therebetween. The adapter rear end is insertable into the vial open end and fastenable to the stopper for penetrating the stopper by the needle. The adapter front end has a mechanical probe-openable and self-closing check valve in the flow path adjacent the nozzle so that on locking the counterpart nozzle thereto, its probe opens the valve for suction transfer of liquid from the vial to the device and simultaneous compensating vial movement relative to the stopper under external atmospheric pressure to reduce the chamber volume by an amount generally equal to the liquid transferred.Type: GrantFiled: May 25, 1990Date of Patent: October 29, 1991Assignee: David Bull Laboratories Pty.

Patent number: 5043782Abstract: A protection device for an integrated circuit includes short and longer channel length structures, each of which provides a parasitic bipolar transistor, connected between a terminal of the integrated circuit and a source of reference voltage. The short channel length structure has a breakdown voltage greater than the supply voltage for the integrated circuit, and less than the insulator damage threshold of the integrated circuit. The conduction through the short channel length structure after initiation of a transient phenomena causes the longer channel length structure to conduct before the transient exceeds the breakdown voltage of the integrated circuit and the short channel length structure. The longer channel length structure operatges in the "snap-back" conduction mode when the current density exceeds a critical value to conduct away the transient energy.Type: GrantFiled: May 8, 1990Date of Patent: August 27, 1991Assignee: David Sarnoff Research Center, Inc.Inventor: Leslie R. Avery

Patent number: 5038368Abstract: A redundancy circuit that substitutes a redundant circuit element for a corresponding defective circuit element includes a severable fuse link and a redundancy control circuit with an input connected to the severable fuse link and first and second outputs. When the fuse link is intact, the first output of the redundancy control circuit is in a first state and the second output is in a second state. When the fuse link is severed, a momentary signal on power up places the first output in the second state and the second output in the first state. The first output is coupled to the one circuit element and the second output is coupled to the corresponding redundant circuit element. If the one circuit element is defective, it is disabled by severing the fuse link.Type: GrantFiled: February 2, 1990Date of Patent: August 6, 1991Assignee: David Sarnoff Research Center, Inc.Inventor: Swye N.
