A valve assembly to dispense fluid from fluid containers including a member that is rotatably slideable in a tube between open and closed positions. The valve assembly utilizes sealing beads to provide seals so that fluid cannot be dispensed from the assembly when the assembly is in the closed position. The valve assembly also includes a tamper evident indicator to show a user whether or not the valve assembly has been previously actuated. The tamper evident indicator may include a tab that is broken when the valve assembly is first actuated. The tamper evident indicator may also include a skirt that either detaches from a knob or fractures when the valve assembly is first actuated.

A System and Method for Person or Object Position Location Utilizing Impulse Radio, comprising a plurality of reference impulse radios; an object or person to be tracked having a mobile impulse radio associated therewith; an architecture with an associated positioning algorithm associated with said plurality of impulse radio reference radios and said mobile impulse radio; and display means for displaying the position of the person or object whose position is to be determined.
摘要:
A conserved inner-core oligosaccharide epitope expressed on the lipopolysaccharide (LPS) of a range of disease causing pathogenic bacterial isolates, including Actinobacillus pleuropneumoniae (Ap), Mannheimia haemolytica (Mh) and Pasteurella multocida (Pm), is disclosed. Construction of a mutant bacterial strain exclusively expressing the conserved inner core OS epitope as a terminally exposed structure has allowed the identification, production and isolation of an inner core LPS which is common to all three organisms. Further provided are associated vaccines, antibodies raised against the conserved LPS inner core and glycoconjugates comprising the LPS inner core linked to an immunogenic carrier.
摘要:
A system and method for highly selective intrusion detection using a sparse array of time modulated ultra wideband (TM-UWB) radars. Two or more TM-UWB radars are arranged in a sparse array around the perimeter of a building. Each TM-UWB radar transmits ultra wideband pulses that illuminate the building and the surrounding area. Signal return data is processed to determine, among other things, whether an alarm condition has been triggered. High resolution radar images are formed that give an accurate picture of the inside of the building and the surrounding area. This image is used to detect motion in a highly selective manner and to track moving objects within the building and the surrounding area. Motion can be distinguished based on criteria appropriate to the environment in which the intrusion detection system operates.
摘要:
An ultra wideband radar system for detecting objects where at least one of the radar system or the object is moving. The radar may be scanned in at least one dimension, which may include angle or range. The system includes a scan combiner that combines scan information in accordance with a trajectory characteristic of a moving object and/or of a moving platform on which the radar resides. Scans may be combined by integration or filtering. A fast calculation method is described wherein the scans are combined into subsets and subsets are shifted in accordance with the trajectory characteristics before further combination. The scan information is combined in accordance with trajectory characteristics to enhance the object signal to noise. Further features are described wherein the scan information is combined according to a family of candidate trajectories and/or object positions.

摘要:
A vehicle engine throttle and brake hand control mechanism having a hand operated input lever movable in one plane to drive a push-pull cable output member axially to control movements of the engine throttle while permitting unemcumbered actuation of the engine throttle by the accelerator pedal, and movable in another plane perpendicular to the first plane to independently drive a brake actuating push rod to control the vehicle brakes, the input lever also being movable to concurrently control the engine throttle and the vehicle brakes.
摘要:
A multifunctional device is disclosed for facilitating plant growth by shining a solar-powered light over plants, and can provide other functions. The multifunctional device comprises a center post, a ground stake, and solar panels. The center post telescopically expands and retracts. The ground stake tapers to a point on one end and can be secured in the ground. Further, the solar panels fold down against the center post for storage, unfold perpendicular to the center post, and are locked in place when in use via a locking collar. The solar panels comprise an underside and a topside, with solar cells secured to the topside and lights secured to the underside. The solar cells absorb sunlight, and turn the sunlight into electrical energy which is used to charge the solar batteries housed in the center post. The solar batteries power the lights located on the solar panels.
