Abstract:
A camera shield system includes a vehicle that has a back side. At least one camera is coupled to the back side. The at least one camera may display an area behind the vehicle when the vehicle is backing. Thus, the vehicle may avoid striking an object when backing. At least one cone is provided. The at least one cone is coupled to the back side and the at least one cone is positioned to surround the at least one camera. Thus, the at least one cone inhibits the at least one camera from becoming obstructed with precipitation.

Abstract:
A ceramic hot-gas candle filter having a porous support of filament-wound oxide ceramic yarn at least partially surrounded by a porous refractory oxide ceramic matrix, and a membrane layer on at least one surface thereof. The membrane layer may be on the outer surface, the inner surface, or both the outer and inner surface of the porous support. The membrane layer may be formed of an ordered arrangement of circularly wound, continuous filament oxide ceramic yarn, a ceramic filler material which is less permeable than the filament-wound support structure, or some combination of continuous filament and filler material. A particularly effective membrane layer features circularly wound filament with gaps intentionally placed between adjacent windings, and a filler material of ceramic particulates uniformly distributed throughout the gap region. The filter can withstand thermal cycling during backpulse cleaning and is resistant to chemical degradation at high temperatures.
Abstract:
a method for traversing a plurality of strands between two spaced rows of strand-restraining elements moving together in the same direction in substantially the same plane to form a web is implemented by a plurality of strand transfer members moving in a single closed path spanning the rows of strand-restraining elements so that the members pass between strand-restraining elements on one of the rows and above them on the other row. There is a means provided for moving each strand back and forth across the path into engagement with the strand transfer members and a means for disengaging each strand from each strand transfer member beyond the other row and depositing it as a loop around at least one of the strand-restraining elements.
Abstract:
An adjustable head and shoulder rest is disclosed which is intended for supporting the body while lying face down with the head turned to the right or left at forty five degrees. It is intended as well to support the user's head on an elevated plane while the user is lying on either the right or left side. A head or face rest consisting of two distinctly separate members, one being movable, providing open areas for the eyes, nose and mouth, together with movable right and left shoulder support members permitting adjustment to different body dimensions and allowing proper weight distribution, ease of breathing and body comfort.
Abstract:
Methods and apparatus are provided for analyzing a complex system that includes a number of subsystems. Each subsystem comprises at least one sensor designed to generate sensor data. Sensor data from at least one of the sensors is processed to generate binary evidence of a sensed event, and complex evidence of a sensed event. The complex evidence has more sophisticated mathematical properties than the binary evidence. The complex evidence comprises one or more of: a condition indicator (CI), a health indicator (HI), and a prognostic indicator (PI). A system fault model (SFM) is provided that defines statistical relationships between binary evidence, complex evidence, and an underlying failure mode (FM) that is occurring in the complex system. The binary evidence and the complex evidence are processed to identify failure modes taking place within one or more of the subsystems. Based on the binary evidence and the complex evidence and the SFM, diagnostic conclusions can be generated regarding adverse events that are taking place within the complex system, and prognostic conclusions can be generated regarding adverse events that are predicted to take place within the complex system.
Abstract:
A system for monitoring the health of a component includes a memory configured to store a health management system for evaluating the health of the component. The health management system includes a first prognostic module, a first diagnostic module, a first failure mode module, and a first functional module. A processor is coupled to the memory and configured to retrieve the health management system from the memory; receive a first prognostic indicator associated with the health of the component; determine a first predicted diagnostic indicator based on the prognostic indicator with the prognostic module; determine a first failure mode probability based on the first predicted diagnostic indicator with the diagnostic module; determine a first failure mode vector based on the first failure mode probability with the failure mode module; and generate a first functional output based on the first failure mode vector with the first functional mode module.
Abstract:
A communication terminal including a communication unit, a longitudinal antenna enclosed in a radome, and a pivot connecting the antenna to the unit for pivoting about an axis with an RF connection to the unit. The unit is in a box-shaped enclosure having a front face with a keypad and connected to a rear face by top and bottom faces, and two side faces. One of the unit front and rear faces is non-planar from top to bottom with the spacing between the front and rear faces varying from top to bottom. The spacing between the radome front and rear faces varies to substantially match the varied spacing between the unit front and rear faces so that the radome and unit front and rear faces define a uniform profile when the radome is adjacent one unit side face. The unit top face lies on one side of a first plane and at least one unit side face lies on one side of a second plane perpendicular to the first plane. An L-shaped support secured to the unit supports a pivot shaft defining the pivot axis substantially parallel to both of the planes and spaced on the other side of both of the planes by distances allowing the antenna to pivot through a 270 degrees range. A plurality of detents are spaced about the pivot shaft, and a detent mechanism secured to the antenna engages one of the pivot shaft detents in each of a plurality of pivoted positions. The radome has two shells connected substantially along a plane, with longitudinally spaced ribs supporting the antenna in a position spaced from the shell outer walls.
