Abstract: The primary function of the Bootstrap invention is to provide a flexible elastic woven band material that has a high heat resistant that connects to the bottom of the person's boots to their pants. The invention also provides a means to reduce the thermal heat from traveling between the person's pants by eliminating the separation distance between the pants and the boots. The invention is simple to install and provides a high degree of flexibility to insure that it maintains operation while connected to the person's boots and pants. The invention is either wrapped around the outside of the bottom of the person's boot or the inside the person's boot like a stirrup. The invention has multiple applications for people such as, firefighter bunker pants, commercial and military situations where the boots and pants need to be a close as possible during heat related and other situations.

Abstract: A method of implementing a Communication Barring, CB, service within an IP Multimedia Subsystem, IMS, network in respect of an ongoing IMS session or an IMS session in early session phase. The method comprises, at an Application Sever, AS, within the IMS network, parsing SIP messages relating to the session to detect an attempt to add one or more media streams to the session. CB service rules are applied to determine the allowability of the media stream(s) being added. If the media stream(s) being added is (are) not allowed, action is taken to prevent its addition, and otherwise allowing the media stream addition to proceed.

Abstract: Methods for the production and isolation of a monomer from a biopolymer are described. The method includes extracting a biopolymer from a biopolymer source and depolymerizing the biopolymer into a monomer. Methods for the production and isolation of a monomer from corn lignin are also described. The method includes extracting corn lignin from corn biomass and depolymerizing the corn lignin into a monomer.

Abstract: A wiper system for clearing a surface of a dome includes a plurality of wiper blades that are configured to move around a circumference of the dome. Rotation of the wiper blades in a first direction around the circumference of the dome deploys the wiper blades into an upright position and rotation of the wiper blades in a second direction opposite the first direction stows the wiper blades into a collapsed position.

Abstract: An array antenna for radar sensors has a supply line, a plurality of antenna elements each connected to the supply line via a feed line, and circuit elements for distributing power to the antenna elements, in which the supply line is made reflective at one end and the circuit elements for power distribution are situated exclusively in the feed lines.

Abstract: A radar sensor including an antenna array having multiple antenna elements situated next to one another and at least one feeding point at an outer antenna element. The antenna elements are connected in series via delay lines. The radar sensor has at least two transmitting and receiving units which are each suitable for generating and evaluating a radar signal at a predefined frequency. The at least two transmitting and receiving units are connected to a feeding point of the antenna array. The frequencies of the radar signals of the at least two transmitting and receiving units are predefinable independently of one another.

Abstract: A radome for a radar sensor in a motor vehicle. The radome includes a first region, which is permeable to at least one specific type of electromagnetic waves, in particular radar waves, and a second region, which includes a shield, so that the second region is impermeable to the specific type of electromagnetic waves. Also, a radar sensor is described.

Abstract: A circuit for connecting lower AC voltage-rated AC-DC power supplies with higher voltage power sources. A power line matching transformer connecting the source to the power supplies needs only to support the self-dissipation and output current mismatch between supplies. The circuit can also protect the line matching transformer from overheating in various fault scenarios.

Abstract: An antenna has an antenna body having a plurality of first antenna elements, which are disposed along a first straight line. A hollow conductor, which extends between the first antenna elements, is disposed in the antenna body. The first antenna elements are developed as openings running between the hollow conductor and a surface of the antenna body. The antenna is designed to radiate a signal in a spatial direction that is a function of a frequency of the signal. The antenna body has an electrically insulating material that is coated with a conductive material.

Abstract: A radar sensor for motor vehicles, having a source of radar radiation and a lens, which is situated in front of the source, is made of a material that refracts radar radiation and has a convex surface on at least one side, wherein the convex surface has a greater curvature in elevation than in azimuth.

Abstract: A telescoping dip tube assembly having a first tube which telescopes within a second tube. The exterior surface of the first tube has a first tube stop ring extending outwardly from its exterior surface adjacent its bottom end. The second tube has a second tube stop ring which extends inwardly from its interior surface. When the second tube is lowered over the first tube, the bottom surface of the second tube stop ring engages the top surface of the first tube stop ring, thereby preventing the second tube from separating from the first tube. This arrangement provides the advantage of a telescoping dip tube assembly that is strong and durable and prevents the second tube from falling into a tanker while being loaded.
