An impact damper for deceleration of a vehicle impacting on all obstacle by hydraulic damping forces and gas spring forces includes at least inner and outer pipes telescopically displaceable one inside the other and defining an annular space therebetween with a base closing one end of the inner pipe. A dividing piston is sealingly guided in the inner pipe. The inner pipe, the base, and the dividing piston define a gas space which holds gas under pressure. The inner pipe further defines a first liquid space separated from the gas space by the dividing piston. An intermediate wall is fastened to the inner pipe and includes a throttle opening therethrough connecting a second liquid space to the first liquid space. The annular space between the first and second pipes has one end sealed to the atmosphere and another end sealed by the intermediate wall. The annular space is connected to the second liquid space by a flow connection having a valve.

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.

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.
摘要:
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.

摘要:
A planar array antenna for radar sensors includes: a plurality of base antenna elements situated in a common plane on a printed circuit board; and additional antenna elements, which are situated in an offset plane, in each case over one of the base antenna elements. Each additional antenna element is situated individually on an associated carrier, and the printed circuit board is equipped with the individual carriers.
摘要:
An antenna arrangement for vehicle-to-vehicle communication includes at least two antenna transmitters each having a unidirectional directional diagram. The antenna transmitters are positioned in such a manner that a combination of the unidirectional directional diagrams of the antenna transmitters generates a largely omnidirectional directional diagram by way of a method for transmitting and/or receiving.
