Abstract: A cot includes a cloth having horizontal poles inserted into both ends thereof; a plurality of lateral support bars for supporting a load in contact with the ground, at least one of the plurality of lateral support bars comprising a support bar first portion pivotally connected to a support bar second portion such that the support bar has a first, locked position and a second, unlocked position; and a plurality of connection bars connected to both ends of each support bar and respectively having clips at terminals thereof to receive the horizontal poles.

Abstract: A step apparatus that removably couples to a door latch element of a door well of a vehicle is disclosed. The step apparatus can include a load-supporting step structure, an elongated support element, and an axle structure rotatably coupling the load-supporting step structure to the elongated support element. The elongated support element can include a hook-shaped element configured to removably couple to the door latch element of the door well of a vehicle. The load-supporting step structure is configured to support the weight of a person when standing on the load-supporting step structure while the step apparatus is removably coupled to the door latch element, enabling the person to reach the roof of the vehicle.

Abstract: A connecting device (4) for connecting a target object (1) to a towing vehicle (3) for functionally testing a driver assistance system of a test vehicle (7) for test driving, includes two deformable pressurizable hoses that extend in a longitudinal direction (e.g. from the towing vehicle to the target object) and that are connected to each other transversely to the longitudinal direction. A test arrangement includes the towing vehicle connected to the target object by the connecting device.

Abstract: A device and a method provide for the non-destructive simulation or reproduction of driving situations involving collisions and/or near-collisions between a test vehicle and a target object, while testing driver assistance systems or anticipatory vehicle sensor systems of the test vehicle. The target object is moved along a guide rope, for example by a drive rope. If a load exceeds a threshold value during a collision of the test vehicle with the target object, then the target object decouples from the guide rope.

Abstract: The invention relates to a device (4) for connecting a target object (1) to a towing vehicle (3) for functionally testing a driver assistance system of a test vehicle (7) for test driving, especially for near-collision and collision test driving, and a test arrangement wherein said device is used.

Abstract: A cushion or bathtub mat includes a pair of contiguous layers each with a repeating pattern of upstanding straight walls forming upstanding cells with upstanding openings between the walls. The repeating patterns of the pair of layers are laterally offset with respect to one another to form a dual layer offset honeycomb. The walls are flexible to buckle into the openings of the cells under a compressive force, and resilient to return to an original upstanding orientation, while having at least a strength to be self-supporting.

Abstract: The invention is directed to polyurethane foams which are flotation resistant with sufficient strength and density to provide stability and inhibit erosion at pipeline trench sites, and other uses, wherein at least 50% of the foam is open cell and has a density of approximately 1.3 lbs/ft3 to 3.5 lbs/ft3.

Abstract: A method for producing a rigid, closed-cell polyurethane foam having a free-rise density of from about 1.3 lbs/ft.3 to about 4 lbs/ft.3 and exhibiting a shrinkage of less than 10%, comprises mixing together an isocyanate, at least one alkyl alkanoate blowing agent and at least one polyol having a hydroxyl number of from about 150 to about 800 and being selected from the group consisting of polyalkoxylated amines, polyalkoxylated ethers, and polyester polyols, to form a reaction mixture that is curable to produce such foam.

Abstract: The invention is directed to methods of preparing compositions used to manufacture polyurethane foams. The invention provides methods for making compositions used to make polyurethane foams that include amine catalysts, but formulated such that catalytic potency is not diminished over time before the forming of a foam.

Abstract: A method for protecting the digital output signal of a security module, comprising the steps of: receiving a scrambled digital signal from a source external to said security module, recovering at least one transport scramble control flag from the scrambled digital signal, descrambling said received scrambled signal to generate a descrambled signal, monitoring the at least one transport scramble control flag, generating a scrambling key in response to said monitored at least one transport scramble control flag, and scrambling said descrambled signal using said scrambling key to generate a re-scrambled signal. The present invention also includes a conditional access system comprising a host device and a security device coupled to the host device, such that the security device includes at least one transport scramble control flag modification circuit. By monitoring the transport scramble control flag as content passes through the security module, protection of the content can be securely maintained.
