Abstract: A patient support apparatus includes a frame having a first portion that is movable between a raised position and a lowered position to change an elevation at which a person is supported above a floor. Castors are coupled to the frame and are configured to rest upon the floor. An actuator is movable between a brake position in which at least one castor of the castors is braked and a release position in which the at least one castor is released. As the first portion of the frame is moved to the lowered position, the first portion automatically engages the actuator and moves the actuator to the brake position thereby to automatically brake the at least one castor.

Abstract: A patient support apparatus includes a patient support frame for supporting a patient support deck, the patient support frame having two sides extending between a head end and a foot end, and a support assembly for supporting the patient support frame and moving it relative to a floor surface. The support assembly comprises two leg assemblies pivotally coupled at their first upper end portions to the patient support frame and coupled at their lower end portion to floor engaging means. The sides of the patient support frame each comprise inverted substantially U-shaped channel elements having a substantially continuous upper surface, two substantially continuous side surfaces connected at their top edges to the upper surface, and a downward facing opening between the bottom edges of the two side surfaces.

Abstract: The invention relates to a method which is used in the computer-supported design of a physical object, preferably for tolerance planning or for defining a clamping and securing concept, and which automatically determines effects of definitions for a first reference element on a first partial object of a physical object. In the inventive method, target objects for a first reference element on a first partial object of the physical object are automatically searched for. In this context, a target object is a partial object which occurs after the first partial object in the assembly sequence and holds and/or secures the first partial object in the first reference element. Refinements of the invention provide for various reference elements to be compared, or for further reference elements to be generated automatically.

Abstract: When a physical object with partial objects and design elements is designed, a plurality of design states are typically passed through. The invention relates to a method for automatically selecting further partial objects of a physical object whose designs are affected by differences between two design states of a first partial object of the physical object. In this context, the differences between the design states for a design element are determined. Then, the reference partial objects for the first design element are determined in the first and second design states and the differences between these two sets of reference partial objects are determined. The method is preferably applied for tolerance planning and/or for defining the clamping and securing concept, for example for the body of a motor vehicle and for the devices for designing the body.

Abstract: A method and a communications device are described, comprising a radio telephone (5) with connected antenna path (1) which can be used to locate precisely a defective area (F) in the antenna path (1) in order to be able to repair the antenna path (1) in a selective fashion. For this purpose, initially a wave with a starting frequency (f0) is coupled into the antenna path (1), and the amplitude of the standing wave at an angular position is measured. Then, the frequency of the wave is increased until a corresponding amplitude is detected at the same angular position. From the frequencies present then and from a reading (n) which indicates how often the corresponding amplitude has been obtained, the fault interval (Ed) between the detector (18) and defective area (F) is then calculated.

Abstract: In order to inspect at least one antenna branch (A1, A2, . . . An), in particular in a vehicle, a power level to be radiated is initially fed into the antenna branch, after which a power level which is reflected in the antenna branch is sensed. Then, a relationship is formed between the fed-in power level and the reflected power level in order to obtain a quality signal indicating the quality of the antenna branch. This procedure can be carried out successively when there are a plurality of antenna branches, in order to select, as a function of the respective quality signal, that antenna branch at which the reflected power level is lowest. In this way, on the one hand, it is possible to check the matching of the antenna branches while, on the other hand, it is possible to ensure that, for example when specific antenna branches are damaged, it is always possible to find other antenna branches for satisfactory communication.
