Abstract: Suggested are methods and devices for dynamic resource allocation in a multiprocessor computer system with a plurality of components. The method comprises different steps, such as receiving a request for access to a shared resource, wherein after the allocation of the requested shared resource to the requesting unit, a prescribed real-time requirement is to be ensured by the multiprocessor computer system. Based on the operating parameters determined for a design time of the multiprocessor computer system and current operating parameters, future operating parameters to be expected after an allocation of the requested shared resource are determined. If the prescribed real-time requirement operating parameters is to be ensured in the future, the requested resource is allocated to the requesting unit.

Abstract: A method for operating a multiprocessor computer system which has at least two microprocessors, resources which are jointly used by the microprocessors, programs executed on the computer system, and at least one resource manager. The resource manager manages resources which are assigned to said manager and can be adjusted at least in terms of their time response. The resource manager receives and processes reservation requests for reserving desired resources, which reservation requests are transmitted by programs. The reservation requests describe at least the type, scope and time response of the desired resources. The resource manager allocates the respectively desired resources to the requesting program if said resources are available. The resource manager adjusts the time response of the allocated resources according to the time response requested with the reservation request.

Abstract: A method and apparatus for determining contact resistance (107) includes pressing a lead connector (105) to make a first contact with a metallic pad (103) and an isolated contact with an isolated metallic pad (108) located adjacent to metallic pad (103). Once the first and isolated contacts are formed, the method includes flowing electrical current at a predetermined level through the isolated contact. With the aid of a volt meter (110), voltage differential across the isolated contact is measured while the electrical current at the predetermined level is flowing through the isolated contact. The contact resistance (107) of the first contact is determined based on information obtained from the voltage differential measured across the isolated contact and the predetermined level of the electrical current. Furthermore, the contact force created at the first contact is determined based on the contact resistance (107).

Abstract: A remote power measuring device (1) is used to measure the power output of the transmission system (20). The measured power is then transmitted to a controller (5) and used by the controller (5), along with preset calibration data (41) for each power amplifier (3), to determine power output adjustment factors (22). The adjustment factors (22) are then communicated to the appropriate power amplifier (3) to adjust its output.

Abstract: A dry shaving apparatus has a shearing foil, a reciprocable blade member cooperating with the shearing foil, a pressure spring urging the blade member toward the shearing foil and extending with the former in a first direction, a shearing head frame, and an auxiliary frame insertable into the shearing head frame and mounting the shearing foil so that it is convex. The auxiliary frame is fixed to the shearing foil at one longitudinal side of the former and is resiliently yieldable in the first direction. The auxiliary frame is arrested in the shearing head frame at the ends of the former.
