Abstract: A biopsy needle guide comprising two tapes fastened together so that the upper tape foils an arch with the other tape (base). The lower side of the base tape is coated with an adhesive material so that the guide may be applied to the surface of the skin of a patient. Both tapes are provided with a series of spaced annular apertures which are arranged in a predetermined pattern, which are formed of a material which is visible on a computer generated tomological display.

Abstract: A method and apparatus for transferring control of a memory bus, providing access to a memory array, from a controller having control of the memory bus to a controller desiring control of the memory bus are described. The method requires generating an access request directed to the controller having control from the controller desiring control, which is then detected by the controller desiring control. A determination is made as to whether the memory bus is being used, by the controller having control, by sampling the row address strobe (#RAS) line. A fast bus transfer sequence is initiated if the memory bus is not in use, the fast transfer sequence transferring control of the memory bus to the controller desiring control after a first time period. Alternatively, a slow bus transfer sequence is initiated, when the memory bus use is over, if the memory bus is in use.
