摘要:
An improved computer system bus is disclosed that transitions between addressed data transfers and handshake data transfers on the fly and that performs burst within dynamic data sizing during a data transfer sequence without prematurely terminating the sequence and that changes between synchronous and asynchronous data transfer sequences on the fly. These capabilities are accomplished by modifying the function of bus signal lines depending upon the type of transfer sequence undertaken. On the fly transition between addressed data transfer and handshake data transfer is accomplished by providing a set of DMA acknowledge signals and modifying their function according to the type of data transfer sequence underway. Burst within dynamic data sizing during a sequence is performed by taking advantage of burst transfer capabilities of the slave device, and the capability of the master device to modify data width on the fly. If the slave supports burst transfer, the bus master proceeds with a burst transfer sequence for the remaining portions of the data while shifting the data to accommodate the data width limitation of the slave device. On the fly transition between a synchronous transfer sequence and an asynchronous transfer sequence is accomplished by modifying the timing of bus acknowledge signals.

A method is disclosed whereby an inexpensive integrated circuit is provided for use in high volume electronic consumer devices of different makes, wherein each different make must perform a different special function. A common function required in all the different makes is realized in a substantially non-customizable portion. A dense mask-programmable portion is provided for realizing a special function. Interface circuitry is provided that enables an external FPGA to perform the special function at system operating speeds during system development. After system development, the circuitry implemented in the external FPGA is technology-mapped to the mask-programmable portion. A single mask is fashioned such that versions of the integrated circuit are produced with their mask-programmable portions customized to perform the special function. I/O terminals that were used to couple to the external FPGA during system development are usable during normal operation to provide system board access to circuitry within the mask-programmable portion.

An intravenous pole clamp contains a locking mechanism which employs a spring clutch. The clamp body has an attachment for a medical device and a chamber for receiving an I-V pole. A threaded stud is rotated inwardly to clamp the I-V pole. A spring having one fixed end and one free end is threaded onto the shaft of the threaded stud. A locking mechanism allows the free end of the spring to be unrestrained in a locked position. When unlocked, a pin of the locking mechanism slightly unwinds and restrains the free end of the spring freeing the threaded stud to rotate in either an inward or an outward direction. In a locked position, the threaded stud can rotate inwardly but if it is attempted to rotate it outwardly the spring clutches the threaded stud preventing outward rotation.
