    摘要: Disclosed are an object locator system, a method and a program storage device. In the embodiments, radio frequency identification (RFID) tags are on objects within a defined area and each RFID tag can be activated by an RF activation signal. When a request (e.g., a verbal or keyed-in request) to locate a specific object is received from a specific user, the required permission to locate the object is verified and, optionally, the identity of the specific user is authenticated. Once the required permission is verified and the identity of the specific user is authenticated, one of three RFID readers transmits an RF activation signal. RF response signals received back at the three RFID readers from the specific object's RFID tag are used to triangulate the position of the specific object. Once determined, the position is communicated (e.g., by map display, verbal message, or text message) to the specific user.

    摘要: Fuse macros of identical number of pages are serially arranged to form the same number of fusebay pages each having a length equal to the sum of the respective fuse macro page lengths. Each fuse macro has an enable latch configured to allow activation of one fuse macro at a time. A fusebay control device connected to a repair register may store data in and retrieve data from the fusebay. Next available fuse location is determined in programming mode so that data from a next repair pass may start where the last data ended.

    摘要: The invention provides a circuit that can observe data within shift registers without altering the data. The circuit includes selectors connected to the inputs and outputs of the shift registers. The selectors selectively connect the input with the output of a selected shift register to form a wiring loop for the selected shift register. A control device connected to the wiring loop uses the wiring loop to cause the data to be continually transferred from the output of the selected shift register to the input of the selected shift register and back through the selected shift register in a circular manner. The control device includes a counter used for determining the length of a selected shift register and a set of registers to store, for future use when rotating data in the shift registers, the length of each shift register. The control device also includes a data output accessible from outside the circuit. An observation wire is connected to the wiring loop, and the data passes from the wiring loop to the control device through the observation wire. The control device outputs data appearing on the wiring loop as the data is circulated through the selected shift register to permit data within the selected shift register to be observed outside the circuit without altering the data within the selected shift register.
