摘要:
The present invention provides a method and apparatus for increasing the vector rate of an integrated circuit test system and simplifying the wiring of the tester to the device under test. The tester incorporates circuitry that allows the CPU to remap assignments of tester channels in the CPU address space during testing.

An electronic circuit tester (e.g., for testing integrated circuit wafers or packaged integrated circuits) is provided. The tester is preferably based on a relatively inexpensive computer system such as a personal computer and includes at least one high-precision clock circuit that is programmable with respect to frequency and number of clock pulses. The high-precision clock circuit is connectable to the circuit being tested to permit certain timing-critical tests to be performed, even though a large number of other data channels in the tester are controlled by a relatively low speed clock circuit. The tester also includes analog circuitry that can be programmed to provide various analog signals suitable for performing parametric testing on an electronic device under test.

Computer-assisted procedure (501/502) to communicate data in a transportation system (90) that physically transports objects (800) from first to second locations (10, 20). The objects (800) have write/read memory tags (300). Prior to communicating data is separated into meta-data M and content-data C. Communicated are: C on the tags (300), M through a computer network, and type-data T (representing M) on the tags. System computers (901, 902, 900) perform complementary methods for forwarding (501) and retrieving (502). To forward (501) data from the first location (10), a first computer (901) queries (510) an exchange computer (901) with M for T according to a predefined T-to-M table, writes T to the tags (300), and writes C to the tags (300). To retrieve (502) data at the second location (20) where the objects arrive, a second computer (902) reads T from the (300), queries (550) the exchange computer (900) with T for M according to the same table, and reads (560) C from the tags (300).
摘要:
An auto-identification system is described that includes a plurality of distributed auto-id nodes that are operable to track physical objects as they move through an operation of an enterprise, such as, for example, a supply chain network or a sales network. The auto-id nodes are distributed across sites of the network, and are in communication with enterprise application systems and/or data acquisition systems such as RFID readers or sensor devices. By focusing on their respective sites, the auto-id nodes minimize the amount of data tracked by their respective enterprise applications. Further, the auto-id nodes include rules governing operations on the physical object(s). When an auto-id node receives information regarding a tracking event experienced by the physical object, then the rules may be executed to access known data regarding the physical object, and thereby determine whether the tracking event matches an event that was expected to occur as a result of the operation of the enterprise.

A Wireless bridge conjoins two previously incompatible technologies within a single device to leverage the strengths of each. The Wireless bridge marries the Personal Area Network (PAN) technology of Bluetooth as described in Bluetooth Specification Version 1.0B with the Wireless Local Area Network (WLAN) technology described in the IEEE802.11a specification to provide a wireless system level solution for peripheral devices to provide Internet service interactions. The invention brings together in a single working device implementations of these technologies so they do not interfere or disrupt the operation of each other and instead provide a seamless transition of a Bluetooth connection to Wireless Local Area Network/Internet connection. From the Wireless Local Area Network perspective the inventive wireless bridge extension allows a Bluetooth-enabled device to roam from one Wireless Access Point (bridge) to the next without losing its back end connection. The invention takes into account the minimum separation and shielding required of these potentially conflicting technologies to inter-operate.
摘要:
Systems, methods and computer program products for generic device integration within an auto-id system. The system includes an auto-id node operable to collect data emitted by one or more automatic data acquisition devices, process the data, and make the data available to one or more enterprise applications, user interfaces, or other auto-id nodes. The auto-id node includes a device integration layer that is operable to handle communication between the auto-id node and different types of automatic data acquisition devices, device controllers, or device management systems.
摘要:
A reconfigurable modular interface system for an integrated and standardized weapons system is disclosed. An upper accessory mount is provided that includes one interface for mounting to the desired primary mounting component, such as a firearm. The upper accessory mount further includes a second interface along its bottom edge for attaching accessories thereto. Accessories to be mounted into the modular interface system may either include mating formations that are provided as integrated OEM parts or through the use of retrofit adapter panels mounted to the secondary device.

A method of evaluating out of stock conditions includes determining a minimum provable stock level relying upon RFID and non-RFID information sources.
摘要:
A current state of an item being tracked by an item-tracking system may be determined using prior state information about the item. To ensure proper temporal order of the state information, software events triggered by physical events associated with the item are received from a reader at an event interpretation system. A database or queue within the event interpretation system holds the software events for a delay time determined by a maximum transmission delay time of the software events. A sorter within the event interpretation system orders the software events relative to one another so as to correspond to an order of the physical events. An association model of the event interpretation system may determine state information related to the item for storage in a state information database. Accordingly, system exceptions in the item tracking system may be reduced, and an accuracy and reliability of the system may be improved.
