A method for using a radio frequency identification (RFID) system including a transponder, an antenna, and a reader, the antenna coupled to the reader, the antenna and the reader for transmitting a radio signal to the transponder and for receiving a response radio signal from the transponder, the response radio signal including data from the transponder, the method including: selecting a curtain that limits propagation of the radio signal; and placing the curtain in an area through which the radio signal would otherwise propagate; wherein the curtain includes a plurality of flexible strips transparent to visible light, the long edge of each of the strips is oriented in substantially the vertical direction, more than one strip overlaps a portion of the width of an adjacent strip along the length of the adjacent strip, and the length of each of the strips is substantially greater than the width of each of the strips.
摘要:
A system, method, apparatus, and computer program code for conducting or otherwise facilitating a transaction or request involving a product. A transaction or request involving a product is decomposed or broken down into two or more secondary transactions or requests involving the product. Thus, for an initial transaction, a set of two or more secondary transactions is established that take place instead of the initial transaction. A transaction may involve the purchase or sale of a product at one or more marketplaces. If an initial transaction or request can or is to be conducted within a given period, then some or all of the secondary transactions also may occur within the given time period. Some or all of the secondary transactions or requests may be conducted at the same marketplace or at different marketplaces.

Systems and methods are provided wherein a consumable item parameter is exchanged between a consumable item and a consuming device. According to one embodiment, a consumable item parameter request is transmitted to a device associated with a consumable item, and the consumable item parameter is then received. The device may comprise, for example, the consumable item or a device associated with dispensing the consumable item. The device may also comprise, for example, a device associated with a consumption of the consumable item, a device adapted to control a consumption of the consumable item, or a device that consumes the consumable item.

A system, method, apparatus, and computer program code for notifying at least one entity upon receipt of an item is provided. According to embodiments of the present invention, a determination is made whether an item has been placed in a repository. This determination may be made using any of a number of different types and combinations of sensors. An identification of at least one entity to be notified is then made, and the entity is notified if a determination is made that an item has been placed in the repository.
摘要:
A system produces of an empirical map of wireless communication coverage through a process of combining information from individual clients to produce a map which is then shared by all of the clients. The wireless coverage map aids in maintaining a reliable communications link. The empirical map is generated by combining information from a group of mobile wireless users. The group may consist of a fleet of trucks, taxicabs, government service vehicles, or the customers of a wireless service provider. The mobile vehicles must be equipped with a GPS device or be located by other means such as triangulation. While vehicles are moving, the quality of wireless communication, e.g., signal strength or communication continuity, is recorded for each vehicle as a function of positions. The data from all of the vehicles is combined to produce the empirical map. The empirical map may be maintained at a central site and subsets of the map replicated for individual vehicles. The map may then be used to direct mobile users to sites of superior communications reliability, warn mobile users when they are out of the service area or are about to leave the service area, or to regulate data communications automatically to stop and restart communications as a mobile vehicle passes through a gap in coverage.
摘要:
A mobile navigation system implemented as an embedded system in a vehicle is easy to use, does not detract the driver's attention from the road, and limits the number of choices presented to the user of the navigation system according to a predetermined set of preferences or personalized information. Choices are filtered according to a set of driver preferences, according to the vehicle's geographic position, direction of motion, and the driver's intended itinerary. The itinerary, including intermediate stops, is calculated on an external computing system. The information is downloaded from the computing system to a memory device such as, for example, a smart card. The information is then transferred from the smart card to the embedded vehicle navigation system. In one application of the invention, a kiosk located at a car rental agency may be used to create and store personalized navigation information onto a smart card which the customer then inserts into the vehicle navigation system that is installed in the rental car.

Automated bonding of chips to tape and formation of bonding structures on Tape Automated Bonding (TAB) packaging structures are provided with bonding balls on the ends of beams leads of the TAB tape. Also balltape bonding balls are aligned on stacked TAB sheets and bonded together to form via interconnections through stacked balltape balls in multilayer, electronic packaging structures. Interconnection structures are provided for a universal chip connection laminate which can be applied between a chip and an MLC package. Area TAB tape, which comprises a modification of TAB tape provides balltape TAB connections by means of balltape bonds to areas within the interior of a chip whose leads are bonded in a TAB tape arrangement to the Inner Lead Bonds of the area tape.

This interface permits the testing of high speed semiconductor devices (room-temperature chips) by a Josephson junction sampling device (cryogenic chip) without intolerable loss of resolution. The interface comprises a quartz pass-through plug which includes a planar transmission line interconnecting a first chip station, where the cryogenic chip is mounted, and a second chip station, where the semiconductor chip to be tested is temporarily mounted. The pass-through plug has a cemented long half-cylindrical portion and short half-cylindrical portion. The long portion carries the planar transmission line, the ends of which form the first and second chip mounting stations. The short portion completes the cylinder with the long portion for part of its length, where a seal can be achieved, but does not extend over the chip mounting stations. Sealing is by epoxy cement. The pass-through plug is sealed in place in a flange mounted to the chamber wall. The first chip station, with the cryogenic chip attached, extends into the liquid helium reservoir. The second chip station is in the room temperature environment required for semiconductor operation. Proper semiconductor operating temperature is achieved by a heater wire and control thermocouple in the vicinity of each other and the second chip mounting station. Thermal isolation is maintained by vacuum and seals. Connections for power and control, for test result signals, for temperature control and heating, and for vacuum complete the test apparatus.
