摘要:
Protocols, systems, and methods are disclosed for two or more RFID tags to communicate with each other using direct connections, wherein the two or more RFID tags are configured to mate and directly exchange identification information. A disclosed method includes detecting that a first RFID tag is connected to a second RFID tag. A first message comprising a first tag identification is sent directly from the first RFID tag to the second RFID tag, and the first RFID tag receives a first acknowledgement from the second RFID tag if the first tag identification was correctly received. A second message comprising a second tag identification may be sent directly from the second RFID tag to the first RFID tag and a second acknowledgement may be received from the first RFID tag if the second tag identification was correctly received
摘要:
Protocols, systems, and methods are disclosed for at least one RFID tag and a device, to communicate with each other using direct connections, wherein the at least one RFID tag and the device are configured to mate and directly exchange identification information. A message comprising a tag identification may be sent directly from the RFID tag to the device, and the RFID tag may receive a first acknowledgement from the device if the first tag identification was correctly received. A connection may be detected between the RFID tag and the device prior to directly exchanging information. The exchange of information may include sending data from the device to the RFID tag.
摘要:
Protocols, systems, and methods are disclosed for two or more RFID tags to communicate with each other and a device using direct connections. A disclosed system includes a first RFID tag, a second RFID tag, and a device. The first and second RFID tags are configured to mate to each other and directly exchange information. The second RFID tag is further configured to directly exchange information with the device such that information received directly at the second RFID tag from the first RFID tag may then be directly exchanged with the device. The first RFID tag may send a first tag identification directly from the first RFID tag to the second RFID tag. The second RFID tag may then send a first acknowledgement to the first RFID tag if the first tag identification was correctlyreceived by the second RFID tag.

摘要:
Multi-mode optical fiber apparatuses, multi-mode optical fibers, and related methods for improving fiber link bandwidth are disclosed. One or more end structures can be disposed on an optical fiber end of a multi-mode optical fiber to improve link bandwidth by reducing and/or eliminating modal dispersion. Modal dispersion can be caused by higher-order modes or modes in an optical fiber being excited by received light. Modal dispersion can limit the bandwidth of an optical fiber link. In certain embodiments, end structures for multi-mode optical fibers are disclosed for reducing the launch angle of light in an optical fiber to reduce modal dispersion. In other embodiments, end structures for multi-mode optical fibers are disclosed for reducing or eliminating coupling astigmatism. In other embodiments, end structures for multi-mode optical fibers are disclosed for directing higher order modes or groups away from an optical detector to reduce or eliminate modal dispersion. In one embodiment, a prism structure is disposed on the source end of the multi-mode optical fiber. In other embodiments a convex profile lens is disposed at the source and detector ends of the fiber.
