Abstract:
Line Replaceable Unit (LRU) health nodes (10) are provided, as are methods for determining maintenance actions with respect to LRU health nodes. In one embodiment, the LRU health node includes a passive Radio Frequency identification (RFID) module (28) having an RFID memory (50) and an RFID antenna (52) coupled thereto. The LRU health node further includes a mass storage memory (30), a sensor (34, 36) configured to monitor an operational parameter of an LRU (12, 14) and generate a corresponding output signal, and a health node controller (26) operably coupled to the RFID module, to the mass storage memory, and to the sensor. The health node controller is configured to: (i) record the output signal generated by the sensor in the mass storage memory as time-phased sensor data, (ii) derive health summary data from the time-phased sensor data, and (iii) store the health summary data in the RFID memory.
Abstract:
Various embodiments of a wirelessly detectable object to be used in medical procedures are provided. One example wirelessly detectable object includes a radio frequency identification (RFID) transponder that, when interrogated, wirelessly returns a first response signal that contains identification information associated with a surgical object. The wirelessly detectable object further includes a presence transponder that, when interrogated, wirelessly returns a second response signal that does not contain identification information. The presence transponder is received and freely movable within a pouch. The presence transponder is independently movable with respect to the RFID transponder. Another example wirelessly detectable object includes at least one active antenna element and at least one passive antenna element that together operate as a directional antenna.

Abstract:
The present technology relates to a communication device, a communication method, an integrated circuit, and an electronic instrument, which are capable of reducing a manufacturing cost of a communication device having both functions of an RF tag and reader/writer or an electronic instrument equipped with the communication device. A transmitting circuit transmits transmission data to a communication target by performing load modulation of changing an impedance of an antenna unit according to the transmission data using a first carrier generated in the antenna unit when the transmitting circuit operates in a first operation mode in which the transmitting circuit operates as an RFID reader/writer is performed, and the transmitting circuit transmits the transmission data to the RFID reader/writer by performing the load modulation of changing the impedance of the antenna unit according to the transmission data using a second carrier received by the antenna unit when the transmitting circuit operates in a second operation mode in which the transmitting circuit operates as a communication target of the RFID reader/writer is performed. For example, the present technology can be applied to a communication device having both functions of a reader/writer and an RF tag or an electronic instrument equipped with the communication device.
Abstract:
A method of reading RFID tags may include providing a device that can read barcodes and RFID tags. The barcodes may be attached to an object and respectively having a predetermined sequential read order. While reading the barcodes in the predetermined sequential read order, outputting an interrogation signal to RFID tags so that the RFID tags can be read while the barcode reader moves to sequentially read the barcodes in the predetermined sequential order.
Abstract:
An automated dispensing apparatus for the controlled dispensing of articles provided with associated RFID tags, comprises hatches (14) for opening article entry/exit zones and an internal motor-driven store (13) with shelves (15) divided up into a plurality of compartments (16) and intended to receive articles to be dispensed, upon command, through the hatches (14). The control unit (18) provided with a memory (30) intended to memorize the contents of the store and is connected to the store (13) in order to be able to operate the store so as to bring a selected compartment (16) into loading and unloading positions and allow the loading/unloading of an article inside the compartment. Inside the apparatus there is at least one RFID tag reader element (31, 131) which is connected to the control unit (18) and the control unit (18) is adapted to receive from the reader element (31, 131) data read by the reader element from an RFID tag and associate said data in the memory (30) with the compartment (16) which at that moment is close to the reader element (31, 131). A method for controlling the apparatus is also described.
Abstract:
One embodiment of a method of interrogating a sensor to detect the presence of moisture on an occupant support comprises the steps of A) providing a moisture responsive sensor in a surveillance zone of the occupant support, the sensor being tuned to a center frequency; B) exciting the sensor with an electromagnetic signal having a frequency approximately equal to the center frequency; C) monitoring for a center frequency response from the sensor; D) comparing the center frequency response to an expected center frequency response; and E) if the center frequency response compares favorably to an expected center frequency response, issuing a first output consistent with the favorable comparison.
