Abstract: Disclosed is a process of determining, at a point during shipment, whether the solid phase refrigerant in a shipment is sufficient to preserve the shipment cargo, which is blood or other biological products, for the remaining shipment period, by: monitoring the temperatures encountered to said point and estimating the temperatures likely to be encountered during the remaining shipment period; determining the likelihood that the remaining refrigerant can maintain the shipment cargo within a specified temperature range during the remaining shipment period; and if the risk that the remaining refrigerant cannot maintain the shipment cargo within said range during the remaining shipment period is above a cut-off level, then taking action to preserve the value of the cargo.

Abstract: There is described a method for adjusting the detection, transmission and/or reception parameters (DET, GTx, GRx) of a radiofrequency reader (10) of an electronic radiofrequency identification system as a function of the ambient electromagnetic noise. This method includes at least one step of measuring, via the radiofrequency reader, the ambient electromagnetic noise level, and a step of adjusting the detection, transmission and/or reception parameters of the radiofrequency reader on the basis of the measured ambient electromagnetic noise level. Preferably, this method further includes a step of measuring the response of a reference transponder (30) placed at least temporarily in the interrogation field of the antenna (20) associated with the radiofrequency reader, this reference transponder (30) having similar characteristics to the characteristics of the transponders to be identified.

Abstract: A method identifying a set of transponders situated in the interrogation field of analysis apparatus, with each transponder storing a different identity code. The analysis apparatus first transmits data, and each unidentified transponder compares this data with a portion of its own identity code, which portion is selected by the analysis apparatus, and then transmits in a time window, selected at least as a function of the result of the comparison. The analysis apparatus, then receives the data transmitted by the transponders, determines whether data enables any of the transponders identity codes. The analysis apparatus then emits modified data so that after a finite number of iterations the data causes each of the transponders to transmit data enabling the individual transponder's identity code to be determined.

Abstract: A method and apparatus for simultaneously storing a set of read/write or respond-to-order transponders located in a container. The method transmits radiation to read/write trnsponders to energize them, receives identity data transmitted by the transponders, verifies that the identity data are not subject to dispersion, transmits a data group to the transponders, and stores the data group in memories of the transponders. If the identity data are subject to dispersion, the method interrupts radiation transmission in order to deactivate the transponders and then retransmits the radiation until the data are not subject to dispersion so that the data group can be transmitted to the transponders for storage in their memories. In the case of respond-to-order transponders, a signal is also transmitted. If the identity data are subject to dispersion, the signal is retransmitted until the data are not subject to dispersion, and then the data group is transmitted to the transponders and stored in their memories.
