Abstract: A technique for tracking, for example, the temperature of one or more sample vials containing biological material stored in a low-temperature shipping vessel. Each sample vial has vial electronics that senses temperature and transmits temperature data to the reader head of a reader device, which has a controller that is not at the low temperature. In some implementations, the shipping vessel has a cap with a recess that houses the controller and a hollow plug that houses a cable that connects the controller to the reader head that is located in the vessel's cold interior sufficiently close to the sample vial to enable interaction with the vial electronics. In some implementations, the reader head transmits electrical power to the vial electronics. By tracking the temperature of individual sample vials rather than the temperature of the vessel interior, more-relevant temperature data is available.

Abstract: RFID tags are affixed to vials used to store samples, such as biological samples stored in liquid nitrogen dewars or mechanical freezers. In one set of embodiments, an RFID tag is inserted into a recess at the bottom of a vial and held in place by an insert that engages with vial structure. In another set of embodiments, the RFID tag is retained in the recess by directly engaging with the vial structure and without using a separate insert. Mechanisms for keeping the insert and/or tag in place include tabs that gouge into the vial material, clips that allow the insert/tag to be inserted, but not removed, and holes in the side wall of the vial recess that receive tabs extending from the insert/tag. Tag-insertion techniques enable tags to be affixed to vials either before or after insertion of the sample, thereby enabling retrofitting of existing sample-storing vials with tags.

Abstract: In one embodiment, a cold storage system for biological samples has one or more freezers, each freezer having one or racks, each rack receiving one or more boxes, each box receiving one or more sample containers. In addition to the biological sample, each sample container has a unique passive RFID tag. Control electronics in each box energize reader coils to query individual RFID tags. Control electronics in each rack communicate with and provide power to the control electronics of each corresponding box, and control electronics in each freezer communicate with and provide power to the control electronics of each corresponding rack, and a host computer communicates with the control electronics in each freezer. In each instance, communication and power provisioning is implemented using magnetic inductive coupling. The system is able to determine the identity of each sample container in the system and maintain that information in a database.

Abstract: In one embodiment, an antenna configuration for locating RFID tags has two sets of (mutually orthogonal) elongated reader coils, where each elongated reader coil corresponds to two or more different possible locations of RFID tags, and each possible location is associated with one reader coil in each of the two sets. The identities and locations of RFID tags can be determined by (sequentially) energizing the different sets of reader coils and correlating the recorded responses from RFID tags. In one application, the antenna configuration is used at the box level of a cold storage system for biological samples having one or more freezers, each freezer having one or racks, each rack receiving one or more boxes, each box receiving one or more sample containers, where, in addition to the biological sample, each sample container has a unique passive RFID tag.
