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.

An automated (robotic) floor cleaner (100) is adapted to allow sterile cleaning of sensitive environments, such as hospital room. In particular, the floor-cleaner chassis (124) is redesigned to be mounted on a deck (102) containing cleaning devices that contact the floor. The cleaning devices mounted on the deck (102) include vacuum head (132), brushes (120), cleaning fluid sprays (128), and conceivably sanitizing devices such as UV germicidal light, are provided pre-sterilized. As such, the adapted floor-cleaner chassis (124) allows the deck (102) to be mounted to the bottom of the chassis (124), the floor-cleaner (100) is then used to clean a floor, after which, the deck (102) is removed from the chassis (124) and disposed. The robotic-floor cleaner (100) and sterilization system cleans floor between or even during cases. Further, the robotic floor cleaner (100) reduces the “turnover time” required between cases, as it operates simultaneously while the staff prepares the room for the next case.

A patient table, modified with a fixed-base design thereby allowing for heavy patients, providing tilting and cantilevering capabilities, table top extension (i.e. providing head to toe coverage), and overall stability, is described. The operating room table re-design includes incorporation of utility sources into the architecture of the table, so that utilities, such as wiring, vacuum, and gas hoses, arise from the table itself. The source of all utilities to the table (as opposed to those emanating from the table) may come from an underground connection. Further, the table is interchangeable with tables customized for a specific procedure.

The present invention relates to a reagent refrigerator which comprises a reagent refrigerator compartment including reagent storing trays; an upper housing a cooling equipment compartment and a cooling purification compartment; a side duct defined by a side partition having a through hole at the side of the reagent refrigerator; one each of a second side duct, separately defined by a side partition having a through hole at the other side thereof, and a rear duct, separately defined by a rear partition having a through hole at the rear side thereof; and an upper duct having one end communication with the upper portion of the second side or rear side, and the other end communicating with the cooling purification compartment. Accordingly, refrigeration temperature of the reagent refrigerator can be controlled, and circulation flow in the reagent refrigerator is improved, to thereby purify the air therein and minimize deviations from refrigerator temperature values. In addition, since the reagent refrigerator is based on a closed circulation type structure, impurities are prevented from being introduced to the reagent refrigerator to thereby increase the service life of the filter and reduce energy consumption. Moreover, even when the door of the reagent refrigerator is opened, negative pressure distribution in the reagent refrigerator is relatively even, thereby preventing the emission of noxious gas and an offensive smell from the reagent refrigerator compartment to the indoor space. More particularly, the reagent refrigerator may be modified to have a partial opening circulation structure without a heater to thereby prevent explosions and to perform a defrosting/dehumidifying operation so that safety and economic feasibility can be improved. In addition, the reagent refrigerator can be automatically controlled and the internal condition of the reagent refrigerator compartment can be monitored in real time. Furthermore, not only can on-site/real-time control be executed, but remote control as well.
