Methods and systems for controlling the usage of devices with embedded RFID tags including connecting a device to an energy source and reading data from a memory device incorporated in the device. The data may include a unique identifier (UID), a usage value, an activation value, a reprocessing value, and/or a sterilization indicator. The usage value is incremented when the device is connected to the energy source and the activation value is incremented when the device is activated permitting energy to flow from the energy source to the device. Usage of the device is prevented if the UID is on a list of prohibited UIDs, the usage value is not lower than a usage limitation value, the reprocessing value equals a reprocessing limitation value, the activation value equals an activation limitation value, and/or the sterilization indicator does not indicate that the device has been sterilized since its previous usage.

System and method for using RFID tags to determine sterilization of devices

Authentication systems and methods for a population of devices each associated with an RFID tag are described. For each device, a secret key is combined cryptographically with a publicly-readable unique identifier (UID) of an RFID tag to obtain a unique authorization signature. The RFID tag is prepared utilizing the unique authorization signature as memory-access and/or tag-operation password(s). The systems and methods may safeguard against attacks whereby compromise of a single tag will not compromise the entire population of devices and may reduce or eliminate the use of inappropriate surgical devices during a surgical procedure.

RFID secure authentication

A radio frequency identification (RFID) network is presented including a plurality of medical devices each including an RFID transponder and a single RFID transponder emulator configured to emulate functionality of each of the RFID transponders of the plurality of medical devices. The RFID network further includes a plurality of RFID interrogation devices configured to operatively communicate with the single RFID transponder emulator. The single RFID transponder emulator is used for development, testing, evaluation, and validation of each of the plurality of RFID interrogation devices.

The present personal watercraft is comprised of a hull with a center portion, and a pair of elongated side pontoons extending substantially behind the center portion. A rear-facing seat is arranged on the rear of the center portion. The rear of the hull behind the seat and between the pontoons is open for enabling a rider to kick for propulsion. The center portion and the pontoons each have a curved bottom for improving directional control. The hull includes a bow with a substantially slanted bottom, and sides that converge to a point for improving speed and gliding over seaweed. The hull is preferably made of a floatable rigid material. A watertight storage compartment is provided in the center portion for stowing equipment. Seat belts are connected across the seat for securing a rider in rough water. A removable apron is stretched across the pontoons behind the seat for use in fly fishing. A detachable harness attached to the top of the pontoons allow the watercraft to be carried on the back of a person. A detachable undercarriage and tow bar allow the watercraft to be towed behind a vehicle. A camouflage mesh tent is removably attached on the hull for use in hunting.
