The present invention provides a technique for an access point (AP) to maintain a basic service set (BSS) on two or more channels simultaneously by temporarily blocking one BSS and servicing the other BSS while the other BSS is blocked, thereby providing an efficient way to create a dual cell AP with only a single radio. In an embodiment of the invention, a method for servicing a first set of wireless stations operating on a first channel of an access point and a second set of wireless stations operating on a second channel of the access point comprises transmitting, at a first time, a first frame from the access point to the first set of wireless stations via the first channel, the first frame having duration data directing the first set of wireless stations to cease transmitting until a second time represented by the duration data and servicing the second set of wireless stations via the second channel of the access point for at least a part of a time period between the first time and the second time. The method further comprises transmitting, at the second time, a second frame from the access point to the second set of wireless stations via the second channel, the second frame having duration data directing the second set of wireless stations to cease transmitting until a third time represented by the duration data of the second frame and servicing the first set of wireless stations via the first channel of the access point for at least a part of a time period between the second time and the third time. The method also may comprise transmitting a Delivery Transmission Indication Map (DTIM) frame prior to transmitting each of the first and second frames. The transmission of the DTIM frame preferably occurs substantially simultaneously with a Target Beacon Transmission Time (TBTT) of the access point.

A surgical instrument tray shipping tote identification system is provided. During transit to or from a medical facility, processing center, distribution center or other location, multiple surgical instruments trays are placed in an instrument tray shipping tote. Each instrument tray includes at least one RFID transponder tag storing identification information about that tray. The shipping tote has a bar coded shipping label affixed to one surface generated at the point of origin. When the tote arrives at the distribution center, it is placed on a conveyor system that includes a reading station having an RFID transceiver and a bar code reader. Information read from the RFID transponder tags and the bar code label is transmitted by a controller to an external database to check for any off-nominal status indicators. Once this check is performed, an indication is sent back to the controller and an appropriate indicator on the identification system is activated.

A radio frequency identification (RFID) workstation reader for RFID-enabled surgical instruments and surgical instrument trays and a method of using a RFID workstation reader to read RFID-enabled surgical instruments and surgical instrument trays is disclosed. The method, apparatus, and system enable individual instruments or a surgical instrument tray containing several surgical instruments to be quickly and efficiently inventoried and tracked. An instrument or instrument tray is placed on the workstation reader. An RF field generated by a plurality of antennae, causes RFID tags embedded in or attached to the instrument or instrument tray to emit a signal containing item specific identification information stored in the tags. The information is received by a control circuit and passed to a computer for data analysis. A status LED is illuminated on the workstation reader based on the results of the data analysis. The method, apparatus, and system can track, inspect, and verify inbound and outbound surgical instrument kits, and help to assess the surgical instruments' and trays' duty life cycle usage.

An RFID tag that incorporates at least one integral or permanently attached twist-tie fastener for easy attachment, detachment and reattachment to various items to be inventoried is provided. The RFID tag is included at least partially in a protective housing to permit it to be utilized in hostile environments. The twist-tie portion is attached to the tag and preferably is constructed of a braided or single strand wire. One or more visual indicia also may be printed on the face of the protective housing.

Persistent protection for application-specific or dependent software such as a workbook for use with independent software (such as Excel™) includes encryption of at least some instructions or other key information before distribution hence providing intellectual property security and (optionally) location security. The cooperative decoder module provides means for secure and controlled decryption of the secured content, if the cooperative security module has confirmed an authorised environment. The invention provides persistent security such that the secured content remains encrypted and is barred from access such as by a hacker, so cannot feasibly be amended or published.
