  • Publication number: 20190239886
    Abstract: A surgical stapler includes an anvil half and a cartridge half. The anvil half includes an anvil channel member and an anvil surface. The cartridge half releasably couples with the anvil half and includes a cartridge channel member having a distal portion that receives a staple cartridge, and a latching member coupled to the cartridge channel member and movable between open and closed positions. A resilient member is arranged at a proximal end of one of the anvil half or the cartridge half, and a projection is arranged at a proximal end of the other of the anvil half or the cartridge half. The resilient member is configured to contact and releasably couple with the projection to thereby couple the proximal end of the anvil half with the proximal end of the cartridge half while the latching member is in the open position.

  • Patent number: 9836630
    Abstract: An RFID tag reading system and method accurately and rapidly determine true bearings of RFID tags associated with items in a controlled area. An RFID reader has an array of antenna elements and a plurality of RF transceivers. A controller controls the transceivers by steering a primary transmit beam over the controlled area to each tag, by steering a primary receive beam at a primary steering angle from each tag, by steering a plurality of secondary receive beams at different secondary steering angles that are offset from the primary steering angle by receiving secondary receive signals from each tag, and by processing the secondary receive signals to determine a true bearing for each tag. Bidirectional communication between the reader and a tag is conducted over a single inventory round in which the tag is read a plurality of times by the primary and the secondary receive beams.

  • Patent number: 9773136
    Abstract: A radio frequency identification (RFID) tag reading system and method accurately and rapidly determine, in real-time, true bearings of RFID tags associated with items in a controlled area. Primary transmit and receive beams are steered over the area, and multiple secondary receive beams are substantially simultaneously steered to a plurality of bearings in the area. The highest signal strength of secondary receive signals from the secondary receive beams determines an approximate tag bearing of each tag. Two secondary receive beams at opposite sides of the approximate tag bearing in elevation are selected to obtain a pair of elevation offset signals, and two secondary receive beams at opposite sides of the approximate tag bearing in azimuth are selected to obtain a pair of azimuth offset signals. The elevation offset signals and the azimuth offset signals are processed to determine a true bearing for each tag in real-time.

  • Publication number: 20170177912
    Abstract: A radio frequency identification (RFID) tag reading system and method read RFID tags in a controlled area in real time with an enhanced performance. An RFID reader reads a mixed tag population of interesting RFID tags and of uninteresting RFID tags in the controlled area at a read rate. A controller dynamically and continuously monitors the read rate in real time, dynamically selects the interesting RFID tags, or deselects the uninteresting RFID tags, in real time when the read rate is below a reading threshold, and dynamically controls the RFID reader in real time to only read the interesting RFID tags when the read rate is below the reading threshold.

  • Patent number: 9111190
    Abstract: A radio frequency identification (RFID) tag reading system having a phased antenna array accurately locates RFID tags in a controlled area, by steering an interrogating beam over the controlled area to interrogate the tags and generate return modulated RF signals. A primary receiver steers a primary receive beam at a primary steering angle that is fixed during each tag interrogation. A primary demodulator demodulates and reconstructs the received return modulated signals. A secondary receiver, independently of the primary receiver, steers a secondary receive beam at a plurality of secondary steering angles. A secondary correlator/demodulator demodulates the combined return modulated signals, and utilizes the reconstructed signal reconstructed by the primary demodulator at each of the secondary steering angles. Both the primary and the secondary receivers cooperate to accurately locate the same tag.
