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 apparatus and method for interrogating and automatically identifying a radio-frequency tagged surgical instrument tray and its contents of RFID-tagged surgical instruments are disclosed. The surgical instrument tray and its contents come into contact with an RF signal transmitted by the RFID reader, and as a result, the RFID tags affixed on the instrument tray and the surgical instruments respond by transmitting back to the RFID reader data pertaining to the history of the surgical instruments. A data terminal, which is connected to the RFID reader, may contain data pertaining to the radio frequency tagged surgical instruments during packaging, and during the return of the surgical instrument trays to the packager, identifies the surgical instruments.

A method and apparatus for automatically identifying the contents of an instrument tray by use of a radio-frequency tag (RFID) is disclosed. The method, apparatus, and system enable the instrument tray to receive an interrogation signal from a reader and to respond to the interrogation signal with a code comprised of its identifying information as well as its contents of radio frequency tagged instruments. Both the instrument tray and/or the reader may be coupled by a proximity electromagnetic field, an inductive coupling, or may be units of a wireless LAN system such as a wireless fidelity local area network. The interrogation signal interrogates the tray to ascertain its contents, and the tray in turn transmits a signal to the reader to inform the reader of its contents. The method, apparatus, and system can track, inspect, and verify inbound and outbound surgical instrument trays and kits, to assess, for example, the surgical instruments' and trays' duty life cycle usage.

A control system for an RFID-based system for assembling and verifying outbound surgical equipment corresponding to a particular surgery. A user enters a identification number of a surgery. The control system queries a database of surgery information and outputs a list of required surgical equipment, such as surgical instrument sets. An operator uses the list to pick instrument sets for loading into a shipping tote. Each set is tagged with an RFID inventory tag that stores identification information for that set such as a set name and ID number. The shipping tote is passed through an RFID reader and identification data read from the tags is compared against the identification data for sets required for that surgery. A status indicator is activated to alert a user as to whether the surgery is complete that is, all expected sets are present, or that exception handling is required. The control system updates a database such as an ERP system to reflect that the surgery including the required sets has shipped—and the sets are inventoried out to the intended recipient.

In a method and apparatus for generating a magnetic resonance image, raw magnetic resonance data are acquired from a subject for each of a number of PROPELLER strips using, for each strip, multiple magnetic resonance reception coils in a partial acquisition technique (PAT), and the raw data in said PROPELLER strips are entered into k-space according to the PROPELLER scan. A PAT reconstruction of the data in k-space is conducted dependent on the respective sensitivities of the reception coils, and a PROPELLER reconstruction of the data in k-space is conducted after the PAT reconstruction for generating a magnetic resonance image of the subject.

Conductive material may be deposited in the trenches to form electrodes, and the insulating layer may be conditioned so that the electrodes protrude above the insulating layer. A 2D material, such as graphene, may be deposited on the electrodes to form a channel between the electrodes.

Detectors determine the presence of valid sinusoids for DTMF, MF-R1 and MF-R2 protocols for encoding dialed digits. The detectors split electrical signals into subbands. Energies within the subbands are analyzed to determine a presence of sinusoids corresponding to frequencies of dialed digits. In one embodiment, the detectors comprise a PS-IIR filter to split the electrical signal into the subbands. The detectors further comprise at least one bank of filters, such as notch filters, corresponding to the number of possible relevant frequencies within the respective subbands. The detectors further comprise detection logic comprising tests, which may include analyzing the output(s) from the bank of filters. Optionally, a preclassifier is employed to predetermine which filters in the banks of filters are to be executed. The detectors, typically deployed in digital signal processors, allow for an increase in the density of detectors and provide robust performance in talk-off situations.

A liquid crystal based polarimetric system, a process for the calibration of this polarimetric system, and a polarimetric measurement process intended for measuring the representative parameters of a sample in which the polarimetric system contains an excitation section emitting a light beam that passes through a polarization state generator (PSG) and onto a sample. After reflection or transmission by the sample, the beam goes through an analysis section with a polarization state detector (PSD). The PSG and PSD each have a first and a second liquid crystal elements LC_j (j=1,2) having, for each LC_j element of the PSG (respectively for each LC_j element of the PSD), an extraordinary axis making an angle θ_j (resp. θ′_j) with respect to the polarization direction (i), and a retardation δ_j (resp (δ′_j) between its ordinary and extraordinary axes, the liquid crystals LC_j elements being positioned in reverse order in the PSD with respect to the LC_j elements of the PSG.

Apparatuses and method for real-time measuring ultrashort pulse shape and pulse width. Transient-grating effect on a transparent optical medium is used to generate a reference beam. A black plate with four equal-sized holes divides the incoming laser beam into four beams, one of which is attenuated and introduced an appropriate time delay relative to the other three. The four laser beams pass through a concave mirror and are focused onto a nonlinear transparent optical medium. The three beams without attenuation are used to generate a transient-grating light in the transparent medium. The transient-grating light is collinear and overlapped with the fourth attenuated beam. According to the third-order nonlinear effect, the transient-grating light has a broader spectral bandwidth and more smooth spectrum phase with respect to the incident laser. By measuring the spectral interference, the spectrum and spectral phase may be retrieved by spectral interferometry.
