20080204245 | METHOD, APPARATUS AND ARTICLE FOR DETECTION OF TRANSPONDER TAGGED OBJECTS, FOR EXAMPLE DURING SURGERY - A system determines the presence or absence of objects by interrogating or exciting transponders coupled to the objects using pulsed signals over a number of wide band frequency bands with dynamic tuning about a center frequency of each band and less sensitivity to noise fluctuation. | 08-28-2008 |
20080238677 | TRANSPONDER HOUSING AND DEVICE TO MARK IMPLEMENTS, SUCH AS SURGICAL IMPLEMENTS, AND METHOD OF USING SAME - A transponder device and/or housing to mark a surgical implement, such as a metallic surgical instrument, is provided that comprises a non-elastic, preferably non-metallic, rigid transponder housing attachable to a portion of the surgical implement. The housing includes a transponder receiving cavity spaced at least 1 millimeter, and preferably at least 2 millimeters, from any portion of the surgical implement when the housing is attached to the surgical implement. The housing may be removably attached to the surgical implement or permanently attached. In use, a transponder is installed in the transponder receiving cavity. A method of detecting a transponder indicating the possible presence of a surgical implement is also provided. | 10-02-2008 |
20080272913 | METHOD, APPARATUS AND ARTICLE FOR DETECTION OF TRANSPONDER TAGGED OBJECTS, FOR EXAMPLE DURING SURGERY - The presence or absence of objects is determined by interrogating or exciting transponders coupled to the objects using pulsed wide band frequency signals. Ambient or background noise is evaluated and a threshold adjusted based on the level of noise. Adjustment may be based on multiple noise measurements or samples. Noise detection may be limited, with emphasis placed on interrogation to increase the signal to noise ratio. Match filtering may be employed. Appropriate acts may be taken if detected noise is out of defined limits of operation, for example shutting down interrogation and/or providing an appropriate indication. | 11-06-2008 |
20090322485 | METHOD, APPARATUS AND ARTICLE FOR DETECTION OF TRANSPONDER TAGGED OBJECTS, FOR EXAMPLE DURING SURGERY - The presence or absence of objects is determined by interrogating or exciting transponders coupled to the objects using pulsed wide band frequency signals. Ambient or background noise is evaluated and a threshold adjusted based on the level of noise. Adjustment may be based on multiple noise measurements or samples. Noise detection may be limited, with emphasis placed on interrogation to increase the signal to noise ratio. Match filtering may be employed. Presence/absence determination may take into account frequency and/or Q value to limit false detections. Appropriate acts may be taken if detected noise is out of defined limits of operation, for example shutting down interrogation and/or providing an appropriate indication. | 12-31-2009 |
20100109848 | METHOD AND APPARATUS TO DETECT TRANSPONDER TAGGED OBJECTS, FOR EXAMPLE DURING MEDICAL PROCEDURES - The presence or absence of objects (e.g., medical implements, medical supplies) tagged with transponders may be determined in an environment in which medical procedures (e.g., surgery) are performed via an interrogation and detection system which includes a controller and a plurality of antennas positioned along a patient support structure. The antennas may, for example, be positioned along an operating table, bed, a mattress or pad or a sheet and may be radiolucent. Respective antennas may successively be activated to transmit interrogation signals. Multiple antennas may be monitored for responses from transponders to the interrogation signals. For example, all antennas other than the antenna that transmitted the most recent interrogation signal may be monitored. | 05-06-2010 |
20110004276 | METHOD AND APPARATUS TO DETECT TRANSPONDER TAGGED OBJECTS AND TO COMMUNICATE WITH MEDICAL TELEMETRY DEVICES, FOR EXAMPLE DURING MEDICAL PROCEDURES - The presence or absence of objects tagged with transponders may be determined in an environment in which medical procedures are performed via an interrogation and detection system which includes a controller and a plurality of antennas positioned along a patient support structure. The antennas may be positioned along an operating table, bed, mattress or pad, sheet, or may be positioned on a drape, or shade. Respective antennas may successively be activated to transmit interrogation signals. Multiple antennas may be monitored for responses from transponders to the interrogation signals. For example, all antennas other than the antenna that transmitted the most recent interrogation signal may be monitored. Antennas may be responsive to force, a signal indicative of such force being produced. A wireless physiological condition monitor may detect patient physiological conditions and wirelessly transmit signals indicative of such. | 01-06-2011 |

20100070426 | OBJECT MODELING FOR EXPLORING LARGE DATA SETS - An object model is used to facilitate performing financial analysis and that includes certain zero-order objects or building blocks that lend themselves particularly well to doing financial analysis. The object model comprises a universe of data items, relationships between the data items, higher-order objects generated based on one or more data items in the universe, higher-order objects generated based on other objects, and auxiliary entities related to the universe of data items. | 03-18-2010 |
20100070427 | DYNAMIC INDEXING - Techniques for dynamic indexing are provided. In one embodiment, first instruments to be included in an index are identified at a first time. The index includes one or more first weights each of which is associated with a different instrument in the first instruments. One or more first time series for the first instruments are determined. Based on the one or more first time series and the one or more first weights, a collective value of the index is tracked as a function of time at least from the first time. At least one of a) the first weights and the first time, and b) the collective value as the function of the time is stored, in a physical storage device. | 03-18-2010 |
20110179042 | Object Modeling For Exploring Large Data Sets - Techniques are described for facilitating performing computer-implemented financial analysis. A metric that transforms one or more time series into an output object is identified. The one or more time series are determined based on one or more input objects. The metric is applied using the one or more time series, thereby generating a particular value for the output object. One of the metric and the particular value for the output object is stored in a physical storage device. | 07-21-2011 |
