  • Publication number: 20220262098
    Abstract: A method includes classifying, via a computational model, images of a source image stream as valid images or invalid images based on whether the images include biological tissue or a surgical tool; and generating a condensed image stream that includes the valid images. Another method includes classifying input images as valid images or invalid images using: a clustering algorithm that classifies each of the input images into either a first group or a second group and using labels that indicate whether the input images include a surgical tool. The method also includes training a computational model to identify the valid images based on whether the valid images include biological tissue or a surgical tool, or whether the valid images have at least a threshold level of clarity.

  • Publication number: 20090130269
    Abstract: A sugar coating is formed on a solution multiplicity of items (5) such as confectionery, using a suspension of crystal nuclei in a solution of sugar. This suspension is created by ultrasonic irradiation of a supersaturated solution. For example a saturated solution is cooled, and stored in a tank (16) connected to a recirculation (10) loop (18) containing a pump (24) and an ultrasonic irradiation module (26). Treated suspension (20) is withdrawn to coat items (11), and new supersaturated solution (14) is introduced. The sugar solution is sufficiently viscous to suppress crystal growth.

  • Publication number: 20040174528
    Abstract: Schemes for computing performance parameters of fiber-optic gyroscopes (FOGs) using closed-loop transfer functions are described herein. In one embodiment, a method to compute a performance parameter of a FOG may include providing a closedloop transfer function based on optical components and electrical components of the FOG; based on the transfer function, determining a relationship between the performance parameter and at least one physical parameter associated with at least one component of the FOG; and, based on the relationship, computing the performance parameter.

  • Patent number: 6640189
    Abstract: A method of reacquiring a satellite signal within an integrated GP/IG navigation system includes detecting a loss of synchronization between a timing code in the satellite signal and a corresponding reference timing code. The method includes receiving position data from an inertial guidance unit. The position data is representative of an estimated position (and its associated uncertainty) of the navigation system. The method also includes estimating a distance from the navigation system to the satellite, as a function of the position data, and deriving an initial delay from the distance. The method includes delaying the reference timing code, with respect to the timing code embedded in the satellite signal, by an offset delay substantially equal to the initial delay. The method includes incrementally varying the offset delay until the timing code embedded in the satellite signal is synchronized with the reference timing code, or until the offset delay equals a predetermined end limit value.

  • Patent number: 6622091
    Abstract: A method of calibrating acceleration data signals from a set of accelerometers, and angular rate data signals from a set of gyroscopes within a combined GPS/IGS includes generating navigation data as a function of the acceleration data signals, the angular rate data signals, and prior navigation data. The method further includes combining the navigation data with GPS data via a Kalman filter, so as to produce corrected navigation data, navigation correction data, acceleration correction data and angular rate correction data. The method further includes modifying the acceleration data signals as a function of the acceleration correction data so as to calibrate the acceleration data signals, and modifying the angular rate data signals as a function of the angular rate correction data, so as to calibrate the angular data signals.

  • Publication number: 20020158796
    Abstract: A method and system for integrating a IGS system and a GPS receiver. A predictive filter can measure signal quality from the GPS receiver and accordingly provide parameter estimates by appropriately weighting signal data from the GPS receiver and the IGS system. When GPS signal quality is high, the GPS signal data can be provided proportionately greater weight than the IGS system data, and the IGS/GPS integrated filter outputs can provide compensation to the IGS system for bias errors, etc. Alternately, if the GPS signal data is degraded or unavailable, the IGS signal data can be provided proportionately greater weight than the GPS signal data to provide higher quality inputs to the GPS receiver trackers than would otherwise be available.
