Abstract: Parameters extracted from high definition manometric measurements of the pharynx and upper esophagus at preidentified locations and times are applied to a supervised learning machine trained using x-ray fluoroscopy data to provide diagnostic information comparable to that of x-ray fluoroscopy without radiation exposure.

Abstract: Systems, processes, and computer program products may be used to perform retinal surgery. In particular implementations, a system, a process, and a computer program product may include the ability to inject a retina manipulation fluid into an eye through an injection/extraction system and apply negative pressure to the injection/extraction system to facilitate extraction of fluid from the eye. The system, the process, and the computer program product may also include the ability to adjust the applied negative pressure.

Abstract: An accessory is adapted to removably couple to a laser source connector separate from a fiber connector. The accessory includes a first contact element configured to form an electrical connection to a first portion of the laser source connector. The accessory further includes a second contact element configured to form an electrical connection to a second portion of the laser source connector. The second portion of the laser source connector is electrically insulated from the first portion of the laser source connector. The accessory also includes a network connected to the first contact element and the second contact element. The network establishes a defined electrical characteristic between the first and second contact element when a fiber connector is connected to laser source connector.

Abstract: An infusion cannula adapted to generate a spiral, laminar flow therein. In some implementations, the infusion cannula may include one or more flow-altering devices disposed within a passageway of the cannula.

Abstract: An endoillumination system comprises a system controller and a light modulation apparatus responsive to the controller to alter at least one parameter associated with a input light beam to generate a modulated light beam. The endoillumination system further comprises an optical fiber for carrying the modulated light beam and a probe through which at least a portion of the optical fiber extends. The probe is sized for insertion into an eye.

Abstract: A sized spoke weight has a partially cylindrical body with a longitudinal slot, and a first end and an opposite second end. The first end locates towards the hub of a wheel when installed and the second end locates towards the nipple of a spoke, that is, towards the rim of a wheel. The slot extends from the first end to the second end and allows the sized spoke weight to fit over an existing spoke and nipple. Proximate the second end, the slot has a greater diameter to accommodate an existing nipple during installation. The length and diameters of the sized spoke may be adjusted to provide various weights for users. The sized spoke weight is generally made of brass and has various sizes with corresponding weights for wheel balancing. The present invention minimizes environmental contamination.

Abstract: A method for extracting proteins from the intercellular space of plants is provided. The method is applicable to the large scale isolation of many active proteins of interest synthesized by plant cells. The method may be used commercially to recover recombinantly produced proteins from plant hosts thereby making the large scale use of plants as sources for recombinant protein production feasible.

Abstract: A capacitive level detection system provides a highly accurate determination of liquid level within a container. The primary sensor is an elongate capacitive probe positioned vertically within the container so that a lower portion of the probe is in liquid and an upper portion of the probe extends above the surface of the liquid. A capacitive liquid reference sensor is proximate the lower end of the probe, and a capacitive gas reference sensor is proximate the upper end of the probe. A controller is provided for driving each of the sensors with an electrical signal and reading a resultant value corresponding to the capacitance of each of the sensors. The controller is configured to enable the system to be calibrated prior to installation by placing each of the sensors in a calibration or identical medium, reading sensor values corresponding to capacitances for each of the sensors, and calculating and storing calibration values based on the sensor values.
