Abstract: A gastric bypass device includes an occlusion device that is adapted to be deployed relative to a patient's pyloric sphincter, an anastomosis anchor that is adapted to be deployed relative to an anastomosis between the patient's stomach and their small intestine, and a tether that extends through the patient's small intestine between the occlusion device and the anastomosis anchor. A dynamic leash may be secured relative to the occlusion device and may work in conjunction with the tether to help hold the occlusion device in place. The gastric bypass device may be deployed using a variety of methods including a push-pull wire method, a rail method, a garage method, a two-piece method and a comprehensive method.

Abstract: A method for measuring glucose concentration in a biological material is disclosed, as well as a computer readable medium and a sensor system for performing the method. The method comprises irradiating the biological material with optical radiation having a first wavelength between 400 nanometers and 25 micrometers; detecting a first signal from the biological material at the first wavelength; irradiating the biological material with radio-frequency, RF, radiation having a second wavelength between 1 millimeter and 30 centimeters; detecting a second signal from the biological material at the second wavelength; and determining a concentration of glucose in the biological material based on the first signal and the second signal. The sensor system comprises an optical radiation source, an optical radiation detector, an RF radiation source, and RF radiation detector, and a processing device.

Abstract: A system includes a navigation antenna configured to receive first satellite signals transmitted from a first type of satellite in a first frequency band and second satellite signals transmitted from a second type of satellite in a second frequency band and generate RHCP signal responses based on the first and second satellite signals, a plurality of science antennas configured to receive the first satellite signals in the first frequency band and the second satellite signals in the second frequency band as reflected from a ground surface and generate LHCP signal responses and RHCP signal responses based on the first and second satellite signals, and a receiver module including a processing module and a plurality of receivers coupled between the navigation antenna and the plurality of science antennas and the processing module. The processing module is configured to generate telemetry data based on the received LHCP and RHCP signal responses.

Abstract: A surgical system for penetrating and determining a characteristic of tissue. An instrument generates rotational torque, and a drill bit tool body extends along an axis between a distal end to engage tissue and a proximal end to couple to the instrument. An emitter operatively coupled to the instrument emits light. A detector operatively coupled to the instrument detects light. An emission lightguide within the tool body transmits light emitted by the emitter toward the tissue as the instrument rotates the tool body. A detection lightguide within the tool body is spaced from the emission lightguide and transmit light reflected by the tissue toward the detector as the instrument rotates the tool body. The emitter emits light into the emission lightguide along the axis, and the detector detects light reflected from the tissue exiting the detection lightguide transverse to the axis when the tool body is coupled to the instrument.

Abstract: This disclosure relates to systems and methods for measuring wave fields of a body of water. A system can include a radiation source and an antenna that can cooperate with the radiation source to transmit a radio frequency (RF) signal to a wave field having one or more waves. The antenna can receive backscattered signals from the wave field. The system can include a local oscillator and a processor. The local oscillator downconverts the backscattered signals into baseband signals and the processor can process the baseband signals to determine a relative velocity of each of the waves of the wave field. The processor can further be programmed to identify an observed portion of the backscattered signals as bad data and remove the bad data from further processing.

Abstract: Methods and systems for imaging the fundus of the eye are disclosed, in which the fundus is illuminated through a mask which blocks light from reaching one or more masked regions within a peripheral area surrounding a target area of interest, such as the macular region. An image is obtained of both the target area and the peripheral area. A scattered light value is derived from the image intensity within the masked regions, and this is used to compensate and adjust the measured intensity of light within the target area. When employed in the measurement of macular pigment optical degeneration, an improved measurement is obtained in which the specific image(s) used for measurement have a specifically calculated correction factor applied to compensate for light scatter, rather than relying on population-based average scattering values.

Abstract: A golf putting training device for a golfer comprising an elongate rigid support member, a pair of arm-embracing members for receiving therethrough and partially encircling the golfer's forearms, each arm-embracing member mounted on the support member for longitudinal movement relative to the other arm-embracing member and for independent pivotal movement relative to the bar about a pivot axis extending substantially perpendicularly of the longitudinal extent of the bar. The arm-embracing members each comprise a tapered, tubularly formed sleeve having a larger diameter at one end of the sleeve for fitting snugly over the golfer's upper forearm adjacent the crook of the elbow and a smaller diameter at the opposite end of the sleeve for fitting snugly over the golfer's lower forearm adjacent the wrist.
