Abstract: Illumination devices for impinging light on tissue, for example within a body cavity of a patient, to induce various biological effects are disclosed. Biological effects may include at least one of inactivating and/or inhibiting growth of one or more pathogens, upregulating a local immune response, increasing endogenous stores of nitric oxide, releasing nitric oxide from endogenous stores, and inducing an anti-inflammatory effect. Biological effects may include upregulating and downregulating inflammatory immune response molecules within a target tissue. Wavelengths of light are selected based on intended biological effects for one or more of targeted tissue types and targeted pathogens. Light treatments may provide multiple pathogenic biological effects, either with light of a single wavelength or with light having multiple wavelengths.

Abstract: A device, system, and/or method may be used to provide an adaptive alignment. A first video data may be received. The first video data may comprise a first video frame and a second video frame. Sensor pose data may be determined. The pose data may be associated with the first video frame and the second video frame. An adjusted video frame may be determined based on the first video frame and a motion indicated by the pose data. A frame adjustment value may be determined by comparing a first pixel from the adjusted video frame to a second pixel from the second video frame. The frame adjustment value may correlate the pose data to the first video data. A second video data may be determined by applying the frame adjustment value.

Abstract: A method forming packaged semiconductor devices includes providing a completed semiconductor package having a die with bond pads coupled to package pins. Sensor precursors including an ink and a liquid carrier are additively printed directly on the die or package to provide precursors for electrodes and a sensing material between the sensor electrodes. Sintering or curing removes the liquid carrier such that an ink residue remains to provide the sensor electrodes and sensing material. The sensor electrodes electrically coupled to the pins or bond pads or the die includes a wireless coupling structure coupled to the bond pads and the method includes additively printing an ink then sintering or curing to form a complementary wireless coupling structure on the completed semiconductor package coupled to the sensor electrodes so that sensing signals sensed by the sensor are wirelessly transmitted to the bond pads after being received by the wireless coupling structure.

Abstract: A system and method for material handling includes a first portable conveyor for feeding material to a mobile bridge conveyor for the material to be stacked via a stacker until a discharge end of the mobile bridge conveyor is at or within a predetermined distance of a discharge end of the first portable conveyor. The first portable conveyor moves away from the mobile bridge conveyor after the discharge end of mobile bridge conveyor is at or within the predetermined distance of the discharge end of the first portable conveyor. A second portable conveyor that feeds material to the first portable conveyor rotates such that a discharge end of the second portable conveyor is moved towards the mobile bridge conveyor until reaching a feeding position for feeding material to the mobile bridge.

Abstract: A fast and accurate non-contacting angle sensor. According to one aspect of the described sensor and method of operation thereof, the angular orientation of an inner payload relative to an outer structure is monitored with a 2 axis optical angle sensor for azimuth and elevation angles. The sensor operates on the same principle as an autocollimator, thus it measures both azimuth and elevation angles simultaneously. The angle sensor measurements are highly accurate in the angles of interest, while having low sensitivity to translation in three axes and low sensitivity to roll angle between the inner payload and the outer structure.

Abstract: An optical filter for generating a filter output signal from a filter input signal, the filter output signal consisting of light from the filter input signal in a predetermined bandwidth. The filter includes a grating, a first optical assembly and an optical signal path. A portion of the input signal traverses the optical signal path such that it is diffracted from the grating to form a first intermediate beam that is input to the first optical assembly, which generates a second intermediate beam therefrom. The second intermediate beam is directed back to the grating and is diffracted by the grating, a portion of the diffracted second intermediate beam forming a portion of the filter output signal. The second intermediate beam is the inverted image of the first intermediate beam, and hence, the second reflection from the grating compensates for the time dispersion introduced by the first reflection from the grating.

Abstract: A transmission system models changing characteristics of a transmission medium in which it operates and schedules transmission accordingly. For any two transmissions that are desired to be made on the same resource, the system determines whether the transmissions may be made simultaneously without causing interference given a current state of the transmission medium. If the transmissions may be made without causing interference, they are. If not, one transmission is sent in favor over another as determined by a predetermined scheduling criterion. The system modulates a rate at which new data is admitted to the system. The system calculates an arrival rate that is likely to be (but is not necessarily) stable and modulates the actual arrival rate accordingly.

Abstract: An improved peritoneal dialysis method and system is provided. The method utilizes a tidal oscillating pulse peritoneal dialysis system. To this end, a system for providing peritoneal dialysis to a patient is provided.

Abstract: An improved on-line, real time hemodialysis monitoring system for hemodialysis treatment, quantitates the rate and amount of a constituent, such as urea, removed during the hemodialysis treating by measuring the constituent concentrations as a function of time in the spent dialysate effluent from a hemodialysis machine. A quantity of the spent dialysate effluent is removed from the dialysate effluent waste line periodically for testing. A urea concentration time profile can be analyzed to determine the urea removal, KT/V, URR, SRI, and normalized protein catabolic rate (nPCR) indices. The hemodialysis monitoring system preferably can obtain a dialysate sample equilibrated with the blood prior to the start of a hemodialysis treatment.

Abstract: There is disclosed a method and apparatus for automatically conducting peritoneal equilibration testing. The method involves removing a sample of overnight dwell fluid from a patient in an amount sufficient to determine the concentration of a metabolite in the drain fluid. The concentration of the metabolite in the sample is then detected and the overnight dwell fluid is drained and weighed. A known weight of dialysate fluid is instilled into a patient and thereafter there are periodically withdrawn samples of the dialysate fluid and the concentration of metabolite in each sample is determined. The ratio of metabolite concentration of each of the periodically drawn samples to metabolite concentration for the overnight dwell fluid is determined. The patient is then drained after a predetermined dwell time and the volume of drained dialysate is determined. The mass transfer area coefficient of the patient's peritoneal membrane is then obtained as a function of the measured variables.
