Abstract: An infusion system, which may be a closed loop, or “semi-closed-loop”, infusion system, uses state variable feedback to control the rate at which fluid is infused into a user's body. The closed loop system includes a sensor system, a controller, and a delivery system. The “semi-closed-loop” system further includes prompts that provide indications to the user prior to fluid delivery. The sensor system includes a sensor for monitoring a condition of the user and produces a sensor signal which is representative of the user's condition. The delivery system infuses a fluid into the user at a rate dictated by the commands from the controller. The system may use three state variables, e.g., subcutaneous insulin concentration, plasma insulin concentration, and insulin effect, and corresponding gains, to calculate an additional amount of fluid to be infused with a bolus and to be removed from the basal delivery of the fluid.

Abstract: A method of repositioning an injection port comprises positioning the injection port at a first location in a patient's body and extending fasteners of the injection port to substantially secure the injection port at the first location. The fasteners are then retracted to substantially unsecure the injection port from the first location in the patient's body. The injection port is then moved to a second location in the patient's body. The fasteners are then re-extended to substantially secure the injection port at the second location in the patient's body. The injection port includes a port body. The fasteners are integral with the port body. The fasteners may be selectively extended and retracted relative to the port body. For instance, the fasteners may be pivoted relative to the port body to transition between extended and retracted positions. The extension and retraction of fasteners may be provided through a port applier.

An optical domain image processing method includes the steps of providing at least two, complementary, angle sensitive pixel (ASP) structures; obtaining a spatial frequency domain ASP output including a plurality of complementary ASP response outputs, in response to an optical input; performing a wavelet-like transform of the ASP response outputs in the optical domain prior to performing any operation in a digital domain; and obtaining a desired output of the optical input.

Abstract: An injection port system comprises an injection port and an applier. The port comprises a body and a plurality of fasteners. The fasteners are integral with the body and are movable from a non-deployed position to a deployed position. The applier comprises a port engagement portion and an actuator. The port engagement portion is configured to selectively engage the port body to selectively retain the port relative to the applier. The actuator is operable to move the fasteners to the deployed position. The applier is also configured to disengage the port engagement portion from the port body to release the port from the applier when the actuator moves the fasteners to the deployed position. The actuator may release the port from the applier by moving a resilient member away from the port body as the actuator also moves the fasteners from the non-deployed position to the deployed position.

Abstract: A method for detecting occupancy status of a plurality of conference rooms in real time is provided. The method enables, firstly, monitoring a first output signal of a first sensor. Secondly, the method enables monitoring a second output signal of a second sensor. The method further enables comparing the first and second output signals with one or more predetermined thresholds within a predetermined time. Furthermore, the method enables correlating the comparison results to identify any uncertainty in detecting the occupancy. Furthermore, the method enables processing output from one or more image and/or video sensors based on the correlation to obtain occupancy status information when there is uncertainty in detecting occupancy. Finally, the method enables displaying the occupancy status information on one or more user devices.

Abstract: An image capturing apparatus includes a driving unit for displacing one of a lens unit and an imaging device with respect to an optical axis, and a controller for causing the driving unit to displace one of the lens unit and the imaging device, in response to the motion of the image capturing apparatus. When, with a shooting direction being moved, captured images are generated so that a panoramic image is generated from the captured images, the controller displaces the position of the lens unit or the imaging device at the start of exposure of each image to be captured in a direction based on a direction in which the shooting direction is moved. In addition, a displacement amount at the start of the exposure is set in response to the length of an exposure time period so that the displacement during the exposure time period becomes small and the quality of an image is improved.

Abstract: Devices and methods for balloon delivery of rapamycin and other hydrophobic compounds to the wall of blood vessels. Balloon catheters, such as those used for balloon angioplasty, are modified with the addition of a reservoir of dry micelles, disposed at a suitable location within the balloon or catheter. The reservoir may be installed within the angioplasty balloon, within a lumen in communication with the angioplasty balloon, either as a loose or packed powder or as a film coating. The micelle preparation is reconstituted and the micelles are mobilized when the aqueous solution used to inflate the balloons is injected into the catheter. The micelles are infused into tissue surrounding the balloon when pressurized fluid within the balloon leaks through the wall of the balloon.

Abstract: A relative quality score is provided that takes into account properties of an encoded version of a source video. For example, one such quality score calculates a difference of higher and lower quality transcoded versions of the source video, and computes quality metrics for each to evaluate how similar the transcoded versions are to the source video. A relative quality score quantifying the quality improvement of the high-quality version over the low-quality version is computed. The relative quality score is adjusted based on a measurement of the quality of the source video. If the relative quality score for the video indicates a sufficient quality improvement of the high-quality version over the low-quality version, various actions are taken, such as retaining the high-quality version, and making the high-quality version available to users, e.g. via a video viewing user interface.

Abstract: An injection port applier is configured to engage an injection port that has integral fasteners that are movable from a non-deployed position to a deployed position. The applier comprises a shaft, a port engagement portion, and a handle. The port engagement portion is includes a fastener deployment member that is operable to move the fasteners to the deployed position. The handle comprises a first handle portion and a second handle portion. The second handle portion is movable distally relative to the first handle portion in order to actuate the fastener deployment member, to thereby move the fasteners to the deployed position. An elongate actuating member couples the second handle portion with the fastener deployment member. One part of the elongate actuating member translates longitudinally in response to the second handle being moved distally; while another part of the elongate actuating member rotates in response to the first portion translating.
