Abstract: A negative pressure device having a negative pressure source, a canister in fluid communication with the negative pressure source, a conduit the can couple with a wound dressing to provide negative pressure to a space beneath the wound dressing. Some arrangements of the negative pressure source can have a first noise reduction chamber and a second noise reduction chamber downstream of and in fluid communication with an outlet of a pump. The first and second noise reduction chambers can be configured to reduce noise generated by the pump and/or a level of pressure pulses in the fluid that is advanced through the negative pressure source.

Abstract: In various implementations, a multi-axis GUI may be generated for rendition on a display. The GUI may be operable to navigate its focus through an array of selectable tiles along multiple axes. Each of the selectable tiles may be selectable to access a respective document from an online corpus. Based on directional input, the focus of the GUI may be shifted in a direction of the directional input from a first selectable tile to a second selectable tile of the array. Multiple distinct search queries may be formulated based on documents corresponding to the second tile and/or other tiles of the GUI. Sets of document(s) that are responsive to the multiple queries may be obtained and used to generate selectable tiles along axes of the GUI.

Abstract: A leisure equipment trolley includes an elongate base spine aligned with the longitudinal axis of the trolley, at least two rear wheels and one front wheel being mounted on the base spine, and load support means on which a load can be mounted in use. The trolley further includes a collapsible support frame being mounted on the spine and movable from a collapsed condition wherein the support frame is adjacent the spine to an operational condition in which the support frame is upstanding from the spine. The support frame includes two elongate frame members, first ends of which are pivotally connected together, the other end of the first elongate frame member being pivotally mounted to the base spine, the other end of the second elongate frame member being movably mounted on the base spine so as to be moveable along the spine.

Abstract: An image monitoring system uses wireless communications to transmit images for security monitoring. The system includes a central controller (105) and a plurality of digital still camera units (110) operatively connected to the central controller (105). At least one of the camera units (110) includes an image sensor (215), a motion detector (220) that causes the image sensor (215) to receive image data when motion is detected, a micro controller (205), and a first nonvolatile memory operatively connected to or included in the micro controller (205). The micro controller (205) determines whether received image data should be transmitted to the central controller (105), and the central controller (105) determines whether received image data should be transmitted to a monitoring station (115). The camera units (110) may further be used as standalone units as replacements for motion detectors in existing security systems.

Abstract: A hose-clamp system for securing a hose to an air connector that engages an inflation port of a garment for use in pump therapy for enhancing venous and arterial blood flow of a human foot. The system includes a fitting having an internal stem and an external stem, the internal stem configured to engage an inside diameter of an end of the hose, a cradle configured to received the internal stem and the end of the hose and having opposing locking protrusions, and a seal positioned from the locking protrusions at substantially the length of the internal stem and configured to engage the external stem.

Abstract: Disclosed herein are exemplary embodiments of an impulse therapy garment for use in pump therapy for enhancing venous and arterial blood flow. The garment may be advantageously fitted to a human foot, and may include a rotationally positionable heel-strap, an air inlet connector, separate dorsum straps, or other features. For example, other garments may include a washer having a center hole locatable around the stem and configured to be forcibly retained against the outer surface of the fabric by snap-fit using annular stem protrusions extending from an external surface of the stem. In further embodiments, a garment may include a bladder retention fastener configured to retain an end of the bladder to the fabric to allow substantially differential movement between the fabric and non-retained portions of the bladder during inflation and deflation of the bladder.
