Abstract: A security system and method of providing security in a retail environment or the like, comprising shopping trolleys associated with the retail enviroment fitted with security devices having a receive-only wireless receiver and a processor. The receiver receiving wireless signals transmitted from one or more transmitters located at various locations around the retail enviroment. By analyzing the wireless signals as it passes thereby, the processor of the security device may determine a location and/or a direction of travel of a shopping trolley to which it is fitted. In addition, an alarm signal may be raised if a predetermined signal or sequence of signals is detected.

Abstract: A portable wound treatment apparatus, for stimulating the healing of superficial wounds, comprises a housing containing a suction pump and a canister for containing fluids drawn from the wound. The housing is supported on a harness or belt worn by the patient. The canister is connected to a porous wound dressing at the wound site via a plurality of tubes, a multi-lumen tube or a combination thereof. A rechargeable battery pack may be incorporated within the housing or externally thereto. The external battery pack may be shaped to balance the housing on the harness or belt. Pressure transducers are provided to monitor and report pressures at the wound site or internal to the canister. Monitored pressures may also be utilized to determine the filled state of the canister and, thereafter, either report this state to the operator or automatically discontinue suction from the wound, or both.

Abstract: A flashlight having a lamp, a power storage element, a switch, and an electronic controller. The controller has a switch input connected to the switch and operates in response to the input to deliver power from the power storage element to the lamp. The controller may be directly connected to each of the lamp, source, and switch. The switch may include several separate contact elements operating sequentially in response to movement of a switch actuator. The controller may provide different illumination levels and functions in response to different pressures and durations of actuation. The flashlight may include a dimmer level control to establish an intermediate “dimmed” output level, and operate to provide the selected dimmed output when the switch is depressed by an intermediate amount, and to provide a greater maximum output level in response to full actuation of the switch.

Abstract: Apparatus is described for stimulating healing of wounds, particularly burns, to the hands or feet. The apparatus comprises an envelope for receiving the affected part of the body. The envelope (12) comprises an air-tight cover which contains a porous pad (22, 24, 26) for covering the wound. Means are provided for connecting the interior of the envelope to a source of suction.

Abstract: A wound therapy device comprising a head and a surgical drape. The head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to and from the aperture. The device may provide medicated fluid to the wound evenly while withdrawing wound exudates.

Abstract: A flashlight has a lamp, a power source, two switches, and a controller connected to the switches. The first switch controls delivery of power to the lamp, and the second switch selects a dimmed brightness level. The first switch may invoke the dimmed level, or a maximum brightness level. The second switch may be a ring rotatable about the axis the flashlight, and either rotatable through a wide range of positions, with sensor circuitry to detect the absolute position, or having a limited range of rotation, with dimmed level selection provided by a duration of momentary rotation in either direction. The second switch may be positioned outside a leak resistant housing, and may include a magnet detectable by magnetic field sensors within the chamber.

Abstract: A method is disclosed. The method comprises combining at least a polymer adhesive material, a thickener, and water to form adhesive compositions having a pH of 4 to 10, and identifying the adhesive compositions having a stringing length of 9 cm or less and one or more of the following properties: a set time of 180 seconds or less, a phase lag of 45 degrees or less, a viscosity of 3,000 to 50,000 cP, a complex shear modulus of 50 to 1000 Pa, and a sag distance of 10 mm or less.

Abstract: The invention is a system that reviews, approves, and implements updates to a primary database that houses a business's chargeable items. A duplicate database has a duplicate of each data entry in the primary database. Prior to implementation, the update is reviewed for compliance with regulatory and local standards and preapproved updates by using the duplicate database as a point of reference. The management service may revise the update before implementing the update into the primary database. Preferably any update that is implemented into the primary database is validated to confirm that the implemented update matches the approved update.
