Abstract:
Improved automatic chest compression systems which use constricting belts, repeatedly inflating bladders, or reciprocating pistons to compress the chest. A bladder is placed between the chest and the particular mechanism used to compress the chest during CPR. The bladder maximizes the effectiveness of chest compressions.

Methods and systems for monitoring exposure of participants in market research to predetermined products, for example, within a commercial establishment, are provided. The methods and systems employ portable monitors carried on the persons of the participants to gather product exposure data.
Abstract:
An image transfer mechanism for a printer having a printer frame and an imaging drum attached to the printer frame includes a roller arm having a proximal end and a distal end, a transfer roller having a longitudinal axis, and a load arm having a proximal end and a distal end. The axis of the transfer roller is rotatably attached to the roller arm. The proximal end of the roller arm is attached to the load arm between the proximal end and the distal end of the load arm. The proximal end of the load arm is pivotally attached to the printer frame, and a load mechanism applies a load force to the distal end of the load arm to urge the load arm toward the imaging drum. An engaging mechanism selectively urges the distal end of the roller arm toward the imaging drum, which presses the load arm against the load force of the load mechanism.

Devices and methods for cooling an electromechanical chest compression device. A blower or fan forces air through the device and a metal foil distributes heat. The temperature of the device and the patient is measured and the processor controls the operation of the device based on the measured temperature.
Abstract:
A filtration system includes an outer casing that houses a plurality of elongated inner casings, which in turn house a plurality of filters (membranes). The outer casing, inner casings, and filters are disposed relative to one another to provide a three-flow channel system that provides additional feed fluid at one or more of the membrane couplings between membranes of the same inner casing. In preferred systems and methods the feed fluid flow path comprises an annular space between the inner casings and the filters contained in such casings, and in more preferred embodiments the annular space is substantially continuous past multiple filters of the same inner casing. The inner casings may advantageously have openings that fluidly communicate with the lumen of the outer casing, thereby reducing the ratio of couplings relative to the number of filters (the coupling/filter ratio). In especially preferred embodiments the coupling/filter ratio ≦1:2, in more preferred embodiments the coupling/filter ratio ≦1:3, and in still more preferred embodiments the coupling/filter ratio ≦1:4.
Abstract:
A simulated environment includes a motion control system. The motion control system comprises a suspension structure, a housing slidably engaged to the suspension structure such that the suspension controller translates in a planar manner relative to the suspension structure. A rotary component is rotatably attached to the housing. A plurality of winches are attached to the rotary component, the plurality of winches having cables to allow longitudinal movement of the cables parallel to a force of gravity.
Abstract:
The flow of teams of one or more players is controlled through different geographical areas of a mixed virtual reality and physical experience that takes place on an attraction stage. The geographical areas may include rooms, compartments, or other geographical areas through which a team may progress. Within each geographical area, a team may engage in an experience and accomplish one or more checkpoints. Based on the time to achieve each checkpoint, the experience may be shortened or lengthened, either within the particular geographical area or the experience as a whole, to control the flow of the particular team through the series of geographical areas.
Abstract:
Embodiments of systems and methods are provided for a tunable laser device. The tunable laser device may include a tunable Bragg reflector that allows its wavelength to be tuned via temperature and/or pressure. This Bragg reflector may include holographic material in which a Bragg grating may be formed comprising parallel fringes of alternating index of refractions. Temperature and/or pressure changes may be effected in the Bragg reflector by, for example, a thermoelectric cooler and/or piezo transducer.

Abstract:
The present invention is a catheter actuation handle 14 for deflecting a distal end 18 of a tubular catheter body 12, the handle including an auto-locking mechanism, 54. The handle comprises upper and lower grip portions 24a, 24b, an actuator 20, and an auto-locking mechanism, 54. The auto-locking mechanism 54 is adapted to hold a deflected distal end 18 of the catheter 10 in place without input from the operator. When the distal end 18 of the catheter 10 is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator 20. The auto-locking mechanism 54 acts by providing a second force that resists this force from the distal end 18 and holds the distal end 18 in place. As a result, the operator does not need to maintain contact with the buttons 22a, 22b to maintain the distal end 18 in a set position once placed there by actuating the actuator 20.
