Abstract: A tourniquet for occluding blood flow to a limb is improved by the addition of proximal and distal strain gauges. The proximal strain gauge may be monitored under conditions of total blood flow occlusion for time-varying signals indicative of volumetric limb changes arising from the subject's blood flow in the proximal section of the limb. Upon a change in limb occlusion pressure, the signals from the proximal strain gauge can be observed to change also, and the working pressure in the tourniquet can be adjusted safely in response. Automated control systems may further use inputs from a distal strain gauge and/or from a sensor that detects induced pressure changes within the tourniquet to improve the control of the tourniquet working pressure during operation to avoid unwanted blood flow past the tourniquet.

Abstract: A system has a sensor that senses baseline sensor data corresponding to one or more baseline movements of a user and senses dynamic sensor data corresponding to one or more dynamic movements of the user. The dynamic sensor data is captured after the baseline sensor data. Furthermore, the system has an image capture device integrated within a mobile computing device. The image capture device captures baseline image capture data corresponding to the one or more baseline movements of the user and captures dynamic image capture data corresponding to the one or more dynamic movements of the user. The dynamic image capture data is captured after the baseline image capture data. Additionally, the mobile computing device is in operable communication with the sensor.

Abstract: An interactive visualization system has a receiver that receives image data corresponding to one or more biomechanical movements of a user. Further, the interactive visualization system has a processor that performs a biomechanical analysis, via a biomechanical rules engine, of the image data to determine that the one or more biomechanical movements of the user lack compliance with one or more biomechanical rules. The processor generates a virtual sports feedback cue to be rendered, in at least substantially real-time, via a virtual sports performance expert during performance of the one or more biomechanical movements of the user. Finally, the interactive visualization system has a transmitter that transmits the virtual sports feedback cue to the biomechanical data ingestion apparatus so that a rendering apparatus renders the virtual sports performance expert performing the virtual sports feedback cue in a manner visible to the user during the one or more biomechanical movements.

Abstract: A gaming system has one or more biomechanical detection units that detect one or more user biomechanical movements of a real-world user. Furthermore, the gaming system has a processor that is programmed to invoke a game engine to generate a virtual game environment. The game engine also determines a real-world athlete having one or more characteristic biomechanical movements. Furthermore, the game engine generates a virtual avatar corresponding to the real-world user. The game engine also presents one or more virtual stimuli in the virtual game environment to the real-world user. Additionally, the game engine determines if the one or more user biomechanical movements in reaction to the one or more virtual stimuli correspond to the one or more characteristic biomechanical movements within a predetermined tolerance threshold, and generate a virtual game acknowledgement based upon the determination that the predetermined tolerance threshold is met.

Abstract: A method and system for controlling a tourniquet establishes a set of values for a characteristic of an induced pressure pulse in the tourniquet while the tourniquet is inflated to a working pressure which is at a predetermined offset above the limb occlusion pressure. Maximum and minimum thresholds for this characteristic value are established, such that during the working phase of application of the tourniquet the induced pressure pulse is continually monitored and the value of the characteristic is compared to the thresholds. If a threshold is reached the tourniquet is inflated or deflated accordingly to restore the value of the characteristic to within the thresholds. The characteristic of the induced pressure pulse, which may be e.g. pulse height, area under pulse or pulse width at a percentage of peak height, may also be used to determine behaviour of the pressure pulse by noting a variation in the rate of change as the tourniquet is inflated past the limb occlusion pressure.

Abstract: A seat identification system for passengers in a cabin of a commercial airliner. Four sign components, identified as the aisle, mile, row and seat components, are arranged and positioned throughout the airplane in a configuration that allows the passengers to receive information about their seats when needed. The aisle signage markers direct the passengers down the appropriate aisle which leads to their seat. The interval row markers or mile markers provide a general location of the particular row in the aircraft for the passenger's seats. The individual row markers are preferably located in the passenger service unit modules and in viewing channels in order to allow the markers to be visible from the aisle. The seat markers are located preferably on the headrest on each seat and are the final vindication that the passenger is in the correct seat.
