Abstract: A method and apparatus to monitor the weight of a silo or tank is disclosed. The system is adapted to be attached to a leg of the silo and comprises a load cell, a support member anchored to the ground and a lifting device attached to the load cell and to the support member. The load cell comprises two extremities that are attached to the silo leg and comprises an aperture there between. The aperture is preferably threaded to receive the lifting device, such as a bolt. The bolt is rotated using a tool as to induce a movement of the load cell along the axis of the bolt thereby lifting the load cell and the attached silo leg. Strain gauges are attached to the load cell to measure the variation in an electric or optical signal that is translated in human readable data using a monitoring device.

Abstract: A method and apparatus are described for measuring the concentration of a gas with an absorption band in the ultraviolet range. The device includes an absorption chamber containing a gas, a light source, a selected optical bandpass filter, and ultraviolet photodetectors. The gas concentration is measured by the ratio of a transmitted intensity to an incident intensity with the Beer-Lambert Law relation. A second light source may be used for a compensation signal. A second method periodically changes the absorption coefficient by inserting a transparent material in the absorption path to measure the optical compensation signal. A third method periodically shortens the optical absorption path by moving the active detector closer to the light source to measure the optical compensation signal. The fourth method uses an optical element to deflect the optical beam to create a shorter absorption path as a reference for the incident signal using one detector.

Abstract: A method and system to setup and to manage one or more role-playing game at a single physical location using mobile device is disclosed. The game is distributed and animated on multiple devices connected in real time to a network, preferably to the Internet. Although participants are gathered at the same time and location, each one uses a personal mobile device programmed to provide to the participant instructions and commands relating to the game. To provide instructions, the system comprises a game server configured to provide the game intelligence. The system further comprises mobile devices of each participant connected to the game server during the game play.

Abstract: A set of biomarkers have been identified that allows one to predict subjects who will respond to an exercise regime in term of cardiorespiratory fitness as assessed by maximal oxygen uptake. These predictions may be used, for example, to predict risk of cardiovascular disease, to design a more effective program for cardiac rehabilitation, to predict capacity for athletic performance or physically demanding occupation, and to predict ability to maintain functional capacity with aging using exercise.

Abstract: The invention concerns bubble level meter having a pneumatic tube connected to a gas generator and to a pressure sensor. A deflecting valve is interposed along the pneumatic tube, for deflecting the air outlet at a predetermined height from the usual lower outlet of the tube. A control circuit controls the deflecting valve and the gas generator based on predetermined set values, processes the pressure measurements obtained from the pressure sensor, checks the calibration of the sensor on the basis of the measurements and the differences in height between the tube outlet, and generates level data based on the processed pressure measurements and a calibrating coefficient. Another valve interposed between the sensor and the tube and monitored by the circuit control, enables to take into account the possible drift of the sensor.

Abstract: A user-interface (UI) device allows the assignment of multiple parameter values to a multiple-selection of objects through a familiar UI mechanism. A multiple selection of objects is made. A object inspector is opened such as would normally be used to enter single values to be applied to properties of all the selected objects. For example, a group of graphical objects is selected and a line-weight parameter is adjusted to make the lines of the objects heavier. According to the invention, the same type of inspector device may be used to apply multiple values by providing for the indication of a function definition instead of an explicit value in a field normally used to enter a single value. The text boxes normally used for entry of values are provided with the ability to accept symbolic notation, e.g, a string, to indicate value ranges instead ofjust discrete values.

Abstract: A device has a valve (21) activated by hydraulic fluid in opposition to a resilient restoring element (27) and blocking off an outlet in the bottom of a cylinder ( 3 ) when the fluid, responsive to being compressed by a piston (5), exerts a specified pressure subsequent to an involuntary movement on the part of a femoral amputee wearing the device so as to correct the gait of the amputee.

Abstract: A detector for charged particles, i.e. secondary electons ir ions emitted from a bombardment area of a specimen in an instrument such as a scanning electron microscope or analytical instrument, consists of a collector, e.g. a scintillation surface highly charged with a voltage of the opposite polarity from that of the particles, for receiving the particles and providing an output proportional to the number thereof. A grid, charged with a voltage of the same sign as the scintillation surface, but to a lower value, is located between the scintillation surface and the bombardment area, and a probe in the form of a wire electrically connected to the grid projects into the vicinity of the bombardment area which is in a confined space between the specimen and the instrument. The result is to set up an electrostatic field around the wire, causing a significant number of the charged particles to orbit the wire and travel to the scintillation surface.
