A bariatric device includes a body having a wall defining a lumen, the wall configured to generally conform to the shape and size of at least one chosen from i) the abdominal portion of the esophagus, ii) the esophageal-gastric junction, and iii) the proximal cardiac portion of the stomach, with the wall adapted to exert pressure on the at least one chosen from i) the abdominal portion of the esophagus, ii) the esophageal-gastric junction, and iii) the proximal cardiac portion of the stomach, thereby influencing a neurohormonal feedback mechanism of the patient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food.

The present invention relates to an electronic circuit for measuring small amounts of charge or small electrical currents. One embodiment of the present invention provides an electronic circuit for measuring current or charge that can be used with a variety of sensing media (including high impedance sensing media) that produce a signal by either charge or current production or induction in response to physical phenomena occurring within the sensing media. In another embodiment, the voltage level (bias) of either the sensing or reference electrode can be switched relative to the other upon receipt of a triggering pulse. This changes the polarity of the electric field to cause charge of the opposite polarity to be driven to the sensing electrode, thereby eliminating the need to electrically connect a discharge path to the sensing electrode to clear the charge accumulated at the sensing electrode. This can be supplemented by capacitively coupling a compensation signal to the sensing electrode to cause the amplifier output signal to lessen in magnitude below a threshold level that permits additional charge or current measurements of the same polarity before performing bias reversal. Alternately or in combination with bias reversal and capacitive compensation, sensor performance can be improved by minimizing inaccuracies caused by leakage currents or current drawn from the sensor. Other methods of reducing leakage currents that can be used alone or in combination with the aforementioned features include the use of guard rings, physical switches or relays, the controlled creation of charges or currents of a specific polarity in a specific region of the sensing medium, controlled leakage over the surface of an insulator, and controlling the environment in which the circuit operates.

Provided is an aerodynamic profile for use in gas turbine airfoil and a turbine blade comprising such profiles. The profiles counteract a reduction in area between adjacent airfoils due to an increase in coating thickness. A plurality of radial sections forms both coated and uncoated nominal profiles of the airfoils. The sections are located within a tolerance measured in any direction perpendicular to an airfoil stacking line extending radially from a central axis and defined by X, Y, and R Cartesian coordinate values in inches. The R values are measured perpendicular to a plane normal to the airfoil stacking line with R values of zero at a lowermost radial section and increasing in the radial direction. The X and Y values are measured perpendicular to the airfoil stacking line.

Nanocrystals having an indium-based core and methods for making them and using them to construct core-shell nanocrystals are described. These core-shell nanocrystals are highly stable and provide higher quantum yields than known nanocrystals of similar composition, and they provide special advantages for certain applications because of their small size.

A calibration system is provided for calibrating frequency domain reflectometers in the field by using both the scattering parameters of the multi-port junction determined at the factory and changing the offset and gain terms used in generating a complex reflection coefficient by using internal calibrated loads so that heavy, cumbersome external calibrated transmission lines are not required. In one embodiment the internal calibrated loads include RLC circuits and in another embodiment the internal calibrated loads include attenuators. Further, retesting or recalibration does not necessitate reconnecting the cable under test, which may remain connected to the reflectometer's test port throughout the procedure.

A wall-mounted medications cabinet has at least one, and preferably up to four locking drawers, each with a removable bin holding the medications for a given patient. The drawers are each independently openable electronically. This can be accomplished using an incorporated PC with a touch screen monitor, or authorized access can be obtained via a network. The cabinet may be connected using USB or ethernet interface. A key lock can provide access in the event of a power failure.

An all electric vehicle that produces zero CO2 emissions and capable of traveling an unlimited amount of mileage is presented. This vehicle is considered air and electric because it uses a wind turbine generator, compressed air and a high voltage battery to generate electricity to power the DC motors that drive this vehicle. Therefore this vehicle is called the Wind Turbine Generator Air Electric Vehicle (WTGAEV). There exists an integrated system that enables this vehicle to maintain a consistent energy supply to automatically recharge the high voltage battery. This integrated system consists of a wind turbine generator (WTG), air motor, air compressor, air tank, and battery. The power train receives its energy from the motion of the vehicle. When the vehicle is in forward motion the air flow from the nose of the vehicle is collected and directed toward the blades of the WTG which generates electric.

The prosthetic replacement may also include portions that replace one or more of the natural spinous process and the two natural transverse processes. If desired, the prosthesis replacement may also replace the natural pedicles. A method for replacing a posterior element of a vertebra is also provided.

A system for fighting a fire in an enclosed space has at least one container (3) for holding a fire extinguishing agent under pressure. A pipe system connects a container outlet to a discharge in the enclosed space. A controllable flow control valve (5) in the pipe system is responsive to a flow control signal generated by a control unit (4) in response to sensed characteristics (pressure and / or temperature) of the agent. A trigger action initially opens the container to the pipe system. The valve is initially held open until concentration (A) of fire extinguishing agent in the enclosed space is sufficient to suffocate a started fire. Thereafter, the valve is opened intermittently to maintain a lower concentration of fire extinguishing agent in the space sufficient to prevent rekindling. More than one container may be used but only one is equipped with a valve controllable by a control unit.

A flow rate detection method using a heat signal that enables accurate flow rate measurement by eliminating sources of measurement error is provided. The flow rate detection method, using a heat signal, of writing a temperature-change heat signal in a medium traveling through a channel and detecting the heat signal with heat signal detecting means provided at a position away from the writing position, to measure a traveling speed of the medium, wherein first and second temperature sensors 20A and 20B, which are separated by a predetermined distance L, are disposed downstream of the writing position, and the traveling speed is calculated from a time difference at which the two temperature sensors 20A and 20B detecting the heat signal and from the distance L.

The described method and system allow a service provider to remotely interact with a vehicle analysis system, high voltage battery contactors, and other vehicle systems to eliminate certain sources of inconvenience for service personnel and users. For example, when the high voltage battery contactors are disconnected inadvertently or as a precaution, they may later need to be safely reengaged to allow the user to drive the disabled but otherwise operational vehicle. Conversely, when an electric vehicle has become disabled and needs to be towed or serviced, the disengagement of the high voltage battery contactors as well as the activation or deactivation of related systems will assist the servicing entity in properly moving and servicing the vehicle.
