A gas flow rate verification apparatus is provided for shared use in a multiple tool semiconductor processing platform. The gas flow rate verification apparatus is defined to measure a pressure rate of rise and temperature within a test volume for determination of a corresponding gas flow rate. The apparatus includes first and second volumes, wherein the second volume is larger than the first volume. The apparatus also includes first and second pressure measurement devices, wherein the second pressure measurement device is capable of measuring higher pressures. Based on the target gas flow rate to be measured, either the first or second volume can be selected as the test volume, and either the first or second pressure measurement device can be selected to measure the pressure in the test volume. Configurability of the apparatus enables accurate measurement of gas flow rates over a broad range and in an time efficient manner.

A mechanism for coupling a coaxial waveguide to another waveguide. The mechanism includes a lower or matching waveguide and an impedance transformer. A coaxial port couples the coaxial waveguide to the matching waveguide. The matching waveguide has a waveguide impedance which is close to the impedance of the coaxial waveguide. This arrangement allows matching between the coaxial waveguide and the matching waveguide over a wider frequency band. The impedance transformer couples the matching waveguide to the other waveguide. The impedance transformer comprises a single-stage, double-stage, or multi-stage transformer. The mechanism is suitable for coupling an antenna to a coaxial cable interface in a radar or microwave based level measurement or time of flight ranging systems.

In an antenna for a level meter employing the radar principle, a fastening device is provided for detachably mounting a dielectric insert in the antenna. The fastening device may be a continuous clamping collar that clamps the dielectric insert in place in the antenna. This offers a simple, universally employable possibility for fastening a dielectric insert in the antenna.

The dielectric antenna makes it possible to measure the surface of a medium with an essentially consistent measuring accuracy in that the lens (3) has an outer component (4) and an inner component (5). The outer component (4) has a radiating surface (6) that is spherical and an inner surface (7) that is spherical, and the inner component (5) has a contact surface (8) that spherical. Furthermore, the antenna is usable as part of a fill level sensor operating on the radar principle.

The present invention relate to a horn antenna at a radar level gauge for determination of a level of a surface of a medium stored in a tank and a method of making a horn antenna which is mechanically constituted such that the horn antenna will withstand the environment of the tank interior. The antenna comprises a first conductive housing (7) having a wave guide port (8), which is connectable to a wave guide, a first aperture (10), which is separated from the wave guide port (8) and a fist divergent section between the wave guide port (8) and the first aperture (10). A dielectric body (11) is arranged inside and essentially filling the first conductive housing (7), which body (11) displays a free end (12) in the area of the first aperture (10). The horn antenna is characterized in that around the first aperture (10) is arranged a locking device (13), which is arranged to fix the dielectric body (11) in the first housing (7) and that in the area of the locking device (13) is arranged at least one flexible sealing element (16) between the dielectric body (11) and the first cover (7).

A passive wireless sensor and control transmitter subsystem is provided for operating irrigation or other hydraulic system. The system includes a master module unit hardwired to and in communication with an existing hydraulic system controller, and a field module unit that is hardwired to and in communication with field electromechanical control devices such as valves, solenoids and servo motors, and field sensors indicating, for example, atmospheric conditions. The master module unit and field module unit communicate with digital wireless communication and can act as a simple wireless bridge providing pass through data connectivity. The master module and field module units are capable of digitizing input signals from the devices to which they are hardwired and transmitting them to the opposite module; they are further capable of recreating the digitized signals received back into the analog form to reproduce the original input signal and communicating it to the device to which it is hardwired. Full duplex communication enables remote sensors to be hardwired to the field modules unit rather than directly to existing control apparatus, as well as being able to transfer valve, pump and relay status back to existing control apparatus. One embodiment enables the subsystem to receive sensor inputs and process them accordingly even though the hydraulic control system may not be capable of utilizing them. Supplemental functionality may be added to an existing hydraulic control system by including the WSCX and its system features of sensor functionality and control.

A torsion- and bending resistant boom formed of beams running the length of the structure, a set of pierced, transverse flanges arrayed along, and substantially perpendicular to, the length of the structure, a continuous longitudinal member running the length of the structure, piercing the flanges, and several further longitudinal members, outward of the first member. The longitudinal members are welded to the flanges. An elevatable mast assembly raises and lowers the boom, and has a mast and guides formed of hollow tubes, and rollers between the guides and the mast, the rollers transferring torque loading to the guides.

The present invention provides an apparatus and method for determining the magnitude of linear and rotational acceleration of an impact to a body part. The apparatus can be used with protective sports equipment, such as a sports helmet, wherein the apparatus includes a battery, a number of accelerometers positioned proximate to the outer surface of the head, and an electronic device with a processor and a transmitter to transmit data received from the accelerometers. To maximize the battery life and minimize power consumption by the electronic device, the apparatus includes a power management system with a sensor assembly. The sensor assembly sends a first signal to the electronic device to initiate operation when the sensor assembly detects the presence of an object with the helmet, and a second signal to the electronic device to cease operation when the sensor assembly detects the absence of the object.
