A MEMS transducer for interacting with a volume flow of a fluid includes a substrate including a cavity, and an electromechanical transducer connected to the substrate in the cavity and including an element deformable along a lateral movement direction, wherein a deformation of the deformable element along the lateral movement direction and the volume flow of the fluid are causally related.

The static mixing element in a flow channel (7) has at least two deflectors (30) disposed on mountings (20) at a distance from the channel wall. The deflectors form an angle W of from 10 DEG to 45 DEG to the main flow direction Z. They have different orientations and the projection FZ of the deflectors in the main flow direction amounts to from 5% to 50% of the channel cross-section F. Cross-flows providing very efficient transverse mixing are therefore produced in a simple manner. When dispensing tubes (20, 21) are used as mountings a very effective mixing device is provided.

A target device for practicing shooting with live ammunition includes a target member, a support member and a connection device that secures the target member to the support member in a manner that positions the target at an acute angle to the ground and provides lateral movement of the target member about a point defined by the connection device so that the target member absorbs the shock of the ammunition strike in a realistic manner and quickly returns the target member to a starting position thereafter.

An optical waveguide device manufacturing method including the steps of: forming an under-cladding layer on a portion of an upper surface of a substrate except for the light emitting element provision region; placing a light emitting element on the light emitting element provision region; and forming a core on the resultant substrate to cover the light emitting element and the under-cladding layer.

Protective gear for protecting an arm or other body part of a wearer, such as a lacrosse, hockey, baseball, or other sports player, or an occupational worker, is provided. The gear can be in the form of an arm guard including a forearm guard, a biceps guard and a sleeve. The sleeve can be joined with the forearm guard and an upper end of the biceps guard, with a lower end of the biceps guard being free from attachment to the sleeve to facilitate radioulnar rotation of the forearm guard and thus the forearm of the wearer. The arm guard can include a low profile elbow cap that is integral with the forearm guard, and generally free floating within and joined with the forearm guard, rather than being a separate component from the forearm guard.

The invention is an apparatus that is a synergistic combination of a windshield and a pilot light assembly for a gas burner heater. The apparatus provides reliable operation of the gas burner heater in high air flow conditions, where the air flow would normally cause the pilot light to be extinguished. The windshield, which is a partially perforated tubular chamber, provides a protected zone against high velocity air infusion for the entire pilot light assembly. The apparatus works in concert with the pilot light assembly, which also has components that provide protection from wind and can be quickly removed allowing quick cleaning and easy maintenance. The major components of the pilot light assembly are a pilot light orifice with a flame, a vented pilot housing (stack), a flame deflector cap, a pilot light gas line, a thermocouple with connecting electrical leads, a pilot base, a mounting bracket, and a windshield that surrounds the pilot light and the thermocouple. The flame deflector cap directs the flame toward the thermocouple. There is also a restrictor plate for restricting the flow of updrafts across the thermocouple and directing the flame toward the thermocouple. The invention is particularly useful in poultry brooder heaters, both ceramic and radiant, which are prone to failure as a consequence of the pilot light being blown out by the fresh air being drawn through the chicken house. The apparatus reduces the time to service a brooder.

The present invention relates to implantable endoluminal prostheses and methods of using such devices in preventing clots migration to avoid ischemic strokes. The implantable endoluminal prosthesis is suitable for deployment from the aortic annulus to the aorta and comprises a self-expandable braided framework able to expand from a radially compressed state in a delivery configuration to a radially expanded state, and a radially collapsible valve body comprising an impermeable material. The self-expandable braided framework is formed of braided wires having a given diameter, and has a proximal end configured to extend toward the heart and a distal end configured to extent toward away from the heart and extending along an axis. The braided framework comprises a main tubular body at the distal end of the self-expandable braided framework, a neck at the proximal end of the self-expandable braided framework, a transition portion extending between the proximal end of the main tubular body and the distal end of the neck. The main tubular body 3 and the neck comprise a lumen in a cylindrical form with a circular cross-section and a constant diameter respectively, and the diameter of the main tubular body is larger than the one of the neck. The main tubular body, the neck and the transition portion consist of an integrated structure comprising plurality of layers of made of biocompatible material, being devoid of any impermeable cover layer, and forming a wall having a thickness. The valve body is placed within the lumen of the neck.

A side-window roll-up shade for the front doors of motor vehicles which has a relatively short wind-up shaft housed in the region of a back edge of the window in the door frame. A short guide rail extends above the top edge of the window for guiding a slide, which is connected to a tip of the roll-up shade. For driving the roll-up shade, an electric drive with a cord is provided, with the cord extending around the window opening as a closed loop.

In the case of a lighting fixture (100) with lighting means having LEDs (5) arranged one behind the other in the longitudinal direction (I) of the lighting fixture (100) and a reflector (10) which is concave in a plane perpendicular to the longitudinal direction (I) of the lighting fixture (100), the lighting means are arranged in the upper region (11) of the reflector (10) such that they emit light onto the reflector (10) in essentially the opposite direction from a light emission direction (A) of the light fitting (100), wherein a diffuser (20) is arranged below the lighting means and extends as far as the reflector (10).

Thereby multiple antechambers, which are connected in series one behind another to conduct media, are connected upstream from the measuring chamber.

The present invention is to offer a fan diversion structure which is adapted to be disposed on a fan, and the fan diversion structure comprises at least one deflector and at least one connecting part. The deflector, which is adapted to be disposed across front of an air outlet of the fan, is disposed on one side next to a center of the fan and without overlapping the center of the fan, wherein the deflector extends outwardly so as to deflect an airflow to the side direction of the fan. The connecting part is adapted for connecting the deflector to the fan. Thereby the airflow from the fan not only converges in the axial direction, but also moderately extends to the side of the fan so as to increase the blowing angle and enhance convection efficiency around the fan.

A transversal load insensitive optical waveguide includes a primary section having a core. The waveguide may further include an outer cladding. The primary section includes a primary section surface and the outer cladding includes an exterior surface mechanically attached to the primary section surface by an interior cladding structure forming a mechanical connection. The cladding structure is such that for at least part of a distance between each two radial corresponding points on the exterior surface and the primary section surface respectively, the mechanical connection deviates from being radial, so that a radially-directed load on an exterior surface of the outer cladding is deflected by the cladding structure.
