This invention relates to a “high lower alcohol content” (>40% v / v of a C1-4 alcohol) liquid composition able to be either dispensed as a stable foam with the use of non-propellant foam dispensing devices from non-pressurized containers or as an alcohol gel composition which does not use thickener and gelling agents that leave undesirable deposits or a sticky after-feel and that has a final viscosity less than 4,000 cps. The liquid compositions comprise an alcohol, C1-4 (>40% v / v), a fluorosurfactant of at least 0.001% by weight to prepare a foamable composition or from 0-2.0% to prepare a gel-like composition of a final viscosity less than 4,000 cps, 0-10% w / w of additional minor components added to obtain the desired performance (a foamable composition or a gel-like composition with a viscosity less than 4,000 cps), and the balance being purified water. The compositions may include emulsifier-emollients and mosturizers, secondary surfactants, foam stabilizers, fragrances, antimicrobial agents, other type of medicinal ingredients, and the like ingredients or additives or combinations thereof commonly added to alcohol gels or foams, aerosol compositions or to toiletries, cosmetics, pharmaceuticals and the like.

A system and method for inputting motion measurement data into a computationally based device are provided. In a first version three-axis accelerometer determines components of an inertial force vector with respect to an orthogonal coordinate system. The accelerometer includes a sensor die made of a semiconductor substrate having a frame element, a proof mass element, and an elastic element mechanically coupling the frame and the proof mass. The accelerometer also has three or more stress-sensitive IC components integrated into the elastic element adjacent to the frame element for electrical connectivity without metal conductor traversal of the elastic element.

The detector (110) comprises:at least one transversal optical sensor (130), the transversal optical sensor (130) being adapted to determine a transversal position of at least one light beam (138) traveling from the object (112) to the detector (110), the transversal position being a position in at least one dimension perpendicular to an optical axis (116) of the detector (110), the transversal optical sensor (130) being adapted to generate at least one transversal sensor signal;at least one longitudinal optical sensor (132), wherein the longitudinal optical sensor (132) has at least one sensor region (136), wherein the longitudinal optical sensor (132) is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of the sensor region (136) by the light beam (138), wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam (138) in the sensor region (136);at least one evaluation device (142), wherein the evaluation device (142) is designed to generate at least one item of information on a transversal position of the object (112) by evaluating the transversal sensor signal and to generate at least one item of information on a longitudinal position of the object (112) by evaluating the longitudinal sensor signal.

3D accelerometer for measuring three components of inertial force (or acceleration) vector with respect to an orthogonal coordinate system, which has high sensitivity due to a big proof mass located within a cavity beneath the surface of the sensor die. The size of the cavity and the size of the proof mass exceed the corresponding overall dimensions of the elastic element. The sensor structure occupies a very small area at the surface of the die increasing the area for ICs need to be integrated on the same chip.

The present invention relates to an improved catalyst for direct conversion of methane to ethane and ethylene, a method for producing the catalyst and a process making use of the catalyst.

A photovoltaic cell includes a first substrate having on its surface a first electrode layer having on its surface a semiconductor film on which a photosensitizer is adsorbed, and a second substrate having on its surface a second electrode layer. The first and second substrates are arranged so that the first electrode layer overlaid with the semiconductor film and the second electrode layer are opposite each other with an electrolyte disposed therebetween. Spacer particles are interposed between the semiconductor film and the second electrode layer, and at least one of the electrode-layer-having substrates is transparent. A coating liquid for forming the semiconductor film includes both a component for forming the semiconductor film as well as the spacer particles, dispersed in a dispersion medium.
