A self-powered medical device, which is operated independently of the public utility network, has at least one voltage source, a signal input for accepting an analog input signal and a signal processing unit. The sampling rate for the input signal or the clock frequency of at least one digital component can be varied. Therefore, the energy demand can be reduced according to the requirements of the...

Ranked breakpoints are defined in a computer program that allow a debugger t o determine whether or not to halt execution of the computer program when a ranked breakpoint is encountered based on the rank of the breakpoint compared to a threshold rank. In a preferred embodiment, the threshold rank is the rank of a RunTo function, and the ranked breakpoints only halt execution of the computer progra...

A multichannel optical spectrum slicer is able to convert a broad-band continuous spectral light into discontinuous multiple wavelength lights. This spectrum silcer comprise a birefringent device (F1) and linear polarizers (P0, P1). A birefringent device (F1) such as a birefringent single-mode optical fiber or uniaxial single crystal has two polarization axes (x, y) each orthogonal to an optical ...

This invention is directed to fabrication of a rechargeable galvanic element with a positive nickel oxide electrode and a negative zinc electrode containing an alkaline electrolyte and a separator. The cathode consists of a nickel foam structure which is repeatedly filled with a nickel hydroxide rich paste made of a PVA-slurry. Then it is suitably compressed to a sheet or tape of defined thicknes...

PURPOSE: Provided is a method for producing a positive plate of lead storage battery which does not induce an environmental problems and provide effect of increasing a life span of the battery. CONSTITUTION: The method for producing a positive plate of lead storage battery, comprises the steps of (i) mixing and kneading lead powders consisting of powdered lead and lead oxide with water and sulfuri...

Welding of two or more steel sheets (1, 2), at least one of which has a protective layer of a material with a low vaporization temperature, is carried out by directing a laser beam (L) on two overlapped flanges (1a, 2a) of the sheets (1, 2), which are clamped in position during welding by means of clamping devices (3). These clamping devices are able to hold the flanges to be welded (1a, 2a) in a ...

Two or more metal sheets (1, 2), at least one of which has a protective layer made of material having a low vaporization temperature, are welded to each other by means of a laser beam after that a gap (G1) has been provided between the sheets to enable the vapours of the protective material which are created during welding to escape. The gap (G1) is obtained by exploiting the elastic return of one...
