摘要:
A leak detector comprising a base appliance provided with a gas detector, a vacuum pump, and a control device. A sniffer probe is connected to the base appliance. A test leak device containing the supply of test gas is arranged in a separate sub-housing. The sub-housing also contains a temperature sensor, a processor, and a data memory. The processor corrects the measured temperature according to a sample, and modulates the light of a light barrier. The processor is connected to the control device in the base appliance by a data cable.
摘要:
A method and apparatus for reducing the visual discomfort of the illumination generated by imaging scanners. The method includes (1) turning on a driving current for a illumination source during each of a series of exposure periods to provide illumination directed toward a target object; (2) capturing an image from the target object with photosensitive circuitry during at least one of the exposure periods; and (3) generating a pulse-width-modulation driving current that has a duty cycle changing with time between two consecutive exposure periods for making perceived gradual illumination changes between the two consecutive exposure periods. The duty cycle decreases from the value of 100% to a minimal value after each of the exposure periods and increases from the minimal value to the value of 100% before each of the exposure periods.
摘要:
An omnidirectional scanning system and method are provided for reading at least one optical code within a field of view of the scanning system and oriented in an orientation included in a set of multiple orientations. The omnidirectional scanning system includes at least one processor for operating the scanning system in at least two modes including a first mode which is a non-restricted omnidirectional scan mode for reading the at least one optical code oriented in any orientation of the set of multiple orientations, and a second mode which is a restricted omnidirectional scan mode for reading the at least one optical code oriented in an orientation of a selectable reduced set of the set of multiple orientations. The method includes the steps of operating the system in a mode selected from the at least two modes including the first mode and the second mode.

Antibody to endostatin protein that is an inhibitor of endothelial cell proliferation, capable of inhibiting angiogenesis and causing tumor regression, that is approximately 18 kDa as determined by non-reduced gel electrophoresis, and approximately 20 kDa as determined by reduced gel electrophoresis and corresponds to a C-terminal fragment of collagen type XVIII, and methods of detecting and treating angiogenesis-related disease therewith.
摘要:
An integrated magnetoresistive semiconductor memory system, in which n memory cells that contain two magnetic layers each separated by a thin dielectric barrier, and associated word lines and bit lines that cross one another are vertically stacked in n layers. The system further contains a decoding circuit for selecting one of the n memory layers. The decoding circuit, on both ends of a word line or a bit line, is provided with one configuration each that contains n layer selecting transistors for selecting one of the n memory layers, and with a line selection transistor for selecting the respective horizontal word line or bit line on which a voltage is to be impressed.

Propylene polymers containing from 0 to 2.5% by weight of C2-C10-olefin comonomers have an Mw of from 350,000 to 1,000,000 g/mol, an Mw/Mn of from 4 to 10, a proportion by weight of the polymer fraction having a viscosity number of from 500 to 1400 ml/g of from 20 to 80% of the total polymer and a proportion by weight of a polymer fraction having a viscosity number of from 200 to 400 ml/g of from 80 to 20% of the total polymer and an isotactic sequence length of from 50 to 100.
摘要:
An arrangement for and a method of reading bar code symbols on a target to move a light beam emitted by a light source in a multiple line, scan pattern during a scan period in a first operational mode. Upon selection of a second operational mode by a user, a controller intermittently operates and energizes the light source to emit the light beam for a working time period which is less than, and a fraction of, the scan period to generate a single scan line across the symbol.
摘要:
The invention relates to a process for preparing clonogenic fibroblasts, with tissue being removed from the donor and the individual cells being isolated from the tissue, the resulting cell suspension being strained, the cells which are contained in the cell suspension being washed and the cells being converted into a tissue culture, with the exception of the isolation of individual cells by mechanical comminution, followed by an enzymic treatment with collagenase alone, and with at least one gene being inserted into the fibroblasts by means of the transfection, which gene encodes a biologically active protein, preferably a therapeutically active protein, for example a growth factor, a hormone, an enzyme, a coagulation factor or a coagulation inhibitor.
