Patent EP-0299677-A2 (EP)
Inventor: MARUM JOHN D
IPC: G06F11/20
Filed: 1988-07-07
Abstract: Switching circuitry for automatically connec­ting two sets of terminals in two circuit modules, through a larger set of conductors, some of which may be defective or unavailable for other reasons. The circuitry includes two identical switching matrices, each of which receives signals indicative of the availability status of the conductors, and connects the terminals to an available subset of the conduc­tors. Each switching matrix has an array of switching cells arranged in such a manner that a cell will connect a terminal to a conductor unless the conduc­tor is not available, or unless the same terminal has already been assigned to another conductor, or the same conductor has already been assigned to another terminal.

Abstract: In known cathode-ray picture tubes with triangular or sinusoidal deflection, phase shifts occur between the video signals and the deflection current. It is proposed to fade into the centre of the last forward and return line in each case of each field a reference marker, the position of which on the screen is detected with the aid of sensors, for example of photoelements. The output signals of the sensors are supplied to a reference marker evaluation circuit which emits a correction signal which is proportional to the deviation from the nominal position of the reference markers. This correction signal is used for driving either the read control for a line store or the horizontal output stage. <IMAGE>

Abstract: An aqueous wash solution is buffered to a pH of from 5 to 9 and contains at least 0.01 weight percent of a compound comprising a dodecyl sulfate anion and an alkali metal or ammonium cation, such as sodium dodecyl sulfate. This wash solution is particularly useful in a method for the determination of an immunological ligand. Particularly, it is useful for washing the immunological complex formed between the ligand and a receptor molecule therefor. Unreacted materials can be readily separated from the complex by the washing, particularly if the separa­tion is carried out using a filtration membrane in a test device. A test kit for ligand determination comprises the wash solution as well as one or more receptors for the ligand, at least one of which is labeled for detection. This kit is particularly useful for measuring human chorionic gonadotropin (hCG) as an early indicator of pregnancy.

Abstract: The invention relates to a method for determining the state of corrosion of a metallic buried object (1) which is provided with a corrosion-proof coating (3), an exposed metallic place on the object being connected via a source of direct voltage to an anode (6). An amperemeter (5) is provided in this connection between the object and the anode. According to the invention, provision is made, as known per se, for the coating (3) to consist of modified epoxy resin, and the anode (6) can be a reactive anode, the source of direct voltage then being the potential difference between the materials of the object and the reactive anode. The current flowing between the object (1) and the anode (6) is measured with the source of direct voltage switched off or the current flowing between the object and the reactive anode, which constitutes a reliable measure for the state of corrosion. <IMAGE>

Abstract: An optical transmission line system provided with a first optical transmission line equipment (10) including a pair of a first optical signal transmission unit (11) and a first optical signal reception unit (12) and a second optical transmission line equipment (20) includging second optical signal transmission and reception units (21, 22) which are connected to the first optical signal transmission and reception units (10, 11) through downstream and upstream optical transmission lines (17, 27), wherein when light stoppage is detected by the optical signal reception unit due to the occurrence of a disconnection or other breakage in the optical transmission lines, a corresponding optical signal transmission unit reduces the transmission level of the light transmission signal to a level harmless to the human eye. In order to reduce the level of transmission, the optical signal transmission unit converts all the main signal data bits to "0" and sends only the small number of supervisory information bits to the optical signal reception unit of the other side. The optical signal reception unit operates so as to reduce the level of transmission of the optical signal transmission unit forming a pair with that unit.

Abstract: A method and apparatus for extracting information-bearing portions of an input signal from which is calculated a sliding average magnitude difference function (SAMDF). The signal is coupled to three separate data channels. Each channel is logarithmically spaced from the adjacent channel and time and amplitude normalized to generate a data template containing the information-bearing portions of the signal. In addition, a fourth channel is derived from the first three. Sixteen data measurements are taken, four from each of the four channels with three additional data measurements being derived from the energy envelope of the information-bearing portion of the input signal. The 19 total data measurements represent the amplitude normalized envelope of the signal.
