Patent EP-0367896-A2 (EP)
Inventor: RUDOLPH DIETMAR PROF DR
IPC: H04H20/36
Filed: 1989-04-29
Abstract: The invention relates to a method for the simultaneous transmission of digital data signals in band-limited transmission channels. In the method, the data signals are rounded off before the transmission in order to achieve an adequate minimum signal/noise ratio between data signals and the other signals to be transmitted. The curve shapes for rounded-off data signals according to the invention are more severely band-limited (approximately 80 %) than the corresponding EBU curve shape for FM-RDS. The time functions of the rounded-off data signal sequences do not exhibit any saddles. The advantages of the method according to the invention consist, above all, a) in the minimum PM -> AM conversion, b) in the minimum bandwidth (referred to the data rate) and c) in the very good eye pattern. <IMAGE>

Abstract: The determination of antibodies by the principle of the immunoassay by incubation with at least three receptors R1, R2 and R3 which are dissolved in liquid phase and of which R1 is an antigen which is able to bind specifically to the antibody to be determined, R2 mediates the binding to the solid phase, and R3 carries a label, separation of the complex which forms out of the solution by binding to a solid phase and measurement of the label in one of the phases, entails using as receptor R2 a conjugate of a receptor which is able to bind specifically to R1 and of a substance S1 which is able to bind specifically, and as R3 a conjugate of a receptor which is able to bind specifically to R1 and of a label, where the immobilisation of the complex which forms takes place via the binding to a component, which is able to bind specifically to S1, on a solid phase. <IMAGE>

Abstract: A method of making a high density interconnect with supercon­ductive lines is provided. A layer of high T c  superconductive material is deposited on an electrically insulative substrate layer (32) of closely matching crystal structure. The super­conductive layer (30) is then photolithographically patterned to define part of an electrical interconnect circuit, and either selectively etched away or ion bombarded to destroy its superconductivity in noncircuit areas. Another layer (34) of insulative material is deposited over the superconductive lines thus formed, and via holes (38) are formed therein. The steps are then repeated for additional layers of supercon­ductive material and insulative material until a complete interconnect is formed. The high T c  material is superconduc­tive at 77 K and has orders of magnitude less attenuation than copper at the same temperature.

Abstract: A programmable low noise frequency modulated signal source including a voltage controlled oscillator (VCO) having a frequency locked loop (FLL) constituting a first feedback path and a phase lock loop (PLL) constituting a second feedback path is provided. The PLL includes a VCO (11), a programmable fractional-N frequency division network (13) and a phase detector (15) for comparing the phase of the VCO output signal with the phase of a reference signal and for producing an error signal to controllably adjust the output frequency of the VCO. The FLL includes a delay line frequency discriminator (10), a loop amplifier (33) and filter (31) to provide a feedback signal to a frequency control terminal of the VCO. The frequency discriminator includes a first signal path having a frequency sensitive time delay network (27) to provide a phase shift as a function of the VCO output signal frequency and a second signal path which includes a voltage controlled phase shifting network (25). The error signal derived from the PLL phase detector (15) is coupled to an input terminal (18) at the voltage controlled phase shifting network (25). The POL error signal in combination with a bias signal adjusts the phase difference between the two frequency discriminator signal paths to set the operating point of the FLL phase detector (29) such that the VCO output signal will have a desired frequency and minimum phase noise.

Abstract: The piston serves to produce a pressure surge in a wind tunnel; it is moved in a suspended manner under the action of a gas pressure of at least 20 bar in a first tunnel from a starting position to an impact surface. A diaphragm at the end of the first tunnel breaks under the compression produced by the piston flying up; the pressure surge released as a result is directed to a foil through a second tunnel filled with test gas. The foil breaks and allows the test gas to flow as a shock wave in the supersonic range into a test chamber. The rear end of the piston has a locking extension which interacts with a fixed holder in the starting position. …<IMAGE>…

Abstract: Disclosed is a splint-like element (1) for use in end-to-end nerve suture to eliminate tension at the anastomosis site and thus allow optimal coaptation between the nerve ends (11,15) to be sutured. The element comprises an elongated body (3) made of a material that is rigid and slightly resilient and is biologically acceptable, such as silicone. The body is long enough to have one end attachable to the epineurium (13) of one of the nerve ends (11) by at least one but preferably two longitudinally spaced-apart sutures (7), and another end attachable to the epineurium (17) of the other nerve (15) end also by at least one but preferably two other longitudinally spaced-apart sutures (9). The element also comprises pieces of reinforcing material preferably consisting of beads (5) of plastic material embedded into the body material wherever this body is intended to be attached to the epineurium to prevent the body material from being torn or otherwise cut by the sutures. In use, two such splint-like elements may be attached symmetrically to the epineurium of the nerve ends while the same are held into contact in order to make the suture site tension free. Then, the nerve ends may be sutured as is known in the medical art to achieve the requested anastomosis.
