Title: Enzyme-immuno assay for the detection of pathogen specific antibodies and test-kit for performing this assay
Inventor: SCHMITZ HERBERT DR PROF
IPC: G01N33/53
Filed: 1980-07-18
Granted: 1984-02-02
Abstract: A highly sensitive enzyme immunoassay procedure is disclosed for determining IgM-, IgA-, IgG- and IgE- antibodies which are specific to antigens by coating a solid support with an antibody which selectively binds the antibody to be determined in a serum specimen and reacting the selectively bound antibody with an enzyme labeled microbe or antigen and then determining the enzyme activity of the reaction product as a measure of the antibody to be detected. As the antigen can be effectively labeled a relatively impure antigen can be labeled and used in high dilutions resulting in a very sensitive assay; purification by column chromatography is unnecessary. A kit for conducting the assay is also disclosed.

Granted: 1990-10-11
Abstract: In a secure communications system, a key number which is changed periodically, e.g. monthly, and a random number from a random number generator are combined and used as a seed to reset a PN sequence generator, with the output of the generator being used to control encryption of transmission data in a signal processor. The key is also provided to a first encipherer to encipher the random number for transmission with the encrypted data. At the receiver, the key is provided on common to a decipherer for deciphering the random number and a PN sequence generator which is periodically reset by the combination of the key and random number in the same manner as in the transmitter. The PN sequence is then used to decrypt the information. User identification codes are stored in the transmitter and are used to encipher the key, with each employing its ID code to decipher the key. The user ID codes are known only to the system operator, so that not even a particular user can know the key.

Abstract: The invention starts from a device for dividing high-frequency energy between two mutually decoupled outputs (A1, A2) with matched impedances, with a matching transformer (Ü1) and a differential transformer (Ü2) as well as a decoupling impedance. To achieve a broadband high decoupling of the two outputs (A1, A2) with good matching of all terminals in as simple and inexpensive a manner as possible, two possible circuits are proposed: In the first embodiment the decoupling impedance is an ohmic resistor (R1) which is connected between the connection point of the matching transformer (Ü1) and one of the two outputs (A1, A2) in the case of symmetrical distribution, and the output with the higher resistance in the case of non-symmetrical distribution, its magnitude and the location of the tapping being selected in such a way that both the decoupling of the two outputs (A1, A2) and the return loss have an optimum value at the output with the higher resistance. In the second embodiment of the distribution network according to the invention, the series circuit of an ohmic resistor (R2) and a reactance (L) with a resonant frequency of approximately 50 MHz is connected between the two outputs (A1, A2). <IMAGE>

Title: Electronic accelerator pedal for a motor vehicle
Inventor: HAHN KLAUS DIPL ING
IPC: F02D41/14
Filed: 1985-07-18
Granted: 1988-11-10
Abstract: The accelerator pedal comprises a required value transmitter (2) connected to the pedal which propels via counter (3) an adjusting motor for a throttle flap (2). A measured value transmitter (10) mechanically connected to the throttle flap delivers the measured value to a difference device while the counter provides the required value.  The thus maintained normal difference is converted by a regulator whereupon the regulator controls a final stage (6) of the adjusting motor. To balance the min. and/or max. cross-sectional opening of the flap, the counter adjusts the required value for the regulating circuit until the regulator output indicates either a driving of the throttle flap in the direction of the end-stop or a normal balancing condition. The thus maintained approximate required value is stored in the counter.
