Patent EP-0369361-A2 (EP)
Inventor: HENDERSON GLENN L
IPC: G01N33/58
Filed: 1989-11-11
Abstract: A method for immunoassay of a viral antigen is performed on a membrane precoated with an inert protein. Nonimmunological capture of antigen takes place by absorption onto the coated membrane. Captured antigen binds to a tracer which includes a label conjugated to a specific antibody, the inert protein concomitantly inhibiting nonspecific binding of tracer. The label may be an enzyme which converts a substrate to a detectable product or converts a blocked inhibitor to an inhibitor whereby a second enzyme is inhibited from converting a substrate to a product. The invention includes a kit of materials for performing an assay in accordance with the method of the invention.

IPC: H04H20/76
Filed: 1989-12-05
Abstract: Method and apparatus are provided for transmitting, receiving, and reproducing digital audio signals as discrete carriers similar to standard FM broadcast signals. An audio signal is digitized using, for example, adaptive delta modulation techniques. Several channels of audio information, such as left and right stereo channels and a second audio program ("SAP") channel can all be digitized and incorporated onto the digital broadcast signal carrier. The digitized audio signal may be modulated using multiphase modulation of the carrier of an FM broadcast band signal. A plurality of audio channels may be digitized and transmitted over the airwaves, or over a cable transmission network. Channels of nondigitized audio channels may be interspersed with the digitized audio channels. Source material for the digitized audio channels may be provided to a cable headend over the cable transmission network outside the FM band, and rebroadcast over the cable transmission network in the FM band. Advantageously, an "extended" FM band between 72-120 MHz is employed to provide more channels than the "standard" FM band of 88-108 MHz.

Abstract: An electromagnetic relay comprises an elongated coil bobbin having an axially extending bore and carrying therearound an excitation coil, a generally U-shaped yoke with first and second yoke members, and a generally U-shaped armature with short and long legs connected by a web. The yoke and the armature are magnetically coupled together partly within the axial bore of the coil bobbin to form a magnetic circuit with the excitation coil such that the armature is movable between a set position of closing a relay contact and a reset position of opening the relay contact. The first yoke member extends into the axial bore to define at its free end a first pole end while the second yoke member extending outwardly of the excitation coil to define a second pole end. The short armature leg extends into the bore in an overlying relation with the first pole end, while the long armature leg extends outwardly of the coil in adjacent relation to the second pole end. The armature defines a bearing edge at an inner corner between the web and the short leg and is pivotable relative to the yoke with the bearing end supported on a pivot edge formed at the end of the first pole end. A hinge spring is fitted into the axial bore of the coil bobbin to urge the bearing edge of the armature against the pivot edge of the yoke at an optimum contact pressure, thereby maintaining the bearing edge at a fixed position and therefore insuring an exact pivotal movement of the armature.

Abstract: A method is disclosed for controlling the presentation of nested overlays on a display medium. An overlay function resource is provided which includes its own environment specification which is independent of the space and data environment specifications. Mixing attributes are associated with each overlay and are utilized to determine which overlay space and data are to take precedence and be visible when the overlayed spaces are combined and imaged on a display medium. In a preferred mode of the present invention, the foreground and background of each overlay are separately controlled by the mixing attributes which define the mixing rules for the layered presentation of multiple overlays. Additionally, the order of precedence for displaying multiple overlays may be selectively altered or varied to provide multiple displays and to permit an individual overlay to be repetitively utilized.

Title: Code shift keying communication system
Inventor: ENDO KAORU C O NEC HOME ELECTR
IPC: H04B1/707
Filed: 1990-12-21
Abstract: The present invention provides new arrangements for various components of a CSK communication system: modulator (340), correlators (370, 380), demodulator (390), carrier detection circuit (400) and synchronization control circuit (4l0) which allow accurate demodulation of data from the received signal in the presence of noise and signal deterioration. The modulator (340) permits the CSK system to use two M series codes in which the second code is simply a phase shifted version of the first code. The PN correlators (370, 380), via shift-registers, efficiently output two correlation signals. The demodulator (390) accepts two correlation signals from the correlators , detects auto-correlation peaks in the correlation signals, and uses the peaks to accurately determine whether the received bit has a value of "1" or "0". The carrier detecting circuit (400) detects the presence of data in the received signal and 
allows demodulation of data without exact synchronization of the center of demodulator's monitoring window to auto-correlation peaks. The synchronization control circuit (4l0) generates accurate timing pulses that mark the start and end of each data bit. If auto-correlation peaks appear consistently in one location for the duration of N consecutive data bits, subsequent timing pulses are delayed in accordance with weighted averages of the stored locations of auto-correlation peaks. In one embodiment, separate correlation signal monitoring windows for demodulation and synchronization tracking may be set independently of each other, enabling the demodulator to clearly distinguish between an actual auto-correlation peaks and an inter-correlation peak, and the synchronization control circuit to attain stability by "averaging" out temporal effects of noise.

Abstract: An IC card (1; 20) having a control element, memory element and other necessary components is designed to have the individual components incorporated in a multi-layered integrated circuit, with the topmost layer constituted by an analyzable element (15; 35). This design prevents the functions of the incorporated integrated circuit from being optically analyzed, thus improving the information security of the IC card (1; 20). An information processing apparatus according to the present invention executes encryption of input information and decryption of read-out information in an IC card (1; 20). This allows the same information processing apparatus to perform information encryption of different systems for different information recording media (43). Accordingly, even if a third party finds out the decryption system for or one recording medium (43), he cannot immediately decrypt information on other recording media (43), which has been recorded by the same information processing apparatus. This design is therefore effective in inhibiting the third party from reading out information stored on information recording media (43).

Finally, the blocks containing the partial signals are joined in overlapping fashion, wherein the overlapping areas of the blocks are weighted so that the resultant of the window functions is one. 2.2 To prevent interference in adjacent blocks in the event of frequency changes, the window functions and the length of the window functions are selected according to the changes in frequency of the input signal. 2.3 The method is suitable for processing audio and video signals, which are subjected to data reduction in transmission. <IMAGE>
