Title: Data modem system
IPC: H04L27/233
Filed: 1985-11-22
Granted: 1990-09-05
Abstract: A data modem system incorporates, digital filters (11, 21, 59, 60) in transmitter and receiver units having intermediate frequency stages which operate at a frequency which is an integral multiple of the modulation symbol rate. This enables filtering, modulation and demodulation to be carried out in a relatively simple manner using digital hardware, with conversion between different forms of modulation such as QPSK, BPSK and offset BPSK being possible without substantial hardware modifications. In one embodiment of the invention, the receiver employs a phase estimating circuit (124) to compensate for phase and frequency errors arising when a free-running local oscillator is used as an alternative to one controlled via a phase-locked loop.

Abstract: Arc-over in the cathode ray tube (21) of a digital television receiver produces a large current pulse which, when it discharges via the chassis ground, disrupts the reference ground potentials of other circuitry coupled to the chassis ground. The affected circuitry includes digital data storage elements which may experience random state changes caused by the fluctuating ground potential. The CRT arc-over condition is detected by circuitry (460-466) which applies a pulse to the reset terminal of a microprocessor (440), causing it to restore the potentially corrupted data in the data storage elements using preset data stored in a less volatile programmable read only memory (452).

Abstract: Highly sensitive methods for assaying for biopolymers, such as by immunoassay or nucleic acid probe hybridization assay, and compositions for carrying out the methods, are provided. The methods employ as reporter group a RNA capable of being autocatalytically replicated by an RNA-dependent RNA polymerase, such as the replicase of bacteriophage Q beta . The high sensitivity of the assay methods is due to the rapid, exponential increase in concentration of such a replicative RNA, associated specifically with biopolymer analyte, that can be achieved by autocatalytic RNA replication.
