Patent CA-2139298-A1 (CA)
Inventor: ATTRIDGE RUSSELL G JR
IPC: F24F13/14
Filed: 1994-12-29
Abstract: A fail-safe closed damper for installation in a system of ducts. The damper includes at least one damper blade connected to a spring-loaded shaft. A poweractuated unit is employed to disengage a coupling which interconnects the spring-loaded shaft to an operating linkage. The use of the power-actuated unit ensures that the damper will be tripped at the appropriate predetermined temperature and will not be affected by the large frictional forces imparted on the components of the damper by the biasing spring or by such external factors as dust, humidity and dirt. The damper also employs a sensor which may be mounted at any remote location within the ventilation system. Alternatively, a plurality of interconnected sensors capable of providing additional sensing capability may be employed.

Title: Rapid immunological test for the visual determination of progesterone in fluids
Inventor: ARNSTADT KLAUS-INGO
IPC: G01N33/74
Filed: 1993-11-26
Abstract: The proposed process for the qualitative/semi-quantative détermination of progesterone in a biological fluid on an ELISA principle comprises the following steps. A few drops of the fluid to be examined are taken, they are diluted with an aqueous sample diluent solution, this mixture is put into contact with a surface coated with a specific antibody and a progesterone-enzyme conjugate solution is added which preferably reacts with still free bond positions of the antibodies which are fixed on a surface. Incubation mixture and unbonded reaction partners are removed by being washed off the surface and the bonded enzyme is detected by colour reaction. The colour developed is a measure of the progesterone content of the fluid to be examined. The process of the invention is particularly suitable in a fast test for the simple and reliable detection of the insemination and conception time and monitoring the pregnancy of domestic animals. Thereby it is possible for the first time very reliably to distinguish between the oestrus and pregnancy period and intermediate the period of low progesterone concentrations and largely avoid the many faulty diagnoses and interpretations commonly made with prior art processes.

Abstract: According to this invention, there are provided a multilevel weighted transmission method which allows error correction encoders to be reduced to one without error propagation and an apparatus using this method.          The multilevel weighted transmission method is such that a plurality of hierarchic information source data strings are subjected to different multilevel weighted coding and modulation by a trellis-coded modulation scheme and the resulting strings are transmitted, and on the reception side, the received signal is subjected to the multilevel weighted demodulation and decoding according to the transmission side to obtain the original hierarchic information source data strings.          When the specific first subsets are allocated to the hierarchic levels of the transmission channel in the multilevel weighted transmission and time-division multiplexed at a predetermined ratio, the order of time-division multiplexing the hierarchic levels of the transmission channel is ascending order of the quality of transmission error characteristic.

Title: High speed simulcast system using adaptive compensation
Inventor: HO PAUL KAR-MING
IPC: H04H20/67
Filed: 1994-09-19
Abstract: In a simulcast communication system (26), a method and apparatus for compensating differences in propagation time, lack of syn-chronization in transmitters, and multipath fad-ing to recover data transmitted to a receiving device. In a simulcast communication system (26) that comprises a plurality of transmitters (32a, 32b, 32c), a receiver (36) includes a dig-ital signal processor (DSP) (86) that processes a demodulated received signal to adaptively compensate for changes in the channel through which a multipath signal is propagated from the transmitters to the receiver. In one embod-iment, the DSP comprises a decision feedback equalizer (300). An error signal is produced by the equalizer through a comparison of the estimated symbols with symbols most likely transmitted, for use in updating filter coeffi-cients used by the equalizer in processing the received signal. Another embodiment imple-ments a Viterbi algorithm to make decisions of the most likely data symbols in response to estimates of the channel impulse response. Using any one of these embodiments, a linear modulated signal can be decoded to recover the data transmitted, even though the received signal has been degraded by propagation in a multipath fading channel.
