Title: Peristaltic pump motor drive
Inventor: MATTHEWS JOSEPH B
IPC: F04B49/06
Filed: 1990-11-28
Abstract: The present invention provides a drive signal for a peristaltic pump motor (42).  A first circuit is provided which generates a first series of pulses (SF) at a given frequency.  A second circuit is provided which generates a second series of pulses (M4) having a frequency higher than the frequency of the first series of pulses.  A third circuit is provided which generates a third series of pulses (M3A) having a frequency between the frequency of the first (SF) and second (M4) series of pulses.  Finally, a circuit is provided which combines the three series of pulses into a drive signal (M3).   The drive signal length is determined by the frequency of the first series of pulses (SF).  The drive signal further is divided into two sections, an initial pulse stage determined by the frequency of the third series of pulses (M3A), and modulated pulses stage being a series of pulses determined by the frequency of the second series of pulses (M6).

Abstract: A method and apparatus for identifying a moving web in a paper making machine is disclosed. The method consists of the steps of illuminating the web with the light from a transmitter, reflecting the transmitted light off the web, receiving the reflected light with a light transducer to produce an electrical signal corresponding to the intensity of the received light, and identifying the moving web based on the received signal. The intensity of the transmitted light is adjusted so that the received light signal from the transducer is normalized with respect to an optimum value. The apparatus consists of a light transmitter, a light receiver, and a control and identification circuit which identifies the web based on a signal from the light receiver, and which adjusts the intensity of the light transmitter to optimize the reception of the signal from the light receiver in order to minimize the effects of environmental interference.

Inventor: WATANABE SHIGEKI
IPC: H04B10/50
Filed: 1991-09-13
Abstract: At a  transmitting end,  transmission signals corresponding to more than one channel are allocated different microwave frequencies and carriers of the microwave frequencies are modulated with the transmission signals in modulators.   A filter is placed in the preceding or succeeding stage of a respective modulator to band-limit a corresponding transmission signal before or after modulation.   The band-limited and modulated transmission signals are combined to produce a microwave frequency-division multiplexed signal.  The multiplexed signal modulates an optical frequency modulator to produce an optical modulated signal. The optical modulated signal is transmitted to the receiving end.   At the receiving end, the optical signal transmitted from the transmitting end is detected and converted to an electrical signal.   The channel components are extracted from the electrical signal by bandpass filters and then demodulated.

Inventor: BORRELL RONALD A
IPC: G01S7/526
Filed: 1993-03-22
Abstract: A system (10) and method (10A) for automating signal tracking, estimation of signal parameters, and extraction of signals from sonar data to detect weaker signals. A maximum a posteriori (MAP) algorithm processing provides a track output of thesignal which is used as a guide or template to provide optimal spectral integration on an unstable or frequency varying line. The present invention includes track integration (15), parameter estimation (17), signal track normalization (16A), and sequential signal detection (18). The present invention partitions (12) the input band into frequency subwindows (31-35). For each subwindow (31-35), the strongest signal is tracked, its parameters are estimated, and then the signal is normalized (removed) (17) from the subwindow. This is repeated until the entire subwindow set is processed. Then the subwindows, now with their strongest signals removed, are recombined to form oneinput band. This aggregated procedure represents one processing pass. In the next pass, the entire above procedure is repeated with either the same or new subwindow boundaries. This continues until a predetermined number of passes is completed. Sequential signal detection is provided from one data frame to the next, a problem that is beyond the capability of conventional systems and methods for tracking frequency lines of unknown frequency modulation and amplitude.
