Abstract: ABSTRACT         This invention relates to automotive sound systems, and particularly to a system which employs psychoacoustic contouring of the program material signal, based upon the hearing char-acteristics of the human ear.  The invention is used in a sound system comprising a source of program material, a first transducer, and circuitry for coupling the first transducer to the source to produce an audible signal related to the program material.  The improvement of the invention comprises a variable bass contour control network, a power amplifier, a second transducer and a control circuit.  The variable bass contour control network is coupled to the program material source and the power amplifier.          The second transducer and the control circuit are coupled to the power amplifier.  The control circuit is coupled to the variable bass contour control network, the control circuit controlling the contour of the signal supplied from the program material source through the variable bass contour control network to the power amplifier based upon the signal provided by the power amplifier to the control circuit.

Title: Cascaded internal impedance dependent amplifier with accurate variable gain control
Inventor: YANG STEVE S
IPC: H03F1/30
Filed: 1986-09-18
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE      An internal impedance dependent amplifier has a gain as determined by the impedance at a predetermined node within the amplifier.  A PIN diode is coupled to the predetermined node.  The PIN diode is driven with a forward biased current which serves as the accurate gain control (AGC) signal for the amplifer.  In the preferred embodiment, the PIN diode is driven by an operational amplifier in such a manner that the impedance thus coupled to the predetemrined node in the amplifier is temperature independent.  Becuase the PIN diode has an impedance given by:   log R = A + B log Ip, where R is the impedance of the PIN diode; Ip is the forward biasing current; and A and B constants which are different for each PIN diode, the AGC voltage applied to the operational amplifier driving the PIN diode is linear with respect to the impedance of the PIN diode and hence the voltage gain of the impedance controlled amplifier to which the PIN diode is coupled.  This characteristic of the gain of the amplifier allows the amplifier to be cascaded in series and to preserve the same impedance relation as expressed above for the cascaded series of amplifiers as well.  Thus, the gain in dB of the cascaded series of amplifiers is log linear with respect to a common AGC voltage applied to each of the amplifiers of the series.

Granted: 1991-05-07
Abstract: ABSTRACT     The   invention   relates   a real time,  multiuser, time-share   computer   systems   particularly  adapted  for running  computer  software  written for individual personal computers,  including software that requires the interactive exchange  of  high resolution computer graphics information. Data  is  transferred  between  the host computer and remote terminals  over  a  very high speed serial data transmission line  at a rate of, for example, 25 MHz.  Fiber optic duplex cables  connect  a  host  controller with one or more remote terminals.   One fiber optic cable carries the data from the host  controller  to the remote terminal and the other cable carries   data   from   the  remote  terminal  to  the  host controller.    Specially  dedicated,  high  speed, hardwired electronic  logic,  such  as 74F series TTL hardwired logic, encodes  the  software  commands,  transfers the data over a serial data link, and decodes the data so that slower speed hardware  may  direct  the data to the appropriate operating hardware.    The  data  link can connect terminals in a real time,  time-share  network  that  enables remote stations to share  hardware  and  software  written for the single user, single  tasking  generation  of  personal  computer  without modification  to  the  software,  including  software having high resolution, interactive graphics.

Abstract: TITLE LINEAR BARRIER FOR SEPTIC TANKS                                 INVENTOR Alan G. HINES          APPLICANT 638755 ONTARIO INC.                                 ABSTRACT   Concrete septic tanks have inflow and outflow orifices and near the outflow orifice have screening means or baffles which are stapled or bolted to the concrete inner wall so as to force the outflowing liquids to pass a predetermined flow path with the hope to avoid solids passing out of the tank and into a draining tile bed. A novel baffle structure and means for attaching the baffles is disclosed using a linear race with foreward and rearward recesses and flexible marginal flap that seals the race onto a core surface of a mold use to fabricate the tank. After the concrete is poured into the mold and partially cured the core is then removed, and the track remains embedded in the concrete and acts as a holding, sealing and anchoring means for a baffle, preferably made of a non-corrosive material such as a plastic. The baffle is slipped into the race of the track and seepage across the baffle interface with the tank walls is avoided and the predetermined flow path for the outflowing fluids is ensured. In order to inhibit the outflow of Hydrogen and Hydrogen Dioxide gases, an inclined plate can be placed beneath the outflow channel to deflect entrained gases from flowing up into the outflow channel and outflow orifice and into the draining tile bed.
