Title: Dyes designed for high sensitivity detection of double-stranded dna
Inventor: GLAZER ALEXANDER N
IPC: C12Q1/6816
Filed: 1994-04-28
Abstract: Novel fluorescent dyes are provided, characterized by having a fluorophore joined to a polycationic chain of at least two positive charges. The dyes are found to provide for high enhancement upon binding to nucleic acid and have strong binding affinities to the nucleic acid, as compared to the fluorophore without the polycationic chain. The dyes find use in detection of dsDNA in gel electrophoresis and solution at substantially higher sensitivities using substantially less dye.
Patent CA-2164018-A1 (CA)
Inventor: ANDERSEN STEVEN
IPC: H04B1/18

Abstract: An equalizer employed with a receiver for cancelling an interfering signal due to low cross-polarization isolation. The present equalizer provides a simple and inexpensive cross-polarization interference cancellation system. The equalizer uses an error signal generated in an adaptive baseband equalizer to determine the magnitude of an interfering signal and inputs a cancelling signal to the co-polarized channel until power in the error signal derived from the adaptive baseband equalizer is minimized. In the equalizer, the determination of the magnitude of the interfering signal is performed at baseband (after demodulation but prior to data detection) and the cancellation is performed at RF, prior to dispersive microwave elements. The equalizer enhances the capability for transmitting two unique signals in the same frequency allocation on orthogonal polarizations. The equalizer operates even if the modulations and data rates on the two channels are different. In the receiver, co- and cross-polarized signals are received and amplified. A copy of the cross channel input signal is supplied to each receiver channel. An RF vector modulator is used to control the phase and amplitude of the cross-polarized signal prior to summation with a desired co-polarized signal. When the amplitude and the phase of the vector modulator are correctly set the interfering signal is cancelled. Control for the vector modulator is generated by minimizing the magnitude of the error signal in the adaptive baseband equalizer. The error signal is the difference between the received baseband data and an estimate of the ideal transmitted data. A control logic circuit sets the phase and amplitude for the vector modulator to minimize the magnitude of the error signal by stepping the setting of the vectormodulator by one unit and sampling the power in the error signal. If the power is reduced the vector modulator is stepped again in the same direction. If the power is increased the vector modulator is stepped in the opposite direction.

Abstract: The  method  is  used  to  create  a  virtual  public numbering domain, which will coexist with and be parallel and non-intrusive  to  the  existing  geographic  North  American telephone network numbering plan.   It will have capacity to provide additional and more flexible numbering resources which will stimulate and enable many new service applications.   The existing   telephone   network   infrastructure   has   digital switching points and a database system.   The method consists in receiving at one of the digital switching points a called number, and verifying whether the number called is a number of the virtual public dial plan.   If the number called is  a number of the virtual public dial plan, the next steps consist of forming with the number called a virtual public address of predetermined length, supplying the virtual public address to the database system to determine a corresponding network node address,  and  to supplying  the  corresponding  network  node address to the digital switching point and routing the call through the network infrastructure according to the existing dial plan.   If the number called is a number of the existing dial   plan,   the   call   is   routed   through   the   network infrastructure according to the existing dial plan and the number called.

Title: Compact golf facility and method for eliminating handicap scoring
Inventor: JONES ROBERT TRENT
IPC: A63C19/00
Filed: 1994-07-08
Abstract: A compact golf facility and golf playing method include a driving range (24) and a golf course (19) comprising a plurality of holes that each includes a plurality of teeing areas (1-3), a target green (4), and a plurality of target cups (5) within the target green (4). The various teeing areas (1-3) are positioned at significantly different distances from the target green (4) and various target cups (5) are spaced about the target green (4) to provide multiple teeing areas (1-3) and target cup (5) combinations with associated different trajectories over various terrain to accomodate a wide range of skill levels among players. Players can therefore directly compare their actual scores on each hole, and over the entire course, without adjusting those scores by a handicap figure. The driving range (24) includes two drive teeing areas (25-28) that are displaced at opposite ends of a common target area a sufficient distance apart to assure that a ball driven from one drive/teeing area (25-28) cannot reach the drive/teeing area (25-28) at the opposite end of the target area. This driving range (24) uses half the width of a conventional driving range containing only a single drive/teeing area and only slightly longer length to accomodate a comparable number of players simultaneously.

Inventor: CAMERON RICHARD J
IPC: H01P1/20
Filed: 1996-03-29
Abstract: A microwave filter has a plurality of resonant cavities with each cavity containing a dielectric resonator.  There are self-equalizing probes or self-equalizing apertures located between some of the cavities.  A circulator is connected to an output of the filter.  The circulator has an input/output which is connected to an equalizer.  The equalizer contains a dielectric resonator that is slightly different from the dielectric resonators of the filter to permit the equalizer to be tuned at a slightly different frequency from the filter.  The equalizer and self-equalizing probes or apertures are capable of being operated to reduce a dispersive slope of the filter.  The filter can operate in a single mode or a dual mode.  The electrical performance of the filter is superior to prior art filters, particularly in the wideband versions because the dispersive slope is reduced.
