Inventor: LUDSZUWEIT AXEL
IPC: H03L7/197
Filed: 1998-08-10
Abstract: A  circuit  arrangement  for  setting  a  system frequency is specified in which a frequency generator (XO) which supplies a reference frequency is connected to  a  first  phase-locked  loop  (NCO)  having  a  first frequency  divider,  a  first  phase  detector,  a  first voltage-controlled  oscillator  and  a  second  frequency divider,  which is connected between the output of the first oscillator and the phase detector.  In order to set different system frequencies, a second phase-locked loop having a  second phase detector  (PD2),  a  second voltage-controlled  oscillator   (VCO2)   and  a  third frequency divider  (K),  which is connected between the output of the second oscillator  (VCO2)  and the second phase  detector  (PD2),  is  connected  in  between  the frequency  generator  (XO)  and  the  first  phase-locked loop (NCO). In this case, the frequency generator (XO) is connected to the second phase detector  (DP2 [sic]) and the second oscillator  (VCO2)  is connected to the first frequency divider (n). A fourth frequency divider (K)  is  connected by its  input  to the output  of  the first  oscillator  (VCO1),  the  system  frequency  being present at the output of said fourth frequency divider.

IPC: C12Q1/68
Filed: 1997-01-23
Abstract: Methods and compounds, including compositions therefrom, are provided for determining the sequence of nucleic acid molecules. The methods permit the determination of multiple nucleic acid sequences simultaneously. The compounds are used as tags to generate tagged nucleic acid fragments which are complementary to a selected target nucleic acid molecule. Each tag is correlative with a particular nucleotide and, in a preferred embodiment, is detectable by mass spectrometry. Following separation of the tagged fragments by sequential length, the tags are cleaved from the tagged fragments. In a preferred embodiment, the tags are detected by mass spectrometry and the sequence of the nucleic acid molecule is determined therefrom. The individual steps of the methods can be used in automated format, e.g., by the incorporation into systems.

Title: Optical transmission link for wavelength division multiplex transmission, and optical fiber constituting the link
Inventor: MUKASA KAZUNORI
IPC: H04B10/2563
Filed: 1998-09-03
Abstract: The invention is to provide an optical transmission link suitable for a high speed and high bit rate wavelength division multiplex transmission. An optical transmission link 1 is composed of a non-linearity diminishing optical fiber F1, a dispersion adjusted transmission optical fiber F2, and an optical fiber F3 for diminishing and adjusting a dispersion slope. The mode field diameter of the non-linearity diminishing optical fiber F1 is made into 12m or more. The dispersion slope is made small to be nearly zero with the mode field diameter of the dispersion adjusted transmission optical fiber F2 set to 10m or more, and the dispersion produced at the non-linearity diminishing optical fiber F3 is adjusted to be small. At the optical fiber F3 for diminishing and adjusting a dispersion slope, the dispersion slope of the entire optical transmission link 1 is adjusted to nearly zero. The refractive index profile of the fibers F1 and F2 is made into a segment type, and the refractive index profile of the optical fiber F3 for diminishing and adjusting a dispersion slope is made W-shaped. The absolute value of dispersion at any point position in the lengthwise direction of the optical transmission link 1 is made greater than 0.5ps/nm/km, thereby suppressing the generation of four-wavelength mixture.
Patent CA-2247881-A1 (CA)
Inventor: CARAGATA D ARCY WAYNE
IPC: E01C9/10
Filed: 1998-09-23
Abstract: A longitudinally extending channel is embedded in a (typically sloped) driving surface which is subject to snow or ice conditions. The channel is covered with a multiple-aperture grating. The grating apertures are sufficiently small to permit unimpeded passage of vehicle tires over the grating, and sufficiently large to permit the vehicle tires to force snow or ice accumulated above the grating apertures through the apertures and into the channel as the tires pass over the grating, thereby improving traction between the tires and the grating.      Snow or ice forced through the grating into the channel is accumulated within a cavity enclosed by the channel and the grating. The channel preferably extends continuously along substantially the entire length of the driving surface. As snow or ice forced through the grating into the channel melts, the resultant water is removed from the channel by a pump or other suitable drainage means. A pair of parallel grating-covered channels can be embedded in the driving surface, the channels being spaced apart by a distance corresponding to typical transverse vehicle tire spacings.

Title: Method and device for optical coupling
Inventor: DUCK GARY S
IPC: G02B27/28
Filed: 1998-12-22
Abstract: A method and circuit is provided for more efficiently coupling light between two optical waveguides such as optical fibres. When the two waveguides are coupled to spaced apart collimating lenses such as GRIN lenses, the beam propagating between the spaced part lenses may be shifted. In this instance light can more efficiently be coupled out of the output optical fibre if it is angled with respect to the optical axis of the GRIN lens to which it is coupled. This invention provides an output fibre that is nonparallel with the optical axis of the lens it is coupled thereto.

Title: Pressure-responsive lockout valve and method of use
Inventor: WILLARD STEVEN N
IPC: A61F2/26
Filed: 1997-07-28
Abstract: A lockout valve for an inflatable penile prosthesis which responds to internal fluid pressure. The lockout valve comprises a housing having inlet and outlet ports, an interior chamber, an apertured valve seat, and a poppet biased toward the closed position. The inlet communicates with the prosthesis reservoir, and the outlet communicates with the interior chamber and the prosthesis pump. The housing includes a flexible diaphragm which moves toward the poppet when flexed inwardly. Fluid pressure through the inlet port urges the poppet into sealing engagement against the valve seat, therefore closing the lockout valve. Negative fluid pressure applied to the interior chamber from the outlet port (when the pump is actuated) causes the diaphragm to flex inwardly and contact the poppet to open the valve.      The lockout valve operates like a check valve when subject to reverse flow.

Title: Locking device for trailing hitch assembly
Inventor: LAPALME JACQUES
IPC: B60D1/60
Filed: 1999-04-09
Abstract: A locking device for use with a trailing hitch assembly comprising a tow bar with an upstanding ball element and a hitch bar with a downwardly opening socket element sized to fit onto the ball element for coupling a trailer to a towing vehicle. The device has a support plate rigidly connectable vertically and transversely onto the tow bar at a short distance in front of the ball element. It also has an L-shaped locking member comprising a vertical wall and a locking wall projecting perpendicularly from the upper edge of the vertical wall. A first pivot pivotably connects in parallel relationship the vertical wall of the L-shaped locking member to the support plate with the locking wall projecting forwardly towards and above the ball element. This first pivot extends into first holes made in the vertical wall and the support plate close to one of their adjacent side edges at the bottom thereof. The device further has a hooking member comprising a hook-shaped end and an opposite end; a second pivot pivotably connects in parallel relationship the hooking member to the vertical wall of the L-shaped locking member so that it extends just above the upper edge of the support plate. The second pivot extends into second holes made in the opposite end of the hooking member and in the vertical wall on the same side edge as, and above, the first hole. The hooking member is long enough to cause its hook-shaped end to engage and hook onto the upper corner of the support plate that is transversely opposite to the second holes. In use, one can rotate the L-shaped locking member about the first pivot in such a manner as to remove the locking wall from above the ball element and thus to allow uncoupling of the socket element from the ball element, only when the hooking member is previously rotated to disengage its hook-shaped end from the hooking corner.
