Patent CA-2300566-A1 (CA)
Inventor: WARDZALA ROBERT W
IPC: B61L29/04
Filed: 2000-03-07
Abstract: The output voltage of a D.C. motor used to raise and lower a railroad crossing gate is monitored to detect when the D.C. motor begins to generate power, indicating that the motor is being driven by a rising gate arm. If the motor generates power above a adjustable predetermined value, the gate arm mechanism is considered to be operating too fast whereupon an impedance is shunted across the motor's armature thereby applying a load to the generating motor. The electrical load causes the motor to act as a dynamic brake slowing the gate arm mechanism operation and reducing the likelihood that the mechanical components of the crossing gate arm mechanism will be damaged.

Abstract: The present invention relates to a method for automatic bow adjustment for a venetian blind assembly machine; said bow adjustment station comprising rollers (48; 104, 106) for guiding, bending and levelling a strip material (43; 112), and further comprising a forming section (36; 102) where mating concave and convex upper and lower form rollers (50; 108, 110) are arranged for creating a transverse curvature in the strip material, further comprises the steps of: providing levelling through means for offsetting (34;  100, 102) in order to straighten the bow of the strip material (43; 112) within a predetermined deviation on a predetermined length of strip material; measuring the deviation through optical means (146) providing a deviation signal; and adjusting the levelling by said means for offsetting (34; 100) through the deviation signal, if said measured deviation exceeds a predetermined deviation, in order to keep the deviation within said predetermined deviation. In addition, the present invention also relates to an arrangement for automatic bow adjustment for a venetian blind assembly machine. An advantage over prior art is that the bow adjustment is better controlled, the adjustments can be done with an increasing rapidity and a decreased wastage of strip material is obtained.

Inventor: HICKS SCOTT G
IPC: H04W60/00
Filed: 1998-11-16
Abstract: A mobile station in a wireless communication network registers periodically with the network by sending a registration message to the network on a control channel. After a predetermined consecutive number of registration attempts are made by the mobile station without a registration response from the base station, the mobile station leaves the current control channel and searches for a new control channel on which to acquire service. After acquiring service on the new control channel, the mobile station can register with the network to recover service.

Title: Two-piece external incontinence device
Inventor: KAY DENNIS M
IPC: A61F5/453
Filed: 1999-01-15
Abstract: A two-piece external incontinence device includes a first member, which attaches comfortably and reliably to the urethral meatus of a patient, and a second member. The first member may be secured to the patient's parameatal area by suitable medical grade adhesives.  The second member has a first end, which is dimensioned to be mated with the first member, and a second end, which is dimensioned to be mated with a standard urinary drainage tube or a straight connector or other medical apparatus. Mating of the first member and the second member should be leak-free and reliable, but should insure that, when excessive force is applied by pulling on the standard urinary drainage tube, the first and second members separate to eliminate transference of the force to the patient. These mating pieces also allow intermittent internal catheterization without the loss of the parameatal seal.

Title: Lift dolly for use with stand-mounted tools
Inventor: HEES WILLIAM A
IPC: B60B33/06
Filed: 1999-05-24
Abstract: A lift dolly (10) is provided for lifting and transporting stand-mounted power tools (57) and the like, with little effort. The dolly (10) includes a pair of platforms (12, 18) and a wheel system (30) having at least three castors (30) extending downwardly from the platforms (12, 18). The dolly (10) is designed such that one step onto a latching or locking mechanism (58) by the operator causes the wheel system (30) to be forced downward relative to the stand (57) thereby slightly lifting the power tool and stand (59) off the ground and enabling transport of same via the castors (30).  Another step on the locking or latching mechanism (58) disengages the wheel system (30) and permits gravity to return the stand and tool (57) firmly to the ground for use.

Patent CA-2334668-A1 (CA)
Inventor: HELLBERG RICHARD
IPC: G06F17/14
Filed: 1999-06-04
Abstract: The present invention relates generally to the problem of filtering, decimation or interpolation and frequency conversion in the digital domain, and more particularly to its use in wideband multichannel receiver, channelisation, and transmitter, de-channelisation, structures. The invention combines a stand-alone fast convolution algorithm which is further modified and then combined with additional signal processing. By intelligently splitting the filtering effort between the modified fast convolution algorithm block and an additional signal processing block a synergy is created between the two blocks which provides for decreased costs, reduced delay and a reduction in the size of the Fast Fourier Transforms. The resulting advantages are especially useful in any system handling multiple channels simultaneously, but especially where there exist strict requirements on both delay and on input Fast Fourier Transform size.
Patent CA-2335026-A1 (CA)
Title: Multi-fluorescent hairpin energy transfer oligonucleotides
Inventor: NARDONE GLENN
IPC: C12Q1/6818
Filed: 1999-06-11
Abstract: An oligonucleotide, labeled with a molecular energy transfer trio and containing two sequences capable of hairpin formation, is used in the detection of two targets by irradiation with a single wavelength of light. O ne of the two sequences contains an energy donor and a first energy acceptor, a nd the other sequence contains a second energy acceptor. The donor is in close proximity to the second acceptor only if the hairpin is formed, while the donor is always in close proximity to first acceptor. A sample is assayed, using this oligonucleotide in conjunction with another oligonucleotide which  contains the donor fluorophore and the quencher, arranged as described above , but which lacks the acceptor fluorophore. The present oligonucleotide and th e other oligonucleotide are specific to first and second targets, respectively . If a sample contains the first and second targets, then hairpin formation is  prevented after each oligonucleotide is incorporated into a target amplification product or hybridized to a target. Subsequent irradiation of t he sample with the single wavelength of light which excites the donor fluorophore, but not the acceptor fluorophore, causes two distinctive signal s to be generated. The first signal is emitted by the second fluorophore of th e present oligonucleotide, whilethe second signal is emitted by the first fluorophore of the other oligonucleotide. Thus, the first and second targets  are detected when one observes the first and second signals, respectively.</ SDOAB>
