Patent CA-2353663-A1 (CA)
Title: Recreational balancing apparatus
Inventor: SACHS MATTHEW E
IPC: A63B69/00
Filed: 2001-07-23
Abstract: A recreational balancing apparatus comprises a frame defining a horizontal opening therein, and a balancing board mounted on a joint assembly in a manner which allows the balancing board to tilt in every direction, and be capable of 360° rotation. The apparatus further comprises an upstanding support post, the post being secured to a lower portion of the joint assembly, and a lower portion of the support post passes downwardly through the frame opening. Support legs are secured to the frame, and a collar, having an opening therein, is provided. A first set of high tension springs connects the collar to the frame, the springs each being connected to a periphery of the collar and an inside portion of the frame, so that the collar is supported centrally within the horizontal frame opening, to provide a stable center for the support post to slide through, and achieve limited tiltable movement in a radial axis about a center of rotation positioned in the center of the collar. A second set of high tension springs or high elastic shock modulus cords each has a first end mounted to a side of the frame and a second end attached to a bottom portion of the support post, whereby the second set of high tension springs supports the bottom of the post and permits limited movement thereon, in a vertical direction.

Patent CA-2358770-A1 (CA)
Title: Thin autotensioner
Inventor: AYUKAWA KAZUMASA
IPC: F16H7/12
Filed: 2001-10-11
Abstract: An autotensioner comprises a torsion coil spring interposed between a base and a rocking arm, and a tubular bushing provided between an inside surface of the base and an outside surface of the rocking arm. The torsion coil spring pushes and biases the rocking arm toward the bushing, and brings the pushing direction substantially in coincidence with the axial load direction of the force, acting on a stepped bolt supporting the rocking arm, from a belt. When the belt tension becomes high, the arm axial center displaces slightly from the base axial center, an extremely large first damping force acts on the rocking arm. When the belt tension becomes low, the smaller second damping force acts on the rocking arm.

Patent CA-2383264-A1 (CA)
Inventor: LIZARDI PAUL M
IPC: C12Q1/68
Filed: 2000-08-11
Abstract: Disclosed is a method for the comprehensive analysis of nucleic acid samples and a detector composition for use in the method. The method, referred to as Binary Encoded Sequence Tags (BEST), involves generation of a set of nucleic acid fragments; adding an adaptor to the ends containing recognition site for cleavage at a site offset from the recognition site; cleaving the fragment to generate fragments having a plurality of sticky ends; indexing of the fragments into sets based on the sequence of sticky ends. The fragments are indexed by adding an offset adaptor to newly generated ends. A different adaptor will be coupled to each different sticky end. The resulting fragments - which will have defined ends, be of equal lengths (in preferred embodiment), and a central sequence derived from the source nucleic acid molecule - are binary sequence tags. The binary sequence tags can be used and further analyzed in numerous ways. For example, the binary sequence tags can be captured by hybridization and coupling, preferably by ligation, to a probe. The probe is preferably immobilized in an array or on sortable beads. One form of the BEST method, referred to as modification assisted analysis of binary sequence tags (MAABST), assesses modification of sequences in nucleic acid molecules by detecting differential cleavage based on the presence or absence of modification in the molecules.

Title: Protective garments with floating armor system
Inventor: VAN DER SLEESEN MICHAEL F
IPC: A41D27/28
Filed: 2000-09-08
Abstract: A protective garment for use when riding motorcycles or other vehicles in which the rider is exposed includes protective armor in, for example, portions of the garment covering the back, shoulders (22), elbows (22) and knees. The armor is attached elastically (24) to the interior of the garment so that it can move freely with the rider instead of being immovably fixed to garment.  The armor thus protects the rider's most vulnerable areas from abrasion or impact, regardless of the rider's movements in the garment, and does not restrict the rider's movements or compromise his comfort while in the garment.
