Patent CA-2141644-A1 (CA)
Inventor: STEWART RICHARD J
IPC: F41B5/22
Filed: 1995-02-01
Abstract: The present invention includes an arrow guide and bow sight adaptable to right-handed or left-handed archery bows. The arrow guide including a vertical support wheel with a V-shaped groove running along its circumference in which an arrow may rest when shooting. This wheel is designed spin freely on a support rod, reducing friction imparted to the arrow shaft, thus increasing the accuracy, speed, and power of the archer's shot . For lateral support, two horizontal wheels are positioned to either side of the vertical support wheel to prevent the arrow from falling off of the vertical support wheel when the bow is jarred or when the bow string is quickly drawn back. Also connected to the arrow guide device is a sighting device comprising a multiplicity of sight pins and a vertical cross-hair. The sight pins are vertically adjustable to be calibrated to assorted ranges, and both the pins and the cross-hair are horizontally adjustable to account for windage.

Patent CA-2165912-A1 (CA)
Title: Write anywhere file-system layout
Inventor: HITZ DAVID
IPC: G06F12/16
Filed: 1995-12-21
Abstract: The present invention provides a method for keeping a file system in a consistent state and for creating read-only copies of a file system. Changes to the file system are tightly controlled. The file system progresses from one consistent state to another. The set of self-consistent blocks on disk that is rooted by the root anode is referred to as a consistency point. To implement consistency points, new data is written to unallocated blocks on disk. A new consistency point occurs when the fsinfo block (2440) is updated by writing a new root anode for the anode file (1210) into it. Thus, as long as the root anode is not updated, the state of the file system represented on disk does not change. The present invention also creates snapshots (Figure 22) that are read-only copies of the file system. A snapshot uses no disk space when it is initially created. It is designed so that many different snap shots can be created for the same file system. Unlike prior art file systems that create a clone by duplicating the entire anode file and all of the indirect blocks, the present invention duplicates only the anode that describes the anode file. A multi-bit free-block map file (1630) is used to prevent data from being overwritten on disk.

IPC: G01C21/34
Filed: 1996-01-19
Abstract: Method and apparatus for determining a route from a source location to a final destination using a vehicle navigation system having a map database.  At least one intermediate destination is determined from the map database, each intermediate destination being at the other end of an intermediate route from the source location.  A cost value is calculated for each intermediate destination.  A best intermediate destination is selected from the at least one intermediate destination, the cost value corresponding to the best intermediate destination being lower than the cost values corresponding to any other intermediate destinations.  The intermediate route corresponding to the best intermediate destination is then communicated to the user of the vehicle navigation system while a remainder route to the final destination is determined.

Title: Means of handling multiple sensors in a glucose monitoring instrument system
Inventor: MOULTON JOSEPH L
IPC: B01L99/00
Filed: 1996-02-28
Abstract: A sensor dispensing instrument (20) includes a sensor magazine (26) that contains a plurality of blood glucose sensors (38) disposed in sensor slots (30A-J).      Each of the sensor slots (30A-J) is in fluid communication with a desiccant cavity (50A-J) in which desiccant material is disposed. The front and rear walls (34, 32) of the sensor magazine (26) are sealed with burst foils (40, 42) so as to seal the sensor slots (30A-J) and the desiccant cavities (36A-J). The sensor instrument (20) has an outer housing (22) with a laterally extending magazine opening (24) adapted to receive the sensor magazine (26). A pivot rod (28) is moved through the magazine (26) and is locked into an operating position. The magazine (26) is rotated on the pivot rod (28) until a detent arm (48) on the instrument housing (22) engages a detent groove (50A-J) on the magazine (26) to position the magazine (26) in a sensor feeding position. Once so positioned, a sensor push rod (54) is pushed forward resulting in the push rod (54) piercing the rear burst foil (42) and engaging a sensor (38) in one of the sensor slots (30A-J) to thereby push the sensor (38) out through the front burst foil (40) and into a testing position. While in this testing position, the sensor (38) can be placed in a blood sample that needs to be analyzed. Once the test is completed, the push rod (54) is advanced forward further to thereby eject the used sensor (38) from the sensor handling instrument (20). The push rod (54) then is retracted to a standby position and the sensor magazine (26) is rotated until the detent arm (48) engages another detent groove (50A-J) so that another sensor slot (30A-J) is in alignment with the push rod (54).

Title: Method of making a laminated product such as a mattress and furniture insulator pad
Inventor: RUCKER JOHN R
IPC: B32B5/18
Filed: 1996-03-04
Abstract: The present invention relates to mattress or furniture insulator pads that are placed between the coil springs and the cushioning material in mattresses or furniture, such as chair seats. Such insulator pads prevent the springs from piercing the furniture cushion and provide a bridge across the springs to more evenly distribute weight over the springs. The insulator pads according to the invention have three layers formed by sandwiching polyurethane foam between stiffening layers, preferably formed from polypropylene openmesh netting. Most preferably, a five layer insulator pad has the polyurethane foam sandwiched between stiffening layers and also has thin outer layers of polyurethane foam, applied adjacent to the stiffening layers, forming the top and bottom surfaces of the pad. Such thin outer layer foam sheets provide friction characteristics that retard relative movement between the cushion and the springs. The invention further relates to a method of making a laminated product, such as an insulator pad comprised of foam and stiffening layers held together with adhesive, in which a thin protective barrier foam sheet is placed between the surface of the compression roller and the sheets to be laminated together. The thin protective barrier foam sheet may or may not form the outer layer of the laminate product and prevents adhesive and foam material from contaminating the surface of the roller.

The base (24) is formed with a toecap (30) at the toe end and a heel counter (32) at the heel end.  Treat (34) projects from the bottom of the base for traction when the boot is not attached to the snowboard.  The highback (26) extends upwardly from the heel counter (32) of the base.  The high back provides aft support to the user.  The upper (28) is fixedly attached to the base and is arranged and  configured to receive the foot and ankle of the user.  The upper has a rearward side adjacent  the  highback. The upper is more flexible than the base and the highback.  A base strap (72) is connected to opposing sides of the base and extends across a portion of the upper.

Title: Plant feeder and method for feeding plant roots
Inventor: KESLER ROBERT H
IPC: A01G29/00
Filed: 1996-03-19
Abstract: A plant feeder having a water reservoir and a water conduit connected to the reservoir at one end.  The other end of the water conduit is adapted to be positioned adjacent the roots of a plant to be fed.  The water conduit has a water permeable plug with water soluble plant food therein whereby water can percolate through the conduit from the reservoir to the roots dissolving plant food on its way, and air and insects are blocked from migrating to the roots.     The method provides placing the other conduit end of the plant feeder of the invention below the roots of a recently transplanted plant, percolating water from the reservoir to the roots through water soluble plant food, and blocking the migration of air and insects to the roots through the conduit.
