Patent CA-2162200-A1 (CA)
Title: Efficiently providing multiple grades of service with protection against overloads in shared resources
Inventor: CHOUDHURY GAGAN LAL
IPC: H04Q3/66
Filed: 1995-11-06
Abstract: Techniques for (a) controlling admission of customers to a shared resource, (b) adjusting the capacity of a resource in light of new customer demand, and (c) diverting usage from a failed resource to alternative resources, each use a "blocking probability computer" (BPC) to solve a resource-sharing model that has a product-form steady-state distribution.  The techniques allow each customer to obtain an appropriate grade of service and protection against overloads from other customers. Each customer is a source of a series of requests, and is assigned "upper-limit" (UL) and "guaranteed-minimum" (GM) "bounds" on its requests. The upper limit bound puts an upper limit on the number of requests from that customer that can be in service at any time. The guaranteed-minimum bound guarantees thatthere will always be available resource units in the resources to serve a specified number of requests from that customer.  The desired blocking probabilities are directly expressed in terms of normalization constants appearing in the product-form steady-state distribution. The BPC computes the normalization constants by firstconstructing the generating function (or z-transform) of the normalizing constant and then numerically inverting the generating function.
Patent CA-2162675-A1 (CA)
Title: Endoscope
Inventor: KELLEHER BRIAN S
IPC: A61B1/012
Filed: 1994-06-08
Abstract: An endoscope for insertion into a patient's inner body cavity has a shell with apertures illuminating a lens and passing light from an imaging (or objective) lens, each lens being disposed on the distal face of the shell. The shell also has an aperture, preferably off-round, for receiving a resilient disposable core. The resilient core has passageways for introducing a pressurized fluid (e.g. air or water) to selective ones of the lenses to clean the lenses. The core may also have another passageway for removing material from the patient's inner body cavity for analysis. This passageway may communicate with two conduits for removing specimens from the body cavity as by a vacuum or as by an instrument. The second conduit may be closed except when the instrument is to be inserted into the patient's inner body cavity. The core may be drawn through the shell aperture to position the core in the aperture. A cleaning member may be attached to the core to clean the shell aperture as the core is drawn through the aperture. Alternatively, a leader applied to the core may be drawn with the core through the shell aperture and then removed from the core. Sealing members attached to the core may also be drawn through the aperture with the core to seal the core. Alternatively, members may be sealed to the core or shell after the sealing operation. A cover on a core may alternatively be removed after the core has been drawn through the shell aperture.

Patent CA-2169508-A1 (CA)
Inventor: HORI SEIJI
IPC: B60R22/48
Filed: 1996-02-14
Abstract: A gear mechanism for reducing a rotational speed of a driving gear and transferring the reduced rotational speed to a gear to be driven comprises an arbitrary number of gear teeth attached to the driving gear and smaller than the number of teeth determined by a module and a stopper having a stopper surface which is attached to the driving gear so as to be displaced relative to said gear teeth along the axial direction of the driving gear and which draws a circle identical in size to a circle drawn by a locus of rotation of an addendum of each gear tooth upon rotation of the driving gear and meshes with gear teeth of the driven gear upon disengagement of the gear teeth from the teeth of the driven gear so that the rotation of the driven gear is controlled by the stopper.  Thus, when the gear teeth are in disengagement with the teeth of the driven gear, the stopper is maintained in meshing engagement with the gear teeth of the driven gear so as to prevent the driven gear from rotating.
