Patent CA-2520509-A1 (CA)
Title: Platen
Inventor: GLAESENER PIERRE
IPC: B29C45/17
Filed: 2004-03-10
Abstract: A platen (50) for a molding machine includes an intermediate support structure (20) between two planar walls (16, 18) having ribs (40) arranged at a non-normal angle b to a first wall (18). The ribs (40) couple forces from the first wall (18) to the second wall (16) in such a way that bending of the second wall (16) is resisted. This adds to the rigidity of the second wall (16) and hence the platen (50), adding to flatness of the arrangement. Gussets (42) may be provided extending between the ribs (40) and the intermediate support structure (20). This has the effect of surrounding and supporting an injection bore (14) and further adding to the coupling of forces to the edge portions of the second wall (16) to resist forces acting to bend the wall.

Title: Fluidization of particles for encapsulation in oral dosage pharmaceutical products
Inventor: SHOJAEI AMIR H
IPC: A61J3/07
Filed: 2004-05-12
Abstract: Encapsulated oral dosage pharmaceutical products are produced utilizing a system (1) including a hopper (2) and a dosator (10), where the hopper (2) receives particles having irregular geometries and sizes greater than about 100 ~m for delivery to the dosator (10). A gaseous fluid is directed into the hopper (2) to fluidize particles within the hopper (2) so as to minimize or eliminate the formation of voids within the bed of particles disposed within the hopper (2). The fluidization of the particles within the hopper (2) maintains a substantially continuous and uniform flow of particles from the hopper (2) to the dosator (10), which results in the formation of encapsulated products with desirable weights and particle size distributions.

Title: Aqua alert
Inventor: DELOREY DARREN G
IPC: G08B21/08
Filed: 2005-10-06
Abstract: A drowning alarm and position marking system is described herein. The Aqua Alert is a system for detecting the drowning of an individual and subsequent generation of an alarm to alert a parent, lifeguard or by-standers. The system consists of two different units, a portable unit worn by the swimmer and a base station which is worn by a parent/supervisor or located on the beach, pool or boat. The buoyant portable unit transmits a signal which may be ultra-sonic, sub-sonic, audio or optic, but preferably radio frequency in nature. This signal is transmitted semi continuously until the portable unit is submerged in water in which case the signal is cut off from the base station due to the attenuating effects of being submerged in water. The base station will generate an alarm such as a siren or visual means or both if the signal from the portable unit is not received for a period of approximately 10 seconds, thus operating in a fail-safe condition. The portable unit has an on board means of sensing submersion in water and after being submerged for approximately 10 seconds will release a stored line which will allow the unit to remain attached to the drowning individual but float to the surface where both a highly reflective coating and a super high intensity LED will indicate the position of the drowning individual. Additionally, the base station shall incorporate a directional antenna and a related LED display to indicate the immediate direction of the floating portable unit. The transmitted signal from the portable unit may also be manually disabled by the swimmer resulting in the activation of the onboard marking system as well as the activation of the base station alarm. The system may also act as a proximity monitor as the base station will alarm if the swimmer's distance exceeds the transmitting range of the portable unit, which is approximately 200 feet.

Title: A uniform power save method for 802.11e stations
Inventor: BILSTAD MARK
IPC: H04L12/28
Filed: 2004-06-18
Abstract: A power-save QSTA notifies an Access Point (AP) that its operating in a automatic power-save delivery (APSD) mode and negotiates a periodic wakeup schedule and a scheduled startup time with the AP. Wakeup times are synchronized with the 802.11 Timer Synchronization Function (TSF). The AP  automatically sends frames to the QSTA when it determines the QSTA is in an awake state, otherwise downlink frames are buffered. The AP uses a combination poll+EDCF access method wherein at the start of each wakeup period the AP  sends a poll to the QSTA, the poll having a flag that indicates to the QSTA if the AP has a downlink fame buffered for the QSTA. In addition, a Proxy ARP  Server in an AP maintains IP/MAC bindings for associated clients so that when the AP receives a proxy ARP request for a client, the AP may respond for the client.

Title: Dishwasher drain pump assembly
Inventor: WELCH RODNEY M
IPC: A47L15/42
Filed: 2006-01-10
Abstract: A dishwasher includes a drain pump assembly having a chopper assembly coupled to an impeller and driven by a synchronous motor. The chopper assembly includes an impeller housing that includes a central hub portion for pivotally supporting a plurality of rotatable chopper blades. An apertured plate is secured to the impeller housing and maintained in a spaced relationship from the chopper blades. The chopper assembly is coupled to the impeller through an axially sliding drive mechanism that facilitates assembly of the chopper assembly into the impeller housing. The synchronous motor drives the chopper blade in a first direction until encountering a hard soil particle whereupon the chopper blades can pivot so that the chopper assembly can continue to operate or, if the chopper blade becomes jammed, the synchronous motor can oscillate to hammer the hard soil particle until it becomes small enough to pass through the apertured plate.

Title: Optimisation of sequential combinatorial processes
Inventor: RUNNEMALM KARL HENRIK
IPC: G16B35/10
Filed: 2004-09-10
Abstract: A method of optimising a sequential combinatorial process comprising an interchangeable sequence of events comprises using a master model to model a selection of the possible sequences, and using information derived from the master model in a surrogate model that approximates the master model with a much shorter computation time. The surrogate model calculates all the possible sequences using an algorithm to select from the information calculated by the master model that which most closely matches the events of a present sequence, following a prioritised system so that the best match is used wherever possible. All results from the surrogate model are compared so that the modelled sequence that gives the result closest to a desired optimum result for the process can be identified, and potentially applied to the process.  Accuracy can be enhanced by running the optimum sequence through the master model as a check, and further by adding the optimum sequence to the information used by the surrogate model in future calculations. Any sequential combinatorial process, in which the quality of the end result of the process depends on the order in which events in the process are performed, can be optimised in this way, including manufacturing process such as machining, cutting, shaping, forming and/or heat treating a workpiece, flow of material through a factory or oil or gas through a pipeline network, chemical and material science mixing processes, computational biology modelling, and fleet management.
