Patent CA-2576132-A1 (CA)
Title: Pivoting handle and control arrangement for a floor care appliance
Inventor: TONDRA AARON PATRICK
IPC: A47L9/28
Filed: 2004-06-01
Abstract: The invention is a pivoting handle and control arrangement for a floor care appliance such as a vacuum cleaner. An actuator rod in the handle is utilized for remotely triggering a switch located in the lower part of the housing. The switch could be utilized for controlling a feature of the floor care appliance such as a surge control for a vacuum cleaner's suction motor. A trigger positioned on the handle is operatively connected to an actuator rod traversing the interior of the handle. The distal end of the actuator rod is in operative engagement with the switch when the handle is in the upright position. When the trigger is depressed, the actuator rod depresses the switch causing it to close. The feature controlled is thereby energized. When the handle is moved to the folded position, the actuator rod is folded with the handle and moved away from the switch.
Patent CA-2576488-A1 (CA)
Title: Compact shooter localization system and method
Inventor: BARGER JAMES E
IPC: G01S5/22
Filed: 2005-08-11
Abstract: Systems and methods for locating the shooter of supersonic projectiles are described. Muzzle blast signals are neither sought nor required. The system uses at least two sensors, with each sensor having a 3-axis accelerometer. The sensors are spaced apart at least 1 meter and have each a diameter of about one centimeter. The three accelerometer signals of each sensor represent pressure gradients and are processed to find the shockwave arrival angle unit vector, the shockwave arrival time instant and peak pressure. Noise signals seldom cause false detections with this sensing method because the sensors have maximum sensitivity at the high frequency characteristics of shockwaves, while their sensitivity to the low frequency characteristics of ambient noise is relatively low.

IPC: F03D11/04
Filed: 2007-03-15
Abstract: One or more vertical axis wind turbines (VAWT), preferably of the Savonius type, are mounted in a relatively simple and inexpensive manner. For a single VAWT a center pole may be disposed within a hollow shaft of the VAWT  with at least upper and lower bearings acting between the shaft and center pole.  Alternatively, a short tower or platform may mount a lower bearing (e. g.  about 4--14 feet off the ground) for the VAWT shaft, and an upper bearing for the shaft may be mounted by an outrigger. The outrigger is connected at a number of different points (e.g. different arms) by strands (such as steel cables) to stationary supports. Where multiple VAWTs are provided, them may be in a cluster. Each VAWT in the cluster has a structural support in common with at least one other VAWT of the cluster, and each VAWT is operatively connected to a separate useful driven mechanism (such as an electricity or fuel gas generator). Each VAWT typically has an outrigger mounting an upper bearing, with strands, rods, or bars, connecting outriggers of adjacent VAWTs together.    Different VAWTs in the cluster preferably rotate in different directions.

Title: Methods and kits for detecting heparin/platelet factor 4 antibodies
Inventor: MILUNIC DAVID
IPC: G01N33/543
Filed: 2005-10-04
Abstract: Methods for determining the presence of heparin/platelet factor 4 antibodies in a sample suspected to contain heparin/platelet factor 4 antibodies are provided, along with apparatus suitable for performing the methods. The method depends upon a color visualization indicating the presence or absence of heparin/platelet factor 4 antibodies in the sample. Preferred methods comprise contacting the sample with particles being complexed to platelet factor 4 (PF4) and which particle-complexed PF4 reacts specifically with heparin/platelet factor 4 antibodies, passing the sample/particle mixture through a filter, and then analyzing the color of the filtrate. The presence of heparin/platelet factor 4 antibodies in the sample is established where the color of the filtrate is substantially different from the color of the receptor-bearing particles.
