Patent CA-2405221-A1 (CA)
Inventor: SMITH GLEN DAVID
IPC: G09F27/00
Filed: 2001-04-05
Abstract: An interactive direct response system combines the use of short text message systems (SMS) via cell phones (100) with a database (102) and website to enable advertisers to view in real time customer responses to a direct response campaign. Customers are invited to respond to a defined advertisement on for example a billboard by responding to a single telephone number associated with the website by sending a text message linked to that particular advertisement, i.e. a single word (104,106). A computer receives and analyses the responses and sends an acknowledgement message to the customer.

IPC: G08B25/10
Filed: 2001-04-19
Abstract: A tracking and response system (20, 120), for tracking and monitoring items in a facility environment (22, 122). An identification device (60) embodied wit h a transmitter (90) is assigned to each item. The environment is divided into  domains (100, 101) and zones (102-105) that correspond to discrete and sectional areas of a facility and separated by physical portals (106-110). Receivers (142-146) placed at each portal capture a unique identification number emitted by a passing identification device, and send this number to a  node computer (129-132). The node computer determines the new location of th e item and transfers it to a controller computer (126, 127). The controller computer records the new location and compares it against predefined constraints maintained in a record for the item. Controller computers are connected to a central computer (24, 124) that links the system with independent communication systems (80).

Inventor: BRENNER TOD H
IPC: A61C1/05
Filed: 1997-09-09
Abstract: Air driven dental handpiece motors include a tubular housing and a rotor rotatably supported within the housing. One motor is geared down by the provision of a plurality of idler gears rotatably supported on a hub which rotates between a sun gear on the output end of the rotor and a ring gear fixed within the housing. A drive shaft connects an exposed drive gear with the hub. A bearing is provided between the drive shaft and the inner bore of skirt extending from the ring gear to reduce a number of tolerances built up between the drive shaft and the bearing.      The motor further includes a valve member rotatable through about 140° of arc to vary maximum motor speed and motor rotation direction. The valve member abuts a valve plate having a circular air inlet opening and a semicircular air outlet or exhaust opening. The valve member has an air supply opening which is an elongated arcuate slot having radiused circumferential ends. Shallow, curvilinear recesses are provided in line with circumferential outer and inner walls of the central slot at each circumferential end of the slot and provide fine, low speed adjustment capability to the valve. Deeper recesses at the center of the slot provide an effective air supply orifice diameter at least as great as the effective orifice diameter of the valve plate inlet air opening to maximize top motor speed.

IPC: A62C3/06

Abstract: Air from an air source A, which may be the bleed air of an aircraft, enters the system under the control of an air flow control unit (10). An organic fuel from a fuel reservoir (12 or 13) enters a mixing chamber (16) under the control of fuel flow control unit (14) for mixture with the air. At a first stage the organic fuel is a oxygenated organic fuel from reservoir (12), and at a subsequent stage the organic fuel is a hydrocarbon fuel from reservoir (13). The air and fuel mixture passes to a catalyst bed (18) containing a noble metal catalyst such as platinum, palladium or a mixture thereof. A  relatively low temperature, non-flaming reaction occurs and the resultant gas mixture contains a low concentration of oxygen and larger qualities of inert gases such as nitrogen, carbon dioxide and water vapour. This post reaction mixture, which leaves the system at B, is suitable for suppressing and extinguishing fires, and is especially suitable for purging of air from cargo compartments on board aircraft during a flight on detection of a fire. A  temperature control unit (20) associated with the catalyst bed (18) may be used to prevent its overheating during the reaction. A control unit (24) operates to control the air flow control unit (10), the fuel flow control unit (14) and the temperature control unit (20) in response to signals from sensing units (22) at various points in the system which detect various parameters such as the gas, pressure, temperature and flow.

Abstract: Hatchlings are raised initially on a strip of sheet material which is laid on the floor of a containment pen with a layer of a feed material for the hatchlings. After the hatchlings have grown to a stage where they can move from the paper, the strip is removed by a hand cart operable by a user walking with the cart, the hand cart having wheels arranged for hand steering movement of the vehicle by the user to follow the strip while avoiding the hatchlings. A support is provided on the vehicle for winding the strip into a roll as the cart is moved across the floor. The support is rotated either by a motor or by a hand prank controlled by the user so that the cart is propelled solely by the winding of the strip onto the troll providing a pulling action on the cart and by pushing by the user.
