Title: Method and apparatus for limiting speed of air suspended vehicles
Inventor: GROSS PETER
IPC: B60K31/04
Filed: 2003-07-11
Abstract: A vehicle speed reducing system for limiting the speed of a vehicle is provided. The vehicle speed reducing system includes a detector unit for determining a suspension status and a road speed of a vehicle, and outputting a suspension status signal and a vehicle speed signal. A vehicle control device determines whether the vehicle is driven at a non-standard ride height (i.e., air suspended) and exceeds a predetermined maximum speed limit based on the suspension status signal and the vehicle speed signal, respectively. An engine control device limits the speed of the vehicle to a predetermined minimum speed limit if it is determined that the vehicle is driven at the non-standard ride height and exceeds the predetermined maximum speed limit. Since the air suspended vehicle is limited to a minimum speed limit, damage to the vehicle's components is prevented.

Patent CA-2436308-A1 (CA)
Inventor: HILL JASON P
IPC: B29C48/32
Filed: 2001-12-11
Abstract: A thin wall PTFE tube is formed from an extruded green tube (10). The PTFE  tube includes an inner tubular surface and an opposed outer tubular surface defining a tubular wall of a first thickness. The tubular wall is compressed to uniformly reduce the wall-thickness and circumferentially orient the tube. The PTFE tube is positioned over a first elongate roller (22) with the inner tubular surface being in contact therewith. A second roller (24) is positioned against the outer tubular surface of the PTFE tube. The pair of rollers are counter rotated so as to circumferentially compress the tubular (12) wall between the rollers (22, 24). This results in the uniform reduction in the tubular wall (12) from the first thickness to a lesser second thickness and a circumferential orientation otherwise not occuring in an extruded PTFE paste extrusion.

Title: Dynamic balance board
Inventor: BRYDSON GILLIAN
IPC: A63B22/18
Filed: 2002-04-03
Abstract: A dynamic balance board is described that incorporates a means for providing objective measurements on a user's dynamic balance. The balance board comprises a top board, a rocker base and a plurality of force sensitive transducers strategically positioned on the rocker base. When a user stands on the top board the rocker base permits the oscillation of the top board about an equilibrium position. The force sensitive switches then provide output information regarding the angle of the top board and the rotational movement of the balance board relative to the equilibrium position. By monitoring the output information the dynamic balance board provides an objective measurement of the user's ability to balance on the top board.

Title: Electromechanical switch
Inventor: PORTMANN PAUL
IPC: H01H23/06
Filed: 2001-09-27
Abstract: The switching part (1) of the inventive switch is tightly enclosed by an elastic membrane (5) in at least the area of its free end. Said membrane als o envelopes the contact surfaces (2) which face towards the switching part (1) , at a distance, and is tightly connected to the switch housing (4; 6). This ensures that the contact area is tightly sealed in relation to the environme nt of the switch, which in turn ensures reliable protection against contaminati on and oxidation of the contact surfaces. The number of switch components is reduced, advantageously, an additional mechanical spring for holding the latching position of the switching part (1) being superfluous, and miniature embodiments are therefore also possible.

Inventor: CAPONI RICHARD C
IPC: F16B4/00
Filed: 2004-02-25
Abstract: A helical grooved pin for insertion into a hole in a hard host material includes a formed portion of helical lands and grooves. Pin material from the grooves is displaced to define lands at an expanded diameter relative to the pin stock material. The forming process employs a rolling die configured to produce substantially uniform cylindrical land surfaces. The helical lands have a width that is at least five times the height of the land. The expanded diameter of the formed portion of the pin is no more than 5% larger than the diameter of the pin stock material. These proportions provide a uniform, durable and reliable retaining surface to the pin which is particularly useful in applications where the host material is harder than the pin.
