Patent CA-2396259-A1 (CA)
Inventor: CUTLER DONALD R
IPC: H05K3/00
Filed: 2001-01-05
Abstract: La présente invention utilise de préférence des capteurs capacitifs sans contact à déplacement réduit (124, 128, 130, 131, 132) pour déterminer des erreurs d'Abbe liées au tangage (20), au lacet (22) ou au roulis (18) d'un étage mécanique quasi linéaire (56, 58), ces paramètres n'étant pas indiqués par un indicateur de position axé, tel qu'un codeur à échelle linéaire ou un interféromètre au laser. Ce système est étalonné par rapport à une norme de référence précise de manière que les corrections dépendent uniquement de petites modifications de détection dans les lectures des capteurs, et non de la précision absolue des lectures de ces capteurs. Malgré le fait que la présente invention soit d'abord destinée à des systèmes de positionnement à axe divisé (50) dotés d'étages à séparation inertielle (56, 58), elle peut être utilisée dans des systèmes à étage empilé ou à axe divisé classiques, d'où une réduction de leur coût de fabrication.
Patent CA-2398560-A1 (CA)
Inventor: NIGHTINGALE CHRIS EARL
IPC: A61M16/06
Filed: 2002-08-19
Abstract: A nasal mask is disclosed which is more comfortable for the user to wear and reduces side leakage as compared to masks of the prior art. In a first form headgear for securing a mask to the user's face is disclosed where a section of at least one strap securing a mask to a user's face is substantially more elastic then the remainder of the strap. Headgear of this type allows the user to tilt the head backwards without lateral movement of the mask. In a further aspect, headgear tensioners are disclsed which provides a preset fitting of the mask and ensures that a user cannot over tighten the straps. The tensioners are recalling tension devices attached to the straps and/or mask on either side of the mask. In another form the headgear tensioner is a strap attachment on either side of the mask that allows the straps to move back through the attachment to a predetermined position that provides an appropriate tension between the back of the user's head and mask. This limits the amount of leakage from the mask when the straps tighten or loosen as the user moves his/her head.

Patent CA-2404927-A1 (CA)
Title: Tensioner
Inventor: DEC ANDRZEJ
IPC: F16F7/08
Filed: 2001-04-12
Abstract: The invention comprises a self-contained mechanical belt tensioner that produces damping which is a function of the applied hubload through the effect of frictional forces derived from the sliding action of mutually opposing wedges. A first wedge or conical piston is contained within a housing. The conical piston cooperates with a second or conical wedge. A surface of the conical wedge slides on the inner surface of the housing. The conical wedge is expandable in a direction normal to the inner surface of the housing. A spring urges the conical wedge into engagement with the conical piston. As the pulley is loaded, as with an impulse load, the piston will move into the conical wedge. This, in turn, will cause the conical wedge to expand against the inner surface of the housing. The expansion of the conical wedge in the housing will increase the frictional force between the conical wedge and the housing. This will have the effect of damping movements of the conical piston and, in turn, of the pulley. The greater the impulse, then the greater the expansion of the conical wedge. This increases the resultant frictional force resisting movement between the conical wedge and the housing. As the load moves toward a minimum, the frictional force is abated to a low level allowing ease of retraction of the piston.

Title: Drive device, in particular for the closing unit, the injection unit or the ejectors of an injection molding machine for plastics
Inventor: DANTLGRABER JORG
IPC: B29C45/40
Filed: 2001-04-28
Abstract: A drive device which is used in particular for the closing unit, the injection unit or the ejectors of an injection molding machine for plastics and which has a drive element which can be moved axially by an electric motor, and a hydraulic unit which can be moved in the same direction as the drive element by moving the latter. In drive devices for the applications, it is important to first of all perform a rapid regulating movement and then exert high forces. In a known drive device having these features, the hydraulic unit is a hydraulic cylinder which is adjusted by the electric motor via a stroke spindle during the regulating movement and to which pressure medium is fed via a valve for exerting a high force. In this known drive device, in addition to the electrical installation, a complete hydraulic system is also necessary. In addition, high reaction forces act on the stroke spindle. This is avoided wherein the hydraulic unit is a power transmission means having two pistons, which are movable relative to one another and differ from one another in the size of their effective areas, and having an intermediate part which together with the pistons encloses a pressure space filled with a pressure fluid, if the small piston having the smaller effective area is mechanically connected to the drive element, if the hydraulic unit can be moved as an entity for the regulating movement, and if, for exerting a high force by the large piston having the larger effective area, the intermediate part can be locked against displacement relative to a fixed frame.

IPC: H04N1/407
Filed: 2002-03-28
Abstract: In gray-scale correction where extension to a dynamic range is performed based on a maximum value and a minimum value of a video luminance signal, sufficient correction effects cannot be obtained in some displayed images. Therefore, a histogram detecting circuit (2), a maximum value detecting circuit (3), and a minimum value detecting circuit (4) respectively detects, for each field, a maximum value (Kmax) and a minimum value (Kmin) in a detection WINDOW set in a screen, and distribution information in a gray-scale direction. The detected maximum value (Kmax) and minimum value (Kmin) are respectively corrected by a maximum value correcting circuit (5) and a minimum value correcting circuit (6) based on the output results of the histogram detecting circuit (2), and output as a corrected maximum value (Lmax) and a corrected minimum value (Lmin). Based on these corrected maximum value (Lmax) and a corrected minimum value (Lmin), an input video luminance signal is corrected. Thus, it is possible to obtain optimal effects of gray-scale correction in accordance with a scene.
