Patent CA-2319864-A1 (CA)
Inventor: VOLLMER JURGEN
IPC: A01B59/041
Filed: 2000-09-15
Abstract: The invention relates to a side strut 5 for a lower steering arm of a tractor. The side strut 5 comprises a single-action hydraulic cylinder and a setting unit with a hollow cylinder 17 and a setting element 20 adjustable therein. The setting element 20 comprises a threaded bore 30 in which there is positioned a threaded rod 32. The hydraulic cylinder is provided with the first attaching means 6 for the purpose of connecting a tractor, and the threaded rod 32 is provided with the second attaching means 7 for the purpose of connecting a lower steering arm. In the fully moved-out position of the hydraulic cylinder, the setting element 20 is rotatable by means of the actuating lever 33, so that, accordingly, the threaded rod 32 moves in and out. To prevent any rotation, there is provided a first holding element 36 which the actuating lever 33 can be made to engage when in the position of rest. There is further provided a second holding element 37 which ensures that, in those cases where the hydraulic cylinder is in a position other than the fully moved-out position, the actuating lever 33 is held in such a way that a rotational movement of the setting element 20 relative to the hollow cylinder - which rotational movement would effect a change in the length setting - cannot take place.

Title: Method, system and media for entering data in a personal computing device
Inventor: DAVIS WILLIAM TRUEMAN
IPC: G06F3/0488
Filed: 2000-10-18
Abstract: In one aspect of the present invention a user can rapidly enter and search for data, such as text, using a data entry system by entering one or more characters on a digital keyboard with a pointing device. With the digital keyboard the user can create words, phrases and other character sequences.    As the user enters a character sequence, a mechanism for keyboard character prediction visually informs the user of which set of characters on the digital keyboard are most likely to have the character that the user wishes to next enter as part of the text. In another aspect of the present invention, as the user forms a character sequence (partial text entry), the character sequence is used to search a dictionary for a set of completion candidates that begin with the character sequence. The data entry system retrieves completion candidates from the dictionary by determining which completion candidates in the dictionary are more likely to be the ones that the user is attempting to type. A rapid navigation system provides for enhanced navigation and retrieval of completion candidates from the dictionary.

Title: Fiberoptic polarizer and method of making the same
Inventor: TAKAHASHI HIROKI
IPC: G02B6/34
Filed: 2001-01-16
Abstract: A fiber-optic polarizer made by a process comprised of providing a substrate, coupling or embedding an optical single mode fiber to the substrate, making a narrow trench across the fiber at an angle, thereby bifurcating the fiber core into a first fiber core end and a second fiber core end, inserting and securing a thin polarizing material of a monolithic, non-laminated structure into the narrow trench, such that a light spot size emitted from a first fiber core is completely encompassed by the polarizing material, and the light spot size emerging from the polarizing material is substantially collected within the mode field diameter of a second fiber core. The narrow trench having a width of about 30-50 µm, and the polarizing material having a thickness of about 15-50 µm. The polarizing material having a monolithic composition.  Moreover, the inventive polarizer has good reliability in terms of mechanical durability and weathering, since polarizes is fabricated on substrate in which optical path is entirely sealed. This is a process that eliminates the need to use specialized fibers or fibers that are specially treated such as those with thermally expanded cores (TEC). The process is also an alignment-free process that enables easier and faster mass-fabrication. This process produces multiple polarizers at a time.
