Title: Method and apparatus for monitoring an analog meter
Inventor: CHIU MING-YEE
IPC: G06T7/73
Filed: 2001-01-15
Abstract: A method and an apparatus for remote monitoring of analog me-ters employ a Hough Transform on the edge points of the meter scale to obtain the centre of the scale (8, 9, 10). The graduation marks and the needle are detected from the inten-sity profile along various radii (11, 12, 13). Thereby the meter reading can be flexibly adopted to different meter scales during an easy training process. The method can be modified for oblique reading of the scale.

Abstract: A latching mechanism in a vehicle seat hinge assembly having a seatback hinge plate pivotally connected to a seat cushion hinge plate for pivotal movement between a first angular orientation corresponding to a substantially upright position of the seatback member, and a second angular orientation corresponding to a forwardly folded position of the seatback member, comprises a guide disposed in the seat cushion hinge plate and a stop disposed adjacent the guide. A link arm member has an elongate axis and a first end, a second end, and a follower member disposed adjacent the second end so as to be engaged in retained sliding relation by the guide. The link arm member is pivotally mounted adjacent the first end on the seatback hinge plate in spaced relation from the pivot axis for movement about a link pivot axis between a first latchable position corresponding to the first angular orientation and whereat the follower member contacts the stop, and a second latchable position corresponding to the second angular orientation and whereat the follower member contacts the stop, and through an intermediate unlatching position corresponding to an intermediate position between the first and second angular orientations and whereat the follower member is removed from contact with the stop. A latch is mounted on the seat cushion hinge plate for selectively holding the follower member of the link arm member in restrained contact with the stop, to thereby retain the seatback hinge plate in either of the first and second angular orientations.

Title: Method and system for routing packets over parallel links between neighbor nodes
Inventor: YAMADA KENSHIN
IPC: H04L47/41
Filed: 2001-07-31
Abstract: In a communications network formed by routers interconnected by parallel component links, hello packets are exchanged between neighbor routers at intervals to know each other in a learning process and update their status. Each router groups the parallel component links into a bundled link according to a link-up or link-down request and produces a first database mapping the relationships between component links and bundled links. The router performs routing calculations according to a link state routing algorithm using the bundled link as a unit of transmission medium and produces a second database mapping relationships between destination addresses and bundled links. The first and second databases are downloaded to interface units connected to the parallel component links. When a data packet is received, the databases are used for translating the header of the data packet for allowing it to be routed through a switch for transmission.
