Title: Adjustable snowmobile seat
Inventor: VAISANEN ESA
IPC: B60N2/24
Filed: 2005-10-20
Abstract: An adjustable seat for a snowmobile has a base having an upper sitting portion for accommodating a driver and a slidable coupling for sliding the seat relative to a chassis of the snowmobile. The seat is movable between a forward position and a rearward position. Threaded fasteners or other connectors are employed to secure the adjustable seat to the chassis in an ergonomic position. The adjustable seat thus accommodates drivers of different height and/or drivers who adopt different postures when riding by comfortably seating the driver on the sweet spot of the seat regardless of the driver's height or his driving posture.

Abstract: A improvement to video compression techniques is described in which blocks o f video input information are compared in their respective pixel values to corresponding blocks of immediately preceding frames. The blocks are analyze d to determine whether change has occurred in accordance with two tests. First , the pixel values of the block are compared to the pixel values of a precedin g block and if a threshold number of pixel values in the block exceed their counterparts by a threshold amount, then the block is assumed to have change d and is communicated via a standard communication protocol, compression technique and media. Second, even if the threshold number of pixels in the block has not changed, the pixel values are compared with their prior frame counterparts to determine if any one pixel value has changed in magnitude mo re than a second threshold amount. Again, one such pixel is identified, then th e block is assumed to have changed and is communicated.

Title: Preload library for transparent file transformation
Inventor: VO KIEM-PHONG
IPC: G06F17/30
Filed: 2004-06-08
Abstract: A preload library partitions certain files into segments and transforms the data of the files on a segment by segment basis (22a), each independently of the other. The transformed segments are then stored as part of a transformed file, with each segment corresponding to a bag containing a chunk (of transformed data) and a gap which permits the chunks to grow when data of the segment is modified during a write operation. The bags are followed by a chunk map which contains metadata, defining the compressed version of each segment (20a). The preload library intercepts system calls from applications to the OC  specifying access to specific segments of a transformed file. The preload library identifies the chunks corresponding to the specified segments, retrieves and reverses the transform on those chunks and passes the data to the application requesting it. For a system call to write data to certain segments, the data is modified and re-transformed by the library before being written back to disk. A preload library provides improved random access into transformed (e.g. compressed, encrypted, etc.) files.

Inventor: BARTZ KATHLEEN M
IPC: G07C3/04
Filed: 2004-12-16
Abstract: An induction heat treating process with a remote sensor for monitoring the duration of energization of an induction heating coil each time the induction heating coil is consecutively cycled. An identifying tag is preferably attached to, embedded within the induction heating, coil or within, the surrounding area of the induction coil and transmits a signal to a remote counting sensor that .is preferably triggered by and responds to the change in voltage generated as the coil is energized. Alternative means of measuring a cycle may be implemented. The output data from the sensor provides useful information for determining the lifespan of an induction heating coil.  Predicting the lifespan of a coil optimizes production by anticipating failure and. replacement of a coil during a predetermined down time, limiting on-site inventory, and revolutionizing, the billing cycle based on a per cycle cost while decreasing overall production costs and improving inductor coil quality.
