Title: Method for compressing scanned colored and gray-scale documents
Inventor: THIERSCHMANN MICHAEL
IPC: H04N9/64
Filed: 2000-12-01
Abstract: A new method for compressing scanned documents.      Starting with the division of the document into three planes -foreground image, background image and mask image - the basic course of the compression method is as follows: A locally variable threshold value image is generated from the original document using an adaptive threshold method. The original image is then quantized using this threshold value image generating a bitonal quantized image.      A text detection (segmenting) method uses the bitonal quantized image and the original image to divide the document into foreground and background regions, classifying text and graphics as foreground regions and images and text background as background regions. A mask identifying the foreground and background regions is generated by the text detection method. A reduced resolution foreground image, describing the colore of the foreground regions, is produced from the original image and the mask image. A reduced resolution background image, describing the color of the background regions, is produced form the original image and the mask image. The mask image, the background image and the foreground image are finally coded independently using suitable image colors.

Title: Attachment assembly for use on flat roofs
Inventor: PALMER THEODORE R
IPC: E04G21/32
Filed: 2001-02-13
Abstract: An attachment assembly provides a secure attachment point for the fall arrest tether lines of safety harnesses of workers on flat roofs, the assembly being movable over the roof as required. The assembly can be used alone, but usually is mounted on a wheeled utility cart as employed by roofers to move materials on the roof, or may be an integral part of such a cart. The assembly has a base frame that is spaced from the roof edge over which the worker may fall. An attachment member for tether lines is mounted on the base frame together with at least two longitudinally spaced surface engaging arm, the arms being located at the frame side nearer to the roof edge. When the assembly is in operative position each arm has its lower end, which usually has teeth, close to the roof surface. A counterweight is mounted on the opposite side of the base frame. Upon a fall from the roof the tether line pulls on the attachment member downward and toward the edge, the pull tilting the base and cart frames to engage the teeth with the roof surface, whereupon the ends become pivots about which the frames can pivot against the counterweight, which ensures only minor tilting and/or dragging of the assembly toward the edge. With e.g.  concrete roofs the teeth may be replaced by bolts in the surface against which the arm ends butt for the assembly to pivot.

Title: Method and apparatus for determining position in a pipe
Inventor: ZIEROLF JOSEPH A
IPC: E21B47/09
Filed: 2000-04-04
Abstract: A method and apparatus for determining position in a pipe provides for the precise determination of location and associated characteristics of each pipe joint of a well, cross country pipeline or other fluid transmission line. The system includes a passive or active radio identification device at each joint in the pipe or casing string. The devices are preferably sealed within the resilient seal positioned between each pipe or casing joint. A pipeline tool includes a radio transmitter and receiver, with the transmitter transmitting on a frequency selected for resonating the identification devices. The resonant response of each device is detected by a receiver in the pipeline tool, with the response transmitted to the surface via the wireline to which the tool is connected. Alternatively, the tool may include storage information means until the tool can be recovered from the well or pipe. An information storage and retrieval system includes information on the location of each of the identification devices in the well or pipe, e. g., length or depth, pipe or casing diameter, previously logged geological characteristics and stratum at each identification device location, etc.  The system may count each device as the tool passes through the pipe in order to determine the location of the tool at any point. Alternatively, each identification device may provide a distinct signal, with the tool transmitting the signal to the surface (or storing the signal for later retrieval) where the system correlates the signal with previously logged information for that specific location.
