Title: Electro-hydraulically controlled tractor
Inventor: MOORE NORMAN BRUCE
IPC: E21B23/00
Filed: 1999-12-17
Abstract: A tractor (20) for moving within a borehole comprises body and two propulsion assemblies (24, 26) that are longitudinally movably engaged with the body. The tractor body has annular pistons (34, 36, 38, 40) configured to receive hydraulic thrust to propel the body longitudinally. Each propulsion assembly includes a gripper (42, 52) and propulsion cylinders (44, 46, 48, 50). The gripper has an actuated position in which the gripper limits relative movement between the gripper and the inner surface of the borehole, and a retracted position in which the gripper permits free relative movement between the gripper and the inner surface of a borehole. Each propulsion cylinder contains one of the pistons. The tractor includes a control assembly (30) having valves and hydraulic circuitry which control the sequencing of fluid distribution to the propulsion cylinders, and of the actuation and retraction of the grippers. A throttle valve (54) controls the fluid flowrate to the pistons.

Inventor: LIPKA DIETMAR
IPC: H03H17/06
Filed: 1999-07-15
Abstract: Digital filtering is performed by receiving an L-bit block of 1-bit data samples, wherein L is greater than 1, and using the L-bit block of 1-bit dat a samples to select a corresponding one of 2L filter ouptut values. Selection may be accomplished by using each of the L 1-bit data samples to determine a  product value by alternatively selecting a corresponding filter coefficient or a negation of the filter coefficient, and then generating the corresponding one of the 2L filter output values by adding together the L product values. Alternatively, part or all of the L-bit block of 1-bit data samples may be used to address one or more memory structures having stored therein corresponding filter output values. When more than one memory structure is used, the outputs from the memories are added together to generate the filte r result. In another aspect, a shift register and latch arrangement decimate t he serially received 1-bit data samples, thereby allowing the filter result to be generated at the decimated rate.
