PCT No. PCT/JP94/00765 Sec. 371 Date Jan. 19, 1995 Sec. 102(e) Date Jan. 19, 1995 PCT Filed May 12, 1994 PCT Pub. No. WO94/27200 PCT Pub. Date Nov. 24, 1994. A robotic arm is driven by a servomotor which is controlled through position and speed control loops. The position and speed control loops are adaptable in response to a flexible position control. Upon receipt of a flexible control command, a position gain and a proportional gain of the speed control loop are lowered in accordance with a set degree of flexibility. The output of an integrator of the speed control loop is also limited to a set clamp value. As a result, a torque command for controlling the servomotor never achieves an expressly large value even if a position deviation increases. In case an obstacle is placed in the transfer path of the robotic arm, the arm can be moved by human power to avoid the obstacle.
5581457 CONTROL DEVICE FOR SEWING MACHINE AND CONTROL METHOD THEREFOR Tsukahara Hisaak Tokyo, JAPAN assigned to Mitsubishi Denki Kabushiki Kaisha A control device for use in a sewing machine and a control method in which the memory contents of a memory element are read when a servo microcomputer generates an interrupt. The control device also changes sewing data by specifying a rewriting format when sewing data are changed, automatically detects the rewriting of the memory contents of a rewritable memory element due to noise, and restores the memory contents to their original state before they have actually been rewritten.
handling network which is ideally disposed for the management of inventory data among a number of dispersed locations, such as a hotel chain. A central computer-processor/data-base is interconnected with a plurality of remote locations, via a novel gateway interface and communications network, which remote locations may comprise either local processors and associated local data bases or terminal devices connected with the system via third-party systems or public networks. Embodied as a hotel reservation and data management network, the system supports not only the storage and exchange of basic room-inventory/reservation data between and among the central and remote locations, but also such advanced data management features as a single depleting inventory for both the central and remote databases, rate plan restricted access, and display of room layout data at an operator’s terminal.
5581467 DISPLACEMENT CORRECTING DEVICE AND METHOD FOR A MACHINE TOOL Yasuda Shot&i Nagoya, JAPAN assigned to Brother Kogyo Kabushiki Kaisha The ratio of executed to skipped measurement movement commands required for actual measurement and a correction value when skipping a measurement movement command are determined and then updated according to past (hysteresis) measurement data. The actual thermal displacement measurement during an executed measurement movement command is performed at a proper rate to improve the machining efficiency of an NC machine tool and minimize an error due to the correction.

MODULAR ARCHITECTURE FOR ROBOTICS AND TELEOPERATION Anderson Robert J Albuquerque,
NM, UNITED
STATES
Systems and methods for modularization and discretization of real-time robot, telerobot and teleoperation systems using passive, network based control laws. Modules consist of network one-ports and two-ports. Wave variables and position information are passed between modules. The behavior of uncoupled into decomposed module is each linear-time-invariant, and coupled, nonlinear memoryless elements and then are separately discretized.
