  • Patent number: 11003765
    Abstract: Disclosed is a computer program that is used for detecting a system abnormality and controlling a causative service in a computing device. In a computer program stored in a computer-readable storage medium, including encoded commands, which causes one or more processors to perform operations for detecting a system abnormality in the computing device when the computer program is executed by the one or more processors of a computer device, the operations may include: an operation of receiving monitoring information for each client from a plurality of clients of the computing device; an operation of comparing each monitoring information for each client with a system monitoring policy; an operation of determining whether the system abnormality occurs based on a comparison result with the system monitoring policy; and an operation of determining to control some clients among the plurality of clients based on the determination of whether the system abnormality occurs.

  • Patent number: 7583039
    Abstract: The present invention discloses a control technology for brushless DC motor, in which firstly it is to build or import a motor running parameters' database, then detect the signals always running and the signals closely relevant to the rotor's rotating state such as the voltage and the current, and process these signals and figure out the signals about the rotor's position. Wherein these detected signals should be filtered before being used, and the best filter is the low-pass filter to cut out the high frequency components, and the cut-off frequency of the low-pass filter are determined by the motor running voltage U and PWM signal width when the motor is running at no load, finally determine if the motor is working properly by means of the motor running parameters stored in the database in advance, that is to determine if the detected value is identical with the one predicted from the database.

  • Patent number: 6092583
    Abstract: A closure member comprises a flexible sheet curved wavily so as to wave in the horizontal direction, and a drive which causes the flexible sheet to wave forward. A closure structure comprises this closure member and is further provided with a wall member on each side of the flexible sheet in the hill-to-valley direction in its side view, which may further be provided with a moving floor beneath the flexible sheet.

  • Patent number: 4224988
    Abstract: A device for and method of sensing conditions in a well bore by positioning a radioactive source adjacent the surface of the well bore for emitting a radioactive signal across the well bore. A means for detecting the radioactive signal is positioned opposite the radioactive source and electrical means are mounted with the detecting means for electrically measuring the intensity and frequency of occurrence of each detected signal. An electrical signal is provided by the electrical means for indicating the presence or absence of drilling fluids and/or the density of such fluids at the surface of the well bore.
