Patent number: 12259710Abstract: A machining device for scraping a workpiece is provided. The machining device includes: a drive unit for driving a scraper; a first detection unit for detecting the position of the scraper; a second detection unit for detecting the machining force of the scraper with respect to the workpiece; a first acquisition unit for acquiring information relating to displacement of the scraper; a second acquisition unit for acquiring information relating to the machining force of the scraper; and a control unit for driving the drive unit based on the information relating to the displacement of the scraper by the first acquisition unit and the information relating to the machining force of the scraper acquired by the second acquisition unit, so the displacement and the machining force of the scraper satisfy a prescribed relationship. A control device and a control method for the machining device are also provided.Type: GrantFiled: July 15, 2020Date of Patent: March 25, 2025Assignee: CITIZEN WATCH CO., LTD.Inventors: Yosuke Takahashi, Tadashi Mitsuhashi

Patent number: 8922335Abstract: A weapons container for releasing a defense weapon includes a cabinet, a cabinet door, and an interior securing the defense weapon. Upon detection of a fingerprint input by a biometric sensor, a surveillance camera captures video and an audio intercom provides communication with a central command center. A recording system saves the video and audio to a storage database. A delay release lock secures the defense weapon for an amount of time and releases the defense weapon depending on a signal from the central command center. A communications system is connected over a network to the central command center, a local authority, and an emergency responder. The communications system notifies the local authority or the emergency responder upon detection of the fingerprint input and streams the video and audio to the central command center and at least one of the local authority and the emergency responder over the Internet.Type: GrantFiled: June 4, 2014Date of Patent: December 30, 2014Inventors: Timothy Deweese, Brandon Delibro

Patent number: 8060239Abstract: According to the invention, an initial trajectory (2) that is to be followed in a positionally guided manner is input into a computer (15), said initial trajectory (2) being described by an initial function (AF) such that one respective corresponding position (pA) is determined on the initial trajectory (2) by substituting a scalar trajectory parameter (s) into the initial function (AF). The scalar trajectory parameter (s) is different from time (t) while being characteristic of a distance (s) covered along the initial trajectory (2). The computer (15) filters the initial trajectory (2) with low-pass characteristics referring to the scalar trajectory parameter (s) as a function of the scalar trajectory parameter (s) and thus determines a rough function (GF) such that one respective corresponding position (pG) is determined on the rough trajectory (13) by substituting the scalar trajectory parameter (s) into the rough function (GF).Type: GrantFiled: December 1, 2006Date of Patent: November 15, 2011Assignee: Siemens AktiengesellschaftInventors: Walter Hoffmann, Wolfgang Papiernik, Tomas Sauer

Patent number: 6970750Abstract: An adaptive process controller drives a process variable to be substantially equivalent to a set point and adapts the controller gain, the controller reset, and/or the controller rate, based on model free adaptation. The adaptive controller combines a controller gain computed from an oscillation index with a controller gain computed from a steady state estimate and that adapts the controller reset/rate by forcing the ratio of two of the controller proportional, integral or derivative terms to be equal to a predetermined value.Type: GrantFiled: April 19, 2002Date of Patent: November 29, 2005Assignee: Fisher-Rosemount Systems, Inc.Inventors: Wilhelm K. Wojsznis, Terrence L. Blevins, Dirk Thiele, John A. Gudaz

Patent number: 6810298Abstract: A temperature adjustment apparatus for adjusting a temperature of an object to be temperature-controlled. The apparatus includes a first temperature adjustment mechanism for controlling the temperature of the object to be temperature-controlled, and a second temperature adjustment mechanism for controlling the temperature of the object to be temperature-controlled. The first and second temperature adjustment mechanisms have different temperature control responses, and control the temperature of the object to be temperature-controlled in cooperation with coarse adjustment and fine adjustment on the basis of a difference in response. Also, the first temperature adjustment mechanism and the second temperature adjustment mechanism are operatively connected so that the output of the first temperature adjustment mechanism controls the operation of the second temperature adjustment mechanism.Type: GrantFiled: April 4, 2001Date of Patent: October 26, 2004Assignee: Canon Kabushiki KaishaInventor: Keiji Emoto

Patent number: 6684112Abstract: A Robust Model-Free Adaptive controller is disclosed for effectively controlling simple to complex systems including industrial processes, equipment, facilities, devices, engines, robots, vehicles, and appliances. Without the need of re-designing a controller or re-tuning the controller parameters, the inventive controller is able to provide a wide robust range and keep the system under automatic control during normal and extreme operating conditions when there are significant disturbances or changes in system dynamics. Because of its simplicity and capability, the control system is useful for building flexible and adaptive production systems to fulfill the on demand manufacturing needs of the new e-commerce environment.Type: GrantFiled: April 11, 2001Date of Patent: January 27, 2004Inventor: George Shu-Xing Cheng

Patent number: 6606535Abstract: A machining program is read in and interpreted and a determination is made as to whether the amount of movement called for by a block of commands is larger or smaller than a minimum amount of movement that is established by a feed speed and a one sampling period of a numerical control apparatus. If the amount of movement called for is greater than the minimum amount of movement, feed control is performed in accordance with the current block. If the amount of movement called for by the current block of commands is smaller than the minimum movement amount, an immediate subsequent block of commands is concatenated with the current block, and this concatenation of command blocks is continued until a synthesized block calling for an amount of movement greater than the minimum amount of movement is obtained, this synthesized block then being used to perform feed control.Type: GrantFiled: May 16, 2000Date of Patent: August 12, 2003Assignee: Toshiba Kikai Kabushiki KaishaInventors: Minoru Hamamura, Sadaji Hayama, Jun Fujita, Kazuhiro Shiba

Patent number: 6467155Abstract: A transfer control system for enabling technicians to insert a piston assembly into a cylinder of an engine block. The transfer control system ensures that only one technician at a single time is capable of controlling the insertion of the piston assembly into the cylinder of the engine block. The transfer control system has a proximity sensor and a first control system in communication with the proximity sensor. A second control system is in communication with the first control system.Type: GrantFiled: June 29, 2000Date of Patent: October 22, 2002Assignee: Caterpillar IncInventors: James A. Cook, Brad A. Moore, Kevin R. Shaffer, James L. Thien, Robert L. Walters

Patent number: 6185467Abstract: An adaptive, discrete-time sliding mode controller (SMC) is disclosed which detects and adapts to gain variations in the controlled plant. The overall control effort is generated by combining a linear control effort with a discrete-time sliding mode control effort generated by switching between gains in order to drive the system's phase states toward a sliding line trajectory. A sliding mode variable &sgr;k defines the position of the system phase states relative to the sliding line. The SMC controller is designed such that the sliding mode variable &sgr;k crosses the sliding line and changes sign at every sample interval. For the nominal plant gain, the SMC controller is also designed such that the magnitude of the sliding mode variable &sgr;k+1=−&sgr;k will remain constant (&sgr;k+1=−&sgr;k) and substantially constrained to |&sgr;k|=&Dgr;/(1+&lgr;) where &Dgr; and &lgr; are predetermined design constants.Type: GrantFiled: September 2, 1998Date of Patent: February 6, 2001Assignee: Cirrus Logic, Inc.Inventors: Paul M. Romano, Louis Supino, Christopher T. Settje
