Patent number: 6956491Abstract: Techniques for qualifying and monitoring bearing performance and condition in a rotary servo systems (e.g., galvanometer scanner) are disclosed. A position error signal is analyzed for signal anomalies that can signify bearing damage. A DC offset ramp is applied to the position error signal to test whether the anomaly is angular position dependent. The anomaly is associated with the corresponding command signal value and range of values to calculate the angular position and range of the apparent bearing damage. The amplitude of the anomaly is measured and associated with a relative degree of bearing damage.Type: GrantFiled: June 13, 2003Date of Patent: October 18, 2005Assignee: GSI Lumonics CorporationInventor: David C. Bown

Patent number: 6951060Abstract: In a method for the wireless transmission of a control command from a transmitting element to a measuring probe using electromagnetic signals, the control command includes at least one bit sequence which is made up of high bits and at least one low bit. The high bits are produced by the enveloping curve of a plurality of electromagnetic signals which recur with a carrier frequency. Within one bit sequence, at least one low bit is transmitted at least once between two high bits.Type: GrantFiled: January 29, 2004Date of Patent: October 4, 2005Assignee: Dr. Johannes Heidenhain GmbHInventor: Klaus Groell

Patent number: 6943676Abstract: A system for protecting the clutch of a vehicle from a harmful operating state. Included in the clutch protection system are means for monitoring the operating state of the clutch, along with means for estimating the amount of energy being dissipated by the clutch. A control unit compares the estimated amount of energy dissipated by the clutch to one or more predetermined threshold energy levels. One or more actions designed to reduce the amount of energy dissipated by the clutch are initiated when the estimated amount of energy dissipated by the clutch exceeds the one or more predetermined thresholds.Type: GrantFiled: October 1, 2002Date of Patent: September 13, 2005Assignee: Eaton CorporationInventor: William J. Mack

Patent number: 6930591Abstract: An anti-theft system for construction machines, comprising a memory which stores, as machine-side identification information, first identification information allocated construction machine by construction machine and second identification information allocated in common to plural construction machines, a first collating medium having the same identification information as the first identification information, a second collating medium having the same identification information as the second identification information, a collator which collates the identification information of the first or the second collating medium with the machine-side identification information, and an operation controller which cancels the inhibit of operation of the construction machine concerned when there is obtained a coincident collation result by the collator. With this anti-theft system, an owner of construction machines can manage the construction machines by only one type of a collating medium while preventing theft.Type: GrantFiled: May 23, 2003Date of Patent: August 16, 2005Assignee: Kobelco Construction Machinery Co., Ltd.Inventors: Tomohiko Asakage, Hisashi Kadowaki, Norihiko Hayashi, Hitoshi Hidaka

Patent number: 6914537Abstract: The present invention is directed to a method of monitoring operation data for quality control with a little possibility that a nondefective product is mistakenly determined as a defective product even if the operation data fluctuates in a large waviness curve. Every time an operation data piece for quality control is obtained, a moving average of the predetermined number of data pieces lately obtained is calculated. When the deviation of a data piece from the moving average exceeds the tolerance limit, an alarm is generated. By employing the method of the present invention for monitoring operation data such as charging time, injection time and the amount of cushion in an injection-molding machine, the accuracy of determination as to a defective or nondefective can be improved.Type: GrantFiled: May 21, 2002Date of Patent: July 5, 2005Assignee: Toshiba Machine Co., Ltd.Inventors: Akira Yoshinaga, Makoto Nishizawa, Fumiyuki Kato, Jun Koike, Hiroshi Katsuta

Patent number: 6906631Abstract: The present invention relates to a method of detecting a malfunction during a die clamping step in an injection molding machine. A reference pattern is taken which shows a relation between a die clamping force and a position of a movable platen when die clamping is normally carried out. One or more monitoring sections are set in advance with respect to that position on the basis of the reference pattern and an allowable limit value of a die clamping force in the respective monitoring sections is also set in advance in a form of a linear function of the position. The die clamping force is monitored in the respective monitoring section during a respective die clamping step and, when its value exceeds the allowable limit value, it is decided that a malfunction occurs and an alarm is issued.Type: GrantFiled: September 4, 2003Date of Patent: June 14, 2005Assignee: Toshiba Machine Co., LTDInventors: Takashi Yamazaki, Haruyuki Matsubayashi, Takeshi Abe

Patent number: 6906617Abstract: The instantaneous power consumption of an appliance is used to determine the status of the appliance, from which further actions may be taken. This invention is premised on the observation that most appliances have a characteristic power consumption pattern that can be used to determine the state of operation of the appliance. An electric coffee pot, for example, consumes high power substantially continuously during the brewing state, then reduces its power level, or power duration, or both, while keeping the pot warm, then terminates its power consumption when it is turned off. In like manner, the power consumption patterns of other appliances, such as toasters, washing machines, dryers, and so on may also be used to determine the state of each appliance. The communicated state may be used by a home-automation system to effect a variety of actions, including notifying the user, terminating the available power to the appliance, initiating an action by another appliance, and so on.Type: GrantFiled: November 17, 2000Date of Patent: June 14, 2005Assignee: Koninklijke Philips Electronics N.V.Inventor: Pieter Sierd Van der Meulen
