Patent number: 6591157Abstract: In an apparatus for notifying machine operators of the necessity for preventive maintenance, predetermined difficulty factors corresponding to the severity of particular machine operating conditions are stored in the memory of a controller. Maximum acceptable values are also stored in the controller's memory. Sensors, detect any one of a number of different machine operating parameters and the duration for which the machine functions under a particular operating condition. These parameters are quantified with respect to one of the difficulty factors most closely related to the operating condition. The quantified parameters are accumulated and compared with the appropriate maximum value. When the accumulated quantified parameters reach the maximum value, an operator is alerted to the fact that maintenance is needed.Type: GrantFiled: March 9, 2000Date of Patent: July 8, 2003Assignee: Gerber Technology, Inc.Inventors: Joseph R.

Patent number: 6370969Abstract: In a method of inertia-testing movable machine components, a machine motor is powered to impart constant motion on various components. The power supply to the motor is then cut, causing the moving components of the machine to continue moving, due to inertia or angular momentum, until a resting state is achieved. The time required to reach a resting state is measured and recorded for comparison to predetermined data indicative of a normally operating machine. If the time required to achieve a resting state varies from the predetermined data by a substantial amount, it may be indicative of a damaged, worn or maladjusted component.Type: GrantFiled: November 4, 1999Date of Patent: April 16, 2002Assignee: Gerber Technology, Inc.Inventors: Kevin A.

Patent number: 5250138Abstract: A top ply labeler includes a presser foot and applicator pad which are arranged for relative movement to one another travel along a rectilinear path as the ram of an applicator cylinder is extended and retracted toward and away from the top surface of a lay-up of sheet material whereby a label carrying identification information are applied at predetermined positions. The applicator cylinder is mounted to the applicator backplate for relative vertical movement toward and away from the top ply surface to maintain the labeller at a desired elevation above the top ply. A vane carried by the pressure foot is detected by a sensor carried on the applicator pad when the pressure foot contacts the surface of a top ply. As the applicator pad continues its downward movement, the pressure foot and vane move relative to the applicator pad until such time as the vane is detected by the applicator pad sensor to apply to the label and stop the downward movement.Type: GrantFiled: April 8, 1991Date of Patent: October 5, 1993Assignee: Gerber Garment Technology, Inc.Inventors: Richard S.

Patent number: 4204268Abstract: An auxiliary commutation circuit to compensate for transient type overload conditions of an inverter comprises a pair of oppositely charged capacitors controlled by separate switches, each operable at a particular time during the conduction cycle of the main thyristors to provide additional stored energy for commutation during overcurrent conditions. A current detector senses the load current and provides a signal to an auxiliary gate whenever the rate of change in the load current or its absolute magnitude exceeds a preselected value. In response to the overcurrent signal and a timing signal, the auxiliary gate renders the appropriate switch operative coupling the charged auxiliary capacitor in parallel with the primary commutation capacitor so that the combined electrical energy stored on both capacitors is available for commutation. After the commutation period the auxiliary gate maintains the switch in its open state for a sufficient period of time to allow the auxiliary capacitor to be recharged.Type: GrantFiled: December 26, 1978Date of Patent: May 20, 1980Assignee: United Technologies CorporationInventor: Joseph R.
