摘要:
Apparatus and method for a power-saving shredder, including motorized shredder blades; a shredder controller coupled to the motor controller; a timer coupled to the motor controller, and a mechanically-actuated switch (GREEN SWITCH) couples to the shredder controller. The GREEN SWITCH causes the shredder controller, the motor controller, the motorized shredder blades, and the timer to be activated. The Normally Off switch, when deactuated, causes motorized shredder blades to deactivate. A method of operating a paper shredder includes operating a mechanical actuation switch ON; applying power to paper shredder electrical and electronic elements by operating the mechanical actuation switch; setting a timer for a predetermined active period; operating motorized paper shredder blades by operating the mechanical actuation switch ON; operating the mechanical actuation switch OFF; counting by the timer the predetermined active period; and if the predetermined active period has expired, removing power from the paper shredder electrical and electronic elements.

A paper shredder having a ventilation fan; a ventilation duct tightly coupled to the ventilation fan; and air openings on the ventilation duct to blow air so that the natural fall of paper waste is disturbed. The air openings are on the ventilation duct blow air generally sideways or generally angularly to the natural fall of paper waste. The ventilation fan intake is proximate to and provides supplemental cooling air flow to, a shredder motor. A lower lid is generally above the waste bin, wherein the air openings are disposed to blow air. The shredder motor is on the lower lid. A ventilation fan intake is proximate to a shredder motor and tightly coupled to the ventilation fan, the ventilation fan intake provides supplemental cooling air flow to the shredder motor, and the air openings are on the ventilation duct blow air angularly to the natural paper waste fall.

Paper shredder thickness calibration using a Hall effect torque detector coupled to a paper shredder motor, producing a signal corresponding to the paper shredder motor rotation, a controller receives the signal and determines a paper shredder motor torque from the signal corresponding to the rotation of the paper shredder motor, with the torque corresponding to shreddant thickness. Signal is compared to predetermined maximum signal beyond which overload is signaled. Also, a method of operating a paper shredder having a rotating motor to comminute shreddant, including providing a Hall effect rotor and sensor; creating a torque signal based on a full load motor torque, and comparing the current torque signal to the full load torque signal.

摘要:
A method to diagnose weld integrity in a welding process includes monitoring a weld indentation characteristic, comparing the monitored weld indentation characteristic to a threshold weld indentation characteristic, and identifying a discrepant weld when the weld indentation characteristic comparison shows the monitored weld indentation characteristic violates the threshold weld indentation characteristic.
摘要:
A method and apparatus inspect a quality of an adhesive material used for joining a pair of work surfaces during a weld-bonding process. A pair of work pieces are at least partially bonded by a layer of the adhesive material, and the dynamic displacement of one or both electrodes is measured through a duration of the resistance welding process to determine relative moisture content of the adhesive. A control action is executed when the dynamic displacement exceeds a stored threshold value. The apparatus includes a welding device having a pair of electrodes for providing a clamping force and an electrical current necessary for forming the welded joint, a sensor for measuring a dynamic displacement of at least one of the pair of electrodes and/or another portion of the welding device during formation of the welded joint. A controller has an algorithm for determining a relative moisture using the dynamic displacement.
