Patent number: 6685074Abstract: A dispensing apparatus and method are disclosed for dispensing sheet material from at least one roll of the sheet material. Dispensing is transferred from a stub roll to a reserve roll automatically in response to sensing a predetermined quantity of the stub roll. An isolating element is provided to lift the reserve roll out of contact with dispensing rollers during dispensing of sheet material from the stub roll, and a nipping element is provided to nip sheet material of the reserve roll when dispensing is transferred from the stub roll to the reserve roll. A cam controls movement of both the isolating element and the nipping element. Structure is also provided for sensing the diameter of the reserve roll of sheet material and providing an indication when the reserve roll is a predetermined diameter. The dispenser is quiet and capacity efficient.Type: GrantFiled: February 21, 2002Date of Patent: February 3, 2004Assignee: Fort James CorporationInventors: Dale T.

Publication number: 20030221320Abstract: By providing a movable, separate, and independent blade member which is normally maintained in a stowed and hidden position, a combined, integrated, multi-purpose scissors and box cutting product is achieved. In the present invention, the combined, integrated, scissors and box cutting product incorporates two arm members pivotally mounted to each other, with each arm member incorporating a blade portion and a handle portion. In the preferred construction, the movable blade member is retained within one handle portion of one arm member of the combined, integrated, scissors and box cutting product, with the movable blade member being deployed for use only upon activation by the user. In this way, the blade member remains concealed and hidden within the handle portion of the arm member in order to prevent unwanted or accidental contact of the blade member when not desired.Type: ApplicationFiled: June 3, 2002Publication date: December 4, 2003Inventors: David Carpenter, Christoper Aiston

Publication number: 20020095656Abstract: A method and computer software architecture is presented for facilitating modification of execution of a software application without impacting the integrity of the original software. The present invention defines an inter-component messaging service which brokers or receives, evaluates and directs messages between components of the architecture. The architecture further integrates functionality into the individual components which re-directs a request back to the messaging service prior to completion of the functionality in the requested original component in order to determine the presence of any concerned extension components that have registered with the messaging service thereby making known their interest in having their functionality explored prior to completion of the execution of the requested component.Type: ApplicationFiled: September 14, 2001Publication date: July 18, 2002Inventors: Lori Clark, Harold Weir, Derek Jones, Garrette Pease, David Carpenter

Patent number: 6226177Abstract: The invention is a friction hinge assembly for a laptop computer which has a high thermal conductivity. The assembly includes a base element, a base element fixed to the base of the computer and to which an axially aligned base heat pipe is coupled. The assembly also includes a lid element fixed to the lid of the computer. The lid element has a body portion and a rotatable sleeve attached to the lid and which receives a lid heat pipe. The base and lid elements are pre-assembled selectively fastenable to one another for ease of assembly of the lid to the base, and in order to control the frictional torque produced by the hinge during operation.Type: GrantFiled: June 8, 1999Date of Patent: May 1, 2001Assignee: TorqMaster, Inc.Inventors: Edward T. Rude, David A. Carpenter

Patent number: 5918348Abstract: The present invention provides a small, cylindrical hinge, or pivoting pin, which can be configured to produce various profiles of torque versus angle. The desired profile of torque versus angle is achieved by the shapes of the hinge shaft and the spring plates of the hinge. Detents at one or more angular positions can be achieved, with or without frictional damping torque at other angles. The friction of our hinge is produced symmetrically about the hinge axis, eliminating the problems associated with asymmetric construction.Type: GrantFiled: January 6, 1998Date of Patent: July 6, 1999Assignee: TorqMaster, Inc.Inventors: David A. Carpenter, Mikhail Gelfand, Edward T. Rude

Patent number: 5771540Abstract: A hinge that provides equilibration and variable friction for a display screen or a laptop lid. In the preferred embodiment, a torsion rod provides a restoring force which increases as the lid is moved either direction from its vertical position. A friction hinge, of well know design, uses a spring band about a shaft. One end of the torsion rod is coupled to the end of the band of the friction hinge, so that the moment in the torsion rod increases or decreases the moment in the spring band of the hinge, modifying the frictional torque accordingly. This allows the frictional torque to be low as the lid is first opened, and larger as the display reaches the useful range of its motion.Type: GrantFiled: January 22, 1997Date of Patent: June 30, 1998Assignee: TorqMaster, Inc.Inventors: David A. Carpenter, Mikhail Gelfand, Edward T. Rude

Patent number: 5052394Abstract: In ultrasonic echoscopy, when an object to be examined has overlying layers of a medium (for example, fat, muscle, skin or bone) which have different ultrasonic transmission characteristics from those of the object, the echogram of the object is usually distorted. To reduce that distortion, the present invention uses a transducer comprising an array of ultrasonic transducer elements operated in a higher resolution mode than its normal imaging mode, to obtain information about the geometry of the overlying layers. Using this information and a knowledge of the transmission characteristics of the overlying layers, amplitude and phase corrections are calculated, to enable the transducer, when operated in its normal imaging mode, to generate a required beam of ultrasound. The corrections are then applied and an echogram of the object, with reduced distortion, is obtained while operating the transducer in its normal imaging mode.Type: GrantFiled: March 28, 1989Date of Patent: October 1, 1991Assignee: Commonwealth Scientific and Industrial Research OrganizationInventors: David A. Carpenter, George Kossoff

Patent number: 4289140Abstract: Echoscopes incorporating signal processing circuits capable of providing a more complete and useful display of information received as a train of electrical signals. In one circuit, which is essentially a compression amplifier, the amplitude range of the input signal is limited by way of two or three amplitude limiting stages and an adder connected to sum the output of the first and last stages provides an advantageous output to input characteristic for the circuit.The second circuit includes filter means and derivating means to separately process the input signal, and an adder to combine the outputs of these means to obtain a signal of enhanced utility.Type: GrantFiled: August 31, 1979Date of Patent: September 15, 1981Inventors: David A. Carpenter, George Kossoff, George D. Radovanovich
