Publication number: 20110060439Abstract: A customer sends a CAD file for the part to be manufactured to the system. The system assesses the CAD file to determine various pieces of manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be machined in two opposing orientations in a 3 axis CNC machine. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities or parts per workpiece block, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts, which may include both molded parts and total profiled machined parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer.Type: ApplicationFiled: October 12, 2010Publication date: March 10, 2011Applicant: PROTO LABS, INC.Inventors: Lawrence J. Lukis, Christopher Walls-Manning, Mark R. Kubicek

Patent number: 7630783Abstract: A computer program analyzes a CAD file provided by a customer of a custom part to be injection molded. Feedback from the analysis is provided to the customer through a rendering of the part. Rather than merely communicating using color as applied to the rendering file and separate text, the invention applies one or more symbols as “decals” to the rendering of the part provided to the customer. In one preferred embodiment, the symbols are chevrons or arrows which indicate the direction of additional draft needed on particular faces for the part to be sufficiently manufacturable. The symbols are sized appropriately for the size of the face to which they are applied, and are oriented to match the orientation of the face. The symbols may also indicate other information, such as the magnitude of draft needed, magnitude of thickness required, the surface finish to be applied at that location, or time or location based properties of the injection molding process.Type: GrantFiled: January 24, 2006Date of Patent: December 8, 2009Assignee: Proto Labs, Inc.Inventors: Christopher Walls-Manning, Kevin R. Crystal, John M. Gilbert

Publication number: 20090125418Abstract: A customer sends a CAD file for the part to be molded to the system. The system assesses the CAD file to determine various pieces of mold manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be manufactured in a two-piece, straight-pull mold, and whether the mold can by CNC machined out of aluminum. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer.Type: ApplicationFiled: January 15, 2009Publication date: May 14, 2009Applicant: PROTO LABS, INC.Inventors: Lawrence J.

Patent number: 7123986Abstract: A customer sends CAD files for two or more parts to be molded in a family to the system. The system provides the customer with a quotation form that allows the customer to select several family-level parameters which are independent of the shape of the part, such as material and delivery date. The quotation also allows the customer to select several part-level parameters which are independent off the shape of the part, such as quantity of each part and surface finish. The system assesses the CAD files to determine savings which can be achieved by molding the parts as a family, with multiple parts in the same mold block. If possible, the system machines cavities for the multiple parts into a single mold block, passing on reductions in cost to the customer both in the quote and in the final product delivery.Type: GrantFiled: March 7, 2005Date of Patent: October 17, 2006Assignee: The Protomold Company, Inc.Inventors: Lawrence J.

Patent number: 7089082Abstract: A first customer provides a CAD file defining the surface profile for a part to be molded to the system, and a second customer does the same for a second part. The system determines whether the materials match and the run dates overlap, thereby qualifying the parts for use in a multi-customer mold block. The system assesses the part surface profile (which could have any of a virtually infinite number of shapes) of the parts submitted and lays out the parts from multiple customers on one or more multi-customer mold blocks. Savings are generated, such as by reducing redundancies in press clean-up, in set-up, in tooling, and in surface finishing. Due to these savings, the system provides a quotation of the part to at least one of the customers which differs from the quotation that would be provided if each part was run independent of parts of other customers.Type: GrantFiled: April 25, 2005Date of Patent: August 8, 2006Assignee: The Protomold Company, Inc.Inventors: Lawrence J.

Publication number: 20050166647Abstract: A multi-point door lock assembly has a central lock and an extension bolt for securing the door to a door frame. The assembly has an actuator positioned at the central lock and moveable between a first and second position along an axis. The assembly further has an elongated extension bolt residing along a bolt axis. The actuator and the bolt are secured in a configuration that displaces the axis of the bolt in spaced relationship from the axis of the actuator by an adaptor having a body length. The adaptor has a first end connected to the actuator and a second end connected to the extension bolt, and an intermediate portion between the first and second ends configured to displace the bolt axis for the bolt to pass through an interior portion of an associated door member.Type: ApplicationFiled: January 29, 2004Publication date: August 4, 2005Inventors: Christopher Walls, Lyle Hansel

Publication number: 20040199838Abstract: An integrated circuit or other electronic circuitry is tested by arranging device pins into multiple-pin groups, and permitting the device pins of the group to share a single tester channel of a piece of test equipment. More particularly, a group comprising a plurality of device pins of the electronic circuitry is designated, and assigned to one of a plurality of tester channels in the test equipment. A test may then be performed on the electronic circuitry, via the assigned tester channel, utilizing at least a subset of the device pins in the designated multiple-pin group. Advantageously, the invention allows high pin count integrated circuits to be tested using inexpensive test equipment platforms.Type: ApplicationFiled: March 19, 2003Publication date: October 7, 2004Inventors: Paul William Rutkowski, Larry Christopher Wall

Patent number: 5924435Abstract: A method of energizing an electromagnetically operable valve which comprises a valve member movable into engagement with a seating when a winding is energized comprising connecting the winding to a DC supply to achieve a rapid rate of rise of current. The current is controlled at the peak value and is then reduced to a low value after an initial movement of the valve member. The valve member continues its movement towards the seating and the current is restored prior to engagement of the valve member with the seating to substantially eliminate bouncing of the valve member away from the seating.Type: GrantFiled: November 9, 1995Date of Patent: July 20, 1999Assignee: Lucas Industries public limited companyInventors: Robin Christopher Wall, Brian William Tumber
