Publication number: 20240068135Abstract: Interlacing equipment may be used to form fabric and to create a gap in the fabric. The fabric may include one or more conductive strands. An insertion tool may be used to align an electrical component with the conductive strands during interlacing operations. A soldering tool may be used to remove insulation from the conductive strands to expose conductive segments on the conductive strands. The soldering tool may be used to solder the conductive segments to the electrical component. The solder connections may be located in grooves in the electrical component. An encapsulation tool may dispense encapsulation material in the grooves to encapsulate the solder connections. After the electrical component is electrically connected to the conductive strands, the insertion tool may position and release the electrical component in the gap. A component retention tool may temporarily be used to retain the electrical component in the gap as interlacing operations continue.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Inventors: Kyle L. Chatham, Kathryn P. Crews, Didio V. Gomes, Benjamin J. Grena, Storrs T. Hoen, Steven J. Keating, David M. Kindlon, Daniel A. Podhajny, Andrew L. Rosenberg, Daniel D. Sunshine, Lia M.

Patent number: 6527751Abstract: A manually operated hydraulic syringe includes a syringe barrel. The syringe barrel has an interior surface bounding a chamber extending from a first end to an opposing second end. A manual plunger has a distal end slidably disposed within the first end of the chamber. A hydraulic plunger is slidably enclosed within the second end of the chamber. Sealed in substantial isolation within the syringe barrel is a hydraulic fluid, such as water or oil. Coupled to the distal end of the syringe barrel is a nozzle or cartridge in which a dispensing material, such as a high viscosity fluid, can be selectively disposed. Manual advancement of the manual plunger within the first chamber results in pressurization of the hydraulic fluid. In turn, the pressurized hydraulic fluid advances the hydraulic plunger under a force greater than the force applied to the manual plunger. Advancement of the hydraulic plunger within the syringe body functions to dispense the dispensing material from the attached nozzle or cartridge.Type: GrantFiled: December 20, 2000Date of Patent: March 4, 2003Assignee: Ultradent Products, Inc.Inventors: Dan E. Fischer, David V. Fischer, Bruce S. McLean, Samuel A. Howard, Andrew Wight

Patent number: 6425885Abstract: A manually operated hydraulic syringe includes a syringe barrel having an interior surface. The interior surface bounds a first chamber having a first transverse cross-sectional area and a second chamber having a second transverse cross-sectional area. The first chamber is in fluid communication with the second chamber and the transverse cross-sectional area thereof is smaller than the transverse cross-sectional area of the second chamber. A first plunger has a distal end slidably disposed within the first chamber. A second plunger is slidably enclosed within the second chamber. Sealed in substantial isolation within the syringe barrel between the first and second plungers is a hydraulic fluid, such as water or oil. Rotatably coupled to the distal end of the syringe body is a nozzle or cartridge in which a dispensing material, such as a high viscosity fluid, can be selectively disposed.Type: GrantFiled: December 20, 1999Date of Patent: July 30, 2002Assignee: Ultradent Products, Inc.Inventors: Dan E.

Patent number: 5697918Abstract: A system and method for storing in bulk and readily dispensing a dental composition includes a prefilled bulk storage syringe, storage container, or squeezable tube that is capable of storing multiple doses of the composition for dispensing into a dose administration syringe. The discharge end of the bulk storage syringe, storage container, or squeezable tube can be coupled directly to the discharge end of the dose administration syringe without an adaptor, allowing the dental composition to be readily transferred directly to the dose administration syringe. The dental composition can then be readily administered to a desired area from the dose administration syringe after the bulk storage syringe, storage container, or squeezable tube has been decoupled therefrom.Type: GrantFiled: June 7, 1995Date of Patent: December 16, 1997Assignee: Ultradent Products, Inc.Inventors: Dan E. Fischer, David V. Fischer

Patent number: 5618273Abstract: A syringe apparatus is disclosed for delivering solid, yet pliable materials, such as dental composites. The syringe apparatus of the present invention comprises an unthreaded barrel means for containing the material. The unthreaded barrel means has an inlet end, an outlet end, and an enlarged finger grip at the inlet end. The syringe apparatus also comprises means for slidably engaging the finger grip of the barrel means, the engaging means having a threaded throughbore. The syringe apparatus further comprises a plunger means for movement through the barrel means. The plunger means has a threaded portion that is complementary to the threaded throughbore of the engaging means, such that the plunger means may be advanced into the barrel means at the inlet end by applying an external rotational force to the plunger means relative to the barrel means, thereby effecting delivery of the material at the outlet end of the barrel means.Type: GrantFiled: May 15, 1996Date of Patent: April 8, 1997Assignee: Ultradent Product, Inc.Inventor: David V.

Patent number: 5558230Abstract: A container shaped to allow a dental technician to avoid touching or contaminating a dental implant and healing screw stored therein while placement of these at a dental surgical site. The container has a carrier for storing the implant and healing screw. A transparent hood seals the carrier from the ambient. The dental implant is held at an end thereof within the carrier with its longitudinal axis normal to the longitudinal axis of the healing screw in its position in a cavity in the carrier. A tool passage in the carrier provides access to the cavity for a placement tool that is attached to the healing screw in order to remove the same from the carrier. A cylindrical base on the carrier, terminated at opposite ends thereof by radially projecting flanges, provides a gripping surface for the thumb and index finger of a dental technician during removal of the implant and healing screw from the carrier.Type: GrantFiled: June 7, 1995Date of Patent: September 24, 1996Assignee: Ultradent ProductsInventors: David V.

Patent number: 5445523Abstract: Syringe assembly apparatus and associated methods are provided for use in dispensing viscous materials, such as dental compositions, in a controlled fashion. The preferred embodiment of the syringe assembly of the present invention includes a syringe body of conventional fashion, having a passageway therethrough and a discharge port communicating with the passageway. An adapter member is provided which nests within the syringe body passageway, the adapter member having a bore passing through the length thereof for receiving a viscous material to be dispensed. When the adapter is nested within the passageway of the syringe body, the bore communicates with the discharge port of the syringe body. An important feature of the invention is that the bore has a diameter substantially the same as the diameter of the discharge port at the location where the discharge port communicates with the bore.Type: GrantFiled: September 3, 1993Date of Patent: August 29, 1995Assignee: Ultradent Products, Inc.Inventors: Dan E.
