Patent number: 12036664Abstract: An end effector is disclosed that is configured for connection to a robotic unit used to manipulate a door of a vehicle (e.g., during vehicle painting). The end effector includes a base plate; a sensor that is supported by the base plate; and a piston that is configured for engagement with the door. The piston is operatively connected to an interrupter such that movement (displacement) of the piston causes corresponding movement (displacement) of the interrupter between a first position, in which the interrupter is positioned in alignment with a signal transmitted across the sensor to interfere with the signal and thereby interrupt circuit completion, and a second position, in which the interrupter is out of alignment with the signal transmitted across the sensor to permit circuit completion and thereby inform the robotic unit that the door is present and engaged with the end effector.Type: GrantFiled: July 30, 2021Date of Patent: July 16, 2024Assignee: Nissan North America, Inc.Inventors: Andrew Williamson, Gregory Michel, Travis Fritsche, David Calvert, Terry Cox

Patent number: 8578564Abstract: A handle for receiving a cleaning article, such as a dusting device. The handle has one or more tines which are disposed outboard of a reference plane. This geometry provides a friction fit for receiving a removable cleaning device on the tines, without substantial interference. The friction fit retains the cleaning article on the handle during use while reducing tearing which occurs during installation.Type: GrantFiled: November 5, 2009Date of Patent: November 12, 2013Assignee: The Procter & Gamble CompanyInventors: Nicola John Policicchio, David Calvert Rucker, David William Schuller, Richard Christopher Hagee, Diana Woehnl Juratovac, Richard Lee Lane, Ryan Robert Berger, Ranier Bernhard Teufel

Publication number: 20030040498Abstract: The limited efficacy and/or toxicity of conventional therapies for many types of human cancers underscores the need for development of safe and effective alternative treatments. Towards this goal, the invention describes the direct oncolytic activity of RNA-based vectors derived from poliovirus, termed replicons, which are genetically incapable of producing infectious virus. Replicons of the invention are cytopathic in vitro for human tumor cells originating from brain, breast, lung, ovaries and skin (melanoma). Injection of replicons into established xenograft flank tumors in scid mice resulted in oncolytic activity and extended survival. Inoculation of replicons into established intracranial xenografts tumors in scid mice resulted in tumor infection and extended survival. Histological analysis revealed that replicons infected tumor cells at the site of inoculation and, most importantly, diffused to infect tumor cells which had metastasized from the initial site of implantation.Type: ApplicationFiled: March 13, 2002Publication date: February 27, 2003Inventors: David Calvert Ansardi, Casey Dolan Morrow, Donna Coker Porter
