Patent number: 11614748Abstract: A materials handling vehicle operating system is provided comprising a tag layout where a plurality of entry/exit tag sets are arranged along a travel path at different ones of the entry/exit thresholds of a restricted navigation zone. Each entry/exit tag set comprises a release tag, a restriction tag, and an indicator tag. The indicator tag is positioned between the restriction tag and the restricted navigation zone. The restriction tag is positioned between the release tag and the indicator tag. The tag reader and the reader module cooperate to compare identified tag data with stored tag data and initiate a remediation operation when an indicator tag is identified in place of a restriction tag. Tag layouts for one-way and two-way travel into and out of a restricted navigation zone are also contemplated.Type: GrantFiled: September 15, 2020Date of Patent: March 28, 2023Assignee: Crown Equipment CorporationInventors: Daniel Douglas Walton, Aaron Louis Williams

Patent number: 9601604Abstract: An electronic device and a method of fabricating an electronic device are disclosed. The device includes a body of semiconductor material, and a conductive material defining at least three conducting contacts to form respective terminals. The semiconductor material and the conducting contacts overlap at least partially to define the device, so that the electrical characteristics of the device between any pair of terminals correspond to those of a varistor. The body of semiconductor material may be a layer deposited by printing or coating. The varistor characteristics between each pair of terminals enable switching of an electrical current between one terminal and any two other terminals in such a manner that when there is a positive current into a first terminal, there is a negligible current through a second terminal at which a positive potential is applied and a positive current out of a third terminal which is held at a negative potential with respect to the second terminal.Type: GrantFiled: September 20, 2013Date of Patent: March 21, 2017Assignee: PST Sensors (Proprietary) LimitedInventors: David Thomas Britton, Margit Haerting, Stanley Douglas Walton

Patent number: 7650530Abstract: EEH methods are used during the boot process to actively disable a defective PCI adapter, thereby allowing the system boot to continue without disruption. This allows faulty adapters to be present in the machine without interrupting the boot process. The slots appear to be empty and the devices/adapters residing therein can be actively “hot swapped” out without altering the rest of the machine state.Type: GrantFiled: September 30, 2002Date of Patent: January 19, 2010Assignee: International Business Machines CorporationInventors: Bradley Ryan Harrington, David Lee Randall, Scott Douglas Walton, David Ross Willoughby

Publication number: 20070169439Abstract: Computer assisted systems, methods and mediums for filling one or more orders. One embodiment of the present invention is a system that includes an order consolidation station configured to receive at least one bottle containing pills individually counted and/or at least one package containing pharmaceutical products without having been designated for any of the orders when the package was created and/or at least one literature pack optionally including patient specific information. The order consolidation station is further configured to combine automatically the received bottle and/or package and/or literature pack into a container to be sent to a recipient including, for example, mail order pharmacies, wholesalers and/or central fill dealers for subsequent distribution or sale including retailer distribution or sale. The bottle is specifically designated for the order, and the order generally includes at least one prescription for the package.Type: ApplicationFiled: March 5, 2007Publication date: July 26, 2007Applicant: Medco Health Solutions, Inc.Inventors: Dennis Rice, James McErlean, E. Hess, P. Shupert, Chih-Jen Leu, Robert Howell, Michael Szesko, Andrew Booler, Peter Monkhouse, Douglas Walton, Michael Bell, Christopher Lasher, Thomas Bonkenburg

Publication number: 20070120654Abstract: An indicator light assembly is provided for use with a towed object having a substantially planar rear end, at least one substantially planar side orthogonal to the end, and an intersection between the side and the end. The indicator light assembly includes a transmitting assembly and at least one tail-light assembly. The transmitting assembly transmits wireless signals corresponding to vehicular indicator light signals when coupled to an indicator light energizing circuit of the vehicle. The tail-light assembly includes a support structure, as well as an indicator light, a receiver, and a controller attached to the support structure. The support structure includes a first planar portion and a second planar portion orthogonal to the first portion, where at least one of the first and second portions includes a plurality of apertures for receiving fasteners. The receiver receives the wireless signals.Type: ApplicationFiled: November 22, 2006Publication date: May 31, 2007Inventor: Douglas Walton

Patent number: 6950978Abstract: A method, apparatus, and computer implemented instructions for processing and recovering from soft errors in computer array with a parity error checking design in a data processing system. In response to an occurrence of a parity error, processor status information is stored to form stored processor information. A determination is made as to whether the parity error is a recoverable parity error using the stored processor information. In response to the parity error being a recoverable parity error, a recovery action is performed. The specific action taken varies depending on the type of error.Type: GrantFiled: March 29, 2001Date of Patent: September 27, 2005Assignee: International Business Machines CorporationInventors: Richard Louis Arndt, Alongkorn Kitamorn, Edward John Silha, Scott Douglas Walton, David R.
