Publication number: 20220299145Abstract: A catch basin trap for attachment to an opening in a side wall of a catch basin. The catch basin trap has a body with a front side for facing outside the catch basin, and a back for side facing inside the catch basin. The body defines a chamber, an inlet opening in the back side, and an outlet opening in the front side. A collapsible outlet pipe connector is attached to the outlet opening, configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end for coupling to an outlet pipe positioned outside the catch basin. The collapsed configuration stows the collapsible outlet pipe connector within the body, and the extended configuration permits watertight coupling of the discharge end to the outlet pipe. A method of installing a catch basin trap, and a method of making a concrete catch basin are also disclosed.Type: ApplicationFiled: March 16, 2022Publication date: September 22, 2022Inventors: Mario Recchia, Ian Murray Brown, Tony Parisi

Patent number: 9202043Abstract: A self-service system is provided that can automatically identify one or more existing groups to which a user can self-select to access a resource. The self-service system can identify any suitable existing group without requiring an administrator to predefine groups according to roles. In some implementations, the system intelligently identifies one or more suitable groups for a user from a list of available groups by analyzing a set of rules or criteria. For instance, the system can perform a weighted analysis of various rules and/or criteria to automatically and dynamically identify groups that have a closest fit to the access rights needed or requested by the user. Further, the system can evaluate certain best or preferred grouping practices to identify suitable groups. As a result, in certain embodiments, the self-service system alleviates planning burdens on administrators and provides greater flexibility in providing users with access to resources.Type: GrantFiled: January 7, 2014Date of Patent: December 1, 2015Assignee: Dell Software Inc.Inventors: Stephen Brian Dinn, Ian Murray Frosst

Publication number: 20150205822Abstract: A method for contact management comprises retrieving, using a mobile electronic device of a user, contact information from multiple external sources. The method next comprises storing said contact information in a memory location of said mobile electronic device. Next, the method comprises determining with a computer processor whether contact information from a portion of said multiple sources at least partially overlaps with contact information from a remainder of said multiple sources. The method next comprises either merging the contact information to generate a consolidated contact record or splitting the contact information to generate split contact records based on the determining the overlap. And then the method comprises storing said consolidated contact record or split contact records in a memory location of said mobile electronic device.Type: ApplicationFiled: January 16, 2015Publication date: July 23, 2015Inventors: Ankur Jain, Purshotam Rajani, Sinan Aral, Daniel O'Shea, Chetan Surpur, Ian Murray, Ryan Mick, Clara Zavani, Joe Dao, John Ullman, Kenny Liou, Jacob Topper, Jaclyn Chen, Arielle Zuckerberg, Daniel Pourbaba, Jonathan Shriftman, Jacob Medwell, David Wyler

Publication number: 20150039093Abstract: A prosthetic femoral implant for use in a hip joint, as a ball and socket type joint, is disclosed. The implant includes a modular neck having a variety of adjustable positions to adjust the lateral offset and version angle of the femoral implant in relation to the femur. The implant further includes a broad, full collar for providing a compression force increasing the interdigitation between the interface of the bone, implant and cement. The implant also includes a stem having a depression having a roughened porous surface for resisting the increased torsional loads placed on the implant due to the increased lateral offset and version angle. The stem further comprises three distinct zones, each zone having its own roughened surface creating a tripartite differential porosity.Type: ApplicationFiled: April 7, 2014Publication date: February 5, 2015Applicant: DJO Surgical | Chattanooga GroupInventors: Timothy McTighe, Ian Murray, Hugh U.
