Publication number: 20160112111Abstract: In one implementation, a wireless communication terminal includes a primary antenna array and a first controller configured to steer a main beam of the primary antenna array in a desired direction. The wireless communication terminal also includes an auxiliary antenna array and a second controller configured to control complex weights to be applied by at least some antenna elements of the auxiliary antenna array to corresponding variants of a second signal received by the at least some auxiliary antenna elements. Furthermore, the wireless communication terminal includes at least one signal combiner configured to combine variants of the second signal received from auxiliary antenna elements into an interfering signal that models interference from a co-located wireless communication terminal and subtract the interfering signal from variants of the first signal received from antenna elements of the principal antenna array to produce an interference mitigated signal.Type: ApplicationFiled: December 30, 2015Publication date: April 21, 2016Inventor: Jeffrey Francis Bull

Publication number: 20160096228Abstract: A cutting insert for a cutting tool is described. The cutting inserts generally square-shaped with two opposing surfaces and four peripheral side surfaces. Cutting edges are formed at the intersection between the first and second surfaces and the peripheral side surfaces. Each cutting edge is divided into a first portion, a second portion and a radius blend. The first portion has a length, L1, and the second portion has a length, L2, that is shorter than the first portion such that the radius blend is not located at a midpoint of the cutting edge, thereby increasing a height of the ninety-degree shoulder that can be cut by the cutting insert.Type: ApplicationFiled: October 6, 2014Publication date: April 7, 2016Applicant: KENNAMETAL INC.Inventors: Brad Daniel Hoffer, Jeffrey Francis Kovac

Publication number: 20150326399Abstract: The present invention uses Server-based Certificate Validation Protocol (SCVP) to validate the public key digital signature certificate of an email signer (or the public key encryption certificate of an email recipient) by using a modified SCVP server such that a trustworthiness indicator based on certificate policies is included in an SCVP server response that maps the certificate policies asserted in the public key certificate of the email signer (or email recipient(s)) to graphically represent the degree of trust that can be attributed to the identities bound to public key certificates containing one or more certificate policies. The graphical representation of a trust level may appear directly in an email client and is based on the level of trust attributable to the binding between the public key distributed via a public key certificate (for signing or encryption) and the identity/attributes of the “subject” or “entity” contained in that certificate.Type: ApplicationFiled: May 12, 2014Publication date: November 12, 2015Inventors: Jeffrey Dean Nigriny, Jeffrey Francis Barry, Stephen P.

Publication number: 20150266112Abstract: A cutting tool includes a pocket with a top wall, a bottom wall, a side wall and a rear wall. The cutting tool has an insert cartridge and a wedge clamp. The threaded member exerts a force vector in a radial direction when threaded into the wedge clamp to place the cutting tool in a locked condition, and the wedge clamp exerts a force vector into the body of the cutting tool radially inward of an adjacent pocket, thereby reducing deflection of the adjacent pocket when the cutting tool is placed in the locked condition.Type: ApplicationFiled: March 19, 2014Publication date: September 24, 2015Applicant: Kennametal Inc.Inventors: Michael Glenn Morrison, Jeffrey Francis Kovac

Publication number: 20150196959Abstract: A cutting tool includes a pocket with a top wall, a bottom wall, a side wall and a rear wall. The cutting tool has a wedge clamping system that includes an insert cartridge and a clamp wedge. The insert cartridge includes a recess that interacts with a protrusion on the clamp wedge in such a way that the clamp wedge exerts a force vector in an axial direction when the clamp wedge is threaded into the pocket, thereby reducing deflection of an adjacent pocket of the cutting tool when the cutting tool is placed in a locked condition.Type: ApplicationFiled: January 14, 2014Publication date: July 16, 2015Applicant: Kennametal Inc.Inventors: Michael Glenn Morrison, Jeffrey Francis Kovac

Patent number: 9079257Abstract: An indexable cutting insert includes a top surface, a bottom surface, a plurality of peripheral side surfaces, and a plurality of cutting edges formed at an intersection between said top surface and plurality of side surfaces. A plurality of triangular-shaped serrations are positioned along the cutting edges, each serration comprising an apex and a pair of side surfaces that meet at a vertex. The serrations provide the cutting edges with both a positive axial rake angle and a negative axial rake angle, thereby reducing delamination when machining a composite material.Type: GrantFiled: January 28, 2013Date of Patent: July 14, 2015Assignee: KENNAMETAL INC.Inventor: Jeffrey Francis Kovac
