Patent number: 10158675Abstract: An alert source issues security alerts to an identity provider, which acts as a gatekeeper to a secure resource. Each security alert is associated with an alert user identity and a security threat. When a user identity requests access to the secure resource, the identity provider may look up security alerts associated with the user identity, such as by matching up the user identity with the alert user identity associated with each alert. Based on any discovered security alerts that correspond to the user identity and a pre-defined security policy, the identity provider may perform various security actions on the user identity. The identity provider may provide access to the secure resource without containing the user identity if there are no discovered security alerts associated with the user identity, or if the discovered security alerts pose a minor threat.Type: GrantFiled: September 15, 2017Date of Patent: December 18, 2018Assignee: SecureAuth CorporationInventors: Keith Martin Graham, Stephen Garnett Cox

Patent number: 9790661Abstract: A hydraulic system for a machine is disclosed. The hydraulic system may have a tank configured to hold a supply of fluid, a pump configured to draw fluid from the tank and pressurize the fluid, a first cylinder operatively connected between a first side of a work tool and an undercarriage of the machine, and a second cylinder operatively connected between a second side of the work tool and the undercarriage of the machine. The hydraulic system may also have a first electro-hydraulic valve associated with the first cylinder and configured to selectively regulate a flow of pressurized fluid to the first cylinder independently of the second cylinder, and a second electro-hydraulic valve associated with the second cylinder and configured to selectively regulate a flow of pressurized fluid to the second cylinder independently of the first cylinder.Type: GrantFiled: November 24, 2014Date of Patent: October 17, 2017Assignee: Caterpillar Inc.Inventors: Timothy L.

Each security alert is associated with an alert user identity and a security threat. When a user identity requests access to the secure resource, the identity provider may look up security alerts associated with the user identity, such as my matching up the user identity with the alert user identity associated with each alert. Based on any discovered security alerts that correspond to the user identity and a pre-defined security policy, the identity provider may perform various security actions on the user identity. For example, the identity provider may contain a user identity associated with high-risk and/or high fidelity security alerts. The identity provider may deny the user identity access to the secure resource, or the identity provider may request additional authentication factors associated with the user identity before access to the secure resource is provided.Type: GrantFiled: March 4, 2016Date of Patent: September 19, 2017Assignee: SecureAuth CorporationInventors: Keith Martin Graham, Stephen Garnett Cox

Patent number: 8833871Abstract: A ground engaging track for a track-type machine includes a set of identical standard track shoes each having a relatively narrow shoe footprint, and a sweeping track shoe having a relatively wide shoe footprint. The sweeping track shoe is connectable via track links with the standard track shoes in an endless chain configuration such that the sweeping track shoe juts outwardly of the standard track shoes, for sweeping debris from a clearance between the track and a main frame of the track-type machine. The sweeping track shoe includes bolting apertures formed therein and communicating between an upper shoe surface and a ground contacting shoe surface, the bolting apertures being arranged in a directional link bolting pattern. The directional link bolting pattern defines a minor shoe axis and a major shoe axis, and the sweeping shoe body may be configured such that an inboard sweeping edge is spaced further than an outboard edge from the minor shoe axis.Type: GrantFiled: December 14, 2010Date of Patent: September 16, 2014Assignee: Caterpillar Inc.Inventors: Kenneth Nebergall, Stephen Garnett, Britta A.

Publication number: 20070251740Abstract: A method is provided for controlling an electric drive work machine including an engine and an electric motor that provides power to enable the work machine to travel across a surface terrain at certain ground speeds. In one embodiment, the method may include detecting a reverse directional shift of the work machine causing the work machine to travel in a reverse direction. Further, the method may include performing an engine speed reduction process that reduces a current speed of the engine based on the detected reverse directional shift without reducing a ground speed of the work machine while traveling in the reverse direction.Type: ApplicationFiled: April 25, 2007Publication date: November 1, 2007Inventors: Michael Betz, Stephen Garnett, Chih Liang

Publication number: 20060020383Abstract: A method is provided for controlling power provided by a drive train system of a work machine, which includes an engine that provides engine power to a generator that, in turn, provides generator power to a motor. The motor provides ground power to a travel mechanism that enables the work machine to travel across a terrain surface. In one embodiment, the method includes adjusting operation of the motor based on a determined ground speed of the work machine. Based on the adjusted motor operations, the operation of the generator is adjusted. Also, the operation of the engine is adjusted such that the engine produces an amount of engine power that meets a load demand corresponding to the adjusted operation of the generator.Type: ApplicationFiled: July 23, 2004Publication date: January 26, 2006Inventors: Michael Betz, Stephen Garnett, Chih Liang, Michael Cronin
