20110316691 | FLAT-HIERARCHY SYSTEM FOR CONDITION-BASED MONITORING OF DISTRIBUTED EQUIPMENT - Systems and methods for monitoring the condition of equipment in a manufacturing plant or other facility. A computing node is attached to each piece of equipment under consideration. Each node gathers relevant information from the machine using sensors and is capable of determining the condition of the machine from a preexisting set of possible conditions, using only the information obtained from the sensors. Each node is thus entirely self-sufficient, in that it requires no interaction with a global controller or with other nodes in order to make a decision about the condition of the equipment, and does not necessarily require any information about the past history of the equipment. The nodes are capable of communicating the condition of their corresponding equipment to key maintenance or other personnel, potentially via a wireless network to a convenient wireless-capable device such as a cellular phone or laptop. | 12-29-2011 |

20130000980 | System and Method for Determining Soil Characteristics and Drillstring Instability During Horizontal Directional Drilling - Disclosed is a system and method for horizontal directional drilling (HDD). The system and method utilize predictive algorithms to both characterize the soil within the borehole and to quantify instability within the drillstring. The soil characteristics are represented by a soil coefficient (α), which relates the curvature of the borehole with the length of thrust of the drill rig as well as by comparison of thrust while thrusting with torque while drilling. The value of (α) is obtained by comparison of the historical orientation of the drilling head over the length of the borehole and the borehole shape as determined by an arbitrary navigation sensor. Drillstring instability is determined as a function of historical thrust and torque efficiencies and windup over the length of the borehole. | 01-03-2013 |

20140359127 | ZERO TOUCH DEPLOYMENT OF PRIVATE CLOUD INFRASTRUCTURE - Automatically provisioning computing resources based on events occurring in the computer network. The system manager defines resource configurations for computing resources in a network computing environment. The resource configurations are associated with event conditions. The event conditions cause the system manager to apply the resource configurations to the computing resources. The event conditions are also associated with various policies. The policies specify how the resource configurations are to be applied to the computing resources. The occurrence of the event conditions is ascertained. In response, workflows are automatically executed. The workflows apply the resource configurations to the computing resources in accordance with the policies. This configures the computing resources according to the resource configurations. | 12-04-2014 |
