20080312655 | POLYAXIAL SCREW SYSTEM AND METHOD HAVING A HINGED RECEIVER - A polyaxial screw system and method are provided. The system comprises a receiver having a pivot area defined by a pivot joint or a material between a pair of receiver walls or members that permit the receiver walls or members to move or pivot relative to each other so that a dimension of a socket area can be changed. The socket area is defined by socket walls that when at least one of the receiver members pivots relative to another receiver member or wall, a distance between the socket walls gets smaller so that the socket walls can engage and lock against a head of a polyaxial screw. | 12-18-2008 |

20120128494 | VARIABLE PERFORMANCE VANEAXIAL FAN WITH HIGH EFFICIENCY - The design of a high efficiency, variable performance vaneaxial fan, requires the utilization of typical fan and single stage compressor design methodologies. To be able to replace multiple fans, the variable vaneaxial fan design must be capable of operation at several different flow rates and total pressures. These operation points can be met by varying motor revolutions per minute (RPM) or geometric parameters such as the hub diameter, tip diameter, as well as blade geometry including number of blades, pitch, spacing, and length. An ideal design with variable performance can replace a family of current fan designs by providing the capability for efficient operation over a range of flow rates and total pressures. This level of variability would not only allow the fan to respond to changing environmental conditions but also to be fit into systems with different characteristics. | 05-24-2012 |

20100119704 | COMPOSITE SELF-HEALING SYSTEM - An advanced reflexive structure system is disclosed. The reflexive system mimics the pain withdrawal reflex on which the human body relies. The reflexive system incorporates a continuous health and performance monitoring system via an embedded dielectric film, an adaptive composite structure based on shape memory composite material, and an intelligence system which will be interfaced with both the health/performance sensors and the adaptive structure. When activated shape memory polymer will recover its structural integrity via shape recovery and a reptation healing process. These features enable the use of SMP as an adaptive structure in the proposed reflexive system. The development of a reflexive system for structures will enable increased safety and security and demonstrate a better understanding of integrated performance systems. This reflexive technology could find immediate implementation on all current and future systems and future implementation on platforms such as the International Space Station, Lunar, and Martian habitats. | 05-13-2010 |

20140262134 | HVAC SYSTEM REMOTE MONITORING AND DIAGNOSIS - An apparatus for monitoring a heating, ventilation, or air conditioning (HVAC) system includes an indoor unit monitor module electrically connected to a current sensor and first and second refrigerant temperature sensors. The current sensor generates a first current signal based on aggregate current consumed by components of an indoor unit of the HVAC system. The refrigerant temperature sensors generate first and second refrigerant temperature signals, respectively, based on measured temperatures of refrigerant circulating within the HVAC system. The indoor unit monitor module receives, from a secondary monitoring module, a second current signal based on aggregate current consumed by components of an outdoor unit of the HVAC system. The indoor unit monitor module transmits data to a remote server to assess whether a failure has occurred or is likely to occur in the components of the HVAC system. The data is based on the current signals and the refrigerant temperature signals. | 09-18-2014 |

The monitoring server receives the transmitted current data and, based on the received current data, assesses whether failures have occurred in first and second components of the HVAC components. The monitoring server generates a first advisory in response to determining that the failure has occurred in the first component. The review server provides the first advisory to a technician for review and, in response to the technician verifying that the failure has occurred, transmits a first alert. | 09-18-2014 |
