20160137188 | Control systems and methods for transmission of hybrid power vehicle - A transmission control system for a hybrid-power driving system includes at least a gear shifting actuation module to control engagement of specific gearwheels and a clutch actuation module to control a clutch that couples an engine to the transmission. Gear shifts are required for each of the engine and the electric motor in the hybrid-power driving system. The control system minimizes power loss when a gear shift is occurring for the engine or the electric motor. By selectively controlling the clutch and engagement of specific gearwheels, power loss associated with a gear shift for one of these power sources can be directly offset by using the other power source. | 05-19-2016 |

Gear shifts are required for each of the engine and the electric motor in the hybrid-power driving system. By selectively controlling the clutch and engagement of specific gearwheels, the transmission control system can start the engine when the vehicle is initially powered by the electric motor alone. Starting the internal combustion engine in this case switches the vehicle from a pure motor driving mode to a hybrid driving mode. Additionally, the transmission control system can start the engine when the vehicle is in a parked state, for example, to put the vehicle in a battery charging mode for the electric motor. | 05-19-2016 |

20120128566 | METHOD FOR PRODUCING FLUORAPATITE AND ITS APPLICATION - A method for producing fluorapatite and its application are disclosed in the present invention, which relates to the field of biomaterials for dental reparation. The present invention comprises steps of mixing tetracalcium phosphate, calcium hydrogen phosphate, and sodium fluoride to form a mixture and adding the mixture into water, or mixing tetracalcium phosphate and ammonium fluoride to form a mixture and then adding the mixture into a phosphoric acid/water solution, blending the above two sets of materials respectively to form cement-like substances; and solidifying the cement-like substances at a temperatures of 35° C. to 38° C. and a moisture of 100% for 1-3 days to produce fluorapatite. The synthesized fluorapatite has a similar chemical composition with tooth enamel, thus, the fluorapatite produced by the invention can be combined with the natural enamel directly, so as to repair enamel defects caused by caries, especially severe enamel defects (deep caries). The synthesized fluorapatite has a stoichiometric amount of apatite structure, and has high chemical stability (low solubility) in a physiological condition of human body fluid. In acidic conditions (when bacteria exist) the fluorapatite releases fluorine ion slowly, so it further has an ability to prevent dental caries. | 05-24-2012 |

20140373603 | Reducing False Alarms with Multi-modal Sensing for Pipeline Blockage - A detection system and method of operation are disclosed. The system includes a first sensor coupled to a pipe associated with a pump and generates temperature data associated with a temperature of the pipe. The system includes a second sensor positioned within an acoustic sensing distance from the pump and that generates sound data associated with a sound of the pump. The system includes a processing device configured to execute data instructions to store a baseline temperature signature and a baseline acoustic signature, and receive the temperature data from the first sensor and the sound data from the second sensor. The processing device is configured to, based on (1) a determination that flow through the pipe is reduced by comparing temperature data to the baseline temperature signature, and (2) a determination that the pump remains operational based on comparing the acoustic data to the baseline acoustic signature, generate an indication that the pipe is blocked. | 12-25-2014 |
