  • Patent number: 10692601
    Abstract: In some examples, a computing device may receive hierarchical data having a hierarchical structure including a plurality of levels. The computing device may determine a plurality of features based at least in part on the hierarchical data, and may select a subset of the features at a first level as candidates for consolidating to a next higher level in the hierarchical structure. The computing device may determine that a predicted loss of information from consolidating the subset of features is less than a threshold, and may revise the hierarchical structure to include a consolidated feature at the next higher level, rather than the subset of features. In some examples, a statistical model may be trained based on the revised hierarchical structure and used at least partially to make a determination, send a notification, and/or control a device.

  • Patent number: 10662866
    Abstract: A diesel engine includes a cylinder head, a cylinder sleeve, a piston, an injector, and a combustion chamber. The top side of the piston includes an annular top surface, an annular collision belt and an annular cavity. The collision belt includes a collision surface, an upper guide surface, and a lower guide surface. An annular throat is formed between the upper guide surface and the cylinder head. The collision belt divides the combustion chamber into a headspace and a central portion. The volume of the headspace is more than three times of the volume of the central portion. A major portion of the fuel jet injected by the injector is directed into the headspace. The results are faster mixing of fuel and air and complete combustion in the combustion chamber, and a reduction of fuel consumption rate by 2%. A method for fuel distribution and combustion is also disclosed.

  • Publication number: 20120021689
    Abstract: A signaling method for mitigating interference by a device in a machine-to-machine (M2M) communication system. The device measures reference signals transmitted from other devices, and determines a Neighbor Device Set (NDS) including at least one device whose signal power is greater than or equal to a first threshold. Based on the measured values of the reference signals, the device sets up M2M communication with a first device, for data communication, and determines a Restricted Device List (RDL) including at least one device causing interference unallowable for communication with the first device based on the measured value of the reference signal from at least one device in the NDS. The device also transmits the RDL to at least one device in the NDS or the RDL, thereby mitigating the overall system interference.
