  • Publication number: 20190193988
    Abstract: The present invention relates to automatic elevator call control, and belongs to the field of elevator intelligent control technologies. An automatic elevator call system provided in the present invention calculates duration information from the moment when the personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again, and when the duration information is less than or equal to a preset time threshold, causes the personal mobile terminal to be incapable of automatically sending an elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again. The present invention can effectively avoid invalid or abnormal elevator call request operations, and the elevator system achieves high running efficiency.

  • Patent number: 10007451
    Abstract: Methods of sudden power off recovery may include reading dirty-block meta-pages from memory blocks on a dirty block list, recording mapping in formation in open-block meta-pages, serving host commands by looking up logical block addresses (LBAs) in the dirty-block meta-pages and the open-block meta-pages and when an LBA is not found in the dirty-block meta-pages and the open-block meta-pages, reading new mapping information from a dirty table and saving the new mapping information in host-write meta-pages.

  • Publication number: 20170035291
    Abstract: The subject invention provides novel apparatuses and methods for assessing the structure and function of photoreceptors in retina. In a specific embodiment, the assessment is accomplished by imaging rhodopsin, pigmented protein responsible for initiating vision acquisition of the eye, in living subjects. Advantageously, the technologies provided herein can be used for clinical evaluation of retinal photoreceptors for diagnosis, disease staging and follow-up, and outcome measurement for clinical trials of retinal degenerative disorders, including, for example, hereditary retinal degeneration and age-related macular degeneration.

  • Patent number: 8786873
    Abstract: Systems and methods are disclosed for managing autonomous detector and imager subsystems communicating as nodes on a network. In an embodiment, an application server is provided which coordinates use of the autonomous imager and detector subsystems so that appropriate combinations of imagers and detectors are used for particular imaging applications. In another embodiment, the performance of a detector subsystem may be automatically evaluated prior to use, such as by one or more automated routines that monitor or measure factors related to detector performance. Additional systems, methods, and devices are also disclosed.

  • Publication number: 20130034213
    Abstract: A digital X-ray detector includes a shock monitoring system configured to monitor for an occurrence of a shock event via at least one shock sensor. The detector also includes a processor configured to receive information related to the shock event from the shock monitoring system and to report the shock event to an X-ray system communicatively coupled to the detector.

  • Patent number: 4770067
    Abstract: A method of manufacturing a surgical cutting blade having a heating element mounted on the sides thereof which is capable of supplying sufficient thermal energy to cauterize incised tissue and reduce hermorraging of blood vessels at the site of the incision. According to the method, a thermally conductive hardened metallic cutting blade, having a thermal conductivity coefficient of at least 0.6, preferably at least 0.8, which is sufficient to transmit a cauterizing thermal flux from the heating element to the cutting edge at a heating element temperature which does not burn tissue adjacent to the heating element during the incision, is provided with a layer of dielectric insulation adhered directly to the surface of the blade. A heating element pattern is directly adhered to the dielectric insulation layer.

  • Patent number: 4357175
    Abstract: An environmentally acceptable method for cleaning the interior of vessels comprises contacting the interior of a vessel with a solvent for the contaminant contained therein to produce a contaminated solvent, collecting the contaminated solvent from the vessel, separating essentially all of the contaminant from the contaminated solvent to recover essentially all of the solvent essentially free of the contaminant and produce a contaminant composition which is incineratable or can be made incineratable by blending with a combustible composition, such as fuel oil.The contaminant may be separated from the contaminated solvent by distillation; in which case the overhead product may be washed with sulfuric acid and then neutralized with a base.
