  • Patent number: 11296271
    Abstract: The present disclosure is directed to materials, devices, and methods for resonant ambient thermal energy harvesting. Thermal energy can be harvested using thermoelectric resonators that capture and store ambient thermal fluctuations and convert the fluctuations to energy. The thermal resonators can include heat engines disposed between masses of varying sizes or diodes. The masses or diodes can be made of high and ultra-high effusivity materials to transfer thermal energy through the resonator and optimize power output. The masses or diodes of the resonator can be tuned to the dominant frequency of the temperature waveform to maximize the amount of energy being converted. The resonators can be added to existing structures to supply or generate power, and, in some embodiments, the structures themselves can be a mass of the thermal resonator. Methods for constructing and/or using such devices are also provided, as are methods for formulating ultra-high effusivity materials.

  • Publication number: 20220101513
    Abstract: The present disclosure provides a method for automatically identifying a ring joint of a shield tunnel based on a lining structure. The method includes the following steps: S1: acquiring a three-dimensional (3D) point cloud of a shield tunnel through a mobile scanning system: S2: generating an orthographic projection image of an inner wall of the tunnel: S3: identifving a feature of a bolt hole; S4: extracting a longitudinal joint of the shield tunnel: S5: generating a prior structural template ring; and S6: extracting a transverse joint of the shield tunnel. The present disclosure has the following advantages. Starting from the features of the lining structure of the shield tunnel, the present disclosure selects a bolt hole with a strong structural feature, takes the structural feature of the bolt hole as an identification feature, and indirectly extracts joint information of straight and staggered joints tunnel.

  • Publication number: 20200028053
    Abstract: The present disclosure is directed to materials, devices, and methods for resonant ambient thermal energy harvesting. Thermal energy can be harvested using thermoelectric resonators that capture and store ambient thermal fluctuations and convert the fluctuations to energy. The resonators can include non-linear heat transfer elements, such as thermal diodes, to enhance their performance. Incorporation of thermal diodes can allow for a dynamic rectification of temperature fluctuations into a single polarity temperature difference across a heat engine for power extraction, as compared to the dual polarity nature of the output voltage of linear thermal resonators, which typically necessitates electrical rectification to be routed to an entity for energy storage. In some embodiments, the thermal diode can be applied to transient energy harvesting to construct thermal diode bridges. Methods for constructing such devices, and using such devices, are also provided.
