摘要: 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.

摘要: A system and method of determining three-dimensional coordinates is provided. The method includes, with a projector, projecting onto an object a projection pattern that includes collection of object spots. With a first camera, a first image is captured that includes first-image spots. With a second camera, a second image is captured that includes second-image spots. Each first-image spot is divided into first-image spot rows. Each second-image spot is divided into second-image spot rows. Central values are determined for each first-image and second-image spot row. A correspondence is determined among first-image and second-image spot rows, the corresponding first-image and second-image spot rows being a spot-row image pair. Tach spot-row image pair having a corresponding object spot row on the object. Three-dimensional (3D) coordinates of each object spot row are determined on the central values of the corresponding spot-row image pairs. The 3D coordinates of the object spot rows are stored.
