Abstract: Techniques to provide a low-power single-photon avalanche diode (SPAD) image. An example imaging device includes a SPAD array having a plurality of pixels configured to detect electromagnetic radiation, and a processing device configured to deactivate, based on an event count, a pixel of the SPAD array for a remaining duration of a first detection frame of the SPAD array. The pixel can remain deactivated for the remaining duration, and the remaining duration can span from a deactivation time until an end of the first SPAD frame. The processing device can be further configured to reactivate the pixel in a subsequent detection frame of the SPAD array.

Abstract: The disclosure relates to methods for identifying desirable (e.g., the best) depth intervals in a reservoir using carbon isotope ratio information. The desirable depth intervals in the reservoir correspond to regions in the reservoir with source rocks and where natural gas is stored.

Abstract: The disclosure relates to methods for identifying desirable (e.g., the best) depth intervals in a formation using carbon and/or oxygen isotope ratio information. The desirable depth. intervals in the formation correspond to regions in the formation with source rocks and relatively high (e.g., the highest) total organic carbon (TOC).

Abstract: A product index mechanism for a product inspection system includes a material strip driving wheel and an index structure driving wheel. The material strip driving wheel engages with a material strip carrying a plurality of products to be inspected by an inspection device of the product inspection system. The driving wheel drives the material strip to move. The index structure driving wheel rotates synchronously with the material strip driving wheel and includes a plurality of product index structures thereon. As a product on the material strip is moved by the material strip driving wheel to an inspection position of the inspection device, one product index structure on the index structure driving wheel is rotated to a trigger position corresponding to a trigger of the inspection system. Activation of the trigger transmits a trigger signal to the inspection device to inspect the product.

Abstract: A computer receives a measured wetness of and a measured ?2H value associated with a test gas sample from a hydrocarbon formation. The measured wetness is a molar ratio of heavy gas compounds over a total gas within the measured sample. The computer receives calculated wetnesses calculated ?2H values associated with a gas samples taken from one or more analogous hydrocarbon reservoirs. The measured wetness received for the test gas sample is identified from among the plurality of calculated wetnesses. The computer determines a corresponding ?2H value from among the calculated ?2H values that corresponds to the measured wetness of the test gas sample. The computer determines a predicted sample VRo (vitrinite reflectance equivalent) for the test gas sample based on the corresponding ?2H value and a correlation of ?2H values to VRo values. Hydrocarbons are produced from the hydrocarbon formation based on the predicted sample VRo.

Abstract: The invention discloses an electric defroster, comprising a housing with a handle; a working wheel rotatably connected with housing and at least partially protrudes out of the surface of the housing, scraping pieces extending along the axial direction is arranged on the surface of the working wheel, and a power mechanism used for driving the working wheel to rotate relative to the housing; scraping pieces rotate in the circumferential direction to scrape ice. The invention utilizes the working wheel to roll and deice the glass surface, the flexibility of the position for scraping ice is higher and ice at the corner can be effectively scraped; there are more contact surface can be selected, ice scraping more flexible; scraped ice is quickly discharged from space between adjacent scraping pieces, ensuring ice scraping efficiency; the invention can not only be used for scraping ice, but also for cleaning and removing rust.
