Abstract: A method is provided for reconstructing a high dynamic range (HDR) video from a low dynamic range (LDR) video. The LDR video is captured with dynamic exposure values by a regular camera device to store as an LDR video file. An exposure setting sequence and an LDR video frame sequence are retrieved from the LDR video file, where the exposure setting sequence corresponds to the LDR video frame sequence. The LDR video frame sequence is aligned to generate a compensated frame sequence to merge with the LDR video frame sequence, so as to generate an HDR frame sequence and reconstruct the HDR video.

Abstract: The present invention relates to an infant body temperature and sleep monitoring system including a Bluetooth body temperature thermometer main body, an arm belt and a Bluetooth receiving member; the Bluetooth body temperature thermometer main body is connected to a first side of the arm belt via a first adhesive strap; a second side of the arm belt is disposed with a fastening ring at a first end and a second adhesive strap at a second end; the second end of the arm belt which is disposed with the second adhesive strap passes through the fastening ring and engages with the second adhesive strap so that the arm belt forms a tightness-adjustable annular belt; the Bluetooth body temperature thermometer main body obtains body temperature data and transmits the body temperature data to the Bluetooth receiving member. The present invention is simple in structure, convenient and practical and easy to wear.

Abstract: According to one aspect of the invention, for a database statement that specifies rollup operations, a data distribution key may be selected among a plurality of candidate keys. Numbers of distinct values of the candidate keys may be monitored with respect to a particular set of rows. Hash values may also be generated by column values in the candidate keys. The data distribution key may be determined based on results of monitoring the numbers of distinct values of the candidate keys as well as the frequencies of hash values computed based on column values of the candidate keys. Rollup operations may be shared between different stages of parallel executing processes and data may be distributed between the different stages of parallel executing processes based on the selected data distribution key.

Abstract: A radio frequency communication system, method, and device operate in the VHF, UHF, or SHF range, where a controller controls the radio-frequency communication range provided by the VHF, UHF, or SHF radiation.
