  • Publication number: 20240273358
    Abstract: Predicting the storage capacities of water reservoirs is an important planning activity for effective conservation and water release practices. However, current state-of-the-art solutions are not generalizable to all water reservoirs. Accordingly, disclosed embodiments train a machine-learning model using a training dataset that comprises labeled feature vectors that each includes a time series of tuples and is labeled with the target value of at least one storage parameter for a water reservoir. Each tuple may comprise climate parameter(s), such as temperature, precipitation, and/or soil moisture, for the watershed of the water reservoir, and/or reservoir parameter(s), such as water level, water storage, storage capacity, water inflow, and/or water outflow of the water reservoir. The machine-learning model may be a recurrent neural network with long short-term memory, that is trained to predict the value of the storage parameter at least seven days into the future.

  • Publication number: 20230262630
    Abstract: Clock synchronization, including: receiving a first message at an uncorrected unit with a propagation delay time, wherein a transmission time of the first message is recorded by a corrected unit; recording an arrival time of the first message by the uncorrected unit; transmitting a second message from the uncorrected unit to the corrected unit after a pre-determined delay, receiving a third message at the uncorrected unit, wherein the third message includes a propagation delay time and the transmission time of the first message recorded by the corrected unit; calculating a clock offset between the corrected unit and the uncorrected unit using the propagation delay time and the transmission time of the first message recorded by the corrected unit; and applying the clock offset to synchronize a clock of the uncorrected unit to a clock of the corrected unit.

  • Patent number: 9486140
    Abstract: A motion sensor applicable to medical procedures includes a source of light with a wavelength bandwidth and an optical detector. A first optical coupler terminates in a first probe tip and couples the light into the first probe tip. A second optical coupler terminates in a second probe tip and directs onto the detector scattered light returning through the second probe tip. A presentation device outputs a signal that indicates motion in a target volume of a sample in a vicinity of the probe tips based on a Doppler shift of the scattered light. The volume depends on coherence distance determined by the bandwidth. In variations, the first and second tips are the same tip, a multimode fiber is included, the bandwidth is between 0.1% and 5% of a center wavelength, or the presentation device is a speaker, or some combination.
