  • Patent number: 11925441
    Abstract: Methods, systems, and devices for determining blood pressure based on morphological features of pulses are described. A system may include a wearable device that uses one or more light emitting components configured to emit light, one or more photodetectors configured to receive light, and a controller that couples the one or more light emitting components to the one or more photodetectors. The wearable device may transmit lights associated with multiple wavelengths, and acquire photoplethysmogram (PPG) data that includes one or more PPG waveforms associated with the respective wavelengths. The system may determine respective sets of morphological features associated with each of the PPG waveforms based on systolic and diastolic peaks corresponding to the heartbeat of the user. The system may determine one or more blood pressure metrics for the user based at least in part on a comparison of the respective sets of morphological features.

  • Patent number: 10730056
    Abstract: A mineral material processing plant and a method for controlling thereof. The processing plant includes at least one motor, at least one actuator, a control and adjusting system, a switch for switching the processing plant to a standby mode and an arrangement for keeping selected actuators in operation with a reduced standby speed. In the method, a command is given to the processing plant to switch to the standby mode and in response to the command to switch to the standby mode, feeding of mineral material to the processing plant is limited and speed of the motor or motors of the processing plant is reduced from the processing speed (Rf) to a reduced standby speed (Rsb) and it is ensured that selected actuators of the processing plant remain operating with a reduced speed.

  • Patent number: 9993827
    Abstract: A mineral material processing plant and a method for controlling thereof. The mineral material processing plant includes at least one motor, at least one actuator, a feeder device, a control system, and an arrangement for recognizing a need to switch off a standby-mode. The control system is configured to control the processing plant in such a way that the need to switch off a standby mode is automatically recognized. In response to the recognized need to switch off the standby mode the running speed of a motor or motors of the mineral material processing plant is raised from a stand-by speed (Rsb) to a process speed (Rf); and the feeding of mineral material into the processing plant is enabled.
