  • Patent number: 12025573
    Abstract: The present disclosure provides systems, apparatuses, and methods for measuring submerged surfaces. Embodiments include a measurement apparatus including a main frame, a source positioned outside a pipe and connected to the main frame, and a detector positioned outside the pipe at a location diametrically opposite the source and connected to the main frame. The source may transmit a first amount of radiation. The detector may receive a second amount of radiation, determine a composition of the pipe based on the first and second amounts of radiation, and send at least one measurement signal. A control canister positioned on the main frame or on a remotely operated vehicle (ROV) attached to the apparatus may receive the at least one measurement signal from the detector and convey the at least one measurement signal to software located topside.

  • Patent number: 12016321
    Abstract: A discrete and safe automated insect monitoring system includes a housing, an interior chamber within the housing, and a light source arranged within the housing to illuminate at least a portion of a floor surface of the interior chamber. A multi-pixel optical sensor is arranged within the housing so that a field of view of the sensor comprehends a substantial portion of the floor surface. A processing circuit arranged within the housing receives optical data from the multi-pixel optical sensor, analyzes the optical data to detect the intrusion of an insect or other object into the interior chamber by comparing most recently received optical data to previously received optical data, and generates an indication in response to detecting the intrusion of an insect or other object. Detection and/or classification results can be wirelessly forwarded to another device, to alert appropriate personnel.

  • Patent number: 12021465
    Abstract: The present disclosure provides a DC motor driving system including a DC motor, a power supply device, a switch circuit, and a microprocessor. The power supply device provides an input electrical energy. The switch circuit receives the input electrical energy and outputs a motor electrical energy, which includes a motor power and a motor voltage, to the DC motor. The DC motor driving system switchably works in a constant-voltage mode, a first variable-voltage mode, or a second variable-voltage mode. In the constant-voltage mode, the input electrical energy remains unchanged. In the first variable-voltage mode, the microprocessor controls the power supply device to adjust the input electrical energy for increasing the motor voltage and the motor power. In the second variable-voltage mode, the microprocessor controls the power supply device to adjust the input electrical energy for decreasing the motor voltage and keeping the motor power unchanged.
