  • Patent number: 12215304
    Abstract: An integrated facility for the co-production of ethanol and the pretreatment of impure vegetable oils, waxes and (animal) fats is provided. A by-product from the ethanol plant, such as distillers corn oil or distillers sorghum oil, can be directly refined on site to remove contaminants such as metals, phospholipids and inorganic anions, to enable use as ready feedstocks for a renewable diesel hydrotreatment plant. The utility of the ethanol plant infrastructure can be directly harnessed to pretreat and purify a variety of impure feedstock materials. The pretreatment reduces catalytic poisoning in the reduction process at refining facilities during the synthesis of renewable diesel. By-products of the pretreatment process are recycled to various parts of the ethanol plant for incorporation into the animal feed(s) produced by the ethanol plant or incorporated into the existing wastewater treatment and disposal system within the ethanol plant.

  • Patent number: 12214208
    Abstract: An intracardiac ventricular pacemaker is configured to detect a ventricular diastolic event from a motion signal received by a pacemaker control circuit from a motion sensor. The control circuit starts an atrial refractory period having an expiration time set based on a time of the detection of the ventricular diastolic event. The control circuit detects an atrial systolic event from the motion signal after expiration of the atrial refractory period and controls a pulse generator of the pacemaker to deliver a pacing pulse to a ventricle of a patient's heart at a first atrioventricular pacing time interval after the atrial systolic event detection.

  • Patent number: 12216312
    Abstract: An optical input polarization management device includes a polarization splitter and rotator (PSR) that directs a portion of incoming light having a first polarization through a first optical waveguide (OW). The PSR rotates a portion of the incoming light having a second polarization to the first polarization so as to provide polarization-rotated light. The PSR directs the polarization-rotated light through a second OW. Light within the first and second OW's is input to a first two-by-two optical splitter (2×2OS). A first phase shifter (PS) is interfaced with either the first or second OW. Light is output from the first 2×2OS into a third OW and a fourth OW. Light within the third and fourth OW's is input to a second 2×2OS. A second PS is interfaced with either the third or fourth OW. Light is output from the second 2×2OS into a fifth OW for further processing.

  • Patent number: 12217439
    Abstract: Optical flow refers to the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. Optical flow algorithms can be used to detect and delineate independently moving objects, even in the presence of camera motion. The present invention uses optical-flow algorithms to detect and remove marine snow particles from live video. Portions of an image scene which are identified as marine snow are reconstructed in a manner intended to reveal underwater scenery which had been occluded by the marine snow. Pixel locations within the regions of marine snow are replaced with new pixel values that are determined based on either historical data for each pixel or a mathematical operation, such as one which uses data from neighboring pixels.
