Abstract: In an embodiment based on computer(s), an ML model is trained to detect outliers. The ML model calculates anomaly scores that include a respective anomaly score for each item in a validation dataset. The anomaly scores are automatically organized by sorting and/or clustering. Based on the organized anomaly scores, a separation is measured that indicates fitness of the ML model. In an embodiment, a computer performs two-clustering of anomaly scores into a first organization that consists of a first normal cluster of anomaly scores and a first anomaly cluster of anomaly scores. The computer performs three-clustering of the same anomaly scores into a second organization that consists of a second normal cluster of anomaly scores, a second anomaly cluster of anomaly scores, and a middle cluster of anomaly scores. A distribution difference between the first organization and the second organization is measured. An ML model is processed based on the distribution difference.

Abstract: A method for manufacturing a tow hook assembly begins with heating a first steel blank to within a range of 2200° F. and 2300° F. to create a first heated steel blank. A second steel blank is heated to within the range of 2200° F. at 2300° F. to create a second heated steel blank. The first heated steel blank is forged into a tow hook. The second heated steel blank is forged into a flange plate. The tow hook in the flange plate are welded together to form the tow hook assembly. This method reduces waste by minimizing the size of the first and second steel blanks.

Abstract: A watercraft angle of attack system includes sensors having a position locator; a heading sensor; a tilt sensor; an acoustic Doppler velocity sensor that measures velocity of the boat relative to a volume of water remote from the boat so as to reduce the boat-induced disturbance of the velocity in the volume; and a processor programmed to receive real time data from the sensors; and to compute and display angle of attack of the watercraft relative to the water.

Abstract: One embodiment of the present invention provides a method that reduces power consumption by using capacitive coupling to perform a majority detection operation. The method involves driving a plurality of signals onto a plurality of driven wires. The signals are then fed from each driven wire through a corresponding coupling capacitor to a single majority detection wire. In addition, method involves feeding a signal on the majority detection wire and a bias voltage to a differential receiver. The output of the differential receiver switches if the signal on the majority-detection wire switches relative to the bias voltage. The method further involves using the output of the differential receiver to optimize the signals from the plurality of driven wires for transmission across a long signal route. Optimizing the transmission of signals reduces the power consumed by a computer system.

Abstract: An apparatus receives survey instructions from a directed unit and measurement data from a measurement unit. The apparatus directs a survey workflow comprising a plurality of stages, determines the completion of at least one of the stages based upon at least one of the measurement data and the survey instructions, provides workflow information, selects survey data from the measurement data, and stores the survey data in a memory. The apparatus sends the workflow information to the directed unit.

Abstract: An intramuscular stimulation (IMS) device and method permit electrical and mechanical modes of stimulation to be carried out individually or together. The gun-like stimulation device permits a disposable needle applicator unit including a needle and elongate sheath to be removably attached thereto. Different needle penetration depths are obtainable with a single needle by virtue of a drive carriage with a position selecting element. To help avoid repetitive strain injury to a treating physician, a processor may monitor a body contact sensor and continue an intramuscular stimulation cycle only so long as contact is detected. In order to ensure that only a single IMS operation is performed during a period of body contact, performance of a further intramuscular stimulation cycle may be prevented unless it is determined that body contact was broken at a time following a previous IMS cycle.

A shutter (16) is slidable to expose one or the other of the retrieval means. Movement of the shutter switches on the CPU which is dedicated to the exposed retrieval means.

Abstract: A rotational glider toy configured for producing bubbles during free flight. The toy includes a circular disc body having a plurality of bubble-forming apertures formed therein. A reservoir structure is coupled to a lower surface of the body and encloses a storage area. The reservoir structure includes a plurality of solution feed holes formed in a junction between the reservoir structure and the lower surface, said solution feed holes being in communication with the storage area. Bubble solution is inserted into the storage area through a capped filling hole therein. Centrifugal force during rotational movement of the toy operates to urge the bubble solution out of the feed holes such that it spreads onto the lower surface of the body and into the bubble-forming apertures. Air currents passing through the bubble-forming apertures cause the bubble solution to be released from the toy in a stream of bubbles.
