Abstract: Systems and techniques for determining degree of motion using machine learning to improve medical image quality are presented. In one example, a system generates, based on a convolutional neural network, motion probability data indicative of a probability distribution of a degree of motion for medical imaging data generated by a medical imaging device. The system also determines motion score data for the medical imaging data based on the motion probability data.

Abstract: Systems and techniques for generating and/or employing a computed tomography (CT) medical imaging fracture model are presented. In one example, a system employs a first convolutional neural network associated with vertebrae segmentation to generate learned vertebrae segmentation data regarding a spine anatomical region related to a CT image. The system also employs a second convolutional neural network associated with fracture segmentation to generate, based on the learned vertebrae segmentation data, learned fracture segmentation data regarding the spine anatomical region. Furthermore, the system detects presence or absence of a medical fracture condition in the CT image based on the learned vertebrae segmentation data and the learned fracture segmentation data.

Abstract: A torque vectoring differential constructed in accordance to the present disclosure includes a differential carrier rotatable about an axis. A pinion carrier can have at least one pinion gear mounted for rotation on at least a portion of the pinion carrier. First and second side gears can be meshed for engagement with at least one pinion gear. The first side gear can be engaged for rotation with a first axle shaft. The second side gear can be engaged for rotation with a second axle shaft. A first clutch can be operable to selectively lock the differential carrier and the pinion carrier with respect to one another for rotation about the axis. A second clutch can be operable to selectively lock the differential carrier to the first side gear. A third clutch can be operable to selectively lock the differential carrier to the second side gear.

The means for attaching is sized and otherwise dimensioned to be fixedly received in the at least one receiving terminal.

Abstract: Methods and devices for eliminating a systematic imbalance and reducing variations in circuit parameters for a high gain amplifies. A bias generator having a copy of an actual amplifier branch and an already generated bias voltage can be added to the amplifier to generate a bias voltage for a final current source at a current summing node so as to eliminate systematic imbalance in the bias current. A high impedance node can be wired in the bias generator such that all devices in the bias generator are in saturation across, for example, PVT (Process, Voltage and Temperature) corners in order to minimize tracking errors. A degeneration transistor similar to a differential pair element can be split into two equal halves.

Abstract: A Rankine cycle system including a Rankine cycle working circuit and a lubrication circuit is disclosed. The lubrication circuit and the Rankine cycle working circuit include a shared segment including a mixture of Rankine cycle working fluid from the Rankine cycle working circuit and lubricant from the lubrication circuit. A separator receives the mixture of Rankine cycle working fluid and lubricant from the shared segment and separates the Rankine cycle working fluid from the lubricant. The separated Rankine cycle working fluid is directed along the Rankine cycle working circuit from the separator to the heating zone and the separated lubricant is directed along the lubrication circuit from the separator to a mechanical expander. The working fluid and lubricant are recombined after passing separately through the expander and are then introduced to the condensing zone.

Abstract: An electroplating system and components thereof facilitate an efficient electroplating process which in part reduces or eliminates the number of clips used on electroplating racks. Some electroplating racks may use skewers on which multiple plastic pieces are typically mounted. The plastic pieces may also be configured to be joined to form an assembly which is mounted on an electroplating rack. The configurations help reduce the time spent loading and unloading pieces on the racks.

Abstract: A USB transceiver has transmitter circuitry, receiver circuitry, short-circuit detection circuitry, and short-circuit protection circuitry. The transmitter circuitry transmits a differential pair of outgoing data signals to a cable connected to the transceiver, and the receiver circuitry receives the differential pair of outgoing data signals via bi-directional input-output pins. The short-circuit detection circuitry analyzes each of the outgoing differential data signals to detect a short circuit in the pair of outgoing data signals, and the short-circuit protection circuitry protects the transmitter circuitry upon detection of a short circuit.
