Abstract: Integrated circuit structures having source or drain structures with vertical trenches are described. In an example, an integrated circuit structure includes a fin having a lower fin portion and an upper fin portion. A gate stack is over the upper fin portion of the fin, the gate stack having a first side opposite a second side. A first source or drain structure includes an epitaxial structure embedded in the fin at the first side of the gate stack. A second source or drain structure includes an epitaxial structure embedded in the fin at the second side of the gate stack. The epitaxial structures of the first and second source or drain structures have a vertical trench centered therein. The first and second source or drain structures include silicon and a Group V dopant impurity.

Abstract: A thermal management system includes a baseplate assembly and a flow system. The baseplate assembly includes a baseplate and a semiconductor die. The flow system includes a submerged jet impingement assembly for direct semiconductor die cooling, a first flow path extending over the semiconductor die via the submerged jet impingement assembly, and a second flow path in thermal contact with the baseplate, the flow system including a fluid flowing through the first flow path and the second flow path. The flow system is configured to direct the fluid to the upper semiconductor surface of the semiconductor die via the first flow path and to the baseplate via the second flow path so as to transfer heat away from the semiconductor die and from the baseplate so as to cool the baseplate assembly.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: The present disclosure provides an electrical motor configured to operate with conductive fluids internal to the motor without short-circuiting. One embodiment is a telemetry modulator that can include the electric motor and a valve coupled with the electric motor. The valve has a valve stator and a valve rotor, and the electric motor can be used to control accurately the valve opening and closing with valve rotor rotation. The valve rotor can rotate continuously or in oscillations to generate a continuous pressure wave, such as for MWD/LWD communication. The electric motor is configured to allow drilling mud to flow into the electric motor without short-circuiting by the motor stator and/or motor rotor having an electric motor winding and a termination for the winding, the winding and termination having a nonconductive coating. The electric motor can be used in other applications inside and outside the oil field environment.

Abstract: A system monitors temperature and vibration of one or more conduits that are part of a fluid flow path or paths of heat transfer equipment to detect potential fouling or other maintenance issues within the fluid flow path(s).

Abstract: A system for detecting characteristics of a fluid includes a sonic sensor. The sonic sensor includes a transducer, a transduction surface, and an acoustically reflective pad member. The transducer may be contained within a probe body, and the transduction surface may be an element of the probe body. A stem may connect the pad member to the transduction surface. The transducer will generate pulses that are transmitted to the pad member via a fluid when the transduction surface and pad member are immersed in the fluid. The system will detect the pulses when reflected and use that data to determine a speed of sound within the fluid. The system may use the speed of sound to determine density, specific gravity and/or stiffness of the fluid. The system may use that determination to assess a level of processing activity of the fluid, such as fermentation activity.

Abstract: Systems and methods for monitoring a cheesemaking process, and for identifying certain stages of the process, are disclosed. The system includes a sonic sensor, along with a processor that will receive, from the sonic sensor, a signal that is indicative of a speed of sound in a material that is being processed in the cheesemaking process. The processor will use the speed of sound to identify a cut point in the cheesemaking process. The processor will generate a signal when the cut point is reached. Optionally, before this happens the processor also may use the speed of sound to identify a flocculation point in the cheesemaking process.

Abstract: The present disclosure provides a bearing design that accommodates misalignment of a rotatable shaft in the bearing and is well suited to usage in a particulate-laden fluid. The bearing can be shaped with a curved surface along a longitudinal axis of the bearing, such as in a curved barrel shape or a ball shape, to provide a point contact instead of a line contact as is the case with conventional plain bearings. The point contact allows the bearing to adjust with a misalignment between ends of the shaft or between the external supports and facilitates the assembly and disassembly of the rotating shaft. Because the bearing compensates for misalignment, the bearing surfaces can have closer tolerances for a smaller gap between the bearing surfaces, which can result in improved performance.

Abstract: A system for monitoring processing of a fluid receives one or more characteristics of the fluid and uses those characteristics to determine specific gravity of the fluid and a level of processing activity of the fluid. The processor will cause a display device to output a dynamic representation of the specific gravity of the fluid as well as the determined level of processing activity. In some embodiments, the processing activity may include fermentation, as that of a beverage. If so, the dynamic representation of the determined level of processing activity may include a fermentation tank with a dynamically changing cavity. Displayed characteristics of the cavity will change as the determined level of the fermentation increases.
