The method may also include determining a proposed injection gas from among the plurality of potential injection gases for the field operation that comprises the gas injection to be performed using a first wellbore in fluidic communication with a first subterranean formation, a second wellbore in fluidic communication with the first subterranean formation, a third wellbore in fluidic communication with a second subterranean formation, or any combination thereof.

Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.

Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: The present invention relates to an intelligent prognostics and health management system and method, the system comprises an analytic engine service manager module, an intelligent prognostics and health management object analytics tree module, a machine learning library module, and a file system module. After the analytic engine service manager module defines an analytics tree according to components of a to-be-monitored machine, the intelligent prognostics and health management object analytics tree module is controlled by the analytic engine service manager module to obtain monitoring data of the to-be-monitored machine. One of default reference hypothesis model sets with the highest similarity of the system is selected for modeling, thereby a model selection and disposition are quickly complete.

Abstract: The present invention provides a modeling method for a smart prognostics and health management system. The method comprises a new tree establishing step, a dual-branch modeling step, and a model adaptive optimization step. As monitoring data increases, a golden model can be selected as a benchmark for optimization decision from prediction hypothesis models constructed by the dual-branch modeling step. This benchmark is used for next prediction. A prediction result of the system is caused to meet an expected target value. The present invention provides a computer program product for the smart prognostics and health management system at the same time. The above-described modeling method for the smart prognostics and health management system is completed when the computer program product is executed.

Abstract: A conductive path, such as a copper patch, between decoupling capacitors and a high frequency integrated circuit, may be oxidized to improve the power delivery performance. Specifically, adding the resistance in the conductive path by oxidizing the conductive path increases the dampening of the peak impedance at a given peak frequency. In some embodiments, a mask may be used to control the amount of the conductive path that is oxidized.

Abstract: A quick assembling nut of present invention comprising: a main part provides with a penetrating hole. There are two pivot seats on the wall of the penetrating hole. Two swing arms pivot on the pivot seat. One end of the swing arm bends to one side to form an against portion. The other end of the swing arm provides a grip portion. The grip portion has an arc wall with threads thereon. Those two arc wall are placed face to face and then those two against portions bend outward of the main part. Two elastic members are placed individually in the pivot seat and between the swing arm and the main part for providing a tension to keep those two against portions stay away from the pivot seat.

Abstract: Intramuscular stimulation (IMS) pain relief therapy is facilitated by a hand-held tool which, once positioned against a patient's skin, can be controlled to automatically advance a needle to penetrate the patient's flesh, reciprocate the needle within the patient's flesh a predetermined number of times through a predetermined stroke, and retract the needle. A tubular guide member is provided at its distal end with a skin contact member forming a constricted orifice closely matching the diameter of the needle. The orifice allows substantially free passage of the needle therethrough and at the same time prevents bowing of the needle as it is advanced--a primary source of patient pain. Automation and control of the needle penetration, reciprocation and retraction sequence reduces the amount of manual and mental effort required on the part of the treating physician, thereby allowing physicians to perform IMS procedures more consistently, effectively and efficiently.
