摘要： A brazed X-ray target includes a metallic cap and a graphite back including a nonlinear record groove attached thereto along a stepped surface. An upper corner joint of the stepped surface is distanced from a cap outer edge and a focal track where the maximum heat is generated during use of the target. The graphite back is extended outward toward the cap outer edge to increase a thermal storage of the graphite, and a recess is formed into the cap to maintain a selected moment of inertia of the target and thereby maintain the rotordynamics of a given X-ray tube.

摘要： Polishing pads with a polishing surface layer having an aperture or opening above a transparent foundation layer are described. In an example, a polishing pad for polishing a substrate includes a foundation layer having a global top surface and a transparent region. A polishing surface layer is attached to the global top surface of the foundation layer. The polishing surface layer has a polishing surface and a back surface. An aperture is disposed in the polishing pad from the back surface through to the polishing surface of the polishing surface layer, and aligned with the transparent region of the foundation layer. The foundation layer provides an impermeable seal for the aperture at the back surface of the polishing surface layer. Methods of fabricating such polishing pads are also described.

摘要： A vertical conduction nitride-based Schottky diode is formed using an insulating substrate which was lifted off after the diode device is encapsulated on the front side with a wafer level molding compound. The wafer level molding compound provides structural support on the front side of the diode device to allow the insulating substrate to be lifted off so that a conductive layer can be formed on the backside of the diode device as the cathode electrode. A vertical conduction nitride-based Schottky diode is thus realized. In another embodiment, a protection circuit for a vertical GaN Schottky diode employs a silicon-based vertical PN junction diode connected in parallel to the GaN Schottky diode to divert reverse bias avalanche current.

摘要： Methods in OMA SEC_CF for providing security services to traffic over UDP between a client and a server and the relevant entities are provided. A pre-shared key is pre-shared between the client and the server. A pair of IPSec ESP SAs between the client and the server is established without shared key negotiation, wherein traffic data cryptographic algorithms are determined. Traffic data security keys are derived from the pre-shared key via the determined traffic data cryptographic algorithms. Then, data of the traffic can be provided with security services with the traffic data security keys through use of IPSec ESP.

摘要： A system and method for a Micro Electro-Mechanical System acoustic sensor, or MEMS acoustic sensor, to be used as an implanted microphone for totally implantable cochlear implants or middle ear implants is presented. The MEMS acoustic sensor comprises a coupler that attaches the sensor to an inner part of the ear, a MEMS acoustic sensor that converts acoustic vibrations into a change in capacitance, and a low-noise interface electronics circuit chip that detects the change in capacitance in the MEMS acoustic sensor, creates an signal representing a portion of the acoustic vibrations, and transmits the signal to one or more other devices, such as a cochlear implant. A method of fabrication enables the MEMS acoustic sensor to be fabricated as a small, less than 1 mm3, light weight, less than 30 mg, device suitable for implantation on a structure of the middle ear.
