    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.

    摘要: The present invention provides a bistable chiral tilted-homeotropic nematic liquid crystal (BCTHN) display, which can be switched between the tilted-homeotropic state (TH state) and the twisted state (T state) by using dual frequency liquid crystal material. These two states can be maintained without the application of any electric field. In contrast to the conventional liquid crystal displays, the bistable liquid crystal display according to the present invention does not need high voltage to induce the flow of liquid crystal or break the anchoring energy. Only 5-volt pulses are required to switch between these two stable states.
