According to one aspect of the present invention, a multi-antenna transmitter is provided. The transmitter includes: a data block acquiring device for acquiring multiple data streams, wherein each data stream includes data blocks at multiple slots; and a grouping and mapping device for grouping and mapping each data block, wherein the data blocks at the same slot in each data stream are grouped according to the number of the antennas and each group is mapped to one of the antennas respectively, and the different data blocks in the same group are mapped to different sub-bands respectively; and wherein grouping and mapping manners which are not exactly the same are adopted for the data blocks at different slots, and the grouping and mapping manners include data block grouping manners, group-to-antenna mapping manners, and sub-band mapping manners. And the groups of data blocks at the multiple slots are transmitted via the antennas. With the technical solutions of the present invention, a reduced PAPR during data transmission can be achieved while the diversity gain is guaranteed.

Provided are a single-card multi-mode multi-operator authentication method and device. An MAML in an AP receives an authentication request from a user, and authenticates hybrid networks found by a UE. Under the condition of determining that the authentication on each network in the hybrid networks is passed, the MAML receives terminal position information sent by the UE, and determines whether the terminal position information is the same as operator area information registered by the UE in advance, if so, the MAML acquires signal strength of each network and determines whether the signal strength of each network falls within a signal strength range covered by a base station under the network, if so, determines that all the networks in the hybrid networks are authenticated successfully, otherwise, determines that the authentication fails. The security in using an SIM card by a valid user and secure network service are ensured.

A method and apparatus for enabling a user to access a service provider is described. The user sends a request from a browser to a proxy server. The proxy server modifies the request by adding data (such as a URL) relating to a location of an identity provider able to provide user credentials for the user and forwards the modified request to the service provider. The modification of the access request may occur before the request is sent to the service provider or in response to an authentication request from the service provider. The data relating to the location of the identity provider may be provided as a header (e.g. an http header).

Hydroxy acid compound of substituted phenyl ester, preparation method and medical use thereof are provided. The title compound is shown in formula (I), Y═C14 straight carbon chain. The compound can release 2,6-diisopropylphenol rapidly under the action of enzymes in vivo, which has sedative, hypnotic and/or anesthetic effect. By protecting the hydroxyl group of 2, 6-diisopropylphenol in compound of formula (I), the first-pass metabolic activity of 2, 6-diisopropylphenol is reduced, so that the synthetic compound can be used for sedation, hypnosis, and/or anesthesia.

A MEMS electrostatic actuator comprises first and second opposing electrode arrangements, wherein at least one of the electrode arrangements is movable. A dielectric material (24) is adjacent the one of the electrode arrangements (22). The second electrode arrangement is patterned such that it includes electrode areas (26) and spaces adjacent the electrode areas, wherein the dielectric material (24) extends at least partially in or over the spaces. The invention uses a multitude of electrode portions as one plate. The electric field lines thus form clusters between the individual electrode portions and the opposing electrode. This arrangement provides an extended range of continuous actuation and tunability.

The present invention provides a method and corresponding device of processing and parsing a to-be-transmitted data packet in a communication network, such as a LTE system. A sub-header that is used for a header portion of a transmitted data packet is generated for each component data packet constituting the transmitted data packet, containing: original data packet ID for indicating an original data packet which the component data packet belongs to; segmentation processing ID for indicating times of segmentation happened to the original data packet in order to the component data packet, and a data segment which said component data packet belongs to after each segmentation; data amount IF for indicating a data amount of a data portion of the data packet. With the technical solution provided by the present invention, the header structure definition of a data packet is optimized, and the transmission resource utilization efficiency is improved.
