摘要:
A multiple input multiple output signal receiving apparatus includes a first antenna configured to receive a first radio frequency (RF) signal, a second antenna configured to receive a second RF signal, a superheterodyne receiver, a direct conversion receiver, and an antenna switching module. The superheterodyne receiver is configured to convert one or both of the first and second RF signals into at least one first analog signal. The direct conversion receiver is configured to convert one or both of the first and second RF signals into at least one second analog signal. The antenna switching module couples the first and second antennas to the superheterodyne receiver and the direct conversion receiver, and is configured to selectively direct the first and second RF signals to the superheterodyne receiver and/or the direct conversion receiver, depending on an antenna switch control signal indicating a signal quality derived from the first and second analog signals.

A method and apparatus for rapid and dynamic RF and Microwave circuit prototyping and integration provides a standard test fixture for testing any single device from any device vendors, provides a rapid dynamic tool for sub-system and system integration and prototyping, provides a flexibility to make any single function or multi-function assembled module quickly and economically. This prototyping approach can help RF/microwave companies share development times and costs. The combination of standard PCB function cells and dynamic standard mechanical cells helps build a prototype design quickly and reduce R&D costs.

A method of using photodynamic therapy to perform selective targeted therapy of biological tissue. The method includes intravenously injecting a porphyrin-based photosensitizing drug followed by irradiating the tissue with light while the drug is being injected. The duration of the irradiation and other parameters are controlled so that the selected biological tissue is treated and non-selected tissue is not damaged. By controlling the flow rate of the injection and other parameters, so that irradiation of the effected tissue overlaps with injection of drug, the target tissue is effectively treated without damage to non-target tissue.

A method, gateway, proxy and system for implementing mobile Internet services are provided, in which an AOG receives a first register request from a terminal application proxy, and establishes a first data link with the terminal application proxy according to the first register request; receives a second register request from at least one application server and establishes a second data link with the at least one application server according to the second register request; performs application data forwarding between at least one application client in a terminal and the at least one application server through the terminal application proxy, the first and second data links. Arrangement of an AOI system between a terminal application proxy and an AOG converges a large number of data links in the present mobile Internet, lowers the network load, reduces network resource consuming of mobile Internet applications and improves the utilization performance of mobile Internet.

摘要:
The present invention discloses a system for ensuring network quality of service (QoS), comprising: a QoS service controller (QSC) for extracting QoS request to network from service request, transmitting the QoS request to a DRC resource controller in the network, and transmitting resource-releasing information; a QoS pipe provisioning controller (QPPC) for provisioning pipes, obtaining information about the resource occupation condition of QoS pipes periodically, and adjusting the capacity of the pipes dynamically but not by real-time; a distributed resource controller (DRC) for processing the QoS request from the QSC dynamically, and implementing access control and resource distribution of each resource request. Based on this system, the invention also provides a method for distributing network resource in a layered way.
