摘要:
The present invention discloses methods and apparatus for constructing optical switch systems, in which any input optical signals can be routed to any output ports. The methods and apparatus provide advantages of configuration flexibility, modular construction, constant signal loss, and minimal numbers of switch units required. The switch systems comprise M×N switch modules. The switch module in turn comprises a two-dimensional waveguide array and a number of waveguide grating-based wavelength selective switches. With the capability of wavelength-selective routing provided by the switch modules, the optical switch systems requires a relatively small amount of switch units to extend into a very-large-scale switch system.

The present invention is a wavelength-selective optical transmission system that includes a first waveguide for transmitting a multiplexed optical signal therethrough. The system further includes a second waveguide coupled to the first waveguide wherein a least one of the first and second waveguides have a set of wavelength-selective Bragg gratings disposed near a coupling section between the first and second waveguides to reflect a reflecting optical signal back to the first waveguide and for transmitting a contra-directional optical signal and a co-directional optical signal having respectively a contra-directional selected wavelength and a co-directional selected wavelength corresponding to the Bragg gratings. One of the contra-directional and co-directional wavelengths is chosen as a designated wavelength, and the reflecting optical signal and one of the contra-directional or co-directional optical signals are outside of a predefined range surrounding the designated wavelength.

In accordance with an embodiment of the invention, there is provided a system for power generation from a fluid, such as air or water. The system comprises a rail tether, and a working umbrella movably mounted to the rail tether such that the working umbrella is powered by the fluid in a first direction along the rail tether during a working stroke of the working umbrella. A working tether couples the working umbrella to a generator during at least the working stroke of the working umbrella, and a motor is coupled to the working umbrella during at least a recovery stroke of the working umbrella, the recovery stroke being in an opposite direction to the first direction along the rail tether.

A web page is rendered under the control of a client. A content server divides a webpage in multiple empty partitions. Each of the partitions has an associated pointer to data that can populate the partition. When data changes, the content server transmits pointers for all data for all of the partitions, including new pointers to new changed data. If an old pointer to old data is the same as a new pointer to the new data, the client ignores the new pointer. If the new pointer and the old pointer are different, then the client uses the new pointer to obtain the new data for that particular partition.

A computer implemented method, an apparatus, and a computer usable program product are provided for configuring and modeling server connection and deployment information in an enterprise tooling environment. A software model is provided that comprises a connections object, which includes a plurality of connection objects and deploy spec objects. Each of the connection objects is specific to a backend server type. A deploy controller is provided at run time to examine the connections object for a connection object. A backend resource manager is loaded for a specific application server. If a connection object is present, the backend resource manager loads a connection interpreter, which transforms development time connection information in the connection object to the run time connection information in corresponding deploy spec object and connection factory spec object. The backend resource manager then writes the deployment information to the configurations files of the application server.

The use of extract form Wangla (coeloglossum viride (L) Hartm. Var. Bracteatum (Willd.) Richter), succinate derivative esters, and a derivative and pharmaceutical acceptable salts thereof, for the manufacture of a pharmaceutical preparation for the treatment of dementia, particularly for the treatment of Alzheimer' disease and Vascular dementia. Through Animal experiment, it has been demonstrated that, succinate derivative esters can improve learning and memory ability in dementia rats induced by scopolamine and cyclohexenyl imine; improve learning and memory ability in dementia rats induced by β-amyloid; improve learning and memory ability in dementia rats induced by permanent ligation of bilateral carotid; and improve memory ability of normal animals. It has the advantage of high activity, low toxicity and no inhibition to cholinesterase.

摘要:
There is provided a mechanism for opening and closing a working umbrella of a kite-guided umbrella ladder system. The umbrella ascends when in an open state and descends when in a closed state. Huge pulling power is introduced by the working umbrella when it is ascending, which can be used for power generation. A system with a common rail tether and multiple working umbrellas is provided for efficient and large scale power generation.
