Abstract: An exemplary monitoring device includes: a time chip connected to a connector to generate a time signal and a count signal when the connector is working, the time signal indicating how long the connector is in use, the count signal indicating that the total number of times the connector has been used should be incremented by one; a processor connected to the time chip to receive the time signal and count signal, and generate a data signal including a total service time and a total number of times the connector has been used; a clock generator connected to the processor to provide a clock signal; and an output port connected to the processor to output the data signal. The monitoring device keeps a watch on a connector for showing the service information about the connector to make an operator know if the connector needs to be replaced.

Abstract: The inventors have envisioned a multihop network scenario in which nodes are equipped with advanced multi-antenna arrangements, and recognized the advantage of exploring the presence of such advanced antenna arrangements in multihop network nodes for the specific purpose of determining link cost for routing in the network. A basic idea of the invention is therefore to determine link cost for a wireless link between a pair of nodes in the network based on multi-channel characteristics between the nodes, where at least one of the nodes is configured for operation with multiple antennas to provide for multiple channels. These multi-channel characteristics may for example be determined based on explicit channel matrix estimation and/or the number of transmit and receive antennas or other information on the antenna capabilities of the involved nodes. The determined link cost information may subsequently be used together with additional routing cost information for route determination, and packet forwarding.

Abstract: In a method for relaying deployment in a wireless communication system comprising a transmitting node with multiple antennas for communicating with at least one receiving node via at least two relay nodes, a data stream at the transmitting node is partitioned into at least two data substreams, each of which is beamformed and transmitted over a first link to a respective of the relay nodes; subsequently at least one restorable representation of each received substream is forwarded over a second link to the receiving node from the two relay nodes; and finally the received and decoded representations are multiplexed to form an output signal at the receiving node corresponding to the original data stream.

Abstract: The present invention relates to an integrated engine for beach cruisers comprising a speed variator, a rear gear box component, a shaft, a left crankcase component and a left crankcase cap component; the rear gear box component, the left crankcase component and the left crankcase cap component are connected to form a closed housing structure; the present invention also comprises an engine, a differential and a gear shift device; the engine is directly connected with the speed variator; the differential is disposed between the speed variator and the shaft; the speed variator comprises an automatic indefinite speed variator mechanism and a gear double reduction mechanism; the gear shift device is disposed in the gear double reduction mechanism; the differential can be manually operated so as to actuate or cancel the differential function. The present invention of the above structure allows users to opt for the reverse gear and differential function.

Abstract: An exemplary keyboard includes a first keyboard unit having a container defined in a side thereof, and a second keyboard unit pivotally attached to the first keyboard unit. The second keyboard includes a handle to drive the second keyboard unit to rotate between a first position in which the second keyboard unit is accommodated in the container of the first keyboard unit, and a second position in which the second keyboard unit is outside the first keyboard unit.

Abstract: The present invention relates to a small four-stroke gasoline engine with oil mist lubrication. The lubrication oil way of the engine includes a crankshaft chamber B, a camshaft chamber C, an upper rocker arm chamber D and a condensation chamber E. The camshaft chamber C communicates with the upper rocker arm chamber D via a tappet cavity 13. The upper rocker arm chamber D communicates with the condensation chamber E. An oil mist chamber A is surrounded by an upper case body 3 and a lower case body 4 at the side of the crankshaft chamber B, the bottom of the oil mist chamber A communicates with the crankshaft chamber B. An oilsplash impeller 2 is fixed on a crankshaft, which extends into the oil mist chamber A. An oil way 12 is provided on the upper case body 3 between the oil mist chamber A and the camshaft chamber C. An oil return way 15 is provided on a cylinder head assembly 5. An oil return way 14 is provided on the upper case body 3.

Abstract: An apparatus for the verification of compressed objected-oriented video bitstream includes a set of verifier models: Video Complexity Verifier (VCV), Video memory Verifier (VMV) and Video Presentation Verifier (VPV). The models specify the behavior of a decoder for variable VOP size and rate and define new parameters and bounds to measure and verify the computational and memory resources that the bitstream demands. They can be used in the video encoder or in the verification of pre-compressed video distribution.

Abstract: A method for automatically switching windows of different sizes particularly shown in a small display screen of a compact portable personal computer by means of determining a current position of a cursor and a key typed by a user is disclosed. By utilizing this, a larger window switching to a smaller window or vice versa is carried out automatically by the computer, thereby enabling a convenient operation.

Abstract: Melt extrudable grafts of emulsion polymerized silicone rubber and polyacrylate rubber hybrids have been found to be valuable impact modifiers for organic thermoplastic polymeric materials. Optimum impact modifier properties are achieved by employing as a source material, an emulsion polymerized silicone rubber made under semi-continuous, low shear process conditions.
