Compounds represented by general formula (I), their stereoisomers, tautomers, derivatives, prodrugs or pharmaceutically acceptable salts, and their preparation methods or uses for the manufacture of a medicament of analgesics. In which R1 is selected from H, substituted or unsubstituted phenyl, or substituted or unsubstituted heteroaryl; A is bond, or saturated or unsaturated straight-chain or branched-chain hydrocarbon radical; R2, R3 are each independently hydrogen or methyl, which linked with any position of spirocyclo-structure; n and m are each independently integer between 0-2, do not represent 0 at the same time; B and D are each independently C1-C3 straight-chain or branched-chain alkylene; Y is selected from —CHR4—, O, S, —S(O)—, —SO2—, —NR4— and substituted or unsubstituted phenylene, in which R4 represents H, C1-C6 saturated or unsaturated alkyl, methyl or ethyl substituted by substituted or unsubstituted aryl or heteroaryl; and X− is pharmaceutical acceptable organic or inorganic anion. These compounds can be used as muscarine receptor (M-receptor) and/or nicotine acetylcholine receptor (N-receptor) agonist or antagonist. These compounds have good analgesic effect without side effect such as addiction.

A backlighting system for a cabinet sign may include a plurality of panels. Each panel includes a plurality of light emitting diodes (“LEDs”) attached to the panel. The diode has a box sign depth factor of less than about 1.4. An integrated circuit may also be located on the panel. A wire physically connects adjacent panels.

Provided are devices and methods for transmitting two or more data streams through the same cable. An exemplary cable includes at least two sets of conductive points, each set capable of independently transmitting a separate data stream. The cable may be a USB 2.0 type cable, with two contacts assigned for transmitting one data stream, and two other contacts assigned for transmitting another data stream. In some embodiments, one data stream is an audio-video signal transmitted to an audio-video receiver.

A wireless communication system (20) includes backhaul congestion control. Whenever congestion is detected on the backhaul, a flow control message sets a window size to a reduced window size to reduce or eliminate packet drops and to facilitate alleviating the congestion condition. A disclosed example includes detecting backhaul congestion and responsively reducing an available backhaul receiver buffer space factor used for setting the window size for a subsequent backhaul transmission. In a disclosed example, the buffer space factor is gradually increased back toward an actual available buffer space as the congestion status improves.

Disclosed are a scene video switch system and a scene video switch method. The system comprises an input unit configured to input an image currently captured by a video capture unit to serve as a current image; a detection unit configured to detect all of interesting elements and latent elements in the current image so as to determine a maximum possible existing area of the interesting elements; a state switch unit configured to carry out, by using a predetermined finite state machine, switching between scene states of the maximum possible existing area according to predetermined different scene states and switching conditions; and a display unit configured to extract, based on a current scene state switched by the state switch unit, an area of concern coinciding with the current scene state from the maximum possible existing area to serve as a scene video for display.
摘要:
A method and network device (e.g., a switch) is described for assigning virtual Ethernet bindings. The method may comprise accessing the network device to obtain information related to hardware (e.g., switching hardware) of the network device. Thereafter, an uplink binding from a plurality of physical uplinks is selected based on the information. A virtual network interface of a virtual machine is then mapped to the selected uplink binding.

A method performed by a processor allows an individual to update or maintain a database including a core and an extension. The core contains core tables including general data and the extension contains extension tables including specific data. The core tables and the extension tables have the same primary keys and the specific data are an extension of the general data. The method includes receiving an input from the individual for modifying the database, modifying the core using the received input, and automatically modifying the extension to reflect the modifying of the core.
摘要:
A touch control arrangement is arranged for a container having a foldable cover being folded between an opened position and a closed position via an actuation unit. The touch control arrangement includes a power source and a touch actuator electrically linked to the power source, wherein the touch actuator is located out of the storage cavity of the container body and is arranged in such a manner that when the touch actuator is activated by a presence of a touch, the actuation unit is actuated to move the foldable cover from the closed position to the opened position.
摘要:
Machine implemented method and system for transferring replicated information from a first storage location managed by a storage operating system at a first storage system node and accessible to a client computing system to a second storage location managed by a second storage system node are provided. A resource pool having a plurality of tokens is maintained for authorizing a replication engine to transfer replicated information from the first storage location to the second storage location. The number of available tokens is increased when traffic due to client requests for accessing the first storage location is less than a first threshold level. The number of available tokens is decreased for reducing transfer of information via the replication engine, when latency in responding to the client requests reaches a second threshold value and the traffic due to client requests reaches the first threshold value.
