摘要:
A local oscillator includes a phase-locked loop. The phase-locked loop includes voltage controlled oscillator (VCO) and a novel VCO control circuit. The VCO control circuit may be programmable and configurable. In one example, an instruction is received onto the VCO control circuit to change the power state of the VCO. The instruction is issued by other circuitry in response to a detected change in RF channel conditions (for example, a change in a signal-to-noise determination) in a cellular telephone. In response, the VCO control circuit outputs control signals that gradually widen the loop bandwidth of the PLL, then gradually change the VCO bias current to change the VCO power state, and then narrow the loop bandwidth of the PLL back to its original bandwidth. The entire process of widening the PLL bandwidth, changing the VCO power state, and narrowing the PLL bandwidth occurs while the PLL remains locked.

The present invention relates to a method and system for producing and delivering sterile, airless, and highly loaded ice slurry for inducing therapeutic hypothermia. The method is capable of producing and delivering ice slurry in a patient to induce hypothermia through internal and external cooling methods such as subcutaneous, intravascular, intraperitoneal, gastrointestinal, and lung methods. The method is capable of producing and delivering saline ice slurry or other phase-change slurries compatible with human tissues. Ice slurry is made by crushing, smoothing, and mixing ice slush in an airtight and self-collapsible liquid container, followed by being pumped out through flexible tubing and injection port into a patient body without air. The novel method and system are simple, and easy to use, which facilitate long term storage, immediately ready to use, and airless delivery.

The present invention is related to a backlight module and a liquid crystal display device, and includes a light source, a light guide plate, a back plate, a fixed retaining part and an elastic retaining part. The edge of the back plate is formed with a peripheral frame perpendicular to a plane of the back plate. One end of the elastic retaining part is connected to the peripheral frame, and the other end of the elastic retaining part is elastically connected to a surface of the light guide plate opposite to the light input surface. The cost of the present invention is low and the manufacture thereof is simple, while the deformation of the light guide plate due to the temperature can be transferred to a surface of the light guide plate opposite to the light input surface.

A method, device and system for judging a call type are disclosed in embodiments of the present invention. The method includes: receiving a call request from a calling terminal, where the call request carries a calling terminal number and a called terminal number; querying a number information storage server for plan information of the calling terminal number and/or the called terminal number according to the call request; and judging the call type of a call service corresponding to the call request according to the plan information of the calling terminal number and the called terminal number. In the embodiments of the present invention, a number information storage server stores and manages the number plan information uniformly, thus reducing the maintenance costs; and the method, device and system for judging a call type enable judging of the call type of a terminal.

Conductive material grids or lines embedded or partially embedded in a transparent substrate of a solar cell. The grids or lines can have a higher conductivity than the anode or they can have the same conductivity. The grids or lines increase the volume of the anode and, thus decrease sheet resistance of the same.

The present invention discloses a water-filtered dust collector, which comprises a housing with a handle. A battery package is disposed at one end of the housing, and a suction nozzle is disposed at the other end. A suction nozzle mounting is disposed at the bottom of the suction nozzle. A suction nozzle fixing bush is disposed between the suction nozzle mounting and the housing. An electric motor driven by batteries in the battery package and fan blades driven by the electric motor are disposed in the suction nozzle fixing bush and the housing. A water vessel is disposed on the suction nozzle mounting. An air steering pipe is disposed at a position corresponding to the suction nozzle on an end surface far from the suction nozzle of the suction nozzle mounting. An air inlet pipe is disposed on the septum of the suction nozzle fixing bush, with one end inserted into the water vessel to communicate the suction nozzle fixing bush with the water vessel. And therefore, it has the following advantages: easy for cleaning, as it is filtered by water; easy for replacing, as it is convenient to assemble and disassemble; environmentally friendly, as it can be reused; and saving the use-cost due to its high applicability.
