Disclosed is a solid state dye-sensitized solar cell employing a composite polymer electrolyte, which includes a photoelectrode, a counter electrode, and an electrolyte interposed between the photoelectrode and counter electrode. The electrolyte includes at least one of a middle molecular substance, a polymer mixture, and inorganic nanoparticles, and a redox derivative. The dye-sensitized solar cell reduces crystallinity of the polymer electrolyte to significantly increase ionic conductivity, and enables the polymer electrolyte to smoothly permeate into a titanium oxide layer to improve mechanical properties, thereby significantly increasing energy conversion efficiency. Accordingly, the dye-sensitized solar cell assures high energy conversion efficiency without an electrolyte leak, and thus, it can be stably and practically used for a long time.

An asymmetric network system manages bandwidth allocation and configuration of remote devices in a broadband network. A modular architecture of the system permits independent scalability of upstream and downstream capacity separately for each of the upstream and downstream physical paths. Allocation of downstream bandwidth to requesting devices is made according to bandwidth utilization by other devices, bandwidth demand by the requesting remote device, class or grade of service by the requesting remote device or bandwidth guaranteed to other remote devices. Configuration parameters remotely managed by the network include device addresses (global and local), transmission credit values, upstream channel assignment and upstream transmit power level. Further, management of device configuration profiles and bandwidth allocation occurs through control and response packets respectively generated by the network and the remote devices according to network operating software located at both ends. Control packets include poll packets that request, among other things, demand for an upstream transmission. Configuration packets instruct remote devices to assume an operational state or return status or statistical data. Response packets transmitted by the remote devices provide information to the network operations center for control purposes or to confirm the state of operation of remote devices, including channel operating statistics, errors, noise, etc. in order to remove or reallocate assigned upstream channels. Downloadable network operating software enables the network operator to upgrade remote operating software or to reconfigure the response profile of the remote devices. Account administration and usage reports are also generated. IP or ATM encapsulation, as well as forward error correction and encryption, are employed in the broadband network which may include an RF, satellite and cable medium with or without a telephony or router return path.

The invention provides a frame locking device for eyeglasses, comprising a locking groove and two locking bumps. The locking groove is provided on an outer edge of a lens, and extends perpendicularly to a surface of the lens. The two locking bumps are provided on a side portion of a frame, apart from each other so as to lock the lens by fixing the outer edge of the lens. A part of the side portion of the frame disposed between the two locking bumps is fitted into the locking groove. Less than half of the side portion of the frame disposed between the two locking bumps may be fitted into the locking groove of the lens. The side portion of the frame disposed between the two locking bumps may comprise elastic parts so as to be pressed to be inserted into and plucked out of the locking groove.
摘要:
The present invention is directed to new methods for combining, processing, and modifying existing materials, resulting in novel products with enhanced mechanical, electrical and electronic properties. The present invention provides for polymer/carbon nanotube composites with increased strength and toughness; beneficial for lighter and/or stronger structural components for terrestrial and aerospace applications, electrically and thermally conductive polymer composites, and electrostatic dissipative materials. Such composites rely on a molecular interpenetration between entangled single-wall carbon nanotubes (SWNTs) and cross-linked polymers to a degree not possible with previous processes.

A channel equalizer includes a channel estimator, a coefficient calculator, a multiplier, and an error remover. The channel estimator estimates a channel impulse response (CIR) of input data in which a known data sequence is periodically inserted. The coefficient calculator calculates equalization coefficients using estimated CIR, and the multiplier multiplies the input data with the equalization coefficients for channel equalization. The error removes estimates a residual carrier phase error of the channel-equalized input data and removes the estimated phase error from the input data.
