Disclosed herein are systems, methods, and apparatus for improving the delivery of web content that has been authored for multiple devices. In certain embodiments, an intermediary device such as a proxy server determines the characteristics of a client device requesting multi-device content, obtains and examines the multi-device content, and in view of the particular requesting client device removes portions that are irrelevant for that device. Doing so can accelerate delivery of the content by reducing payload and relieving the client device of the processing burden associated with parsing the content to make that determination itself, among other things.

The present invention relates to a method whereby user equipment (UE) transmits channel state information (CSI) in a wireless communication system and to a device therefor. According to the present invention, a terminal receives configuration information for CSI reporting from a base station and receives a reference signal from the base station on the basis of the configuration information. The terminal may receive downlink control information (DCI) via a physical downlink control channel (PDCCH), calculate CSI about a particular channel on the basis of the configuration information and the DCI, and report same to the base station.

In a DTV transmitter the bits of shortened BCH codewords that exhibit undesirably low densities of ONEs are ONEs' complemented before being further coded, and used to modulate carrier waves. In a DTV receiver the further coding is decoded after demodulation. The results of such decoding are processed to recover successive shortened BCH codewords, some of which are in TRUE form and others of which have had their bits ONEs' complemented. Each shortened BCH codeword is extended to full length with ZEROs, and decoding is attempted. Successful decoding confirms that the shortened BCH codeword was received in TRUE form. If decoding is unsuccessful, the bits of the shortened BCH codeword as received are ONEs' complemented, extended to full length with ZEROs, and decoding is attempted. Successful decoding confirms that the shortened BCH codeword was received in ONEs' complemented form and has subsequently been converted to TRUE form.

Disclosed is a synchronous head sheave balance adjustment method for a multi-rope winding type elevator. When the multi-rope winding type elevator works, a container is elevated by two steel wire ropes through head sheave bodies. In the elevating process of the container, when the force applied to the steel wire rope winding around a head sheave on a hydraulic cylinder is larger, the corresponding head sheave body is downwards compressed through the first hydraulic cylinder, so that the force is reduced, and meanwhile, the steel wire rope is loosened for adjustment to a force balance with the steel wire rope on the other side. When the force applied to the other steel wire rope is larger, the corresponding head sheave body 1 is compressed downwards through the second hydraulic cylinder, so that the force is reduced, and meanwhile, the steel wire rope is loosened. When the force applied to the two head sheave bodies is unbalanced, pressure compensation is generated to the hydraulic cylinders; when the first hydraulic cylinder is compressed, hydraulic pressure pressurizes the second hydraulic cylinder for a balance through a communication device, so that the pressure balance of the second hydraulic cylinder and the first hydraulic cylinder is achieved after pressurization; the tension of the steel wire ropes of the multi-rope winding type elevator can be balanced and compensation can be conducted for non-synchronization flexibly and conveniently.
