Abstract: A system (10) provides direct automated access to an online information services provider (34a-34n) through an address embedded in a video or audio program, commercial message, or news story. The system operates with video or audio programs which are received through broadcast, cable or pre-recorded media, and which are encoded in either analog or digital formats. The address of an online information provider is encoded in a vertical blanking interval or other non-displayed portion of an electronic signal which represents the video or audio program so as not to interfere with the program as displayed or transduced on a television (22) or audio sound (26) system. The online information provider address is detected (42) and decoded from the electronic signal and used in establishing a direct digital communication link (32) to the online information provider. Upon detecting an online provider address, the system indicates (46) to the user that more information is available. The user may then elect to establish a connection with the online information provider by giving a simple command, e.g., pushing a special button on a remote control (56). The system then automatically establishes a direct digital communication link (32) to the online information provider through the address and provides for interactive information exchange and processing to permit signals received from the online information provider to be displayed on a conventional television (22), transduced on a sound system (26), or also on a high resolution reproducing system (40) such as a computer monitor, or other reproduction device. <IMAGE>

IPC: E02D17/12
Filed: 1996-05-21
Abstract: PURPOSE: A method and a device for leveling and filling of ditches are provided to operate the leveling easily and to largely reduce the leveling material and the expensive fine material. CONSTITUTION: A method for leveling and filling a ditch is described, where a leveled layer of fine material is provided together with a contiguous layer of coarse material. A box-shaped device is described, having a height-adjustable rear end (11) which when raised and lowered will determine the leveling height of the fine material which is in the box-shaped frame and exits therefrom below the raisable and lowerable end wall when the box-shaped frame is moved through a ditch. Lateral projections (26, 27) on the end wall (11) bring about a simultaneous dispensing/apportioning of coarse material along the side of the leveled layer of fine material (3). Whilst the box-shaped frame is moved forward and dispenses the layer of fine material, the side projections (26, 27) will deal with the dispensing/leveling of coarse material thrown thereon. The box-shaped frame has a roof (16, 17) having crossfall, which will guide the coarse material down to the side. The roof (16, 17)can be opened to allow the box-shaped frame to be filled with fine material.

Abstract: PURPOSE: An apparatus for controlling a continuous outer power control loop is provided to control the outer power control loop regardless of data, by tabling frame error rates for signal-to-noise(SN) ratios, and by referring to the tabled frame error rates to decide whether frames have errors when the data is not transmitted in a discontinuous transmission mode of a code division multiple access(CDMA) communication system. CONSTITUTION: An apparatus for controlling a continuous outer power control loop comprises a cyclic redundancy check(CRC) error detector(925), a frame detector(924), a signal-to-noise ratio calculator(919), a data detector(927), and a frame error detector(929). If a frame is received, the CRC error detector checks an error of the frame to output a checked result. The frame detector measures energy of the frame to output the frame. The signal-to-noise ratio calculator calculates signal-to-noise ratios to output the ratios. The data detector receives the checked result and the frame energy to generate an existing frame flag message. The flag message presents whether a frame exists or not. If a frame received by the flag message exists, the frame error detector outputs the checked result to the outer power control loop. If the frame does not exist, the frame error detector estimates a frame error by the signal-to-noise ratios.
