Digital signals, such as digitized television signals, are subjected to a source coding step in which a class of "most important" data elements represents a proportionately greater amount of the information to be communicated than the rest of the data elements. This is followed by a constellation mapping step which is carried out in such a way that those data elements have a lower probability of b...

The present invention provides a method and apparatus for automatically scrubbing ECC errors in memory upon the detection of a correctable error in data read from memory. This is performed by providing in a memory controller memory control logic for controlling accesses to memory, an ECC error checking and correcting unit for checking data read from memory for errors and correcting any correctable...

A video data communication system and method are disclosed which provides for the secure transmission of video data among devices connected to a video data bus. The video data is transmitted with address information corresponding to a particular device or, alternatively, video data is encrypted and transmitted on the data bus without address information.

A distinctive absorbent article includes a backsheet layer, and an absorbent structure superposed on the backsheet layer. The absorbent structure includes particles of high absorbency material, and a liquid permeable topsheet layer is superposed on the absorbent structure to sandwich the absorbent structure between the topsheet layer and the backsheet layer. A fibrous face sheet layer is incorpora...

A height adjustable conveyor system is disclosed for conveying articles between different heights as needed. The conveyor system includes guides that support the neck rings of articles to be conveyed, and the guides are mounted on an air conveyor having multiple sections so that the guides are caused to be flexed by different movements of the air conveyor sections. The air conveyor has pivotably c...

The manure is fed into a hopper(3) of a solidifying apparatus(4) through transfer pipes(5, 5') by a motor pump(2). The manure is transferred to a collecting tank(12) by a screw(21), a moisture contained in the manure is discharged through a net(23) and a dewatering hole(24) in a conveyer case(25) rotating in association with chain gears(28, 28'), a connecting shaft(27) and gears(26, 26') in the op...

A flushable ostomy pouch having side walls composed of pH-sensitive material capable of dissolving when exposed to an aqueous fluid having a pH substantially above or below a neutral pH level, and containing a quantity of pH-modifying material to initiate dissolution of the pouch when it is discarded in the water of a toilet bowl, is disclosed. The pouch includes a pair of side walls and an extern...

An improved heat press for joining the spliced ends of a conveyor belt. The press includes an upper platen containing a flexible, inflatable bladder that is positioned to engage the upper surface of the spliced area of the belt. A lower platen supports the belt and includes an electric heating element that is supported on an aluminum block having a plurality of parallel internal flow channels. A l...

The invention relates to a process for concentrating fullerenes having more than 70 carbon atoms, which comprises a) applying a benzene or toluene solution of a crude fullerene extract to a chromatographic separation column charged with coke, anthracite and/or graphite as support material and subsequently b) desorbing from the separation column the fullerenes having more than 70 carbon atoms which...

The invention relates to a process for concentrating fullerenes having more than 70 carbon atoms, which comprises a) applying a solution of a crude fullerene extract to a separation system containing a preliminary column and a main column charged with coke, anthracite and/or graphite as support material, then b) decoupling the preliminary column from the separation system and c) desorbing from the...

Projector assembly consisting of a pair of two projectors, supplemented with a pair of lenses 5, 5' made of thermoplastic material, structurally integrated or partially interpenetrating each other, contained in a single external housing. The lenses 5, 5' are obtained by stamping, in a second stamp, of a plastic polymer 15, 17 on an insert 11, 13 of a plastic polymer previously produced in a first ...

The invention provides a method for evaluating the self-diagnostic system of a controller in a motor vehicle having a control panel with a push-button switch with automatic return, and additional input elements and having a signalling element which is suitable for emitting a flashing code. In order to emit a structured flashing code of fault numbers, the range of possible faults which can be diagn...

A servo control has an electromechanical or electrohydraulic support of setting strokes of a handle. A constantly running electric motor is coupled to a control member of the servo control by power flux which can be controlled by the handle. By way of an electronic load recognition, the load which is variable in dependence on the power flux and against which the electric motor has to operate is ut...

The invention relates to a method for defining the initiation sensitivity of an automatic braking procedure, in which method the threshold value for the initiation of an automatic braking procedure is reduced as a function of the pedal distance which has been traversed.
