Abstract: Decoding logic is arranged to receive an encoded data signal. The decoding logic comprises a convolutional decoder arranged to perform convolutional decoding on the encoded data signal, to produce a decoded data signal. The decoding logic comprises header bit prediction logic arranged to predict a value for at least one header bit within the decoded data signal, and to provide the predicted value for the at least one header bit to the convolutional decoder to be applied during convolutional decoding.

Abstract: A wireless communication system comprises a broadcast transmitter broadcasting textual and multimedia information to a remote receiver unit. The broadcast transmitter is operably coupled to a signal manipulation function and arranged to receive and process a broadcast signal that comprises both a textual portion and multimedia information. The signal manipulation function separates the textual and multimedia information into multiple bursts of data sub-blocks, wherein substantially each sub block comprises the textual data and a sub-block of multimedia information for transmitting to the remote receiver unit. By implementing the aforementioned inventive concepts, faster access to the most important (i.e. semantic) part of the transmitted information can be obtained.

Abstract: The present invention is directed toward a timepiece, such as a watch, having a protective cover with a gem set therein. The protective cover may be crystal, plastic or any other transparent and durable material. The protective cover has an aperture having concentric cuts. The setting is seated in the aperture and secured to the protective cover. The setting is configured to be of a similar size and shape as the aperture so that it may be securely affixed to the protective cover. A gasket may be inserted between the setting and the aperture to create a watertight seal in the watch cover. The timepiece may also have a hinged, hidden compartment on the backside of the watch frame. Engravings may be made in the hidden compartment, and small, thin objects may be stored therein.

Abstract: A power amplifier valve with a grid is disclosed having improved reliability of operation and lifetime of the valve. A screen grid of a tetrode has a mesh grid with vertical or oblique rods in pyrolytic graphite. According to the invention, the rods are provided with a greater width at the bottom of the grid near the output of the valve where the high-frequency currents are greatest.

Abstract: An electron tube with concentric, cylindrical electrodes has at least one meshed type of grid, a mesh being defined by several rods in contact by their ends, each point of contact forming a node. In order to limit the grid current, the surface area of a node is reduced. Only three rods leave each node. The meshes are hexagonal.
