Abstract: A device for generating audiovisual display signals, including a first input terminal receiving content signals representative of an audiovisual event, the signals including insertion points indicating the output of an advertisement, a second input terminal receiving ad signals representative of an advertisement, a first buffer storing the ad signals, and a processor converting the content signals into display signals of the event and converting ad signals stored in the first buffer into display signals of an advertisement upon detection of an insertion point.

Abstract: In a satellite control system, a liquid is ejected by thermal ejection from holes in a substrate structure to create a reactive force on the satellite allowing the position, such as the attitude, of the satellite to be adjusted.

Abstract: Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's computer-based user station. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to have recorded for unlimited playback, for example, by a “CD burner”. An “ID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction.

Abstract: Movies are distributed to customer households in a secure format on digital media such as optical disks for playback via proprietary set-top boxes. A system operator produces movie disks in large quantities and delivers the disks to widely geographically dispersed distribution agents. Agents produce copies of the disks with unique agent identification codes embedded therein, and distribute the disks to local customers who have compatible playback devices. When customers view movies, information identifying the movie and a distribution agent who is responsible for the movie being distributed to that customer are communicated to the central computer of the system operator. The content providers are then paid royalties due and responsible distribution agents are compensated.

Abstract: A method using concurrently and simultaneously certain control factors for in-cylinder combustion, at least two of such factors being at levels never tried before by the prior art. The combination of control factors comprises: (i) high pressure charging of supply air for enhanced excess oxygen; (ii) advanced techniques for improved in-cylinder mixing of fuel and air (i.e., high swirl, reentraining piston bowl configuration, high compression ratio); (iii) high pressure injection of diesel fuel at levels of 16-22.times.10.sup.3 psi; (iv) smaller fuel nozzle ports for creating finer droplet size; (v) retardation of fuel injection from TDC by 2.degree.-5.degree.; and (vi) limitation of the ingress of lubrication oil into the combustion chamber by use of noncompressed cylinder sleeves to enhance piston to bore concentricity and preferably by other augmenting limits.

Abstract: The present invention is a method of forming large device quality single crystals of silicon carbide. The sublimation process is enhanced by maintaining a constant polytype composition in the source materials, selected size distribution in the source materials, by specific preparation of the growth surface of seed crystals, and by controlling the thermal gradient between the source materials and the seed crystal.
