Title: Transmission and reception of television programs and an additional data service
Inventor: KAARS PETER BERNHARD
IPC: H04H20/00
Filed: 1997-11-03
Abstract: A method and arrangement are disclosed for transmitting television programs via a plurality of channels, and an additional data service, for example, an Electronic Program Guide, via a selected television channel. While processing and displaying the program guide, prior art television receivers cannot continue the reproduction of a currently received TV program because the program is generally transmitted via a different channel. The invention provides a solution to this problem by duplicating a signal component representing, for example, the audio contents of the various television programs in said selected television channel.      This allows customers to keep up with the service they were watching before, and to immediately return to the program if something of interest appears to happen. The invention is particularly applicable in Digital Video Broadcast (DVB) systems where each channel can accommodate a plurality of TV programs.

Inventor: WURM JOHANNES
IPC: C21B13/14
Filed: 1997-03-03
Abstract: The invention relates to a process for the production of spongy metal from materials formed from metal ore. During said process a process gas containing CO and H2 and coming from a gas source (A, B) is compressed, optionally subjected to CO2 elimination and heating, and supplied as a reduction gas to a reduction zone (21). After reaction with the metal ore, said process gas is removed from the reduction zone (21) in the form of an export gas for further use for a consumer. For the reduction zone (21) to be supplied with sufficient reduction gas even when there is an incident, a process gas containing CO and H2 and originating from at least two gas sources (A, B) is supplied to said reduction zone (21) as the reduction gas, and the failure of one of the gas sources (A, B) is compensated in that at least one part of the export gas originating from the reduction zone (21) is re-circulated, said export gas undergoing compression, CO2 elimination and, optionally, heating, and being delivered to the reduction zone (21) along with the process gas originating from the other intact gas source(s) (A or B).

Title: Moving image composing system
Inventor: KATO HITOSHI
IPC: H04N19/00
Filed: 1998-11-12
Abstract: A moving image composing system for displaying reduced and encoded images at arbitrary positions on a multi-image raster. The moving image composing system comprises a moving image reducing unit for reducing a moving image inputted, a moving image encoding unit for encoding the reduced moving image to produce an encoded moving image, an accumulating unit for storing and accumulating the encoded image, and a moving image composing unit for combining more-than-one encoded moving images accumulated to produce a multi-image combined moving image. The moving image encoding unit performs the encoding processing to facilitate the change of positional information the reduced moving image has, in consideration with the case that the change of the position information occurs due to the disposition of the reduced moving image at its combination. When there is a need to change the positional information of the reduced moving image due to the combination processing, the moving image composing unit changes the positional information to positional information required for the combination processing.

Title: Arc fault detector comparing integrated interval to interval filtered load current and circuit breaker incorporating same
Inventor: ZUERCHER JOSEPH CHARLES
IPC: H01H9/54
Filed: 1999-06-02
Abstract: Arc faults are detected by bandpass filtering the current to generate a sensed current signal with a pulse each time an arc is struck. A resettable integrator integrates this sensed current repetitively over equal time intervals such as each cycle of the ac current. The integrated value of the sensed current is compared with the value for the previous corresponding time interval stored in a sample and hold circuit, with the indications of interval to interval increases and decreases in the integrated sensed values for a selected number, such as six, of the most recent time intervals stored in a shift register. For each time interval, a chaos detector counts the number of changes between increases and decreases for the selected number of most recent corresponding time intervals and accumulates a weighted sum of the counts which is time attenuated. When the sum reaches a predetermined amount, an output such as a trip signal for a circuit breaker is generated.

Abstract: In accordance with the teachings of the present invention, an optoelectronic system (10) is provided for surface digitization of an object using spatiochro-matic triangulation. The optoelectronic system (10) includes an illuminating subsystem (12) for illuminat-ing a measuring space (30) that contains an object (16) to be measured, as well as a viewing subsystem (14) for collecting the light reflected by this object (16) and for generating a three-dimensional topogra-phy of the object (16) using in depth chromatic coding of the object. More specifically, relay optics (22) are used to image a polychromatic light source (20) onto a source slit (24) which in turn passes images from the slit image onto a dispersing element (26). The ob-ject to be measured is illuminated with a continuum of monochromatic images along a cutting plane (x, z) within the measuring space (30). A color coded (x, a) representation, generated by the intersection of the cutting plane (32) and the surface of the measured ob-ject (16), is imaged onto a viewing slit of an imaging spectrograph. A relay lens (50) is used for project-ing this image onto the viewing slit (42). A grayscale imaging array (46) located in the image plane of the spectrograph (40) registers the color coded represen-tation, and by using spectrophotometric analysis, an image processor (40) translates this representation into a plane section of the three-dimensional topography of the measured object (16).
