Title: Video coder providing implicit or explicit prediction for image coding and intra coding of video.
Inventor: HASKELL BARIN GEOFFRY
IPC: H04N19/593
Filed: 1998-02-12
Abstract: A predictive video coder performs gradient prediction based on previous blocks of image data. For a new block of image data, the prediction determines a horizontal gradient and a vertical gradient from a block diagonally above the new block (vertically above a previous horizontally adjacent block). Based on thesegradients, the encoder predicts image information based on image information of either the horizontally adjacent block or a block vertically adjacent to the new block. The encoder determines a residual that is transmitted in an output bistream. The decoder performs the identical gradient prediction and predicts image information without need for overhead information. The decoder computes the actual information based on the predicted information and the residual from the bitstream.

Title: Satellite communications system and apparatus
Inventor: PAUL BARAN
IPC: H04J13/00
Filed: 1986-12-30
Abstract: A satellite communications system, which is inherently power limited, employing spread spectrum techniques in order to trade-off bandwidth for small ground station antennas. In a one-way system embodiment a central station (14) transmits data to a satellite (3) for relay to a large number of small antenna receiving stations (4), the transmissions being spread spectrum encoded with spreading code lengths selected to provide adequate data recovery at the least sensitive station to which the transmissions are directed. Spreading codes may also function to address particular stations. In a two-way system embodiment, the central station (14) additionally functions as a terrestrial relay station. A plurality of small antenna transmitting stations, at least one of which may be at the same site as a receiving station, transmit code division multiplexed data via the satellite to the central relay station using sufficiently long and distinct spreading codes as to permit adequate data error rates and to distinguish the transmissions of the various stations. The central relay station reformats the received data for retransmission to the satellite for relay to the receiving stations.

Title: Intelligent method for diagnosing mechanical fault of high-voltage isolating switch based on transfer learning
Inventor: YUNGUI ZHANG
IPC: G06N3/08
Filed: 2022-08-03
Abstract: The present disclosure relates to the technical ﬁeld of intelligent diagnosis for a high-voltage isolating switch, and in particular, to an intelligent method for diagnosing a 5 mechanical fault of a high-voltage isolating switch based on transfer learning. The method includes: obtaining a large number of power-time signals of a driving motor under various mechanical states of the high-voltage isolating switch by using an electromechanical co-simulation technology, training a multilayer neural network model by using the obtained simulation results as training samples, and further training last 10 several layers of the multilayer neural network by using experimental or ﬁeld measurement data as small samples, to achieve optimal parameters for a single or composite fault diagnosis model. The present disclosure can solve the problem of low accuracy of an intelligent diagnosis algorithm of the high-voltage isolating switch due to insufﬁcient training samples, and can improve the accuracy of the technology for 15 mechanical state diagnosis of the high-voltage isolating switch based on the deep neural network, thus making an intelligent diagnosis result of the high-voltage isolating switch recognized by industry.
Patent NL-273353-A (NL)
IPC: H01M50/414
Abstract: Synthetic ion-exchange material is made in the form of sheets, films, rods, cylinders or tubes, characterized by the presence of positive and negative groups on common macromolecules and a combined acidic and alkaline capacity of at least 0.3 meq. per gram.  The macromolecular material which forms the basis of the ion-exchange material is preferably polyethylene, but may also be composed of polymers of propylene, styrene, vinyl chloride, chlorotrifluoroethylene or tetrafluoroethylene, or of natural or synthetic rubber.  In the examples polyethylene film is exposed to accelerated electrons, and placed in styrene, which grafts on to the irradiated film.  The grafted styrene is successively chlorosulphonated, reacted with ethylene diamine or 3-diethylaminopropylamine, and hydrolyzed with sodium hydroxide to produce aromatic nuclei some of which bear acid groups and others of which bear basic groups.  Tertiary amino groups in the polymer may be quaternized with methyl iodide.

Title: Filter for removing particles from a gas stream
IPC: B01D46/32
Filed: 1968-11-11
Abstract: Device comprises a first and second screen, non-perforated strips extending between the screens and forming almost parallel channels which are not connected to each other, the channels being arranged at an acute angle with regard to the screens. Provision is made for a granular filter material arranged in the channel and occupying the greater part of the space in each channel, but considerably less than the entire volume of the channel, so that an air gap remains. These means forming air gaps for fluidizing the filter material by a reverse gas stream when the filter material is to be cleaned must be made up of collected particles, whereby the strips are installed so that the upper edge of a strip lies above the bottom edge of the strip immediately following, and whereby the lower periphery of the filter material determined by the angle of declivity lies above a straight line extending between the excess of the strips concerned. Use: in particular high temp. gas streams.
