Filed: 1999-10-18
Abstract: A method is provided for replacing compressed video from a first source with video from a second source at a predefined insertion point in a video data stream. If the video from the second source is progressively refreshed video, it is decompressed sufficiently prior to the insertion point to enable the recovery and recompression of a first video frame (in encoding order) from the second source to be inserted at the insertion point. The recovered first video frame is then recompressed as an intra-coded (I) frame. The insertion of the video from the second source is then commenced at the insertion point using the I frame. The insertion point can, for example, indicate the commencement of a commercial break in the video stream, in which case the second source provides a commercial for insertion into the commercial break. Where the commercial is stored in memory, it can be stored with the first frame thereof (in encoding order) as an I frame.

Title: Packaging material processing apparatus and method of producing packaging containers
Inventor: KUMETA YUKIHISA
IPC: B65B61/00
Filed: 1998-08-12
Abstract: The broken surface of a wrapping material (12) is prevented from becoming rough when a spout (21) is opened by applying external force. A wrapping material processor has means for conveying the wrapping material (12) having a multi-layered structure composed of a paper substrate and a resin film and a broken area (52) in a position corresponding to unsealing means; a device for sealing the wrapping material (12); and means for heating the wrapping material (12), arranged upstream of the sealing device in the direction of conveying the wrapping material (12) and opposite to the innermost layer of the wrapping material (12). The resin film of the wrapping material (12) is gradually cooled after being heated and melted, whereby the thermoplastic resin constituting the resin film is crystallized and enbrittled so as to prevent the resin film from being stretched when the spout (21) is opened by the application of external force by the unsealing means. Therefore, not only can the wrapping material (12) be easily broken, but also is the coexistence of the broken part and the stretched part of the resin film eliminated, so that the broken surface of the wrapping material (12) can be prevented from becoming rough.
Patent CA-2301937-A1 (CA)
Inventor: HOPPER ANDREW
IPC: G16H40/67
Filed: 1998-09-18
Abstract: The present invention provides a packet-based telemedicine system for communicating video, voice and medical data between a central monitoring station and a patient monitoring station which is remotely-located with respect to the central monitoring station. The patient monitoring station obtains digital video, voice and medical measurement data from a patient and encapsulates the data in packets and sends the packets over a network to the central monitoring station. Since the information is encapsulated in packets, the information can be sent over multiple types or combinations of network architectures, including a Community access Television (CATV) network, the Public Switched Telephone Network (PSTN), the Integrated Services Digital Network (ISDN), the Internet, a local area network (LAN), a wide area network (WAN), over a wireless communications network, or over an asynchronous transfer mode (ATM) network. Thus, a separate transmission protocol is not required for each different type of transmission media. Rather, a single transport/network layer protocol is used for encapsulating the information in packets at the sending end and for de-encapsulating the information at the receiving end. Furthermore, by sending the information in packets, the video, voice and measurement data can be integrated and sent over a single network.

Abstract: The invention relates to an access and billing method using a chip card in order to obtain services and/or support from telecommunications networks, supply networks and the like by utilising a decentralized subscriber connecting system with a peripheral counting and locking element and a subscriber connecting unit connected thereto. According to the method, a chip card having a first memory device for value points is made ready for use and/or initialized. Said value points provide authorization in order to obtain services and/or support of a determined system provider. A determined amount of money is transferred to the system provider and a quantity of value points corresponding to said amount of money is stored in the first memory device of the chip card. The decentralized subscriber connecting system is released and the corresponding services and/or support are obtained by means of a communication of the peripheral counting and locking element with the chip card which is inserted in the subscriber connecting unit. Finally, the quantity of value points corresponding to the obtained services and/or support are reduced. In a simplified billing method, transfer data is transmitted by means of a programming unit from a service provider/dealer to the customer via the chip card which is fed in his connecting unit. The data is confirmed there and is executed afterwards as normal bank transfers after another confirmation for the purpose of ordering services/goods.

Abstract: A reusable die for cold forging includes a metal casing, a bottom cover which has metal supporters welded on it and keyholes, and a film having desirable shape corresponding to the die cavity. The film is made of PET or PVC and provided at the top of the casing. Several layers of "cloth" of Kevlar fibre are placed into the casing, serving as upper stuffing, and several layers of stainless steel net are placed into the casing, serving as lower stuffing. The casing is inversed and covered by the bottom cover. Liquid mercury following steel balls or iron sand is filled into the casing from the keyholes until the casing is full. The mercury is rapidly cooled and solidified at a temperature lower than -40 ~C, so that the die which can withstand the force of cold forging is completed. After the processing of the forging, the die can be thawed under the room temperature, and the mercury can be reclaimed. By replacing the film with a new one and repeating the steps mentioned above, a new reusable cold forging die with desirable cavity shape is obtained.

Title: High speed ratioed cmos logic structures for a pulsed input
Inventor: MILSHTEIN MARK S
IPC: H03K19/096
Filed: 1998-12-22
Abstract: A logic structure adapted to receive pulsed active input signals produces a logical output with a very small inherent switching delay. In one particular embodiment of the present invention, a logic structure having PFET pullups (402, 406, and 410) and NFET pulldowns (404, 408, and 412), receives active low pulsed input signals (A, B, and C) and produces a logical high output signal (D) when all the input signals are at a low level. When at least one, but not all, of the input signals (A, B, and C) are low, the logic structure produces a logical low output signal (D), while sinking a DC current. When all of the input signals (404, 408, and 412) are at a high level, which is the default condition for this particular embodiment, the logic structure produces a logical low output signal (D), and no DC current paths are switched on.
