The invention is a method and apparatus for processing an MPEG-like bitstream comprising information frames having associated timing parameters. The method and apparatus identify one or more non-referential information frames containing at least a threshold number of bits, remove one or more of the identified non-referential information frames and modify the timing information associated with each...

A method of operating a mobile communication system supporting data transmission between a mobile station (MS) and a network in a number of a different packet data protocols (PDPs) including a point-to-multipoint-multicast (PTM-M) protocol. PDP data is formatted and unformatted by a subnetwork dependent convergence protocol (SNDCP) according to the PDP of data. The PDP is identified to the SNDCP b...

A distributed method for creating telecommunications paths in a network, particularly after a span failure. The network includes plural distinct nodes interconnected by plural distinct spans, each span having working links and spare links. Each node has a digital cross-connect switch for making and breaking connections between adjacent spans forming span pairs at a node. At least one of the end no...

A cleaning and absorbing agent for petroleum-based products comprises a rigid, closed-cell polyurethane foam having a detergent entrapped within the cells. The cleaning and absorbing agent is preferably in particulate or granular form and may be combined with a suitable carrier. Method aspects of the invention are also described.

A television system for receiving a plurality of digitally-encoded television programs includes circuitry for selecting a particular digital data transmission channel from a plurality of digital data transmission channels containing a desired digitally-encoded television program in response to a control signal, at least one of the data transmission channels also including television program schedu...

A process for the production of an insulating component from a ceramic material for a high temperature fuel cell includes the following steps: In a first step, a ceramic material is converted into a dispersion by wet preparation with a water-soluble binder. In a second step, the dispersion is poured to form a water-containing layer. In a third step, the water-containing layer is converted at eleva...

The invention applies to heating and ventilation systems intended for private houses or corresponding buildings in which the circulating heating air is heated by means of heat pumps 10, 20. At least one of the heat pumps 20 functions as an ice machine or makes water freeze to ice and produces heat for the heating and ventilation system. The other heat pump 10 recovers heat from the outside air. As...

A transmitter is provided for communicating over a cellular system. The transmitter includes a data storage device electronically storing predefined information to be communicated to a receiving station over the cellular system. The predefined information may include one or more telephone numbers to be contacted in an emergency, medical information, or any other type of information. A positi on fi...
