893 results about "Code conversion" patented technology

In telecommunication, the term code conversion has the following meanings: 1. Conversion of signals, or groups of signals, in one code into corresponding signals, or groups of signals, in another code. 2. A process for converting a code of some predetermined bit structure, such as 5, 7, or 14 bits per character interval, to another code with the same or a different number of bits per character interval. In code conversion, alphabetical order is not significant. This article incorporates public domain material from the General Services Administration document "Federal Standard 1037C".

Electronic document delivery system employing distributed document object model (DOM) based transcoding and providing interactive javascript support

Several different embodiments of an electronic document delivery system are described including a client machine (e.g., a palmtop / handheld computer or wireless communication device) coupled to a transcoder proxy. One embodiment of the system allows a client machine with limited resources to support JAVASCRIPT. The transcoder proxy receives an electronic document in a first digital format (e.g., HTML or XML). A JAVASCRIPT event may be associated with an element of the document including JAVASCRIPT code executed in response to the JAVASCRIPT event. The transcoder proxy assigns a unique identifier to the element, and forms a model of a logical structure of the document (e.g., a document object model or DOM). The transcoder proxy uses the model to produce an “original” script including a portion of the document expressed in a second digital format (e.g., a scripting language), and provides the original script to the client machine. The client machine uses the original script to display / present the document portion. The client machine associates the JAVASCRIPT event with the element identifier, generates the JAVASCRIPT event in response to user input, and provides JAVASCRIPT event information and the associated identifier to the transcoder proxy. The transcoder proxy accesses the element within the model using the identifier, executes the JAVASCRIPT code producing a result, uses the model and the result to produce a “modification” script, and provides the modification script to the client machine. The client machine uses the modification script to modify the displayed / presented portion of the document.

Procedure for exchanging useful information generated according to different coding laws between at least 2 pieces of user terminal equipment

If TDM connections are through-connected from the originating TDM network to the target TDM network via a data network in the form of backbone, e.g. VoIP, the switchover between the TDM network and the data network takes place via media gateways. As is the case with connections exclusively between TDM, the coding algorithms of the A face and the B face have to be identical. In TDM networks, coding is done according to A Law and μ Law. When switching from an A Law network to a μ Law network, the coding specifications have to be converted. In order to carry out a conversion in a TDM environment, at the switchover point the μ Law face has to convert to A Law. The same applies to VoIP. The invention relates to the integration of this switchover conversion rule in the codec negotiation procedure so that in principle a μ Law A face offers μ Law and, alternatively, A-Law to the B face; a μ Law B face accepts μ Law whereas an A-Law B face acknowledges A-Law. Furthermore, 64 kBit/s unrestricted preferred connections are considered in fall back mode, wherefore an additional logic is integrated into the codec modification procedure by means of which in principle μ Law and, as an alternative, A-Law are offered to the B face in addition to the transparent CODEC or instead of offering a μ Law A face to the TMR only. The B face first accepts the transparent CODEC on the basis of the list or the TMR ‘64 kBit/s unrestricted preferred’. When receiving the TMU, the B face selects the Codec to satisfy the code conversion rule.

Vehicle dynamic information system based on GPS (global position system) satellite positioning and ECU (electronic control unit)

The invention provides a vehicle dynamic information system based on GPS (global position system) satellite positioning and an ECU (electronic control unit). The vehicle dynamic information system comprises a vehicle information acquisition module which is used for acquiring GPS positioning information and status information of a vehicle and is arranged on the motor vehicle, and a vehicle GPS data analysis module, a vehicle status data analysis module, a video data analysis module and a GIS (geographic information system) module which are arranged on a service side, wherein the vehicle information acquisition module can automatically obtain GPS positioning data and vehicle travelling computer data; after data compression and code conversion, the data is transferred to a gateway server to be received through a GPRS (General Packet Radio Service)/GSM (Global System for Mobile Communications) network; the gateway server can convert and decode the data to obtain a terminal original record which is then stored in a database; an end user can access the system through a WEB browser and can check the vehicle dynamic data. The vehicle dynamic information system provided by the invention has the advantages that the problems such as poor transportation safety, traffic jam and environmental pollution are effectively solved, the traveling efficiency of the vehicle is also improved, the probability that the vehicle is stolen is lowered, and the private use of government vehicles is reduced.
