Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Idle Channel Broadcast in Mobile Radio Systems
Nikl, Kerstin Harenberg, Norbert Roettger
This is a method for distributing low priority information
in a two-way radio system by using the system's idle time. The system is
preferably a digital system, e.g. TETRA.
This paper describes a method for using idle time more
efficiently, in radio systems that use an infrastructure. This time is wasted
in some of these systems. Examples of these are systems are e.g. MPT1327 and
Problem To Be Solved
In current mobile radio systems network information and
system broadcasts are transmitted occasionally by the infrastructure as
required. This is e.g. as described in GSM and TETRA.
Proposed Solution to the Problem
Unlike the standard occasional TETRA or GSM broadcast
ability, this system uses it's idle time to transmit low priority information
to the mobile radios. Due to the fact that this transmission can be interrupted
at any time, e.g. by a call, an abort and resume mechanism is required.
This low priority information can then be stored as data or
audio inside the mobile radio unit. Sufficient RAM (random access memory) is
required in the mobile radio units to do this. The operator of the mobile radio
can evaluate and/or maintain the data when it is convenient to do so. It must
also be possible for the operator to select only desired (subscribed)
information, i.e. store only specific types of news, which have been selected
