    摘要： A locating system includes a central server to receive and process data; a device to be secured or assigned to a person or asset, the device having one or more sensors configured to detect a distance from a plurality of physical structures, the distance being transmitted as raw data to the central server; a software installed on the server and providing a computer implemented drawing of a building or site, the computer implemented drawing having a database of floorplans associated with the building; and a unique identifier incorporated into one of the physical structures, the unique identifier to be sensed by the device and provide the device with a building information; the raw data is correlated to the database of floorplans to determine a first location associated with the device. Real time tracking is achieved via constantly collecting raw data to be compared to the database of floorplans and site plans.

    摘要： A security system uses tags that are able to receive time signals sent from the GPS satellites or the broadcasting radio signals from the cell towers and transmit the identification and location information or signals to the central database and server for triangulation/trilateration periodically or in the event of an emergency. A security system uses tags that are able to transmit RF signals to readers located around a college campus. The tags may transmit signals periodically or in the event of an emergency. Certain locations use LF readers with exciters that trigger a signal from the tag. The security system may provide quick identification and location of individuals in danger.

    摘要： The invention relates to a method for the agglomeration of iron-oxide-containing residual materials, in particular scale and mill scale, wherein the residual materials and paper sludge are dried and ground and agglomerates are produced, by hot briquetting, from a mixture of the residual materials and paper sludge so processed. In this manner, it is possible to produce mill scale briquettes of high strength and density. These briquettes can then be charged into an electric arc steelmaking furnace for the purpose of recycling the iron contained in the residual materials.

    摘要： Method for the reduction of echo and/or noise signals in TK systems for the transmission of useful acoustic signals, in which, when a silence interval is present, the distorted useful signal is modified by a time-dependent control signal ao(t) or by a control signal ao(k) cycled in the rhythm of a scan rate fT=1/T. The control signal ao(k) is varied in such manner that, during the presence of speech signals in the useful signals, the amplitude of the control signal ao(k) is set to a predetermined constant value co and, when a silence interval begins, the amplitude of the control signal ao(k) is reduced continuously from one sample value to the next in accordance with the recurrence formula ao(k+1)=ao(k).β with β

    摘要： A method of canceling echoes in a telecommunications system wherein an exchange of information takes place between a local subscriber and a subscriber at the remote end of a transmission link and at least one subscriber is assigned an echo canceller, the parameters of which are set as a function of an echo delay time (i). The signs of the signal x(t) transmitted by a subscriber and the signal y(t) received by the subscriber can be determined at equidistant time intervals (Ti) so that sign sequences arise which are stored and compared with one another, and in the event of a direct correspondence or a correspondence as a result of an inversion of the sign sequences of the received signal y(t) and of the transmitted signal x(t) the received signal y(t) is detected as an echo and the echo delay time (i) is calculated.
