Abstract: The invention relates to a method and a device for increasing a data throughput in network applications for the transmission of data at high speed, for example, the Internet, via a packet oriented cordless data network, for example, the GPRS network. The Internet application provides for data in the form of data packets (n, n+1, n+2, n+3, ...). In case of transmission via the Internet the data packets are transmitted via different paths, which is why the data packets are available to the GPRS network at an intermediate node in the wrong sequence. Also, data packets get lost, which upon a new request are available also in the wrong sequence. Due to a different bandwidth a number of data packets is available for transmission at the intermediate node of the GPRS network while a first data packet is transmitted. The sequence of the available data packets is determined and the data packets are sorted for being available for transmission in a sorted sequence.

Abstract: Apparatus for determining the frequency of an ac power signal, includes sensing circuitry to sense the ac signal. In a digital implementation of the invention, a double average of the samples is generated by a processor as the sum of the most recent sample, twice the next most recent sample plus the third most recent sample.  The least mean square of a running window of the most recent double average signals is generated to avoid discontinuities at the zero crossings and to reduce the effects of noise. The frequency is determined from this least mean square value of the window of double average signals. As implemented in a protective relay, a trip signal is generated if the frequency is out of limits.
