A method for detecting islanding conditions in an electrical grid having a power line voltage includes monitoring a detectable signal different from the power line voltage at a generating station, superimposing the detectable signal onto the power line voltage at a grid point outside the generating station, and switching the generating station from a grid-connected mode of operation to an islanded mode of operation when the signal to which the detector is responsive is determined to be absent.

A system for performing channel estimation based on a received signal including both known (KS) and unknown (UKS) transmitted symbols, includes detector circuitry (CK1, ..., CKP,L; CM, DU) for detecting the unknown symbols (UKS) by assigning estimated values (EAS) to the unknown symbols, and channel estimator circuitry (M) for performing channel estimation by exploiting both the known symbols (KS) and the estimated values (EAS) assigned to the unknown symbols (UKS). The system has associated multiple receiving antennas. The system is preferably included in a CDMA receiver and the received signal includes known pilot bits (KS) and additional symbols, such as transmit power-control (TPC) commands, feedback information for transmitting antenna diversity, and a transport-format combination indicator (TFCI) that comprise the unknown symbols (UKS).

The invention relates to a fault detection method of a CPU (Central Processing Unit) module address and a data bus, and belongs to the technical field of manufacture of electronic products. The fault detection method comprises the followings steps of: firstly, setting wires of all IO (Input / Output) ports of the CPU into low level output states before operating an RAM (Random Access Memory); secondly, sequentially heightening a data wire in a continuous address range of the RAM, writing data into the data wire, and carrying out read-back verification on the data wire to detect the conditions of short circuit and open circuit of the data bus of the CPU; thirdly, sequentially heightening the data wire, writing different data in which the low positions are different and the high positions are 0 into the RAM, and carrying out read-back verification; and fourthly, carrying out the same testing on the data in which the high positions are different and the low positions are 0 to detect the conditions of short circuit and open circuit of the data bus of the CPU as well as the short circuit condition between an address bus and the data bus. According to the fault detection method of the CPU module address and the data bus, the problem of faults of the addresses and data buses of the CPU module caused by plate-making and welding in a large-scale production process can be quickly and reliably detected.

The invention relates to a master device (2) for monitoring and reporting memory usage in a connected device system including at least one subsidiary device (3, 3') to a remote entity (6) via a cloudservice (5), a system (1) for monitoring memory usage comprising said master device (2) and the remote entity (6), a respective method and a computer program for executing the method on the master device (2).

The invention discloses a handset power supply method and system. The method can realize a function that a handset is compatible with a disposable battery and a lithium battery. The method comprises following steps: a battery mounting step in which the lithium battery or the disposable battery is mounted in a handset battery seat; a judging step in which a handset CPU judges that the mounted battery is the disposable battery or the lithium battery, if the mounted battery is the lithium battery, a lithium battery power supply step is executed, and if the mounted battery is the disposable battery, a disposable battery power supply step is executed; the lithium battery power supply step in which the lithium battery supplies power to the handset, and the handset is set in a rechargeable mode;the disposable battery power supply step in which the disposable battery supplies power to the handset, and the handset is set in a non-rechargeable mode. The technique scheme of the invention firstly judges the mounted battery is the disposable battery or the lithium battery, then determines whether providing the chargeable mode, in this way, not only the lithium battery and the disposable battery power can be used as the power supply of the handset, but also battery explosion accidents induced by miss-charging can be avoided.
