Abstract: Disclosed herein is a system for fastening an anchor in a borehole in a mineral substrate, in particular concrete, mortar or masonry, comprising an anchor having a core section and a thread section, and a grooving tool for grooving an internal thread in the borehole, the grooving tool comprising the following: a base body having a leading and a trailing end, a force application device being provided, via which a torque for screwing the grooving tool into the borehole and for grooving the thread is transmitted to the base body, the base body having an outer surface on which a grooving thread is formed, which is suitable for grooving the internal thread into the wall of the borehole, the following applying to the ratio of the length heff of the thread section of the anchor and the nominal diameter db of the borehole: heff/db?10.0, preferably ?12.0, particularly preferably ?15.0, and in particular ?30.0.

Abstract: The invention relates to a monitoring device for monitoring an energy parameter in a distribution station, wherein the monitoring device is designed to be attached to a voltage conductor in the distribution station, comprising: a device identifier for uniquely identifying the monitoring device, which device identifier is designed to be read out from immediate spatial proximity; a measurement unit for measuring an electrical current and/or a voltage of an alternating current flowing through the voltage conductor; an evaluation unit for determining the energy parameter based on the measured electrical current and/or voltage; and a communication unit for receiving a request from a readout device and for transmitting the energy parameter to the readout device if the received request comprises access information that is based on the device identifier.

Abstract: A system which determines whether to accept a wireless connection to a network device receives a request to initiate the wireless connection to the network device, and then determines, in response to the request, a nominal cell rate at which cells are exiting from a buffer in the network device for the requested wireless connection. Thereafter, the system determines an amount of buffer space in the network device required to accommodate the connection, and decides whether to accept the wireless connection based on the nominal cell rate and the amount of buffer space required to accommodate the connection.
