A system for cabling infrastructure that includes at least one port, at least one shutter, at least one sensor and a gateway is provided. The port is configured to be selectively coupled to a connector. Each shutter is configured to have an open state that allows access to an associated port and a closed state that covers the port. Each sensor is configured to sense the open state and the closed state of an associated shutter and generate shutter state signals that include information relating to a current sensed state of the associated shutter and an identification of a port that is associated with the associated shutter. The gateway is in wireless communication with each sensor to receive the shutter state signals. The gateway is configured to communicate the shutter state signals that indicate a change in a state of an associated shutter to a remote location.

A method operates a supply system having a measuring unit and a central unit. Information is transferred repeatedly at specific time intervals via a communication network by radio between the central unit and the measuring unit. The measuring unit or the central unit receives the information and then generates a receipt confirmation, which it transmits to the central unit or the measuring unit respectively. The central unit or the measuring unit, after transmitting the information, opens a receive window of a certain time length for receiving the receipt confirmation. As a result of a first trigger event, the time intervals between the repeat transmissions of the information are shortened, and/or an additional receive window for receiving the receipt confirmation is opened, and as a result of a second trigger event, the time intervals between the repeat transmissions are lengthened, and/or no additional receive windows are opened.

An information collecting system includes a first device including a counter, a second device that collects data from one or more sensing devices in response to a command from the first device, and a third device including a time-measuring unit that manages time. The first device adds, to the data collected by the second device, a first count value output from the counter at a timing when the second device collects the data, to generate a first data set. The third device adds, to the first data set, a correspondence relationship between a time output from the time-measuring unit and a second count value output from the counter of the first device.

A data collection method uses a receiver having data collection sensitivity to signals originating from objects dispersed in a field that is subject to distortion. The sensitivity of the receiver is swept along a first arc. For each of the objects detected during the sweeping step, two of the signals are collected at two different points in time. A difference between the two signals is compared to a threshold. When the difference exceeds the threshold, the sensitivity of the receiver is re-swept along a second arc that is angularly less than the first arc. When the difference is less than the threshold, the signals are captured.

Electric meters are connected by an electricity supply network to a data concentrator with which the meters communicate by powerline. A method for reading information from meters is based on a classification of the meters in a plurality of classes. A first class, read first, groups together meters that haven't been read in a last execution of the method. The other classes group together the meters according to a rate of response to requests for information coming from the concentrator. The classes grouping together the meters that have the lowest response rates are read last. In each class, each meter is classified according to information representing a topology of the network having an influence on the failure risk of the transmissions of information by the meter. The concentrator accounts for the classification of the meters when the meters in the network are read to reduce occurrences of periods of contention.

A security network provides reduced power consumption and more robust communication of messages in comparison to conventional wireless systems. Reducing power consumption as discussed herein ensures that the security system is able to operate for a long duration of time, potentially with minimal or no power from an electrical grid. Additionally, redundant communication paths as discussed herein provide a more robust way of selectively forwarding security data to a remote server. The availability of multiple communication paths ensures that a respective remote target recipient such as a server resource or remote communication device operated by a user can be notified of a trigger event during power failure conditions, such as when certain communication functionality of a security system is disabled.
