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 wireless communication device that communicates with a plurality of slave units, including: a transmitter that transmits a data transmission instruction including a first identification information of a single slave unit among the plurality of slave units; a receiver that receives data corresponding to the data transmission instruction from the single slave unit; wherein the transmitter transmits to the plurality of slave units acknowledgment data which has incorporated second identification information into an acknowledgment to the data received from the single slave unit, the second identification information indicating another slave unit which transmits data corresponding to a next data transmission instruction to the wireless communication device.

A control apparatus is communicably connected to a first apparatus to perform a control on the first apparatus. The control apparatus includes a data collecting unit, a collection interval determining unit, and a storing unit. The data collecting unit collects, by polling and from the first apparatus, data in order to perform the control. The collection interval determining unit determines, based on a setting content of the control, a collection interval of the data collected by the data collecting unit. The control apparatus performs a plurality of the controls on one first apparatus. The storing unit stores, for each of the controls, one data item or a plurality of data items constituting the data. The storing unit further stores, for each of the data items, the collection interval.

The present invention relates to a method and system for gathering data along points of travel using common portable electronic devices that are typically used for other functions. More specifically, the data gathered by these portable electronic devices may be accessed, processed, validated, and used in conjunction with, or alone, to produce, augment, and/or validate other data sets across wide ranges of science and technology.

A method for transferring data blocks from a field device to a server, each data block including data describing an operation of the field device during a block time period is provided. The method includes setting a first and a second pointer delimiting a completed time period; and, until a predetermined transfer period elapses: transferring the data blocks having a block time period that is later than the second pointer to the server in a chronological order; and if all data blocks having a block time period that is later than the second pointer have been transferred to the server, transferring the data blocks having a block time period that is earlier than the first pointer to the server in an anti-chronological order. Data blocks can efficiently and reliably be transferred to the server.

A base wireless device includes a selection unit configured to select either signal transmission or standby, and a transmission processing unit configured to perform a transmission process of transmitting a signal to at least one remote wireless device in a case that the selection unit selects the signal transmission, and to stand by without performing the transmission process in a case that the selection unit selects the standby. The selection unit selects either the signal transmission or the standby in a current transmission/reception period in accordance with a predetermined rule in a case that the signal transmission was selected in a previous transmission/reception period, and selects the signal transmission in the current transmission/reception period in a case that the standby was selected in the previous transmission/reception period.

Devices state changes in a building may be determined using a combination of power monitoring and network monitoring. Power monitoring may be performed by obtaining a power monitoring signal and processing the power monitoring signal with models to determine information about state changes of one or more devices in the building. Network monitoring may be performed by receiving information about network packets transmitted by devices in the building and processing the information about the network packets to determine information about state changes of one or more devices in the building. For some devices and some implementations, information about state changes of a device may be determined by using both power monitoring and network monitoring.

A trailer monitoring system for monitoring a trailer having at least one trailer sensor has a bridge integrator unit, configured to couple with the trailer, including a wireless data transceiver electrically coupled with a microcontroller and capable of wirelessly communicating data over a short-range wireless protocol; the bridge integrator unit receives data existing in a first messaging format that is compatible with and used by one or more trailer sensors via a short-range wireless protocol, extracts the data, encodes the data into a second messaging format that is compatible with a master control unit having a telematic data transceiver capable of cellular data communications, and transmits the data in the second messaging format from the bridge integrator unit to the master control unit via a short-range wireless protocol.

According to some embodiments, a railcar monitoring system for monitoring one or more conditions associated with a railcar comprises a railcar controller and one or more sensors disposed throughout the railcar and communicably coupled to the railcar controller. The railcar controller is configured to exchange data with the one or more sensors and transmit data from the one or more sensors to a remote location. An amount of data exchanged between the railcar controller and the one or more sensors is controlled based on a railcar context. The railcar context is based on a location and/or activity associated with the railcar.
