A detection device coupled to an item includes a sensor configured to detect user interaction with the item and transmit a signal related to the user interaction and the item. A processor of the detection device receives the signal and determines a type of the user interaction and information about the item based on the signal. The detection device is configured to transmit a signal indicating the type of the user interaction and the information about the item. A server is configured to receive the signal (e.g., from the detection device or a HUB) and determine a user interaction profile associated with the item. The user interaction profile can indicate data about one or more users' interaction with the item or data about the item. The server is also configured to output data indicating the user interaction profile via a graphical user interface or store the data.

A distributed sensor network that utilizes the cabling infrastructure installed for a Distributed Antenna System (DAS) to collect environmental data about a building. In this sensor network, an array of sensors are placed in line with the DAS communication cabling so that additional cabling is not required. The sensors use out of band frequencies or low level signaling so as to not interfere with the DAS signals to communicate the sensor data to the DAS head-unit.

Example methods, apparatuses and systems are disclosed for monitoring and tracking goods flowing through a supply chain. In this regard, goods may be associated with one or more monitoring nodes for monitoring various parameters such as conditions associated with an environment of the goods. In this regard, the monitoring nodes transmits telemetry data monitored by the monitoring nodes, via edge devices or gateway nodes to a server. In accordance with various embodiments illustrated herein, based on an analysis of status information and a network connection quality, associated with transmission of telemetry data packets over a communication network, the data packets under transmission, may be altered by processing the data packets locally and intermediately at the edge devices before sending to the server. The data packets may be altered such that, in an operation, only a portion of data packet including relevant contextual information associated with the telemetry data may be transmitted to the server.

The device includes: an acquisition module arranged to acquire target resource information, a notification sending policy and a notification sending address; a generation module arranged to generate a corresponding notification message when a target resource changes; and a sending module arranged to send the notification message to the notification sending address according to the notification sending policy.

The present invention is related with a modem device in conjunction with a Low Power Controller, which provides the capability of local control and remote management of electromechanical appliances in cases, where the locally available electric power is very low, and it is specially designed to be electrically powered and to communicate via a single PSTN telephone line The device has a wide application range to institutions, which own and use areas containing both passive and active equipment, and provides the capability of a single uniform solution for all such cases. It provides the ability to connect various digital and analog sensors, the transmission of various commands, the process automation, the data and information collection and the remote control (management).

Embodiments of the invention provide methods and apparatuses for implementing telemetry applications with the SIM card of a mobile equipment. For one embodiment of the invention the telemetry application allows the encoding of TAD within a supplementary services message and transmission of the TAD over a control channel of a GMS telecommunications system. For one embodiment of the invention the telemetry application allows the decoding of caller identification message received from a CMS to obtain the TAD.

A method and system for elastic timestamping for use in computing and networking applications including telemetry is disclosed herein. A device that is part of a system may initially generate a variable size timestamp or elastic n-dimensional timestamp (ENTS) with n time dimensions fields for a corresponding event in the system for which timing or temporal order information is needed. The device may select a subset of the n time dimensions fields of the ENTS based on a relevant time granularity of the corresponding event to generate a compact ENTS with a reduced size. The device may communicate the compact ENTS for further processing. In an example, the ENTS may be generated for a device-specific action performed to gather telemetry data in response to received telemetry intent at the device, and the compact ENTS may be communicated with a corresponding telemetry response.

A method and system for flow tracing for use in a packet-optical network is disclosed herein. A device in the packet-optical network may receive a packet including a header and payload. The device may read intent information from the header, and translate the intent information to generate a device-specific action in an optical layer to provide one or more globally unique identifiers (IDs) associated with the device. The device may execute the device-specific action in the optical layer to generate a response including the globally unique IDs corresponding to the intent, where the response forms part of the flow trace. The device may associate the response with the intent, and encode the response for downstream data forwarding. The device may further add multi-layer proof-of-transit (POT) information to the response that may be used to securely verify the path indicated in the SmartFlow flow trace.

A method and system for packet-optical in-band telemetry (POINT) that may be used in a packet-optical network is disclosed herein. An intermediate POINT device may receive a packet including at least a header and a payload at a packet layer. The POINT device may read intent information from the header, and the intent information may indicate a type of telemetry data to be collected. The POINT device may translate the intent information from the packet layer to generate a device-specific action in an optical layer to the type of telemetry data indicated by the intent. The POINT device may execute the device-specific action in the optical layer to generate a response corresponding to the intent, associate the response with the intent, and encode the response in the packet layer for downstream data forwarding.

A system and methods for reliable telemetry are disclosed herein. In an example of reliable in-band telemetry in a communications network, intent information for a destination device may be generated at a network device indicating a type of telemetry data to be collected. The network device may update a locally stored invertible Bloom function (IBF) by applying one or more hash function to the intent information, a destination identifier (ID) associated with the destination device, and/or a local timestamp, and periodically forward the locally stored IBF to the destination device. The network device may receive a notification message by the destination device that the intent information is missing at the destination device and re-forward the intent information to the destination device. In another example, a network device may maintain and periodically forward a locally stored IBF based on response data and the destination ID.
