The disclosure is provided to transmit a sensor value from a sensor to an external device with high efficiency. A sensor value of a sensor is acquired, basic data as time-series data is generated with reference to the acquired sensor value, differential data indicating a difference between the basic data and measurement data as time-series data corresponding to the sensor value acquired from the sensor is generated, and the differential data is transmitted to an external device through wireless communication.

An actuator control system includes: a transmission control unit configured to transmit final data, which is a final result of the computation by a sensor output computation unit, and to transmit intermediate data before transmitting the final data; and a command value computation unit configured to compute a command value for driving an actuator, based on the intermediate data and the final data transmitted by the transmission control unit.

Method and an arrangement for monitoring status of a production device configured to implement an industrial process or industrial production with a control device with sensors and actuators, where at least one further sensor is carried through the production device with a product being processed by the production device, where further signals are wirelessly transmitted to a status-monitoring device by the further sensor, and where the signals and/or status information items and the further signals are placeable in relationship with one another to generate status information item about the production device such that it is possible to plan the status monitoring separately from the production device, and possible to combine information items of the industrial control device with the information items and data of a mobile sensor (further sensor) that passes through the production device, such that more precise status information items about the production device status can be acquired.

Systems and methods are provided and include a variable frequency drive configured to drive a fan motor of an HVAC system to ventilate an indoor space, the HVAC system having a cooling assembly that includes at least one of an economizer and a compressor. A controller is configured to communicate with the variable frequency drive, receive at least one signal from an occupancy sensing device, determine whether the indoor space is less than fully occupied based on the at least one signal, and control the variable frequency drive to reduce a speed of the fan motor in response to determining that the indoor space is less than fully occupied.

An energy-reducing method and apparatus for retrofitting a single zone, constant volume HVAC system, with or without an economizer, that provides heating, cooling, and ventilation to occupants within a building space. The present invention includes the introduction of a programmable logic controller and variable frequency drive (VFD) that takes control of the existing fan, heating, cooling, and optional economizer operation. The reduction of the fan speed in the ventilation mode when the 100% operation is not needed saves significant energy of the existing constant volume HVAC system where the fan motor is designed to run 100% of the time.

A PLC system includes a displacement sensor, drives, and a PLC. The PLC system obtains line measurement data including a plurality of pieces of measurement information (1D information) from the displacement sensor and a plurality of pieces of positional information from the drives that are read in accordance with a measurement range and a measurement interval (measurement recording position) defined by the PLC for measuring an object A, and generates 2D shape data.

A method of synchronizing includes providing a sensor network including sensor nodes having object recognition sensors (ORS's) and building automation network nodes. The ORS's have partially overlapping fields of view in a sensed overlap area in the building. Movement of an individual through the sensed overlap area triggers dynamic synchronizing with the first sensor node waking up and sending a first RF request to join a subnet and for a schedule of wakeup times, the first sensor node receiving a response from any sensor node that receives the first request including synchronization information having times the first sensor node should wake up. The second sensor node is activated by the individual's movement and sends a second RF message to join the subnet and for a schedule of wakeup times. The first sensor node receives the second RF message and in response sends the synchronization information to the second sensor node.

A living-physics measurement and control system integrates a sensor array, analog front-end, controller module, and feedback actuator network to enable real-time quantification and modulation of energetic organization in open systems. The sensor array comprises thermal, mechanical/vibration, electrical/ionic, and optical sensors, providing multimodal data to the firmware and signal-processing unit. The controller module executes a coherence and entropy feedback control method, which includes system calibration, acquisition of synchronized sensor data, computation of order metrics such as coherence, entropy production, and information flux, and evaluation of energetic organization state. The feedback actuator network, including thermal actuators, mechanical actuators, ionic pumps, and optical emitters, receives actuator command set to dynamically adjust energy flow. The system generates quantitative metrics linking coherence, entropy, and information flow, enabling adaptive feedback to preserve or optimize functional order. The invention addresses the lack of integrated instrumentation and feedback for self-organizing, regenerative stability in open systems.
