A programmable controller stores operational data for a number of embedded functions in multiple OEM vehicles and is programmable to operation in a selected vehicle among the multiple vehicles.

A system and method are provided for automated engaging of a truck trailer at a loading dock. Sensors measure a distance and an angle of alignment between the incoming trailer and a wall of the loading dock. An outside lighting system guides a truck driver backing the trailer toward the dock door. A vehicle restraint system fixates the trailer within the loading dock in response to signals from the sensors. An overhead dock door opens once the trailer is successfully fixated by the vehicle restraint system. A dock leveler deploys after the overhead dock door opens. An inside dock light indicates to dock personnel that the trailer is ready to be serviced. Once servicing of the trailer is finished, an automated release of the trailer from the loading dock may be initiated by PLC communication.

An air conditioner current loop communication circuit includes an indoor unit current loop communication circuit and an outdoor unit current loop communication circuit connected to each other via a communication connection wire and an AC power connection wire to form a current loop communication loop, an indoor microcontroller unit (MCU) and an outdoor MCU configured to communicate with each other through the current loop communication loop, and a switching power supply circuit connected in series to the communication connection wire or the AC power connection wire and configured to output a DC power to the current loop communication loop.

Described herein are systems for mode switching in an appliance, and related analysis and reporting. Associated methods can include determining, by circuitry of an appliance, that an operation of the appliance is abnormal. The determination can include sensing the abnormality and identifying that the operation of the appliance is an abnormal operation according to the sensing of the abnormality. The methods also include switching, by the circuitry, the operation of the appliance to a safe mode. The safe mode can include reducing power used with the operation (such as to stop or reduce speed of rotation of a fan in the appliance). The method also includes communicating, by the circuitry, information regarding the abnormality and/or that the abnormality was resolved, to an electronic device and/or a server. The electronic device can display the information on a display device. The server can generate statistics according to the information.

A technique for energy sample forecasting of heating, venting and air conditioning-refrigeration (HVAC-R) systems is disclosed. In an example, a first expected energy sample of a HVAC-R system at a first time period is forecasted by modelling actual energy samples of the HVAC-R system at previous time periods using a statistically-based seasonal-autoregressive integrated moving average (SARIMA) model. Further, an anomaly is detected at the first time period when deviation between the first expected energy sample and an actual energy sample at the first time period is greater than a dynamic context sensitive threshold. Also, an expected energy sample at next time period is forecasted by modelling a second expected energy sample of the HVAC-R system at the first time period using the statistically-based SARIMA model upon detecting anomaly. The second expected energy sample is forecasted by modelling the actual energy samples at the previous time periods using a physical model.

An air conditioning device is provided. The air conditioning device includes: a sensor configured to sense a driving state of the air conditioning device and ambient air information of the air conditioning device; a processor configured to calculate temperature and humidity information of discharged air on the basis of the information sensed by the sensor, and calculate an amount of dehumidification on the basis of the calculated temperature and humidity information; and a display configured to provide the calculated amount of dehumidification.

A vehicle management system includes an onboard vehicle system and a ground system. The onboard vehicle system includes a compressor exit temperature sensor configured to determine an ECS compressor exit temperature; a data acquisition unit coupled to receive the compressor exit temperature, an altitude of the first vehicle, and an ambient temperature and configured to generate a data report; and a communications system coupled to receive and transmit the data report. The ground system includes a ground data server coupled to receive the data report and determine a fouling condition of an environmental conditioning element of the ECS based on at least the compressor exit temperature, the altitude, and the ambient temperature; and a mobile application module coupled to receive the fouling condition from the ground data server and configured to provide an interface for displaying the fouling condition to a user on a mobile device.

A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.

The techniques disclosed herein enable utilizing a full range of setpoint values to control a mechanical system. A machine learning model is trained with states collected from the mechanical system. Some of the states may have little to no variation, limiting exploration of possible setpoint values when training the model. To enable a more thorough exploration of possible setpoint values, the states are augmented with a fluctuating delta value that is derived from a fixed setpoint value. For example, a delta outside air temperature may be computed by subtracting outside air temperature, which fluctuates, from a fixed chilled water setpoint. A method of moments computation converts delta values inferred by the model back into absolute values. The absolute values are used to compute a regression equation that is usable by the mechanical system to compute a setpoint action for a given set of input states.

Reinforcement straps are used to hold a mattress system in place and keep it from bowing outwards when used. The mattress system can include a layer and a rail structure attached to the layer. The layer can have a layer top and a layer bottom opposite to the layer top. The layer can extend between a first layer edge and a second layer edge.
