A seat assembly may include a seat, a biomedical sensor, a bladder assembly, a pulsed electromagnetic field (PEMF) coil assembly, and/or an electronic control unit (ECU) connected with the biomedical sensor. The ECU may be configured to control the bladder assembly and the PEMF coil assembly, and/or to determine if a user occupying the seat is in a first state or a second state. The first state may correspond to one or more small user movements. Small user movements may include movements having magnitudes below a specified value or threshold. The second state may correspond to one or more large user movements. Large user movements may include movements having magnitudes above the specified value or threshold. The ECU may operate in a first mode when said user is in the first state and operate in a second mode when said user is in the second state.

A vehicle seating assembly includes a seat base that has a first heating element. A seat back has a second heating element. A sensor is coupled to the seat base and is configured to obtain a weight data. A user-interface assembly is operably coupled to the first and second heating elements. A controller is in communication with the sensor to receive the weight data. The controller is configured to control the first and second heating elements in response to the weight data.

Energy management techniques for heating or cooling a surface of a component of a vehicle comprise determining a heating lag time indicative of a lag time for a surface element of the vehicle component to heat to a first target temperature in response to a power on-off or power off-on modulation of a heat transfer component, determining a cooling lag time indicative of a lag time for the surface element to cool to a second target temperature in response to a power on-off or power off-on modulation of the heat transfer component, and controlling power-on and power-off times of the heat transfer component based on the determined heating and cooling lag times so as to not require a temperature sensor for feedback-based temperature control.

A back panel of a motor vehicle seat includes, on its visible external back side, a thermal layer.

A comfort element for a vehicle includes an actuator for carrying out a comfort function, a comfort-element-internal store configured to drive the actuator and/or a coupling device for coupling to a comfort-element-external store configured to drive the actuator. The comfort element further includes a data interface for coupling to an operating unit.

A vehicle comprising a plurality of seats, a plurality of Bluetooth modules to which Bluetooth identification information, different from each other, is assigned, configured to perform pairing with a plurality of user terminals, wherein each of the plurality of Bluetooth modules corresponds to each of the plurality of seats, a memory configured to store terminal identification information assigned to each of the plurality of user terminals and the Bluetooth identification information assigned to each of the plurality of Bluetooth modules, and a processor configured to be connected to the plurality of Bluetooth modules and the memory.

An occupant support system includes a vehicle seat and an electronics system for the vehicle seat. The electronics system includes a sensor system configured to obtain sensor data and a computer coupled to the sensor system to process the sensor data and perform a predetermined action using the sensor data.

An embodiment relates to a heat transfer device including a heat generating device configured to generate heat having predetermined intensity by a user, a cover in contact with a body of the user while covering the heat generating device, and a heat transfer medium provided between the heat generating device and the cover to transfer the heat generated by the heat generating device, wherein the heat transfer medium is a structure that is formed by entangling a single wire having a predetermined length and has a predetermined width and a predetermined height, and is a structure that is compressed in an axial direction when being in contact with the body of the user and thus has a Poisson's ratio of 0.5 or higher. Thus, a structural change in the heat generating device is not required and only a material in contact with the heat generating device is changed, so that generated heat may more rapidly reach the body of the user.

A heating and cooling device is disclosed comprising at least one integral low voltage heating and cooling source and an efficient flexible heat distribution means having a thermal conductivity of from 375 to 4000 W/mK for distributing the heat and cool across a surface. Further aspects include thermal interface compounds to provide full thermal contact as well as the use of a phase change material to provide a long lasting heating and/or cooling effect without the use of external electrical input. Preferred applications include automotive and furniture seating heating and cooling, along with outdoor garments having distributed heating and cooling effects.

An electronic control unit for a heat-generating electrical device of a vehicle, that includes a microcontroller configured to control the operation of the heat-generating electrical device in dependence on a temperature signal of at least one temperature sensor thermally coupled with the heat-generating electrical device; and at least one electronic thermal protection circuit configured to at least temporarily interrupt the control of the operation of the heat-generating electrical device in dependence on the temperature signal of the at least one temperature sensor thermally coupled with the heat-generating electrical device.
