  • Thermally controlled electronic device
    Patent number: 10367498
    Abstract: An electronic device includes at least one electronic component, a gradient heat-flux sensor GHFS based on thermoelectric anisotropy and conducting heat generated by the electronic component, and a controller adapted to manage electrical current of the electronic component at least partly on the basis of an electrical control signal generated by the gradient heat-flux sensor and proportional to a heat-flux through the gradient heat-flux sensor. Therefore, the electrical current and thereby also the heat generation of the electronic component are managed directly on the basis of the heat-flux generated by the electronic component. Thus, the electrical current can be managed without a need for voltage and current measurements which may be challenging to be carried out with a sufficient bandwidth especially when the switching frequency of the electronic component is on a range from hundreds of kHz to few MHz.

  • Thermal power measurement
    Patent number: 10060363
    Abstract: There can be provided an engine control apparatus having a controller operable to receive input from a heat flux sensor arranged to measure combustion power within an internal combustion engine and to use said input in a control process to determine an adjustment to a controllable engine operation parameter.
