Abstract: The present disclosure relates to a computing unit for securely performing an operation on encrypted data in an Internet of Things, IoT, environment. The computing unit comprises a secure element, at least one processor and at least one memory, wherein the at least one memory contains instructions executable by the at least one processor such that the computing unit is operable to obtain (S302) encrypted data collected by a sensor provided in the IoT environment, pass (S304) the encrypted data to the secure element requesting the secure element to decrypt the encrypted data and to perform an operation on the decrypted data, and obtain (S306) an encrypted or non-encrypted result of the operation from the secure element.

Abstract: An auxiliary device for conductively removing the heat produced by one or more components on an electronic card includes a heat sink covering all or part of the card. The device includes at least a first heat-conducting element mounted to absorb the heat produced by the one or more components, a movable second heat-conducting element, a heat pipe connecting the first element with the second element, and clamping means designed to press the movable second element against a cold wall.

Abstract: The present invention relates to a device for preheating a component cooled by conduction and/or by convection. The component is in contact with a heat conductor and the device includes a heater to heat the part, the device further including at least one heat pipe having fluid within, to connect a heat dissipater with the heat conductor, the dissipater and the part furthermore being thermally insulated from one another. Freezing of fluid in the heat pipe facilitates preheating of the component at low temperature. The invention applies notably to the starting of components subjected to low temperatures, for example, components installed in systems on board aircraft.
