The invention relates to a receptacle for storage of an object, containing a proximity sensor capable of detecting an action by a user close to or in contact with a surface of the receptacle, a transducer and a control circuit comprising an input coupled to the proximity sensor and an output connected to the transducer, the control circuit being configured to generate a control signal to be sent to the transducer when a user action is detected by the proximity sensor, characterized in that it also comprises an unpacking detector coupled to the control circuit and in that the control circuit is also configured to changeover from a standby mode during which it periodically awakens to query the unpacking detector, to a detection mode during which it periodically checks the state of its input coupled to the proximity sensor, after the unpacking detector has detected removal of the receptacle from a packaging.

Receptacle interacting with a user with reduced energy consumption before unpacking

A vessel for storing an object, comprising an electrically insulating container, intended to contain the object and an electrically conductive layer, arranged on a surface of the container. There is a control circuit including an electrically conductive detection element, electrically insulated from the conductive layer and capacitively coupled to the conductive layer. The control circuit is configured to measure the capacitance formed between the conductive layer and an electrically charged object brought close to the conductive layer and to generate a control signal dependent on the measured capacitance.

A method and system for measuring the output power produced in a device having a crankset, includes: measuring the orthogonal force exerted on at least one pedal of the crank; determining the angular velocity of the crank; and deducing the tangential force exerted on the crank and the power, using a pre-established model of the distribution of the force exerted on the actuating member as a function of the angular velocity.

A method for displaying an image onto a relief projection surface using a projection system includes the automatic measurement, using a fixed camera, of the distance separating virtual reference frame points projected onto the projection surface, from real reference frame points produced on a three-dimensional screen to set the projection system, acquisition, by the same fixed camera as that used during the setting of the projection system, of an image of a rear face of the three-dimensional screen, identification of the position of a finger in contact with a front face of the three-dimensional screen in the acquired image, and control of an appliance according to the identified position of the finger.
