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.

Recipient for storing a fluid intended to interact with a user

An apparatus for etching a pattern in an etching zone laid out on a substrate includes a pen that can be freely moved manually relative to the etching zone, the pen being equipped with an etching head able to etch the substrate at an etching point when etching is triggered, a measuring unit for measuring position and orientation of the etching head relative to the substrate, a control unit configured to calculate coordinates of the etching point as a function of the measured position and orientation of the etching head relative to the substrate, to trigger etching at the etching point if the calculated coordinates of the etching point correspond to coordinates of a point to be etched, the coordinates of the point to be etched being encoded in a prerecorded drawing of the pattern, and to automatically prevent etching otherwise.

Device and method for etching a pattern

The invention relates to a portable device for printing an image in a printing area provided on a material substrate, which includes: at least one removable benchmark (-) capable of being manually positioned on the substrate and associated with a corresponding point of the image being printed by means of a predefined relationship separate from the position of said benchmark on the substrate, a measurement unit capable of measuring the position of the printing head relative to the benchmark, and a control unit () capable of determining the distance separating the pen from the substrate, from the measurement of the position of the printing head, and of preventing the image from being printed on the substrate if said distance is greater than a predetermined threshold.
