The invention relates to the use of the modulation of an audio and/or visual signal by a variation in the impedance of at least one contact with the skin of at least one user, for the maintenance and/or development of the user's physical and/or mental abilities. The invention comprises the use of a device (100) for controlling the delivery of a medium, said device comprising: a first skin electrode (105) configured to generate electric waves, positioned against the skin of a first user; a second skin electrode (110) configured to capture electric waves, positioned against the skin of a second user, where the second user can be the first user; a detector (115) for detecting the value of an impedance parameter of the junction connecting the electrodes and passing through the contact with the skin of each user; and a control means (120) configured to transmit a medium-delivery command according to the value detected.

An electronic device and a method of grip recognition of the electronic device are provided. The electronic device includes an antenna; a radio communication unit having a coupler; a memory; and a processor which is operatively connected to the radio communication unit and the memory. The memory comprises instructions, executable by the processor. The processor is configured to detect a first signal being transmitted and a second signal being received through the antenna using the coupler, calculate a reflection coefficient of the antenna based on the first signal and the second signal, determine at least one of a signal magnitude or a phase corresponding to the reflection coefficient, and determine whether the electronic device is being gripped based on the at least one of the signal magnitude or the phase.

A remote three-way switch. The remote three-way switch includes an actuator configured to actuate a mechanical switch, such as a light switch, according to a signal received from a remote control in wireless communication with the actuator. The signal received directs the actuator to mechanically actuate the switch from an on position to an off position, or from the off position to the on position. The remote three-way switch is portable, easy to install and uninstall, and is configured to assist an individual with operating the switch from a distance. The remote three-way switch may also be configured to be permanently installed into a wall, such that it appears like an ordinary light switch after installation.
