System for wireless transmission of electrical power, a garment, a system of garments and method for the transmission of signals and/or electrical energy

A system as claimed in one of the above claims, in which means (38) for rectifying the induced voltage are provided in the secondary circuit (S).

A system as claimed in one of the above claims, in which

• controlled switching means (32, 38) are provided both in the primary circuit (P) and in the secondary circuit (S),
• in which the switching means (32, 38) can be triggered in such a way that they generate an AC voltage from a supplied DC voltage,
• and the switching means (32, 38), when triggered differently, work as synchronous rectifiers that rectify a supplied AC voltage.

A garment with

• an electrical circuit (46) with at least one connector (48, 50) for electrical connection of at least one electrical unit (62), characterized in that
• the connector (48, 50) transmits in a wireless manner electrical energy and/or electrical signals to a corresponding further connector (64) on the electrical unit (62) and/or receives this from the electrical unit (62).

A method for the transmission of signals and/or electrical energy from a first electrical unit to a second electrical unit, in which

• the electrical units (D1, D2, D3, D4, S) are arranged on at least one garment (91, 92, 93, 94),
• where at least a first electrical unit (D1, D2, D3, D4, S) has an inductive coupling with an electrical circuit of the garment,
• and via the inductive coupling electrical signals and/or electrical energy are transmitted from the first electrical unit (D1, D2, D3, D4, S) to another electrical unit (D1, D2, D3,D4).
