Analogue regenerative transponders including regenerative transponder systems
First Claim
1. Transponder for amplification of a received signal (60) into a receiving element (1), e.g. an antenna, to a signal (61) for retransmission, where the retransmission signal (61) possible can have information superimposed, characterized in that the transponder comprises, as an amplifying element, a quenched oscillator (5).

Abstract
In a transponder (19) for amplification of a received signal (60) into an antenna (1), to a signal (61) for retransmission, and where the retransmitted signal (61) possibly may have information superimposed, a quenched oscillator (5) is incorporated as amplifying element. The oscillator (5) is preferably of superregenerative type and exhibits negative resistance (30) for the received signal (60). Transponders according to the present invention may be introduced as system elements in a wireless or wire based network to work as intelligent or unintelligent connections in the network. The transponders can also be used in positioning systems.

- 33. Transponder system for wireless and wire-based networks, comprising a number of transponders (19, 601, 606, 213, 219) for amplification of a received signal (60) into a receiving element (1, 141, 143, 200, 220, 223), for instance an antenna or a probe, to a signal (61) for retransmission, where the retransmitted signal (61) may have information superimposed, whereby the transponders can work as intelligent or unintelligent connections in a network based on transmission through at least one of a number of possible transmission media (92, 400, 460), characterized in that each transponder comprises, as amplifying element, a quenched oscillator (5, 355).
