Embodiment Construction

[0052] The first embodiment is in figure 1 shown in . figure 1 One embodiment of a body-coupled communication system 190 comprising a first body-coupled communication device 100 and a second body-coupled communication device 180 is schematically shown. And, the first body-coupled communication device 100 and the second body-coupled communication device 180 are configured to transmit signals and data via the body transmission channel 160 formed by the body of the user 150 . The first body-coupled communication device 100 and the second body-coupled communication device 180 are able to communicate via the body transmission channel when the couplers of the respective devices are directly adjacent to the user's body. Direct proximity to the user's body means that the coupler and the body are within a maximum distance of each other allowing signal exchange via the user's body. Optionally, said maximum distance (of immediate neighbourhood) is closer than 10 cm or closer than 5 cm....

Abstract

A receiver module (101), transceiver module for body coupled communication devices (100) and a method of waking-up a body coupled receiver of a body coupled communication device (100) are provided. The receiver module (101) of the body coupled communication device (100) comprises couplers (102) for receiving signals via a body transmission channel (160) which follows a body of a user (150). A wake-up receiver (108) and a main receiver (106) of the receiver module (101) are coupled to the couplers (102). The main receiver (106) may operate in a sleep mode and in an operational mode. The wake-up receiver (108) generates a wake-up signal (107) when signals received via the body transmission channel (160) in a predefined spectral range exceed an energy threshold level. The wake-up signal (107) is provided to a circuitry of the body coupled communication device (100) to directly or indirectly configuring the main receiver (106) in the operational mode.

Description

technical field [0001] The invention relates to a receiver module, a transmitter module and a transceiver module for a body-coupled communication device. The invention further relates to a body-coupled communication device comprising a receiver module, a transmitter module and / or a transceiver module. The invention further relates to a method of waking up a body-coupled receiver of a body-coupled communication device. Background technique [0002] Body-Coupled Communication (BCC) allows the exchange of information between devices located, for example, at or near a user's body. Instead of via wires or instead of via radio signals, the BCC signal is transmitted via the body. The signal is transmitted via a low energy electric field that is capacitively or galvanically coupled onto the body surface. The low energy electric field is coupled to the body via couplers such as electrodes. Sometimes the term antenna is used in the BCC field to identify a coupler, however, in BCC ...
