Abstract

A wrist computer to be worn on an arm of a user, comprising a detection device configured to detect at least one vital parameter of the user, and a radio module configured to, when activated, establish and maintain a wireless data connection to a radio module of another object, wherein the wrist computer comprises a control unit configured to activate the radio module of the wrist computer when the at least one vital parameter of the user is detected by the detection device, and to deactivate the radio module of the wrist computer when the at least one vital parameter of the user is no longer detected by the detection device.

Claims

1. An access system for a motor vehicle, comprising:

a wrist computer to be worn on an arm of a user, comprising;

a detection device, configured to;

detect at least one vital parameter of the user;

a radio module, configured to;

when activated, establish and maintain a wireless data connection to a radio module of another object;

a control unit, configured to;

activate the radio module of the wrist computer when the at least one vital parameter of the user is detected by the detection device; and

deactivate the radio module of the wrist computer when the at least one vital parameter of the user is no longer detected by the detection device;

a locking device of the motor vehicle for locking and unlocking the motor vehicle;

a radio module of the motor vehicle; and

a biometric access device of the motor vehicle, configured to;

actuate the locking device of the motor vehicle for locking or unlocking the motor vehicle when a predefined biometric feature of a person has been detected by the biometric access device and a user identification associated with the person has been transmitted to the radio module of the motor vehicle by way of the radio module of the wrist computer via the wireless data connection.

2. The access system of claim 1, wherein the biometric access device comprises a hand vein scanner.

3. The access system of claim 1, wherein the detection device comprises a pulse sensor configured to detect a pulse of the user.

4. The access system of claim 1, wherein the detection device comprises a temperature sensor configured to detect a skin temperature of the user.

5. The access system of claim 1, wherein the radio module of the wrist computer is configured to establish and maintain the wireless data connection via a Bluetooth connection.

6. The access system of claim 1, wherein the radio module of the wrist computer is configured to transmit the user identification via the wireless data connection to the radio module of the motor vehicle.
