from each other application_number US 200913142886 A description fig1 a shows an embodiment of an inventive device for the non contact actuating of a trunk lid 10 1 as a moving part 10 of a vehicle 1 constituting a motor vehicle the moving part 10 is held in the closed position and secured by an electromechanical lock 25 the device comprises a first detection means 11 for detecting an object 17 18 in a first detection area 11 a and a second detection means 12 for detecting an object in a second detection area 12 a the detection means 11 and 12 are configured as capacitance sensors 11 and 12 and only indicated schematically in the figure detection area 11 a covers the horizontal area behind the rear bumper 16 of the vehicle 1 on the other hand detection area 12 a covers the lower area beneath the rear bumper 16 thus a first detection area 11 a and a second detection area 12 a are created which are geometrically separated from one another and have no common area external of the rear bumper 16 the detection areas 11 a and 12 a are indicated by beams which however only indicate areas depicting a change in dielectric constant between the capacitance sensors 11 and 12 and the vicinity of the rear bumper 16 this change in dielectric constant causes a change to the charge storable on the electrodes of the capacitance sensors 11 and 12 which the device can detect thus the capacitance sensors 11 and 12 can furnish the presence.
