Patent number: 11928809Abstract: A device for generating an image of an object by electromagnetic waves has a transmission device which is set up to radiate electromagnetic waves in the direction of the object, a receiving device which is set up to receive electromagnetic waves from the object, and a digital processing and control unit which is set up to generate image data of the object from the measured data. Here, the transmission device and the receiving device are arranged in at least one modular unit. The digital processing and control unit has an interface via which different modular units can be exchangeably coupled to the digital processing and control unit. Here, the interface is set up to transmit data to the modular unit and to receive from this, to transmit control signals to the transmission device and to the receiving device, and to supply the modular unit with energy.Type: GrantFiled: November 15, 2021Date of Patent: March 12, 2024Assignee: Balluff GmbHInventor: Mark Eberspaecher

Patent number: 11573288Abstract: A multi-field zone proximity sensor (10) for measuring a distance (1) of an object (22) from the multi-field zone proximity sensor (10) The multi-field zone proximity sensor (10) has a housing (12) that includes an antenna structure (14) that is arranged in or close to a side (19) of the housing (12). The antenna structure (14) is set up for emitting an electromagnetic transmission free space wave (20) and for receiving an electromagnetic reflection wave (24) reflected on the object (22). The multi-field zone proximity sensor (10) has sensor electronics (16) which are set up to determine the distance (l) of the object (22) from the multi-field zone proximity sensor (10) based on the received reflection wave (24).Type: GrantFiled: July 12, 2019Date of Patent: February 7, 2023Assignee: BALLUFF GMBHInventors: Mark Eberspaecher, Attila Szabo

Patent number: 10598777Abstract: A proximity sensor for measuring the distance from a target contains a microwave oscillator providing a transmission wave output signal emitted toward the target as a free space transmission wave which is reflected by an electrically conductive target surface as a free space reflection wave received by the proximity sensor as a reflection wave. The distance is determined from the transmission wave and the reflection wave. The transmission wave is guided in a waveguide transmission path as a waveguide transmission wave. The transmission wave is coupled into the waveguide with a wave mode leading to the detachment of the waveguide transmission wave at the waveguide front end aperture into the free space transmission wave and to the propagation of the free space transmission wave to the target. At least one reception path is electromagnetically decoupled from the transmission path and guides the reflection wave as a waveguide reflection wave.Type: GrantFiled: December 23, 2014Date of Patent: March 24, 2020Assignee: Balluff GmbHInventors: Mark Eberspaecher, Sorin Fericean

Patent number: 10534077Abstract: A proximity sensor measures the distance of a target and a method operates the proximity sensor. The proximity sensor emits a transmission signal as a free-field transmission wave, which is reflected at the target and as a free-field reflection signal is received by the proximity sensor as a reflection signal, wherein the determining of the distance is provided from the phasing of the reflection signal in relation to the phasing of the transmission signal. The proximity sensor shifts the phasing of the transmission signal chronologically.Type: GrantFiled: March 6, 2015Date of Patent: January 14, 2020Assignee: Balluff GmbHInventors: Sorin Fericean, Mark Eberspaecher

Patent number: 10132922Abstract: A proximity sensor for measuring the distance from an object contains a microwave oscillator providing, as an output signal, a transmission wave emitted toward the object as a free space transmission wave reflected by the object, the object being electrically conductive or having at least one electrically conductive surface, as a free space reflection wave and is received by the proximity sensor as a reflection wave. The reflection coefficient is determined from the transmission and reflection waves and is provided by the proximity sensor as a measure of the distance. The transmission wave is guided in a waveguide as a waveguide transmission wave and is injected into the waveguide with a wave mode which results in the waveguide transmission wave being separated at the aperture at the front end of the waveguide into the free space transmission wave and in the free space transmission wave propagating to the object.Type: GrantFiled: July 1, 2013Date of Patent: November 20, 2018Assignee: Balluff GmbHInventors: Sorin Fericean, Mark Eberspaecher
