Publication number: 20230356341Abstract: The disclosure relates to a machine tool having a driveable tool and having a detection system for detecting contact between the tool and a user. The detection system has an excitation device for applying an excitation voltage signal to the tool, a current sensor for generating a current sensor signal that represents an electric current consumed by the tool, and a processing device for processing the current sensor signal in order to detect contact between the tool and the user. The processing device has an analog-to-digital converter and further devices arranged downstream of the analog-to-digital converter, comprising an IQ demodulator, a filter device and an evaluation device. The current sensor signal is able to be digitized using the analog-to-digital converter and processed in digital form using the further devices. The disclosure furthermore relates to a detection system for a machine tool.Type: ApplicationFiled: September 9, 2021Publication date: November 9, 2023Inventor: Dieter Volpert

Patent number: 10758989Abstract: A method for detection of a fault in a sensing cable within a saw detects potential failures in a sensing cable that is part of an object detection system in the saw. The method includes generating a predetermined excitation signal transmitted through a first conductor and a second conductor in the sensing cable, detecting a return signal from the first conductor and the second conductor in the sensing cable in response to the predetermined excitation signal, identifying a signal-to-noise ratio (SNR) of the return signal, and generating an output indicating a fault in the sensing cable in response to the SNR of the return signal being below a predetermined value.Type: GrantFiled: March 4, 2016Date of Patent: September 1, 2020Assignees: Robert Bosch Tool Corporation, Robert Bosch GmbHInventors: Dieter Volpert, Bharadwaja Maharshi Ramaswamy, Indumathi Chandrashekar, Ankur Mishra, Seenivasan Ayyamperumal, Eric Laliberte
