Publication number: 20230283880Abstract: A process and an image evaluation system are provided with a mobile sensor arrangement, including a camera (IR), a motion sensor (IMU), and a receiver (Komm), that is moved through a spatial area. The camera generates an image sequence. The motion sensor generates an orientation signal with camera viewing direction in a predefined three-dimensional coordinate system when generating an image. A signal processing unit (Sv) checks whether the receiver is receiving a signal from a transmitter (UWB.1, UWB.2, UWB.3) of a transmitter group. If the receiver receives a signal, the signal processing unit determines the distance between the transmitter and the receiver. A classifier (Kl) searches for images of humans in images of the image sequence. The signal processing unit decides whether an image of a human shows a person associated with a transmitter of the transmitter group and may generate a trajectory describing the movement of the camera.Type: ApplicationFiled: March 1, 2023Publication date: September 7, 2023Inventors: Livio FORNASIERO, Folke WILL

Patent number: 11331011Abstract: A system, for the transcutaneous measurement of a substance concentration, preferably alcohol, in blood, includes a light source (1); a detector device (15); an optical device (7, 7?), with an inlet (5), an outlet (49) and an exit opening (35); and a contact surface element (37) with a contact surface (41). Measuring radiation emitted by the light source (1) reaches the inlet (5) and exits the exit opening (35), to the contact surface (41). The optical device (7, 7?) focuses measuring radiation at a measuring point (39) at a predefined distance from the contact surface (41). The optical device (7, 7?) is configured such that scattered radiation generated in the measuring point (39) and entering into the exit opening (35) is focused at an outlet point (19) at the outlet (49). The detector device (15) is arranged to detect the scattered radiation focused at the outlet point (19).Type: GrantFiled: September 24, 2015Date of Patent: May 17, 2022Assignee: Dräger Safety AG & Co.

Patent number: 10614695Abstract: A gas-measuring device includes a control unit, a gas sensor module, a radio receiver unit, a first radio transmitter unit and a second radio transmitter unit. The control unit detects sensor data via the gas sensor module in a first operating state and upon detecting a potential hazardous state, based on the sensor data, changes over into a second operating state. The control unit further detects one or more radio signals, which indicate respective characteristics of respective portable transmitter units, by the radio receiver unit in the second operating state, and determines, on the basis of the radio signals, which of the transmitter units have a sufficiently close proximity in space to the gas-measuring device. The control unit provides the characteristics of the transmitter units, having a sufficiently close proximity in space, via the first radio transmitter unit.Type: GrantFiled: December 17, 2018Date of Patent: April 7, 2020Assignee: DRÄGER SAFETY AG & CO.
