Abstract: Beam-shaping laser optics are provided with a lens field (28) which comprises a plurality of first lenses (32) which are configured and arranged next to one another such that the plurality of first lenses (32) effect a beam shaping in a first direction (y) normal to an optical axis (x), as well as with an individual second lens (30) which is configured such that the individual second lens (30) effects a beam shaping in a second direction (z) normal to the optical axis as well (x) as well as the first direction (y). The lens field (28) and the second lens (30) are arranged in a beam path (12) one after the other along the optical axis (x). A laser system is provided with such beam optics.

Abstract: A ventilation control unit (100), regulating a gas flow (102) within a ventilation system (105), includes a reception module (120), first and second calculation modules (130, 135) and an output module (140). The reception module has a signal interface (122) receiving inspiratory and expiratory flow signals (125, 127) at regular time intervals. The first calculation module calculates a leak flow (132) based on a difference between the current inspiratory gas flow and the current expiratory gas flow, with an external gas flow source (110) separated from a ventilation circuit of the ventilation system. The second calculation module calculates an external gas flow (136) after connecting the external gas flow source to the ventilation circuit based on the leak flow and the difference between the current inspiratory gas flow and the current expiratory gas flow. The output module outputs an output signal (142), based on the external gas flow.

Abstract: A battery-powered stationary measuring device, measuring or detecting a utility installation value, includes a Low Power Wide Area Network (LPWAN) connection module configured to establish a wireless communication connection to a LPWAN for communicating data to a head-end-system (HES) and attempt to successfully establish a connection to the LPWAN by selectively conducting one of the group comprising: an extended LPWAN search and a limited LPWAN search; veto the extended LPWAN search as long as a savings threshold for a total number or amount of power budget savings has not been reached; increase the total of power budget savings for unsuccessful limited LPWAN searches; and allow the extended LPWAN search if the total number or amount of power budget savings has reached the savings threshold. The total number or total amount of power budget savings is reduced with each conducted extended LPWAN search.

Abstract: A pump assembly with a pump unit comprising an impeller for pumping fluid, an electric motor for driving the impeller, a control module for controlling the speed of the electric motor in a control mode, and an interface for receiving a pulse width modulated (PWM) control signal with a duty cycle indicative of the speed of the electric motor. The control module is configured to interpret the PWM control signal at start-up of the electric motor per default in a configuration mode as a configuration bit sequence based on the duty cycle of the PWM control signal during a pre-determined configuration window.

Abstract: A parking brake includes an inhibitor device (31), which can be associated with a drive shaft (3) for rotating therewith, the inhibitor device (31) being actuated by centrifugal force. The parking brake further includes a locking member (33) adapted to engage the inhibitor device (31) when actuated. The inhibitor device (31) is configured to prevent the engagement of the locking member with the inhibitor device when the inhibitor device rotates at a speed greater than a minimum speed, so as to prevent the application of the parking brake.
