  • Publication number: 20250058289
    Abstract: A mixing device for mixing a powder-liquid mixture, comprises a movable body, arranged within the housing, with a channel formed between the housing and the movable body. An actuator moves the movable body between a closed and an opened position. The movable body comprises a first body section having a first set of openings, and a second body section having a second set of openings. The housing comprises a sleeve with a covering section that covers the second set of openings when the movable body is in the closed position, for minimizing a flow of the mixture through the second set of openings, and be offset from the second set of openings when the movable body is in the open position, for allowing the mixture to flow into the channel through the second set of openings.

  • Publication number: 20240357725
    Abstract: The invention relates to a module (1a) for a luminaire. The module (1a) comprises a processing unit (2a) and a transmitter (3a) for wireless communication. The module (1a) may be electrically connected with a bus of the luminaire. In response to an event and/or a command of the luminaire, the processing unit (2a) is configured to control the transmitter (3a) to transmit a data packet (6), when the module (1a) is electrically connected with the bus of the luminaire. The data packet (6) comprises information on the event and/or the command of the luminaire in association with an address of the luminaire and a packet number; wherein the packet number is incremented by a number, optionally by one, each time the processing unit (2a) controls the transmitter (3a) to transmit the data packet (6). The invention relates to a further module, a luminaire and a system comprising the module and the further module.

  • Patent number: 12060986
    Abstract: The invention relates to a luminaire (10) comprising illuminants (170) for generating light, and a control unit (110) for controlling the illuminants (170), and at least one further element (140), in particular an operator control element (143) or a sensor (142), for generating control information that influences the operation of the luminaire (10), wherein the control unit (110) is configured in such a way that a self-test is carried out after a supply voltage has been applied to the luminaire (10). Said self-test is carried out automatically and independently in an analysis mode of the luminaire (10), wherein the control unit (110) checks the luminaire (10) for the presence and/or the functionality of the at least one further element (140). Depending on the checking result, and the type of further unit (140) checked, the control unit (110) controls the illuminants (170) such that a temporally variable light emission (171) signals the checking result.

  • Patent number: 11242787
    Abstract: Selective catalytic reduction systems are known and are generally included in exhaust systems of diesel engines in order to treat the exhaust gases of such engines. Such systems involve the introduction of diesel exhaust fluid (DEF) into exhaust gas flowing in an exhaust passage of an engine. When dosing DEF onto a hydrolysis catalyst in a SCR system, the DEF will under certain conditions cool the hydrolysis catalyst sufficiently to either slow down or effectively prevent ammonia release, which creates a lag or delay in the function of the hydrolysis catalyst. This limits the amount of control which can be exerted over ammonia storage in the SCR catalyst, and NOx conversion. In a first step, a set of measurement data is received from one or more sensors provided in the system.

  • Patent number: 11095031
    Abstract: An ultra wide band (UWB) antenna includes: (i) an array of antenna elements spaced from a central axis; and (ii) a network of lossy feedlines respectively communicatively coupled to the array of antenna elements. Each lossy feedline is periodically loaded with a resistance that is capacitively coupled to ground. Respective lengths of each lossy feedlines are selected to increase with an increase in distance from the central axis to achieve frequency independence of a radiated beamwidth from the UWB antenna.
