Steffen Bachmaier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9161409
    Abstract: An illumination apparatus having a first illumination unit and a second illumination unit is provided. Each illumination unit has an LED arrangement and a supply device. Each LED arrangement has at least one LED group having a multiplicity of LEDs. A control device for driving the at least two illumination units with a common nominal dim drive value is included. The nominal dim drive value drives the illumination units in such a way that the similar LED groups of the illumination units are operated in a dim mode. The apparatus also has an offset device, which is formed to derive an absolute dim drive value for each of the similar LED groups from the nominal dim drive value with an offset value. The offset value is selectively assigned to the LED group and selected, such that the LED group is activated by the absolute dim drive value.

  • Publication number: 20140001953
    Abstract: The invention relates to an illumination apparatus having at least a first and a second illumination unit, wherein each of the illumination units comprises an LED arrangement and a supply device for supplying the LED arrangement, each of the LED arrangements comprising at least one LED group having a multiplicity of LEDs and the LED groups of the LED arrangements being similar, and having a control device for driving the at least two illumination units with a common nominal dim drive value, the nominal dim drive value driving the illumination units in such a way that the similar LED groups of the illumination units are operated in a dim mode. The invention also relates to a method for operating the illumination apparatus in the dim mode.

  • Publication number: 20130335093
    Abstract: The invention relates to a method for measuring the light properties of light-emitting diodes (LEDs) in an arrangement of a plurality of channels connected in parallel, each having at least one LED per channel and a driver for driving the channels by means of pulse width modulation (PWM), in such a way that at least one pulse of predetermined width can be generated for each channel within a PWM period, wherein the LED of a selected channel is measured during a measurement interval, the measurement interval overlapping a pulse, lying within the PWM period, of a selected channel.

  • Patent number: 8117366
    Abstract: In order to register the order of bus subscribers (12) when starting a system without the use of a token line to be specifically laid for his purpose along the two-wire bus (11), the bus master (13) temporarily activates a reflective discontinuity, preferably a bus short circuit, in a respective selectively addressed one of the subscribers (12) after stochastically determining all subscriber addresses (Ki). The echo signal (19) of a voltage jump (18), which is then output onto the bus (11) by the master (13), is superimposed in the master (13) to form a square-wave-like differential signal (20) whose pulse duration which is proportional to the distance between the master (13) and that subscriber (12) along the bus (11) is measured following pulse shaping by analog pulse area integration (25).
