Publication number: 20210396859Abstract: Systems and methods disclosed herein includes a distance-measuring unit for measuring a distance to an object located in a detection field based on a time-of-flight signal. The distance-measuring unit includes an emitter unit for emitting laser pulses, an optical unit coupling the emitter unit to the detection field, the optical unit configured to guide the laser pulses into the detection field during operation, and a receiver unit having a sensitive sensor surface for receiving laser pulses reflected at the object as echo pulses, wherein the receiver unit is coupled to the detection field by means of the optical unit such that the echo pulses received from the detection field are guided through the optical unit onto the sensor surface during operation.Type: ApplicationFiled: October 23, 2019Publication date: December 23, 2021Applicant: OSRAM GmbHInventors: Thomas Rossmanith, Friedrich Witzani, Alexander Rampitsch

Publication number: 20180156436Abstract: In various embodiments, a leadframe is provided. The leadframe may include connection strips arranged alongside one another, said connection strips being connected via one or a plurality of holding webs. The connection strips have a contact section in each case at their first end section. At least in each case two adjacent connection strips form a strip group. Provision is made of at least one gap region in the region of second end sections of the connection strips of a respective strip group for contacting an electronic component.Type: ApplicationFiled: December 4, 2017Publication date: June 7, 2018Inventors: Thomas Rossmanith, Friedrich Witzani, Alexander Rampitsch

Patent number: 7839093Abstract: Disclosed is a circuit arrangement for supplying a lamp wattage to a high-pressure discharge lamp (Lp) in the form of an alternating current having an operating frequency. The alternating current is generated by a full bridge that is composed of two half-bridge branches. The lamp wattage can be adjusted via the phase which the two half-bridge branches have relative to each other. The lamp wattage is modulated by means of the transmission function of an interface if the operating frequency is frequency-modulated. Said modulation of the lamp wattage can be compensated by adequately correcting the phase.Type: GrantFiled: November 30, 2006Date of Patent: November 23, 2010Assignee: OSRAM Gesellschaft mit beschraenkter HaftungInventors: Herbert Kästle, Thomas Rossmanith
