  • Publication number: 20240066401
    Abstract: Methods and systems for providing a dynamic asynchronous choice system (DAX) for a plurality of different user computing devices are described herein. A first series of prompts may be generated and provided to a first user computing device as part of a first scene in a multiplayer interactive application. Based on a first set of responses received in response to that first series of prompts, a second series of prompts may be generated, the first scene might be modified, and the modified first scene might be provided to a second user computing device along with the second series of prompts. A second set of responses may be received in response to that second series of prompts. Based on the first set of responses and the second set of responses, a second scene may be selected and provided to the first user computing device and the second user computing device.

  • Publication number: 20150326419
    Abstract: A radio communication system includes a frequency synthesizer, a radio frequency (RF) front end, a first receiver, and a second receiver. The frequency synthesizer is configured to generate an oscillation signal, and the RF front end is configured to receive a detected RF signal and apply the oscillation signal to downconvert the RF signal to an intermediate frequency (IF) signal. More particularly, the first receiver, coupled to the RF front end, is configured to extract, from the IF signal, information wirelessly transmitted by a first RF transmitter on a first frequency channel. The second receiver, coupled to the RF front end, is configured to extract, from the IF signal concurrently with the extraction of signal information by the first receiver, information wirelessly transmitted by a second RF transmitter on a second frequency channel.

  • Patent number: 8583059
    Abstract: Described is a method for operating a power semiconductor component. A power amplifier provided with a programmable logic is assigned to this power semiconductor component. In at least one embodiment, control signals for the power semiconductor component are transmitted to the power amplifier. The power semiconductor component is influenced by the power amplifier in dependence on these control signals. The type and manner in which the power semiconductor component is influenced is determined by the programming of the logic. The power amplifier can be sent programming signals which are then processed by a processor of the power amplifier. The programming of the logic is changed by the processor in dependence on the programming signals.

  • Patent number: 8410422
    Abstract: The invention is related to the adjustment of characteristics of a beam bundle of high-energy radiation emitted from a plasma, particularly for applications in semiconductor lithography. For acquiring and adjusting characteristics of a beam bundle of high-energy radiation emitted from a plasma and focused by means of collector optics, an intensity distribution of the radiation is acquired over the cross section of a convergent beam bundle in a measuring plane perpendicular to the optical axis in front of an intermediate focus of the collector optics, and intensity values are recorded in defined sectors for a quantity of reception regions of a measuring device which are aligned with different radii concentric to the optical axis, and measured quantities and control variables are determined from a comparison of the intensity values of different sectors for aligning the collector optics.
