  • Electromagnetic Trap Multiplexing
    Publication number: 20250052659
    Abstract: Time multiplexing an electromagnetic trap beam may be used to generate trap shapes/geometries to trap one or more particles with one electromagnetic beam by directing the electromagnetic beam at a pattern of different locations with sufficient rapidity to form an effective shape/geometry. Additionally, multiplexing an electromagnetic trap beam may be used to shutter trapping electromagnetic radiation to protect a viewer, use the same beam for multiple functions, move and organize particles, and generate illumination effects.
    Type: Application

  • Method and apparatus for modifying an encoded signal
    Publication number: 20060217972
    Abstract: Signal Quality Enhancement is performed directly in a coded domain. Coded Domain-Signal Quality Enhancement (CD-SQE) is applied to an encoded signal populated substantially with encoded signal bits to produce an enhanced encoded signal. The enhanced encoded signal is outputted. Thus, the signal does not have to go through intermediate decoder/re-encoder(s), which can degrade overall speech quality. Computational resources required for a complete re-encoding are not needed. Overall delay of the system is minimized. The CD-SQE system can be used in any network in which signals are communicated in a coded domain, such as a Third Generation (3G) wireless network.
