Abstract: A hybrid combination of analog RF beamforming and digital pre-coding is used to improve signal-to-noise ratio and mitigate interference as between an RF base station and a plurality of wireless receivers within a cell area of the base station. Feedback overhead for beamforming training may be reduced by using indices for identifying the preferred beams of each wireless receiver. Scheduling for channel training may be based on identifying non-colliding ones of the RF beams and assigning these to corresponding wireless receivers which can best use the assigned beams in shared transmission slots.

Abstract: A computing device is provided, including a display configured to display images, a pressure sensor configured to sense at least one of a pressure and a force on the display, and a processor configured to generate a dynamic icon having an image for display on the display, wherein the image is two-dimensional or three-dimensional in appearance, the processor changing an appearance of the image on the dynamic icon upon the pressure sensor sensing at least one of a pressure and a force on the icon.

Abstract: A device for tracing a computer program comprises a non-transitory memory having instructions and one or more processors in communication with the memory. The one or more processors execute the instructions to generate trace code from a trace specification program to trace the computer program. The one or more processors calculate values by executing the computer program and the trace code records, in parallel, the values at a predetermined location in execution of the computer program.
