Assignee: ROKU, INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A remote control system, comprising:
a processing module configured to receive a signal from a user interface and generate, based on the received signal, one or more remote control codes for controlling a device;
a first radiation source configured to generate an electric and magnetic field (EMF) projection based on one or more remote control codes for controlling a device;
a second radiation source configured to generate a visible radiation projection; and
a controller configured to adjust one or more parameters associated with the EMF projection before the EMF projection is emitted to the device and to adjust one or more parameters associated with the visible radiation projection,
wherein the second radiation source is used for calibrating the controller, and
wherein the controller comprises at least one of:
a collimator configured to adjust convergence or divergence of the EMF projection,
a polarizer configured to adjust a polarization of the EMF projection,
an attenuator configured to adjust an energy of the EMF projection, or
a translator configured to change a frequency or a frequency range associated with the EMF projection.
