Description

REMOTE COMMUNICATION WITH ENERGIZED DEVICES USING A COHERENT VISIBLE LIGHT BEAM
PRIORITY CLAIM [0001] The present document claims priority to U.S. Patent Application 62/586,831, entitled “CHROMATIC KEYED SYSTEM CONTROL./' filed on November 15. 2017, which is incorporated herein by reference in its entirety.
TECHNICAL FIELD [0002| The disclosed subject matter relates to the field of electronics, and in particular, a system and method for remotely communicating information to electronic devices.
BACKGROUND
Many remote devices interact with external devices through radio frequency, infrared, or other wireless communication. These communication methods require configuration of the remote devices to connect with external devices. This configuration causes setbacks in accessibility and setup of remote devices with external devices.
Accessibility means that the remote device may be easily replaced and may be used on different external devices. However, replacing remote devices requires a particular remote device to communicate with the external device. Additionally, remote devices are usually incompatible with other external devices. Setup means the time and steps required to initiate communication between the remote and external devices. However, the setup of many remote devices often requires a series of time-consuming and technical steps. Furthermore, a setup failure results in the inability to communicate with external devices.
|0003| Thus, a reliable remote device that is easily accessible and configurable on a variety of devices is necessary.

DETAILED DESCRIPTION [0088] In the following detailed description, reference is made to the accompanying drawings that form specific embodiments by way of illustration in which the disclosed subject matter can be practiced. However, it should be understood that other embodiments may be utilized, and structural changes may be made without departing from the scope of the disclosed subject matter. /Any combination of the following features and elements is contemplated to implement and practice the disclosure.
[0089] Brief Introduction [0090] The following disclosure was created and inspired in response to adjusting several different clocks following changes in daylight savings. The inventor’s father owned many different clocks requiring manual adjustment that were inaccessible without the use of special equipment. Inventor envisioned systems utilizing remote communication could be much more
1002368410
2018264086 15 Nov 2018 accessible and easier to control with an interface responding io common handheld laser pointers, including his father’s clocks.
|0091| Presently, remote control devices dial control operation of consumer electronics such as televisions and DVD players, typically use a frequency range that is neither visible not. audible to users and thus provides user feedback only upon producing a desired effect in the device being controlled. Furthermore, the radio frequency signal emitted by the remote control tends to be non-coherent and spreads over a wide angle, often causing annoyances such as inadvertently changing channels on ail set-top boxes within the range of the remote control. Furthermore, remote controls themselves have become bulky and complex and therefore have become expensive and custom in their use. The techniques disclosed in the present document may be incorporated in embodiments that allow for transmission or reception of control signals in the visible light spectrum, providing a low complexity and intuitive tool to uses to remotely or wirelessly control devices that are hard to reach. At the same time, due to the use of visible light, such devices are robust from spoofing or hacking that may occur in radio frequency controlled devise, because the light carrying control signal will be limited to a physical proximity of the device being controlled.
[00921 A method and system for remotely communicating with electric devices with a visible light beam are disclosed. A remote device emits a visible light beam received by a sensor at a distance. Visual feedback is provided when the visible light beam is received by the sensor. The sensor detects at least one characteristic of the visible light beam or of the photoluminesuent radiation from a fluorescent medium. The characteristic mav be a chromatic wavelength or a modulated signal. The chromatic wavelength or modulated signal is associated with a signal readable by the electric device. When the sensor matches the detected characteristic to a table entry, the signal is generated and sent to the electric device.
