2. A method, comprising:
receiving, by an endpoint from a client, an image generated by the client;
determining, by the endpoint, that the image generated by the client includes a matrix barcode;
decoding, by the endpoint, the matrix barcode to determine one or more instructions associated with text encoded within the matrix barcode; and
performing the one or more instructions associated with the encoded text;
receiving a video stream from the client, the video stream including the image generated by the client; and
wherein the video stream is received over a Video Graphics Array (VGA), Digital Visual Interface (DVI), or High-Definition Multimedia Interface (HDMI) video cable coupled between the endpoint and the client.
3. The method of claim 2, wherein the video stream is received from the client while the video stream is displayed by the client.
4. The method of claim 2, wherein determining that the image generated by the client includes a matrix barcode comprises determining that the image includes a Quick Response (QR) code.
5. The method of claim 2, wherein the text encoded within the matrix barcode is one or more user credentials of a user associated with the client.
6. The method of claim 5, wherein the performing the one or more instructions associated with the encoded text includes:
verifying the user credentials with a login server connected to the endpoint through a network; and
providing the client with access to one or more functions of the endpoint in response to the verification of the user credentials.
7. The method of claim 5, wherein the performing the one or more instructions associated with the encoded text includes customizing the endpoint according to one or more customization parameters associated with the login information.
8. The method of claim 2, further comprising:
displaying a prompt querying whether the one or more instructions should be performed; and
wherein the one or more instructions are performed after receiving a positive response to the displayed prompt.
9. The method of claim 2, wherein the image is a first image and the method further comprises:
capturing a second image generated by the client;
determining that the second image generated by the client does not include a matrix barcode; and
capturing the first image upon waiting a predetermined period of time after the second image is captured or after the determination that the second image generated by the client does not include a matrix barcode.
10. The method of claim 2, wherein the performing the one or more instructions associated with the encoded text includes establishing a communication session with one or more users that are distinct from a user of the client.
11. The method of claim 2, wherein the endpoint is a computing system that includes a processor capable of facilitating a videoconference session with another endpoint.
12. One or more computer readable tangible media comprising logic that when executed is operable to:
receive, from a client, an image generated by the client;
determine that the image generated by the client includes a matrix barcode;
decode the matrix barcode to determine one or more instructions associated with text encoded within the matrix barcode; and
perform the one or more instructions associated with the encoded text;
wherein the image is received in a video stream from the client; and
wherein the video stream is received over a Video Graphics Array (VGA), Digital Visual Interface (DVI), or High-Definition Multimedia Interface (HDMI) video cable coupled between the endpoint and the client.
13. The media of claim 12, wherein determining that the image generated by the client includes a matrix barcode comprises determining that the image includes a Quick Response (QR) code.
14. The media of claim 12, wherein the text encoded within the matrix barcode is one or more user credentials of a user associated with the client.
15. The media of claim 12, wherein the logic is further configured to receive the image by capturing a photo or video of a display of the client.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A light fixture (2), comprising:
a metallic frame (14) including a central planar section (40) and first and second wings (42) extending angularly downward from said center section;
a first plurality of light emitting diodes (12) mounted and thermally coupled to said central planar section of said frame (14);
first and second reflectors (20) mounted to said frame so as to substantially cover downward-facing sides of said first and second wings, respectively; and
a sealed housing enclosing said frame, said first and second reflectors, and said first plurality of light emitting diodes; whereby
said frame draws heat away from said plurality of light emitting diodes; and
said first and second reflectors focus and concentrate light emitted by said first plurality of light emitting diodes and reflect heat radiated by said first and second wings.
2. The light fixture of claim 1 further comprising:
a first gap (53) disposed between said first reflector and said first wing; and
a second gap (53) disposed between said second reflector and said second wing; whereby said first and second gaps act as insulators.
3. The light fixture of claim 1 further comprising:
a printed circuit board (28) carrying said plurality of light emitting diodes;
a thermally conductive interface (65) disposed between and in contact with said printed circuit board and said frame, said interface being operative to wet a first surface area of said frame and a second surface area of said printed circuit board so as to maximize heat transfer from said printed circuit board to said frame.
4. The light fixture of claim 1 further comprising:
an electrical enclosure (52) disposed within said sealed housing.
5. The light fixture of claim 4 wherein:
said electrical enclosure is formed in part by at least a portion of said frame.
6. The light fixture of claim 4 further comprising:
a power supply circuit (18) disposed within said electrical enclosure.
7. The light fixture of claim 4 further comprising:
a battery (24) disposed within said electrical enclosure.
8. The light fixture of claim 1 further comprising:
a second plurality of light emitting diodes (22);
