Abstract:

Techniques and optically excited light-emitting devices based on phosphors are provided to
use phosphor materials which absorb excitation light to emit visible light and
include a composite phosphor material including two or more different
transition metal compounds that, under optical excitation of the excitation
light, emit visible light at spectrally close but different spectral
wavelengths or bands that spectrally overlap to produce a desired color.

Claim 1:

Abstract:

Various embodiments enable one or more appliances to participate in a shared workspace.
The shared workspace can include a single appliance, multiple appliances, a single meeting
room, multiple meeting rooms, or any combination thereof. The state of various
meeting participants can be identified and one or more rules can be applied to
the participants’ state to provide an outcome. An “outcome” can be thought of
as an action that is to be performed responsive to the identified state. An
asset interaction control feature can be selected based on the outcome. The
asset interaction control feature controls, in some manner, a participant’s
interaction with one or more assets that are part of the shared workspace. The
asset interaction control feature is then applied to at least one of the assets.

Claim 1: 

A method comprising:

participating, by an appliance, as part of a shared workspace with one or more other appliances, said participating taking place via one or more networks that enable said appliance and said one or more other appliances to share an asset in different meeting rooms;

identifying individual meeting participants’ state;

causing one or more rules to be applied to the individual meeting participants’ state to provide an outcome, wherein the rules include rules pertaining to asset modification during a collaboration between said appliance and said one or more other appliances to provide an asset-based modification outcome;

selecting an obfuscation level based on the outcome or the asset-based modification outcome, the obfuscation level for at least said outcome to be applied to the shared asset distinctly for at least one of the different meeting rooms sharing the asset; and

causing application of the obfuscation level to the asset in said at least one of the different meeting rooms sharing the asset based on said individual meeting participants’ state.

Abstract

An image is displayed on an electronic display device at a reduced power level.
Power used by the display device is maintained below a predetermined maximum
power level by uniformly scaling the initial optical intensity of an image to a
lower optical intensity whenever displaying the image at the initial optical
intensity would result in power consumption of the display device exceeding the
predetermined maximum power level.

Claim 1:

A method of displaying an image on an electronic display system, comprising:

receiving frames of image data to be displayed, wherein the image data includes an optical output intensity of each pixel and subpixel of a display device of the display system to produce the image or frame and the sub-pixels are red, green, and blue subpixels;

determining an average power level for displaying one or more frames of image data, wherein the average power level is defined as the ratio of the power required by the display device to produce an image at the power required by the display device to produce a fully white screen;

determining an adjusted optical output intensity for each pixel and subpixel as a function of the average power level and the optical output intensity of each subpixel;

adjusting a parameter of the electronic display system in accordance with the average power level, wherein adjusting a parameter comprises scaling the brightness of each pixel and subpixel to the adjusted optical output intensity; and

wherein the electronic display system includes multiple display devices and each display device displays a portion of the image data.
