Abstract:
An image capturing device including a mode switch rotatable to change a pointing position movable between three predetermined positions corresponding to at least three image-capturing modes including a first mode, a second mode, and a third mode, to switch between the first mode, the second mode, and the third mode. The image capturing device further includes a power switch and circuitry. The power switch receives a user input for turning on or off the power of the image capturing devices. The circuitry controls the image capturing device to operate in one of the three image-capturing modes. When the power switch receives a user input for turning on the power, the circuitry controls the image capturing device to operate in one of the three image-capturing modes corresponding to the pointing position of the mode switch that has been set when the power switch is turned off.
Abstract:
A non-reciprocal device incorporating metamaterials which exhibit non-reciprocity through angular momentum biasing. The metamaterial, such as a ring resonator, is angular-momentum biased. This is achieved by applying a suitable mechanical or spatio-temporal modulation to resonant inclusions of the metamaterial, thereby producing strong non-reciprocity. In this manner, non-reciprocity can be produced without requiring the use of large and bulky magnets to produce a static magnetic field. The metamaterials of the present invention can be realized by semiconducting and/or metallic materials which are widely used in integrated circuit technology, and therefore, contrary to magneto-optical materials, can be easily integrated into the non-reciprocal devices and large microwave or optical systems. The metamaterials of the present invention can be compact at various frequencies due to the enhanced wave-matter interaction in the constituent resonant inclusions. Additionally, by using the metamaterials of the present invention, the power consumed in the biasing network is drastically reduced.

Abstract:
Techniques for rendering images directly with light conversion materials are described. In some embodiments, image data for one or more image frames is received. A light source may be controlled to emit first light to irradiate a light conversion material disposed with an image rendering surface. Second light that renders the one or more image frames may be emitted from the light conversion material. The second light emitted from the light conversion material may be excited by the first light. A display system under techniques herein may be free of a light valve layer on which light transmittance is modulated on a pixel-by-pixel basis.
