Systems and methods for event-detection confirmation are disclosed. For example, a sensing device may generate sensor data, such as from radar, and the sensor data may be utilized to determine if a predefined event as occurred. Event-confirmation operations may then be performed, such as by utilizing acoustic-event detection techniques and/or natural language understanding techniques. When occurrence of an event is confirmed, such as to a certain confidence level, one or more actions may be taken, such as sending a notification to another device and/or establishing a communication channel with another device, such as a device associated with emergency services, family members, friends, and/or neighbors.

Event-detection confirmation by voice user interface

Systems and methods are disclosed for augmented reality devices with prescription lenses. An example augmented reality device may include a frame and a lens coupled to the frame. The lens may include a prescription lens configured to refract light, the prescription lens having a first index of refraction value, a waveguide encapsulated in the prescription lens, the waveguide having a second index of refraction value, and a first coating layer disposed on a first side of the waveguide, the first coating layer having a third index of refraction value. The third index of refraction value may be less than the first index of refraction value, and the first index of refraction value may be less than the second index of refraction value.

A bistable electro-optic display has a plurality of pixels, each of which is capable of displaying at least three gray levels. The display is driven by a method comprising: storing a look-up table containing data representing the impulses necessary to convert an initial gray level to a final gray level; storing data representing at least an initial state of each pixel of the display; receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary to convert the initial state of said one pixel to the desired final state thereof, as determined from said look-up table. The invention also provides a method for reducing the remnant voltage of an electro-optic display.

Electro-optic displays

In some implementations, an electronic device includes a display stack to display content. The display stack can include a number of substrates coupled using a first optically clear adhesive (OCA) and a second OCA. In an implementation, the first OCA includes an acrylic-containing OCA and the second OCA includes a silicon-containing OCA. In some instances, the first OCA can include an additive to filter ultraviolet radiation. In a particular implementation, the first OCA can have a total luminous transmittance of no greater than approximately 30% for at least a portion of the UV spectrum radiation.

An electrowetting display device comprises electrowetting pixels. Each of the electrowetting pixels includes a hydrophobic layer portion disposed on a first electrode, an electrolyte solution overlying the hydrophobic layer, and a thin film transistor (TFT) that is switched on to select each of the electrowetting pixels using active matrix addressing, wherein the TFT is in electrical contact with the first electrode. The electrowetting display further includes a second electrode in electrical contact with the electrowetting pixels, and a reset control circuit in electrical contact with the second electrode to provide a reset pulse in unison to the electrowetting pixels.

Global reset for an electrowetting display device

A method for addressing a bistable electro-optic display having at least one pixel comprises applying an addressing pulse to drive the pixel to a first optical state; leaving the pixel undriven for a period of time, thereby permitting the pixel to assume a second optical state different from the first optical state; and applying to the pixel a refresh pulse which substantially restores the pixel to the first optical state, the refresh pulse being short relative to the addressing pulse.

An electrowetting display device includes a plurality of pixels and a packaged integrated circuit that includes an output pin configured to electrically connect to a display driver, a rendering engine configured to output an initial luminance value for a first pixel in a plurality of pixels, and a memory controller. The memory controller includes a first frame buffer storing a current luminance value for the first pixel, a second frame buffer, and a front-end interface controller configured to encode a next luminance value. The next luminance value is at least partially determined by the initial luminance value for the first pixel. The memory controller includes a back-end interface controller configured to transmit a data signal through the output pin to the display driver to cause the display driver to apply a driving voltage to the first pixel. The driving voltage is at least partially determined by the current luminance value.

A display device includes a first support plate and an opposing second support plate. A plurality of pixel regions is formed between the first support plate and the second support plate. Each pixel region includes a plurality of sub-pixel regions. A plurality of pixel wall portions over the first support plate form a perimeter of each of the plurality of sub-pixel regions. A sub-pixel region spacer is positioned in a first sub-pixel region of the plurality of sub-pixel regions. The sub-pixel region spacer includes a first spacer portion in the first sub-pixel region having a first landing surface extending between the plurality of pixel wall portions forming the perimeter of the first sub-pixel region.

Devices such as electronic book readers, televisions, and so forth may use reflective display technologies. Described herein are devices and methods for ambient light sensing for use in conjunction with displays. A light guide panel is coupled to a light sensor to measure ambient light impinging on the light guide panel. Where the display is reflective, the light guide panel may be configured to provide for illumination of the display.

An electro-optic display, having at least one pixel capable of achieving any one of at least four different gray levels including two extreme optical states, is driven by displaying a first image on the display, and rewriting the display to display a second image thereon, wherein, during the rewriting of the display, any pixel which has undergone a number of transitions exceeding a predetermined value without touching an extreme optical state, is driven to at least one extreme optical state before driving that pixel to its final optical state in the second image.
