Abstract: Provided is a two-stage reverse-torque bent screw orientation tool. An existing bent screw orientation technology has the technical problems of large friction resistance, difficult control of a borehole track, a low drilling speed and the like, and restricts economic, safe and long-acting development of oil and gas. In order to solve the above problems, the two-stage reverse-torque bent screw orientation tool is invented and composed of a first-stage clutch mechanism and a second-stage clutch mechanism, and the first-stage clutch mechanism and the second-stage clutch mechanism are both composed of a battery, a battery compartment, a pressure sensor, an electromagnetic valve, a body, a plug, a piston, an outer tooth cylinder, an inner tooth cylinder, a transmission cylinder, a connecting cylinder, a bearing, a limiting cylinder, a lower joint, a thrust bearing, a battery compartment, a circuit board, a cover plate and the like.

Abstract: An electronic device such as a head-mounted device may have a display that displays computer-generated content for a user. The head-mounted device may have an optical system that directs the computer-generated content towards eye boxes for viewing by a user. The optical system may include a spatially addressable adjustable optical component. The adjustable optical component may have first and second electrodes and an electrically adjustable material between the first and second electrodes. The electrically adjustable material may include a transparent conductive material such as indium tin oxide that includes a pattern of segmented trenches configured to provide the transparent conductive material with electrical anisotropy. Contacts may be coupled to the transparent conductive material. Control circuitry can adjust the electrically adjustable material to form a spatially addressable light modulator or adjustable lens.

Abstract: An electronic device may have a housing. Input-output devices may be mounted in the housing. The input-output devices may include a display with an array of pixels configured to display images for a user. The electronic device may have an optical component formed under a transparent region in the housing. The transparent region may be associated with an opening in an opaque masking layer in an inactive area of the display or other portion of the electronic device. A diffuser may be formed between the optical component and the transparent region. The diffuser may have a polymer layer with embedded thin-film interference filter flakes configured to scatter light and to exhibit desired reflection and transmission spectral.

Abstract: An electronic device includes an input device. The input device has an input/output module below or within a cover defining an input surface. The input/output module detects touch and/or force inputs on the input surface, and provides haptic feedback to the cover.

Abstract: An electronic device may have transparent housing structures such as walls formed of glass or sapphire. Housing structures such as transparent housing structures may have a colored coating. The colored coating may include an absorptive layer and a metal layer. The coating may exhibit a color that can be adjusted by adjusting the thickness of the thin absorptive layer. A colored layer such as a layer of colored polymer may be incorporated into the colored coating to further adjust the color of the coating. The colored coating may be formed on an inner or outer housing structure surface. The surface may have a texture to provide the coating with a matte appearance. When formed on an outer surface, a diamond-like carbon layer may protect the colored coating. When formed on an inner surface, a passivation layer may be used to prevent oxidation of the metal layer.

Abstract: An electronic device includes a housing and a display. The housing defines an interior cavity and includes an optically-transmissive housing component. The display is disposed in the interior cavity and is viewable through the optically-transmissive housing component. An optoelectronic component is disposed in the interior cavity. An optical fiber extends between a first end positioned adjacent the optoelectronic component and a second end positioned adjacent the optically-transmissive housing component. The optical fiber defines a non-linear optical path between the first end and the second end. At least a portion of the optical fiber is laterally offset from a lateral edge of the display.

Abstract: A transparent high-conductivity layer for providing electrostatic feedback to a user of an electronic device. The transparent high-conductivity layer is positioned over a capacitive input sensor and has a resistivity sufficiently high to prevent interference with the capacitive input sensor. As one example, the transparent high-conductivity layer can be formed from a layer of geometrically-separated regions of high-conductivity material. The average distance between geometrically-separated regions can substantially define the resistivity of the transparent high-conductivity layer.

Abstract: An electronic device may have a housing with a display. A transparent portion of the housing may serve as a display cover layer and may overlap an array of pixels in the display. The array of pixels may form an active area of the display for displaying images for a user. An ambient light sensor window may be formed in an inactive area of the display that does not overlap pixels. An ambient light sensor may be mounted in an interior region of the housing. A metal-coated light guide may have a first end aligned with the ambient light sensor window to receive ambient light from an exterior region surrounding the device and may have a second end at which the ambient light is provided to the ambient light sensor.

Abstract: An electronic device may be provided with a color ambient light sensor. The color ambient light sensor may be used to measure an ambient light spectrum over a wavelength range of interest. Control circuitry in the electronic device can take actions based on the measured ambient light spectrum such as adjusting the brightness and color cast of content on a display. A display may have a display cover layer. The color ambient light sensor can be mounted under the display cover layer and may receive ambient light through the display cover layer. The color ambient light sensor may have a tunable wavelength filter such as an electrically adjustable Fabry-Perot resonator. A light collimator may be interposed between the display cover layer and the Fabry-Perot resonator to collimate ambient light that is passed to the Fabry-Perot resonator. A light detector measures the light passing through the Fabry-Perot resonator.
