A head-mounted device may have a display with first and second pixel arrays that display content for a user. A head-mounted support structure in the device supports the pixel arrays on the head of the user. A left positioner may be used to position a left lens module that includes a left lens and the first pixel array. A right positioner may be used to position a right lens module that includes a right lens and the second pixel array. Sensing circuitry such as proximity sensing circuitry may be used to detect relative positions between the left and right lens modules and facing surfaces of a user's nose while the user is wearing the head-mounted support structure. Control circuitry may adjust the positions of the left and right lens modules using interpupillary distance information for the user and using information from the sensing circuitry.

Expansion tool assembly for expandable tubular

Disclosed are an expansion tool assembly, comprising: an expandable tubular; a guide shoe partially inserted into and connected to the lower end of the expandable tubular; a sealing sleeve arranged in the expandable tubular and connected to the upper end of the guide shoe; an expansion assembly comprising an expansion cone and expansion seat disposed inside the expandable tubular, wherein the lower end of the expansion seat is connected with hooks, which can be rested on the upper end of the sealing sleeve; an upper joint that is connected to the upper end of the expansion seat and can be connected to a drill string. A force transfer path can be established via connection between the expansion seat and sealing sleeve, so that expandable tubular weight is borne on the drill string. Unintentional expansion of the expandable tubular, caused by interaction between expandable tubular and expansion cone, can be avoided.

Shared Compressor

A system includes a compressor that receives air from a source and is configured to supply compressed air, a first system that is configured to receive the compressed air, and a second system that is configured to receive the compressed air. In first control mode, a first control valve blocks flow of compressed air to the first system and a second control valve allows flow of compressed air from to the second system. In a second control mode, the second control valve allows flow of the compressed air from the second system to a dryer along, and the first control valve allows flow of the compressed air from the dryer to the first system.

Inclined shaft construction method, and inclined shaft construction system

Inclined shaft construction method and an inclined shaft construction system. When a pilot tunnel is excavated, a plurality of sleeves are sequentially connected to a rear side of a pilot tunnel boring apparatus along with forward excavation by the pilot tunnel boring apparatus, the pilot tunnel boring apparatus is removed after pilot tunnel boring is completed, an expansion-excavation boring apparatus is mounted, the expansion-excavation boring apparatus is directly or indirectly connected to a frontmost sleeve, the expansion-excavation boring apparatus is pulled to perform reverse expansion-excavation by means of a push-pull oil cylinder, and each time expansion-excavation is performed by a distance of one sleeve in an expansion-excavation process, a rearmost sleeve is removed until the pilot tunnel is expanded-excavated and formed.

On-demand release tool system and methodology

A technique facilitates on-demand release of desired sections of a well string, e.g. sections of a perforating gun string, via at least one on-demand release tool. The on-demand release tool has an activation mechanism which may be selectively actuated to transition the on-demand release tool from a first loadbearing configuration to a second loadbearing configuration. The on-demand release tool may then be transitioned to a release stage which allows a first section of the on-demand release tool to be separated from a second section of the on-demand release tool by activating a release mechanism. In at least some applications, the on-demand release tool also comprises a ballistic transfer device to enable reliable ballistic transfer between sections of the perforating gun string.

Changing keyboard layout automatically while entering a password

A system and method for automatically reconfiguring a keyboard layout display to facilitate entry of password characters. The system analyzes the password while setting it, and will save a required keyboard layout for each character. A method includes obtaining an encoded sequence of keyboard layouts mapped to a corresponding characters sequence of a user password, receiving input of a password character and determining whether the character input is correct. If the character entered is correct: decoding the keyboard layout sequence to obtain a correct keyboard layout associated with a next password character to be entered; and automatically displaying the correct keyboard layout associated with a next character to be entered; or if the character entered is not correct: decoding the keyboard layout sequence to obtain one of: a correct or incorrect keyboard layout associated with a next password character to be entered; and automatically displaying the correct or incorrect keyboard layout on the device.

可自動調配之一氧化氮觸媒系統

Method and system for automated shaped cooling hole measurement

An automated measurement system includes multi-axis imager configured to receive images of a workpiece wherein the images include visual information about the workpiece at a plurality of focus planes or visual information about the workpiece between at least two focus planes. The multi-axis imager is also configured to determine a point cloud of a plurality of 3 D data points wherein each of the plurality of 3 D data points represents an intersection of one of the plurality of focus planes with a surface of the workpiece or positional information of the workpiece in a de-focused area between the at least two focus planes. The multi-axis imager is further configured to determine a plurality of dimensions of features of the workpiece and compare the determined plurality of dimensions of the features to manufacturing specifications corresponding to at least some of the determined plurality of dimensions of the features.

Head-mounted electronic device

A head-mounted device may have a head-mounted housing. The housing may include a chassis with left and right openings that overlap respective left and right optical modules that present images eye boxes. Each optical module may have a lens and display that presents an image through the lens. The chassis may have an inner frame and outer frame. A middle portion of the chassis may form a stiffened nose bridge structure. Components in the housing such as a display, a fan housing, a heat sink layer, optical module guide rods, and a rear cover may span the width of the housing and may be attached to edge portions of the chassis, thereby forming a box-shaped structure that provides rigidity and helps prevent housing deformation.
