摘要： System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.

摘要： Improved techniques for generating images are disclosed herein. A first image is generated by an integrated camera. The pose of the computer system is determined based on the image, and a timestamp is determined. A detached camera generates a second image. The second image is aligned with the first image. An overlaid image is generated by overlaying the second image onto the first image based on the alignment. A pose difference is then identified between a current pose of the computer and the initial pose. Consequently, late stage reprojection (LSR) is performed on the overlaid image to account for the pose difference. The LSR-corrected overlaid image is then displayed.

摘要： A method includes receiving, through a network by a computing system associated with an artificial-reality device, video data of a user of a second computing system comprising a first and second image of the user. The first and second images may be captured concurrently by a first camera and a second camera of the second computing system, respectively. The computing system generates a planar proxy for displaying the user and determines a pose for the planar proxy within a three-dimensional virtual environment. The computing system renders a left image for a left-eye display and a right image for a right-eye display of the artificial-reality device based on the planar proxy having the determined pose and the first image, and the planar proxy having the determined pose and the second image, respectively. The computing system displays the rendered left image and right image using the left-eye display and right-eye display, respectively.

摘要： The present invention relates to a system and method for capturing video of a real-world scene over a field of view that may exceed the field of view of a user, manipulating the captured video, and then stereoscopically displaying the manipulated image to the user in a head mounted display to create a virtual environment having length, width, and depth in the image. By capturing and manipulating video for a field of view that exceeds the field of view of the user, the system and method can quickly respond to movement by the user to update the display allowing the user to look and pan around, i.e., navigate, inside the three-dimensional virtual environment.

摘要： Eyewear that is configured to be wirelessly charged and also wirelessly communicate with a case charger having a battery using time gating power transfer. In one example, wireless charging and bidirectional communication of the eyewear can be performed using a unidirectional communication protocol, such as the Qi baseline power profile (BPP) which is only suited for unidirectional communication. The eyewear has a processor configured to send data to the wireless power charger that instructs the wireless power charger to stop wireless charging for a time period that is correlated to a state of charge (SOC) of the wireless power charger battery. The wireless power charger resumes charging of the eyewear battery after the time period, and the eyewear determines the SOC of the wireless power charger battery to be a percentage that correlates to the time period.

摘要： A stereoscopic imaging apparatus for use in a robotic surgery system is disclosed and includes an elongate sheath having a bore. First and second image sensors are adjacently mounted at the distal end to capture high definition images from different perspective viewpoints for generating three-dimensional image information. The image sensors produce an unprocessed digital data signal representing the captured images. A wired signal line transmits the unprocessed digital data signals along the sheath to a proximal end to processing circuitry. The processing circuitry is configured to perform processing operations on the unprocessed digital data signals to produce respective video signals suitable for transmission to a host system or for driving a 3D display. A secondary camera is also disclosed and includes an elongate strip of circuit substrate sized for insertion through a narrow conduit, the strip of circuit substrate connecting between an image sensor and a processing circuit substrate.

摘要： A system and method for generating a depth map from image data in a surgical robotic system that employs a robotic subsystem having a camera assembly with first and second cameras for generating image data. The system and method generates based on the image data a plurality of depth maps, and then converts the plurality of depth maps into a single combined depth map having distance data associated therewith. The system and method can then control the camera assembly based on the distance data in the single combined depth map.
