The invention is an improved device for converting a Twin Lens Reflex (TLR) film camera into Instant Film TLR or Digital Twin Lens Reflex (D-TLR) camera, by using a modular assembly which is the combination of a cartridge holder, an interchangeable instant film cartridge or a minicomputer with a digital sensor (CCD or CMOS) system, and a power bank, all interconnected at the back and bottom of the film camera.

The present disclosure relates to a surgical microscope system and a microscope camera adapter that enable various types of adjustment in a camera adapter connecting the cameras that capture a three-dimensional image, with right and left cameras simultaneously. Of respective right and left lens groups that constitute respective focus lenses, right and left lenses between lenses closest to a side of an objective lens and lenses closest to sides of eye lenses are simultaneously moved by the same distance according to a setting value, by which focus is adjusted. The present invention can be applied to a surgical microscope system.

An apparatus and method are provided. The apparatus includes an imaging device; a stage movable relative to the imaging device; an isolation plate provided between the imaging device and the stage, including a horizontal glass plate; and a plurality of interferometers in electronic communication with a processor. The plurality of interferometers include three interferometers disposed on the imaging device, configured to direct a first beam set in a first direction toward the horizontal glass plate; and three interferometers disposed on the stage, configured to direct a second beam set in a second direction toward the horizontal glass plate, the second direction being opposite to the first direction. The processor is configured to measure distances between the imaging device and the isolation plate and distances between the stage and the isolation plate based on the first beam set and the second beam set reflected from the horizontal glass plate.

One example provides a computing device including a first portion including a first display, a second portion including a second display and a camera, the second portion connected to the first portion via a hinge, a hinge angle sensing mechanism including one or more sensors, a logic device, and a storage device holding instructions executable by the logic device to execute a camera application and to receive sensor data from the one or more sensors, based at least in part on the sensor data received from the one or more sensors, determine a device pose, output the camera application to the first display when the device pose is indicative of the camera being world-facing, and output the camera application to the second display when the device pose is indicative of the camera being user-facing.

Provided is an attachment system for coupling a mobile computing device to an optic device. The optic device may be, but is not limited to a scope, binoculars or the like. The attachment system operates with attachment devices and mounting device with apertures that provide a means to couple a mobile computing device to the optic device in such a way that the attachment system provides a line-of-sight between a camera of the mobile computing device with the lens of the optic device. This allows the camera of the mobile computing device to capture images and video using the high power zoom functionality of the optic device and the convenience of the mobile computing device.

An electronic device includes at least two modules, each module includes at least one component; two adjacent modules of the at least two modules are detachably connected, and the two adjacent modules are electrically connected; the housings of the at least two modules are connected to form the housing of the electronic device; in the at least two modules, the first module includes a mainboard and the second module includes a battery. When any module in the electronic device needs to be updated, the module only needs to be detached from the electronic device, and then the replacement of the module is connected to other modules, thereby forming a new electronic device. There is no need to replace the entire electronic device, and the hardware cost is reduced.
