This application describes covers for electronic devices, electronic devices, and methods for making the covers. In one example, described herein is a cover for an electronic device comprising: a substrate comprising a metal; a passivation layer or a micro-arc oxidation layer deposited on at least one surface of the substrate; a primer coating layer on the passivation layer or the micro-arc oxidation layer; an optional base coating layer on the primer coating layer; a top coating layer on the optional base coating layer or on the primer coating layer; and a hydrophobic coating layer.

An electronic device may have a glass housing structures. The glass housing structures may be used to cover a display and other internal electronic device components. The glass housing structure may have multiple glass pieces that are joined using a glass fusing process. A peripheral glass member may be fused along the edge of a planar glass member to enhance the thickness of the edge. A rounded edge feature may be formed by machining the thickened edge. Raised fused glass features may surround openings in the planar glass member. Multiple planar glass members may be fused together to form a five-sided box in which electronic components may be mounted. Raised support structure ribs may be formed by fusing glass structures to a planar glass member. Opaque masking material and colored glass may be used to create portions of the glass housing structures that hide internal device components from view.

A mobile terminal is provided with a housing, a circuit board included in the housing and having a thickness direction normal to a plane of the circuit board, a battery pack included in the housing, and a non-contact charging module included in the housing. The non-contact charging module includes a charging coil formed of a wound conducting wire; a communication coil arranged adjacent to the charging coil; and a magnetic sheet on which the charging coil and the communication coil are arranged. The magnetic sheet has four edges that collectively define a rectangular profile of the magnetic sheet, and at most three pairs of adjacent edges respectively meet to form at most three corners. At least a portion of the non-contact charging module overlaps with the circuit board as viewed in the thickness direction of the circuit board.

According to various embodiments of the disclosure, an electronic device may include: a first housing, a second housing rotatably coupled with the first housing and configured to rotate between a first position at which the second housing at least partially faces the first housing and a second position at which the second housing is unfolded at a specified angle from the first position, a hinge module including a hinge providing at least one folding axis and rotatably coupling the first housing and the second housing about the folding axis, and a hinge cover disposed between the first housing and the second housing and coupled to surround at least a part of the hinge module, and at least one part of the hinge cover may be configured to be located closer to the hinge module at the second position than at the first position.

To appropriately capture an image that cannot be directly viewed. A program that causes a processor to execute: detection of a first target in a first image acquired by a first camera; estimation of a length of a path from the detected first camera to the first target; and switching of display of a second image acquired by a second camera on the basis of the length of the path, and synthesis of an index for adjusting a position of a second target in the second image.

Systems and methods for eliminating or mitigating T-effects on Hall sensors. A system may comprise a magnet-coil arrangement for providing a relative movement therebetween to obtain a relative position, a Hall sensor for sensing the relative movement, a temperature sensor located in proximity of the Hall sensor for providing temperature sensing, and a controller having two or more channels coupled to Hall sensor and to the temperature sensor and configured to control the relative movement and to provide, based on the temperature sensing, a temperature correction input to the Hall sensor for compensating a temperature effect on the Hall sensor sensing.

Apparatuses, systems, and methods are provided for ultrasonic fingerprint sensors that are able to be used to detect fingerprints from opposing sides of an apparatus, e.g., a smartphone with screens on both sides of the housing. Some implementations of such sensors may include, for example, two piezoelectric and sensor pixel layer assemblies coupled to a common controller. Other implementations of such sensors may include, for example, a single piezoelectric and sensor pixel assembly coupled with a controller configured to apply a range-gate delay to obtain fingerprint scans from either opposing side of an apparatus. Yet further implementations of such sensors may include acoustic masking layers to spatially filter ultrasonic waves propagating to either side of an apparatus.

Modular lens adapter system are provided for use with a hand held computer device having a camera for mobile ophthalmoscopy. The modular lens adapter systems include an anterior adapter and a posterior adapter configured to removably engage with a hand held computer device. The anterior adapter can include a variable intensity light source, a clamp, and a movable macro lens. The posterior adapter can include a hand held computer device mount, a lens mount, and a telescoping arm with a first end and a second end with the first end configured to removably engage with the mount and the second end configured to contact the lens mount.
