Embodiments are directed to a support apparatus. The support apparatus might comprise a body configured to support an entity. The body might comprise a material that has a physical property. The support apparatus might further comprise a coupler system configured to couple electric current from a power source to the material. The material is arranged such that coupling an electric current to the material changes the physical property of the material. Embodiments are further directed to a method. The method might comprise forming one or more cavities in a support apparatus. The method might further comprise providing one or more couplers in electrical contact with each of the one or more channels. The method further comprises filling each of the one or more cavities with a fluid that has electrically changeable rigidity. Finally, the method might comprise connecting a power source to each of the one or more couplers.

A power tool including an electric motor is provided. The tool includes a substantially disc-shaped printed circuit board (PCB), power switches mounted on the PCB; magnetic sensors mounted on the PCB facing the motor; a heat sink in thermal communication with the power switches disposed between the PCB and the electric motor; and a molded casing structurally securing the heat sink relative to the PCB. The molded casing includes a center opening, at least one first opening provided at a first radial distance from the center opening arranged to receive the magnetic sensors therein, and at least one second opening provided at a second radial distance from the center opening arranged to securely receive the heat sink therein.

Disclosed are a supporting structure having a variable form and an electronic device having the same. A supporting structure may include a fixing module, a tail end module, and a flexible module connecting the fixing module and the tail end module. The flexible module may include multiple chain units. The chain unit may include a support plate having a support surface and a lower surface opposite to the support surface, and a driving portion extending along from a side of the support plate away from toward the lower surface of the support plate. The chain units are hingedly connected in series. Adjacent chain units may drive the support surfaces to construct different forms through interaction between the driving portions, thereby forming the supporting structure whose form can be flexibly changed.

An electronic device usable in a manner similar to reading a book and a novel electronic device are provided. The electronic device includes flexible first to n-th display panels (n is a natural number of 4 or more) and an shaft. The first to n-th display panels each include a first surface and a second surface opposite to the first surface. The first and second surfaces are provided with the first and second display portions, respectively. The shaft includes an operating circuit, to which the first to n-th display panels are electrically connected. The first display panel and the second display panel nearest to the first display panel are fixed to the shaft so that an angle formed by straight lines connecting a portion where the first display panel projects from the shaft and the center of the shaft and connecting a portion where the second display panel projects from the shaft and the center of the shaft is (360/n)° in a cross-sectional view along a plane orthogonal to an extending direction of the shaft.

A handheld mount assembly for portable electronic device includes a pistol style grip and suction cup assembly. The mount assembly functions as a gripping device for handheld use, a hands free stand, and a recharging station. The mount can be secured anywhere on the back of the electronic device, making the angle adjustable for stand use, and also allowing the user to position the device differently to accommodate his/her own needs. The mount can power/charge the portable wireless device as well as wirelessly connect to it and integrate its operational controls to those three tactile controls of the mount assembly.

A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.

A charging apparatus for a handheld electronic device includes a housing configured to removably attach to the handheld electronic device. The housing includes at least one electronic logic board, and an accessory station configured to store and charge at least one accessory item of the handheld electronic device. The electronic logic board includes a coil configured to wirelessly provide or accept power to and from the handheld electronic device. A software installed on the electronic logic board is configured to control a power transfer between at least two of the following: the accessory item, the accessory station, the housing, and the handheld electronic device. The housing includes a magnetic material configured to removably attach to a corresponding magnetic material of the handheld electronic device.

Examples are disclosed herein that relate to curved batteries. One example provides a battery comprising an anode arranged on an anode substrate, a cathode arranged on a cathode substrate, the anode substrate being curved at a first curvature and the cathode substrate being curved at a second curvature, and a separator between the anode and the cathode. A thickness of the anode substrate and a thickness of the cathode substrate are determined based on the curvature of the respective substrate, such that the one of the anode substrate and the cathode substrate with a larger curvature has a larger thickness.

A mobile terminal can include a display; a case including a conductive member having a first section and a second section, the first section having a first lateral surface and the second section having a second lateral surface; a dielectric member separating the first section from the second section; a gap formed between the first lateral surface and the second lateral surface; and a first cavity extending into the first lateral surface of the first section, in which the dielectric member fills the gap and the first cavity.

A housing of an electronic device includes a substrate defining an external surface and internal surface of the housing, at least one sidewall extending from the substrate, and abrasion-resistant members at least partly embedded in the substrate and extending beyond the external surface. The abrasion-resistant members may be formed from metal or ceramic. The substrate comprises a moldable matrix. The abrasion-resistant members are harder than the moldable matrix.
