Abstract: A method for obtaining and processing image data by using a medical visual aid system including a monitor and an endoscope configured to be inserted into a body cavity and including an image capturing device and a light emitting device, the method including illuminating a field of view of the image capturing device with the light emitting device, capturing the image data using the image capturing device, providing a non-linear scaling model adapted to the body cavity, adjusting the image data by applying the non-linear scaling model such that adjusted image data is formed, and presenting the adjusted image data on the monitor.

Abstract: Portable communication devices are provided. A portable communication device includes a housing, an antenna, and a push button. The housing includes a first receiving portion and a second receiving portion. The antenna is detachably disposed in the first receiving portion. The antenna includes a first engaging portion. The battery is detachably disposed in the second receiving portion. The battery includes a second engaging portion. The push button is disposed in the housing and includes a third engaging portion and a fourth engaging portion. The third engaging portion movably engages with the first engaging portion to fix the antenna to the housing. The fourth engaging portion movably engages with the second engaging portion to fix the battery to the housing.

Abstract: A portable electronic device has a body, a cover connected movably to the body, and able to move between a first position and a second position relative to the body, a first magnetic component set in the body, and a rotating unit connected to the body. When the cover leaves the second position, the first magnetic component provides a first magnetic force to the rotating unit and drives the rotating unit to rotate in a first direction to push the cover to the first position.

Abstract: An electronic device includes a plurality link bars, a plurality of magnetic devices, a first module and a second module connected to the first module in a slideable manner. The magnetic devices are disposed at connecting nodes where the link bars are connected to each other. One connecting node of the link bars is fixed at the first module of the electronic device, and another connecting node of the link bars is fixed at the second module of the electronic device. The first and second modules are open and closed in a semi-automatic manner based on magnetic force formed between the magnetic devices disposed at the connecting nodes.

Abstract: The present invention relates to a portable communication apparatus, including a body, a first portion and a second portion. The body has a first end and a second end. The first portion is pivotally connected to the first end and the second portion is pivotally connected to the second end. The body further has a surface.
