Abstract: A hinge apparatus and a portable terminal are provided including a pair of housings configured to open or close and one of the housings is positioned in parallel with a side of the other to rotate the portable terminal about 90° according to user preference. Thus, the user can enjoy the horizontal view of a screen of a display device. Consequently, the user can conveniently watch the screen provided through a multimedia service. The hinge apparatus that rotates a housing such that the housing is positioned in parallel with a side of the other housing provides a driving force exerted in a direction that is the same as or opposite to a direction the housing rotates to implement a semi-automatic operation and provide user convenience.

Abstract: A trans-reflective type In-Plane Switching (IPS)-LCD device capable of implementing a single gap and a wide viewing angle, and minimizing an occurrence area of disclination at an interface between a transmission region and a reflection region, and a method for designing the same. First and second alignment layers have characteristics to allow LC in a transmission region can be aligned in the same direction as a transmission axis of a lower polarizer. A third alignment layer is aligned so that the LC in the reflection region can be twisted from a lower side to an upper side with a predetermined twisted angle (?). Here, the twisted angle (?) of the LC in the reflection region, and an angle (?) between an alignment direction of an uppermost LC in the reflection region and the transmission axis of the upper polarizer are set so that optical reflectivity in the reflection region is ‘0’ when the LC is not driven.

Abstract: The present disclosure generally relates to devices for covering an ear, and more particularly to such devices that are self-attaching and used for sound optimization, such as noise reduction. More specifically, the present disclosure is directed to hearing protection muffs that comprise a sound attenuating cap, a self-attachment member for engaging the sound attenuating cap to the ear of a user, and optionally a sealing member. Advantageously, the muffs of the present disclosure have good sound attenuating properties and do not require a band or other external attachment device to secure the muffs to the ear.

Abstract: A hearing protection device for a human ear. The device has an arm that clips about the pinna. A plug member caps or enters ear canal.

Abstract: A hinge apparatus for connecting a first housing and a second housing of a portable terminal is provided. The hinge apparatus includes a hinge housing and a damping member. The hinge housing is connected to the second housing and has an internal wall formed with one or more guide grooves extending in a circumferential direction of the hinge housing. The damping member is rotatably received in the hinge housing and rotates as the second housing rotates. The damping member has one or more frictional projections. In a first section corresponding to the position where the second housing is folded onto the first housing, the frictional projections contact the internal wall of the hinge housing. Similarly, in another section corresponding to the position where the rotation of the second housing is stopped after rotating away from the first housing, the frictional projections also contact the internal wall of the hinge housing.
