Abstract: A method and an electronic device for enhancing efficiency of searching for a region of interest in a virtual environment are provided. The virtual environment includes a visible scene and an invisible scene. A picture-in-picture (PIP) is displayed in the visible scene as a directional guidance or distance hint related to the region of interest in the invisible scene, thereby saving time and enhancing efficiency of searching for the region of interest.

Abstract: A steel wire rope lock includes a lock housing, a steel wire rope having a first end and a second end, a first end connector for fixing tightly the first end of the steel wire rope, a second end connector for fixing tightly the second end of the steel wire rope and a lock fitted in the lock housing. The first end connector is inserted into the mouth of the lock housing. The lock is inserted in the other end of the lock housing. Then, the second end connector is inserted into the lateral hole of the lock housing, and the steel bead provided half in the round hole of the second end connector is compressed by the inner wall of the lateral hole to withdraw wholly in the round hole. When the second end connector being inserted more downwardly, the steel bead will be pushed outward by the spring in the round hole to be caught in the arc groove. Thus, the second end connector is firmly fixed in the lock housing.

Abstract: A steel wire rope lock has a lock housing, a lock fixed in a first end portion of the housing, and a steel wire rope having a first end fixed with a first end connecter and fitted around in a center hole of an annular member, and then connected with a second end of the housing. A second, end of the rope is fixed with a second connecter shaped tubular and having an annular groove near a bottom end, able to be inserted in a lateral hole of the housing to be kept immovable, i.e. locked by a deadbolt with a deep groove to fit around the annular groove of the second connecter if the lock is locked by a key.

Abstract: A U-shaped lock is provided which includes a straight tubular housing, a locking unit disposed within the housing, and a U-shaped shackle. The U-shaped shackle has one end provided with a bend stopper to fit in a shackle hole of the housing and the other end provided with a notch for receiving a flat rectangular portion of a dead bolt to lockingly engage or disengage the shackle. The locking unit includes a cylindrical member combined and rotating together with a lock cylinder. The lock cylinder has a key hole for insertion of a key for rotating the lock cylinder and a projecting block extending from a rear end of the lock cylinder and engaged in a hole of the cylindrical member. The dead bolt is moved forward or backward responsive to rotation of the key in the lock cylinder to cause the flat rectangular portion of the dead bolt to engage or disengage from the notch of the shackle.
