A mobile communication device includes a main body and a case. The case is rotatably received in the main body. The case is adapted to receive a battery and a subscriber identity module card. The battery is adapted to supply power to the mobile communication device. The subscriber identity module card is operable to store a service-subscriber key for identifying a subscriber of the mobile communication device. The case is operable to rotate relative to the main body, so as to expose the battery and the subscriber identity module card out of the main body.
Abstract:
An apparatus and method for processing an integrated circuit employing optical interference fringes. During processing, one or more wavelength lights are directed on the integrated circuit and based upon the detection of interference fringes and characteristics of the same, further processing may be controlled. One implementation involves charged particle beam processing of an integrated circuit as function of detection and/or characteristics of interference fringes. A charged particle beam trench milling operation is performed in or on the substrate of an integrated circuit. Light is directed on the floor of the trench. Interference fringes may be formed from the constructive or destructive interference between the light reflected from the floor and the light from the circuit structures. Resulting fringes will be a function, in part, of the thickness and/or profile of the trench floor. Milling may be controlled as a function of the detected fringe patterns.
Abstract:
A phase interpolation device and a slew rate control device thereof. The slew rate control device comprises a slew rate control circuit, source followers and a comparator. The slew rate control circuit receives clock signals and a control signal, and adjusts slew rate of the clock signals according to the control signal. The source followers each comprise an input terminal and an output terminal. The input terminals of the source followers are coupled to the slew rate control circuit to receive the adjusted clock signals, respectively. The output terminals of the source followers are connected together at a node. The comparator has a first input terminal coupled to the node, a second input terminal receiving a voltage reference, and an output terminal providing the control signal for the slew rate control circuit. The setting of the voltage reference is dependent on the desired slew rate of the adjusted clock signals.

The memory unit is received in the main body. The connector is electrically connected to the memory unit, the connector is secured to an end of the bending portion farthest away from the main body.
Abstract:
An autoloader system with modularization architecture and self-adaptive motion control ability for mass optical disks duplication includes four physical modules: a robot arm module with sensors and joints dedicates for delivering and picking up optical disks; an optical disk duplication tower has a number of optical drives in a stack, or a matrix for optical disk duplication; a motion control module has an embedded motion controller and a power source to synchronize the motion of robot arm and duplication; a platform module has a base frame to fix other modules and a user interface. Some disk stacks are situated on top of platform module. The use of a self-adaptive control algorithm, consisting of a Motion Strategy Database, Initial Process, Motion Planning Process, Motion Generation Process and Motion Monitor Process, to ascertain system configurations and components furthest satisfy the required flexibility for modifying/upgrading hardware or ever-changing user needs. The use of DC motors and self-correcting adaptive algorithm provides better versatility to disk copier systems than most commonly used stepper motors, even in the case of “short tray” wherein the tray does not fully extend out. The stand-alone design of present invention further makes the use and operation of the disk copier easier and friendlier.
