The present invention discloses an electronic device with object guiding function and the method thereof. In one embodiment, the electronic device includes a view window area, via which a user may watch a view. The electronic device may determine whether an object is located in the view window area when the user inputs the position of the object, and may further show an object indicating message or an object guiding message according to the determination result. Therefore, the electronic device is able to provide the user with short distance guiding function. In another embodiment, the electronic device may also show information related to the object located in the view window area, such as information about every mountain range, constellation, user's friends, or specific landmark that is located in the view window area.

A disk drive is disclosed comprising a disk, a head, and control circuitry comprising a servo control system operable to actuate the head over the disk. A plurality of disturbance signals is generated in response to a vibration. A plurality of correlations is generated in response to each disturbance signal and an error signal of the servo control system. At least one of the disturbance signals is selected in response to the correlations. A feed-forward compensation value is generated in response to the selected disturbance signal, and the feed-forward compensation value is applied to the servo control system to compensate for the vibration.

A disk drive comprises a disk, an actuator arm and a servo controller using a position error signal to generate a controller output signal to control the actuator arm. A plant mechanically models at least a portion of the disk drive, receives a control command to which an unknown disturbance is added and generates a plant output. A disturbance observer (DOB) uses the control command and the plant output to generate a delayed and estimated version of the disturbance. The DOB comprises a Q filter having a selected center frequency. A perfect phase cancellation filter (PPCF) is configured to receive the delayed and estimated version of the disturbance, to reject selected disturbances and to align the desired attenuation frequency with the selected center frequency. The output of the PPCF is subtracted from the controller output signal to generate the control command.

A single piece light guide is disclosed herein. The single piece light guide may include a light rod and a lens. The single piece light guide may be formed using injection molding. The light guide may have one or more regions between the light rod and the lens. A housing may be provided for the light guide. The housing may have an opening that physically supports the light rod. Therefore, the light rod may be secured into place, which may prevent misalignment during use. The one or more regions between the light rod and the lens may assist in assembling and holding the light guide in the housing.

An array of microbumps with a layer or coating of non-superhydrophobic material yields a superhydrophobic surface, and may also have a contact angle hysteresis of 15 degrees or less. A surface with such an array may therefore be rendered superhydrophobic even though the surface structure and materials are not, by themselves, superhydrophobic.

A mobile device includes a touch screen, an unlocking key, a function key and a processor. The unlocking key transmits a first command to the processor when pressed. The function key transmits a second command to the processor when pressed.The processor is coupled to the touch screen, the unlocking key and the function key. The processor operates in a standby mode and is configured to: display a first user interface on the touch screen when the processor receives the first command; display a second user interface on the touch screen when the processor receives the second command; switch to a normal work mode when the first user interface of the touch screen detects that the touch gesture is an unlocking touch gesture; and switch to a special work mode and enable a first function when the second user interface of the touch screen detects a first touch gesture.
