The present invention discloses a method for image pickup and an image pickup device using the same. The image pickup device includes a lens, an image-processing program, and a user interface. The lens is utilized to obtain a main image by shooting an object. The image-processing program divides the main image into a plurality of sub-image blocks, computes the resolution of every sub-image block, and compares each resolution with a threshold. The user interface displays the compared result of each sub-image block to indicate if the lens and the object are parallel.

Method for determining clear image using an image pickup device

An optical image system includes an image pickup module, a swinging mechanism, a first swinging calibration element and a second swinging calibration element. When the optical image system is tilted because of handshaking, the image pickup module is swung by the swinging mechanism. At the same time, the first swinging calibration element and the second swinging calibration element detect whether the image pickup module is swung to an ideal position where the handshaking problem is eliminated.

The present invention provides a power strip having a surge protective circuit. When a surge is inputted into the power strip, the surge is subject to two-stage suppressions so as to protect the electrical appliances which are electrically connected to the power strip. The surge protective circuit of the power strip includes a first surge protective device, a buffer conductive device and a second surge protective device. The buffer conductive device is relatively small-sized and cost-effective in comparison with the bulky inductor used in conventional power strip.

Power strip having surge protective circuit

A power strip device includes a power plug, a master power outlet, multiple slave power outlets and a control circuit. The control circuit includes an inductor, a reed switch and a switching circuit. Under the control of the control circuit, the power strip device allows the slave power outlets to be automatically turned on or off simultaneous with the master power outlet being turned on or off.

A surge protection circuit includes a first surge absorber and a first conducting wire. The first surge absorber has an end electrically connected to a first power signal line. The first conducting wire is covered with insulating material and electrically connected to the other end of the first surge absorber and a second power signal line. The first surge absorber absorbs energy of a surge signal in a short-circuit state when the surge signal flows through the first power signal line or the second power signal line. Afterwards, the first conducting wire which is connected to the first surge absorber in series is damaged by the energy of the surge signal to enter an interrupted state, thereby protecting a signal processing device which is electrically connected to the first power signal line and the second power signal line.

A surge-protected hub applied to set up an AC line networking system and used for eliminating the surge problem is provided. The surge-protected hub includes a housing; a plurality of connectors mounted on the housing and electrically connected to an alternating-current power source for independently establishing connections to power lines for power transmission or network lines for networking signal transmission; and a surge-protected device disposed in the housing and arranged upstream of the plurality of connectors for filtering out surge signals that are received from the alternating-current power source while allowing networking signals having a frequency range lying in the frequency range of the surge signals to pass therethrough.

Surge-protected networking power strip

A bi-directional low-pass filter for use at a user end or an office end in a communication network is disclosed. By providing compensation and high-band attenuation circuitry, the low-pass filter exhibits an improved attenuation value in high-band and a general attenuation value in a low-frequency band. The satisfactory attenuation performance in the high-frequency band minimizes the signal interference of a high-band communication terminal with a low-band communication terminal in the communication network. Further, by providing symmetric input/output circuitry, the low-pass filter can be operated reversibly.
