Abstract: A portable electronic apparatus for selectively operating in normal mode and tablet mode includes a trigger device that generates a signal and a trigger value after being activated; a processing center that, in response to the signal, retrieves from the portable electronic apparatus a normal value corresponding to normal mode, and compares the normal value and the trigger value to obtain a comparison result; and an executing unit that, according to the comparison result, selectively executes normal mode and tablet mode.

Abstract: The present invention provides a pressure adjustable pillow, comprising a chamber made of an impermeable material and a cover member. The chamber is defined by a first direction, wherein the internal portion contains fluids. The chamber has three areas, and each area being not connected. Each area contains three sealed sacs along the first direction. Each sac is not linked and is provided according to a general shape of a head. Each sac has a valve. The cover member encloses the chamber. A user is allowed to adjust the amount the fluid in each sac, so as to adjust the pressure received by user's head to designated strength when the user sleeps on the user's side or in face-up position.

Abstract: A nail guiding mechanism of nailing gun composed of a gun body, a nail magazine and the nail guiding mechanism. The nail guiding mechanism includes a bottom board, a middle board and a top board. The bottom board is connected between the gun body and the nail magazine. The middle board is locked on the top face of the bottom board. The middle board is formed with multiple connecting holes for multiple locating members to fit therein. The locating members protrude from the top face of the middle board. The top board is mounted on the top face of the middle board. The top board is formed with multiple locating holes respectively corresponding to the locating members. The locating members are respectively passed through the locating holes to protrude from the top board. A press shank and a latch ring are pivotally disposed on the top board. When pressing down the press shank, the latch ring is tightly latched with the locating members to fixedly connect the top board with the middle board.

Abstract: A positioning unit is mounted on an electronic device and includes a catch member and a locking member. The catch member defines a gap which has a width that is reducible when the catch member moves from a non-catching position to a catching position and that is expandable when the catch member moves from the catching position to the non-catching position. The locking member has an engaging end extending into the gap. The locking member is operable to move the catch member from the non-catching position to the catching position and from the catching position to an urging position. The engaging end of the locking member engages the catch member when the width of the gap is reduced upon movement of the catch member to the catching position. The engaging end of the locking member disengages from the catch member when the width of the gap is enlarged upon movement of the catch member to the non-catching position.

Abstract: An active pixel sensor is used to replace a charge coupled device (CCD) image sensor. The active pixel sensor may be operated in a low voltage environment and the power consumption is lower than that in the conventional CCD image sensor and the CMOS active pixel sensor which is now developed by current industry. The active pixel sensor of the present invention has a lower cost and may be applied to a portable system.

Abstract: A hydraulic cylinder assembly comprising two hydraulic cylinders mounted on the frame of a climbing exerciser and connected by a control switch, said hydraulic cylinders each having an eye end piston rod inserted in an oil pipe, said eye end piston rod having a top end formed into an eye end respectively coupled with a L-shaped handlebar and a L-shaped pedal rod, and a bottom end formed into a screw rod fastened with a piston and locked by a locknut. By means of the aforementioned arrangement, the pedal and the handlebar of the same side are synchronously moved up and down.

Abstract: A position unit is mounted on an electronic device and includes a catch member and a locking member. The catch member defines a gap which has a width that is reducible when the catch member moves from a non-catching position to a catching position and that is expandable when the catch member moves from the catching position to the non-catching position. The locking member has an engine end extending into the gap. The locking member is operable to move the catch member from the non-catching position to the catching position and from the catching position to an urging position. The engaging end of the locking member engages the catch member when the width of the gap is reduced upon movement of the catch member to the catching position. The engaging end of the locking member disengages from the catch member when the width of the gap is enlarged upon movement of the catch member to the non-catching position.
