摘要:
An optical projection apparatus comprising an illumination system, a light valve, an imaging system, a power supply circuit and a generator are provided. The illumination system with a color wheel is providing a light beam. The light valve is disposed on the transmitting path of the light beam for transforming the light beam into an image light beam. The imaging system is also disposed on the transmitting path of the image light beam. The power supply circuit is electrically connected to the illumination system and the light valve is connecting with an external power supply. The generator is electrically connected to the power supply circuit. The color wheel connected to the generator drives the generator to generate electric power. The electric power is transmitted to the power supply circuit and powers the optical projection apparatus. Consequently, overall power consumption of the optical projection apparatus is reduced.

An electric screen for a projector is provided. The electric screen utilizes a photo-electric conversion apparatus to convert received photon energy into electric energy and stores the electric energy in a storage battery. A motor is driven by the electric energy stored in a storage battery to extend or retract a screen. The electric screen further has a switch, the electric screen cooperates with the projector more efficiently.

An electronic control apparatus including motion sensors is integrated in a portable electronic device to responsively control a media content stored in the portable electronic device, in response to motion sensor signals to flip, zoom, displace images/pages of the media content displayed on a display field of a display thereof. Accordingly, a responsive control method includes the steps of: presetting a first threshold angle; sensing an first rotation angle of the portable electronic device to send out a first rotation sensing signal as a rotation of a yaw, pitch or roll of a portable electronic device detected by a sensing module including motion sensors; and receiving the first rotation sensing signal to calculate and determine whether the first rotation angle is greater than the first threshold angle to responsively control a media content stored in an electronic control apparatus be flipped, zoomed or displaced when the first rotation angle is greater than the first threshold angle.

A dongle includes: a receiver, for receiving a control signal which is not generated from a multi-touch panel; a processing unit, coupled to the receiver, for generating a multi-touch output signal corresponding to a multi-touch event according to the control signal; and a data port, coupled to the processing unit, for outputting the multi-touch output signal.
摘要:
An electric energy auxiliary device of transdermal drug delivery patch is provided which includes an upper electrode, a lower electrode, and a drug storage area between two electrodes, generating a kinetic energy in the pharmaceutical compound in the drug storage area toward the skin by a electric field between two electrodes. For the pharmaceutical compound with the same polarity, the pharmaceutical compound is pushed by the electric energy interacted with polar the pharmaceutical compound so as to deliver the drug the human body. The lower electrode generates an ion channel with electroporation on the surface of skin. By using the change of electric field on the surface of skin, a temporary ion channel is generated in the cells where the pharmaceutical compound enters the systemic circulation of human body via skin. This temporary ion channel allows large compound to pass into the skin of human body.
