Abstract: The present invention relates to an infrared transmission protocol and more particularly to an infrared transmission protocol for wireless keyboard and PC remote controller. The transmission codes are grouped into four parts—key codes for keyboard, button codes for remote controller, mouse codes for keyboard, and mouse codes for remote controller. Key codes for keyboard are used to identify the MAKE and BREAK of keys on wireless keyboard. Button codes for remote controller are used to identify the MAKE and BREAK of buttons on PC remote controller. Mouse codes for keyboard and remote controller are defined separately. They are used to identify action of pointing devices on wireless keyboard and PC remote controller. Transmission codes are encoded into the RS232 format and transmitted through infrared wave at the baud rate of 1200. Each key packet for keyboard consists of two data-units. Each mouse packet for keyboard and each button and mouse packet for PC remote controller consist of three data-units.

By changing the composition of metals in the host, the crystal field thereof can be modulated, thereby altering the interaction force between the activator and the other components, and changing the wavelength of emitted colors. The present invention provides a white light-emitting device comprising a light emitting diode and above-mentioned. fluorescent powder. The LED emits purple-blue or blue light having a domination wavelength &lgr;D range from 430 nm to 500 nm. The fluorescent powder is excited by the purple-blue or blue. light emitted from-the LED to generate green-yellow light to orange-yellow light having a wavelength range from 560 nm to 590 nm and mixed with the light of LED to form white light.

Abstract: A burglarproof and event-recording apparatus for a vehicle comprises at least one camera arranged on the vehicle to surveil an environmental image for the vehicle and store the image to an image-storing and logic-controlling unit until an alarm flag is set to 1 by the image-storing and logic-controlling unit. The apparatus will raise alarm and set the alarm flag to 1 once the vehicle is intruded. At this time, the image is stored in a currently-used memory block of the image-storing and logic-controlling unit and the intrusion condition is formed to the vehicle owner.

Abstract: A method for enhancing printing quality to process the picture and textual data in an image properly such that both the picture and textual data can be clearly printed. The inventive method can treat the image data to be printed in a real time fashion and while the entire image data is not required. In the inventive method, the difference of gray level is reallocated by error diffusion method to render the edge more smooth and clear.

A lamp radiating fan inhales an air blowing toward the lamp center and a radiating fan drains the air out it of the second ventiduct space to carry away a heat generated by the light source.

Abstract: A two-dimensional auto compensated multi-axis tolerance adaptive system used in the cartridge carrier of an inject office machine is constructed to include a carrier unit, a reciprocation mechanism, and a driving mechanism, the carrier unit having a clearance sensor and a bias sensor, the driving mechanism including a rotating unit fastened pivotally with the carrier unit and a lifting unit coupled to the reciprocation mechanism for a linear movement for enabling the plane of rotation of the rotating unit to form with the straight lifting line of the lifting unit a X-Y plane and Z-axis space coordinates system. By means of the detection and scanning of the clearance sensor and the bias sensor, the ink cartridge carrier actively controls the optimum printing clearance between the ink jet nozzle and the media.

Abstract: A phase rotary disk motor switching module employs anchor notches located on the peripheral rim of a rotary disk mounted on a motor to couple with a retaining element to enable the rotary disk to rotate in only one direction and define a plurality of phases for the rotary disk. Every phase has a driven gear coupled with the motor for transmitting output power. Motor power may be switched to a plurality of phases of output positions to maximize utilization of a single motor.

Abstract: The present invention relates to a stroke-limited key structure and a keyboard including the key. The key structure includes a base, a scissors-shaped member, and a cap. The scissors-shaped frame is disposed on the base, and the cap is disposed on the scissors-shaped member. The scissors-shaped frame includes a first frame and a second frame that is rotatably coupled to the first frame. The first and second frames include a first protrusion and a second protrusion. The stroke of the key is limited by using the engagement between the first and second protrusions.

Abstract: A scanning apparatus capable of automatically powering on is disclosed. The scanning apparatus includes a main body, a lid, a carriage inside the main body, and a scanner board. The lid is hinged to the main body. The scanner board includes a scanner frame and a glass plate mounted in the scanner frame and extending under the scanner frame. The scanner board further includes an opening on the scanner frame. The opening exposes the glass plate thereunder and the opening is substantially above the start point of the carriage. Therefore, the auto power on scanning apparatus has the advantage of preventing dust from dropping into the interior of the main body. Also, extra care and cost paid to the fragile projected pattern can be eliminated.

Abstract: A searching system employs a global positioning system (GPS) and a wireless communication system to enable a second transceiver to trace the distance and the directions of a plurality of first transceivers. The first transceiver can automatically call the second transceiver user when the user of the first transceiver is at rest in excess of a predetermined interval or has a body temperature lower than a critical value. The user of the first transceiver can push an emergency button on the first transceiver to call the user of the second transceiver for help.

Abstract: An interlocked type paper collection support board of printer includes a paper-out board, an extension board, and a half stroke mechanism. The paper-out board is retractably installed on a main body of a printer. The extension board is also retractably installed on the paper-out board.
