Abstract: An illumination system including an excitation light source module configured to emit an excitation beam, a wavelength conversion device, and a light-splitting unit on a transmission path of the excitation beam and between the excitation light source module and the wavelength conversion device is provided. The light-splitting unit includes a transparent substrate and a first optical film with a hole through which the excitation beam is transmitted to the wavelength conversion device. A wavelength conversion area and a diffusion area of the wavelength conversion device cut into the transmission path by turns. The wavelength conversion area converts the excitation beam into a conversion beam transmitted to the light-splitting unit. The diffusion area reflects the excitation beam to the light-splitting unit; the first optical film reflects the excitation beam coming from the diffusion area. Wavelengths of the conversion beam and excitation beam are different. A projection apparatus is also provided.

Abstract: A cooling system for a projector is provided and disposed in the projector. When a sensing temperature of the projector sensed by a thermal sensor of the cooling system is higher than a maximum temperature, a control module controls a fan to increase a rotation speed. When the sensing temperature of the projector sensed by the thermal sensor is lower than a minimum temperature, the control module controls the fan to decrease the rotation speed. As a result, the temperature of the projector is maintained within a proper range.

Abstract: A system for exposing a flexographic printing plate with light includes a light-providing subsystem and a reflector around the light-providing subsystem. The reflector includes a body and a plurality of miniature mirrors on an interior of the body arranged to reflect light generated by the light-providing subsystem to exit the reflector at angles integrated between 0 degrees and a selected angle, such as 30 degrees. As a result, the shoulder angles of features on the flexographic printing plate are controlled within a selected range of angles, such as 0 to 30 degrees.

Abstract: An exposure system is provided that surrounds a photopolymer on a rotating cylinder ablation system. The exposure system linearly follows the ablation source and operates to expose the ablated (masked) plate with high intensity illumination from all sides so as to continuously expose all points on the photopolymer.

Abstract: An apparatus utilizing non-coherent light digitally exposes a light-sensitive medium. The apparatus includes a non-coherent light source such as a wall stabilized plasma-filled capillary lamp, a reflector positioned proximate the non-coherent light source to reflect actinic radiation, a modulator positioned to selectively transmit the reflected actinic radiation and the light sensitive material positioned proximate the modulator to receive modulated actinic radiation.

Abstract: An adapter and signal transmission cables for hands-free telephone system including a mobile telephone, car audio equipment such as a cassette recorder and a mobile telephone adapter. The mobile telephone adapter includes an adapter body, which can be pushed inside the cassette recorder; a hands-free microphone; a first signal transmission cable for connecting the adapter body and the mobile telephone; and a second signal transmission cable for connecting the hands-free microphone and the mobile telephone. The adapter body has a housing that resembles a cassette tape externally and a magnetic recording head installed inside. One end of the first and second signal transmission cables are joined together and connected to a plug, and the plug is capable of plugging into the voice input/output socket of the mobile telephone. When the mobile telephone picks up incoming voice signals, the signals will be transmitted via the adapter to the cassette recorder, which is then broadcast out through its loudspeakers.

Abstract: Apparatus and related methods for continuous long-term non-invasive measurement of the pressure of a pulsatile fluid flowing through a flexible tube, particularly human arterial blood flow, is disclosed. Specifically, the apparatus provides a continuous calibrated pressure measurement by first undertaking a "calibration" phase comprised of determining the pressure at various pre-defined conditions of flow and, in reponse thereto, ascertaining the values of a plurality of coefficients each of which is associated with a corresponding term in a pre-defined function that characterizes fluid pressure in relation to pulsatile displacement of the wall of the tube; and second, undertaking a "continuous monitoring" phase comprised of determining each subsequently occurring pressure value as the pre-defined function of each corresponding pulsatile wall displacement value, and re-initiating the calibration phase at the expiration of pre-defined time intervals which adaptively change based upon current and prior results.
