Abstract: An integrated diagnostic system includes interface connectors to connect to a plurality of instruments/instrument modules, including engine analyzers, gas analyzers, oscilloscopes, scanners, network connections, and/or other desired peripheral modules. These modules advantageously interface to the system through diverse parts, connections and with various protocols. The system may connect to a network, wired or wireless, for interfacing among processors and modules, and with an internet connection for interaction with remote resources including databases and expert systems.

Abstract: A computer system and method for preventing burnout of a Central Processing Unit (CPU). The computer system includes a CPU, a temperature sensor, a Direct Current to Direct Current (DC-DC) transformer, a hardware monitor and an ATX power supply. The CPU serves to execute computer programs. The temperature sensor is adjacent to or directly attached to the CPU for monitoring the operating temperature of the CPU. The DC-DC transformer is coupled to the CPU for providing CPU source voltage. The hardware monitor is coupled to the temperature sensor and the DC-DC transformer for monitoring the operating temperature and the source voltage of the CPU. The ATX power supply is coupled to the hardware monitor and the DC-DC transformer and controlled by a Post Power-Triggering Signal. When the operating temperature or the source voltage exceeds a permitted range, the hardware monitor sends a Post Power-Triggering signal to the ATX power supply to cut its output power off.

Abstract: A dust-proof device for a solid integration rod in projecting apparatuses is provided in the invention. The solid integration rod has a layer of metal reflecting film with a certain length in axial direction. The layer of metal reflecting film is coated on the circumferential outer surface at an end of the solid integration rod that is adhered to the dust-proof element of the dust-proof device. The metal reflecting film is provided so that if a flared portion of the adhesive occurs after the dust-proof device is adhered to the solid integration rod, the metal film will still reflect the light normally, and the light energy will not be lost through the flare portion.

Abstract: The invention discloses a solid rod dust-proof structure for projecting apparatuses. The solid rod includes an incident-beam surface and an outgoing-beam surface. The dust-proof structure includes: a housing provided with a first chamber and a second chamber connecting each other wherein the cross section of the second chamber is greater than that of the first chamber. The first chamber contains the solid rod, and a stopping portion is installed on the opposite end of the second chamber for stopping the solid rod; and a dust-proof plate being a transparent plate is contained in the second chamber to completely cover the outgoing-beam surface of the solid rod. Using the above structure, the outgoing-beam surface of the solid rod can be completely covered by the transparent dust-proof plate so that the structure is free from dust and the light transmitting through the outgoing-beam surface will not be blocked.

Abstract: Improved locking sleeve assembly is intended for use on a knock-down display shelf which is made up of four supporting pillars, multiple inner sleeves, rest boards, a top board and a plurality of retaining caps. Each locking sleeve assembly is made up of a separable inner locking sleeve and a retaining cap which has a roundly flanged bottom and a hollow central tubular portion provided with a tapered inner surface. On the circular flange of each retaining cap are disposed a number of counter sunk screw holes. At each corner of a rest board is disposed a counter sunk through hole in which a bottom flanged retaining cap can be placed and fixed in place by screws engaged with the screw holes on the circular flange. Each supporting pillar has a plurality of equally spaced peripheral grooves so as to permit halves of the separable locking sleeves, each having a peripherally extended rib on the inner surface, to be selectively engaged with the grooves of a supporting pillar at various levels.

Abstract: A table with adjustable shelves including four supporting rods, several collars, several retaining boards, a cover board, several supporting beams and several bridge beams. Each corner of the retaining board is formed with an arch recess. The supporting beam includes a linkage each end of which is connected with a C-shaped conic fixing sleeve. Two sides of top edge of the linkage are respectively formed with two dented section. When assembled, from lateral upper sides of the collars, the C-shaped conic fixing sleeves of the supporting beams are downward fitted onto the supporting rods and engaged with the collars fitted around the supporting rods. The bridge beams are bridged between the linkages of the supporting beams with the ends of the bridge beams inserted in the dented sections thereof. The retaining board is positioned between the supporting rods and rested on the supporting beams and the bridge beams.

Abstract: An illuminating coaster includes an upper member, an intermediate member, a lower member, an illuminating assembly arranged between the upper member and the intermediate member and including a first conducting member, a second conducting member, and batteries, the first conducting member being fixedly mounted on an inner side of the upper member, the first conducting member being fixedly mounted on an inner side of the upper member, the second conducting member being provided with a light-emitting diode, the batteries being disposed between the first and second conducting members, whereby when a glass is put onto the coaster, the upper member will be pressed downwardly to make the first conducting member contact the batteries thereby forming a closed circuit and therefore causing the light-emitting diode to give light through a bottom of the glass.

Abstract: A foldable hanger of the present invention mainly comprises a hook portion, a frame and two shoulders. The hook portion is formed with an extended cylindrical post at its lower portion, from which extends a notch from half way of the cylindrical post down to its bottom, and two flanges at its two sides of the notch. The frame has an upper and a lower hollow pipes with a board formed inbetween the two pipes. Both of the upper and the lower pipes have teeth integrally formed in the hollow bodies and a block ring placed inside of each end of the two pipes. The board is integrally formed with the two pipes having a recess being shaped like the hook in reversed position located underneath the cut portion of the upper pipe each of which has two flat plates extended upwardly from the cut ends therefrom and each of which further has two semi-circle plates extended outwardly from the top of the flat plate towards the two ends of the upper pipe respectively.
