Abstract: The present invention provides a control device for an isolated converter, including a comparison module, which receives a load percentage of the isolated converter, compares the load percentage with a first preset threshold and a second preset threshold, and outputs a comparison result; and an adjustment module, which receives the comparison result and adjusts a switching frequency of a switching transistor of the isolated converter based on the comparison result, wherein when the load percentage is not greater than the first preset threshold value, the switching frequency is set to a first frequency value to prevent magnetic saturation of a transformer of the isolated converter, and when the load percentage is greater than the second preset threshold value and in a stable state, the switching frequency is set to a second frequency value, so that the temperature of the isolated converter does not exceed the maximum allowable temperature, wherein the first preset threshold is less than or equal to the second

Abstract: The present invention discloses a composite wood processing method and equipment for unidirectionally pressurizing and filling wood. Original ducts of wood which transport water and nutrients are used primarily to make wood into the composite wood by a unidirectional pressurization method. The processing method puts the wood longitudinally into a pressure vessel, allowing front end parts of the wood to be connected with atmosphere. Next, the wood is sealed with the pressure vessel and a solution is pressurized and filled into the pressure vessel, such that the solution can enter into the wood through the ducts of wood that transport water and nutrients. The composite wood processing method utilizes the original ducts of wood transporting water and nutrients; therefore, the composite wood can be formed by lower pressure and with a saving of energy, thereby having multiple advantages of fast processing, stability, labor saving and time saving.

Abstract: An imaging method for microcalcification displays microcalcification distribution by acquiring and overlapping a photoacoustic image of microcalcification and an ultrasonic image of tissue. The image acquired by the present invention, in comparison to images acquired by ultrasonic and X-ray mammography, has advantages in no speckle noises, higher optical contrast, higher ultrasonic resolution, and so on. The present invention also has advantage in safety by adopting a light source having no ionizing radiation. An imaging method for diagnosing breast cancer is also herein disclosed.

Abstract: Hermetically sealed enclosures and constructions are disclosed for use in endoscopic systems, particularly endoscopic systems with electronic imaging and illumination systems in the enclosures. Compound optical windows are also disclosed for use in the systems. The compound optical windows may have separate panes for an imaging system and an illumination system, and contrast-reducing optical boundaries are between panes.

Abstract: A global positioning system (GPS) having instant notification of vehicle status function includes a GPS satellite signal-receiver module (11), a satellite signal-receiving antenna (12), a checking signal processing circuit (20) and a wireless communication module (30). The GPS satellite signal-receiver module (11) acquires an abnormal status of vehicle message from the checking signal processing circuit (20), and via the satellite signal-receiving antenna (12) receives vehicle position data. After processing, the wireless communication module (30) sends the data to a remote host (62) to provide the instant notification of vehicle status. Therefore, the GPS having instant notification of vehicle status function can effectively simplify a module of vehicle theft and security system circuits and components, so as to reduce cost.

Abstract: Sterilizable electronic video cameras for an endoscope are provided. The electronic video camera comprises an enclosure, a lens cell, a lens cell holder, an image sensor, a motorized focusing system, and switch control. The enclosure comprises a housing and a cover, the housing defining a cavity therein. The cover has a window disposed therein, the housing and cover adapted for hermetic coupling. The lens cell is slidably disposed in the lens cell holder. The image sensor is in optical communication with the lens cell and window. The motorized focusing system is adapted to axially reciprocally move the lens cell relative to the lens cell holder controlled by the switch. The switch control is activated external to the enclosure and is hermetically sealed therewith. The lens cell, lens cell holder, image sensor, and the motorized focusing system, as an assembly, are coupled to the cover and disposed within the cavity.

Abstract: A torque-indicating wrench includes a wrench body with a head to engage and turn a workpiece, and a stem having an inner peripheral wall with longitudinal and transverse wall segments. A strainable body made of a material with an elasticity modulus smaller than that of the stem has an outer peripheral wall which includes front and rear bending force transmitting areas in engagement with and stretchable relative to the front and rear regions of the longitudinal wall segments, and two gage carrying regions and front and rear end regions that are spaced apart from the longitudinal and transverse wall segments, respectively. A strain gage unit is attached to one of the gage carrying regions to detect change in resistance values corresponding to stretching deformation of the strainable body for processing by a processing circuit so as to obtain a value of torque applied to the workpiece.
