Abstract: A system for detecting and cleaning indoor air pollution includes gas detection devices and filtering devices. The gas detection devices are adapted to detect a qualitative property and a concentration of an air pollution and output an air pollution data to perform an intelligent computation. The filtering devices are physical-typed or chemical-typed for filtering the air pollution. The filtering devices include one or more movable filtering devices, and the movable filtering device includes a gas detection device. After the intelligent computation is performed to locate an air pollution location, a control command is transmitted to the movable filtering device selectively and intelligently, and the movable filtering device receives the control command and is moved to the air pollution location. Therefore, the movable filtering device allows the air pollution data to approach to a non-detection state, thus a gas in the indoor space is cleaned to a safe and breathable state.

Abstract: A gas detection and cleaning system for a vehicle is disclosed and includes an external modular base, a gas detection module and a cleaning device. The gas detection module is connected to a first external connection port of the external modular base to detect a gas in the vehicle and output the information datum. The information datum is transmitted through the first external connection port to a driving and controlling module of the external modular base, processed and converted into an actuation information datum for being externally outputted through a second external connection port of the external modular base. The cleaning device is connected with the second external connection port through an external port to receive the actuation information datum outputted from the second external connection port to actuate or close the cleaning device.

Abstract: A blood pressure device includes a first blood pressure measuring device, a second blood pressure measuring device, and a controller. The first blood pressure measuring device is to be worn on a first position of a wrist so as to obtain a first blood pressure information of the first position. The second blood pressure measuring device is to be worn on a second position of the wrist so as to obtain a second blood pressure information of the second position. The controller is electrically coupled to the first blood pressure measuring device and the second blood pressure measuring device so as to adjust tightness between the expanders and the user's skin, respectively. The controller receives, processes, and calculates a pulse transit time between the first blood pressure information and the second blood pressure information, and the controller obtains at least one blood pressure value based on the pulse transit time.

Abstract: Disclosed is underwear with the function of preventing the garment from shifting, the underwear having a waist opening, two leg openings, a crotch, and a waist ring belt adjacent the waist opening. The main feature is that the waist ring belt includes first and second belt parts, and a pre-fold line between the first and second belt parts, so that the first belt part can be selectively folded and abutted against the outside of the second belt part. The outside of at least one of the belt parts has a frictional anti-slip component. Due to the different folding states of the first belt part, the frictional anti-slip component can be formed in a hidden or exposed state. In the exposed state, the anti-slip component abuts against the garment at the outside of the waist ring belt. In this state, the frictional anti-slip component produces friction to prevent shifting.

Abstract: A non-sewing corset with different curvature and elasticity is disclosed, having a tubular knitted main body that defines a pull-through space. A reducing portion shrinking inward is formed in the middle section of the tubular knitted main body so that the corset has an hourglass-shaped structure. Two sleeving portions are formed on the upper and lower sides of the tubular knitted main body. The reducing portion uses a knitting method different from the two sleeving portions, with its elasticity higher than the elasticity of the two sleeving portions, so that the reducing portion can have a reinforced binding on the predetermined position of the body. As a result, the corset product alone can achieve the binding and body-sculpting effect of an additional vest.

Abstract: A method for modifying plunge shaving cutters aims to modify a plunge shaving cutter through a grinding tool. The plunge shaving cutter has a plurality of helical teeth spaced from each other. The helical teeth have a machining-intended side. The method of modification includes the steps of: positioning the plunge shaving cutter on a gear forming grinder with the machining-intended side in contact with the grinding tool; moving the plunge shaving cutter according to a variable rotation amount and a first variable movement amount; moving the grinding tool according to a second variable movement amount to perform a helical movement against the plunge shaving cutter and a modification process on the machining-intended side. Thus the existing gear forming grinder can be applied to the plunge shaving cutter for machining to improve machining speed.

Abstract: A flexible freight bag includes a flexible base unit having first and second panel halves that are interconnected to form a flexible base panel, and a hanging strap assembly connected to the flexible base unit. The first and second panel halves have adjacent inner end portions that are fastened to each other to form a seam across the flexible base panel. A fastener unit is attached to the inner end portions of the first and second panel halves and is operable to be detached from at least one of the inner end portions so that the inner end portions are separable from each other.

Abstract: A circular knitted head cover, used to cover the user's bead, has a long cylindrical cap, integrally circular knitted, flexible, and in the shape of a hollow cylinder. The relative two ends of the long cylindrical cap are respectively formed with an upper cap opening and a lower cap opening. At least one eye through-hole is provided, being an opening integrally knitted on one side of the long cylindrical cap. The eye through-hole enables exposure of the user's eyes when wearing the head cover. An interlaced mouth and nose vent is provided in the shape of interval holes, integrally knitted on one side of the long cylindrical cap and located on a position spaced from the eye through-hole. The interlaced mouth and nose vent enables ventilation of the user's mouth and nose when wearing the head cover.

Abstract: A woven product contains luminescent yarns that are formed by fluorescent threads giving off luminescence upon receiving light, or contains luminescent yarns that are formed by luminous threads giving off luminescence at night by themselves. These two luminescent yarns can be used in a separate or mixed manner to thereby make the portions of woven products containing such yarns luminous at night or under dark circumstance by themselves. In this way, the woven product not only can present luminous beauty or serve as a warning signal, but also can be flat and smooth on the surface.

Abstract: A sheet-by-sheet paper feeding structure includes a sheets separating plate and a pressure plate. When a pile of paper is fed into the paper feeding structure, a front end of the pile urges against the sheets separating plate, which is in turn pressed by a press leg of the press plate above so that the sheets of paper are checked from displacing forwardly. The press plate further includes elastic plates having elastic plate press legs that help keep the sheets of paper flat and stable during feeding. A lowermost sheet of the pile is in direct contact with a roller of a facsimile machine or printer or the like. When the roller rolls forwardly, it will only bring the lowermost sheet to advance forwardly while the rest of the pile is being checked by the sheets separating plate.
