摘要： A parallel four-bar mechanism is disclosed, having the second and third bars being parallel to each other and having their opposite ends hinged to the first and fourth bars respectively. A stopping block is provided with a stopping slot, and a movable stopping pin is configured to be engageable with the stopping slot. When an actuating member drives the stopping pin to disengage from the stopping slot, the second and third bars are able to translation relative to each other; and when the actuating member drives the stopping pin into the stopping slot, the second and third bars are locked with each other, with the second and third bars being not able to translation relative to each other, and thus the whole parallel four-bar mechanism is locked in a preset angular position.

摘要： An expandable, implantable medical device, such as an intraluminal stent fabricated from polymeric materials, includes a plurality of elongated struts in consecutive series and alternating stress concentration junctions interconnecting ends of adjacent struts. When the stent is in an expanded condition, the adjacent struts form expanded substantial V-shapes and stresses are concentrated within the junctions. The junctions define pivot points for the respective attached, adjacent struts. Each of the pivot points is located substantially on a line bisecting the V-shapes formed by the struts, when the stent is expanded.

摘要： A pivotable support shaft for connecting a display with a base member and supporting the display is disclosed. The support is designed to enable the display to have different postures in working condition and package and transporting condition. For example, in the working condition, the screen of the display may be pivotable between a pitch-up angle of about 20° and a pitch-down angle of about −20°, and in the package and transporting condition, the screen of the display may be pivoted down to a pitch-down angle of about −90° where the screen faces downwardly to reduce the package size and improve the transportation stability.

摘要： 8PSK modulation methods and apparatuses are provided. In a first embodiment, product factors of symbol vectors and a coefficient of a shape filter are stored in a table and compressed by 8 times based on a law of a trigonometric function, wherein a method of table looking-up is used to replace a multiplication operation. In a second embodiment, all states of 8PSK modulation are stored in a table after shape filtering, and then the data of the states stored in the table are compressed based on a corresponding relationship of a law of a trigonometric function and an electrical level diversity, and then a table looking-up operation is performed. In a third embodiment, new modulated vectors are stored in a modulated phase table after simple 8PSK modulation and phase rotation, the modulated phase table is compressed by 4 times, and new modulated vectors are obtained by a table looking-up operation and data processing. Then, shape filtering is performed by utilizing a RAM coefficient filter. The 8PSK modulation methods and apparatuses are compatible with GSM systems and are capable of providing sufficient capability of data services and sufficiently extending a life cycle of prior GSM systems. It allows a service agent not only to save investment, but also to provide competitive services.
