Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: A storage method and a search method for mark events on two-dimensional space are provided. First, an event and a corresponding coordinate thereof are retrieved. Next, calculation on the coordinate of the event is performed to generate an index representing a bucket position in a storage device. Next, whether or not there is any existing search tree stored in the bucket position is judged, and then the event is inserted into a linked list of a node of the search tree stored in the bucket position according to a judgment result. Besides, when a range on the two-dimensional space is designated, corresponding nodes in the search tree are rapidly accessed according to the index obtained by a hash function, and further by application of pointers pointing to the bucket position having the search tree stored therein and by real-time return of search result, the search speed is high.

Abstract: A method for grouping wireless devices and an apparatus thereof are provided. First, the feature values of a plurality of access points (APs) detected by a wireless device are received, wherein these APs are designated as a first set, and the feature values of the APs constitute a feature vector. A first grouping process is performed to the wireless device according to the first set, which allocates the wireless device to an appointed clustering factory. A second grouping process is performed to the wireless device according to the feature vector, which divides all of the wireless devices within the appointed clustering factory into a member group or a noise group. Eventually, the grouping result is transmitted to the wireless device.

Abstract: The present invention relates to a high linear enhancement-mode heterostructure field-effect transistor. More, the present invention uses an InGaAs channel structure with a linear change, and integrates an adjusting effect of working region corresponding to the threshold voltage of the element. It not only directly provides a complementary structure for the conventional depletion-mode element to select, but also increases the range of the gate voltage swing. More, some important characteristics, such as current driving capacity, transconductance gain, linear amplification, and high speed operation can be largely improved. More particularly, E-mode working element has a low static power. Further, the present invention also has a high stop frequency characteristic of the high speed element from the composite semiconductor, and it can be applied to the microwave push-pull amplification circuit.

Abstract: A mounting plate for an auxiliary lock mechanism includes at least one assembling hole and at least one adapter combined therewith. The assembling hole has a neck portion and the adapter correspondingly has a slit adapted to snap-connect to the neck portion of the assembling hole. An engaging length of the adapter is permitted adjusting to extend into a through hole of a latch unit for positioning purpose. In addition, a shorter screw member is selectively connected the adapter with the mounting plate.

Abstract: A two-way assembling device for the auxiliary lock includes a monolithic assembling plate consisting of a first side and a second side. The first side forms a first engaging upright portion with a first diameter while the second side forming a second engaging upright portion with a second diameter. A door plank has an assembling hole with a first diameter or a second diameter which is able to engage with either of the first engaging upright portion or the second engaging upright portion. Subsequently, the monolithic assembling plate is secured to the assembling hole of the door plank. Finally, a rose escutcheon and a doorknob are secured to the door plank through the monolithic assembling plate.
