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: A heat exchanger of a ventilation apparatus including a first positioning disk, a second positioning disk, a fixing module and a plurality of guiding pipes is disclosed. The first positioning disk has a first fixing portion and a plurality of first positioning portions. The second positioning disk has a second fixing portion and a plurality of second positioning portions. The fixing module connects with the first and second fixing portions of the first and second positioning disks to separate the first and second positioning disks by a distance. The plurality of guiding pipes is arranged between the first and second positioning disks. A first end of each guiding pipe couples with a respective one of the first positioning portions of the first positioning disk, and a second end of each guiding pipe couples with a respective one of the second positioning portions of the second positioning disk.

Abstract: The present invention relates to a cooling module retentioner, which includes a fixing base and a flexible frame. The fixing base surrounds a heat-generating electronic component at a center and allows the placement of a cooling module therein, and a rising corner column is disposed at each of four corners thereof and each corner column has a snap hole; the flexible frame is composed of two M-like retention brackets whose bottom sides are mounted with a retention hook respectively for the corresponding snap hole, a lever is pivotally disposed at a lower center location thereof and pertains to a metal rod whose one end is integrally bent to form a protruded portion. The production process requires no mold so as to simplify the production process and reduce the production cost.

Abstract: An intelligence carrier is disclosed, which is primarily comprised of at least a frame and at least a movable part. The frame is configured with at least a RFID reader and an antenna so that the movable part, being attached by a RFID tag, is able to communicate with the aforesaid RFID reader through the RFID tag, and then, as the RFID reader is able to communicate with a center control, the position of each movable part can be tracked in real time and the amount of the movable parts can be monitored.

Abstract: The invention relates to a directory proxy caching system that is constructed based on a predicate, i.e., a query from a client. Broadly stated, the predicate is formed by the query (request) issued by the client. Once the data is found in the directory, then the data is stored in a cache of a proxy server. The data is indexed in the proxy server by the predicate. The predicate is used to form an index by sorting the predicate into a normal form. Steps in sorting the predicate into the normal form include the following. Each symbol of the predicate is represented by a numerical representation, for example the ASCII value used to represent the symbol in ordinary text files. The predicate is expressed as a plurality of primitive predicates, and individual predicates of the plurality of primitive predicates are joined by logical connectors. The logical connectors, and each term in the primitive predicates are represented by numbers.

Abstract: A method for forming a certificate is provided. Generally, a first public key of a first encryption type is placed in the certificate. A second public key of a second encryption type is also placed in the certificate.

Abstract: The invention relates to a distributed directory service that is constructed based on a predicate, i.e., a query from a client. The predicate is formed by the query (request) issued by the client. The predicate is used as an index for retrieving data from a plurality of directory servers. Retrieving the data has the following steps. Each directory server is designated by a designation predicate giving a range of data values stored in the directory server. A client predicate indicates desired information. The client predicate is compared with the designation predicates to determine which directory servers may contain information requested by the client predicate. In the event that a particular designation predicate indicates that a portion of the desired information may be stored on a particular directory server, an inquiry is sent to the particular directory server for the desired information. The retrieved information is transferred to the client computer.
