摘要： The present invention relates to a pneumatic servo valve, and more particularly, to a pneumatic servo valve, wherein displacement of a spool due to flow force of a fluid is prevented by firmly holding the spool just after position control for the spool is completed, thereby ensuring the stability of a valve system, and an encoder is employed as a spool position detecting means. The pneumatic servo valve comprises a hollow main body with a supply port, a discharge port and an exhaust port; a sleeve which is contained in a hollow portion of the main body and has slots communicating with the respective ports, and a chamber therein; a spool axially slidably installed within the chamber to control the flow of a fluid into the respective ports according to the position thereof; a torque motor installed at one side of the main body to control the position of the spool in response to electrical signals; and a spool position detecting means for compensating positional errors by receiving the fedback position of the spool. The pneumatic servo valve further comprises a spool holding means including a ball nut 60 which is engaged, via a ball, with a helical groove formed on a connection rod of the spool connected to the torque motor and rotates when the spool moves linearly, and an electronic brake for holding the ball nut not to rotate when the spool is stopped.

摘要： A mobile terminal executes a navigation function by receiving Transport Protocol Experts Group (TPEG) traffic information through a Digital Multimedia Broadcasting (DMB) network. This DMB-based mobile terminal receives and decodes TPEG data at a separate second processor different from a conventional first processor. Further, the DMB-based mobile terminal may execute a calculation of an optimum route at the second processor. The terminal and a related method reduce the processing load of the first processor, which causes a decrease in the response time to a user's navigation request and improves a user's convenience.

摘要： Disclosed are a hinge assembly and a mobile device having the hinge assembly. In the mobile device, a rotation portion 14 slides and rotates on a base portion 10, so as to be inclined to the base portion 10. For this reason, the rotation portion 14 is connected to the base portion by means of the hinge assembly 20 so as to slide and rotate on the base portion 10. The rotation portion 14 slides on the base portion by a predetermined distance, and then rotates to be inclined at a desired angle with respect to the base portion 10. The rotation portion 14 easily rotates with respect to the base portion of the mobile device, so that the status of the mobile device can be easily converted. Further, when the status of the mobile device is converted, the front, rear, left and right of a display screen is not changed. As a result, the mobile device should not have a structure of changing a display direction of the display screen. Further, there is an advantage in that an electric connection between the base portion and the rotation portion by means of a connection link mechanism can be stably achieved.

摘要： An embodiment of the invention provides an apparatus and method for varying a voltage controlled oscillator (VCO) sensitivity. A VCO has an oscillator portion coupled to a variable current supply. The variable current supply has one or more enabled variable current cells. The enable variable current cell input provides a control to change the VCO sensitivity. In an example, the oscillator portion has a ring oscillator. In an example, the variable current supply has at least two variable current cells that supply the control current. A binary control signal alters a quantity of variable current cells that supply the control current. Each successive variable current cell has an output current substantially equal to twice that of a prior variable current cell.

摘要： Provided is a method for setting a security channel between an OLT and at least one ONU in an EPON. In detail, a channel is generated by which the OLT makes a reciprocal security capability agreement with the ONU that wants to set a security channel in a discovery interval and then automatically registers the ONU with the security capability agreement. The security channel is set by which the OLT distributes an encryption key for the security with the ONU completed with the security capability agreement. A renewal point of the encryption key is shared by transmitting a message indicative of a time to change the encryption key between the OLT and the ONU both completed with the encryption key distribution.
