Abstract: The present invention controls a proportional control valve controlling the maximum flow of the flow pump to perform controlling the maximum flow of the hydraulic oil pump after checking whether the pump joint control is normal, receiving a flow value of the flow pump controlled by the proportional control valve, checking an error when the flow value received during a control of the maximum flow has an error, and assigning a weight value to the checked error to compensate for the flow value. Therefore, the present invention may decrease a number of an engine revolution speed and lower a driving fuel consumption and reduce a driving noise.

Abstract: A method and an apparatus for providing a location based service in a wireless communication system are provided. A method of a Base Station (BS) for a Location Based Service (LBS) in a wireless communication system includes allocating identifiers to a plurality of transmission devices in a service coverage area of the BS, generating a Reference Signal (RS) including the identifier of the corresponding transmission device and an identifier of the BS with respect to each of the transmission devices, and transmitting the RS generated for each of the transmission devices, to a Mobile Station (MS) via the corresponding transmission device.

Abstract: A method and apparatus for transmitting/receiving a reference signal for positioning in a wireless communication system are provided. In the method, a BS locates a PA preamble in a second frame among frames constituting each of multiple superframes, locates a SA preamble in first symbols of first and third frames among the frames constituting each of the multiple superframes, determines multiple consecutive first superframes belonging to an LBS zone from among the multiple superframes, includes a reference signal for LBS in a first symbol of a first subframe of a last frame among frames constituting each of the first superframes, includes data in a first symbol of a first subframe of a last frame among frames constituting each of second superframes that correspond to the multiple superframes excluding the first superframes when the data is to be transmitted, and communicates with an MS by using the first and second superframes.

Abstract: A method, an Advanced Base Station (ABS) and an Advanced Mobile Station (AMS) for transmitting Location Based Service (LBS) resource allocation information by an ABS in a mobile communication system are provided. The ABS transmits LBS resource allocation information including LBS zone configuration information representing an LBS zone transmission period. The LBS zone configuration information includes at least one of first information indicating that LBS zone transmission is switched off, second information indicating that the LBS zone transmission period corresponds to a first number of super frames, third information indicating that the LBS zone transmission period corresponds to a second number of super frames, and fourth information indicating that the LBS zone transmission period corresponds to a third number of super frames.

Abstract: An apparatus and a method for detecting a femto Base Station (BS) of a Mobile Station (MS) in a wireless communication system including a macro BS and a femto BS are provided. The method includes receiving a request, from the macro BS, to monitor an UpLink (UL) signal of an MS permissible by the femto BS to access, and monitoring the UL signal of the MS permissible to access.

Abstract: A method for fabricating leadless packages with mold locking characteristics is disclosed. A provided leadless leadframe has a plurality of units in a matrix, each unit includes an improved die pad with a plurality of indentations, such as semi-vias in the sidewall thereof and a plurality of leads around the die pad. After chip attachment and electrical connection, a plurality of package bodies for semiconductor packages are individually formed on the corresponding units and covered the indentations in order to enhance the horizontal mold locking capability of the die pad. Using punching, connecting bars of the leadless leadframe are removed to isolate the leadless packages.

Abstract: A process for manufacturing sawing type leadless semiconductor packages includes a post mold-curing step, which is performed after an encapsulant is formed and after connecting bars of a leadframe are removed. The connecting bars are formed between a plurality of package units of the leadframe to connect a plurality of leads in the package units. After die attachment and electrical connection, the encapsulant is formed over the package units and the connecting bars to encapsulate the chips. The connecting bars are removed prior to the post mold-curing step. Therefore the encapsulant can be cured without deformation or warpage, thereby facilitating the sequent processes.

Abstract: A leadless leadframe with an improved die pad for mold locking includes a die pad and a plurality of leads. The leads are arranged around the die pad. A plurality of indentations, such as side semi-vias, are formed on the sidewall of the die pad for filling a package body of the semiconductor package so as to enhance the horizontal mold locking capability of the die pad.
