Systems and methods for managing operation of multiple tape drives in a way so that incoming data is spread or distributed across the multiple tape drives and which may be implemented in one example to continuously accept for recording without interruption from one or more data sources, for example, so that the date is distributed across the multiple tape drives in real time and without interruption as it becomes available from one or more given data sources. Two or more tape drives may be further be managed in a manner such that the multiple drives appear to be a single drive when writing data to, or reading data from, the multiple tape drives.

Provided is a transversal filter, in which delayers and multipliers are connected in series, includes: a first multiplier for multiplying a first tap coefficient set by a tap coefficient register module and an input signal to output a result of multiplication; a first delayer for delaying the value output from the first multiplier by a predetermined time to output the delayed value; a second multiplier for multiplying a second tap coefficient set by the tap coefficient register module and an input signal to output a result of multiplication; a first adder for adding the value output from the delayer situated upstream to the value output from the second multiplier to output a result of addition; a second delayer for delaying the value output from the first adder by a predetermined time to output the delayed value; and a selector for selecting one of the input signal, the value output from the first delayer, and the value output from the second delayer to output the selected one.

The invention relates to a method of, and system for, linear speed control for an electric motor, in which a digital to analog converter means is used for converting an 8-bit digital signal to an analog voltage for setting voltage across a motor, a digital state machine means is used for converting the duty cycle of an input signal for output to the digital to analog converter means, and a closed loop feedback loop means is used for monitoring and setting the voltage across the motor. An over-current sense circuit can be used for monitoring the current across the electric motor. An over / under voltage sense circuit can be used for monitoring voltage of the electric motor. The resulting 8-bit digital control signal is converted to an analog voltage for the electric motor. Such methods and systems find particular use in automotive applications.

A control message processing method and a control message processing apparatus using the method on a wireless mesh network are provided where a neighbor solicitation (NS) information is generated by extracting a part or an entire NS message, the NS message having been generated to request a medium access control (MAC) address of a destination node. A modified route request (RREQ) message, including the NS information, is generated to request the MAC address of the destination node and a routing path to the destination node, and is broadcasted.

The invention discloses a request handling method of a 3D MLC flash device. The method comprises the following steps: performing a read request by a read request fir mode; performing a write request while a wafer is idle; ensuring that the working mode of the related wafer is consistent with the working mode of the related block during performing the read / write request; performing trash recoveryrequest while the wafer is idle; selecting the block with the least active pages in the block under an SLC mode as the block to be recovered in case of insufficient current capacity of the device; selecting an idle block of the SLC mode as a target block in case of jam in current array of the device; setting the wiped working mode of the block to be recovered as the MLC mode in case of insufficient current capacity of the device; and circularly setting the working mode of the next wafer as the SLC mode in case that the total wiping quantity of all wafers is certainly increased. According to the method, the new properties of a 3D MLC flash chip can be fully utilized, so that the delay time in trash recovery can be decreased, and the service life of the flash device is prolonged.

A ranging method in a mobile station of a femto system is disclosed. According to the present invention, a femto base station enables non-synchronized ranging channel (NS-RCH) information to be carried on S-SFH SP1. A mobile station receives S-SFH and then determines whether a base station is a femto base station. If the base station is the femto base station, the mobile station is able to perform a periodic ranging using the NS-RCH information within the S-SFH as well as an initial / handover ranging.

Certain embodiments relate to a method for use in a wireless device. The method includes allocating uplink power between parallel transmissions during subframes that the wireless device has scheduled on two or more uplink physical channels. The parallel transmissions include one or more short transmission time interval sTTI transmissions, and the UL power is allocated according to at least one prioritization rule. According to one of said prioritization rules, sTTI transmissions comprising control information are prioritized over sTTI transmissions comprising data but without any control information. According to another of the prioritization rules, transmissions with shorter transmission time intervals are prioritized over transmissions with longer transmission time intervals.

A content joint editing method according to an embodiment of the inventive concept may preserve the real-time property of update of edits as much as possible even if the number of editors increases when multiple editors simultaneously edit content. A content editing method can share and edit various contents without calling a separate external application in an online collaboration service. A content sharing method can manage each user's access rights to a content in individual content units in collaboration service that displays a plurality of contents at the same time in the collaboration space for sharing contents among multiple users.
