A method and device for accessing a broad data field having a fine resolution. The user selects a scale which can be varied. The scale controls a range within the data field. By moving the range to encompass different portions of the data field, the user can scan that portion of the data field. The present invention allows the user to simultaneously select the scale while moving the range over different portions of the data field. Thus, the user can "zoom in" and "zoom out" of different portions of the data field. In one embodiment of the present invention, a particular piece of data within the broad data field can be accessed. First, the scale is selectively varied, thereby controlling a range within the data field. Then, the range is moved to encompass portions of the data field in which the piece of data resides. Next, the scale is successively decreased while, simultaneously, points successively closer to the location are kept with the range. The scale is decreased (i.e., increasing the range's resolution) and the range is moved in this manner until the piece of data is actually accessed.

The present invention relates to compositions of aqueous compositions comprising relative permeability modifier (RPM) macromolecules and one or more formation damage control additives, for use in treating hydrocarbon-producing wells, formations, and equipment, as well as methods for the use of such compositions. Such compositions, comprising the RPM macromolecule and the one or more formation damage control additive, such as a scale control agent, can result in the formation of a composition wherein the components exhibit a “synergistic” effect, whereby the ability of the formation damage control additive to prevent formation damage is enhanced relative to the use of the same additive separately.

A server array controller that includes a Data Flow Segment (DFS) and at least one Control Segment (CS). The DFS includes the hardware-optimized portion of the controller, while the CS includes the software-optimized portions. The DFS performs most of the repetitive chores including statistics gathering and per-packet policy enforcement (e.g. packet switching). The DFS also performs tasks such as that of a router, a switch, or a routing switch. The CS determines the translation to be performed on each flow of packets, and thus performs high-level control functions and per-flow policy enforcement. Network address translation (NAT) is performed by the combined operation of the CS and DFS. The CS and DFS may be incorporated into one or more separate blocks. The CS and DFS are independently scalable. Additionally, the functionality of either the DFS or the CS may be separately implemented in software and/or hardware.

A ring-type remote control device, a scaling control method and a tap control method are provided. The ring-type remote control device includes a processing unit, a wireless communication module, a motion sensor module and a proximity sensor. The motion sensor module detects position information of the ring-type remote control device. The proximity sensor detects a distance variation between the first and second fingers of a user. When the processing unit determines the distance decreases according to the position information and the distance information, a reduced signal is generated and transferred to the wireless communication module. When the processing unit determines the distance increases, an enlarged signal is generated and transferred to the wireless communication module. The wireless communication module transmits a command corresponding to the reduced signal or the enlarged signal to an interactive receiving device, so as to generate an interactive operation.

A karaoke apparatus and the method thereof are provided, which guarantees the pitch of the karaoke music conforms to the pitch of the user. The apparatus comprises an audio input unit, a scale detector, a memory unit, a processor and a scale control unit. The audio input unit receives a test sound. The scale detector analyzes at least one test step of the test sound. The memory unit stores a plurality of standard steps. The processor finds out the highest step among the test steps, compares the highest step with the standard steps, and obtains a target step from the comparison; wherein, the target step is the standard step closest to the highest step. Finally, the scale control unit adjusts the pitch of the karaoke music so that the pitch is lower than that of the target step.

A method for registering patterns on a web to provide independent scale control in both the lateral and longitudinal directions is provided. The method comprises routing the web over a first roller; routing the web over a second roller and stabilizing the web; applying a pattern to the web using process hardware; measuring registration of the pattern and providing an error signal; controlling lateral position error using the error signal; controlling longitudinal position error using the error signal; controlling lateral scale error using the error signal; and controlling longitudinal scale error using the error signal. The method provides independent scale control in both the lateral and longitudinal directions. Independent scale control avoids non-linear distortions otherwise imposed by attempting to accomplish both corrections by stretching the web in both directions.
