Abstract: System and method for controlling the presentation of information, such as dynamically displayed text, includes a computer with a display device and one or more sets of electrode plates and capacitive field sensors arranged facing each other on a substantially flat and substantially stationary surface, such as a table top. The method includes forming capacitive fields between the electrodes and sensors by electrically charging the electrode plates. The sensors monitor for gestural movements made by a user's hands within the fields by detecting changes in voltage levels of the fields. In response to detected gestural movements, the computer adjusts the manner in which the information is presented in the display device, such as the display rate, information source, font size and contrast control.

The system includes an input device associated with a non-standard I/O device for obtaining communication transaction data and a client program for generating a communication transaction message in an extended open network protocol with the communication transaction data.

Abstract: A storage system including a queue corresponding to each priority level of command and an activation order control part. A command received from a host is accumulated in the queue corresponding to the specified priority. The activation order control part decides the number of activation object commands to be activated among accumulated commands, based on the priority corresponding to the queue. The activation order control part decides the activation order of the activation object commands, based on a activation object command number decided for each queue, so that the average value of logical response time of the activation object command may be shorter at the higher priority. The activation object command is activated in accordance with the decided activation order.

Abstract: The system according to the present invention for data transfer between microcomputer devices contains a standard protocol controller, a generally known ethernet controller, for example, as a coupling device instead of the known multipart RAM. Instead of a parallel data connection, the microcomputer devices are coupled to one another via a standardized, serial data connection, for example, ethernet. Using functions of ethernet switches already known, a number of microcomputer devices in the system may be increased.

Abstract: The present invention discloses a method of editing a multi-media playing schedule for a digital photo frame, a system and a computer readable storage medium thereof, which are characterized in that users can edit a multi-media playing schedule on the data processing apparatus when the digital photo frame is electrically connected to the data processing apparatus, and after editing of the multi-media playing schedule is finished, the multi-media playing schedule is transmitted to the digital photo frame and stored in the digital photo frame. Therefore, the problem of being unable to edit complicated multi-media playing schedules due to simple operation interface of digital photo frames can be solved.

Abstract: A device for data packet processing is disclosed. In one embodiment, the device includes a processor implemented on a chip, an on-chip internal segment memory accessible by the processor, an off-chip external segment memory and a data transfer channel between the internal segment memory and the external segment memory. The external segment memory comprises first and second memory segments wherein the first and second memory segments are different in size.

Abstract: Methods and systems for performing direct memory access (DMA) transfers are described. An invalidate queue (or other storage device) contains an entry associated with a DMA transfer in progress. If the invalidate queue detects an invalidation of a memory page associated with that entry, then it is marked invalid. If the entry is marked invalid during the DMA transfer, then that DMA transfer is aborted. This enables, among other things, DMA transfers to unpinned virtual memory.

Abstract: A method for data distribution, including distributing logical addresses among an initial set of devices so as provide balanced access, and transferring the data to the devices in accordance with the logical addresses. If a device is added to the initial set, forming an extended set, the logical addresses are redistributed among the extended set so as to cause some logical addresses to be transferred from the devices in the initial set to the additional device. There is substantially no transfer of the logical addresses among the initial set. If a surplus device is removed from the initial set, forming a depleted set, the logical addresses oldie surplus device are redistributed among the depleted set. There is substantially no transfer of the logical addresses among the depleted set. In both cases the balanced access is maintained.

Abstract: The present invention relates to an application of the Universal Serial Bus (USB) technology, and more particularly, to a USB apparatus with data storage and security token and control method therein. In an embodiment of the present invention, both mass storage and security token are implemented in a USB apparatus with a single controller. Thus, the host needs to enumerate the apparatus only once, and then may operate differentially in response to different commands. The mass storage is capable of swapping a mass of data, and has a file allocation table compatible with the system. The security token can be used for authenticating a person through digital certificates or biometric characteristics, maintaining the security of the computer and network applications.

Abstract: A method and mechanism for managing requests to a resource. A request queue receives requests from multiple requestors and maintains a status for each requestor indicating how many requests the requestor has permission to issue. Upon initialization, the request queue allots to each requestor a predetermined number of “hard” entries, and a predetermined number of “free” entries. Un-allotted entries are part of a free pool of entries. If a requestor has an available entry, the requestor may submit a request to the request queue. After receiving a request, the request queue may allot a free pool entry to the requestor if the free pool currently has entries available. Upon de-allocation of a queue entry, if the entry corresponds to a hard entry, then the hard entry is re-allotted to the same requestor. If the entry is a free entry, the entry is made available and a free pool counter is incremented.
