Abstract: A method and apparatus for providing adaptive bearer configuration for MBMS delivery is disclosed. A first aspect of the present disclosure is a method of operating a wireless infrastructure entity (103) wherein a plurality of common radio resources (303) are allocated for receiving combined responses from a plurality of mobile stations (109). A request message, similar to a request for counting, is broadcast to all mobile stations (109) within a coverage area (105) and may indicate a range, for example a signal-to-noise-and-interference ratio range. Mobile stations (109) responding to the request, use specific resources (303) corresponding to respective range values. The infrastructure (103) may use the received information to determine a modulation and coding scheme for PTM broadcast. The total number of responses to the request message may be limited by providing a probability factor within the request message.

Abstract: A method and method and apparatus for data re-arrangement includes the steps of receiving output pixel coordinates (X, Y) and obtaining an input pixel offset value (?S, ?T), wherein the output pixel coordinate represents a location for a two dimensional matrix. The input pixel offset value is obtained in reference to initial input pixel coordinates (S, T) which may be received with the output pixel coordinates or calculated based on the input and/or output pixel coordinates. The input pixel offset value may be any type of representation that provides for a delta value, for example, (?S, ?T) may represent a shift representation for the offset within a matrix array. The method and apparatus for data re-arrangement further includes retrieving an input pixel based on the initial input pixel coordinates and the offset value.

Abstract: A method of integrating a personal computing system and apparatus thereof include processing that begins by integrating a central processing unit with a North bridge on a single substrate such that the central processing unit is directly coupled to the North bridge via an internal bus. The processing then continues by providing memory access requests from the central processing unit to the North bridge at a rate of the central processing unit. The processing continues by having the North bridge buffer the memory access request and subsequently process the memory access requests at a rate of the memory. The method may be expanded by integrating a South bridge onto the same substrate as well as integrating system memory onto the same substrate.

The transmitter also includes logic configured to determine values of the bits in the control character and construct a corresponding plurality of rebalancing control characters based on the determination of the values of the plurality of bits in the control character to have bit values selected such that the combination of the control character and rebalancing control character is DC balanced. As such, the transmitter provides DC balance correction to non-DC balanced control characters in such a way as to allow DVI and HDMI to operate properly on an AC-coupled connection.

Abstract: The present invention provides a method and apparatus for data compression that includes representing each sub-pixel of each pixel with a pointer corresponding to an attribute of the sub-pixel, the attribute being a floating point binary number. An overall attribute of each pixel is then determined. The determining of the overall attribute of each tile may include any one of assigning the attribute of the sub-pixels to the overall attribute of the pixel when the sub-pixels are represented by an identical pointer, and resolving the overall attribute of the tile by the attributes of the sub-pixels when the sub-pixels are represented by non-identical pointers of the pixel.

Abstract: A method and apparatus provides user authentication by communicating primary authentication information, such as user identification data and/or password data to an authentication unit via a primary channel such as over the Internet. An authentication code is generated by the authentication unit on a per session basis and is sent to a destination unit via a first secondary channel during the session. The destination unit then retransmits the authentication code, on a second secondary channel, to the first unit in a way that is transparent to a user of the first unit. The first device then send the received re-transmitted authentication code back to the authentication unit via the primary channel during the session.

Abstract: A circuit includes a clock generator for providing a clock signal to a synchronously operated digital circuit and a control signal generator for providing a control signal to the synchronously operated digital circuit. The control signal generator is interconnected to the clock generator to suppress the clock signal for a defined duration as a control signal is provided. The defined duration allows the control signal to settle to allow said synchronously operated digital circuit to unambiguously sample said control signal. The control signal generator may place the synchronous digital circuit in a lower power consumption state.

Abstract: A series of pumps for precise metering of ink to all zones of a web press. One set of the ink pumps is operated by a set of motors, one motor for every two zones. The motors are reversible, preferably with a toothed belt driving each pump. The other units include one motor for each pump, with the motor driving a shaft which drives a link arm, the link arm driving a pivot shaft with a variable stroke, ranging from zero to a full output. The link arms are driven individually or as a group, and each has its own stroke. In one case, the pivot shafts are operated by link arms which can be in or out of phase with each other. In another case, an eccentric on the drive shaft can be adjusted to produce a variable stroke of the link arms and the pivot shafts.

Abstract: Active sessions and dialogs may be moved between connections and P-CSCFs. For example, in some embodiments either new bindings may be created with a different connection for a Public User ID or the UE may re-register one or more specific bindings for a Public User ID from one connection to another. The capabilities improve service continuity when handing over between IP-CANs. FIG. 13 illustrates exemplary messaging for moving bindings to a new connection for a Private User ID between UE (1305) and P-CSCF (1307) when the UE (1305) is in a visited IP-CAN, that is, visited network (1303). The UE (1305) invokes the unprotected global seamless re-registration of the embodiments via an unprotected initial registration procedure wherein the UE (1305) includes a “seamless-ims” parameter in the Require and Proxy-Require headers of the REGISTER request (1313). The S-CSCF (1311) provides the capability to subsequently re-register bindings over new or existing connections.
