Abstract:
Systems for providing dual resolution control of display panels are provided. A representative system incorporates two pairs of shift registers, each of the shift registers outputting a shifting signal; two pairs of logic gates; and a switching network coupled among the shifting registers and the logic gates. In a low resolution mode, the switching network causes the shift registers to output shifting signals, with corresponding pulses of the shifting signals of the shift registers of the first pair temporally overlapping with corresponding pulses of the shifting signals of the shift registers of the second pair; and wherein, responsive to the shifting signals, the logic gates output panel control signals, with corresponding pulses of the panel control signals of the logic gates of the first pair not temporally overlapping with corresponding pulses of the panel control signals of the logic gates of the second pair.
Abstract:
Methods and systems thereof for controlling access to resources are described. When a user attempts to access a resource via a remote interface such as a Web server, the request is initially evaluated by a source of policy definitions such as a policy server. This source returns a policy decision to the remote interface. The policy decision is stored in memory by the remote interface. The remote interface can then evaluate subsequent requests from the user for the resource using the stored policy decision instead of having to communicate again with the source for the policy decision. Enhancements to this approach are also described. Accordingly, policy definitions and decisions are more efficiently implemented.
Abstract:
Embodiments of the present invention provide a circle of trust on a network. The circle of trust is configured by exchanging credential of a first and a second affiliated entity. The credentials of the first affiliated entity is stored in a trusted partner list of the second affiliated entity. The credentials of the second affiliated entity is stored in a trusted partner list of the first affiliated entity. Thereafter, a circle of trust session may be provided when a client device initiates use of a resource on a relying party device by providing an authentication assertion reference. The identity of the issuing party of the authentication is determined as a function of the authentication assertion reference. The relying party sends an authentication query containing its credential to the issuing party. The issuing party determines if the relying party is a trusted entity based upon whether the relying party's credential is contained in the trusted partner list of the issuing party.
Abstract:
A computer-implemented method of extracting key phrases from a document is disclosed comprising the steps of accessing a repository comprising linked subjects, the repository comprising first and second data structures representing the relationship between said subjects using different representation criteria; pruning the first data structure by removing links between subjects based on a further relationship between said subjects in the second data structure; matching phrases in said document to subjects in the pruned first data structure; further pruning the pruned first data structure by removing unmatched subjects that are not linked to matched subjects; determining a ranking for each matched subject; and selecting key phrases using the determined subject rankings. A computer program for implementing the steps of this method when executed on a computer is also disclosed.
Abstract:
This invention involves with a low power IC (Integrated Circuit) with high energy efficiency. This invention describes a Buck converter that can track the minimum energy point of the load. It works by estimating input energy of every sensing period, taking advantage of energy consumption curve of IC in sub-threshold. Energy estimation is implemented with counting conducted pulses, while maintaining constant input energy of each pulse by regulating output voltage and ON time with digital control circuit. With digital control circuit, minimum energy point can be tracked with a lookup table stored inside. Most of this invention's control circuit is digital, with benefits of low power consumption and small chip area.

Abstract:
Provided is a modulation device which generates a phase modulation signal and an amplitude modulation signal and can correct an I/Q orthogonal shift and reduce degradation of the ON/OFF ratio. In the device, a phase shifter (174) controls voltage applied to a capacitor in accordance with a control signal outputted from a phase control unit (180) and adjusts the capacitance so as to shift the phase of a carrier generated by an oscillator (173). The phase control unit (180) estimates a phase shift of a phase shifter (174) in accordance with an output RF signal (S140) by using the phase shift estimation method. Furthermore, the phase control unit (180) performs tuning of the phase shifter (174) according to the estimated value of the phase shift of the phase shifter (174) so that a phase difference between carries of an I signal (S125) and a Q signal (S135) is 90 degrees.
Abstract:
The teachings of the present disclosure relate to a method for receiving “N” data streams (wherein “N” is a number greater than one) from “N” endpoints. Each of the data streams are received from a different respective endpoint. The method also includes decoding the “N” data streams by generating a decoding signal input comprising the “N” data streams and then iteratively repeating the following steps “N”−1 times: determine a most reliable stream; decode the most reliable stream using linear multiple-input and multiple-output (MIMO) decoding; output the decoded most reliable stream; estimate a signal estimate based on the most reliable stream and modulation information associated with the most reliable stream; and generate a residual signal that comprises the remaining data streams less the signal estimate. Upon the residual signal comprising two data streams, the method includes updating the decoding signal input to be the residual signal. Upon the residual signal comprising a single received stream, the method includes decoding the residual signal using a maximum likelihood decoder.

An architecture for allowing extensibility to policies. The architecture has a policy component program that is able to evaluate and enforce polices. The architecture also has plugin modules for allowing a user to customize the polices. The policy component program is able to present interfaces to the user for customizing the polices. The policy component program is further able to integrate customized polices into a framework of the policy component program in response to user input that is based on the interfaces presented to the user. The presented interfaces may be for defining subjects in the policy program, defining conditions in the policy program, defining referrals in the policy program, defining resource names in the policy program, and defining how conflicts will be resolved in the policy program. The interfaces may be compliant with the JAVA programming language.
