113 results about "Feedback loop" patented technology

A feedback loop (FBL), sometimes called a complaint feedback loop, is an inter-organizational form of feedback by which a mailbox provider (MP) forwards the complaints originating from their users to the sender's organizations. MPs can receive users' complaints by placing report spam buttons on their webmail pages, or in their email client, or via help desks. The message sender's organization, often an email service provider, has to come to an agreement with each MP from which they want to collect users' complaints.

Method, System, and Computer Program Product for Customer Linking and Identification Capability for Institutions

In an enterprise where a database maintains multiple accounts for one or more business customers, a method, system, and computer program product correctly links accounts which are associated with a single location of a common business. Further hierarchical linkages are established between accounts associated with multiple locations of the common business. The linkages are established via matching rules, the matching rules including provisions for optimizing the quality of the account data, integrating account-related data from external sources, and assigning quality-of-matching factors to different kinds of account data. Both internal and external account data are utilized to create an integrated view, or “business demographics”, of the business structure of the single common business shared by the linked, hierarchically-related accounts. Separate accounts of separate businesses which are nonetheless related accounts may be associated with each other. Feedback loops may be used to correct both erroneous data and the linking rules.

System for providing and managing a laminar flow of clean air

A system for providing and managing a laminar flow of filtered air for a clean room workspace has a blower for blowing air through a filter and over the work area. The velocity of air flowing through the filter is automatically controlled by a feedback loop wherein sensors enable the system to learn of a drop in flow, or even a flow rate that strays above a set point, and to then take action to change settings of the variable frequency drive which, in turn, vary the current to the motors causing a change in blower speed. The system's programmable logic control also provides for automatic recording and storing of data relating to the operating characteristics of the system, including the date and time that the operating characteristics were recorded. The recording may be done in a manner so as not to be editable by the system operator, which makes such record compliant with federal regulations.

Architecture for generating adaptive arbitrary waveforms

A test system having a feedback loop that facilitates adjusting an output test waveform to a DUT / CUT (Device Under Test / Circuit Under Test) on-the-fly according to changing DUT / CUT parameters. The system includes a tester having an arbitrary waveform generator (AWG) and a data acquisition system (DAS) that monitors the status of the DUT / CUT. The AWG and DAS connect to the DUT / CUT through a feedback loop where the AWG outputs the test waveform to the DUT / CUT, the DAS monitors the DUT / CUT parameters, and the DAS analyzes and communicates changes to the AWG to effect changes in the output waveform, when desired. The AWG builds the output waveform in small slices (or segments) that are assembled together through a process of selection and calibration. The feedback architecture facilitates a number of changes in the output waveform, including a change in the original order of the preassembled slices, and changes in the magnitude / shape of the output waveform.

Method and system for carrier recovery

A method and sytem for achieving carrier frequency synchronization in a high speed receiver. A feedback loop in a carrier recovery system is operated at a down-sampled rate until carrier lock is detected. The output of a phase accumulator, operating at the down-sampled rate, is then extrapolated to provide extrapolated outputs to provide outputs at the original symbol rate. Addresses for a look-up table are then generated from the combined phase accumulator outputs and extrapolated outputs, such that the frequency and phase compensation offsets provided to a phase derotator and slicer are at the original symbol rate. The total pipeline delay as seen by the carrier recovery system is thus reduced. This in turn allows for more efficient correction of residual carrier frequency errors present in a complex baseband signal.

Automated health model generation and refinement

The present invention extends to methods, systems, and computer program products for automatically generating and refining health models. Embodiments of the invention use machine learning tools to analyze historical telemetry data from a server deployment. The tools output fingerprints, for example, small groupings of specific metrics-plus-behavioral parameters, that uniquely identify and describe past problem events mined from the historical data. Embodiments automatically translate the fingerprints into health models that can be directly applied to monitoring the running system. Fully-automated feedback loops for identifying past problems and giving advance notice as those problems emerge in the future is facilitated without any operator intervention. In some embodiments, a single portion of expert knowledge, for example, Key Performance Indicator (KPI) data, initiates health model generation. Once initiated, the feedback loop can be fully automated to access further telemetry and refine health models based on the further telemetry.

DC offset correction using multiple configurable feedback loops

The present invention provides a DC offset correction system for a wireless communication device that removes a DC offset from a baseband receive signal during “training time” when the baseband receive signal should ideally have no DC content. In general, the DC offset correction system includes multiple configurable feedback loops that operate to remove or cancel the DC offset from the baseband receive signal. One or more of the multiple configurable feedback loops is activated for a period of time during operation when it is known that the received signal should ideally contain no DC content. This training time varies depending on the particular communication standard being used by the wireless communication device. For example, the training time may be during reception of the preamble and header of an IEEE 802.11 packet.
