Abstract: The techniques disclosed herein provide methods, devices, and systems to compensate the drive waveform to a slow-scan mirror in a laser beam scanning (LBS) display device. The slow-scan controller generates the drive waveform, which is combined with feedback and coupled to the input of a notch filter in the control loop. Ripple in the slow-scan mirror trajectory, which occurs as a consequence of mismatches between the notch frequency of the notch filter and the resonance of the slow-scan mirror, is effectively suppressed in real time by an adaptive notch compensator. Consequently, the described compensation scheme allows for relaxed notch filter design criteria with high tolerance and mitigation of ripple is achieved at reduced cost. The parameters, logic and blocks of the adaptive notch compensator scheme may be time-domain or frequency domain solutions that are implemented, in hardware, software or combinations thereof.

Abstract: An advertiser budget is retrieved from a data store. A set of traffic sources associated with the advertiser budget are identified. An allocated budget for the set of traffic sources is generated by allocating at least part of the advertiser budget to the set of traffic sources. At least one advertisement is delivered via a traffic source of the set of traffic sources based at least in part on the allocated budget.

Abstract: Disclosed is a system for performing online data queries. The system for performing online data queries is a distributed computer system with a plurality of server nodes each filly redundant and capable of processing a user query request. Each server node includes a data query cache and other caches that may be used in performing data queries. The data query, as well as request allocation, is performed in accordance with an adaptive partitioning technique with a bias towards an initial partitioning scheme. Generic objects are created and used to represent business listings upon which the user may perform queries. Various data processing and integration techniques are included which enhance data queries. An update technique is used for synchronizing data updates as needed in updating the plurality of server nodes. A multimedia data transfer technique is used to transfer non-text or multi-media data between various components of the online query tool.
