A total hemoglobin index system derives total hemoglobin (tHb) index value utilizing a depopulated emitter with an index set of LEDs. A patient fails a tHb index test if tHb measurements are trending down and/or tHb values fall below a predefined index threshold. If a patient fails the tHb index test, a high resolution sensor derives a specific tHb measurement utilizing a high resolution set of LEDs. The number of high resolution set LEDs is greater than the number of index set LEDs.

A privacy-preserving index system addresses the problem of providing a privacy-preserving search over distributed access-controlled content. Indexed documents can be readily reconstructed from inverted indexes used in the search. The privacy-preserving index system builds a centralized privacy-preserving index in conjunction with a distributed access-control enforcing search protocol. The privacy-preserving index utilizes a randomized algorithm for constructing a privacy-preserving index. The privacy-preserving index is strongly resilient to privacy breaches. The privacy-preserving index system allows content providers to maintain complete control in defining access groups and ensuring its compliance, and further allows system implementors to retain tunable knobs to balance privacy and efficiency concerns for their particular domains.

Embodiments of a method for managing entities include candidate selection by a transitive bucketing process where at least one attribute of an initial data record is used to determine a set of candidate data records corresponding to the initial data record. For each candidate data record thus determined, additional candidate data record(s) may be determined using attribute(s) not used in linking the candidate data record to the initial data record. This process may be repeated until no more candidate data records are returned. The initial data record and related candidates thus determined are then resolved into group entities, each having member records that match one another above a certain threshold. If no match is found, a group entity comprising a single data record may be created. These group entities are then reconciled with other entities in a master entity index system.
