  • Publication number: 20190340368
    Abstract: A first raw value of a first field from the first set of fields is encrypted to generate a first token using a symmetric key encryption mechanism based on a first cryptographic key associated with a first time window after which the first cryptographic key is no longer valid for tokenization of raw fields of raw log records. After the first time window has elapsed, a second raw value of a second field from the second set of fields is encrypted to generate a second token using the symmetric key encryption mechanism based on a second cryptographic key that is different from the first cryptographic key. The second cryptographic key is associated with a third time window that occurs after the first time window and after which the second cryptographic key is no longer valid for tokenization of raw fields of raw log records.

  • Publication number: 20190342088
    Abstract: A method and apparatus for tokenization of user-traceable data are described. User traceable data is data that is not directly personal data but can be traced back to the identity or an activity of the user. A first raw value is encrypted into a first token using a symmetric key encryption mechanism based on a combination of a second raw value including personal data of a user and a second token resulting from the tokenization of the second raw value where the first token is an anonymized representation of the first raw value.

  • Patent number: 10235476
    Abstract: Some embodiments of the present invention include a method for identifying match candidates in a database object and may include generating, by a database system, a match key associated with a lookup field of a database object. The method may further include activating, by the database system, a matching rule associated with the match key, and receiving, by the database system, a request to search for duplicate candidates in the database object. The request may include an input entity. The duplicate candidates in the database object may be identified by using the input entity and the matching rule.

  • Patent number: 9740743
    Abstract: Matching objects using keys based on match rules is described. A system generates a match rule key based on a match rule, wherein the match rule specifies whether two objects match. The system creates candidate keys by applying the match rule key to data objects. The system creates a probe key by applying the match rule key to a probe object. The system determines whether the probe key matches a candidate key. The system determines whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object if the probe key matches the candidate key corresponding to the candidate object. The system identifies the probe object and the candidate object as matching based on the match rule if the probe object matches the candidate object.

  • Publication number: 20110264668
    Abstract: Secondary indexing mechanisms are disclosed. A first index is created in a database environment. The index has a scope defined by a set of files that meet a pre-selected criteria. Second index generation is initiated. Te second index has the same scope as the first index. A first time period between initiation of the generation of the second index and completion of the second index is determined. The second index is swapped with the first index in an atomic swap operation. The indices may be generated for a multitenant database environment. Catch up indexing may be performed for the secondary index.

  • Publication number: 20100311116
    Abstract: The present invention provides a novel method for the fast generation of high expression stable cell lines for the production of recombinant proteins with high efficacy of stable integration while using low selective pressure for only a short period of time. The method uses transiently expressed piggybac transposase to mediate stable integration of a transgene of interest flanked by the PB transposon termini.

  • Publication number: 20080145893
    Abstract: Recombinant proteins are of great commercial interest. Yet, most current production methods in mammalian cells involve the time- and labor-consuming step of creating stable cell lines. Production methods based on transient gene expression are advantageous in terms of speed and versatility, yet, thus far, those methods have not shown the specific productivity, batch yield and volumetric yield to be an economic alternative to stable cell lines. The inventors improved on the methodology of transient transfection and achieved commercially relevant yields in terms of specific productivity (exceeding 35 pg per cell per day), batch yield (exceeding 700 mg/l) and volumetric yield.

  • Publication number: 20060219217
    Abstract: In one presently preferred embodiment a stratified scavenging carburetor has a scavenging air passage with an air control valve and a fuel and air mixing passage with a throttle control valve, and a lost motion coupling associated with the valves to delay opening of the closed air valve until the throttle valve has partially opened from its idle position to an off idle position and preferably thereafter to open the air valve in phased relationship with the throttle valve so that the valves become wide open at substantially the same time. Preferably the coupling has reels associated with the valve and connected by a flexible cord.

  • Publication number: 20060025702
    Abstract: An evoked potential monitoring system including a control unit having stimulator circuitry and a probe assembly coupled to the control unit. The probe assembly includes a stimulus probe and a stimulator handpiece selectively coupled to the stimulus probe. The handpiece includes a handle, control circuitry, and a switch. The control circuitry is electrically coupled to the stimulator circuitry. The switch is electrically coupled to the control circuitry and extends to an exterior portion of the handle. In this regard, movement of the switch remotely controls the stimulator circuitry to continuously increment or decrement a stimulation energy level delivered to the stimulus probe over a series of discrete, incremental steps.

  • Publication number: 20050085743
    Abstract: An intraoperative neural monitoring system includes a power source and a simulator powered by the power source to deliver a cycle of electrical stimulation to a patient as a first group of positive or negative phase pulses automatically followed by a second group of pulses of opposite phase or polarity to the pulses of the first group. An activation performed to initiate delivery of the first group of pulses is effective to deliver the entire cycle of stimulation. A method of intraoperative neural monitoring involves activating a simulator to deliver a biphasic cycle of electrical stimulation to a patient during an operative procedure, delivering the entire cycle of electrical stimulation to the patient in response to the activating step and detecting EMG activity in the patient.
