    Abstract: The present invention provides for employing SQL to introduce blockchain technologies into a relational database, and thereby leverage the inherent tamper-resistant properties of blockchain, without the need to completely rewrite existing or legacy relational database software. The invention creates a relational database inside of a blockchain and uses a conventional SQL interface for standard database operations. This reduces the burden of introducing blockchain technologies, while providing the benefits of the intrinsic security and verification features of blockchain technology. The invention provides a rich historical record of every transaction thereby greatly reducing, if not eliminating, the relational database's susceptibility to tampering. This allows for temporal queries on arbitrary records within the database and the generation of reports and audits for any point in the history of the database.

    Abstract: Check valves are disclosed, including check valve included in an aspirator, that includes a housing defining an internal cavity having a first port and a second port both in fluid communication therewith, and a sealing member within the cavity. The sealing member is translatable between a closed position against a first seat within the internal cavity of the housing and an open position against a second seat within the internal cavity of the housing.

    Abstract: Pressure piston actuators and systems for control of wastegate in a turbocharger pressure that include the pressure piston actuators are disclosed. The pressure piston actuator includes a housing defining a chamber and a pathway leading to the chamber, a piston disposed within the chamber, a rod connected to the piston by a ball-and-socket joint, and a spring disposed in the chamber to bias the piston, and hence the rod, into a retracted position. Then, when fluid is introduced into the chamber, the fluid applies pressure to the piston. Once the pressure overcomes the bias of the spring, the piston, and hence the rod, moves into an extended position. For the system, the pressure piston actuator has the connector on the end of the rod opposite the ball-and-socket joint connected to the valve portion of a wastegate of a turbocharger.

    Abstract: Systems and methods are provided for facilitating management of health care in medical facilities such as hospitals, clinics, emergency rooms, etc., for example by monitoring and assessing the quality of patient care. Data is collected and operated on relating to medical conditions, treatment, cost, care, events, outcomes and results of treatments, and data representing the collective experience of similar patients is mined to discover opportunities to improve the quality of health care. Statistical and comparative data and reports including such and other information indicate a quality of care and provide epidemiologically cogent information. Quality of care may be considered as achieving desired or expected norms of performance, including success, in a timely fashion, and can be judged not just by what functionally happens during a patient instigated encounter, but also by long term outcomes evidenced by the patient's passage through the health care delivery system.

    Abstract: Apparatus and methods are disclosed for viewing low-birefringence structures within samples directly, with the eye, in real-time. The sample is placed between an entrance polarizer and analyzer polarizer, the transmission state of one of which is changed dynamically to create a modulated view of the scene; against this background, birefringent structures are visible because of their different appearance when modulated. Modulation rates of 4 or more states per second; use of 4 or more states, or even a continuum of states, which lie substantially on a latitude line on the Poincare sphere; and orientation of the polarization components to produce a uniform background; produce a clear view that does not produce operator fatigue. Broad-band wavelength operation spanning 50 nm or more, or the whole visible range, is achieved, and it is compatible with integration into other microscopy modes such as Hoffman relief contrast.
