摘要:
An optically-powered integrated microstructure pressure sensing system for sensing pressure within a cavity. The pressure sensing system comprises a pressure sensor having an optical resonant structure subject to the pressure within the cavity and having physical properties changing due to changing pressures within the cavity. A substrate supports the optical resonant structure. An input optical pathway evanescently couples light into the optical resonant structure. An output optical pathway collects light from the optical resonance structure. A light source delivers a known light input into the input optical pathway whereby the known light input is evanescently coupled into the optical resonant structure by the input optical pathway and a portion of such light is collected from the optical resonant structure by the output optical pathway. A light detector receives the portion of the light collected from the optical resonant structure, and generates a light signal indicative of such portion of the light collected from the optical resonant structure. A temperature compensation sensor generates a temperature signal indicative of the temperature near the optical resonant structure. A spectrum detection device receives the light signal and temperature signal. The spectrum detection device analyzing the light signal and the temperature signal with a detection algorithm to generating a pressure signal indicative of the pressure within the cavity.

摘要:
A system and method for detecting the optical spectrum of an optical input signal. The system includes a tunable optical filter having a microresonator that is tunable across a plurality of states and a processor. The input signal is coupled into the microresonator, which is continuously tuned across a spectral range that is narrow relative to the targeted detection range. Signal information such as center wavelength, power distribution, and power strength are extracted from the measured output intensities resulting from the interaction of the unknown input signal with the tunable resonator at various tuned states. The processor includes a transfer function database with the resonant spectra of the tunable optical filter at predefined states. The processor applies an iterative non-linear deconvolution algorithm, and preferably an accelerated Richardson-Lucy algorithm, to calculate the spectrum of the input signal using the transfer function information and the intensity measurements.
摘要:
A system, method and apparatus for enabling individuals to determine their sharing, privacy, and data access preferences and conditions for disclosure of bioinformatic data, including whole genome sequence data over a network. In combination with a privacy preferences repository and policy repository for expressing legal and institutional criteria for accessing such information, a private access bureau enables such privacy requirements to be addressed while simultaneously enabling broad sharing of such data by and with properly authorized parties or applications. Through the use of various forms of metadata, encryption, and globally unique IDs that accompany such data elements, discrete segments of said data can be queried; and where permissible discovered, accessed, analyzed, viewed, linked with other health data and contact details, used, and/or exported based on pertinent privacy laws, institutional policies, and the individual's preferences that are associated with, and dynamically controlled through, an intuitive user interface.
摘要:
A computer implemented system and method is provided for imposing access controls on selective portions of electronic documents by defining data attributes as conditions for access to particular information in a document. Commands from a redactor identify at least one portion of an electronic document to be subject to access control. A set of selectable access control directives defining conditions for accessing the identified portions is presented to the redactor. Access control is imposed on the identified portions in accordance with the defined conditions in response to receiving the selective access control directives.

A system and method for managing private records and other confidential information is provided, including a patient interface that allows patients to configure privileges for various parties to access various private records or portions thereof. A database can be accessed via a privacy engine, which respects the configured privileges and allows searching for private records. A plurality of user interfaces is provided to allow records managers, patients, and interested parties to access selected private information. A clinical trials interface allows limited access to a private records database for interested parties to identify germane clinical trials and research studies. A recruitment interface allows conductors of research studies to access private records to locate appropriate research subjects.
摘要:
A system for document retrieval in a network environment is provided where documents are stored with corresponding privacy codes. A query server computer is in communication with the network and is programmed to generate a privacy index of all documents available on the network indexed by their corresponding privacy codes. The privacy codes define document access permissions that are securely associated with the documents and are assigned by document custodians. A search engine in communication with the network is configured to receive a query from a requester and generate a list of documents from the privacy index which match search parameters of the query and privacy codes of the requester.
摘要:
The present invention provides a device and method for facilitating the placement of dental implants by use of an implant placement locator and a sequentially sized drill orientation tube series. The implant placement locator disclosed herein comprises a visible radiolucent moldable grid, a set of radiopaque markers located at known intervals within the moldable grid, and a plastic sheeting encasing the visible radiolucent moldable grid and the radiopaque markers. The method of the present invention comprises obtaining a radiograph of a patient's mouth with the implant placement locator overlaying the patient's dental ridge and then transferring reference points as indicated by the location of the radiopaque markers relative to existing teeth and other oral structures to a dental stone model. In a preferred embodiment, drill bits are directed in the desired trajectory into the patient's available lower or upper jaw bone by use of drill orientation tubes in combination with the implant placement locator. A sequentially sized set of spacers is provided having sequentially sized inside diameters to direct varying diameter drills. Drill guide parallelism is thus provided by the invention.
