  • Patent number: 11134168
    Abstract: Systems and methods are provided though which a transaction, e.g., in a multi-tier, distributed application may be initiated from a portable or hand-held device, such as a smartphone. A computer system or systems, possibly remote from the device, may approve the transaction, complete it, or both, and the remote computer system or systems may cause a document to be printed, e.g., by a printer physically proximate to the device. Aspects of the invention are illustrated by embodiments in which a drug prescription may be created electronically using a hand-held device. In such an embodiment, the prescription may be transmitted to one or more remote computer systems, such as an application server, for processing. If specified, the remote computer systems may cause a prescription to be printed, e.g., at a printer near the prescriber's location. The prescriber may sign the printed prescription and give it to a patient or pharmacy.

  • Patent number: 11128590
    Abstract: Embodiments of the invention include systems and methods for transmitting messages related to certain information while maintaining the confidentiality of that information. A potential recipient may register one or more devices for receipt of such messages while specifying rules regarding when different messages may be delivered to the various devices. To keep sensitive information confidential, the messages may include only a link to such sensitive information, but exclude the sensitive information itself. An authorized recipient may then use the link to access the sensitive information via a password-protected Web site.

  • Patent number: 11036369
    Abstract: Computer systems and methods may display multi-dimensional data sets in a dynamically-generated ocular view, which may show the relationship between data points in the different dimensions. For example, such a data set may include in one dimension results of one or more laboratory tests and, in another dimension, body systems or functions that the respective tests may relate to. The ocular view may depict the relationships between the tests and the systems. By being generated dynamically, moreover, the ocular view may be able to present this information for arbitrary sets of test results, without a template having been generated in advance to specify the layout of some particular combination of results.

  • Patent number: 11028450
    Abstract: The present invention relates to methods for the diagnosis of bacterial vaginosis based on an analysis of a patient sample. For example, patient test samples are analyzed for the presence or absence of one or more lactobacilli and two or more pathogenic organisms. The presence or absence of one or more lactobacilli and two or more pathogenic organisms may be detected using PCR analysis of nucleic acid segments corresponding to each target organism. The quantity of the target organisms can then be used to determine a score which is indicative of a diagnosis of bacterial vaginosis.
