  • Publication number: 20240113974
    Abstract: Mobile management method, system and client. Method includes receiving a DNS query for a host name from an application on client; retrieving reputation data associated with host name from a local cache on client; and determining a policy based on host name and the reputation data. Based on determined policy for the host name, blocking attempted network flows to a host corresponding to host name to produce blocked attempted network flows. Method also includes sending attempted network flow metadata related to the blocked attempted network flows to a collector on client; transmitting the attempted network flow metadata from the collector to a VPN server pool via a VPN tunnel; and producing an anomaly report from the transmitted attempted network flow metadata. The anomaly report includes at least one of anomalies, cohorts, trends, location boundaries, detected network security issues, detected compromised clients and/or optimized network usage.

  • Patent number: 11426089
    Abstract: A device for detecting acute coronary syndrome (ACS) events, arrythmias, heart rate abnormalities, medication problems such as non-compliance or ineffective amount or type of medication, and demand/supply related cardiac ischemia is disclosed. The device may have both implanted and external components and can communicate with other user devices such as smartphones and smartwatches for monitoring and alerting in response to detected medically relevant events or states of a patient. The processor is configured to provide event detection based upon various criteria including what is found to be statistically abnormal for a patient or what has been defined by a doctor to be abnormal. A patient's cardiovascular condition can be tracked over time using histogram, trend, and summary information related to heart rate and/or cardiac features such as those measured from the S-T segment of heartbeats.

  • Patent number: 9486153
    Abstract: Disclosed is a system having an implanted component and external component which are configured to provide a test of wireless communication in order to assess the success or failure of such communication and to store attributes related to such test in a memory log. To provide the communication test the implantable and external components can attempt wireless communication according to communication test parameters which relate to number of times to retry communication, duration of sending communication test signals, durations of waiting for communication test signals and the schedule of the communication tests. The schedule of tests may be period or may change over time in order to become more or less frequency according to a programmable schedule that may also decrease if the communication tests are successful and indicate patient compliance in keeping the external components close by.

  • Patent number: 8805498
    Abstract: A device for detecting cardiac ischemia is disclosed. The device includes a processor that is configured to distinguish between two different heart beats types such as ventricularly paced beats and supraventricular beats. The processor collects separate reference data for each beat type indicative of the normal values of a cardiac feature associated with these beat types. The processor performs an ischemia test by separately comparing present values of the cardiac feature for each beat type with the reference values for the corresponding beat type.

  • Patent number: 8452404
    Abstract: A device for detecting cardiac ischemia is disclosed. The device includes a processor that is configured to operate in three different modes according to relative frequency of different beat types. If beats of a first beat type, such as ventricularly paced beats, are predominant, the processor ignores other beat types and performs ischemia detection only on ventricularly paced beats. Conversely, if beats of a second beat type, such as sinus or atrially paced beats, are predominant, the processor ignores ventricularly paced beats and performs ischemia detection only on sinus or atrially paced beats. If there is a mixture of beat types such that neither predominates, the processor performs ischemia detection on both beat types.

  • Patent number: 8170653
    Abstract: A system for the detection of cardiac events occurring in a human patient is provided. At least two electrodes are included in the system for obtaining an electrical signal from a patient's heart. An electrical signal processor is electrically coupled to the electrodes for processing the electrical signal and a patient alarm means is further provided and electrically coupled to the electrical signal processor. The electrical signal is acquired in the form of electrogram segments, which are categorized according to heart rate, ST segment shift and type heart rhythm (normal or abnormal). Baseline electrogram segments are tracked over time.

  • Patent number: 6490603
    Abstract: Structured-format documents are produced in a process in which a file in a particular word processing format (input A) or in any other format (Input B) are converted (2) to a particular word processor format. The system loads a parameter activation table which sets document parameter values to allow DTDs to be automatically implemented. The document is cleaned (5) and tagged (6). The tagging provides an important link to allow automatic conversion at a later stage in the process. There is copy-editing (7) followed by validation of the file preparation stage. The involves automatic validation of tags, including validation of their order and nesting arrangement. Automatic conversion to SGML is performed in sequence of symbol/character conversion (20), tag conversion (21), equation processing(22), and floating element processing (23). Final validation (24) is then performed.

  • Patent number: 6092567
    Abstract: A method and apparatus for producing a pharmaceutical product in a micronised form. The pharmaceutical product is delivered at a predetermined flow rate from a gravimetric feeding device into a delivery line. An air compressor generates an air stream which is delivered along an airline into which the pharmaceutical product delivery line is discharged for delivering the product to a microniser which micronises the product to a desired size range. The micronised product is delivered through a cyclone filter apparatus from which the micronised product is collected through an outlet valve to a storage drum.
