  • Patent number: 11992313
    Abstract: Method and system for determining real time analyte concentration including an analyte sensor having a portion in fluid contact with an interstitial fluid under a skin layer, an on-body electronics including a housing coupled to the analyte sensor and configured for positioning on the skin layer, the on-body electronics housing including a plurality of electrical contacts , on the housing; and a data analysis unit having a data analysis unit housing and a plurality of probes , on the housing. Each of the probes configured to electrically couple to a respective electrical contact when the data analysis unit is positioned in physical contact with the on-body electronics. The one or more signals on the probes correspond to one or more of a substantially real time monitored analyte concentration level (MACL), MACL over a predetermined time period, or a rate of change of the MACL, or combinations thereof, are provided.

  • Publication number: 20240169207
    Abstract: Methods, systems, and computer-readable storage media for receiving a set of crash reports, determining a set of trace vectors by processing a set of stack traces through a first DL model, each trace vector in the set of trace vectors being a multi-dimensional vector representation of a stack trace of a respective crash report provided from the set of stack traces, generating a set of feature vectors by processing the set of trace vectors through a second DL model, each feature vector being a multi-dimensional vector representation of a stack trace of a respective crash report, and clustering each crash report in the set of crash reports into a group of a set of groups based on comparing feature vectors of respective crash reports, each group representative of a root cause resulting in respective crashes of the software system represented in one or more crash reports.

  • Patent number: 5052521
    Abstract: A stairway wheelchair lift includes a stationary motor drive unit, a rail assembly extending along the stairway and a mobile platform movable along the rail. A flexible drive member, such as a chain or cable, within the rail assembly, is driven by the motor drive unit and is connected to the mobile platform to move the platform in either direction along the rail. The mobile platform is adapted to support and transport a wheelchair-bound passenger during use, and to fold upwardly out of the way of the stairway when the lift is not in use. An automatically actuated brake mechanism stops further movement of the mobile platform when the speed of the platform relative to the rail exceeds a predetermined threshold, and a plurality of safety sensing switches prevent operation of the lift in the presence of obstructions along the stairway or other unsafe conditions.
