Abstract: Described herein are variations of an analyte monitoring system, including an analyte monitoring device. For example, an analyte monitoring device may include an implantable microneedle array for use in measuring one or more analytes (e.g., glucose), such as in a continuous manner. The microneedle array may include, for example, at least one microneedle including a tapered distal portion having an insulated distal apex, and an electrode on a surface of the tapered distal portion located proximal to the insulated distal apex. At least some of the microneedles may be electrically isolated such that one or more electrodes is individually addressable.

Abstract: Fault detection and diagnostics for a microneedle array based continuous analyte monitoring device are provided. The electrochemical sensors, including the electrodes of the analyte monitoring device configured for measuring one or more target analytes, may experience various faults during use of the analyte monitoring device. By modeling the sensors as an electrical network, measurements of the electrical network may be correlated with operational parameters of the sensor. The voltage at the counter electrode provides an indication of the resistance or impedance between the working electrode and the counter electrode and is used to identify the occurrence of faults occurring at the continuous analyte monitoring device.

Abstract: User selections entered in the media application or any user input device behavior with user devices may be recorded as clickstream data. The clickstream data may be used to deduce information about the user or a media item being consumed. A user may be profiled based on his or her input device behavior using a plurality of time-stamped indicators. A degree of user interest may be determined based on a time period between the time-stamped indicators, the number of time-stamped indicators within a period of time, and/or a type of user action.

Abstract: A flexure plate accelerometer system includes a flexure plate and two fixed plates on either side of the flexure plate. The flexure plate generates a flexure plate signal as a function of reference signals received in the fixed plates. A precision transformer generates the reference signals from a precision sine wave generated by a symbol generator controlled by a microprocessor. The microprocessor controls the symbol generator and activates an analog-to-digital converter in response to a signal coincident with a positive and negative peak of the precision sine wave. The analog-to-digital converter generates a digital word from the flexure plate signal, which is processed further in the microprocessor.

A processor receives the accelerometer signals and generates the platform control signal in response thereto.

A beam is rotatably coupled to the platform such that the beam rotates about the y-axis. An accelerometer including a flexure plate perpendicular to the y-axis is coupled to the beam a distance from the y-axis. The accelerometer generates an accelerometer signal in response to movement of the flexure plate. An angular position sensor senses angular position of the beam relative to the x-axis and y-axis, the angular position sensor generating an angular position signal therefrom. A processor receives the accelerometer signal and the angular position signal and generates an East-West signal therefrom.
