Abstract: A method and apparatus to collect user location data over time, correlating user location data with outbreak data. The method and apparatus further comprising an alert mechanism to indicate to a user if there was a potential exposure.

Abstract: A method and apparatus for a step counter system is described. The step counter system comprises an accelerometer to detect motion of a user, a step calculation logic to utilize the motion detected by the accelerometer to detect and count steps, and an incline logic to calculate an incline of a surface on which the user moved.

Abstract: A method and apparatus for identifying a raw target exercise level for a user and applying a goal setting algorithm to adjust the raw target exercise level for the user, the adjustment made in accordance with analysis of the user's data, and displaying an adjusted target exercise level to the user, in order to achieve the raw target exercise level for the user.

Abstract: A method for monitoring human activity using an inertial sensor includes continuously determining an orientation of the inertial sensor, assigning a dominant axis, updating the dominant axis as the orientation of the inertial sensor changes, and counting periodic human motions by monitoring accelerations relative to the dominant axis.

Abstract: A method and apparatus for a virtual accelerometer is described. The virtual accelerometer includes an active process identifier engine to identify any active application that may use accelerometer data. The virtual accelerometer also includes an intelligent signal interpretation and separation (ISIS) engine to separate raw accelerometer data for each of the active applications that use the accelerometer data. Additionally, the virtual accelerometer includes a universal application program interface (API) to provide separated accelerometer data to an application.

Abstract: A method of monitoring human activity includes monitoring accelerations using an inertial sensor disposed at one of a plurality of locations on a human body, wherein at least one of the plurality of locations is not a foot location. A plurality of steps are counted based on the accelerations. A gait characteristic of the plurality of steps is determined. The characteristic is used to determine a stride length. At least one of a distance traveled and a speed of travel are determined based on the stride length.

Abstract: A floor mat includes a housing for containing a power supply, speech module and speaker. A grid-like switching mechanism is closed upon a person stepping on the mat so as to provide an energizing current flow to the speech module. The speech module includes circuitry for recording and playing back a selected message. A slidable or releasable panel in the housing allows for selectable user access to the speech module. The housing precludes weather deterioration of the elements therein and cooperates with the switching mechanism so as to provide a user-selectable message to a person stepping on the mat. The mat/housing configuration allows alternative switching mechanisms to be used in connection with replaceable speech modules.
