Abstract: Some examples include a secure low-power sensor platform able to be used for activity monitoring or other purposes. For instance, a sensor system may sense sparse signals using compressed sensing. As one example, compressed sensing may be used to obtain sparse signals from analog sensor signals received from one or more sensors. The data obtained by compressed sensing may be sent subsequently to a computing device to reconstruct the sensor signal. Examples herein enable lower power usage, lower cost, and lower weight than conventional devices, while also enabling processing advantages, such as less overall data to process and lower data storage utilization.

Abstract: A computer-implemented method implemented via the Internet for coordinating a current or future event between a user of a mobile Internet device and other users communicating through the Internet. The method includes receiving the current or future activity information pertaining to the future event from the user via the mobile Internet device. The current activity pertains to an activity occurring at a current time relative to a time the future activity information is received. The future activity pertains to an activity occurring at a future time relative to a time the future activity information is received. The method further includes transmitting the current or future activity information to a backend database coupled to the Internet, the backend database being remote from the mobile Internet device. The method further includes rendering the current or future activity information accessible to at least one recipient via the Internet.

Abstract: A computer-implemented method receiving receives information describing a current or future activity from a user of a computing system via a mobile device. The current activity is an activity occurring at a current time when the information is received, while the future activity is an activity occurring at a future time relative to a time when the information is received. The method transmits the information describing the current or future activity to a backend database coupled to the Internet and remote from the mobile device. The information describing the current or future activity is accessible to at least one recipient having access privilege to information associated with the user and describing the current or future activity via the Internet.
