Systems and methods for capturing and monitoring the health, safety, and/or activity of a user are described. In one aspect, the system generates a data usage pattern for the user and monitors the user's current data usage activity to detect data usage deviations from the user's usage pattern. When a deviation is detected, the system may send an alert message to the user or another user indicating that an anomaly may have occurred, permitting the user or another user to respond to the anomaly.

A method for processing a broadcast service at a Primary Device (PD), the method including performing, by a companion manager of the PD, a discovery process with a Companion Device (CD) application in a CD by receiving a discovery request from the CD and providing an endpoint for a WebSocket server of the PD; handling, by the WebSocket server, a connection established by the CD application based on the endpoint; in response to receiving a query for a current service from the CD, transmitting, by the WebSocket server, a response including information representing the current service to the CD application based on the connection; receiving, by a tuner, a broadcast signal having signaling information including flag information to obtain emergency data in the broadcast signal; time de-interleaving, by a time de-interleaver, Forward Error Correction (FEC) blocks including the emergency data based on a Time Interleaving (TI) block, wherein the FEC blocks are de-interleaved based on positions for the FEC blocks and one or more virtual FEC blocks; and transmitting, by the Websocket server, a notification message including the emergency data to the CD, in which the notification message includes a category for the emergency data.

In addition, the signaling information further includes information for a maximum number for the FEC blocks. The method also includes transmitting a notification message including the emergency data to the CD.

In response to an operation such as power-on or power-off, channel change and sound volume change, a television set combined with a personal computer automatically makes e-mail with information in a predetermined format indicative of the operation attached. The e-mail is automatically sent to another television set to inform the other television set of operation of the own television set. On the other hand, the e-mail can be sent to a rating company for audience share survey. The television set automatically reads the received e-mail and attachment to change the indication of display. The television set has storage of the received information for analysis of an abnormality. Abnormality can be also sensed through abnormal act on the remote controller apt to be taken by a person in panic or off the truck. The television set refuses information from unknown address for blocking an attack of a stranger.

Methods, apparatus, systems and articles of manufacture to correct attribution errors and coverage bias for digital audio ratings are disclosed. An example method includes applying, by executing an instruction with a processor, a duration-based count matrix to first demographic data associated with collected impressions of digital audio to determine second demographic data, the duration-based count matrix being based on a misattribution adjustment matrix, applying, by executing an instruction with the processor, a coverage adjustment vector to the second demographic data to determine third demographic data, applying, by executing an instruction with the processor, a scaling factor to the third demographic data to determine fourth demographic data, and generating, by executing an instruction with the processor, ratings data at a daypart-level using the fourth demographic data, the ratings data associated with the digital audio.
