To fully understand this, you have to be familiar with the rules module. Lots of documentation can be found on http://drupal.org/node/298480 for an introduction and tutorial, but http://drupal.org/node/298486 is a lot of handy info for developers.

Code

function heartbeat_block($op = 'list', $delta = 0) {
  if (user_access('heartbeat view messages')) {
    switch ($op) {
      case 'list':
        $blocks[0]['info'] = t('Personal heartbeat');
        $blocks[0]['cache'] = BLOCK_NO_CACHE;
        return $blocks;
      case 'view':
        if (variable_get('heartbeat_enabled', 1)) {
          global $user, $language;
          $max_gap = variable_get('user_activity_grouping_seconds', 3600);
          $end_time = $_SERVER['REQUEST_TIME'] - (int) $max_gap;

          // Retrieve the most receent heartbeat.
          $messages = array();

          // We really need every field
          $sql = "SELECT * FROM {user_activity} WHERE \n\t        (user_activity.uid = %d) AND (user_activity.language = '%s') AND timestamp > %d ORDER BY timestamp DESC";
          $result = db_query($sql, $user->uid, $language->language, $end_time);
          while ($heartbeat = db_fetch_object($result)) {
            $messages[] = $heartbeat;
          }
          $block['subject'] = t('Recent heartbeat');
          $messages = heartbeat_group_messages($messages);
          $block['content'] = theme('heartbeat_block', $messages);
          return $block;
        }
