A compound light source that compensates for changes in electrical conversion efficiency with increasing operating temperature is disclosed. The invention is used to define some of the LAN ports, which are, for example, used to connect the switch into the IP router, as critical ones. The second pulse is applied during a refractory period associated with the first pulse. A communication system is supported on the computing device and is configured to communicate the assigned psychological mood state across an Internet to a web-site for positing on a web page. When the handover is complete, the LTE processor sends the transmission status of the set of IP packets to the DSP.
