Technologies are provided for analyzing packet loss in network packet streams using windowed loss durations. A computing device can be configured to detect a first loss period in a network packet stream and a second, subsequent loss period in the network packet stream. The computing device can determine a number of packets received in the stream between the two loss periods, and can compare this number of packets to a specified recovery window length. If the number of packets received between the two loss periods is less than the recovery window length, then the computing device can treat the two loss periods, and the packets received between the two loss periods, as a single period of packet loss. The packet loss period can be treated as a single loss event for the purposes of analyzing network packet stream quality of experience and/or tuning packet loss compensation mechanisms.

Network packet loss period expansion

Multiple device rests may be placed in different locations for use with a portable device such as a smartphone, tablet computer, controller, gaming device, etc. Upon being placed in one of the device rests, the portable device receives an identifier that identifies the particular device rest and/or the location of the device rest. In response, the portable device is configured to initiate an action that has been previously associated with the particular device rest and or its location.

Location-based device docking

Disclosed are various embodiments that are employed to ensure power source redundancy for a computing device. A plurality of power inputs of a computing device are coupled to at least one of a plurality of power sources. A determination is made as to whether at least two identifiers embodied in a corresponding at least two data signals transmitted over at least two power lines are the same. Each of the power lines is coupled to a respective one of the power inputs, and the data signals are transmitted by at least one of the power sources.
