Abstract: A location-based service is provided that allows a user of a mobile device to tag and track the places he or she visits and share these places with social networking members. To implement this service a system receives location information from the user's location-aware mobile device over a wireless network. The location information identifies various locations or other points-of-interest that the user has visited. Based on this information the system determines a geographical domain that encompasses at least some of the locations the user has visited. Once a geographic domain has been determined it is presented to the user via the mobile device. The user is prompted to tag the geographical domain with an annotation that describes the geographic domain. The system stores the geographical domain and the annotation associated therewith so that it can be searched and accessed or retrieved by the user or members of the user's social network.

Abstract: A voltage controlled delay line (VCDL) for measuring the maximum speed of a chip includes a first input configured to receive a reference clock signal, a first output configured to output an output clock signal, and a second input configured to receive a phase error signal representing a phase delay between the reference and output clock signals. A register stores a delay code applied by the VCDL to the reference clock signal to delay the reference clock signal to generate the output clock signal. The delay code is adjusted according to the phase error signal until the phase delay is equal to a predetermined value. A second output is coupled to an interface that reads the delay code from the register and outputs the delay code to automated testing equipment when the phase delay is equal to the predetermined value. The outputted delay code corresponds to the maximum chip speed.
