Abstract: A mobile software application implementing “live events,” via which a host of the event may sequentially offer one, two, three, four or more items to a plurality of guests in the event (e.g., via auction, via direct purchase, or via a giveaway). The host's device may obtain and transmit a real-time video stream, which is in turn provided to each guest's device in conjunction with real-time information about the item(s) being offered. Particular techniques further assist the host in sequencing two or more items to be offered in the same live event, thereby avoiding delays and cumbersome user interface interactions that might otherwise be involved in initiating the offering of a next item upon concluding an offering of a previous item.

Abstract: The carrier phase ready coherent acquisition of a global navigation satellite system (GNSS) snapshot signal includes receiving in a snapshot receiver different GNSS signals from correspondingly different GNSS satellites, and performing multi-hypothesis (MH) acquisition upon each of GNSS signal in order to produce a complete set of secondary code index hypotheses, each hypothesis producing a corresponding acquisition result according to an identified peak at a correct code-phase and Doppler frequency. The secondary code index hypotheses are adjusted for each different GNSS signal based upon a flight time difference determined for each GNSS satellite, so as to produce a new set of hypotheses. Finally, one of the hypotheses in the new set may be selected as a correct hypothesis according to a predominate common index amongst the hypotheses in the new set, and the acquisition results for each of the different GNSS signals may be filtered utilizing the correct hypothesis.
