Abstract: An ephemeral content distribution system associated with exchanging calibrated communications using a wave dynamic communication protocol based at least on a current wave-state of a user is disclosed. The system transmits a wave-based request for wave dynamic communications associated with a first user. The system processes wave-geographic information associated with a bounded geographical region based on a wave-state of a second user that received the wave-based request. The system processes wave-identity information associated with the wave-state of the second user. The system next receives a response of the second user to the wave-based request in accordance with the wave-state of the second user.

Abstract: Described are techniques for automatically generating tables or other types of output for comparing attributes of similar items. For each attribute of a particular item, a system may determine whether that attribute is generic to most items or specific to an item or category, whether data for that attribute is available for a sufficient number of items, and whether the value of that attribute differs among a sufficient number of items to facilitate a useful comparison. Responsive to user input, item data and one or more tables or other types of output may be provided to a user device. User input interacting with a table(s) or other output may be used to modify the stored table or output or to navigate to other tables, outputs, or item data.
