The wearable device includes a wearable housing and a transceiver attached to the wearable housing and configured to receive a first data item. The first data item is contact information or an event identifier. The transceiver is further configured to transmit a second data item. The second data item is contact information. The transceiver has an effective range of less than one meter. The transceiver is able to receive the first data item and transmit the second data item in less than three seconds. The wearable device also includes a memory configured to store the first data item and the second data item.

Abstract: A ring assembly including an annular body having an outer portion and an inner portion.

Abstract: This document describes a method and system for recommending items, such as beverages, that members of a group are likely to find appealing. When group members are identified, the system may identify one or more preference models for each member. Each preference model represents a pattern of dependency between characteristics of items that the member has rated and the member's ratings for those items. The system may develop a group preference profile by merging the patterns of dependency for each of the members into a group preference model. Then, when it receives a request for a recommendation for an item, the system uses the group preference profile to select, from a database, a candidate item having characteristics which are likely to appeal to many or all members of the group.
