Abstract: A search system employs arrival times with associated confidence scores as search facets for identifying items. The search system identifies a plurality of items based on search input. An arrival time and associated confidence score are determined for each item from the plurality of items. Search results are provided for the plurality of items in response to the search input. The search results are provided based at least in part on the arrival times and associated confidence scores for the plurality of items.

Abstract: A search system generates custom attributes for use as search facets. User input associated with an image of a target item available on a listing platform is received. The image is analyzed to determine an attribute of the target item as a custom attribute. A value for the custom attribute is determined for each of a number of other items available on the listing platform that are of the same item type as the target item. Search results are provided based at least in part on the values of the custom attribute for the other items.

Abstract: A wearable device conveys information to a user. The device includes a master soft circuit cell and a plurality of actuation soft circuit cells. These cells are physically interconnected to form a garment that is worn by a user and each of these cells includes an electrically non-conductive fabric covering. Each of the actuation cells is electrically connected to and operates under the control of the master cell. The master cell is configured to wirelessly receive actuation instructions and activate a combination of the actuation cells based on the received actuation instructions. Each of the actuation cells is configured to generate a particular actuation that is perceived by one or more senses of the user whenever the actuation cell is activated by the master cell. A system also conveys affective state information to a user.

Abstract: A method of producing a polycarbodiimide polymer comprises heating a precursor compound at a desired temperature. The method further comprises combining the precursor compound, a diisocyanate compound, and a carbodiimidization catalyst to form a reaction mixture. Finally, the method comprises heating the reaction mixture for a first period of time at a first temperature, thereby reacting the precursor compound and the diisocyanate compound in the presence of the carbodiimidization catalyst to produce the polycarbodiimide polymer.
