Abstract: A method and a system for detecting an adhesion of a relay are disclosed. In a high voltage circuit, a voltage is measured across a load multiple times within a specified time period when a first relay and a second relay are open and a third relay is closed, where the second relay may be a main negative relay of the high voltage circuit. The second relay is declared to have an adhesion malfunction when a change in the value of the measured load voltage satisfies a specified condition. Using the change in the sampled load voltages external to the main negative relay, the adhesion malfunction of the main negative relay may be diagnosed, so that corrective action may be taken. The potential safety hazard caused by the adhesion malfunction of the main negative relay may be prevented, such as may occur in an electric vehicle high voltage circuit.

Abstract: Collecting dimension data (e.g., height, chest size, etc.) associated with users and leveraging the dimension data to generate and display size distributions in association with products in an online marketplace is described. The size distributions may summarize data so that users may make sizing decisions based on users with similar user dimensions who acquired a same garment. The size distributions may summarize data so that a user may compare values corresponding to ranges of user dimensions in the context of a size of garment. The values may be determined based on adjusting a baseline value based at least in part on a number of users who acquire a garment, return a previously acquired garment, or provide negative feedback about the size of the garment. Graphical representations, such as pie charts, bar charts, etc., that are representative of the size distributions may be presented to users for providing contextual recommendations and/or information to streamline online shopping transactions.
