Abstract: A method of resetting a password used for accessing a product device is provided, including receiving a password reset request from a user to reset a password for accessing the product device, the user having a prior registration to access the product device, generating a temporary password that uses information that is unique for each of the product device and the user and is signed using a cryptographic technique, and providing the signed password to the user for submission to and verification by the product device. The product device is configured to verify the signed temporary password using the cryptographic technique and using information that is unique for each of the product device and the user and that is known to the product device, and to allow the user access to the product device pending verification.

Abstract: An illuminative device (100) includes a control circuit (101), an acceleration detector (102) operable with the control circuit, and a plurality of light sources (103) operable with the control circuit. The control circuit is to receive an input (108) from the acceleration detector indicating deceleration (601) exceeds a predetermined threshold (662). Upon receipt of the input, the control circuit is to deliver a time-varying control signal to continuously illuminate the plurality of light sources with an illumination level varying between a first non-zero illumination level (664) and a second non-zero illumination level (665) in accordance with a frequency of the time-varying control signal.
