Abstract:
Devices (302, 702, 800) with embedded control programs are provided are provided with RF-ID devices (114, 504) or other non-contact read data carriers (604) that provide configuration data, on which the execution of the embedded control programs is contingent. Preferred embodiments include wireless communication devices (302, 702, 800) provided with RF-ID devices (114, 504) or set of magnets (604) that encodes data embedded in front fascia. Embodiments of the invention increase the security of configuration data, and allow for functionality to enhance by replacing the front fascia.
Abstract:
A method for humidifying a fuel stream for a direct methanol fuel cell. An ultrasonic transducer (122) is used to create a vapor of methanol without heating. Water is also vaporized with an ultrasonic transducer (132) to create a vapor of water without heating. The water vapor and the methanol vapor are combined (240) in a certain ratio to form a humidified fuel vapor which is presented to an anode (112) of the direct methanol fuel cell (110). The ratio of water to methanol can be adjusted automatically by a sensor (180) that monitors the current drawn by the load (170) on the fuel cell.

Abstract:
A method (50) of altering content provided to a user includes the steps of creating (60) a user profile based on past physiological measurements of the user, monitoring (74) at least one current physiological measurement of the user, and altering (82) the content provided to the user based on the user profile and the at least one current physiological measurement. The user profile can be created by recording a plurality of inferred or estimated emotional states (64) of the user which can include a time sequence of emotional states, stimulus contexts for such states, and a temporal relationship between the emotional state and the stimulus context. The content can be altered in response to the user profile and measured physiological state by altering at least one among an audio volume, a video sequence, a sound effect, a video effect, a difficulty level, a sequence of media presentation.
