Abstract:
A method and system for indicating wireless interconnectivity between at least two electronic devices is useful for configuring wireless networks. The method includes activating at each device a wireless networking communication interface (step 305). At least one other device is then identified at each device (step 310). It is then determined at each device whether a wireless communication channel is operative with an identified at least one other device (step 315). An alarm is then triggered at each device that does not have a wireless communication channel operative with an identified at least one other device (step 320).
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 enhanced by replacing the front fascia.
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.
Abstract:
A method of and fuel cell system for limiting an amount of a fuel crossing over a membrane in a fuel cell, the method including determining an appropriate molecular ratio of the fuel and water for a fuel-water mixture 503; and controlling an amount of the fuel-water mixture that is available to an anode side of the membrane 507 in the fuel cell according to an amount of the fuel that will be electro-oxidized by the fuel cell. The fuel cell system includes a fuel cell membrane 103 having an anode layer 107, a cathode layer 109, and an electrolyte layer 111 where the cathode layer is exposed to an oxygen source, and a fuel delivery system 105 including a fuel chamber 119 disposed around and proximate to the anode layer at a side opposite to the electrolyte layer, the fuel delivery system implementing the method above.
Abstract:
A direct methanol fuel cell system 100 uses dissolved catalyst to promote a fuel cell reaction that takes place in an anode sub-chamber 110 of a fuel cell 102. According to the preferred embodiment the dissolved catalyst comprises a macro cyclic coordinated compound of platinum. The dissolved catalyst is preferably continuously circulated through the anode sub-chamber 110, and is preferably mixed in a mixing valve 118 with methanol and water in order to promote its catalytic action.

A housing (12) for use in a portable electronic device (10) includes an outer visible surface (14). The outer visible surface (14) is composed of an appearance changing substance responsive to an environmental stimulus.
Abstract:
A fuel cell (200) includes a membrane electrode assembly (210) located together with a layer of porous, z-axis electrically conductive, non-linear positive temperature coefficient (NPTC) material (250). The NPTC material (250) operates to selectively limit the amount of electrons collected from localized areas of the membrane electrode assembly (210) in order to reduce hot spots.
Abstract:
A system and method for merging static data and dynamic data downloaded to a browser from a network site of a network, preferably being a website on the Internet. The system includes at least one server in communication with the network, and the server hosts one or more network sites that include static data and dynamic data. The system further includes at least one user computer in communication with the network with a browser on the user computer that selectively interacts with network sites and selectively downloads the static data and dynamic data from the interacted network site. The user computer stores the static data and dynamic data in a local data store and recognizes the static data and dynamic data, preferably through marking with pointers, and upon refreshing of the downloaded data being requested, the user computer downloads dynamic data from the network site. The system provides a method including the steps of downloading static and dynamic data to the user computer from an interacted network site, recognizing the static data and dynamic data, storing the static data and dynamic data in a local data store of the user computer, requesting the refreshing of all downloaded data on the user computer from the network site, and downloading the dynamic data from the network site.
Abstract:
A method of diluting reacted fuel gas that is exhausted from a fuel cell. The reacted fuel gas is transferred from the fuel cell (10) into a hydrogen diluting mechanism (16) prior to release into the atmosphere, so that when the reacted fuel gas is subsequently released into the atmosphere, the percentage of hydrogen immediately surrounding the fuel cell does not exceed 4 percent by volume.
Abstract:
A method and apparatus for managing the performance of a fuel cell system (100) using an agitation means (150). The method of managing the performance involves, monitoring operational parameters (110) of individual fuel cells and the overall fuel cell system, comparing performance parameters (120) of the system against target values, selecting a control method (130) from a set of available control methods based on the result of comparison of the performance parameters against the target values and using that control method to initiate and control an agitation process, and actuating (140) an agitation means using the selected control method so as alter the monitored operational parameters (160).
