Abstract: A fuel cell system includes a fuel cell generator, a rechargeable energy storage circuit, an auxiliary load, a converter circuit, and a switch circuit. The fuel cell generator is operable to generate electrical power in a stack output signal. The auxiliary load is powered by the rechargeable energy storage circuit while in a first mode, and powered by a local signal while in a second mode. The converter circuit is operable to convert the stack output signal into a plurality of recharge signals while in the first mode and in the second mode, and convert the stack output signal into the local signal while in the second mode. The switch circuit is operable switch the plurality of recharge signals to one or more electric vehicles, and switch the local signal to the auxiliary load while in the second mode.

Abstract: A method of task and memory assistance using a mobile communication device can include storing a profile of a user and determining a task to be performed by the user based on the user profile. The method can also include notifying the mobile communication device of the task. The method can further include providing sensory indicators in an increasing order of intervention until an acknowledgement is received from user, or for a predetermined number of notifications.

Abstract: A method of remote surveillance and assisted care using a mobile communication device can include determining a location of a user. The method can also include adjusting at least one camera according to the location, and capturing an image of an area around the location. Further, the method can include transmitting the image to a remote information processing system.

Abstract: Footwear with a sole portion for protecting the lower surface of a foot only and support means for slidably receiving the foot for securing the footwear thereto while leaving the toes, heel, and ankle entirely exposed is provided with a pocket on or in the support means opening outwardly to permit insertion and removal of small items. A closure means at the opening of the pocket permits selective restricting of access to the pocket. In one embodiment the pocket is formed in the space between two superimposed layers of material comprising the support means, and the opening of the pocket is formed in the one of the two layers outermost from the foot of the wearer.

Abstract: A board-type fence which is of substantially identical appearance on both sides and which eliminates the need for nails in the construction thereof. The fence comprises a plurality of fence panels and fence posts. Each fence panel is constructed by passing a pair of spaced parallel rods through a predetermined number of fence boards arranged in aligned side-to-side relation with the rod ends projecting outwardly from the sides of each panel. Each fence post is provided with two pairs of holes that are horizontally offset from each other, the holes of each set being spaced apart a distance exactly equal to the rod spacing of each panel; thus, with regard to a given fence post, the rod ends of a first panel will project into one pair of spaced holes in that fence post whereas the rod ends of the other fence panel will project inwardly into the other pair of spaced holes on the opposite side of the fence post.
