Disclosed are a device and method for generating electrical energy. The device has a fuel cell that converts hydrogen gas to electricity; and a fuel cartridge in fluid communication with the fuel cell and containing a fuel which reacts with water to form the hydrogen gas. The fuel comprises a solid metal or alloy, and the fuel cartridge is configured such that the rate of hydrogen gas generation decreases automatically without consuming electricity as demand for the hydrogen gas decreases.

A metal based hydrogen source contains metal such as Al, Zn, Mg that can react with water to produce hydrogen gas, borohydride such as sodium borohydride, potassium borohydride etc, and hydroxides such as NaOH and KOH etc. The hydrogen generation follows the following processes: First, metal aluminum reacts with water and hydroxide to produce hydrogen gas an heat, at the same time, hydroxide, the stabilizer of sodium borohydride, is consumed; As sodium borohydride is de-stabilized by the consuming of sodium hydroxide, hydrogen gas is produced through hydrolysis reaction of borohydride. The hydrolysis reaction can be accelerated by utilizing the heat that comes from aluminum's reaction with water. At the same time, hydroxides are partly or completely eliminated from the byproduct. The hydrogen gas produced may be used for any purpose.

Described here is a device for generating electrical current via an electrochemical fuel cell that consumes hydrogen. The described device may be entirely or partially self-contained or may be made up of cooperating components. The device comprises at least and fuel and fuel cell components and those components may be integrated. The fuel is selected to produce hydrogen suitable for use in a variety of fuel cell designs that utilize hydrogen to produce electrical current. The fuel cell, in some variations, produces water and that water may be returned to the selected fuel source to create a self-sustaining supply of hydrogen for the fuel cell under load. The fuel cell may also contain a system for controlling the amount of water produced by the fuel cell that gets delivered to the solid fuel.

A method and apparatus is described for recharging a fuel used to produce hydrogen for a hydrogen consuming device. The fuel can be NaBHwhich forms NaBOupon reacting with HO to produce hydrogen. The NaBOis converted to NaBHthrough a series of coupled chemical reactions which include reacting NaBOwith a metal and hydrogen to produce NaBHand oxidized metal. The oxidized metal can then be recycled using an electrolytic process which converts the oxidized metal to metal and oxygen. The apparatus includes a transport mechanism for removing the spent fuel such as NaBOfrom the hydrogen consuming device to the charger and delivering the recharged fuel, such as NaBH, back to the hydrogen consuming device.

Provided are integrated circuits and methods for transposing a tensor using processing element array operations. In some cases, it may be necessary to transpose elements of a tensor to perform a matrix operation. The tensor may be decomposed into blocks of data elements having dimensions consistent with the dimensions of a systolic array. An identity multiplication may be performed on each block of data elements loaded into a systolic array and the multiplication products summed in column partitions of a results buffer. The data elements in the column partitions of results buffer can then be mapped to row partitions of a buffer memory for further processing.

One embodiment can provide a home-automation system. The home-automation device can include a mechanical supporting structure and a plurality of components mechanically coupled to the mechanical supporting structure. The plurality of components can include a central controller, one or more printed circuit boards (PCBs), and a plurality of sensors mounted on the one or more PCBs. The central controller can be configured to detect a user event based on output from multiple sensors, with each sensor being configured to sense parameters in a different physical domain.
