Abstract: There is provided a method of generating a control strategy based on at least three switching states of a matrix converter. The at least three switching states are selected based on at least a predicted output current, associated with each switching state, and a desired output current. In particular, mathematical transformations of a desired output current as well as output currents associated with each of a plurality of switching states are used to identify appropriate switching states.

Abstract: The present invention concerns a new efficient method for the selective transformation, under mild conditions and in aqueous medium, of gaseous (ethane, propane and n-butane) and liquid (n-pentane, n-hexane, cyclopentane and cyclohexane) alkanes into carboxylic acids bearing one more carbon atom, characterized by a single-pot low-temperature (25-60° C.) reaction of the alkane with carbon monoxide in water/acetonitrile liquid medium, either in the absence or in the presence of a metal catalyst, in systems containing also an oxidant (a peroxodisulphate salt).

Abstract: The low-high chair provides a specially designed wheelchair with a seat that can be raised or lowered so that the wheelchair can be maneuvered in or out of a van without the risk of bumping someone's head on the roof of the van. The chair may also be adjusted for other purposes, such as driving a van, sitting at tables of various heights, or merely adjusting one's height to get a better view or be at the same height as one's contemporaries (e.g., at a movie theater or the like). The lift mechanism is operated by a pneumatic cylinder which is powered by an on-board compressed air tank. An inexpensive pneumatic valve may be used to raise or lower the chair, controlled by either the wheelchair user, or an assistant. The pneumatic tank may provide enough stored energy to raise and lower the user several times a day without recharging.
