摘要:
A transformable balcony table capable of attachment to a balcony rail includes a primary table assembly including a table top having a rear edge and a pair of side edges extending forwardly from the rear edge so as to form an apex opposite the rear edge The primary table assembly includes a mounting portion extending downwardly from the rear edge of the table top and defining a plurality of holes. A first stability member having a proximal end is removably coupled to the bottom surface and extends downwardly and rearwardly to a distal end. A fastener is selectively inserted through the slots of the mounting portion for coupling the mounting portion to the balcony rail. The balcony table includes a first and second leaf selectively coupled to respective side edges of the table top, the leaves transforming the table from two eating places to four.
摘要:
A power module is disclosed that includes a housing with an interior chamber wherein multiple switch modules are mounted within the interior chamber. The switch modules comprise multiple transistors and diodes that are interconnected to facilitate switching power to a load. In one embodiment, at least one of the switch modules supports a current density of at least 10 amperes per cm2.

A robot drive system preferably used for a vessel hull cleaning and/or inspection robot includes a first frame portion rotatably supporting a first axle with a first wheel thereon, and a second frame portion rotatably supporting a second axle with a second wheel thereon. A joint connects the first frame portion to the second frame portion and defines an expendable and contractible portion between the first frame portion and second frame portion. An actuator subsystem is configured expand and contract the expandable and contractible portion to move the first frame portion relative to the second frame portion at the joint to angle the first axle relative to the second axle to steer the robot.

A passivated semiconductor structure and associated method are disclosed. The structure includes a silicon carbide substrate or layer; an oxidation layer on the silicon carbide substrate for lowering the interface density between the silicon carbide substrate and the thermal oxidation layer; a first sputtered non-stoichiometric silicon nitride layer on the thermal oxidation layer for reducing parasitic capacitance and minimizing device trapping; a second sputtered non-stoichiometric silicon nitride layer on the first layer for positioning subsequent passivation layers further from the substrate without encapsulating the structure; a sputtered stoichiometric silicon nitride layer on the second sputtered layer for encapsulating the structure and for enhancing the hydrogen barrier properties of the passivation layers; and a chemical vapor deposited environmental barrier layer of stoichiometric silicon nitride for step coverage and crack prevention on the encapsulant layer.
摘要:
A transistor includes a protective layer having an opening extending therethrough on a substrate, and a gate electrode in the opening. First portions of the gate electrode laterally extend on surface portions of the protective layer outside the opening on opposite sides thereof, and second portions of the gate electrode are spaced apart from the protective layer and laterally extend beyond the first portions. Related devices are also discussed.
