A spa or hot tub stair assembly or apparatus having at least one step which is convertible by repositioning to provide different shaped sides. The basket may be used to retrieve material from a body. The construction may be formed in the shape of a box-like freight container in which the roof portion 2 andor the floor portion 3 provide structural integrity. A transistor includes a first sourcedrain, a second sourcedrain, a channel including a carbonated portion of a semiconductive substrate that contains SiC between the first and second sourcesdrains and a gate operationally associated with opposing sides of the channel. The base and the collector of said third bipolar transistor are respectively connected to the common node of said diodes and to said second supply voltage. In one embodiment, an electro-optical assembly includes a laser die having a laser device and a glass bridge electrically coupled with the laser die by one or more interconnect structures, the glass bridge including electrical routing features configured to route electrical signals to the laser die from a transmitter device.
