Abstract: Disclosed are novel fused heterocyclic mescaline derivative compounds, notably fused heterocyclic mescaline derivatives and pharmaceutical and recreational drug formulations containing the same. Methods of making and using these compounds are also disclosed.

Abstract: A discrete semiconductor package includes a semiconductor device, a left lead, and a right lead. The semiconductor device has a first side and a second side, the second side being opposite the first side. The left lead has a left terminal and a platform to support the semiconductor device on the first side. The right lead has a right terminal and a clip coin to support the semiconductor device on the second side.

Abstract: A discrete power semiconductor package includes a semiconductor chip, a heatsink, a first lead, a second lead, and a clip. The heatsink is adjacent the semiconductor chip and draws heat away from the semiconductor chip. The clip binds the semiconductor chip to the heatsink and includes a chip linker, a first terminal, and a second terminal. The chip linker is atop the semiconductor chip. The first terminal connects to the first lead and the second terminal connects to the second lead.

Abstract: A vacuum cleaner attachment generally includes a cleaning element that floats relative to a suction conduit of the vacuum cleaner attachment. The cleaning element is supported on a support structure that is movably coupled to a housing and is biased towards a floor, for example, as a result of the weight of the cleaning element support structure. The cleaning element may be permanently attached to the support structure or may be a removable or disposable pad or sheet attached to the support structure. The floating cleaning element may be supported between the suction conduit and one or more wheels of the vacuum cleaner attachment. The vacuum cleaner attachment may be removably attached to a vacuum cleaner, for example, to be used interchangeably with other surface cleaning heads.

Abstract: A vacuum cleaner tool having a brush head, a rotatable duct, and a hinge. The rotatable duct is configured to receive a hose or wand and rotates about the hinge relative to the brush head, between a use position and storage position. In a storage position, the rotatable duct extends generally parallel, or in-line with the brush head and, in a use position, the rotatable duct extends generally perpendicular to the brush head. The vacuum cleaner tool may removably attach to the vacuum cleaner via a release on one end of the brush head interacting with a fixed catch on the vacuum cleaner.
