Abstract: Some embodiments include an integrated structure having vertically-stacked conductive levels alternating with dielectric levels. A layer over the conductive levels includes silicon, nitrogen, and one or more of carbon, oxygen, boron and phosphorus. In some embodiments the vertically-stacked conductive levels are wordline levels within a NAND memory array. Some embodiments include an integrated structure having vertically-stacked conductive levels alternating with dielectric levels. Vertically-stacked NAND memory cells are along the conductive levels within a memory array region. A staircase region is proximate the memory array region. The staircase region has electrical contacts in one-to-one correspondence with the conductive levels. A layer is over the memory array region and over the staircase region. The layer includes silicon, nitrogen, and one or more of carbon, oxygen, boron and phosphorus.

Abstract: An automatic napkin dispenser includes a housing having a rotatable feed roller with protrusions on an outer surface thereof for engaging a topmost napkin on a stack of napkins, and displacing the topmost napkin between a pair of counterrotating nip rollers that dispense the topmost napkin to a customer. The housing includes a motion translating assembly coupled to the feed roller and moving the feed roller back and forth relative to at least one of the nip rollers.

Abstract: A power semiconductor bridge assembly for an alternator-fed DC power source, including positive and negative parallel spaced DC bus bars and a plurality of disk device phase modules disposed therebetween for interconnecting the bus bars with the alternator phase windings. The modules are mounted within the bus bars so as to facilitate their installation and removal. Each phase module includes a pair of disk-type power semiconductor devices separated by an inner heat sink which is connected to a motor phase winding, and sandwiched between first and second outer heat sinks. The semiconductor devices and various heat sinks are aligned along a mutual longitudinal axis which substantially coincides with a longitudinal axis of the bus bar cavity. The outer heat sinks are staggered or offset along a transverse axis of the cavity such that the first outer heat sink engages the positive DC bus bar, and the second outer heat sink engages the negative DC bus bar.

Abstract: A musical mat of the present invention includes a mat portion having a pillow connected to one end thereof. The mat includes a casing with a resilient padding material therein for supporting a person. A pair of speakers are mounted in the pillow and spaced apart so that a person can lie with his head between the speakers. A radio, or other audio transmitting device, is maintained in position within a pocket on the mat, and may be connected to a plug which is electrically connected to the speakers in the pillow, to transmit the audio signal to the speakers. The electrical conductor connecting the plug to the speakers is mounted within the mat casing and within the pillow, such that the wires do not interfere with the person lying on the mat. The pocket for retaining the audio transmitter is selectively fastened to the mat, to allow removal of the pocket and transmitter for use of the mat without the sound system.
