Abstract: A system and method for modulating optogenetic vagus neurons in a noninvasive and transcutaneous manner is disclosed. The system and method comprises a two-dimensional array of organic light emitting diodes (OLEDs), a voltage-generating unit, a control unit, and a feedback loop. The array is placed on a subject's outer ear. Because the array is flexible, it can be closely placed on the skin of the outer ear. The array can deliver optical therapy and monitor heart rate variability (HRV) of the subject simultaneously, and the pixels of the array can be individually addressed. The voltage-generating unit generates pulsed voltage to the OLEDs. The control unit is connected to the array and controls the array and therapeutic patterns. The feedback loop uses the HRV to identify the therapeutic patterns.

Abstract: The invention provides an easy to assemble railing assembly used for residential and commercial purposes. The railing assembly includes a plurality of locking components, a plurality of upright members and a plurality of locking pins. A locking component includes a plurality of wedge shaped locking slots. An upright member is configured to receive the locking component therewithin. The locking pin of the plurality of locking pins has each end connected to one or more wedge shaped locking slots of the plurality of wedge shaped locking slots.

Abstract: A reptile habitat assembly having a knock-down frame formed of a plurality of structural members joined by corner connectors. The rectangular framework is covered by a fabric screen enclosure having zippered flap at one end, which permits the framework to be inserted into the fabric cover as a unit the its fully assembled condition. Snap-fit, one-piece plastic floor and back panels mount to the tubular framework, and have receptacles for holding water, food, plants, and other features to create a naturalistic appearance. The screen covered frame structure is lightweight and shrinkable, using connectors between vertically-adjoining corner members, and the knock-down construction facilitates compact packaging for shipment, storage, and point of sale display.
