Abstract: This invention relates to a method of treating Attention-Deficit Hyperactivity Disorder by orally administering to a subject a composition containing a Radix Polygalae (Polygala tenuifolia Willd) extract (such as PDC-1421). A solid dosage form of the composition can be prepared into the gelatin capsule. The oral administration of the composition in healthy volunteers was safe and well-tolerated for the daily dose from 380 mg to 3800 mg. The composition can be administered chronically over at least 25 days; the daily dose is administered once per day, twice per day, or three times per day, wherein each dose is 380-760 mg of the botanical extract.

Abstract: This disclosure provides a portable lamp worn on the head and method of construction for the portable lamp. The construction method forms a composite structure that improves the comfort, reduces the volume, and better distributes the weight of the components of the lamp. The method of construction allows for a flexible material or set of flexible materials to be used to encapsulate the rigid parts of the headlamp. The flexible and rigid materials can be joined together in a heat press process that results in a single composite structure that has both attributes of the rigid material(s) and the flexible material(s) in different areas of the lamp. The battery can be located at the back or otherwise remote from the light to improve weight distribution and comfort for the user.

Abstract: A combustion device includes a combustion chamber with an outer wall enclosing a combustion space that can contain a fuel source on an adjustable fuel rack, side walls, a lower air jet tube and at least one air upper jet tube, a top opening, a grill top assembly to cover the opening, and a detachable power module. The power module can have batteries and a blower. The blower can force ambient air into a manifold, through the jet tubes, through ports in the jet tubes, and into the combustion chamber.

Abstract: A solar panel alignment device can include a first alignment feature capable of casting a shadow onto a target area. The first alignment feature can be located above a central portion of the target area. The target area can have a second alignment feature that can indicate the location of the central portion of the target area. A method for aligning a solar panel is comprised of the steps of the operator orienting the panel towards the sun so that sunlight strikes the first alignment feature so that the first alignment feature that interrupts the path of the sunlight, creating a cast shadow upon the target area; and the operator moving the panel so that the cast shadow moves to a central portion of the target area.
