Abstract: An air sanitation device may be utilized for sanitizing air particularly in environments where individuals may be in close proximity to one another. The device may include an internal chamber with an air inlet, an air outlet, and an air flow path defined between the inlet and the outlet. The chamber may be pressurized, for instances through an adjustable vacuum. The chamber may include one or more sources of sanitizing radiation, which may be a UV light emitter. Reflective coating may be provided around the internal chamber to improve the coverage of UV light, or other sanitizing radiation. The air flow path may follow a channel whose internal surface may include the reflective coating.

Abstract: A musical instrument support strap is integrated with a tuning sensor having of a body configured at one end for attachment to the musical instrument. The body carries the pitch of a musical note struck on the musical instrument and is detected by a pickup. A printed circuit board converts the detected pitch for display on a liquid crystal display module, preferably having a needle indicator and a color indicator. The sensor may be provided independently for attachment to an existing strap. The method of using the strap for tuning a musical instrument includes attaching the musical instrument support strap to a musical instrument; striking a note on the musical instrument; reading the measurement of the frequency of vibration on the liquid crystal display module; and, adjusting the musical instrument to change the frequency of vibration.
