Abstract: A safety and security device is housed on either an unmanned aerial vehicle or its land-based docking station and is combined with a cellular telephone for self-defense purposes. The phone broadcasts both recorded audio and video warnings on the device. A flashing light may be activated on the aerial platform or the docking station. The device may be integrated into a modular unit that combines numerous defensive mechanisms. These defensive mechanisms operate autonomously and respond to perceived threats.

Abstract: The present disclosure provides a way to enhance the photoconductivity and/or the SPF of a semiconductor. By dispersing the semiconductor with a compound having multiple phenyl groups in a polar carrier oil, the semiconductor exhibits greatly improved photoconductivity and/or SPF over dispersions comprising the semiconductor alone.

Abstract: A composition comprising a physical sunscreen, one or more adjuvants, and a carrier oil is provided. The composition also includes at least one of a compound having multiple phenyl groups, a film former or dispersant, and a silicone surfactant. The composition may also include an organic sunscreen. The combination of these ingredients exhibits an unexpected synergistic effect, in that the photoactive properties of the composition (e.g., SPF, UV absorption) are significantly higher than would be predicted based on the values for each of the components individually.
