Abstract: A device for the detection of a food allergen includes a sensor having a printed circuit board and a chip comprising a molecularly imprinted polymer (MIP) and a non-imprinted polymer (NIP); a reservoir comprising a liquid; and a chamber for mixing the liquid with a food.

Abstract: A compact precision illumination source mounts on a finger of a user for providing localized illumination for precision tasks such as surgical procedures and other tasks performed in dark or confined spaces. A frame having a circular or arcuate shape engages the finger, and secures an enclosure having a small but powerful bright, light focused on a predetermined region defined by the end of the digit that is likely the activity region for an instrument grasped by the digit. The frame engages a charge module for aligning external conductors for recharging a power supply in the illumination source.

Abstract: An apparatus including an electrical source and a circuit board. The electrical source includes an outer shell including a receptacle, a battery arranged within the outer shell, and at least one electrical connector electrically connected to the battery and extending through the outer shell. The circuit board includes at least one circuit element and a mounting post. When the mounting post of the circuit board is received within the receptacle of the outer shell, the at least one electrical connector of the electrical source is electrically coupled to the at least one circuit element of the circuit board.

Abstract: A phototherapy device, system, and method for treating acne and/or acne scarring, includes a light emitting device configured and arranged to emit light from a bottom surface thereof; and an attachment portion having an aperture therethrough configured to permit light through. The attachment portion is configured to retain the device to a user's skin and bathe the skin with phototherapeutic light from the light emitter. Attachment of the device may be preceded with the application of synergistic fluid, ointment, gel, cream, lotion, foam, soap, or other solutions which may or may not consist of known topical acne treatment agents, augment device attachment to the skin, and/or have photodynamic properties. The light emitted may be any wavelength, combinations of wavelengths, intensity, pulse frequency, and exposure duration.

Abstract: A refillable toddler sippy cup drinking container having a vertically disposed see-through window is provided.

Abstract: A sterilizer system includes a base having a chamber configured to hold water, a lid configured to cover the chamber, a switch coupled to the base and in communication with the lid, and circuitry in communication with the switch. The circuitry is configured to determine whether a sterilization cycle was interrupted. The sterilizer system further includes a status indicator configured to indicate whether the sterilization cycle was interrupted based on input from the circuitry.
