The present disclosure provides a lamp for a medical operating area. The lamp includes a mounting assembly and a luminaire sterilization head. The luminaire sterilization head includes a vacuum, a first light source, and second light source. The vacuum generates a gas stream for evacuating a volume of the aerosol through the luminaire sterilization head. The first light source emits a visible light beam for illuminating the target. The second light source emits ultraviolet light waves along the gas stream for disinfecting the biological agent in the evacuated aerosol. The mounting assembly adjusts the separation distance between the luminaire sterilization head and the target of the medical procedure. The mounting assembly adjusts the orientation of the luminaire sterilization head to alter the angle of the visible light beam emitted by the first light source and the gas stream generated by the vacuum.

A wireless headlight assembly for attachment to an eyewear frame is disclosed. The wireless headlight assembly comprises a battery pod containing a battery connected to a lower housing element, which controls the application of power from the battery to an attached headlight assembly containing a headlight.

A powered wheelchair apparatus includes a chair component, a power base component and a wheelchair control system. The wheelchair control system includes a processor and a user input device communicatively coupled to the processor. A display is communicatively coupled to the processor. A memory module is communicatively coupled to the processor that stores logic that, when executed by the processor, causes the system to receive user instructions from the user input device and display a message on the display based on the user instructions. The display is on a back of the chair component.

A respiratory ventilation device—configured to send an airflow, generated by a fan, into a duct that extends between the device and a breathing mask configured to be worn by a user—comprises an air inlet intended to admit air into the device; a fan; and an air outlet configured to be connected to the duct, such that, when the fan is in operation, the air flows from the air inlet successively toward the fan and then toward the air outlet.
