The present device provides a safe, effective means of mobile ultraviolet (UV) disinfection. A control board within the main body of the device receives data from sensors that may variously measure orientation and speed of the main body as it moves along various surfaces for disinfection. In response to such data, the control board may brighten, dim, or completely shut off UV light-emitting diodes (UVLEs), both to prevent over- and under-exposure of the materials being disinfected, and to prevent a user from unsafely using the device.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A photocatalyst filter is provided. The photocatalyst filter includes: a base in which an internal space is formed. The internal space is permeable to fluid, and a plurality of photocatalyst beads are provided in the internal space, wherein a surface of the internal space is reflective.

The invention is an air and surface disinfection robot designed to autonomously move through incredibly narrow spaces, specific to mass transportation vehicles such as aircraft, trains, busses, or ferries. The robot includes modes to operate in the spaces associated with transportation, such as waiting areas, bathrooms and narrow entry and exit ways.

In the transportation industry, turn around time (the time between two planned trips), is often incredibly short. Existing designs do not allow for a fast enough loading, setup and run time. This invention has been designed to optimize the portability, maneuverability, connectivity (data) and ease of use from other devices designed to disinfect such vehicles.

The invention uses UVC (germicidal) lamps, a proven technology for disinfecting pathogens. The design has been optimized by using a unique open cage design, so the light will transmit from all directions with minimal absorption to components on the device. This in combination with the lamp pattern and the robotics results in a very precise UVC light emission required for adequate, consistent disinfection of the surfaces and the air of mass transportation vehicles.

Finally, the invention consists of real time data streaming and remote operation as data is published through a connected cloud service and then onto the subscribed users.

A ventilator that moves breathable air into and out of the lungs of a patient. The ventilator includes an inspiratory circuit with an inlet, a bellows, and an outlet port for moving air into the lungs of the patient. An expiratory circuit includes an inlet port and a discharge port for moving the air out of the lungs. The inspiratory circuit is adjustable to control a number of breathes per time period and a volume of the breaths.

Proposed is a photocatalytic complex. The photocatalytic complex includes a photocatalyst, and an iodine compound layer formed on a surface of the photocatalyst to cover the same and containing an iodine compound. The present disclosure enables selective degradation of hydrophilic volatile organic compounds by the use of the photocatalyst coated with the iodine compound.

Disclosed are devices, systems and methods for air purification in an airflow tract of vacuum cleaners. In some aspects, an air purification system for a vacuum cleaner comprises an ultraviolet (UV) light unit disposed in a first location within the vacuum cleaner along an airflow pathway, configured to emit UV light at air containing particles including dust, dirt, and microbes while the air containing the particles is flowing in the airflow pathway where the UV light unit is disposed; and a particle filter unit disposed in a second location within the vacuum cleaner along the airflow pathway, the particle filter unit comprising one or both of a high-efficiency particulate air (HEPA) filter and an active carbon filter.
