A biological indicator with variable resistance may be controlled by moving a cap or housing of the biological indicator to cause the size of vents that allow flow of sterilant through the housing to decrease or increase in effective size. An indicator window may show a user the current resistance of the biological indicator, and may also show a readable indicator that may be captured by a scanner to allow a sterilizing cabinet to identify the current resistance. When the level of resistance shown by the readable indicator is not compatible with a sterilization cycle selected by a user, the procedure may be delayed and a notification provided to the user that a problem exists. The readable indicator may be a passive tag with a memory that allows information to be read and written, so that the biological indicator may carry data from one device to another.

A cleaner for a bed includes a cleaning body provided to be movable forward or backward with respect to a surface of a mattress of the bed to suck foreign matter from the mattress, and thus the mattress may be easily cleaned.

The disclosure relates to a sanitation and sanitization apparatus and methods for disinfecting a wearable equipment used in the catalyst reactor field including: a case having a first chamber and a second chamber; an internal assembly located within the first chamber of the case; a condenser within the internal assembly; an atomizer assembly within the internal assembly and connected to the condenser; a circulating pump within the internal assembly; an programmable logic controller configured to communicate with the condenser, atomizer, and circulating pump; and wherein the internal assembly has a housing containing the condenser, the atomizer assembly, the circulating pump, and the programmable logic controller; and a disinfectant port is defined on a side of the housing adjacent to the second chamber of the case.

A display apparatus, including a display panel; a touch sensor provided on the display panel and configured to detect a user touch input; an ultraviolet (UV) light source provided on an edge portion of the display panel and configured to emit UV light to the display panel from the edge portion of the display panel; and a controller electrically connected to the display panel, the touch sensor, and the UV light source, wherein the controller is configured to, based on a determination that the user touch input is not detected, control the UV light source to emit the UV light toward the display panel.

Ozone-based methods and systems for treatment of solid waste that contains pathogens, and requires apparent volume reduction, include using dual treatment chambers, lift transporters that cascade the preliminarily treated solid waste, and agitation within the second (high ozone concentration) treatment chamber. The steps include feeding solid waste into a shredder chamber to reduce its apparent volume; and then to a first treatment chamber for preliminary ozone molecular interaction with the solid waste, and to a second treatment chamber with an agitator, via at least one lift transporter, to both cascade and agitate to enhance efficacy.

A system and method are defined for disinfection of the structure, contents and included air in large volume enclosures such as mass transit vehicles, transport containers, warehouses, and retail sales or gathering locations to reduce the risk of transmission of contagious biological agents, particularly bacterial and viral agents. Various embodiments provide effective sanitizing actions accommodating differing local circumstances and obstacles. Safety interlock mechanisms, procedural steps and communications means ensure safe operations around humans and animals. The system includes a method for measuring environmental conditions to ensure a safe re-entry state.

A machine, a filtration system and a method for disinfection and purification in fuel tanks located in places with high humidity or high relative humidity, having a machine (1) with an inlet for the fuel from the tank, a filtration system of a coarse-grain filter (2) and a fine-grain filter (2′); a radiation chamber (3) configurable for the application of radiation to the filtered fuel; a pump (4); a flowmeter (5) with at least two electrovalves (17); a centrifuge (6) with a turbine filter (6′) and control via an electrical panel (7); a cleaning machine (1); a suction hose (8) with an extendable suction lance (9); a high-pressure discharge hose (11); a return hose (12); a system for the opening and sealing of the tank (25); and an automatic filter self-cleaning system which reverses the flow, sending the fouled fuel to an additional tank (14) where it is drained.

A vehicular sanitization control device includes a rechargeable internal power source, a deep ultraviolet light source, a first display light source configured to display an operating state of the deep ultraviolet light source, a second display light source configured to display a state of charge of the internal power source, and a control unit configured to control a power supplied to the deep ultraviolet light source, a charging operation of the internal power source, and displays of the first display light source and the second display light source, respectively.

A portable sanitization system may comprise: a portable device; a light source disposed in the portable device, the light source configured to emit a light having a wavelength between 414 and 474 nm; a light converter comprising a nonlinear crystal configured for frequency doubling; and a light guide extending from the light source to the light converter, the light converter disposed proximal a tip of the light guide.

A safe sterilization unit includes a bearing portion, a light source portion and at least one safety switch. The bearing portion includes two surfaces corresponding to each other; the light source portion is configured to generate sterilization light, and is disposed on one surface of the bearing portion; and the safety switch is disposed on one side surface, provided with the light source portion, of the bearing portion, and is connected with the light source portion. The safety switch is disposed to sense light to generate a sensing message, and to regulate power supply of the light source portion according to the sensing message.
