A germicidal device is disclosed. The germicidal device may include a flexible panel that can be rolled up and/or folded. A plurality of LEDs embedded in the panel and a plurality of lenses are embedded in the panel. The panel includes an input connector coupled to the panel that receives input at a first voltage from a power source. The LEDs are coupled to the input connector and provided a second voltage that is suitable for operating the LEDs. The panel also includes one or more output connectors on the panel. The output connectors provide the first voltage as an output voltage from the panel. The panel may be coupled to additional panels with the additional panels receiving the first (output) voltage from the first panel as input voltage to the additional panels.

According to an embodiment, an image forming apparatus supplies, in a normal mode, electric power to an image forming device, and limits, in a power saving mode, power supplying to the image forming device to be less than that in the normal mode. The image forming apparatus communicates, in the normal mode, with a germicidal lamp apparatus via a communication interface such that the germicidal lamp apparatus generates no germicidal light, and communicates, in the power saving mode, with the germicidal lamp apparatus via the communication interface such that the germicidal lamp apparatus generates germicidal light.

An HVAC system including a sterilization unit is provided, wherein in one embodiment the sterilization unit is located within the HVAC system. The sterilization unit includes a housing configured to envelop an outer side surface of the sterilization unit, an irradiation unit located on one side surface of the housing, and reflection units located in the housing so as to face the irradiation unit.

An apparatus and method of decreasing airborne pathogens is provided. The apparatus is an array of UV radiating elements. The array uses two or more different types of UV radiators and is adaptable for positioning within an HVAC system for treating circulating air. The apparatus is also adaptable for use in other environments and may be mounted on a mobile motorized base for transportation within a structure in accordance with a predetermined, variable route. The method involves positioning the apparatus in an environment to be treated and testing radiation pattern and intensity, which can be adjusted for optimal treatment of the ambient air.

Methods, systems, and apparatuses involving devices with disinfecting illumination are provided. An example apparatus comprises a container comprising a first side and a second side, a first array of light emitters disposed on the first side and configured to emit a first light within a wavelength range of 380-420 nanometers (nm) and having a first intensity, and a second array of light emitters disposed on the second side and configured to emit a second light within the wavelength range of 380-420 nm and having a second intensity, wherein the first intensity comprises an intensity sufficient to initiate inactivation of micro-organisms, and wherein the first array of light emitters and the second array of light emitters are configured to collectively create a multi-dimensional space of disinfection.

Devices, methods, and systems for disinfection with light are disclosed. In some examples, a lighting source is operable to provide light at wavelength range of about 380 nm - 420 nm with an irradiance and/or dosage sufficient for disinfection. One or more sensors and a control system may be used to control operation of the lighting source, such as by adjusting the lighting source in response to various inputs.

An electromagnetic radiation (EMR) delivery system for delivering EMR at wavelengths, intensities, exposures, and durations to locations inside and/or outside a patient's body in, on, and surrounding a catheter and/or a catheter extension to prevent, reduce, and/or eliminate infectious agents in, on, or surrounding the catheter and/or catheter extension. A smart light engine box generates the therapeutic EMR, controls treatments, and monitors the health of the system. A fiber optic disposable makes at-home use of the EMR delivery system possible. Specific embodiments of the EMR delivery system for use with peritoneal dialysis catheters, dialysis accesses, and hemodialysis accesses are also disclosed.

A device comprising a housing having a handle end and a treatment end. The treatment end is configured to provide an antimicrobial treatment and a heat treatment. The treatment end comprises an applicator having an applicator surface for providing at least the heat treatment. The device includes a heat generation unit configured to heat the applicator surface in use, a source of antimicrobial agent, and a control unit operatively connected to at least the heat generation unit for controlling the heat generation unit. The device can be a hand-held device and used to apply topical treatment to a treatment area of a subject.

Photosensitizers are incorporated into articles, such a personal protective equipment. A method of applying continuous and consistent light includes fitting the articles with light sources and optical fibers to apply light to the areas of the articles incorporated with the photosensitizers. Photosensitizers can be applied to articles by various applicators in either a gel or solution. A gel can be particularly effective when used on hydrophobic surfaces. Photodynamic reactor systems can be used to determine the effective doses of photosensitizers and the light dosimetry which can then be applied for use with the articles.

An osseointegrated fixture of a percutaneous osseointegrated prosthesis (POPs) anchors directly into a bone of a residual limb within an amputation stump. By anchoring directly into the bone, the POPs provides improved mobility, comfort, and function for an amputee, but an interface between an opening in the skin and the osseointegrated fixture, which allows the anchoring directly into the bone, is prone to infection by microbes. An anti-microbial device can be attached to and/or embedded within an extracorporeal portion of the osseointegrated fixture to irradiate at least a portion on the interface with at least one wavelength of light selected for its antimicrobial effects.
