Abstract: A therapy system includes a therapy output device that includes light sources and a controller. The light sources are configured to output electromagnetic radiation at different peak wavelengths. The controller is configured to operate the light sources to output the electromagnetic radiation to differ between a first therapy program and second therapy program by at least one of peak wavelengths, irradiance of one or more of the peak wavelengths, or energy density of the one or more peak wavelengths.

Abstract: A cleaning device includes an enclosure, an ozone-generating light source, a UVC germicidal light source, and a control system. The ozone-generating light source is configured to generate ozone in the enclosure. The UVC germicidal light source configured to emit UVC germicidal light in the enclosure. The control system is configured to, during a predetermined cleaning cycle, operate the ozone-generating light source for a first time period and to operate the UVC germicidal light source for a second time period, the second time period being at least 10 times longer than the first time period and terminating after the first time period.

Abstract: The following label is usable in kitchen environments. The label has a reusable surface layer, a contrasting structural layer, and an adhesive layer for adhering to storage and serving containers, such as bins, buckets, and trays. The label materials are waterproof so that the label is erased but not removed by routine washing of the storage containers.

Abstract: A protective device for mounting on and encasing a lock operating member, such as, a door knob to preclude access thereto and operation thereof. The casing includes a generally rectangular front opening through which the knob projects and a slide member vertically slidable therein which is adaptable to receive a locking means for securing the casing in position to prevent the locking mechanism of the knob from being actuated or removal of the knob.
