A light emitting cover which inactivates microorganisms for covering a high touch surface is disclosed. The light emitting cover includes a body having an interior configured to cover at least a portion of the high touch surface and an exterior surface configured to be disinfected. At least an exterior portion of the body is transparent or translucent. A light emitter operably is coupled to the body for emitting a light through the exterior surface. The light exiting the exterior surface has at least a portion thereof having a wavelength in a range of 380 to 420 nanometers to disinfect the exterior surface.

A system and method for cleaning and disinfecting handrail, a robot and passenger conveying equipment. The system for cleaning and disinfecting handrail has at least one robot, the robot including: a travelling device configured to enable the robot to travel along a target trajectory, a cleaning and disinfecting device configured to perform cleaning and disinfection operations on a target object, and a controller connected to the travelling device and the cleaning and disinfecting device and configured to control operation of the travelling device according to command signals such that the robot travels to a target position of the passenger conveying equipment along the target trajectory, and to control the cleaning and disinfecting device to perform cleaning and disinfection operations on the handrail at the target position.

An escalator handrail washing device according to one embodiment of the present invention comprises: a case that accommodates an escalator handrail and a washing unit; a self-generation unit, arranged in the case, for converting kinetic energy of the escalator handrail into electric energy; and a communication unit for transferring information on an operating state of the escalator handrail to a control center. The washing unit includes a plurality of rollers. At least one roller is rotated without power, by frictional force generated by contacting a surface of the escalator handrail, in a first direction which is a reverse direction of a preset rotating direction of the escalator handrail. Other rollers are rotated by rotational force of the at least one roller. The other rollers can sterilize or wash the escalator handrail while rotating.

A system, apparatus, and methods are configured for cleaning and conditioning handrails. A cleaning pad is curved to approximate the shape of a handrail, and is disposed on an arm. The arm may be mounted on a support structure, allowing it to be rolled up to an escalator handrail and left to do the cleaning while the escalator runs. When mounted, the arm may include a spring or piston to keep the arm in a particular position. A second cleaning pad may be included to dry or polish the handrail, the handrail going first through the cleaning pad and second through the drying pad. The arm may be hand-held, allowing a user to reach up or down steps or an incline. The cleaning pad may be mounted such that it rotates about the arm for storage, maintenance or better reach, such as around bends or corners.

Various devices for sterilizing a surface and an object in contact with the surface are disclosed. For example, a first device includes an ultraviolet light source, a touch sensor, a processing system, and a computer-readable medium. The computer-readable medium stores instructions which, when executed by the processing system, cause the processing system to perform operations that include detecting, via the touch sensor, a tactile state of the device, detecting a tactile state of at least one additional device, determining, based upon the tactile states, that the device is on an edge of a pattern of contact between an object and a surface comprising the device and the at least one additional device, and implementing an action associated with the ultraviolet light source in response to determining that the device is on the edge of the pattern of contact.
