  • Publication number: 20230298354
    Abstract: A method for monitoring and controlling a cleanliness of a space including: monitoring a distance of one or more individuals relative to an object within the space using a space monitoring system; determining when the distance is less than a selected distance; determining a number of the one or more individuals within the selected distance of object; determining a duration that the one or more individuals are within the selected distance of the object; and determining that the object requires a cleaning when at least one of: the number of the one or more individuals within the selected distance of object exceeds a threshold number, or the duration that the one or more individuals are within the selected distance of the object exceeds a threshold time.

  • Publication number: 20220311280
    Abstract: A method and an apparatus for wireless charging of batteries of electronic accessing devices. A method includes establishing a first connection between a battery of an accessing device and a receiver and a second connection between the accessing device and a transmitter, the transmitter and the receiver being associated with each other. The method further includes determining a charging status of the battery of the accessing device and communicating the charging status of the battery to the transmitter on determining that the charging status of the battery reaches below a predefined threshold value via the second connection. The method also includes charging the battery of the accessing device with power from the receiver using the first connection, wherein the receiver receives the power from the transmitter over the air.

  • Patent number: 10859262
    Abstract: A toxic waste incinerator is capable of enhanced combustion of hazardous waste (oil contaminated sand, human waste, garbage, etc.) utilizing immersed non-combustible and thermally conductive objects for increasing heat feedback from the flames to the unburned fuel, while air inlets are used to optimize the air entrainment rate to enhance the burning efficiency. The burning rate of a fluidic mass such as a sand-oil mixture is enhanced using immersed conductive objects (copper rods) which enable rapid heat-up of the flame exposed to the upper surface of the rod and transmits heat back into the sand. Consequent conduction of heat to the porous media through the lower portion of the immersed rod significantly increases vaporization and therefore the burning rate. Incineration may be performed on a transient, exigent basis as with hazardous waste and oil spills, or as part of a permanent fixture for receiving an ongoing waste stream.
