Abstract: An electric vehicle charger that comprises a display screen, an input power cable, an output power cable with a plug, a removable motherboard that houses the electronics of the charging circuit, a set of screws holding the motherboard to the enclosure, and a camera. The camera is mounted at the front of the display. The display is a touchscreen-capable display that shows content that can be provided wirelessly. The motherboard is attached to a racking mechanism that allows it to be removed from the charging station. When removed, the motherboard can be repaired or replaced with a new motherboard of the same capability or a new motherboard with improved capabilities. This process can be done while the charger is installed in the field. A real-time electric charger monitoring system is also implemented that can monitor operational parameters of the electric vehicle charger in real-time to ensure optimal function.

Abstract: Stable, low odor, hospital grade, non-bleach, decontaminating sporicidal disinfectant compositions and consumer products comprising such compositions are provided. The sporicidal disinfectant compositions comprise hydrogen peroxide and tetraacetylethylenediamine (TAED) and provide a solution of peracetic acid (PAA) for use in decontaminating articles and surfaces. Methods of preparing and applying consumer products, such as disinfecting sprays and ready-to-use wipes, are also provided.

Abstract: A drainage system, comprising a collector which is arranged to collect liquid and a drainage pipe having a pipe inlet that opens into the collector such that liquid collected by the collector drains through the pipe inlet. The drainage pipe is provided with a vent spaced away from the pipe inlet. The vent is arranged such that, when liquid collected by the collector occludes the pipe inlet, liquid flowing through the drainage pipe draws air into the drainage pipe through the vent.

Abstract: A method of configuring a vortex flow control device 2 comprising a vortex chamber 4, an inlet 6 and an outlet 8 arranged at one end of the vortex chamber 4, wherein the method comprises the steps of: setting a target maximum flow rate FT-MAX through the outlet 8 for a predetermined pressure PT-MAX at the inlet; setting a target vortex initiation flow rate FT-VI through the outlet 8 at which vortex flow within the vortex chamber 4 initiates; determining the actual maximum flow rate FA-MAX through the outlet 8 for the predetermined pressure PT-MAX at the inlet 6; determining the actual vortex initiation flow rate FA-VI through the outlet 8; determining an error parameter E based on at least one of the actual maximum flow rate FA-MAX and the actual vortex initiation flow rate FA-VI and at least one of the target maximum flow rate FT-MAX and the target vortex initiation flow rate FT-VI; comparing the error parameter E against a target condition CT; and, if the error parameter E fails to satisfy the target condit

Abstract: A flow regulating device 2 comprising a plurality of coaxial vortex chambers 16, 116, 216, 316 disposed in flow series. Each vortex chamber 16, 116, 216, 316 has an inlet 22, 122, 222, 322 disposed to promote rotational flow within the vortex chamber 16, 116, 216, 316, and an outlet 24, 124, 224, 324. A diffusion chamber 12, 112, 212 is disposed between adjacent vortex chambers 16, 116, 216, 316, and the outlet 24, 124, 224, 324 of one and the inlet 22, 122, 222, 322 of the other of the adjacent vortex chambers 16, 116, 216, 316 open into the diffusion chamber 12, 112, 212.
