Abstract: The present disclosure provides methods for generating percarboxylic acid compositions and/or peroxycarboxylic acid compositions formed external to a point of use in non-equilibrium reactions for use in certain bleaching and antimicrobial applications, in particular laundry applications. The compositions are generated external to a point of use, at alkaline pH levels, viz. greater than about pH 12, and optionally suitable for use with detergents and/or surfactants for synergistic bleaching efficacy. Methods of bleaching and/or disinfecting are further provided.

Abstract: The invention relates to a low temperature detergent composition of a first component for cleaning and disinfecting comprising: (a) about ?2 wt.-% to about ?50 wt.-% of a nonionic low alkoxylated alcohol tenside containing 1 to 2 alkylene oxide units; (b) about ?0 wt.-% to about ?60 wt.-% of nonionic higher alkoxylated alcohol tenside containing 3 to 40 alkylene oxide units; (c) about ?1 wt.-% to about ?60 wt.-% of a source of alkalinity; (d) about ?0 wt.-% to about ?95 wt.-% of at least one solvent; calculated on the total weight amount of the detergent composition of the first component. The invention relates further to a low temperature detergent composition for cleaning and disinfecting of a first component composition and a second component composition containing at least one bleaching agent.

Abstract: A method for sanitizing, disinfecting and bleaching laundry is provided. The method includes steps of applying an antimicrobial composition at a pH from about 4 to about 9 in an industrial laundry washing machine for effective antimicrobial efficacy, and thereafter applying a detergent use solution at an alkaline pH for removal of soil from the laundry, and optionally applying a bleach activator and/or catalyst to boost the bleaching component of the antimicrobial composition on the laundry, and lastly draining the antimicrobial composition, the detergent use solution and the bleach catalyst composition from the laundry.

Abstract: Devices that couple to high voltage transmission lines obtain power themselves using the body capacitance of an element of the devices. The devices generate a comparatively lower voltage from the current flowing between the high voltage line and the element of the device that generates the body capacitance. The devices can be used to operate sensors that monitor the transmission lines or parameters of the power distribution system, such as current, line temperature, vibration, and the like. The devices can also be used as indicators, such as aircraft warning lights, information signs, etc. In addition, the devices can operate as RF transmission/reception or repeater devices, radar devices, mesh networking nodes, video/audio surveillance, sound emitting devices for scaring animals, drones that traverse the power line, etc. Because the devices operate in response to line voltage rather than current, the devices are reliable even in low current conditions.

Abstract: An energy monitoring device including procedures for secure communication of data from the device is disclosed. The energy monitoring device includes a public/private key pair used to encrypt and/or digitally sign communications by the device. This allows the receivers of these communications to authenticate the communications to ensure that the device and/or communications have not been compromised. The energy monitoring device is further capable of communications via an ad-hoc “mesh” network, thereby facilitating communications among devices which are substantially inaccessible due to either physical or economic limitations.
