Abstract: An integrated Internet camera includes, an infrared sensor, an optical system for forming an image on the infrared sensor and lenses formed from infrared transmitting material, an image capturing circuit, for capturing digital images from the infrared sensor; a network interface device connectible to a computer network for transmission of the digital images, as digital image files, across the computer network. A file transfer device of the camera communicates, via the network interface device, with a destination computer at a selected network address on the computer network, and transfers the digital image files to the destination computer according to a predetermined file transfer protocol. A transport control device of the camera controls addressing of the digital image files to the selected network address. The camera self-initiates a connection with the computer network and a connection with the destination computer at the selected network address.

Abstract: A facility comprising systems, methods, and techniques for collecting data indicative of energy consumption and/or energy production by energy systems and devices and providing the data to interested users and devices in real-time is described. The facility may comprise an energy gateway device coupled to one or more monitored devices, one or more energy data extraction servers, and one or more client computers.

Abstract: Low metal, low water biomass-derived pyrolysis oils and methods for producing the same are provided. Metal- and water-containing biomass-derived pyrolysis oil is contacted with an acidic ion-exchange resin having sulfonic acid groups to produce a low metal, water-containing biomass-derived pyrolysis oil. The low metal, water-containing biomass-derived pyrolysis oil is removed from the spent ion-exchange resin after ion-exchange. The low metal, water-containing biomass-derived pyrolysis oil is distilled to produce a low metal, low water biomass-derived pyrolysis oil and a distillation product. The distillation product comprises one or both of an alcohol ion-exchange regenerant and an acidic ion-exchange regenerant which may be used to regenerate the spent ion-exchange resin. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.

The network interface device may be a modem, network adapter, or adapter for connection to the Internet. Upon capturing the digital image, the camera initiates a connection to the Internet, connects to the destination user directory, and uploads the digital images. Thereafter, the digital images are available to authorized (or any) user having access to the Internet.
