The aerated pad may receive a bulk material to be composted into a compost product. The aerated pad may comprise an air nozzle and a drain to direct water from the bulk material to a water collection system. The pivot arm may deposit the bulk material on the aerated pad. The control module may manage a temperature inside the bulk material using the air nozzle.

Abstract: A system for detecting a living being using electric fields may include sensors configured to generate and receive an electric field. The system may include at least one amplifier connected to at least one electrode of a sensor, a controller to operate the sensors, and a processor connected to the controller. The processor may output a signal representative of the presence or absence of a living being present in the electric fields or representative of a distance between the sensor and the living being. The sensors may be attached to a rigid or flexible substrate forming part of a skin that can be attached to a robot, a vehicle, or another moving or autonomous device to sense the presence of a living being near the device. The device may be configured to stop moving or to move to avoid the living being in the electric field.

Abstract: The invention relates to a method of patterning a layer formed from a fixable material such as photopolymer on a surface in a desired pattern. The method involves coating selected areas of the substrate with an adhesion promoter and subsequently coating the fixable material. The fixable material is then fixed, for instance by curing by exposure to UV radiation. The adhesion promoter is adapted to have a surface energy which is designed to adhere to the substrate or selected areas thereof and also to the fixed material such that fixed material may be easily removed from areas of the substrate not coated with adhesion promoter but retained in areas where the adhesion promoter has bonded to the substrate.

Abstract: The current application is directed to systems and methods for processing organic waste using aerobic bacterial digestion of organic waste. In one implementation, the system includes a covered enclosure with a non-porous floor and sidewalls within which a floor-scraping, helical auger with serrated or toothed edges is mechanically powered and translated in two dimensions in order to chop, mix, lift, and move composting organic waste towards a discharge end of the enclosure. The vessel additionally includes a rotatably mounted screen, in one implementation, for screening the composted organic waste as it is discharged. The vessel additionally includes, in one implementation, perforated, pressurized tubes for introducing pressurized air into the organic waste as it is processed as well as a flexible water hose for introducing moisture into the organic waste as it is being processed.

Abstract: A photopolymer mixture is capable of use for a liquid crystal alignment layer. An alignment layer is formed from such a photopolymer mixture. The mixture comprises at least two polymerisable materials which are blended together in proportion so as to give a predetermined, preferably low, surface energy. A low surface energy, e.g., less than 4×10?2 N/m, can result in an alignment layer which imparts a particular orientation to liquid crystal molecules with out requiring any post-cure treatments. The polymerisable materials may be monomers, oligomers, or diluents that form long chain molecules when cured, and the mixture may contain additives to lower the overall surface energy.

Abstract: A method for determining effective area coefficient for a pilot operated safety relief valve. The relief valve may have a piston with an upper surface area, an inlet, and a dome. The method may include determining a total force acting on the piston (Ftotal) and determining a downward force (Fdome) on the piston due to dome pressure. The method may further include determining an upward force on the piston due to inlet pressure (Fmain) by subtracting the downward force (Fdome) from the total force (Ftotal) and determining an instantaneous Effective Area coefficient (Ae) by dividing the upward force on the piston (Fmain) by a main inlet pressure (Pmain).

Abstract: A method and apparatus for forming a patterned layer having a surface profile that provides relief structures within an electronic device. The method comprises the steps of taking a carrier film (50) having an inverse of the required surface profile formed on one side thereof, taking a layer of fixable material (54) located on a substrate (52), laminating the carrier film (50) and substrate (52) such the carrier film causes the required surface profile to be formed in the layer of fixable material with a predetermined offset, and then fixing the fixable material. Lamination may be performed using rollers (56,58) or a vacuum process. The process is designed to ensure that the offset can be kept as low as possible, preferably to within 150 nm.
