The present invention relates to an immersion lithographic system for patterning a work piece arranged at an image plane and covered at least partly with a layer sensitive to electromagnetic radiation. Said system comprising a source emitting electromagnetic radiation onto an object plane, a mask, adapted to receive and modulate said electromagnetic radiation at said object plane and to relay said electromagnetic radiation toward said work piece, and an immersion medium contacting at least a portion of a final lens of said lithographic system and a portion of said work piece, wherein an area of said contacting is restricted by capillary forces. The invention further relates to a method for patterning a workpiece.

A short-range wireless power transmission and reception system and method are provided. Power is transmitted from the electrical utility mains power supply to electrically powered appliances via electromagnetic radiation. The appliances are capable of receiving the transmitted power, converting it into electricity and storing it for subsequent use, as well as using it directly to power the appliances.

Process, materials, and equipment for producing three-dimensional objects from a particulate material by melting and adhering, for example, by fusion or sintering, portions of the particulate material.

An inductively coupled power and data transmission system include a main power source, apparel having an electrical conductor in electrical communication with the main power source, the apparel having a first inductively couplable power and data transmission sub-system to regulate power to the primary coil or coils and transmission of power and data by the primary coil or coils and reception of data by the primary coil or coils, and an independent device having a second inductively couplable power and data transmission sub-system so as to regulate reception of power and data by the secondary coil or coils and transmission of data from a secondary processor by the secondary coil or coils. The first and second primary coils transfer said power and data during inductive coupling, at electromagnetic radiation frequencies, between the first primary coil or coils and the secondary coil or coils.

A liquid immersion photolithography system includes an exposure system that exposes a substrate with electromagnetic radiation and includes a projection optical system that focuses the electromagnetic radiation on the substrate. A liquid supply system provides liquid flow between the projection optical system and the substrate. An optional plurality of micronozzles are arranged around the periphery of one side of the projection optical system so as to provide a substantially uniform velocity distribution of the liquid flow in an area where the substrate is being exposed.

The present invention describes a process for producing a three-dimensional object, comprising: providing a material to be solidified, the material comprising a filler and a binder; delivering electromagnetic radiation and/or synergistic stimulation in a pattern or an image to a building region for solidifying said material; wherein said delivering of electromagnetic radiation and/or synergistic stimulation is performed selectively to a defined area or volume of said material to be solidified; and wherein an energy density of electromagnetic radiation and/or synergistic stimulation is varied within said pattern or image and/or between patterns or images of different building regions of said material. The present invention may be directed also to a system where different first and second materials are to be solidified. The present invention further provides a freeform fabrication system, and a freeform three-dimensional object having unique properties as well as products derived therefrom, such as sintered products.

The present invention discloses a novel, user-wearable system for monitoring the oxygen concentration, or oxygenation trend, in the tissue of a subject undergoing aerobic stress. The system comprises a lightweight detector, worn against the skin surface of the subject, at the site being monitored. The system further includes wearable power pack and display means for displaying information indicative of the metabolic condition of the region being monitored. The detector preferably employs a continuous wave spectrophotometer having one or more sources of electromagnetic radiation with wavelengths between about 760 and 800 nanometers directed into the tissue of the subject. The detector utilizes photon migration to detect the portion of the transmitted radiation arriving at an adjacent skin region. The present invention also discloses methods for displaying the aerobic metabolic condition of a subject.

A method for energy-assisted atomic layer deposition and removal of a dielectric film are provided. In one embodiment a substrate is placed into a reaction chamber and a gaseous precursor is introduced into the reaction chamber. Energy is provide by a pulse of electromagnetic radiation which forms radical species of the gaseous precursor. The radical species react with the surface of the substrate to form a radical terminated surface on the substrate. The reaction chamber is purged and a second gaseous precursor is introduced. A second electromagnetic radiation pulse is initiated and forms second radical species. The second radical species of the second gas react with the surface to form a film on the substrate. Alternately, the gaseous species can be chosen to produce radicals that result in the removal of material from the surface of the substrate.
