Abstract:
A method for forming printed conductors on a flexible substrate is disclosed. Initially, an inorganic matrix precursor is printed onto a flexible substrate. The inorganic precursor is then cured with a light pulse to form a porous inorganic matrix thin film. A polymer is subsequently infused into the porous inorganic matrix thin film to form a polymer infused inorganic matrix thin film.
Abstract:
A curing apparatus for thermally processing thin films on low-temperature substrates at high speeds is disclosed. The curing apparatus includes a strobe head, a strobe control module and a conveyor control module. The strobe control module controls the power, duration and repetition rate of a set of pulses generated by a flash lamp on the strobe head. The conveyor control module along with the strobe control module provide real-time synchronization between the repetition rate of the set of pulses and the speed at which the substrate is being moved under the strobe head, according to the speed information.
Abstract:
A gas discharge lamp has a gas and has a cathode, an anode, and an ignition electrode. Individual discharges of a series of lamp discharges are spaced at least one millisecond from each other, and the individual discharges are generated by providing an electrical charge between the cathode and the anode and providing two or more electrical pulses to the ignition electrode. The second and following electrical pulses occur within a predetermined time of the first pulse. The electrical charge between the cathode and anode is of sufficient voltage and current to create an electrical arc between the cathode and the anode with the gas is ionized.
Abstract:
Flashing lights powered by a common wild frequency power source (40) are synchronized with respect to flash rate and duration. Each lighthead includes a power supply device (1 ), which includes a timing signal generator (30) and a synchronization device (5). The timing signal generator (30) includes a precision clock (310), which generates a timing signal to regulate the flashing operation of the corresponding light. The synchronization device recurrently causes the timing signal to be reset in accordance with the wild frequency power source signal. By recurrently resetting the timing signal of each light according to a common wild frequency source, the flashing of the lights can be synchronized without transferring synchronization signals between the lights.
Abstract:
A high intensity discharge (HID) strobe lamp assembly including an HID lamp and circuitry arranged to maintain a current flow to the arc gap of the lamp throughout the powered operation of the lamp during strobing emissions as well as non-strobing operation. The lamp assembly thereby avoids problems incident to turn-on of the lamp for strobing emissions in prior lamps, in which long delay times between successive strobe emissions are necessary or high turn-on voltages are needed to flash the lamp. The lamp assembly of the invention avoids the requirement of long relaxation periods between successive strobe events and the need for high voltage conditions for strobing of the lamp, so that the lamp is able to operate in an efficient manner without generating EMI in the MegaHertz-GigaHertz range.
