Abstract: A headlamp illumination source that switches from a first configuration conforming to on-road illumination standards to a second configuration that does not conform to on-road illumination standards. The switching is preferably controlled by a wireless signal but in some embodiments the switching can be controlled by a hard-wired signal or by a switch proximate the illumination source itself.

Abstract: In a system for severing conductive links by laser irradiation to repair electronic devices, multiple laser beams are deflected at high-speed to target selected links for processing by positioning laser spots in a two dimensional pattern during relative motion of a substrate and a beam delivery system. As link targeting flexibility is increased, selection may be required from a large number of addressable link pairs. Various embodiments advantageously use beam deflection and beam splitting to improve memory repair processing rates.

Abstract: The invention provides a system and method for vaporizing a target structure on a substrate. According to the invention, a calculation is performed, as a function of wavelength, of an incident beam energy necessary to deposit unit energy in the target structure. Then, for the incident beam energy, the energy expected to be deposited in the substrate as a function of wavelength is calculated. A wavelength is identified that corresponds to a relatively low value of the energy expected to be deposited in the substrate, the low value being substantially less than a value of the energy expected to be deposited in the substrate at a higher wavelength. A laser system is provided configured to produce a laser output at the wavelength corresponding to the relatively low value of the energy expected to be deposited in the substrate.

Abstract: A laser polarization control apparatus includes a polarization modifying device, such as a liquid crystal variable retarder, and a controller. The polarization modifying device receives a laser beam and modifies the polarization of the laser beam. The controller, which is connected to the polarization modifying device, adjusts an input to the polarization modifying device in order to control modification of the polarization of the laser beam based on alignment of a structure to be processed by the laser beam. For example, the polarization of the laser beam may be rotated to correspond with the alignment of a link in a semiconductor device to be cut by the laser beam. The polarization modifying device is configured for incorporation into a laser processing system that produces the laser beam received by the polarization modifying device and that focuses the laser beam modified by the polarization modifying device onto a workpiece that includes the structure to be processed by the laser beam.

Abstract: Negative pressure to accelerate flashback is formed by selective deformation of an elastomeric bladder. The bladder and a next adjacent cam means are enclosed in a housing, penetrated by a slide or roller engaging the cam surface. As the slide or roller moves along the cam surface, the bladder is selectively deformed first to close, then to evacuate distally and then to reopen at a negative differential pressure.
