Abstract: A lithographic apparatus has an alignment system including a radiation source configured to convert narrow-band radiation into continuous, flat and broad-band radiation. An acoustically tunable narrow pass-band filter filters the broad-band radiation into narrow-band linearly polarized radiation. The narrow-band radiation may be focused on alignment targets of a wafer so as to enable alignment of the wafer. In an embodiment, the filter is configured to modulate an intensity and wavelength of radiation produced by the radiation source and to have multiple simultaneous pass-bands. The radiation source generates radiation that has high spatial coherence and low temporal coherence.

Abstract: A retractable pin injection molding assembly includes a cartridge comprising a mold cavity, a cavity sleeve to accept water and vacuum lines at the back of the mold, an ejector assembly, and a pin connection block with a groove for a locking slide, so that the cartridge may be changed rapidly without disassembling the injection molding assembly. Also provided is a mechanism for continuously adjusting the length of the ejector pins within the mold cavity.

Abstract: The present invention describes an injection molding process for manufacturing golf balls using thermoplastic materials. The injection mold is provided with a heating source and one or more valve gates. The heating source maintains the temperature of the molten thermoplastic material in the conduits through which it is delivered to the mold cavity, and the valve gate shuts off the flow of molten thermoplastic material to the mold cavity. Advantageously, this process reduces or eliminates “trim” or waste material, and thus also minimizes the necessity to recycle thermoplastic material.

Abstract: A method of monitoring utility lines with an aircraft. A first step involves equipping the aircraft with at least one dual sensor camera capable of concurrently capturing both thermal images and real time video images. A second step involves equipping the aircraft with at least one of a storage medium adapted to store the thermal images and the video images or a display medium capable of concurrently displaying the thermal images and the video images. A third step involves flying along a utility right of way concurrently capturing the thermal images and the video images with the dual sensor camera. A fourth step involves reviewing the thermal images for thermal anomalies and the video images for visual anomalies.

Abstract: A method of aerial monitoring of forests. The method includes a step of examining a forest from above with a camera capable of capturing a thermal image. The camera has a resolution of at least 460×460 pixels. The purpose of the monitoring is to determine reflective qualities of trees in the forest, such reflective qualities being indicative of moisture content.

Abstract: An aircraft mounted video recording system includes, in combination, an aircraft and at least one video camera secured to the aircraft. A solid state storage unit is provided having a storage capacity of at least 5 gigabytes of uncompressed data. The solid state storage unit is mounted within the aircraft and receives data from the at least one video camera.
