Abstract: A method monitors radiation incidence onto an object being prepared for and/or undergoing radiation delivery. The monitoring method includes: emitting a light field onto a surface of an object being prepared for and/or undergoing radiation delivery, the light field at least substantially corresponding to radiation incidence of the radiation delivery; monitoring the light field being reflected from the surface of the object; and processing the monitored light field to determine the radiation incidence of the radiation delivery relative to the object at least partially based on the monitored light field.

Abstract: A basketball system having a basketball goal and a lighting system such that light is provided for the playing of basketball or other activities at night. The lighting system has a lighting apparatus and a pole with a vertical shaft and an arm. The lighting system is configured to couple to an existing basketball goal or be installed remote to the basketball goal. The lighting apparatus is configured to be lowered near to the ground by rotating the lighting system such that servicing may be done to the lighting apparatus without the use of a ladder.

Abstract: An optical system includes a laser diode, a collimating lens and first and second housing parts. The first housing part retains the collimating lens therein. The second housing part engages the first housing part to retain the laser diode therebetween. The position of the laser diode is adjustable with respect to the collimating lens in X, Y and Z directions. One or more biasing members are interdisposed between the housing parts in the X direction, the Y direction, and/or the Z direction for biasing the laser diode relative to the collimating lens in the X direction, the Y direction and/or the Z direction. One or more securing members fixedly engage the first and second housing to one another and provide a compression force on the housing parts to maintain the relative position of the laser diode with respect to the collimating lens in the X, Y and Z directions.

Abstract: A pressurized squeeze casting apparatus and method for casting articles includes densifying means for mechanically applying force to a die assembly to compress and densify the molten metal material into a solid article having a near net shape. A shutoff member is provided to seal the interior cavity at the juncture of the runner and the cavity after the cavity is filled with molten metallic material and prior to densification. A low pressure furnace provides a supply of molten metallic material. The outlet from the furnace is biased into engagement with the runner by the gas pressure in the low pressure furnace to ensure a fluid tight connection between the furnace and the runner.
