Abstract: A bird deterrent device is presented having a base that is at least partially composed of a metal or metal composite. The base can be configured such that the base has sufficient resiliency to revert to an original form after being bent at least 15°. A plurality of spikes can be coupled to the base so that the device is stackable with other such devices while the spikes are oriented at least 5° out of parallel with respect to a plane of the base. It is contemplated that the devices can be stacked such that the base of one device is less than 3 cm from the base of an adjacent device in the stack.

Abstract: A centralized control unit directs compressed air towards repellant dispensers in different repellant locations to distribute atomized bird repellant. The control unit can contain a timer module that controls the time, duration, and recurrence of the mist pulses to optimize bird repellant use. Multiple bird repellant storage tanks can be placed in each repellant dispenser, or a single, common bird repellant storage tank can be used to deliver bird repellant to each repellant dispenser.

Abstract: An apparatus for accelerated weathering testing specimens including discharge lamps as a concentrated light source for accelerating the deterioration of color, composition and/or structure of test specimens. Improved control calibration structures and methods of operation are also included. The test module to monitor the weathering test process from an improved location, detecting irradiance in the manner in which the specimens are exposed to such irradiance. The test modules are mounted in a pocket formed within the door for the test chamber such that the sensitive electronics of the modules are not exposed to the harsh environment within the test chamber, resulting in an exceptionally stable signal.
