Abstract: An attention performance test uses a visual display, a test subject input device, a memory and a programmed processor coupled to each of the above to administer a test to a test subject. A test target, which for example can be a word colored in a first color but meaning another color, is attempted to be matched by the test subject to one of a series of sequentially presented visual response targets. In one embodiment, a nonvisual test stimulus is also provided to the test subject, the test subject having previously been instructed to respond to the nonvisual test stimulus (such as a beep) in a particular way. The test also measures the response latency of the test subject, i.e., whether the test subject has assumed a correct position for entering a response. The responses from the test subject are recorded and may be compared with data derived from a test subject database in assessing whether an attention deficit disorder exists.

Abstract: A multifunction integrated power unit (MIPU) for use aboard aircraft provides the functions both of an auxiliary power unit and of an emergency power unit while being smaller, lighter, and less expensive than the two units it replaces. Additionally, the integration of both functions in a single unit allows elimination of duplicated service devices and a further reduction in size, cost, and weight in the aircraft itself. The MIPU includes two turbine engines operable under differing conditions, an integrating gear box receiving power from the two engines selectively, and a plurality of accessory devices receiving shaft power from either of the two engines via the gear box.
