Abstract: A method of operating an air traffic control system may include receiving, by a control system, an instruction from a control system user. The method may further include providing, by the control system, the instruction to an airplane via a data link between the control system and a system of the airplane. In addition, the method may include adjusting, by the airplane system, at least one airplane control to correspond to the instruction.

Abstract: A method of receiving an instruction by an airplane from a control system includes facilitating, by the airplane, a user of a system of the airplane in accepting or rejecting the instruction. The instruction may be received by the airplane via a data link between the control system and the airplane system. If the instruction is accepted, the method may further include loading, by the airplane, the instruction into the airplane system and/or adjusting, by the airplane, at least one airplane control to correspond to the instruction.

Abstract: Methods and apparatuses for receiving, by an airplane, one or more clearances and/or instructions from a control system via a data link between the control system and a system of the airplane, are described herein. The system of the airplane may then facilitate a user in accepting or rejecting at least one of the received one or more clearances and/or instructions, and if accepted, may load the clearance and/or instructions and/or adjust controls to correspond to the clearance and/or instructions. Further, the system of the airplane may be adapted to display at least instructions indicia of whether the received instructions are met to a user.

Abstract: The invention discloses differing embodiments of methods, aircraft, and apparatus for communicating the braking conditions of a runway. In one embodiment, braking information may be determined from a first aircraft which has landed on the runway. The braking information may be communicated to air traffic control and/or a second aircraft. Communication of the braking information may take place utilizing an Automatic Dependent Surveillance Broadcast system (ADS-B) and/or other type of automatic networking system.

Abstract: The invention discloses differing embodiments of methods, aircraft, and apparatus for determining the landing conditions of a runway. In one embodiment, braking data may be collected from an aircraft which has landed on the runway; a braking performance measurement of the aircraft may be calculated based on the braking data; and a normalized braking performance measurement may be determined based on the braking performance measurement. The invention may be utilized to predict the expected braking performance of various types of aircraft on the runway. The invention may provide landing performance information to a broad host of users, and/or may be used as a basis for the development of a new aviation standard for the reporting of runway braking action.

Abstract: A display system (12) for attachment to a sill (14) of a window structure (26) has been provided. The display system (12) includes a mounting device (28) for attaching the display system (12) to the sill (14) of the window structure (26) and a display device (18) for attachment to the mounting device (26). The display device (18) is intended to communicate various information to the viewer of the display device and preserve or create more available space surrounding the window structure (26).

Abstract: This invention provides an equal path length lateral shearing interferometer and its implementation in focus detection devices, particularly for optical data storage devices. The interferometer comprises a beamsplitter and two abutting roof prisms. Shifting the placement of a roof prism along an axis orthogonal to the direction of light propagation and to the peak of the roof creates a lateral shear between the two output beams. Rotation a roof prism about this axis produces a tilt between the two output beams. This creates an interference pattern with a rotational orientation which is a function of the focus of the beam impinging on the optical storage medium. A pattern sensor is provided to adjust the focus of the beam in an accurate and dynamic manner.

Abstract: An adaptor cartridge for holding a 90 mm optical disk cartridge for insertion into a 130 mm disk drive apparatus. The cartridge adaptor emulates the external dimensions and features of a 130 mm cartridge so that it can be loaded into and manipulated by the 130 mm drive in the same manner as a normal 130 mm cartridge. The cartridge adaptor contains a shutter arm for opening the 90 mm cartridge door upon insertion of the cartridge into the adaptor cartridge in much the same manner as a 90 mm cartridge door is opened when the cartridge is inserted into a 90 mm drive. The cartridge adaptor also contains a pseudo 90 mm spindle located in an adaptor hub. The pseudo spindle fits within the centering hole of the 90 mm media disk. The adaptor cartridge carries an annular magnet for attracting and holding the 90 mm media disk on the adaptor hub. The underside of the adaptor hub is a simulated 130 mm cartridge hub for mating with the 130 mm drive spindle.

Abstract: A recording/playback apparatus in which movable datum pins are held in a base casting. Upon insertion of a cartridge into a holding tray, within the apparatus, the pins are released to move into datum holes in the cartridge when the holes are positioned directly above the pins. The cartridge is then lowered onto the drive spindle and positioned on surfaces of the base casting. During the load cycle, the cartridge is allowed to move relative to the holding tray while continuing to be held in place relative to the base casting by the datum pins.
