摘要： Systems and methods for automatically disabling the TCAS Broadcast when aircraft join up in formation. A Traffic Collision Avoidance System (TCAS) determines if the aircraft is approaching formation flight with other aircraft or flying in formation with other aircraft and disables a TCAS interrogation signal if the aircraft is determined to be approaching a formation or flying in formation. The TCAS receives TCAS interrogation signals from one or more other aircraft and receives aircraft configuration information from one or more other aircraft systems. The TCAS determines the aircraft is approaching formation flight or flying in formation based on the received TCAS interrogation signals, a mode of TCAS operation, and/or the received aircraft configuration information. The TCAS also automatically switches into Traffic Advisory Only mode if the aircraft is determined to be approaching formation flight or flying in formation.

摘要： An integrated circuit controls the low level, electromechanical functionality of a computer mass storage device, such as a magnetic disk drive incorporating a spindle motor for rotatably controlling a disk and an actuator for positioning at least one read/write head with respect to the disk, to read or write encoded data configured in information data sectors and to sense encoded data of servo data sectors. A servo subsystem is coupled to an output of the read/write head for detecting the servo data sectors and providing a control signal in response thereto. An analog-to-digital subsystem is also coupled to an output of the read/write head and is operative in response to the servo subsystem control signal for converting the encoded data of the servo data sectors to digital transducer position information representative of a position of the read/write head with respect to the data tracks. A data processing subsystem is coupled to the analog-to-digital subsystem for processing the digital transducer position information and providing digital motion control signals in response thereto. A digital-to-analog subsystem is coupled to the data processing subsystem for providing analog control signals to the spindle motor and the actuator in response to the digital motion control signals.

摘要： The present invention provides a method for efficient use of the transmit power of a Traffic Alert Collision Avoidance System (TCAS) that allows enhanced surveillance range and limits radio frequency (RF) interference in crowded airspace. The method reduces power density in crowded airspace by modifying Mode S, Mode A and Mode C interrogations. During Mode S broadcasts, tracking interrogation power is reduced as a function of range. Further transmit power reduction is achieved by broadcasting a variable power density whisper-shout interrogation technique for Mode A/C aircraft when garbling is detected. If garbling is observed during a medium whisper-shout interrogation sequence, the method of the present invention attempts to clear the garbling by using focused high-density whisper-shout steps but only in the ranges where garbling was detected. Formation members can account for other formation members that are TCAS equipped using a special E-TCAS Broadcast Interrogation. The presence of other E-TCAS will be used in the RF interference limiting calculations. Aircraft flying in formation further minimize broadcast power by sharing information between the formation leader and formation aircraft.
摘要翻译：本发明提供了一种有效利用交通警报冲突避免系统（TCAS）的发射功率的方法，其允许增强的监视范围并限制拥挤的空域中的射频（RF）干扰。该方法通过修改模式S，模式A和模式C询问来降低拥挤空域的功率密度。在模式S广播期间，跟踪询问功率作为范围的函数减小。当检测到乱码时，通过广播用于模式A / C飞机的可变功率密度耳语询问技术来实现进一步的发射功率降低。如果在中等耳语询问序列期间观察到乱码，则本发明的方法尝试通过使用聚焦的高密度耳语步骤来清除乱码，但是仅在检测到乱码的范围内。组成员可以考虑使用特殊的E-TCAS广播讯问装备TCAS的其他组织成员。其他E-TCAS的存在将用于RF干扰限制计算。飞机飞行通过在地层导弹和地面飞机之间共享信息进一步最小化广播能力。

摘要： A synchronous read channel is disclosed which samples an analog read signal from a magnetic read head positioned over a magnetic disk medium, filters the sample values according to a desired partial response, extracts timing information from the filtered sample values, and detects an estimated data sequence from the filtered sample values using a trellis type sequence detector matched to the partial response. The trellis sequence detector comprises programmable detector levels which allows for maximum flexibility in matching the sequence detector to the partial response.

摘要： A servo system controller for a disk drive device which includes a rotating mass storage disk incorporates a timing error determining circuit for determining rotational speed variations in the disk from information contained in a servo field recorded in a track. A timing error signal is supplied when the speed variation exceeds a threshold, thus indicating an unacceptable level of speed variation. A digital synchronizer responds to asynchronous servo data signals from the disk to establish a cell clock signal occurring about a normal frequency, a cell during which only one servo data signal will occur, and a cell data signal which occurs during the cell. The cell clock signal clocks logical operations on a synchronous basis, and servo data signals are reliably captured. A concurrence determining circuit determines the degree of concurrence between the predetermined series of cell data signals and an actual pattern of signals derived from the servo field, and recognizes the servo control information from less than complete concurrence of the derived pattern and the actual expected pattern. Normal operation is permitted even through slight inconsistences may be detected, improving data throughput while still achieving an adequate level of error tolerance.
