Abstract: 1. Method for entering switching-related customer and operational data into communication exchanges and/or programmable communication terminals. 2.1 The operating and preparatory procedures involved in the entering of switching-related customer and operational data into communication exchanges and/or programmable communication terminals are to be simplified and shortened. The preparatory work and space required for connection cables and connection plugs for entries of this type are to be avoided, and unified entry conditions are to be created for a multiplicity of exchange and terminal types. 2.2 For entering the data required for the operation of a communication exchange or a communication terminal, a uniformly designed remote control device is used, which is directed towards a wireless receiver fitted to the housing of the exchange or of a terminal. Once a system-independent unified entry procedure has been carried out, the switching-related data are transferred from the remote control device to the exchange or to the terminal. Here, the data are transformed so that they can be stored, in a form appropriate to the system, in a memory provided for this purpose. Along with a dialling keypad and function keys for individual entries, the remote control device also contains a reading device to hold an input storage medium, with which substantial amounts of data can be entered by wireless means. The remote control device also has a receiver, with which signals can be transmitted from the exchange to the remote control device, which signals can be shown on a display device. Furthermore, operational data can be retrieved via the remote control device from an exchange or from a terminal. 2.3 With the uniformly designed remote control device and through uniform operating procedures, a wide variety of communication exchange or terminal types can be operated in identical fashion with no need for extensive preparations. <IMAGE>

Abstract: At the transmit end of a communications system, a convolutional code of a multiplex of an information-bearing signal and a unique word is modulated upon a transmitted carrier. At the receive end, the transmitted carrier is demodulated with a local carrier to detect the convolutional code. The error rate of a decoded version of the convolutional code is determined, and an out-of-FEC-sync signal is produced when the error rate is higher than a threshold value. Unique words are detected from the decoded signal and counted during a prescribed time interval to produce an out-of-frame-sync signal when the count falls below a threshold. The frequency of the local carrier is swept in the presence of the out-of-FEC-sync signal. When this signal ceases to exist, a timeout period is set, and the local carrier frequency is swept again when the timeout period expires during the presence of the out-of-frame-sync signal.

Abstract: A plurality of node apparatuses are connected by an optical transmission line. Each of the node apparatuses is assigned with a wavelength as an address different from the others. Therefore, when a first node apparatus transmits data to a second node apparatus, the data is of a wavelength corresponding to the address of the second node apparatus. The data transmission is carried out in a time slot defined by a frame pulse. The data of the corresponding wavelength is only received in the second node apparatus, and data of other wavelengths are passed through the second node apparatus. Consequently, media-access control is easily carried out independently in each node apparatus in an optical network system by using wavelength division multiplexing.

Abstract: An efficient buffering mechanism for access and retrieval of stored high bandwidth data and sufficient storage is disclosed. In a typical operating system, a channel containing only a limited buffer between the input devices and the running applications is provided by the operating system. This invention provides a parallel channel of a higher bandwidth with a far superior buffering capability that complements that of the operating system. When an input event from an input device with a high bandwidth is received by the system, messages are sent to both the operating system channel and the high bandwidth channel in a compatible format for each channel. The message sent to the operating system channel generally contains only limited data which may have to be translated from the actual input data to be acceptable to the operating system. The message sent to the high bandwidth channel contains the full spectrum of data generated by the input device. The buffer in the operating system channel also has the property of discarding data if the application does not retrieve them quickly enough during periods of high CPU utilization. The buffer in the high bandwidth channel keeps all data for up to 1000 input events, or whatever is deemed sufficient for the computer system, regardless of CPU usage. 
     In response to the interception of a translated event in the operating system queue for one of the applications in the system, the method of the present invention will check to see if there are any events in the high bandwidth buffer. If there are, the system dequeues all the events to send them to the intended application. Various flags are set if task preemption is detected by the system upon examination of the events in the high bandwidth queue. Further, certain events may be sent asynchronously to the high bandwidth channel alone from various input devices; the system is prompted by a false "mouse" message in the operating system queue to cause the system to examine the high bandwidth buffer for the true input event.

Abstract: When sampling light and light to be measured each having a wavelength longer than an upper wavelength limit of the sensitivity of a photocathode are incident on the photocathode of a multiphoton absorption-type electron tube, light-light sampling is enabled by two-photon absorption and one-photoelectron emission. A delaying unit (6) adjusts an incident timing of the sampling light from an optical pulse generating unit (4) on the electron tube (2) in synchronism with an incident timing of the light to be measured on the electron tube. A half mirror (8) causes the sampling light and the light to be measured to coincide on the photocathode of the electron tube (2). A controlling unit (12) controls the delaying unit to sequentially shift the incident timing of the sampling light on the electron tube. Thus, the operation of a display unit (10) can be controlled in synchronism with the incident timing of the sampling light so that a series of sampling outputs from the electron tube can be converted to the optical waveform of the light to be measured and displayed on the display unit.

Abstract: An image coding/decoding apparatus intended for efficient processing by sharing members in coding, local decoding, and decoding processing. Processes such as DCT and IDCT, zigzag scan conversion and inversion, or quantization and inverse quantization performed in coding, local decoding, and decoding processing are similar to each other. DCT/IDCT, zigzag scan conversion/inversion, and quantization/inverse quantization are provided where either of the two functions can be selected for execution in synchronization with the processing timing for each block. Since the time required for one process for data for each block is very short, overall processing is not affected even if the members are used in a time division manner. By sharing processing, the hardware scale can be made small and by using a data bus in a time division manner, an external data bus can also be eliminated.
