Abstract: Methods and apparatus, including computer program products, implementing and using techniques for an integrated user interface an interface that receives user input through the user interface. User selection input received through the user interface is used to sequentially update a selection register and sequential user selections are differentiated within the user interface based on their status within the selection register.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for an integrated user interface an interface that receives user input through the user interface. Output is provided through the user interface, and all user input received through the user interface is interpreted as explicitly being separated input into one of three classes, namely, pointing input, content input, and command input.

Abstract: Disclosed is an input device for a portable terminal. The input device includes a transparent keypad which is provided on a rear side thereof with input sections of a plurality of keys, and an input signal processing unit for generating an input signal corresponding to the key selected by a user from among the plurality of keys and processing the generated signal. A portable terminal with such a input device further includes a display unit for displaying a result of input signal processing in the input signal processing unit.

Abstract: A method and apparatus for controlling a keyboard operated device having a plurality of keys includes a plurality of sensors associated with each key. Each sensor detects a different one or more attribute of the nature of actuation of the key. Each detected attribute is used by selection circuitry to form a characteristic of the device's response to actuation of the key. The individual characteristics are combined to form a response to actuation of the key. The response may be an output signal or may be further processed internally by the device. In a preferred embodiment the invention is part of a musical synthesizer. One sensor is arranged to detect actuation of a key, while a second sensor is arranged to detect which finger actuates the key. The detection of actuation of a key is used to control the pitch of the resulting output. The detection of which finger actuates the key is used to control the timbre of the resulting output signal.

Abstract: A method and apparatus are disclosed for controlling an electronic display using a keyboard to allow designation of desired regions on the display or in the memory of the system. A method of designating desired regions on the display under control of a keyboard which has at least one designation key includes the steps of positioning a cursor at a first location in fixed relationship to the desired region, activating a first designation key, and supplying through the keyboard signals to indicate a second location in fixed relationship to the selected region to cause a portion of the selected region between the first location and the desired location to be designated.

Abstract: A system for creating and modifying strings of symbols in a computer storage apparatus includes a two-part cursor for guiding the operator. One cursor part indicates the exact location where entered symbols will be inserted. A second cursor part highlights a selected substring which is the object of certain commands, such as the delete command. Internally, the system provides memory management techniques for inserting and deleting symbols in response to operator commands. The display, including the two-part cursor, is derived from the memory contents with the aid of pointers, tables, and state variables.

Abstract: A digital electronic tuning device is provided in which an arrangement of light-emitting diodes [LED's] or other display elements indicates when two frequencies are equal. If the frequencies are unequal, the device provides an indication of both the magnitude and direction of the inequality. For use as a tuner of musical instruments, one frequency is provided by a preset clock while the second frequency derives from the musical instrument under test. In operation, a circular pattern of lights on the display elements appears stationary when the instrument is in tune and appears to rotate or spin when the instrument is out of tune. Some information about the harmonic content of the frequency of the signal under test may also be read from the device. In one embodiment, the invention may be used in connection with a stepping motor to automatically tune an instrument.

Abstract: An electronic component is provided having mounting leads configured as concentric arcs centered about a desired axis of rotation. The leads may therefore be inserted into a mounting board, and the component rotated to a desired angle with respect to the surface of the mounting board. In some embodiments, one or more of the mounting leads is provided with tabs or other positioning elements to facilitate the positioning of the component at any of a number of selected angles relative to the mounting board.

Abstract: A model aircraft is constructed from a material having a plurality of parallel channels therein, e.g., corrugated cardboard. The aircraft is formed so that all of the various side, top, and bottom panels are gently curved over the length of the fuselage to provide a stressed fuselage which is aerodynamically sound, attractive, and extremely strong. A pair of wings are constructed so that each wing has span-wise corrugations along which bends or folds are made to produce an airfoil, e.g., by conforming to the shape of a number of ribs which define the airfoil shape. Dihedral of the wings is provided by a number of spring-like elements such as wires which can be bent and inserted into corrugations in the wings to join the wings at the required dihedral angle while allowing span-wise flexibility of the wings. The wings may be inserted into slots in the fuselage and rest upon a wing saddle therein. In accordance with different embodiments of the invention, alternate wing structures are provided.
