Bone length adjustment method and system includes a two-part telescopic device connected to bone parts whose length between the connection points is to be adjusted, with each part of the telescopic device being secured to the bone part, and a rod with an embedded permanent magnet which is in threaded engagement at one or both of its ends with one or both of the parts of the telescopic device. The permanent magnet in the rod is excited by an external solenoid arrangement to cause a radial force to develop at the rod thereby causing it to rotate. Rotation of the rod is converted via the threads at one or both of its ends to axial motion or movement of the telescopic parts relative to each other and thereby causes an increase or decrease in the bone length depending on the direction of axial movement between the telescopic parts.

A mirror or other reflecting surface is used for collecting and reflecting incident solar radiation. The mirror is supported for independent motion about a pair of axes. An accelerometer generates signals representative of an amount and direction of motion of the mirror about each of the axes. Motors or other drive mechanisms independently drive the mirror about each of the axes. A tracking device provides information about the current position of the Sun. A control is connected to the accelerometer, the motors and the tracking device for maintaining a predetermined optimum orientation of the mirror as the Sun moves across the sky. Position sensors that sense the position of the mirror relative to the earth's magnetic field may also be employed.

Whether or not an angular velocity detected by an angular velocity sensor is used for a game process is determined, and a difficulty level of a game to be subjected to a game process is set so as to vary depending on whether the angular velocity is determined to be used or the angular velocity is determined not to be used. When the angular velocity is determined not to be used, a process of specifying a motion direction of an input device is performed by using acceleration detected by an acceleration sensor, whereas when the angular velocity is determined to be used, at least a part of the process of specifying the motion of the input device is performed by using the angular velocity detected by the angular velocity sensor. Accordingly, based on the specified motion direction, the game process is performed while the set difficulty level is applied.

Movement through multi-dimensional space is simulated using a series of panoramic images which are projected or displayed in sequence. The user's direction of view, that is the selected view window, is maintained as the series of images is projected or displayed. Motion in directions other than forward or reverse is simulated by utilizing "branch" points in the sequence. Each path from a branch point simulates motion in a different direction. Branch points are generally indicated to a viewer by visual indicators called "hot spots"; however, branch points may also be hidden and activated in response to the viewer's selected direction of view. If a branch point is indicated by a visual indicator, a user can select motion in a desired direction by clicking on a "hot spot". In order to conserve storage space, the image representing each panorama can be stored in a compressed format. Only the portion of the panorama necessary to create a "view window" that is, the portion of the image displayed in response to the user's direction of view, is decompressed at view time. An index methodology is used to store the panoramic images. Use of the indexing methodology allows the images to be retrieved in both the forward and backward direction to simulate movement in either direction. Sound is provided in a special format, so that special effects can be provided based on the user's point of view and dependent upon the direction of motion selected by the user.
