摘要： A keyboard for use with a computer is disclosed. The keyboard has an array of keys made up of four rows such that all keys are accessible by a user using finger and thumb movements of the user's hands without moving the hands from a central location. All modes and functions of the keyboard are accessible using finger movements also in that the character keys on the keyboards are capable of producing different characters or performing different functions when actuated in combination with other mode and function keys on the keyboard. The keyboard has a space bar and an enter key that are accessible by the user's thumbs. The space bar and enter key are actuated by pressing either key horizontally rather than vertically as in standard keyboards. The keyboard also includes dual mode keys which allow the user to access additional modes. This feature expands the capability of the keyboard to interact with more software functions. The keyboard also includes a trackball that is accessible using either of the user's thumbs with its three buttons accessible by the index finger of either hand. The front surface of the trackball lies in a plane perpendicular to the plane of the keyboard. The keyboard also includes visual aids on each key so that the user can correlate a given mode with the function it produces when used in conjunction with a multiple character function key. The keyboard also includes an accessory platform extending from below the array of keys and towards the user. The accessory platform can accommodate an electronic notepad and audio speakers. The keyboard also includes a detachable antenna that can be mounted on the keyboard for use or stored within the keyboard when not in use. The keyboard also includes a microphone mounted within the keyboard.

摘要翻译： 公开了一种用于计算机的键盘。 键盘具有由四行组成的键阵列，使得用户可以使用用户的手的手指和拇指移动而无需从中央位置移动手指即可使用所有键。 键盘的所有模式和功能都可以使用手指移动进行访问，而且键盘上的字符键可以与键盘上的其他模式和功能键一起启动时产生不同的字符或执行不同的功能。 键盘具有可由用户的拇指访问的空格键和输入键。 空格键和进入键通过按压水平方向而不是垂直方向按照标准键盘来启动。 键盘还包括允许用户访问附加模式的双模式键。 此功能扩展了键盘与更多软件功能交互的功能。 该键盘还包括一个轨迹球，使用任一用户的拇指，其三个按钮可由任一只手的食指接触。 轨迹球的前表面位于垂直于键盘平面的平面内。 键盘还包括每个键上的视觉辅助功能，以便用户可以将给定模式与其与多个字符功能键结合使用时所产生的功能相关联。 键盘还包括从键阵列下方向用户方向延伸的附件平台。 附件平台可容纳电子记事本和音频扬声器。 键盘还包括可拆卸的天线，其可以安装在键盘上以供使用或存储在不使用的键盘内。 键盘还包括安装在键盘内的麦克风。

摘要： An anti ship warhead utilizing a reactive case is disclosed. The case is aagnesium alloy which increases the blast damage once the warhead moves into the interior of a target. Moreover, the nose plate is hardened steel specially designed to cause ripping and tearing of the exterior wall as the warhead penetrates.
