    • A handheld wireless communication device configured to send and receive text messages. The device is hand cradleable with a body configured to be held in one hand by an operator during text entry. A display is located on a front face of the body and upon which information is displayed to the operator during text entry. A key field is also located on the front face of the body and that includes a plurality of alphanumeric input keys and menu control keys. A trackball navigation tool is located on the front face of the body. The keys have a primary engagement surface for receiving an operator's touch engagement and a chamfer surface descending down from the primary engagement surface such that the chamfer surface defines a finger clearance space. A microprocessor is provided that receives operator commands from the keys and the trackball navigation tool and which affects corresponding changes to the display based on user input.
    • 被配置为发送和接收文本消息的手持无线通信设备。 该装置是可手握的,其中主体被配置为在文本输入期间由操作者一只手握持。 显示器位于身体的正面,并且在文本输入期间向显示器显示信息。 关键字段也位于身体的正面,并且包括多个字母数字输入键和菜单控制键。 轨迹球导航工具位于身体的正面。 键具有用于接收操作者的触摸接合的主接合表面和从主接合表面向下降低的倒角表面,使得倒角表面限定手指间隙空间。 提供了一种微处理器,其从键和轨迹球导航工具接收操作员命令,并且基于用户输入影响对显示的相应变化。

    • A segmented furrow closing wheel comprises a body member rotatable about a rotation axis. The body member comprises a hub and a plurality of fingers radiating from the hub. Each of the fingers has a root end connected to the hub, and each of the fingers terminate at a radially outermost end with a contact surface for contacting a contact patchy on the ground surface. The contact surface of one of the fingers being spaced from the contact surfaces of the adjacent fingers of the plurality of fingers. The contact surface is blunt in character.
    • 分段沟槽闭合轮包括可围绕旋转轴线旋转的主体部件。 主体构件包括轮毂和从轮毂辐射的多个指状物。 每个指状物的根端连接到轮毂,并且每个指状物在径向最外端处终止,其具有用于接触地面上的接触片的接触表面。 一个指状物的接触表面与多个指状物的相邻指状物的接触表面间隔开。 接触面是钝的。
