    • A method and system for providing diagonal scrolling on a touchpad of a device is disclosed. The method and system comprises determining if at least one finger is in contact with the touchpad, and entering a diagonal scroll mode if more than one finger is in contact with the touchpad. A system and method in accordance with the present invention allows the user to initiate a diagonal scroll at any location on a touchpad by using two fingers, thereby greatly enhancing the functions of the touchpad and allowing the user to manipulate computer programs from the touchpad much more efficiently and easily. The present invention supports diagonal scrolling on a touchpad and does not require a precise location for vertical or horizontal scrolling, since the entire touchpad area/surface can be used. The system and method in accordance with the present invention will also operate correctly on existing touchpads when a change in software drivers has been carried out.
    • 公开了一种用于在设备的触摸板上提供对角滚动的方法和系统。 该方法和系统包括确定至少一个手指是否与触摸板接触,以及如果多于一个手指与触摸板接触,则进入对角线滚动模式。 根据本发明的系统和方法允许用户通过使用两个手指在触摸板上的任何位置处发起斜向滚动,从而大大增强了触摸板的功能,并允许用户从触摸板操纵更多的计算机程序 有效和容易地 本发明支持触摸板上的对角滚动,并且不需要垂直或水平滚动的精确位置,因为可以使用整个触摸板区域/表面。 当已经执行了软件驱动程序的改变时,根据本发明的系统和方法也将在现有的触摸板上正确地操作。

    • A security system for computers defines a control zone using radiation, preferably at radio frequency, having a distinctive characteristic, such as a particular frequency. The zone may be established, for example, at a door exit or other limited passage to a secured area. The radiation triggers a device in the computer that in turn sends out a serial number signal. To further prevent unauthorized removal a personal identification number is required of the person in the zone with the computer, either by key input or an encoded radio signal. A receiver located near the control zone applies the serial number to a table look up computer that triggers an emergency signal if a match to an authorized list of serial numbers for the computer and corresponding person does not occur. The emergency signal activates a transmitter that sends out an emergency radiation signal with a different distinctive characteristic. A second receiver in the computer then responds to the emergency radiation signal to trigger the security logic to render the computer inoperative.
    • 用于计算机的安全系统定义了使用辐射的控制区,优选地在射频下具有特征,例如特定频率。 该区域可以例如在门出口或其他有限通道建立到安全区域。 辐射触发了计算机中的一个设备,它依次发出序列号信号。 为了进一步防止未经授权的移除,可以通过键盘输入或编码的无线电信号,通过计算机对该区域中的人员进行个人识别号码。 位于控制区附近的接收器将序列号应用于表查找计算机,如果与计算机和相应人员的相应人员的序列号的授权列表不匹配,则触发紧急信号。 紧急信号激活发送具有不同特征的紧急辐射信号的发射机。 然后,计算机中的第二个接收器响应于紧急辐射信号,触发安全逻辑使计算机无效。
