    • A computer system provides a unified password prompt for accepting a user power-on password or an administrator password. A password string entered by the system administrator at the unified password prompt is compared with a stored power-on password. If the user password string matches the stored power-on password, then access to system resources is granted. If the user password string does not match the stored power-on password, then the user password string is compared to a stored administrator password. If the user password string matches the stored administrative password, then access to system resources is granted. If the user password string does not match the stored administrative password, then the system administrator is given a predetermined number of times to enter a password string matching either the stored power-on password or the stored administrator password. If a password string matching either the stored power-on password or the stored administrator password is not provided in the predetermined number of times, access to system resources is denied. The unified password prompt does not require a system administrator to know a user's power-on password in order to access system resources. The unified password prompt also permits a system administrator to configure a plurality of computer systems by providing a single administrative password rather than a plurality of user power-on passwords.
    • 计算机系统提供用于接受用户开机密码或管理员密码的统一密码提示。 系统管理员在统一密码提示符下输入的密码字符串与存储的开机密码进行比较。 如果用户密码字符串与存储的开机密码匹配,则授予对系统资源的访问权限。 如果用户密码字符串与存储的开机密码不匹配,则将用户密码字符串与存储的管理员密码进行比较。 如果用户密码字符串与存储的管理密码匹配,则授予对系统资源的访问权限。 如果用户密码字符串与存储的管理密码不匹配,则给予系统管理员预定次数,以输入与存储的开机密码或存储的管理员密码相匹配的密码字符串。 如果在预定次数中没有提供与存储的开机密码或存储的管理员密码相匹配的密码字符串,则拒绝对系统资源的访问。 统一密码提示不要求系统管理员知道用户的开机密码才能访问系统资源。 统一密码提示还允许系统管理员通过提供单个管理密码而不是多个用户开机密码来配置多个计算机系统。

    • Embodiments of the present invention disclose a system and method for remote touch detection. According to one embodiment, an infrared light source is projected across a front surface of a display via at least one light emitting device. Furthermore, an infrared signal is transmitted in a direction of the front surface of the display via a remote pointing device. A surface target position is then determined based on measurement data caused by disruption of a portion of the infrared light source of the light emitting device by either the infrared signal or a physical touch from a user.
    • 本发明的实施例公开了一种用于远程触摸检测的系统和方法。 根据一个实施例,红外光源经由至少一个发光器件横跨显示器的前表面投影。 此外,通过远程指示装置在显示器的前表面的方向上发送红外信号。 然后基于由来自用户的红外信号或物理触摸而使发光器件的红外光源的一部分的中断而引起的测量数据来确定表面目标位置。
