    • In a noisy environment, e.g., a car traveling down the road with the radio playing, a user who prefers that his pager provide him with an audible alert in response to an actuation of the pager may not be able to hear such an audible alert supplied by the pager. To overcome this difficulty, a pager that is set to an audible alert mode is arranged to change its alerting for a particular actuation of the pager from audible to tactile only when the ambient sound level of the environment in which the pager is located is greater than a predetermined threshold level. For each actuation of the pager that the ambient sound level in the environment in which the pager is located is less than the predetermined threshold level, the pager alerts audibly. Optionally, if the pager also determines that it is no longer being worn on the person of a user, the pager alerts audibly regardless of whether the ambient sound level is greater than the predetermined threshold level. Advantageously, as much of the time as feasible the user receives only the type of alert he desires, namely audible, while receiving the alternative form of alert, namely tactile, only when necessary to avoid loss of the page by the failure of the use to perceive the alert.
    • 在嘈杂的环境中,例如,通过无线电播放在汽车上行驶的汽车,喜欢他的寻呼机响应于寻呼机的致动向他提供可听警报的用户可能不能听到提供的这种可听到的警报 由寻呼机。 为了克服这个困难,设置为可听警报模式的寻呼机被布置成仅当寻呼机所在的环境的环境声级大于大于的情况时,才能将寻呼机的特定致动器的警报改变为可听到触觉 预定的阈值水平。 对于寻呼机的每个致动,寻呼机所在的环境中的环境声级都小于预定阈值水平,寻呼机可听到警报。 可选地,如果寻呼机还确定其不再佩戴在用户的人身上,则无论环境声级是否大于预定阈值级别,寻呼机都可以听到警报。 有利的是,尽可能多的时间,用户仅接收到他所期望的类型的警报,即可听见的,同时接收到替代形式的警报,即触觉,仅在必要时避免由于使用失败而丢失页面 察觉到警报。

    • With the advent of personal digital assistants (PDAs) having modems for information, e.g., facsimile and/or data, transmission over wireless connections, as well as the capability for voice communications, we have recognized that is possible to communicate with a person, wherever they are, in whatever form is desired. In order to do so in a manner that simulates the way a person at a fixed location having a separate telephone, fax machine and data modem would communicate, incorporate into a PDA is a) a receiver for a wireless actuation signal that indicates that a communication of some type is waiting for a called party; b) an outgoing connection origination unit that establishes a connection from the PDA to the waiting communication; c) a discriminator, which makes a determination as to the type of communication that is waiting; and d) a selection unit that routes the information signals received over the connection established by the PDA to an appropriate communication unit within the PDA, e.g., a fax modem, data modem, or voice communication unit, the appropriate communication unit being selected in response to the type of communication that was determined by the discriminator to be waiting. The PDA owner may optionally be alerted only when 1) an information transmission is successfully completed and the received information is waiting in the PDA for access by its owner, or 2) when a voice connection has successfully been established to the communication originator who continues to indicate a readiness to communicate.
    • 随着具有调制解调器的个人数字助理(PDA)的出现,例如传真和/或数据,通过无线连接的传输以及语音通信的能力,我们已经认识到可以与人通信,无论在哪里 他们是,无论什么形式的需要。 为了这样做,以模拟在具有单独的电话,传真机和数据调制解调器的固定位置处的人的通信方式,并入PDA中的是:a)用于指示通信的无线致动信号的接收器 某种类型的人正在等待一个被叫方; b)建立从PDA到等待通信的连接的出站连接发起单元; c)歧视者,对正在等待的通信类型作出决定; 以及d)选择单元,其将通过PDA建立的连接接收的信息信号路由到PDA内的适当的通信单元,例如传真调制解调器,数据调制解调器或语音通信单元,响应于选择的适当的通信单元 由鉴别器确定的要等待的通信类型。 只有当1)信息传输成功完成并且所接收的信息在PDA中等待其所有者访问时,PDA所有者可以可选地被警告,或者2)当语音连接已经成功建立到继续进行的通信发起者时 表示准备沟通。
