    • A radiotelephone includes a multifunctional headset that operates in two different modes. According to a first mode, the headset may be mounted on a radiotelephone body where it serves as a speaker and microphone for the radiotelephone. Also, the headset can be separated from the body of the portable radiotelephone and placed on the head of the user. In this mode of operation, the headset receives and transmits signals from and to the radiotelephone body during a call, thus providing hands-free operation. The headset can be attached to a user's head by an ear clip. The headset and body may include low power RF transceivers. The headset may contain power saving circuitry to minimize power drain from an internal battery. The battery may be recharged whenever the headset is fixed to the radiotelephone.
    • 无线电话包括以两种不同模式操作的多功能耳机。 根据第一模式,耳机可以安装在无线电话机主体上,其中它用作无线电话机的扬声器和麦克风。 此外,耳机可以与便携式无线电话机的主体分离并放置在用户的头上。 在这种操作模式中,头戴式耳机在通话期间从无线电话机主体接收和发送信号,从而提供免提操作。 耳机可以通过耳夹连接到用户的头部。 耳机和主体可以包括低功率RF收发器。 耳机可能包含节电电路,以最大限度地减少内部电池的功耗。 只要耳机固定在无线电话机上,电池就可以进行充电。

    • An approach to managing stored-value data objects, such as electronic tickets, comprises secure systems and procedures for ticket issuing, storage, and redemption. With these systems and procedures in place, stored-value data objects may be securely transferred to remote systems, such as a user's personal electronic device, for subsequent secure redemption, thus allowing the user to gain access to the desired goods or service upon redeeming the data object. Techniques provide secure delivery of the requested data object to the requesting device, and provide secure redemption and disposal of the data object. Ticket issuing systems may be Internet-accessible systems, and users may purchase and redeem tickets using mobile terminals or other devices adapted for wireless communication. Standardized WPKI and Internet access procedures may be employed in ticket issuance and redemption. Techniques further provide temporary and rapid verification data objects useful where rapid ticket verification is essential, such as mass transit systems.
    • 管理存储值数据对象(例如电子票据)的方法包括用于发票,存储和兑换的安全系统和程序。 利用这些系统和程序,存储值数据对象可以被安全地传送到诸如用户的个人电子设备的远程系统,以便随后的安全兑换,从而允许用户在兑换所需的商品或服务时获得所需的商品或服务 数据对象。 技术提供所请求的数据对象到请求设备的安全传递,并且提供对数据对象的安全的兑换和处置。 票务发放系统可以是互联网可访问的系统,用户可以使用适用于无线通信的移动终端或其他设备购买和兑换票据。 标准化WPKI和互联网接入程序可用于发票和兑换。 技术进一步提供临时和快速的验证数据对象,其中快速验证是必不可少的,例如大众运输系统。
