    摘要： A method authenticates di identities in parallel using two prime numbers p and q such that q|p−1. Each identity includes a private key si and a public key vi, and a publicly known generator is α such that αq≡1 (mod p). A verifier is provided with an ordered list of the public keys vi. A prover selects uniformly at random a non-negative number r less than q. A number x=αr (mod p) is sent from the prover to a verifier. The verifier selects uniformly at random a non-negative number e less than 2(t+logd), where log is base 2, and a number t is a predetermined security parameter. The prover receives from the verifier the number e. A number y=r+Σi si*ei (mod q) is generated by the prover, and the number Y is sent to the verifier, who then determines if an equality x=αy*Πi(vi)ei (mod p) is true. The prover is accepted as having the di identities if and only if the equality is true. In a preferred embodiment the communications between the prover and the verifier is via a low-bandwidth optical channel.

    摘要： A cell phone includes illuminated components and a proximity sensor. The proximity sensor detects when the cell phone is coupled to the ear of a user. Therefore, the proximity detector is placed, in part, near the loudspeaker of the cell phone. The proximity sensor controls the illumination of the illuminated components according to the coupling. The illumination is off when coupled, an on when not coupled. The amount of illumination can depend to the intensity of ambient light as measured by a photodiode.

    摘要： Touch screen interfaces suffer from a visual-motor conflict when the user attempt to interact with a virtual object but experiences no physical sensations resulting from that interaction. This can result in uncertainly and decrease performance as well as overall satisfaction with the interface. We introduce a method and device that resolves these issues in stylus-based interfaces for both single and multi-user environments by providing individualized haptic and acoustic feedback. This is achieved by adding a mechanical actuator and acoustic generator to each stylus. These are controlled to respond appropriately to virtual objects and are capable of simulating a variety of physical sensations. Because the feedback is generated by the stylus rather than the screen or touch surface, the current invention can operate at the individual level even in the presence of multiple simultaneous users.

    摘要翻译： 触摸屏界面在用户尝试与虚拟对象进行交互但不会遇到由该交互产生的物理感觉时遭受视觉 - 电机冲突。 这可能导致不确定性和降低性能以及对界面的整体满意度。 我们介绍一种方法和设备，通过提供个性化的触觉和声学反馈来解决单用户和多用户环境的基于触控笔的界面中的这些问题。 这通过在每个触笔上添加机械致动器和声学发生器来实现。 这些被控制以适当地对虚拟物体进行响应并且能够模拟各种物理感觉。 由于反馈是由触笔而不是屏幕或触摸表面产生的，所以即使在多个同时使用的用户的存在下，本发明也可以在单个级别上操作。
