    • A method and system improves signal acquisition in a Global Positioning System (GPS) receiver by providing information to focus the acquisition search in the receiver. In particular, the invention relates to the case where a GPS receiver is integrated with a transceiver that is capable of communicating with a cellular or PCS network via the air-interface particular to that network. Standard information provided by the network is used to assist the integrated GPS receiver and improve its sensitivity and latency. The result of this improvement is that the receiver can rapidly acquire satellites and compute its position in environments where conventional, stand-alone GPS receivers cannot. This added performance is very important for the emergency location application, since the user may have high expectations for personal safety in a variety of situations. Furthermore, the rapid acquisition reduces power consumption, which is very important for battery-powered devices utilizing such combined GPS and cellular technologies.
    • 一种方法和系统通过提供信息来改善在全球定位系统(GPS)接收机中的信号采集,以将采集搜索集中在接收机中。 特别地,本发明涉及GPS接收机与能够通过该网络特定的空中接口与蜂窝或PCS网络进行通信的收发机集成的情况。 由网络提供的标准信息用于协助集成GPS接收机,提高其灵敏度和延迟。 这种改进的结果是,接收机可以在传统的独立GPS接收机不能的环境中快速获取卫星并计算其位置。 这种增加的性能对于紧急位置应用非常重要,因为用户可能对各种情况下的人身安全有很高的期望。 此外,快速采集降低了功耗,这对于使用这种组合的GPS和蜂窝技术的电池供电的设备来说是非常重要的。

    • A method for scheduling another time for a communication session when a called party is presently unable or unwilling to accept an incoming call. A first user's communications device receives a request for a communication session from a second user's communications device. Upon failure to accept the request, a server automatically forms a calendar data object, such as in response to receipt of a scheduling trigger message from the first communications device that includes an indication of the failure to accept and an identifier of the second user. The calendar data object includes scheduling information indicating, explicitly and/or implicitly, future time(s) when the first user is available. The calendar data object is sent to either one of the devices, and a time is selected. The server then notifies the other device of the selected time. Corresponding devices are also described.

    • The method and apparatus enables a user to “feel” remote objects depicted in a visual scene. Exemplary embodiments of the invention detect image texture in a digital scene and generate tactile feedback control signals as a function of the detected image texture. In one exemplary embodiment, edge detection techniques are used to detect discontinuities in the digital scene, such as sharp changes in image luminous intensity. Tactile feedback is produced responsive to the tactile feedback control signals by a tactile feedback device. The tactile feedback may be in the form of a vibration and the tactile feedback device may be a vibrator. The strength of intensity of the vibration may be varied depending on the discontinuities in the digital scene.
    • 该方法和装置使得用户能够“感觉”在视觉场景中描绘的远程对象。 本发明的示例性实施例检测数字场景中的图像纹理,并产生作为检测到的图像纹理的函数的触觉反馈控制信号。 在一个示例性实施例中,使用边缘检测技术来检测数字场景中的不连续性,例如图像发光强度的急剧变化。 通过触觉反馈装置响应于触觉反馈控制信号产生触觉反馈。 触觉反馈可以是振动的形式,并且触觉反馈装置可以是振动器。 振动强度的强度可以根据数字场景中的不连续性而变化。
