    • An incoming RF signal can be amplified in a RF front end of a RF receiver by conveying the signal through one of a multiple amplification paths. On each path, the gain can be controlled by RF automatic gain control (AGC) circuits. Each amplification path can be designed to handle incoming signals in a designated power range and to optimize receiver performance characteristics such as the noise figure (NF) and odd harmonic linearity in that power range. Signal power can be measured at different locations of the receiver and bypass switches can be used to convey the RF signals down one of the multiple paths based on the power measurements, according to executable logical code. An incoming signal power hysteresis can be applied to stabilize the system. Further, signal power averaging and switch delaying mechanisms can be employed to stabilize the system for rapidly fluctuating signals.
    • 通过将信号传送通过多个放大路径中的一个,RF射频信号可以在RF接收器的RF前端中放大。 在每个路径上,增益可由RF自动增益控制(AGC)电路控制。 每个放大路径可被设计为处理指定功率范围内的输入信号,并优化接收机性能特征,例如该功率范围内的噪声系数(NF)和奇次谐波线性度。 可以在接收机的不同位置测量信号功率,根据可执行逻辑代码,旁路开关可用于基于功率测量将射频信号传送到多个路径之一。 可以应用输入信号功率滞后来稳定系统。 此外,可以采用信号功率平均和开关延迟机制来稳定系统以实现快速波动的信号。

    • Methods and devices for implementing a camera restriction on a wireless handheld communication device. As more handheld devices incorporate camera functionalities, organizations and individuals with privacy concerns are more vulnerable to unauthorized disclosure. The camera restriction prevents a user from taking a picture of a subject if the device has not been steadily focused on the subject in question for a predetermined period of time. In short, this process extends the normal camera-taking procedure and thus requires the camera user to take pictures in a conspicuous manner—the rationale being that a camera user would be less likely to take unauthorized pictures if such actions could be easily recognized. The camera restriction can be communicated to the device via a wireless communication network. Additionally, the restrictions and boundaries can be communicated to the device as part of an IT security policy.
    • 用于在无线手持通信设备上实现相机限制的方法和设备。 随着越来越多的手持设备采用相机功能,具有隐私问题的组织和个人更容易受到未经授权的披露。 如果设备在预定的时间段内没有稳定地关注所讨论的被摄体,则相机限制防止用户拍摄被摄体的照片。 简而言之,这个过程扩展了正常的相机拍摄过程,因此需要相机用户以显着的方式拍摄照片 - 这样的理由是,如果可以容易地识别出这样的动作,照相机用户将不太可能拍摄未经授权的照片。 相机限制可以经由无线通信网络传送到设备。 此外,作为IT安全策略的一部分,限制和边界可以传达给设备。

    • A monitoring device makes decision on whether a service requested by a consumer is a sponsored service to the specific consumer or not based on sponsoring rules, i.e. the delivery of the requested service to the consumer can be sponsored if a sponsoring value of the consumer is sufficient in relation to a charge of delivery of the requested service. The sponsoring rules contain various pieces of information for recognizing a sponsored service and for determining the sponsoring value and the cost of the delivery. The sponsoring of different services to different consumers can be controlled, created, deleted, maintained or modified by means of the sponsoring rules. The sponsor, such an advertiser is able to control the cost of sponsoring by affecting the sponsoring value.
    • 监控设备根据赞助规则来确定消费者所要求的服务是否是对特定消费者的赞助服务,即,如果消费者的赞助价值足够,则可以赞助向消费者传送所请求的服务 关于要求服务的交付费用。 赞助规则包含用于识别赞助服务和确定投放价值和交付成本的各种信息。 可以通过赞助规则来控制,创建,删除,维护或修改不同服务对不同消费者的赞助。 赞助商,这样的广告商能够通过影响赞助价值来控制赞助成本。
