摘要:
An electrically operated device (10) for treatment of hardness of water in a pipe or other waterflow guidance or containment, and which includes an aerial (11) capable of being wrapped externally around a pipe (12); a mains-powered generator (13) for forming a waveform of a predetermined pattern and at a radio frequency; an output connection (15) on the generator to which the aerial can be connected to receive the waveform; and means for varying the frequency of the waveform to suit the diameter of pipe with which the device is to be used.
摘要:
Circuitry for selectively reducing noise which results from film granularity, circuitry imperfections and other sources of random signal degradation by averaging, non-recursively, between 2 and 9 frames of digitized video information. By such averaging, since the noise is random, it is filtered out leaving only the desired picture. The averaging is performed only on areas of the picture which are close in both amplitude and color in adjacent frames. In this connection, in cases where there is no motion or scene change between adjacent frames, the entire picture corresponding to such frames can be processed according to the present invention.

A policy proxy intercepts a data stream between a data server and a user or other device, identifies the user device, and identifies a policy in an integrated policy server applicable to the user device based on the identity of the user device. The policy proxy may identify one or more of the policy elements based on the user device, and translate the policy elements into actions involving the data stream between the data server and the user device so as to implement at least one aspect of the identified policy. The actions can comprise permitting normal exchange of data between the data server and the user device, preventing communication between the data server and the user device, or modifying the data stream between the data server and the user device.

The invention relates to providing policy from an integrated policy server to a mobile device, comprising identifying a policy in an integrated policy server applicable to the mobile device and supplying policy elements to policy transports for transmission to the mobile device. The invention also relates to providing policy from an integrated policy server to a mobile device, including identifying a policy in the integrated policy server applicable to the mobile device, determining whether the mobile device is in compliance with the policy, and supplying policy elements to policy transports for transmission to the mobile device when the mobile device is not in compliance with the policy. The invention further relates to controlling access to a data server by a mobile device, including identifying a policy in an integrated policy server applicable to the mobile device, and determining whether the mobile device is in compliance with the policy.
