  • Publication number: 20060234749
    Abstract: It is possible to operate a wireless system, such as a CDMA system, in a more efficient manner by employing a statistical approach for setting power targets for reverse loop transmission. Unlike present methods for setting such targets a figure-of-merit quantity such as the frame error rate need not be measured to set the reverse loop transmission power for a wireless unit. Instead the target is set on a statistical basis established by sampling. Real time measurement of a quantity-of-merit is not required. A statistical approach produces among other things a decreased sensitivity to rapid changes in transmission conditions.

  • Publication number: 20050227697
    Abstract: Techniques and systems for channel prediction in wireless networks. A base station receives a succession of channel indicators from each of a plurality of mobile units, each channel indicator being received from each mobile unit once per timeslot. A channel predictor uses the channel indicators to generate a channel condition prediction for each mobile unit, the channel condition prediction being based on a balanced estimate using the most recent channel condition indicator and the mean of the succession of channel indicators. A weight is computed based on a gradient of the succession channel indicator values and used to assign relative emphasis to the most recent channel condition indicator and the mean channel condition indicator in order to give greater emphasis to the most recent indicator during slowly changing conditions and greater emphasis to the mean indicator during rapidly changing conditions.

  • Publication number: 20040214577
    Abstract: Techniques and systems for planning of wireless networks are described. A system according to an aspect of the present invention receives inputs describing traffic statistics for a wireless network and computes network specifications. The system uses the traffic statistics and network specifications as inputs to a computationally tractable model used to compute parameters for the user level performance of the wireless network. The model may suitably be a processor sharing queuing model. The model employed by the planning system allows analytical solution for the desired user level parameters, given the characteristics and conditions entered as inputs and the intended network layout characteristics. Once a set of user level performance parameters has been computed, the values of the parameters are examined to determine if they meet predetermined requirements, in an iterative process continuing until a set of specifications has been developed that produces parameters meeting the requirements.

  • Patent number: 6763009
    Abstract: A base station of a code division, multiple access (CDMA) telecommunications system employs scheduling of data transmission signals to corresponding user transceivers in down-link channels of a data network. One or more user transceivers may be in communication with a base station within a cell, and each user may have a minimum data rate requirement. In accordance with the present invention, the scheduling of user data transmission follows the constraints that 1) each base station transmits to user transceivers one at a time, and 2) the base station uses full available power for the down-link channel when transmitting (for data networks only). Given a data network of users, the method of scheduling and data rates may be modeled in accordance with a linear programming problem optimized according to a predefined criterion. In addition, the present method may be employed in a hybrid CDMA/time-share system to reduce power of data channels in communication with user transceivers near the base station.

  • Publication number: 20030205509
    Abstract: A system for monitoring fluid treatment and fluid quality comprising a fluid treatment apparatus, at least one treatment-effectiveness sensor adapted, and positioned relative to said treatment apparatus, so as to sense the effectiveness of treatment performed by the treatment apparatus, and so as to emit an alarm signal when the effectiveness of treatment falls outside a predetermined range, and a monitoring system positioned remotely from the treatment apparatus and the treatment effectiveness sensor, the monitoring system being operatively connected to the treatment-effectiveness sensor, the monitoring system being adapted to receive said alarm signal and to indicate an alarm condition in response to said alarm signal.

  • Patent number: 6103129
    Abstract: A method for oxidizing organic material in an aqueous stream containing one or more inorganic salts, inorganic salt precursors or mixtures thereof comprises oxidizing the organic material in a reactor at a temperature at least equal to the critical temperature of the aqueous stream so as to form a single homogeneous fluid phase and at a pressure sufficiently high to solubilize the inorganic salts in the single homogeneous phase.

  • Patent number: 6056883
    Abstract: A supercritical water oxidation reactor is alternately supplied with a feed stream and a flushing stream. The feed stream contains organic and inorganic materials. The organic materials are oxidized under supercritical conditions in the reactor and the inorganic materials precipitate out of solution under the same conditions. The flushing stream is a solution in which the inorganic material is soluble. More than one supercritical water oxidation reactor may be connected so that the feed stream is alternately supplied to each reactor. During the period when the feed stream is being supplied to a reactor the effluent from the reactor is cooled to a temperature at which inorganic precipitates are soluble and is then supplied as a flushing stream to one or more of the remaining connected supercritical water oxidation reactors.

  • Patent number: 5667698
    Abstract: A supercritical water oxidation reactor is described having first and second reaction zones connected in series and through which an aqueous feed stream to be oxidized can be passed in either direction. A self-contained heat exchange fluid system allows supercritical and subcritical temperatures to be maintained in either reaction zone. When supercritical water oxidation is occuring in one reaction zone the effluent is being cooled to a subcritical temperature and used to flush the second reaction zone to remove inorganic scale.
