Title: Low-power direct digital synthesizer with analog interpolation
Inventor: FAHIM AMR M
IPC: H03K5/135
Filed: 2004-10-14
Abstract: An MN counter with analog interpolation (an "MNA counter") includes an MN counter, a multiplier, a delay generator, and a current generator. The MN counter receives an input clock signal and M and N values, accumulates M for each input clock cycle using a modulo-N accumulator, and provides an accumulator value and a counter signal with the desired frequency. The multiplier multiplies the accumulator value with an inverse of M and provides an L-bit control signal. The current generator implements a current locked loop that provides a reference current for the delay generator. The delay generator is implemented with a differential design, receives the counter signal and the L-bit control signal, compares a differential signal generated based on the counter and control signals, and provides the output clock signal. The leading edges of the output clock signal have variable delay determined by the L-bit control signal and the reference current.

Title: Rate selection for a multi-carrier mimo system
Inventor: KADOUS TAMER
IPC: H04L1/16
Filed: 2004-10-13
Abstract: To select a rate for data transmission in a multi-carrier MIMO system with a multipath MIMO channel, a post- detection SNR for each subband k of each spatial channel is initially determined and used to derive a constrained spectral efficiency based on a constrained spectral efficiency function of SNR and modulation scheme M. An average constrained spectral efficiency for all subbands of all spatial channels used for data transmission is next determined based on the constrained spectral efficiencies for the individual subbands/spatial channels. An equivalent SNR needed by an equivalent system with an AWGN channel to support a data rate of is determined based on an inverse constrained spectral efficiency function. A rate is selected for the multi-carrier MIMO system based on the equivalent SNR. The selected rate is the highest rate among all supported rates with a required SNR less than or equal to the equivalent SNR.

Filed: 2003-11-28
Abstract: A method of forming glass with substantially reduced inclusions and cord includes reducing a shear force while maintaining a predetermined stirring efficiency in a stirring operation by properly selecting a stirrer diameter, a stirrer speed and a coupling distance. A stirring apparatus (100) includes a stirring vessel (101), which receives the fluid glass (105) at an input (107). This glass is then stirred by rotation of a shaft (104) having a stirrer (103) to improve the homogeneity of the glass material (106) that is delivered at the output (108). The coupling distance is the distance between the edges of the stirrer blades and the interior walls (102) of the stirring vessel. The glass may be used to form glass sheets for use in flat panel displays such as liquid crystal displays for use in computer monitors, personal digital assistants, and cellular telephones. The glass sheets may have thin film transistor elements formed thereon for use in forming pixels on the display.

Title: System for controlling the level of potential pollutants in a waste treatment plant
Inventor: GNEDENKO VALERI G
IPC: B03B9/06
Filed: 2005-03-17
Abstract: The invention is an apparatus and method for on-line sorting of waste matter, at the entrance to a waste processing plant, according to the level of specific chemicals, typically chlorine detected therein. The apparatus comprises a waste matter inlet that provides waste matter to a weighing module, preferably until a preset limit is reached. Then, this control volume of waste is introduced into a pulsed neutron material analyzer that is optimized for the determination of the content of the specific chemical in the control volume. A control means such as a computer then decides whether the level of the chemical in the waste control volume is above or below a preset threshold, and accordingly channels the waste into one or another of two channels. One of these channels accepts waste with low content of the given chemical, for introduction into the waste processing chamber. The other channel stores the waste until, for example, it may be mixed with other waste having a sufficient low content such that the overall amount of the chemical is still below the threshold value.
