International Classification:

US Classification:

342175

Abstract:

The objective of this patent is to develop new signal processing algorithms for a wide-band circular electronically scanned array (CESA) or a wideband linear electronically scanned array (LESA) for use in surveillance and communications applications, where a sequence of pulses are transmitted and their returns are collected by the array for further processing. Instead of partitioning the entire wideband frequency into various subbands and then processing them separately using narrowband schemes, a frequency focusing method is proposed here to compensate and focus the wideband spatio-temporal data into a single narrow frequency band. This is made possible by operating with a pre-computed frequency focusing matrix that transforms the data from various frequency slots that are spread across the entire wideband region into a common narrowband frequency for the array outputs. Finally the focused narrowband data can be processed using conventional space-time adaptive processing methods to suppress the clutter/noise returns and detect any targets present.

US Classification:

Abstract:

A new method for transmitter-receiver design that enhances the desired signal output from the receiver by whitening the total interference and noise input to the receiver and maximizing the output Signal to Interference plus Noise power Ratio (SINR) is presented. As a result of the whitening process, the receiver “sees” a desired signal in white noise, and the receiver structure is then optimized to maximize the receiver output at the desired decision making instant. Furthermore the new design scheme proposed here can be used for transmit signal energy and bandwidth tradeoff. As a result, transmit signal energy can be used to tradeoff for “premium” signal bandwidth without sacrificing the system performance level in terms of the output Signal to Interference plus Noise power Ratio (SINR).

US Classification:

702 77, 702 66, 702 70, 702 71

Abstract:

One or more embodiments of the present invention relates to an iterative method for generating an almost-constant, nearly constant, or substantially-constant envelope time signal with prescribed Fourier transform magnitude in the frequency domain, and a constant envelope time signal whose Fourier transform magnitude closely matches the prescribed Fourier transform magnitude in the frequency domain. Different starting points for the iterative algorithm give rise to different solutions and their accuracy can be adjusted using a monotonic error criterion presented here.

Abstract:

A camera includes a first microphone, a second microphone, one or more drains, and a processor. The processor determines a correlation metric between portions of audio signals obtained from the first and second microphones. The one or more drains drain water away from the first microphone, the second microphone, or both. The camera includes a memory to store the portions of the audio signals as portions of an output audio signal.

International Classification:

G06F 8/38

H04L 67/04

Abstract:

Techniques are described for determining a duration for a transition and alteration of the appearance of a user interface (UI) from a first UI state to a second UI state over the transition duration according to a timing function that specifies different rates of change in appearance over the course of the transition and is derived by adjusting a master timing function that is used to control a plurality of transitions in the UI to span the transition duration for the transition. A time value of an inflection point within the timing function is determined and the transition duration is divided into a first portion and a second portion so that the first portion extends from the beginning of the transition duration to the time value of the inflection point, and the second portion extends from the time value of the inflection point to the end of the transition duration.

Abstract:

A method of cuff storage case for an electronic blood pressure monitor includes an electronic blood pressure monitor main part, cuff, and a cuff storage case. one end of the air tube connects to a side of the electronic blood pressure monitor main part, and the other end of the air tube connects to a cuff. When the electronic blood pressure monitor main part is not in use, the cuff can place inside the cuff storage case. The Cuff storage case connects to the electronic blood pressure monitor main part through the connecting element. The structure of this invention is reasonable. The cuff storage case fixes on the electronic blood pressure monitor main part through the connecting element and will not restrict the models and shapes of the electronic blood pressure monitor. It can apply to most kinds of electronic blood pressure monitors.
