Signal decoding methods and apparatus
InactiveUS20050135498A1Implementation is particularly straightforwardRobust methodSpatial transmit diversityMultiplex communicationTheoretical computer scienceData structure
This invention is generally concerned with methods, apparatus and processor control code for decoding signals, in particular by means of sphere decoding. A sphere decoder configured to search for one or more strings of symbols less than a search bound from an input signal by establishing a value for each symbol in turn of a candidate said string by postulating values for each said symbol in turn of said candidate string and determining whether a said postulated symbol value results in a distance metric dependent upon said search bound being satisfied, each said symbol of a said candidate string for which values are postulated defining a level of said search. The sphere decoder includes a data structure configured to define, for each level of said search, a set of symbol values from which said postulated values are selected, said sets of symbol values being different at different levels of said search.

Beamformer for multi-beam receive antenna
InactiveUS6784838B2Efficient replacementIncrease data rateSpatial transmit diversityRadio wave direction/deviation determination systemsMultiplexingPhase shifted
A phased array antenna system that is operative to simultaneously form multiple beams without requiring an undue amount of hardware. The system collects propagating energy with a number of antenna elements to form multiple beams, encodes the beams as the energy is collected, combines the encoded beams, and then decodes the combined signal to separate the beams. In this way, the beams can be formed with a single set of antenna hardware instead of requiring a multiplicity of antenna hardware, one for each beam. Frequency coding may be implemented by repeatedly applying a Doppler phase shift to each beam, and then using a Doppler filter to separate the beams. Alternatively, a code division multiplexing technique may be implemented by using a CDMA code generator to apply a code to each beam, and then using a CDMA filter to separate the beams.

Data processor memory circuit
ActiveUS7055007B2Reduce leakageRaise the threshold voltageMemory architecture accessing/allocationEnergy efficient ICTMemory circuitsComputer science
A memory circuit for use in a data processing circuit is described, in which memory cells have at least two states, each state being determined by both a first voltage level corresponding to a first supply line and a second voltage level corresponding to a second supply line. The memory circuit comprises a readable state in which information stored in a memory cell is readable and an unreadable state in which information stored in said memory cell is reliably retained but unreadable. Changing the first voltage level but keeping the second voltage level substantially constant effects a transition between the readable state and the unreadable state. In use, the static power consumption of the memory cell in the unreadable state is less than static power consumption of the memory cell in the readable state.

The invention provides an automated hand hygiene / infection control monitoring sensor-based system suitable for improving hand hygiene and multiple infection control measures and ensuring compliance by health care workers as well as visitors to hospitals and clinics. The use of biometric identification devices such as cameras for face recognition and profiling, microphones for voice recognition, etc. permit highly accurate identification without the use of removable identification devices such as identification badges which may include bar codes, magnetic strips or wireless devices such as RFIDS. Identification badges are removable and hence susceptible to being lost, misplaced, etc. Visitors are typically not assigned identification badges and hence enforcement of hand hygiene policies is minimal. Additional applications include reducing food contamination in food industry, the spread of diseases in schools, in businesses, in corporations and governmental facilities and public access facilities such as public restrooms, dining areas and transportation.

Clustering appearances of objects under varying illumination conditions
ActiveUS7103225B2Efficiently determinedImplementation is particularly straightforwardCharacter and pattern recognitionImaging conditionHigh dimensional
Taking a set of unlabeled images of a collection of objects acquired under different imaging conditions, and decomposing the set into disjoint subsets corresponding to individual objects requires clustering. Appearance-based methods for clustering a set of images of 3-D objects acquired under varying illumination conditions can be based on the concept of illumination cones. A clustering problem is equivalent to finding convex polyhedral cones in the high-dimensional image space. To efficiently determine the conic structures hidden in the image data, the concept of conic affinity can be used which measures the likelihood of a pair of images belonging to the same underlying polyhedral cone. Other algorithms can be based on affinity measure based on image gradient comparisons operating directly on the image gradients by comparing the magnitudes and orientations of the image gradient.

Fast lapped image transforms using lifting steps
InactiveUS20080075377A1Fast and efficient and robustFast and low-cost approachCharacter and pattern recognitionDigital video signal modificationMulti bandOne pass
This invention introduces a class of multi-band linear phase lapped biorthogonal transforms with fast, VLSI-friendly implementations via lifting steps called the LiftLT. The transform is based on a lattice structure which robustly enforces both linear phase and perfect reconstruction properties. The lattice coefficients are parameterized as a series of lifting steps, providing fast, efficient in-place computation of the transform coefficients as well as the ability to map integers to integers. Our main motivation of the new transform is its application in image and video coding. Comparing to the popular 8.times.8 DCT, the 8.times.16 LiftLT only requires 1 more multiplication, 22 more additions, and 6 more shifting operations. However, image coding examples show that the LiftLT is far superior to the DCT in both objective and subjective coding performance. Thanks to properly designed overlapping basis functions, the LiftLT can completely eliminate annoying blocking artifacts. In fact, the novel LiftLT's coding performance consistently surpasses that of the much more complex 9 / 7-tap biorthogonal wavelet with floating-point coefficients. More importantly, our transform's block-based nature facilitates one-pass sequential block coding, region-of-interest coding / decoding as well as parallel processing.
