摘要： Systems and methods for the multispectral imaging of skin tissue enables automatic characterization of the condition of a region of interest of the skin, based on direct digital imaging of the region of interest (Figures 1a, 2) or the digitization of color photographic slides of the region of interest, illuminated by appropriately filtered light. Preferably, a digital image at a low spectral band is automatically segmented and that segmented mask is used to segment the other images by a digital processor (Figure 3b). Parameters are estimated through wavelet maxima representation. Parameters related to the texture, asymmetry, blotchines and border irregularities are also automatically estimated (Figure 11). The region of interest is automatically characterized by the digital processor, based on those parameters. The region of interest may include a skin lesion, in which case the present invention enables the characterization of the lesion as malignant or benign (Figures 4a, 4b).

摘要： Among other things, a texture of an image is characterized by deriving entropy-based lacunarity parameters from density distributions generated from the image based on a wavelet analysis. In some examples, lacunarity descriptors are extracted from textured regions using wavelet maxima. The distributions of the local wavelet maxima density in a sliding window over the region of interest are compared using different methods in order to generate lacunarity parameters.

摘要： A novel fully integrated adjustable DC current reference is developed. The reference current is set by the ratio of a DC voltage generated using a band-gap reference and a tuned resistor based on an inductor reference. An AC signal is necessary to develop a relationship between the resistor tuned and the inductor reference. A computation unit which could be designed as an analog circuit is necessary to compute the value of the resistor in relationship to the reference inductor. Classic circuits are used to develop and analyze the relationship between the reference inductor and the tunable resistor that sets the DC current reference. Results show that the value of the inductance is insensitive to process, voltage and temperature variations. Therefore, assuming the DC bandgap reference voltage is insensitive to changes in process, voltage and temperature variations, so is the the DC current reference.

摘要： A monolithic transformer compensated circuit with enhanced quality factor without significantly increasing noise levels is presented in this disclosure. The technique uses a monolithic transformer and a current source driving current into the transformer secondary winding to achieve loss compensation in the transformer primary. An ac current which is proportional to, and in phase with the voltage applied to the primary winding can be used to achieve theoretically perfect loss compensation at a given frequency in the RF (GHz) frequency range. Examples of circuit applications that are particularly suited to the technique include Voltage Controlled Oscillators (VCO's), Low Noise Amplifiers (LNA's) and Filters. The technique has the added advantage of reducing power consumption in some applications.
