Patent number: 9119587
Abstract: A method and apparatus for the improved display of digital mammographic images, which were measured in the context of a mammographic imaging system and displayed on a workstation monitor. The mammogram consists of a plurality of pixels with each pixel having a pixel value assigned thereto. The pixel values of all pixels of the mammogram lie within a pre-determined first range of values and the pixel values of pixels of a subsection of the mammogram lie within a second range of values, which represents a subset of the first range of values. A mammogram having a subsection with increased contrast, such that the second range of pixel values of the pixels in the subsection are spread by a spreading function, whereby the amount of the spreading function changes over the subsection. In this way, an improved display is created, by means of those representations of the mammogram regarding their contrast in subsections being optimized, at the same time the representation for a user is improved without artifacts.

The first converter generates a first output current. A second output current is generated by a second converter and is added to the first output current. The second output current is generated such that an actual current over the load follows a desired current.

Abstract: Methods and apparatuses may be provided for utility meters or other devices with communications prioritization. The methods and apparatuses may include receiving first information addressed to or from a first network device of the one or more network devices; determining that the first network device is either (i) battery-powered or associated with a limited power source, or (ii) associated with wireless communications; and based upon the determination that the first home device is either (i) battery-powered or associated with a limited power source, or (ii) associated with wireless communications, identifying the first information as higher priority. The identification of the first information as higher priority may result in the utility meter or other device processing of the first information ahead of one or more second information designated as lower priority.
