Abstract: A system and method for designing a seismic survey including selecting a seismic survey grid as a basis for a seismic survey design and looping through the steps of generating off-the-grid locations by imposing spatial or temporal constraints on on-the-grid locations, mapping the off-the-grid locations from a physical domain to a pre-selected domain by applying a multidimensional transform to the off-the-grid locations, mapping the pre-selected domain to a rank-revealing domain using a pre-selected operator, applying a pre-selected process to minimize a rank of the off-the-grid locations in the pre-selected domain, and updating the seismic survey design based on which of the off-the-grid locations has the minimum rank until a pre-selected threshold is met indicating an optimal seismic survey design. The system and method include acquiring seismic data using the optimal seismic survey design, and enabling performing a wellsite action based at least on the seismic data.

Abstract: System and method for designing dithers having a pre-determined distribution within a dithers range, wherein the dithers range is chosen for the seismic survey, wherein a lower boundary of the dithers range is 4 seconds or +2 seconds dithers distribution relative to nominal shotting times of sources of seismic waves in the seismic survey, and wherein an upper boundary of the dithers range is a largest value compatible with constraints of the seismic survey.

Abstract: The invention relates to a control apparatus for a refrigerator compressor having at least one two-phase AC asynchronous motor (K1, K2), having mains connection means (10) for connection to a preferably public voltage supply network which nominally provides a mains AC voltage of between 85 V and 264 V, in particular between 100 V and 230 V, first voltage converter means (14) which are connected downstream of the mains connection means and are intended to generate an intermediate voltage, in particular an intermediate DC voltage, from the mains AC voltage, second voltage converter means (16-1, 16-2) which are connected downstream of the first voltage converter means and are intended to generate an output signal which is independent of a level and a mains frequency of the mains AC voltage, in particular has a constant voltage and/or frequency in periods, and is intended to control the refrigerator compressor with an AC voltage of a plurality of differently predefinable voltage levels, wherein the mains connecti

Abstract: The invention relates to a grid voltage-operated refrigerating device, in particular an ultra-low-temperature refrigerating device, comprising a refrigerator door (2) which has a closure lever (22) that is pivotally hinged between an open position and a locked position and comprising locking means (24) which are paired with the closure lever, have an electric motor-actuated and/or electromagnetically actuated locking element (26) and lock or release the pivoting of the closure lever depending on a code actuation that can be entered by an operator using a code input unit (20). The locking means and the code input unit are paired with an electronic control unit (14) and grid voltage-independent battery buffering means (13) such that in response to a grid voltage outage, the code actuation and a release for a specified minimum period of time are made possible without a grid voltage supply.

Abstract: A health potential study and summary makes use of a multiple-page, relatively comprehensive, questionnaire for the individual, an analysis of answers to the questionnaire in readable summary form and an abbreviated life-style resume of the analysis coupled with a visually graphic portrayal of health potential on a graduated scale. The questionnaire is divided into different categories of health affecting subjects arranged so that answers in the form of yes, no, unanswered, or degree rated against a specified rate scale, are placed in a score box adjacent the question. The questionnaire includes an actual food intake diary for a specified period of days and an exercise report. The analysis and appropriate comments are presented in printed form for the respective categories in a manner comparing ideal conditions against actual conditions of the individual where prevailing conditions are picked from the score boxes and commentary and recommendations selected from a data bank according to score.
