A power and control architecture employing circuitry that sequentially regulate power flows from independent solar-array sources or a mixture of power sources providing power to a common load. The device may be used on a satellite with solar-array sources; however it may also be used on ground based systems. Stiff bus voltage regulation is obtained by tightly controlling the most recently activated power-processing channel while keeping the previously activated power-processing channels in the Maximum Power Tracking mode to supply maximum power to a common load. The remaining power-processing channels are turned off or operated in stand-by mode. In an alternative system, with primary design goal of uniform power sharing among solar-array sources, all solar array sources are activated with uniform power sharing at light load and, as load demand increases, sequentially controlled to operate in the Maximum Power Tracking mode one solar array source at a time as necessary.

An electronic instrument display is configured to present parameter images, at least one of which includes a first indicator configured to indicate a specific value (e.g., a target value) for a flight parameter and a second indicator configured to indicate an actual flight parameter value that changes according to variations in the flight parameter. A graphics rendering controller is configured to generate the parameter images and to enlarge a portion of the parameter image when the actual flight parameter value is within a predetermined range from the target value.

A CVD-coated cutting tool insert with a TiC_xN_y-layer with a low tensile stress level of 10-300 MPa and an α-Al₂O₃-layer with a high surface smoothness of <0.1 μm as measured by AFM-technique is disclosed. This is obtained by subjecting the coating to a first intensive wet blasting operation with a slurry of F80 grits of Al₂O₃ followed by a second wet blasting treatment with a slurry of F320 grits of Al₂O₃.

This invention relates to a system and a kit for stress and relaxation management. A cardiac activity sensor (101) is used for measuring the heart rate variability (HRV) signal of the user and a respiration sensor (102) for measuring the respiratory signal of the user. The system contains a user interaction device (103) having an input unit (104) for receiving user specific data and an output unit for providing information output to the user. A processor (106) is used to assess the stress level of the user by determining a user related stress index. The processor is also used to monitor the user during a relaxation exercise by means of determining a relaxation index based on the measured HRV and respiratory signals, the relaxation index being continuously adapted to the incoming measured signals and based thereon the processor instructs the output unit to provide the user with biofeedback and support messages. Finally, the processor uses the user specific data as an input in generating a first set of rules defining an improvement plan for self-management of stress and relaxation. The first set of rules is adapted to trigger commands instructing the output unit to provide the user with motivation related messages. Also, at least a portion of said user specific data is further used to define a second set of rules indicating the user's personal goals.

A method of processing images of at least one living being, includes obtaining a sequence (19) of digital images taken at consecutive points in time.
