Abstract: The invention is related to an image selection method comprising the following steps: a) automatically and randomly selecting (100) at least one, so-called, reminder digital image (108), amongst a collection (102) of digital images, b) automatically selecting at least one subset (130, 130a) of, so-called, linked digital images amongst the collection of images, the linked images being selected based on a similarity computation with the randomly selected reminder image, c) temporarily displaying (104) the reminder image on a display screen and stetting (106) a first user interface in an interaction detection mode whilst the reminder image is displayed, d) in response to a user interaction with the first interface whilst the reminder image is displayed, displaying simultaneously at least part of the subset of linked images determined in step b) and setting a second user interface in a selection mode in which a user can select at least one image amongst the displayed subset of linked images, e) in response to the

Abstract: A fast thermal cycler has a temperature chamber divided into a top, hot compartment heated by heating lamps and a bottom cold compartment cooled by liquid nitrogen, for optimizing thermal cycling rates for devices under test, such as solar cells, for rapid thermal life testing where both compartments use pressurized gaseous nitrogen for thermal conduction and regulation and a motor drive repetitively transports a test device mounted on a panel transiting between the two compartments. The thermal cycler is enhanced by computer control, enabling in-situ electrical testing, fail-safe heating, precision temperature heating and cooling phases, operator alerting and thermal gradient control during the temperature cycling.
