A method, apparatus for executing the method, and computer program products for use in such an apparatus. The method includes scanning an interrogating light across multiple sites on an array package including an addressable array of multiple features of different moieties, which scanned sites include multiple array features. Signals from respective scanned sites emitted in response to the interrogating light are detected. The interrogating light power is altered for a first site on the array package during the array scan, based on location of the first site or on a determination that the emitted signal from the first site will be outside a predetermined value absent the altering (which allows for protecting a detector against expected overly bright sites), or is altered during the array scan based on the detected interrogating light power (which allows for compensating for light source drift during an array scan).

The present lighter includes two basic components, a housing and a fuel cartridge. The housing may comprise multiple pieces. The fuel cartridge is easy to remove from the housing without the use of any tools. Thus, an empty fuel cartridge can quickly be replaced with a full one by the user. Replacing the fuel cartridge, rather than refilling it, prevents the user from coming into contact with lighter fuel. The housing and the fuel cartridge are each relatively inexpensive to mass produce. Thus, a worn or damaged housing may be removed from the lighter by the user and replaced with a new housing. The disposability and replaceability of the lighter components makes repairs to the lighter quick and inexpensive. All or part of the housing may also be replaced with a housing having a different outward appearance. A user can thus change the appearance of his or her lighter by changing housings, rather than having to purchase multiple lighters. The housing may include surface features, such as bosses, ribs and / or tensioning springs, to tighten a fit of the housing and prevent spontaneous separation. The surface features may also protect the appearance of the housing.
