Abstract:
1. An apparatus comprising: an housing; an illumination source operative to generate an illumination light projected towards a target object; an imaging sensor in the housing for detecting light from a barcode on the target object with an array of photosensitive elements in the imaging sensor to create pixel data during an exposure time period while the barcode is illuminated by the illumination light at least during a part of the exposure time period; a controller for processing the pixel data to decode an image of the barcode; a battery in the housing for powering at least one of the illumination source, the imaging sensor, and the controller; a first light indicator operative to emit light in a first color for a duration of a first time period after a predetermined triggering event; a second light indicator operative to emit light in a second color for a duration of a second time period after the predetermined triggering event; and wherein the percentage of the first time period relative to the sum of the first time period and the second time period is configured to be a monotonic function of the percentage of energy remaining in the battery relative to the total energy in the battery that is fully charged.
