Abstract
Disclosed is an automatically-activated body-wearable code symbol reading system comprising a bar code symbol reading mechanism contained within a body-wearable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner. Each time the scanned bar code symbol is successfully read during a bar code symbol reading cycle, a new bar code symbol character string is produced, while an indicator light on the housing is actively driven. During the bar code symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a curre…
