Abstract
A scale with a transiently visible display includes: an enclosure having an upper surface; a measurement device disposed in the enclosure; and a display coupled to the measurement device and attached to the enclosure beneath the upper surface, the display displaying a measurement value only when the display is an active state. Activation of the measurement device places the display in the active state whereas deactivation removes the display from the active state. The enclosure obscures the display from visibility when the display is not in the active state. Optionally, the scale may include a facade beneath the upper surface and a shutter adjacent the facade and covering the display, the shutter being coupled to the measurement device. The shutter opens to reveal the display during activation. The enclosure obscures the facade and the shutter from recognition when the measurement device is not in the active state.
