Abstract
A portable electronic device includes a housing, a drop detection part located on the housing that detects when the device is dropped into water, a light emission part located within the housing, and a light-emission control circuit located within the housing that controls emission of light from the light emission part when the drop detection part detects that the device is dropped into the water. The device is configured to have a buoyancy, and the buoyancy and a center of gravity of the device are configured to let the device float stably in a left-right lateral direction.
Claims18
A portable electronic device comprising:
- a housing;
- a drop detection part located on the housing that detects when the device is dropped into water;
- a light emission part located within the housing;
- and
- a light-emission control circuit located within the housing that controls emission of light from the light emission part when the drop detection part detects that the device is dropped into the water, wherein
- the device is configured to have a buoyancy, and
- the buoyancy and a center of gravity of the device are configured to let the device float stably in a left-right lateral direction.
A portable electronic device comprising:
- a buoyant housing;
- a drop detection part located on the housing that detects when the device is dropped into water;
- a light emission part located on the housing and in communication with the drop detection part, the light emission part being configured to emit light when the drop detection part detects that the device is dropped into the water;
- and
- a light-emission control circuit located within the housing and connected to the light emission part to control emission of light from the light emission part when the drop detection part detects that the device is dropped into the water, wherein
- the device is configured to float stably in a left-right lateral direction when the device is in the water.
