Claims16
An information display device adaptable in a ward to display patient information, comprising:
- a control circuit;
- an electronic paper (epaper) module configured to be controlled by the control circuit for displaying patient information;
- a solar charging panel configured to output a first voltage;
- a battery configured to output a second voltage;
- a rechargeable energy storage device, and
- a voltage regulating circuit coupled to the solar charging panel, the battery, and the rechargeable energy storage device and configured to provide an operational voltage to the control circuit and the epaper module.
An information display device, comprising:
- a control circuit;
- an electronic paper (epaper) module, configured to be controlled by the control circuit for displaying patient information;
- a USB connector, wherein only a VCC pin thereof is coupled to a constant current circuit, and a GND pin thereof is coupled to ground;
- a solar charging panel;
- a battery;
- a rechargeable energy storage device;
- and
- a voltage regulating circuit coupled to the solar charging panel, the constant current circuit, the battery, and the rechargeable energy storage device, and configured to provide the control circuit and the epaper module an operational voltage,
- wherein the constant current circuit is configured to provide power to the voltage regulating circuit only when the USB connector is coupled to an external device.
An information display device adaptable in a ward to display patient information, comprising:
- a solar module;
- a battery;
- a supercapacitor module;
- a voltage regulating circuit coupled to the solar module, the batter, and the supercapacitor module;
- an electronic paper (epaper) module;
- and
- a controller, configured to control the epaper module for displaying patient information, wherein the voltage regulating circuit selectively charges the supercapacitor module using the solar module and the battery, wherein the epaper module and the controller are primarily powered by the supercapacitor module.
