Abstract
A memory card with an indicator light has a casing, a processor, an input/output (I/O) interface, memory and an indicator light module. The indicator light module is mounted in the casing and connected to the I/O interface and has an inductor, an LED and a resistor. The inductor is connected to the I/O interface and has an input end and an output end. The LED is mounted on the casing and connected to the output end of the inductor. The resistor is connected in series with the LED. When the LED is not on, electrical power is not being provided to the proper pin on the I/O interface from the digital device. Consequently, any fault observed when the LED is not on can be attributed to a fault in the digital device.
Claims10
A memory card with an indicator light comprising:
- a casing;
- a processor mounted in the casing and controlling operation of the memory card;
- an input/output (I/O) interface mounted in and exposed through the casing, connected to the processor and having specific pins to transfer data and obtain electrical power from a digital device;
- memory mounted in the casing and connected to the I/O interface and the processor;
- and
- an indicator light module mounted in the casing to monitor an external power source in a digital device through the I/O interface and comprising
- an inductor connected to the I/O interface and having
- an input end connected to the pin on the I/O interface,
- which connects to a power source in a digital device;
- and
- an output end;
- an LED mounted on the casing, being visible when the memory card is adapted to be plugged into a digital device, connected to the output end of the inductor and emitting light when the correct pin on the I/O interface is adapted to obtain electrical power from the digital device;
- and
- a resistor connected in series with the LED.
