Abstract:
1. A system for transmitting a signal, the system comprising: a battery having a voltage supply level; a transmitter electrically coupled with the battery, the transmitter having a button, the transmitter transmitting data via a signal when a user presses the button; a controller circuit, the controller circuit electrically coupled with the transmitter, the controller circuit having data transmittable by the transmitter, the data coded to actuate a garage door opener; and a battery status circuit, the battery status circuit comprising a voltage reference circuit and a comparator circuit, the battery status circuit electrically coupled with the battery to determine the voltage supply level of the battery each time the transmitter transmits data by measuring a reduction in a voltage level across at least one circuitry element electrically coupled to the battery status circuit, the voltage level indicating a present strength of the signal of the transmitter, a first, a second, and a third voltage status light emitting diode (LED), each of the voltage status LEDs electrically coupled with the battery status circuit, the first voltage status LED emitting a first color of light, the second voltage status LED emitting a second color of light, and the third voltage status LED emitting a third color of light, the colors of light each being different and each representing a particular different output voltage, the battery, the transmitter, the controller circuit, and the battery status circuit are enclosed in a housing.
