Abstract

A system is disclosed that includes memory resources and one or more processing components coupled to the one or more memory resources. At least one of the memory resources stores a basic input/output system (BIOS). The one or more processing components are coupled to the memory resources to run a program for operating a point-of-sale (POS) terminal. The program enables a user to provide an input to open a cash drawer. A controller circuit receives a signal from the BIOS when the user provides the input and generates a pulse signal having a predetermined duration to cause a voltage signal to be transmitted to a solenoid of the cash drawer. The voltage signal causes the solenoid to change states in order to open the cash drawer.

First claim

What is claimed is:

1. A system comprising:
a super I/O controller circuit;
a voltage regulator;
a switch to receive input from the super I/O controller circuit and the voltage regulator;
one or more processors; and
one or more memory resources storing a basic input/output system (BIOS), the one or more memory resources further storing instructions that, when executed by the one or more processors, cause the system to:
detect a user input to unlock a cash drawer operable by a solenoid of a point of sale (POS) terminal; and
in response to the user input, (i) cause the voltage regulator to generate and transmit a voltage signal, having a predetermined voltage, to the switch, and (ii) run the BIOS to assert the super I/O controller circuit to generate and transmit a pulse signal, having a configurable duration, to the switch, causing the switch to transmit the voltage signal to the solenoid for the configurable duration;
wherein the transmitted voltage signal causes the solenoid to change states and unlock the cash drawer.

2. The system of claim 1 , wherein the super I/O controller circuit comprises an internal timer, and wherein the configurable duration of the pulse signal is based, at least in part, on the internal timer.

3. The system of claim 2 , wherein the configurable duration of the pulse signal is configurable via a user interface of the BIOS, the user interface providing access to BIOS settings enabling a user to configure or adjust the internal timer to set the configurable duration of the pulse signal.

4. The system of claim 3 , wherein the user interface further enables the user to configure or adjust the predetermined voltage of the voltage signal.

5. The system of claim 1 , wherein the pulse signal causes the voltage signal to be transmitted to the solenoid by changing states of the switch coupled to the super I/O controller circuit.

6. The system of claim 1 , further comprising a physical interface coupled to the switch, wherein the cash drawer is coupled to the physical interface.

7. The system of claim 1 , wherein the switch is a transistor.

8. The system of claim 1 , further comprising a display screen, and one or more input mechanisms.

9. A point-of-sale (POS) terminal comprising:
one or more input mechanisms;
a cash drawer operable by a solenoid; and
a system comprising:
a controller circuit;
a voltage regulator;
a switch to receive input from the controller circuit and the voltage regulator;
one or more processors; and
one or more memory resources storing a basic input/output system (BIOS), the one or more memory resources further storing instructions that, when executed by the one or more processors, cause the system to:
detect, from the one or more input mechanisms, a user input to unlock the cash drawer; and
in response to the user input, (i) cause the voltage regulator to generate and transmit a voltage signal, having a predetermined voltage, to the switch, and (ii) run the BIOS to assert the controller circuit to generate and transmit a pulse signal, having a configurable duration, to the switch, causing the switch to transmit the voltage signal to the solenoid for the configurable duration;
wherein the transmitted voltage signal causes the solenoid to change states and unlock the cash drawer; and
wherein the configurable duration of the pulse signal is configurable via a displayable user interface of the BIOS, the user interface providing access to BIOS settings enabling a user to configure or adjust an internal timer to set the configurable duration of the pulse signal.

10. The POS terminal of claim 9 , wherein the controller circuit comprises the internal timer, and wherein the configurable duration of the pulse signal is based, at least in part, on the internal timer.

11. The POS terminal of claim 9 , wherein the pulse signal causes the voltage signal to be transmitted to the solenoid by changing states of the switch coupled to the controller circuit.

12. The POS terminal of claim 9 , wherein the system further comprises a physical interface coupled to the switch, and wherein the cash drawer is coupled to the physical interface.

13. A method of operating a point-of-sale (POS) terminal, the method performed by one or more processors of the POS terminal and comprising:
detecting a user input to unlock a cash drawer coupled to the POS terminal, the cash drawer operable by a solenoid; and
in response to the user input, (i) causing a voltage regulator of the POS terminal to generate and transmit a voltage signal, having a configurable voltage, to a switch, and (ii) running a basic input/output system (BIOS), stored in a memory resource of the POS terminal, to assert a controller circuit to generate and transmit a pulse signal, having a duration configurable via a graphical user interface of the BIOS, to the switch, causing the switch to transmit the voltage signal to the solenoid for the configurable duration;
wherein the transmitted voltage signal causes the solenoid to change states and unlock the cash drawer.

14. The method of claim 13 , wherein the user input to open the cash drawer is provided by a user via the graphical user interface of the BIOS.

15. The method of claim 13 , wherein the solenoid comprises an electromechanical solenoid.

16. The method of claim 13 , wherein the solenoid comprises a rotary solenoid.

17. The method of claim 14 , wherein the configurable duration of the pulse signal is configurable via the graphical user interface of the BIOS, the graphical user interface providing access to BIOS settings enabling the user to configure or adjust an internal timer, operable on the controller circuit, to set the configurable duration of the pulse signal.

18. The method of claim 17 , wherein the graphical user interface further enables the user to configure or adjust the configurable voltage of the voltage signal.
