Abstract
An information handling system implemented as a convertible notebook may include a first assembly, a second assembly hingedly coupled to the first assembly, a magnet housed in the first assembly, a giant magnetoresistance sensor housed in the second assembly, a Hall effect sensor housed in the second assembly, and a management controller communicatively coupled to the giant magnetoresistance sensor and the Hall effect sensor, and configured to, based on a first signal received from the giant magnetoresistance sensor and a second signal received from the Hall effect sensor, determine a position of the first assembly relative to the second assembly.
Claims18
An information handling system implemented as a convertible notebook, comprising:
- a first assembly;
- a second assembly hingedly coupled to the first assembly;
- a magnet housed in the first assembly;
- a giant magnetoresistance sensor housed in the second assembly;
- a Hall effect sensor housed in the second assembly;
- and
- a management controller communicatively coupled to the giant magnetoresistance sensor and the Hall effect sensor, and configured to, based on a first signal received from the giant magnetoresistance sensor and a second signal received from the Hall effect sensor, determine a position of the first assembly relative to the second assembly.
A method, for use in an information handling system implemented as a convertible notebook having a first assembly with a magnet housed therein and a second assembly hingedly coupled to the first assembly, the method comprising:
- receiving a first signal from a giant magnetoresistance sensor housed in the second assembly;
- receiving a second signal from a Hall effect sensor housed in the second assembly;
- and
- based on the first signal and the second signal, determining a position of the first assembly relative to the second assembly.
An article of manufacture, comprising;
- a non-transitory computer readable medium;
- and
- computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in an information handling system implemented as a convertible notebook having a first assembly with a magnet housed therein and a second assembly hingedly coupled to the first assembly:
- receive a first signal from a giant magnetoresistance sensor housed in the second assembly;
- receive a second signal from a Hall effect sensor housed in the second assembly;
- and
- based on the first signal and the second signal, determine a position of the first assembly relative to the second assembly.
