Abstract
A angle detection system, includes a first member pivotally coupled to a second member. An optical cable connecting an optical transmitter provided on the first member and an optical receiver provided on the second member is used by an angle detection engine to determine signal loss of an optical signal provided by the optical transmitter through the optical cable to the optical receiver. The angle detection engine then determines, based on the signal loss, a first angle of the second member relative to the first member. The angle detection engine then performs an instruction based on the first angle.
Claims20
A angle detection system, comprising:
- a first member;
- a second member pivotally coupled to the first member;
- an optical cable connecting an optical transmitter provided on the first member and an optical receiver provided on the second member;
- and
- an angle detection engine that is configured to:
- determine signal loss of an optical signal provided by the optical transmitter through the optical cable to the optical receiver;
- determine, based on the signal loss, a first angle of the second member relative to the first member;
- and
- perform, based on the first angle, an instruction.
The angle detection system of claim, further comprising:
- a use sensor coupled to the angle detection engine, wherein the angle detection engine is configured to renormalize a bend angle lookup table that stores associations of signal loss to a respective angle of the first member relative to the second member in response to the use sensor providing a standby signal to the angle detection engine when the first member and the second member are positioned in a closed configuration.
An information handling system (IHS), comprising:
- a display chassis that houses a display device;
- a base chassis that houses a processing system;
- an optical cable connecting each of the display device and the processing system;
- and
- a memory system that includes instruction that, when executed by the processing system, causes the processing system to provide an angle detection engine that is configured to:
- determine signal loss of an optical signal provided by the processing system through the optical cable to the display device;
- determine, based on the signal loss, a first angle of the display chassis relative to the base chassis;
- and
- perform, based on the first angle, an instruction.
A method for determining an angle, comprising:
- determining, by a processing system, signal loss of an optical signal provided through an optical cable that is coupled to a first member and a second member, wherein the first member is pivotally coupled to the second member;
- determining, by the processing system and based on the signal loss, a first angle of the second member relative to the first member;
- and
- performing, based on the first angle, an instruction.
