Classification: CPC G | IPC G

Claim 0:
1. An electronic pen comprises:
a primary conductor;
a secondary conductor;
shielding between the primary conductor and the secondary conductor;
two or more orientation capacitors, wherein a first orientation capacitor of the two or more orientation capacitors is substantially parallel to a second orientation capacitor of the two or more orientation capacitors; and
a raw data circuit operable to generate raw data regarding the electronic pen, wherein the raw data circuit includes:
two or more drive-sense circuits coupled to the two or more orientation capacitors, wherein a first drive-sense circuit of the two or more drive-sense circuits is operable to produce a first error signal corresponding to an electrical characteristic of the first orientation capacitor, and wherein a second drive-sense circuit of the two or more drive-sense circuits is operable to produce a second error signal corresponding to an electrical characteristic of the second orientation capacitor; and
one or more subtraction modules, wherein a first subtraction module is operable to subtract the first and second error signal to produce a first difference error signal, wherein the first different error signal is representative of tilt orientation data of the electronic pen with respect to a touch screen.
