Detailed Description
FIG. 1A is a side view of a pen cap according to one embodiment of the present invention. FIG. 1B is a top view of a pen cap according to an embodiment of the present invention. FIG. 1C is an expanded view of a soft inner ring according to an embodiment of the present invention.
Referring to fig. 1A and 1B, the pen cap 100 includes a hard outer ring 110 and a soft inner ring 120. The soft inner ring 120 contacts the hard outer ring 110 and is disposed within the hard outer ring 110. The space 170 within the soft inner ring 120 can accommodate a conventional pen. The rigid outer ring 110 is formed, for example, of plastic or other rigid material. The soft inner ring 120 is formed of, for example, Polyurethane (PU) material, soft fabric, or other soft compressible material. A plurality of pressure sensors 130 may be disposed within the soft inner ring 120 and coupled to the processing circuitry 150. As can be seen from the top view of the pen cap in FIG. 1B and the expanded view of the soft inner ring in FIG. 1C, the pen cap 110 has nine pressure sensors 130 disposed around the pen cap 110. Three pressure sensors 130 (i.e., a1, a2, a3) are disposed at a lower portion (i.e., near the tip end) of the cap 110. Three pressure sensors 130 (i.e., b1, b2, b3) are disposed at the middle section of the pen cap 110. Three pressure sensors 130 (i.e., c1, c2, c3) are provided at the upper section of the pen cap 110 (i.e., away from the pen tip end). In another embodiment, the number of pressure sensors 130 can be increased or decreased, for example, four pressure sensors 130 are disposed on each of the upper, middle and lower sections of the pen cap 110, or the pressure sensors 130 are disposed only on the upper and lower sections of the pen cap 110.
When the pressure sensing values of the pressure sensors 130 are transmitted to the processing circuit 150, the processing circuit 150 can determine whether the pen cap 110 is in the pen-out mode, the pen mode or the writing mode according to the pressure sensing values. The above modes are described in detail below. The battery 160 may be coupled to the processing circuit 150 and the pressure sensor 130 for power. The first ring electrode 141 (e.g., Tx1) and the second ring electrode 142 (e.g., Tx2) can provide an active pen function, i.e., touch sensing between the pen cap 110 and the touch panel, and enable the active pen to have a tilt (tilt) function. It is noted that, in another embodiment, the processing circuit 150 and the battery 160 can be implemented by a flexible circuit board or a flexible battery, and disposed in the rigid outer ring 110 or the flexible inner ring 120. This saves space occupied by the processing circuit 150 and the battery 160 at the end of the pen.
FIG. 2 is a schematic diagram of a conventional pen with a cap according to an embodiment of the present invention.
Referring to fig. 2 and fig. 1A to 1C, when the pen cap 100 is fitted with a conventional pen, the soft inner ring 120 is compressed from the original inner diameter 201 to the conventional outer diameter 202. That is, the pen cap 100 may be switched from the pen-less mode to the pen mode.
Table one is an example of the pressure sensing values of the nine pressure sensors in the non-pen mode.
Watch 1
a1＝0 a2＝0 a3＝0
b1＝0 b2＝0 b3＝0
c1＝0 c2＝0 c3＝0
Table two is an example of the pressure sensing values of nine pressure sensors with pen mode.
Watch two
a1＝1.1 a2＝1.1 a3＝1.1
b1＝1.2 b2＝1.2 b3＝1.1
c1＝1.2 c2＝1.1 c3＝1.2
As can be seen from the first and second tables, in the pen-less mode, the soft inner ring 120 is not pressed, and therefore the pressure sensing values of the pressure sensor 130 are both 0. When the pen cap 100 is fitted on a conventional pen, the soft inner ring 120 is pressed so that the pressure sensing values of the nine pressure sensors 130 are within a certain range of difference (i.e., 1.1 to 1.2). Therefore, when the pressure sensing values of the pressure sensors 130 are not equal to zero and the difference between the pressure sensing values of any two pressure sensors 130 is smaller than the first pressure threshold (e.g., 0.2), the processing circuit 150 can determine that the pen cap 100 is in the pen mode.
Fig. 3A is a schematic view of a pen cap according to an embodiment of the present invention in a writing mode. Fig. 3B is a schematic diagram of a pen cap according to an embodiment of the present invention in a section a 'B'. Fig. 3C is a schematic diagram of a pen cap according to an embodiment of the invention, shown in section AB.
Referring to fig. 3A to 3C and fig. 1A to 1C, when a user writes, a greater pressure is applied to the soft inner ring 120 of the pen cap 100 at points a' and B. Point a' is near pressure sensor a1 and point B is near pressure sensors c2 and c 3.
Table three is an example of the pressure sensing values of nine pressure sensors in the writing mode.
Watch III
a1＝2.0 a2＝1.2 a3＝1.3
b1＝1.3 b2＝1.3 b3＝1.3
c1＝1.3 c2＝1.8 c3＝1.8
From table three, in the writing mode, the user holds the hard outer ring 110 of the cap 100 and applies force to the writing surface through the tip of the conventional pen. Therefore, the soft inner ring 120 at the point A' of the pen tip is pressed to generate the maximum pressure sensing value 2.0 for the pressure sensor a 1. Meanwhile, the soft inner ring 120 at the point B of the pen tail is also pressed, so that the pressure sensors c2 and c3 generate a larger pressure sensing value of 1.8. Therefore, when the pressure sensing values of the pressure sensors 130 are not equal to zero and the difference between the pressure sensing values of two of the pressure sensors 130 is greater than a second pressure threshold (e.g., 0.5), the processing circuit 150 can determine that the pen cap 100 is in the writing mode. In the writing mode, the pen cap 100 can generate electronic handwriting of the active pen through the first ring electrode 141 and the second ring electrode 142.
FIG. 4 is a flow chart of a method of using a pen cap according to an embodiment of the invention.
Referring to fig. 4, in step S401, a plurality of first pressure sensors and a plurality of second pressure sensors are disposed in a soft inner ring of a hard outer ring of a pen cap, where a distance between the first pressure sensors and a first end of the pen cap is smaller than a predetermined distance and a distance between the second pressure sensors and the first end is greater than the predetermined distance.
In step S402, when the pressure sensing values of the pressure sensors are all equal to zero, the pen cap is in the pen-less mode.
In step S403, when the pressure sensing values of the pressure sensors are not equal to zero and the difference between the pressure sensing values of any two pressure sensors is smaller than the first pressure threshold, the pen cap is in the pen mode.
In step S404, when the pressure sensing values of the pressure sensors are not equal to zero and the difference between the pressure sensing values of the two pressure sensors is greater than the second pressure threshold, the pen cap is in the writing mode.
In summary, the pen cap and the use method of the pen cap of the present invention have the soft inner ring disposed in the hard outer ring of the pen cap. The soft inner ring comprises a plurality of pressure sensors which are different from the first end of the pen cap in distance. The processing circuit can judge whether the pen cap is in a pen-free mode, a pen mode or a writing mode according to the pressure sensing value of the pressure sensor.
Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above embodiments, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention.
