    摘要: A method of using a sensing device to read coded data is provided. The coded data is arranged in accordance with a layout having mirror and n-fold rotational symmetry about a center of rotation, where n is at least two. The layout includes n identical first sub-layouts rotated 1/n revolutions apart about the center of rotation, and n identical second sub-layouts rotated 1/n revolutions apart about the center of rotation. Each second sub-layout is a reflection of a corresponding one of the first sub-layouts. At least one sub-layout includes rotation-indicating data that distinguishes that sub-layout from at least one other sub-layout and reflection-indicating data that distinguishes the reflections of reflected sub-layouts. The method includes sensing a layout using the sensing device, decoding the coded data of the sensed sub-layouts, thereby determining the rotation-indicating data of that sub-layout, and using the rotation-indicating data to interpret the meaning of the coded data.

    摘要: An electronic pen for interacting with a substrate having coded data disposed thereon. The pen comprises: an image sensor for sensing the coded data when the pen is used to interact with the surface; a cartridge having a nib for contacting the surface; a retraction mechanism for slidably moving the cartridge between a retracted position and an extended position; a force sensor cooperating with the retraction mechanism; a processor configured to generate indicating data indicative of the interaction with the substrate; and communication means for communicating the indicating data to a computer system. The image sensor is configured to sense the coded data only when the force sensor detects that the nib is in contact with the substrate.

    摘要: A method for authenticating a pharmaceutical product, the pharmaceutical product being associated with packaging having disposed thereon or therein coded data including a number of coded data portions, each coded data portion being indicative of an identity of the pharmaceutical product and at least part of a digital signature of at least part of the identity. The method includes having a computer system receive indicating data from a sensing device, the sensing device being responsive to sensing of the coded data to generate indicating data at least partially indicative of the identity of the pharmaceutical product and the signature part. The computer system determines the identity at least one determined signature part and uses these to authenticate the pharmaceutical product.
