Abstract
An electronic stylus and a tracker. The tracker comprises an outer casing body (132), a tracking circuit (40), a data interface (46), an ultrasonic wave receiver (36), and an infrared ray receiver (38). An end of the outer casing body (132) extends to form an accommodating cavity (50) for inserting an electronic stylus (110). The electronic stylus (110) comprises a casing body (112), a writing tool (14), a signal transmitter (16), and a power supply (18). A nib (24) of the writing tool (14) extends out of the casing body (112). The signal transmitter (16) is disposed at a position near the nib (24). By means of the technical solution of the present invention, the electronic stylus and the tracker can be combined at will and are convenient to store and carry, and the electronic stylus and the tracker that form a complete set is not easily disordered, thereby bringing convenience to a user.

Abstract
The present invention relates to a virtual input method and system, comprising an information reception end for acquiring inputted information, an operation end for input operations, an operation surface on the operation end for inputting, and a control unit for input control. The present invention defines input areas in a virtual input system, assigns one type of input information to each input area, and thereby directly electronifying the input information. The present invention enhances the conventional ultrasonic wave input method, and completes, using a simple method, the electronic process of tracing handwriting using an ultrasonic input method.

Abstract
Disclosed is an ultrasonic wave receiving window (1), which comprises an ultrasonic wave receiving port (11) and a shielding portion (12) for shielding ultrasonic waves; the receiving port (11) has an area of 0.24 a2 to 0.6 a2, where a is the wavelength of an ultrasonic wave, and the receiving port (11) is exactly opposite to an ultrasonic wave receiver (31). The ultrasonic wave receiving window (1) functions to protect the ultrasonic wave receiver (31) from being damaged. By providing an ultrasonic wave receiving window (1) at the front end of the ultrasonic wave receiver (31), the present invention can filter some noise and echoes produced by the ultrasonic wave, improving the reception result of the ultrasonic wave. By using the ultrasonic wave receiving window (1), the ultrasonic wave input device of the present invention makes the input paths more continuous and effectively prevents the production of "fly lines", improving the input result.
A rangefinder, for locating an object moving parallel to a planar surface, is rigidly attached to a carrier that is pivotably movable between an obverse position and a reverse position relative to a planar surface. Preferably, an orienting mechanism is provided for determining which position, obverse or reverse, the carrier and rangefϊnder are in. Preferably, a pivot, for pivoting the carrier and the rangefinder between the two positions, is rigidly attached either to the plane surface or to an attachment mechanism for reversibly attaching the carrier to the planar surface.
Various electronic pen devices are disclosed herein. In one embodiment, an electronic pen with an improved ultrasound transducer (i.e. transmitter or receiver) is provided. In one embodiment an electronic pen with an improved 'pen up/pen down' detector is provided. In one embodiment, an electronic pen with an improved structure for transmitting infrared light is provided. In one embodiment an improved electronic pen that may be operated in pen mode or mouse mode is provided.
A system (5) for tracking the position of a digital (100) pen including a (i) pen-fixed ultrasound device (210) (i.e. transmitter or receiver) and (ii) a plurality of writing-surface fixed ultrasound devices (150) (i.e. transmitters or receivers) is disclosed. In some embodiments, a measurement is made of the time that it takes for ultra-sound to travel between the pen-fixed ultrasound device (210) and the writing-surface fixed ultrasound devices (150) via a path that includes a writing surface sub-path (170) between the 'given point' (175) on the writing surface and the writing-surface fixed ultrasound devices (150). In some embodiments, the position of the digital pen (100) or a component thereof (for example, pen-fixed ultrasound device (210)) may be determined in accordance with (i) the aforementioned measured times of ultra-sound travel; and (ii) the speed of sound within the writing surface (140). Related methods for tracking the position of the digital pen (100) are disclosed. Related methods for manufacturing any presently-disclosed system are also provided. Furthermore, apparatus and methods for transmitting ultra-sound from a pen-fixed ultrasound transmitter (210), and for detecting ultra-sound that propagates in a board or writing surface (140) are disclosed.
