The note capture device enables a user of any type of image capture device to enjoy the advantages of handwritten notes while having access to the power and flexibility offered by standalone as well as networked computing devices for information storage, retrieval, modification, and communication. The major elements of the note capture device are a housing which contains preferably an electromagnetic digitizer tablet, a small notepad such as a Post-it Notes product or a small paper pad overlying the region of the housing that contains the digitizer tablet, a pen that works in conjunction with the electromagnetic digitizer tablet in the housing, and a wireless or wired connection to a host computer. The notepad has a removable paper writing surface and the pen includes an inked tip of any desired type so that the user experiences a comfortable and familiar feel of pen/pencil on paper as he or she writes on the notepad. The host computer runs an image capture application that captures the pen strokes from the note capture devices and displays them on the screen in a virtual note.

A system, method, and apparatus for communicating information encoded in a bar code format between a mobile communications device and a bar code scanner. Transmission information data is encoded into a bar code format. A signal is generated from the bar code format to simulate a reflection of a scanning beam being moved across a static visual image of the bar code format; and the signal is transmitted as light pulses from the mobile communications device.

A handwriting capture system includes a portable electronic tablet that capture pen strokes made on a standard pad of paper and transfer the captured pen strokes to a digital image capture device such as a personal data assistant or PDA using infrared communications circuitry. The portable electronic tablet is battery powered, and the handwriting capture system includes an infrared activated power switch to extend the useful lifetime of the battery by power up the electronic tablet and infrared communications circuitry only when the system is in use and otherwise by powering off the electronic tablet and much of the communications circuitry, in a manner that is entirely transparent to the user. An IR activity detector remains powered up when the system generally is powered off, and also furnishes power to at least the receiver section of the IR transceiver. When infrared activity occurs, the receiver section indicates that a signal has been received and the IR activity detector responds by signaling a switched power supply to apply normal operating power to the system.

A user is provided with a secure database containing information in diverse categories that relates to the user and that may be represented at least in part in bar code form and communicated with light from a mobile communications device. The diverse information is obtained from any combination of a variety of vendor and governmental computer systems, internet service providers, and communications devices. The user has access to the database using a mobile communications device for displaying, managing, and entering information, and for communicating information in bar code form with light. The user first selects the category that contains the specific item of information, and then selects the specific item of information. The specific item of information then is communicated in bar code form with light from the mobile communications device for scanning by a bar code scanner to obtain the desired good or service.

A system, method, and apparatus for communicating information in a light-based signal utilizing a fob device is disclosed. One method disclosed includes encoding transmission information data into a bar code format; generating a signal from the bar code format to simulate a reflection of a scanning beam being moved across a static visual image of the bar code format; and actively transmitting the signal as light pulses from the fob device. Alternatively, commercial information data may be transmitted to a light-based data receiving device by generating a signal from commercial information data and actively transmitting the signal as light pulses from a fob device. Transmission information data may also be transmitted from a fob device by generating a first signal from a first encoded format; generating a second signal from a second encoded format; transmitting the first signal as light pulses from a fob device; and transmitting the second signal from the fob device.

An accessory for a personal electronic device detects data encoded into light, sound, vibration energy, radio frequency energy, or a combination thereof, and provides the encoded data either to a bar code scanner using light, or to an NFC terminal using NFC protocols. The accessory may be stand-alone, or attachable to the personal electronic device from a suitable housing or integrated into a housing component of the personal electronic device.
