Device Interface

Compupen Technology (Device Interface)

Pen2Net’s devices feature the Bluetooth wireless application link for maximum portability and adaptability. With Bluetooth technology, a tiny Bluetooth microchip, incorporating a radio transceiver, is built into digital devices. The radio transceiver initiates connections instantly and 100% wirelessly. Bluetooth allows for non-line of sight transmission (unlike IrDA-dependent devices like TV remote controls) and for an error-free, secure data stream.

Bluetooth simplifies access to data networks and other devices, including PDA’s, laptop PC’s, digital mobile telephones, and eventually, wireless pager/e-mail information devices.

Bluetooth is designed to be fully functional, even in the noisiest radio environments. Pen2Net expects Bluetooth’s error-resistance to be critical in hospital and scientific research environments; the Bluetooth data stream is also encrypted (56-bit) and authenticated for the user’s privacy.

Pen2Net Device Connectivity (Bluetooth-enabled)

All Pen2Net devices feature Bluetooth and by design connect directly to Bluetooth-enabled mobile telephones. Compupens connect instanty to mobile telephones, even without line-of-sight connections. The ability to connect instantly and effortlessly to a mobile telephone grants Compupen the ability to function worldwide without the need for a laptop PC!

On MediPen and SciPen, the Bluetooth connectivity expands to allow hospital or research facilities a “central hub” receiver to which all MediPen and SciPen devices within ~30ft. can connect. The Bluetooth central receiver can be placed in pharmacy settings, patient facilities, research laboratories, and then interfaced via TCP/IP to existing LAN or WANs. From the LAN, encrypted connections to Pen2Net servers allow full processing and formatting of records, manuscripts, prescriptions, and any other application suitable for handwritten input.

Connectivity to PCS Telephone / Bluetooth-enabled PDA

All Pen2Net devices connect via Bluetooth to nearby Bluetooth-ready PDA devices. Pen2Net is currently developing software for host communications and TCP/IP data forwarding on small-formed PDAs and expects client software suitable for interconnect and handwriting forwarding to be available upon product release. The host application will manage users’ handwriting files on Compupen, provide a full log of authenticated transactions on Medi- and SciPens, and serve as the interface to the Pen2Net portal for visualization on a desktop PC.

To fully fulfill it’s promise of being a “write-anywhere” device, all Pen2Net products will communicate with select Bluetooth-enabled mobile telephones for data transmission and forwarding to Pen2Net servers. 24-hour data downlink capabilities supported by Pen2Net Internet portals allow any written document can be forwarded to a desktop PC from anywhere a PCS telephone operates at any time!

Data Security and Encryption

All Pen2Net offerings give the user confidence and insitutitions the peace of mind of 128-bit encryption and compliance with the Mobile Electronic Transaction Initiative protocols. The MeT initiative is an industry specification for encrypted wireless communications and fulfills the middle encryption layer of the Pen2Net transmission stream.

Beginning with the 56-bit encryption system inherent to Bluetooth, MeT-compliant Compupens guarantee encrypted data transmission to the Pen2Net data processing center. We envision full encryption as being critical for the patient records and prescription capabilities of Medipen as well as for all sensitive applications written with SciPen. While not required for the consumer market, full encryption is nonetheless included in Compupen to allow e-commerce transactions and peace of mind when writing even simple receipts and personal notes.
