Management protocols
Applications

4. 11.2 History Palm’s mission
Create a handheld device that was extension of desktop
Allow users to enter small bits of info when away from desk
Extend the PC work environment
Insufficient infrastructure and funding in early 90s
1995, US Robotics bought Palm and funded first line of products
Organizational features
Allowed synchronization with PC

5. 11.2 History 1997, 3Com bought US Robotics, more funding to Palm
Palm’s success allowed Palm to spin-off as independent company
Palm went public in March 2000
Now leader in manufacturing handheld devices
Owns 71% of market

9. 11.3.1 Controls and Body Design

10. DragonBall Processor
All Palm OS devices use a form of the DragonBall CPU
The Motorolla DragonBall CPU
Controls device before operating system takes over
Supports liquid crystalline display (LCD), real-time clock (RTC), universal receiver and transmitter and infrared standard (IrDA)
Variations: CPU speed, technologies supported and degree of support

11. 11.4 Palm OS
Operating system: device’s control and foundation software
The Palm operating system: controls many features:
Operation modes
Memory types
Applications
Performance features

12. Modes of Operation
Modes of Operation: describe current state of device
Sleep mode: device’s “off” state
Minimum power state, but still electricity (else memory lost)
Real-time clock is only thing running
Doze mode:
Intermediate power state
Displays available, but no input or active use
While viewing information
Active mode:
Maximum power state
Applications running, input and processing
While downloading, synchronizing and beaming information

13. 11.4.1 Modes of Operation PC modes
Screen saver mode: inactive desktop, power reduced
Energy saver mode: screen powered off, saves energy
PC can be completely powered down without losing memory/information

15. Memory
Memory: storage area for information, applications, processes and instructions
Random Access Memory (RAM) in the Palm
Used for permanent memory
Erased if power lost
RAM in the PC
Stores information only when PC in use, erased when powered down
Only hard drive memory is permanent
Megabytes: measurement of memory units
Palm offers 2-16MB

16. 11.4.3 Running Applications Smaller memory means smaller applications
Palm cannot multitask
User interface application shell (UIAS): manages and prioritizes Palm applications sent to OS
Launch codes: commands that tell OS to start and display an application
Resources
Separately stored packages of codes and data that combine to form an application

17. 11.4.3 Running Applications Synchronization
Achieved through USB cradle/sync port (hardware)
Conduit programs: cross-check and update PC and Palm to display identical information
Most Palm’s operate under PalmOS V3.0 or higher
V4.0 supports multimedia, streaming video and audio, and phone capabilities

18. Security
Password-protection: machine unusable until correct password entered
Virus protection: McAfee and Symantec provide small anti-virus packages
When business and personal information becomes more commonly transferred on Palm devices, security will be of increased importance

19. Security
Palm password protection screens. User enters the password and assigns it to the
device for security protection. Once the machine is locked, it cannot be used again
until a user enters the correct password. (Courtesy of Palm, Inc.)

20. 11.4.5 Graffiti® Entering information
Digital keyboard: stylus selects letters on digital keyboard
Graffiti: handwriting recognition application
Using graffiti
Special shorthand characters when writing appear normal on screen
Portable keyboard accessory also available

21. Graffiti®
Example of Graffiti® characters used for entering data into a Palm device.

22. 11.4.6 Other Palm OS-based Devices
Hybrid: many wireless device features in one
Visor
Visorphone attaches to Visor Handspring (uses Palm-OS)
Telephone system linked to Handspring’s address book
Visorphone can access internet with additional software
Kyocera smart phone
Tri-mode technology: operates in CDMA, PCS and analog networks
Uses Palm platform
PDA features: address book initiates calls, etc…
Can communicate through infrared
