• A fast, efficient and platform independent way to deliver the experience of a software application without downloading the code. Instead, a thin "droplet" on the client acts to display a user interface controlled by a fat application on a server- only screen information is sent down the wire, leaving the business logic and maintenance headaches on the server. Droplets can be used to deliver everything from weather and stock reports (no browser required), to instant messages, email, work flow, payroll and database access.

• Network servers are often overloaded by traffic bursts or time-of-day swells. Typically, more servers are added in a "server farm" to accommodate the load, with some kind of local area network to spread the traffic across the farm. This patent describes an alternative solution, where the server, detecting an imminent overload condition, tells the requesting machine to redirect all future requests to free server which could be located anywhere on the Internet. In addition, the same technique can be used to redirect traffic depending on other business needs- for example, a high priority customer is redirected to a low traffic server, while all others contend for limited resources on the congested server.

• A personal digital assistant (PDA) receives and executes both encrypted and unencrypted programs. Encrypted programs are fairly secure from virus infection, while unencrypted programs are not. To prevent  contamination of the PDA with infected encrypted programs, only those encrypted programs that are keyed to the individual PDA's unique device  identifier can be decrypted and executed by that PDA. To prevent  non-secure programs from corrupting secure programs and their data, programs that were received unencrypted are prevented from modifying programs that were received encrypted as well as data generated by their execution. When a user suspects a virus infection, the user pushes  a special button on the PDA that prevents execution of programs that were received unencrypted and hence are suspected of being infected,  while allowing continued execution of programs that were received encrypted and hence are presumed to be secure. One idea generated from the early smartphone "Airwriter" project"

• This phone is designed to attach to the serial port of a PC, so it can access the PC's (PIM) directory, exchange caller-ID information, auto dial, etc. The phone works even when the PC is off, and stores recent call records for later, automatic updates. A one person PBX/call center.

• In a pen-based or touch-screen computer, the password to unlock the machine is a series of touch sensitive invisible sites hidden under a displayed image. The original patent behind Windows Visual password login.

• A graphics tablet for a PDA or computer, using capacitance to detect the position of the pen. Low cost, low power and high resolution.

• A special hinge for a laptop computer with pen input. The display position can be interchanged with the keyboard by rotating the hinge, yet both the keyboard and display images remain vertical.

• An read/writable optical disk media, using laser induced phase changes to create index of refraction variations, which are read out as information bits.
