Description
- This application is a continuation of and claims priority under 35 U.S.C., §120 U.S. patent application Ser. No. 10/977,480, filed Oct. 29, 2004 and entitled PAD COMPUTER, the entire contents of which are incorporated herein by reference, which claims priority from U.S. Provisional Patent Application No. 60/515,753, filed Oct. 30, 2003, which is incorporated herein by reference.
- Computers can come in a variety of sizes and configurations, from large desktop units to laptops to smaller sizes. Personal digital assistants (PDAs) and other smaller devices also can have much of the functionality of computers. Computers have various configurations of screens, keys, and other features.
- The computers described here can be smaller than a currently conventional laptop computers, but can have about any size. They can also include many useful features, including a high-resolution color display, built-in keypad, wireless LAN connection, hi-fidelity audio system, and a multi-gigabyte disk drive. The keypad can be a split keypad on opposite sides of a screen formed in a top face of a computer. The computer can also have various other controls and features, including function keys, scroll wheel, game D-pad, stylus, and fingerprint reader. Speakers can also be built into the top face.
- The computers as described can be self-contained and could be a user's only computer, usable for processes such as for researching and writing school assignments, drawing, painting, online shopping, reading news, chatting, e-mail, listening to music, and watching movies.
-
FIG. 1 is a perspective view of a computer. -
FIG. 2 is a plan view of the computer ofFIG. 1 . -
FIGS. 3 and 4 are close-up views of portions of the computer shown inFIGS. 1 and 2 . - Referring to
FIG. 1 , acomputer 10 has ahousing 12 withbumpers LCD screen 18 formed in the top face.LCD screen 18 can be provided in portrait orientation as shown here and in application Ser. No. 29/192,829, filed Oct. 30, 2003, or in a landscape orientation, as also shown in application Ser. No. 29/209,316, filed Jul. 14, 2004 (both of these design patent applications are incorporated herein by reference). The screen has a cold cathode fluorescent lamp (CCFL) backlight with an inverter.Screen 18 can be laterally centered in the housing and can extend for most of the vertical dimension of the housing. The screen can be a resistive 4-wire touch screen. The housing can be made of smooth bright-colored plastic and/or metal. - The computer can have a fold-over cover (not shown) to protect the LCD screen. The cover can screw onto the housing but is customer-replaceable. The cover can be made with a user's choice of materials: metal, plastic, rubber, spandex, leather, etc. The cover is convenient to use, ensuring it is used regularly to protect the LCD. Users can have a whole collection of covers that they pop on and off to suit their mood or fashion.
- As also shown in
FIG. 2 , the computer is balanced so it rests easily in the user's hands when using a built-in keyboard or and does not readily tip when using a stand. The keypad is in the top face of the housing and preferably has a full QWERTY keyboard plus function keys. As also shown inFIGS. 2-4 , the keypad can be split to include aleft keypad 20 between a left edge of the screen and a left edge of the housing, and aright keypad 22 between the right edge of the screen and the right edge of the housing, and thus on opposite sides of the screen. Generalpurpose function keys specific function keys - The computer controls can also include a game controller-style direction pad (D-Pad) 36, a
thumbwheel 38 that is easily accessible when using the built-in keyboard, and can include a fingerprint reader 40 (including, for example, a thumbprint), or may have some other biological detector for detecting the presence of a particular user to allow use of the computer by that user. Such a detector is not necessary, and other protections, such as password protection, could be used. The computer could also be shared among multiple users, such as in an educational environment, in which case the computer can sense the user biologically and automatically configure itself for the particular sensed user, or configure in one of a number of ways for one of a group of users. - The computer housing can be designed to be water and grit resistant, meaning that an occasional splash of water or soft drink will not seep into the case and ruin the electronics. Using it at the beach or pool is possible, though it may not necessarily survive a full dunking. The LCD and keyboard have basic rubber gaskets and any external openings for jacks are covered with rubber plugs.
- While a keypad and touch screen are preferably built-in, an optional full-size keyboard and mouse can connect wirelessly via Bluetooth technology. Internet and LAN connectivity is preferably wireless via built-in WiFi (802.11b). Printers can also be connected wirelessly via either Bluetooth or WiFi. For compatibility with existing wired devices, such as cameras, scanners, and printers, a USB port (e.g., 1.1) is also provided.
- The top face of the housing can also include one or more covers for
speakers card slot 46 and a headphone jack 48. - A
stylus holder 50 for holding a stylus can also be provided in the top face of the computer. - The computer preferably does not have any external antennas or other dangling parts that can break off if treated roughly.
- One set of exemplary dimensions is approximately 10″ in length, 9.3″ wide, and less than 1″ thick, e.g., about 0.8″ thick. It is designed to be durable, and able to survive being dropped on the floor, tossed in a backpack, and splashed. Other dimensions are possible, but it is preferably smaller than a typical current laptop, but larger than a PDA.
- The computer preferably runs on the Linux operating system and Java, and should be reliable and secure. The Java run-time environment is designed to allow users to download and run dozens of programs.
- The environment should also be private—the information on the computer can be encrypted and it is preferably unlocked only when a test is met, such as the owner's thumbprint.
- The computer is designed to use low-cost, low-power components. Since long battery life (at least 8 hours) is desired, the system is designed to power on and off components as needed.
- The system can include a WiFi/802.11 b PC card with housing-mounted diversity antennas, Bluetooth wireless radio chip with embedded ROM connected via dedicated interface, a shock-mounted PC card disk drive, audio CODEC, audio amp, built-in stereo speakers and microphone, mini stereo headphone, and microphone jacks (some of which are shown above).
- Further components that can be added or provided include FM Radio, WiFi wireless LAN chipset, disk drive, digital camera module and connector with custom FPGA controller, built-in or snap-in power adapter/charger, compact Flash Card slot, V.90 modem and RJ-11 jack, analog joystick, and additional function buttons (e.g., more game controller buttons).
- A slot-loading CD-RW/DVD that optionally snaps on the back of the computer can be provided. The CD/DVD backpack can be added or removed without powering down the computer, so it should use a plug & play interface, such as USB. The backpack may also require an additional internal battery to ensure at least 2 hours of DVD playing time.
- The angle and curve of the housing and the angle of the keypads relative to the edges of the housing are useful for the feel and ergonomics of the computer, in addition to providing an attractive and ornamental appearance. The lateral sides are preferable bowed outwardly (concave) and the top and bottom sides are bowed inwardly (convex). By splitting the keypad and locating it in the upper half of the housing at the proper position in the curve, the computer remains balanced in the user's hands while the user is typing, scrolling, or gaming.
- The computer is preferably built from a two-piece injection molded and machined plastic housing. The two front side panels are covered with customer-replaceable and customizable faceplates. The edges of the housing can include soft elastomeric plastic grips that also protect the edges of the housing. The LCD is also protected with an elastomeric bezel.
- Many details are provided but numerous modifications can be made. It is expected that improvements will be made with future hardware as it becomes available. In addition, not all the components set out above are needed; for example, the keyboard could have fewer keys, certain interfaces and ports could be omitted, and other changes could be made that could add features, or reduce features and cost.
