DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The portable hand held computer terminal and rearranged QWERTY keyboard are shown in one preferred embodiment using a thin display screen 3 with a touch sensitive labeled overlay 7, represented in detail by FIG. 1. The portable hand-held computer terminal 100, shown in FIG. 2, includes a microprocessor 13 for storing operating programs, databases, processing data, storing data, displaying data through a display screen or any needed process.

A battery 4 is used as an internal power source for powering the microprocessor 13, the display screen 3, the touch sensitive display screen 7, the microphone 21 and data storage circuit 12, the external microphone and speaker 22, the optical recording device 10 and visual data storage circuit 9, the antennae 15 and a means for wirelessly transmitting and receiving data 14, connection ports 19 for transmitting and receiving data or to power or use a peripheral device.

The portable hand held computer terminal and keyboard 100 uses a standard plug type connection 24 for powering, from any standard electrical outlet, the microprocessor 13, all peripheral devices connected 19 to the portable hand held computer terminal 100 and for charging the battery 4.

The alphanumeric QWERTY keyboard has been rearranged to allow for entering data on the keyboard 2 using only one finger. Every character and function is assigned a separate sensor. The standard QWERTY keyboard uses the 1 through 9 keys and 0 key to produce numbers and allows shifting to produce ten extra symbols on the 1 through 9 keys and 0 key. When typing with only one finger, it is very difficult to shift and press a second key to produce a data character. The 1 through 9 keys and 0 key produce ten numbers and ten symbols. The standard QWERTY keyboard also has eleven symbol keys to produce common symbols and punctuation and shifts into a second set of symbols and punctuation. The standard QWERTY keyboard has 21 keys, used to produce 42 symbols and punctuation marks. The portable hand held computer terminal and keyboard 100 uses 42 sensors to produce 42 symbols and punctuation marks.

As shown in FIG. 1 semicolon sensor [ ; ] and colon sensor [ : ] are located on the same row next to each other. The apostrophe sensor [ ' ] and quote sensor [ " ] are located on the same row next to each other. The question mark sensor [ ? ]and apostrophe sensor [ ! ]are located on the same row next to each other. The slash sensor [ / ], backslash sensor [ \ ] and vertical line sensor [ | ]are located on the same column next to each other. The function sensor [Fn], alternate function sensor [Alt] and control function sensor [Ctrl] are adjacent to each other.

The degree symbol [ ̊ ] sensor has been added as extra key and symbol. The mathematical function sensors: plus [ + ] sensor, minus [ - ] sensor, multiplication [ × ] sensor, division [ ÷ ] sensor, equals [ = ] sensor and percent [ % ] sensor are preferably located on the same row next to each other. Standard QWERTY keyboards do not have the multiplication [ × ] sensor as a mathematical function or the division [ ÷ ] sensor as a mathematical function sensor. Left containment character sensors; the left brace symbol [ { ] and sensor, the left bracket symbol [ [ ] and sensor, the left parenthesis [ ( ] and the left less than symbol [ < ] and sensor are located on sensors positioned preferably together on the left side of the alphanumeric keyboard and right containment character sensors; the right greater than symbol [ > ] and sensor, the right parenthesis symbol [ ) ] and sensor, the right bracket symbol [ ] ] and sensor, the right brace symbol [ } ] and sensor, are located on sensors positioned preferably on the right side of the alphanumeric keyboard 2.

The alphanumeric keyboard 2 has the backspace function sensor [BkSp] located on the left side of the space bar and the delete function sensor [Del] located on the right of said space bar. Four sensors for moving a cursor in four different directions on the display screen are shown in FIG. 1, unlike standard computer keyboards which use the down key positioned between the left cursor key and the right cursor key. There are also a plurality of control keys for operating in a plurality of modes. There are twelve function keys [F1] through [F12] on the portable hand held computer terminal and keyboard 100, the same as the standard computer keyboard, along with the [Ctrl] key, [Alt] key, [Fn] key, [Caps Lock] key, [Insert] key, [ Home] key, [End] key and [Esc] key.

The space bar is preferably divided into a left space bar and a right space bar. Activating the left space bar and the right space bar simultaneously exits a space bar mode and enters a cursor movement mode. Activating the left space bar moves the cursor to the left and activating the right space bar moves the cursor to the right. Activating the left space bar and the right space bar simultaneously exits the cursor movement mode and returns to the space bar mode.

The carat [ ^ ] sensor is positioned to the left of the alphabetic keyboard spanning the two top rows starting with the [Q] sensor and the [A] sensor. The carat [ ^ ] sensor is never used by the normal computer keyboard user. The portable hand held computer terminal keyboard uses the carat [ ^ ] sensor as a second shift key. When the carat [ ^ ] symbol has to be produced, the keyboard user activates the carat [ ^ ] sensor combined with the shift sensor or Caps lock sensor located next to the carat [ ^ ] sensor.

The alphanumeric keyboard 2 uses a numeric phone keypad arrangement 1, making it easier to enter a phone number. The numeric phone keypad arrangement 1 replaces the 1 through 9 keys and 0 key on alphanumeric QWERTY type keyboards. The symbols on the 1 through 9 keys and 0 key are each produced by an additional separate key. The asterisk sensor [ * ] on the numeric phone keypad arrangement produces the asterisk data character and the pound sensor [ # ] produces the pound data character. The comma sensor [ , ] and the period sensor [ . ] are located on the same row next to each other and are preferably adjacent to the numeric keypad 1.

The portable hand held computer terminal 100 uses a data storage circuit 12 for storing data converted to and from the microprocessor 13, more commonly known in the art as RAM. The internal dimensions of the portable hand held computer terminal dictate size of the RAM and the processing speeds, due to the fact that faster RAM processing speeds require more room.

The portable hand held computer terminal and keyboard 100, which is shown in FIG. 1 in one preferred embodiment, uses a thin display screen 3 with a touch sensitive overlay 7 and a data output circuit 12 for displaying data from the microprocessor 13. The thin display screen 3 can easily be made as a paper thin OLED screen, a liquid crystal display (LCD) or any other similar display technology. The touch sensitive overlay 7 can be either an analog matrix touch sensitive overlay, a digital matrix touch sensitive overlay or any other finger positioning location technology.

A framebuffer is a digital device for computers which stores in the so-called video memory (conformed by an array of Video RAM or similar chips) the digital image to be displayed on the monitor. Driven by software, the CPU or other specialized chips write the appropriate bytes in the video memory to conform the image, which an electronic video generator sends to the monitor. Modern systems encode pixel color values by devoting some bits groupings for each of the RGB separate components. RGB information can be either carried by the pixel bits themselves or in a separate Color Look-Up Table (CLUT) if indexed color graphic modes are used.

The portable hand held computer terminal 100 also includes an internal microphone 21 and audio storage circuit 17 for recording, storing and transmitting audio data, along with a connection for an external microphone and speaker 22 for listening, recording, transmitting and storing audio data. The internal microphone 21, preferably a directional microphone, will work best if it is located on the top of the portable hand held computer terminal 100 or located in a position where the audio input will not be blocked or be able to pick up background noise.

The portable hand held computer terminal 100 also includes an optical recording device 10 and visual data storage circuit 9 for recording, storing and transmitting visual data to the microprocessor 13 . The optical recording device 10 can be a digital camera type device, a closed circuit television type device or any other type of optical recording device. By positioning a second optical recording device facing in the opposite direction of the first optical recording device (180 degrees), the portable hand held computer terminal 100 can record or transmit visual data from the front and back of the user simultaneously. The optical recording device 10 and visual data storage circuit 9 are limited to resolution and frames per second because of the compact size. As technology advances and camera and video technology becomes smaller and faster, the visual data resolution and frames per second recording speed will improve.

The portable hand held computer terminal 100 also includes an antennae 15 and a means for wirelessly transmitting and receiving data to and from an external source 14. The antennae 15 will be preferably located on the surface of the portable hand held computer terminal 100 or embedded internally within the portable hand held computer terminal 100. The antennae 15 must be designed to accommodate the transmitting and receiving frequency of the external source. The transmitting and receiving-frequency will preferably be any 2-way frequency: MTS (Mobile Telephone Service), IMTS (Improved Mobile Telephone Service), AMPS (Advanced Mobile Phone Service), NAMPS (Narrowband Advanced Mobile Phone Service), TDMA (Time Division Multiple Access), CDMA (Code Division Multiple Access), W-CDMA (Wideband Code Division Multiple Access), GSM (Global Systems for Mobile communications), GSM-NA (Global Systems for Mobile communications-North America), PACS (Personal Access Communications Systems), PCS (Personal Communications Services), SMR (Specialized Mobile Radio), ESMR (Enhanced Specialized Mobile Radio) and the like.

The portable hand held computer terminal 100 also includes a plurality of connection ports 19 to connect peripheral devices for transmitting and receiving data. Using the USB port or any integrated port to connect a digital scanner or digital fingerprint reader, law enforcement can have identity conformation at their fingertips. Using the optical recording device 10 to record and transmit an image of a suspect, law enforcement can have almost instantaneous identity conformation. Adding a bar code reader 20 and a means for scanning bar code data from an external source or adding an infrared data port 16 and a means for transmitting and receiving infrared data further increases the usability of the portable hand held computer terminal. Adding any other kind of data port 19 and a means for transmitting and receiving any other type of data also further increases the usability and compatibility of the portable hand held computer terminal 100. The most common standard port for transmitting data is the Universal Serial Port (USB 2.0) data port, but any data transmission port will suffice such as the USB 1.1port, Firewire port, Serial port, Ethernet port, Phone Jack port, S-Video port, HDMI port, wireless connection port or any present or future standard or non-standard communications port.

The common actuation keys on standard computer keyboards have been replaced on the preferred embodiment shown in FIG.1 by a clear touch sensitive screen 7 over a thin and flat display screen 3. Using this technology, one large display screen 3 can easily be programmed to be used as a keyboard 2 and data display screen 3. In another preferred embodiment, using a domed shaped key top configuration on a smaller key type actuation keyboard will increase tactile responsiveness and reduce keystroke errors on the smaller area finger tip touch surfaces. The flat panel display 3 can exit the full display keyboard mode and enter a full display graphics mode or a split screen display mode for viewing optical data or video data.

The portable hand held computer terminal 100 can also use a securing strap(s) attached to the receiving slots 50 on the device’s housing or snug fitting sleeve attached to the bottom of said portable hand held mobile computer 100 to secure the device to an appendage, arm or leg, for portability and ease of use.

Accordingly, another advantage of the present invention is that it provides instant reception or transmission of data, whether it may be binary data, audio data, visual data, etc. through the portable hand held computer terminal and keyboard 100.

Another advantage of the present invention is that it provides improved one finger data entry capabilities using a rearranged QWERTY keyboard arrangement where each data character has its own key or sensor for activation with a finger. Repositioning of specific sensors increases data entry speeds.

A latitude of modification, change, and substitution is intended in the foregoing disclosure, and in some instances, some features of the invention will be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the spirit and scope of the invention herein.
