Abstract: A method of transmitting an image from a remote server to a portable device and dynamically viewing, by a human observer, the transmitted image on a display of the portable device. On a remote server, a master set of data representative of a graphic image (30) is processed to form a first subset of data representative of a portion of the graphic image. The data is transmitted to the portable device (49) and drawn on the display (34). The user selects a portion of the image to be further expanded and the master database is again processed to form a second subset of data representative of the selected portion of the image. The second subset of data is transmitted to the portable device and drawn (36) on the display.

Abstract: A master authenticator (10) is worn by a user and wirelessly transmits information associated with the user to a remotely located electronic device. The master authenticator contains a sensor (12) to determine or sense whether or not the user is wearing the authenticator, along with a means to allow the user to log (22) in to the master authenticator by performing predefined physical action on the master authenticator. Once the sensor senses that the user is physically coupled to or wearing the device, the user logs in so as to uniquely associate the master authenticator with the user. Once the user is logged in, a transmitter is enabled so that the information can be transmitted to an electronic device in the proximity of the user. When the user ceases to wear the master authenticator by removing it, the log in means de-authorizes further transmissions by the master authenticator due to action of the sensor sensing that the authenticator is no longer on the user.

Abstract: A method for a human user to interactively enter an alphanumeric text message into a multiline display device (12) using a keypad (14) containing a number of keys. On one portion (22) of the display, the alphanumeric text message that the user is entering is displayed. On a second portion (23) of the display, a listing of subsets (24, 25) of alphanumeric symbols is shown, with each subset being mapped to a corresponding key on the keypad. The user selects the subset of alphanumeric symbols containing the one alphanumeric symbol to be entered into the alphanumeric text message and depresses the key that is mapped to the selected subset. In response to this action, the second portion of the display then changes to show the alphanumeric symbols contained in the selected subset, with each alphanumeric symbol mapped to a specific key on the keypad. The user then selects the desired alphanumeric symbol and depresses the proper key.
