Abstract: The invention, in one embodiment, is a method for entering data into a computer. The method includes anchoring an electrical cord connecting a peripheral input device to the computer, positioning the peripheral input device, and retracting slack in the electrical cord as the peripheral input device is positioned.

Abstract: In one embodiment of the invention, a hot spot is normally centered in an area of contact between a user's finger and a touch screen to position the hot spot on an icon or other feature thereby selecting a program or function corresponding to the icon or feature. When the contact area is near an edge, the hot spot is offset toward the edge so that it coincides more closely to the center of the users finger, thus allowing an icon or other feature adjacent the edge of the screen to be more easily selected. In another embodiment, a cursor is displayed on a touch screen at a location that is offset from the contact area between a finger and the screen. The cursor, which is used as the hot spot of the computer, is normally offset above the contact area except when the contact area is close to the bottom of the screen.

Abstract: An expandable keyboard with at least one keyboard sections stored in a nested manner inside a default keyboard such that the at least one keyboard sections can be extended in a telescoping manner from a housing of the default keyboard. The default keyboard comprises all the necessary keys to operate the computer so that the computer can be used even when the at least one keyboard sections is in a stored position. The expandable keyboard disclosed is particularly desirable for a portable computer in that it offers users a larger keyboard area comprising a more user friendly keypad layout yet does not add to the computer's thickness or lateral dimension so the computer remains easily portable.

Abstract: A method and apparatus for automatically customizing a vendor's web site, based on a web site customer's previous location or terms used in a search by the customer, to provide incentives for the customer to remain on that vendor's web site and purchase goods or services from that vendor is disclosed. When a customer lands on a vendor's web site, the customer's web browser reports the referring Universal Resource Locator (URL) to the vendor's web site. The URL is parsed and examined by the vendor's web site to determine the web site the customer previously was visiting or, if directed to the vendor's web site by a search engine, the terms used by the customer for the search. The terms included in the referring URL are compared with terms previously stored in a database.

Abstract: A cordless mouse with a transmission port for transmitting light signals downwardly into a mouse pad. The mouse pad includes a lower section and an upper section. The upper section is made of a LCD backlighting material which is arranged to direct the signals toward a light pipe on a side of the upper section. A receiver in communication with the light pipe receives the light signals and transmits them to a computer.

Abstract: A snap-on keyboard configured to operate with a computer. The keyboard comprises a platform having a plurality of surfaces, and configured to house a plurality of components. The keyboard further comprises of a set of keys attached to one of the plurality of surfaces of the platform. The keyboard further comprises a connector attached to at least a portion of one of the plurality of surfaces of the platform. The connector is configured to automatically connect to a receiving connector attached to the computer in response to a force exerted downwardly from the platform to the computer.

Abstract: A system for distinguishing photocopied or laser-printed documents from original documents produced by offset printing, handwriting, or typewriting. The system scans a document at low-resolution and at high-resolution to produce a low-resolution and a high-resolution matrix representation of the presence or absence of ink or toner at discrete locations on the surface of the document. Printed regions detected by the system at low-resolution are used to mask regions of the high-resolution matrix representation from the analysis. The remaining unmasked regions of the high-resolution matrix representation are analyzed by the system to detect discrete microdots uniformly distributed within those regions. The presence of microdots on the surface of the document indicates that the document was produced as a photocopied or a laser-printed duplicate.

Abstract: A computer pointer is disclosed comprised of a housing having an aperture and a ball rollably mounted within the housing so that a portion of the ball is accessible through the aperture in the housing so that force can be exerted on the ball through the aperture to induce the ball to rotate within the housing. The pointer is further comprised of at least one rotating position member having an outer surface, the at least one rotating position member being mounted within the housing and frictionally engaged on a first side with the ball so that rolling motion of the ball results in corresponding rotation of the at least one rotating position member.

Abstract: A method to manage power to a device includes receiving a first power-off request signal, initiating a predetermined delay period, and canceling the first power-off request if a second power-off request signal is received before expiration of the predetermined delay period. If a second power-off request signal is not received before expiration of the predetermined delay period, a signal to cause the device to power down may be generated. A device to perform the method and a system including such a power control device are also described.
