Abstract: A notebook computer with a tilting keyboard, which opens a vent when tilted, solves multiple problems and may further materially contribute to countering terrorism. A tilted position of the keyboard allows the vent to open when the notebook lid is open, thereby providing extra cooling capacity during periods of computer use when there is a lessened need for compactness. The vent is it least partially closed when the keyboard is in the stowed position and the lid is closed, thereby reducing the possibility of debris ingestion when air flow needs are reduced and the need for compactness is increased. A security inspection position of the keyboard enables inspection of the inside of the computer, for example as part of a security checkpoint procedure. A negative tilt can reduce wrist strain and repetitive motion injuries for some users. Some embodiments tilt the keyboard automatically in response to the lid opening, and stow the keyboard automatically in response to the lid being closed.

Abstract: Identifying a search engine user's preference for handling quotations, using easily remembered variations for enclosing a quote, simplifies the user interface. An example is enclosing the quote in either single or double quotation marks to indicate search options for the quote. A method of controlling a database search comprises receiving a search string; identifying, within the search string, a pair of phrase indicia such as quotation marks; identifying, between the pair of indicia, a quote string; matching the pair of phrase indicia to one of a plurality of pairs of indicia, wherein first and second ones of the plurality indicate an exact quote search and a modified quote search, respectively; and identifying, responsive to the matching, a request for an exact quote search or a modified quote search. The modified quote search may be a spell corrected search, a word stemmed search, an alternate spelling search, or a translated search.

Abstract: A system is described for storing liquids. The system comprises a cap configured to couple to a container. The cap comprises a base surface configured to provide a base for a coupled container; a flip-open lid positioned to enable access to an interior of a coupled container; a first cavity having a floor defined by a portion of the cap and a sidewall defined by a portion of the cap; and a drainage port sized to enable water to drain from the first cavity. By providing one or more drainage ports for the hollow portions of invertible container caps, the tendency of water to pool and stagnate within the caps can be reduced. This can reduces the growth of harmful mold in showers.

Abstract: Systems and methods are disclosed which enable the establishment of file dates and the absence of tampering, even for documents held in secrecy and those stored in uncontrolled environments, but which does not require trusting a timestamping authority or document archival service. A trusted timestamping authority (TTSA) may be used, but even if the TTSA loses credibility or a challenger refuses to acknowledge the validity of a timestamp, a date for an electronic document may still be established. Systems and methods are disclosed which enable detection of file duplication in large collections of documents, which can improve searching for documents within the large collection.

Abstract: A system is disclosed that enables more rapid entry of text messages in cell phones that use a 12-key keypad. A cursor movement key placed on the side of a device having a numeric keypad enables a user to more quickly and easily and advance the cursor position between letter entries. By placing a cursor movement key in a position that it can be actuated by a different finger than the one in contact with the keypad, a user will be able to type a text message more rapidly when using only a single hand. Providing one or more user-reconfigurable keys on a cellular telephone enables a user to optionally enable a key to perform a desired function or else to be selectively disabled, thereby preventing unintentional input. An embodiment comprises a keypad on a first face and a first cursor movement key on a second face.

Abstract: An embodiment of an audio system comprises a speaker system configured to automatically change a coupling of an audio speaker from a first channel input to a second channel input if an external speaker is coupled to a first output. In embodiments of the invention, the speaker that connects to an audio source, such as an audio card of a personal computer (PC), automatically swaps channels based on the jack into which an external speaker is plugged. Thus, the reconfiguration of the audio system is automatic for the user in some embodiments, requiring nothing more from the user than selecting one of two jacks for use with an external speaker.

Abstract: A system and method enable reliable tamper detection for printed documents. Embodiments determine whether tampering has occurred and, if detected, isolate it to a specific section, such as a single page of a multi-page document. Embodiments render classes of documents tamper evident with cryptographic level security, where such security was previously unavailable, for example, documents printed using common printers without special paper or ink. Embodiments enable proving the date of document content without the need for expensive third party archival, including documents held, since their creation, entirely in secrecy or in untrustworthy environments, such as on easily-altered, publicly-accessible internet sites. Embodiments can extend, by many years, the useful life of currently-trusted integrity verification algorithms, such as hash functions, even when applied to binary executable files.

Abstract: A system and method are disclosed for filtering liquid using a filter platform that is not rigidly affixed to a container containing the liquid to be filtered. The platform may be buoyant so that as liquid flows from one side of the platform, through a filter, and then to the other side of the platform, the platform may move, thus reducing the volume of a container or portion of a container that holds the unfiltered liquid. Alternatively, the platform may be heavier than the liquid to be filtered, may be either set in place on a support structure or else set on top of unfiltered liquid and allowed to sink downward as liquid is filtered. The system may further comprise a flexible membrane that allows two sections of liquid to be separated, even while the platform is moveable.

Abstract: Operating a power saw between a pair of parallel guide rails, which engage opposing sides of saw base plate to constrain the motion of the saw to a straight path, allows for precise cuts. A set of two or more fences allows for multiple cutting options. In some embodiments, non-parallel fences coupled to the guide rails allow for precise cuts at more than just a single angle. In some embodiments, two fences may engage opposing sides of the object to be cut simultaneously, holding the object more securely with respect to the guide rails than would a single fence. A possible clamping force holding the two fences against the object allows the miter guide to remain fixed relative to the object so that the user's hand may be freed for another task, such as holding the saw with both hands.

Abstract: A system and method are described for rendering Compact Discs (CDs) and Digital Video Discs (DVDs) unreadable. Embodiments comprise a frame, a guide for constraining motion of the frame with respect to a disc, and at least one scraping element. Scraping elements may be positioned to damage the disc volume descriptor while the frame moves in a constrained manner relative to the disc. The guide may comprise a spindle which engages the center hole of a disc to hold the frame in a radially-fixed position. A scraping element on the frame damages the disc as the disc rotates relative to the frame. The guide may be integrated, such that the frame comprises a slot through which the disc passes. A scraping element inside the slot damages a disc as it passes through. Embodiments are hand operated, not motorized, and some have no moving parts. Embodiments also function with non-optical media.

Abstract: An apparatus, program product and method detect region boundaries, or edge, of an arbitrary number of pixels in width in a digital image that has coarse resolution, high noise levels and/or significant blur. A self-optimizing kernel generator detects edges of arbitrary thickness. In addition, combining results of multi-resolution edge detection provides significant noise tolerance, such as a 10 dB improvement over conventional techniques. Moreover, the edge detection preserves the precise location of a blurred edge and quantifies image clarity.
