  • Patent number: RE40702
    Abstract: A method for protecting the video memory on a computer system from being illicitly copied. The invention decrypts a previously encrypted image and displays it on the video screen. During the time the image is displayed, the invention protects it from being copied by other running applications. This is accomplished in multithreaded operating systems by first issuing a multithreaded locking primitive to the video memory resource, and then inserting a pending video hardware request that will take precedence over any subsequent video memory access requests. The pending request serves the purpose of destroying the contents of video memory. The pending request is passive in that it does not execute unless a malicious program has removed the video memory lock.

  • Patent number: 7520004
    Abstract: A combined cushion and protective covering for a patient support having a patient-supporting surface comprises a central section having length and width dimensions corresponding substantially to corresponding dimensions of the support surface. Flaps which are unitary with the central section extend from the side edges of the central section a distance beyond the side edges of the support surface. The flaps are thinner than the central section so as to depend from the central section and lie alongside the patient-supporting surface. The central section and the flaps are formed simultaneously by compressing a block of cushioning material in such manner that the central section forms a pad or cushion unitarily joined at its opposite sides to the flaps. During the compression of the block to form the central pad and the flaps the external surfaces of the pad and flaps are heated to an extent sufficient to enable the surfaces of the pad and flaps to form a smooth, moisture proof skin.

  • Patent number: 7520013
    Abstract: A process of extracting liquid from a fabric having a first content of liquid includes the steps of creating a surfactant surface layer including at least one surfactant at an air-liquid interface of the liquid on the fabric, wherein the surface layer has a first surface tension, and adding at least one co-surfactant different from the surfactant. The surfactant and said co-surfactant have substantial chain length compatibility. The co-surfactant reduces the surface tension at the air-liquid interface. The fabric is then subjected to mechanical extraction for a period of time to reduce the liquid content of the fabric from the first content of liquid to a second liquid content.

  • Patent number: 7520020
    Abstract: A cleaning apparatus for cleaning a top of a beverage can. The top of the beverage can to be cleaned is inserted into a can-receiving cavity in the body of the cleaning apparatus, and the top of the can contactingly engages an actuator that opens a valve to a source of pressurized air. First air jets in communication with the air source expel air onto the lip around the top of the can and also onto the lip groove adjacent the lip, thereby cleaning the lip and the lip groove. Second air jets may also clean the top of the beverage can and its mouth. The cleaning is assisted by condensed moisture on the top of the can that is blown by the air expelled from the air jets. Venting ports allow air expelled from the air jets to escape from the can-receiving cavity.

  • Patent number: 7520023
    Abstract: A hinge for connecting a first folding element to a second folding element. The hinge includes a fixing element which comprises a first fixing face by means of which the fixing element is contactingly fixable to the second folding element; a first arm connected to the fixing element so as to be pivotable around a first pivot axis between a first position and a second position; a second arm having a fixing device by which the second arm can be fixed to the second folding element, and is connected to the first arm so as to be pivotable around a second pivot axis extending parallel to the first pivot axis between a first position and a second position. In the first position, the first arm encloses a smallest angle relative to the fixing face and, in the second position, encloses a greatest angle relative to the fixing face.

  • Patent number: 7520024
    Abstract: A hinge assembly could be installed between a panel and a base of an LCD and has a body, an active leaf and two mounting leaves. The body has two sides and two protrusions formed on the two sides respectively. The active leaf has two mounting portions mounted pivotally with the mounting leaves respectively and each mounting portion has a retainer. The mounting leaves are mounted pivotally on the two sides of the body and each mounting leaf has a slide slot with a folding end and an active slot with a latching end. The slide slots hold the protrusions respectively and the active slots hold the retainers. When the protrusions reach the folding ends, the panel and the base is folded into a flat status and encasing or transporting of the LCD is convenient.

  • Patent number: 7520025
    Abstract: A hinge for a notebook extension pad is mounted in an expansion pad of a notebook and has a pivoting assembly, a positioning disk, a limiting stationary leaf, a limiting disk, a pressing assembly and a locking assembly. The expansion pad has a mounting segment and a pad having an external lock. The pivoting assembly is mounted securely on the pad and has a shaft. The positioning disk is mounted around the shaft. The limiting stationary leaf is adjacent to the positioning disk, is mounted rotatably around the shaft and connects with the mounting segment. The limiting disk limits movement of the pad relative to the mounting segment. The pressing assembly provides friction against movement of the hinge. The locking assembly is mounted around the shaft and allows a user to lock the pad at a designed angle to achieve a comfortable height and angle for operating the notebook.

  • Patent number: 7520026
    Abstract: A hinge assembly includes a pintle supporting a first coupling member and a second coupling member. The second coupling member includes two protrusions formed on two opposing faces. Two position limiting members simultaneously abut against the protrusions respectively when the hinge assembly is fully opened. A biasing means include a plurality of resilient members that provides non-continuous contact with the pintle.
