  • LOW-POWER PHASE-CHANGE MEMORY TECHNOLOGY WITH INTERFACIAL THERMOELECTRIC HEATING ENHANCEMENT
    Publication number: 20220115590
    Abstract: A low-power phase-change memory (PCM) technology with interfacial thermoelectric heating (TEH) enhancement is provided. Embodiments described herein leverage a substantial, positive thermoelectric coefficient in PCM materials to generate additional heating or cooling at an interface with another material, enabling memory switching with a large reduction in current and power. Interfacial thermoelectric engineering is applied to a PCM cell using a special class of thermoelectric materials with large negative Seebeck coefficients (e.g., bismuth telluride (Bi2Te3), lead telluride (PbTe), lanthanum telluride (La3Te4), indium selenide (InSe), silicon-germanium (Si0.8Ge0.2)) to induce efficient heating at significantly lowered power and current.

  • GRAPHENE-INSERTED PHASE CHANGE MEMORY DEVICE AND METHOD OF FABRICATING THE SAME
    Publication number: 20160276585
    Abstract: Provided is a phase change memory device including a graphene layer inserted between a lower electrode into which heat flows and a phase change material layer, to prevent the heat from being diffused to an outside so as to efficiently transfer the heat to the phase change material layer, and a method of fabricating the phase change memory device. The phase change memory device includes a lower electrode; an insulating layer formed to enclose the lower electrode; a graphene layer formed on the lower electrode; a phase change material layer formed on the graphene layer and the insulating layer; and an upper electrode formed on the phase change material layer. Since a phase of the phase change material layer is changed at a small amount of driving current, the phase change memory device is fabricated to have a high driving speed and a high integration.

  • POP-UP TYPE HOLDER AND STAND MOBILE DEVICE ACCESSORY FOR HOLDING EYEGLASSES
    Publication number: 20180348541
    Abstract: A pop-up type holder and stand mobile phone accessory includes a base, a collapsible member, and a foot. The collapsible member is connected to the base at a first end, and to the foot at a second end. The base is configured to be attached or mounted to the back of a mobile device, or to the case of a mobile device, and the foot can be extended be expanding the collapsible member for use, to facilitate holding the mobile device by a user, or retained against the base by collapsing the collapsible member. The base or the foot includes a pocket that is configured to hold and retain a pair of folding nose clip-on type eyeglasses.

  • Easy access pop off relief valve
    Patent number: 5098026
    Abstract: A pulverizer roll wheel assembly comprises a bracket with an opening therein for fixing the outer end of a roller shaft. Bearings mount a roller wheel with pulverizing tire to the inner end of the shaft for rotation of the pulverizer. A lip seal assembly separates an oil space around the inner end of the shaft with an air space around the outer end of the shaft. A pop off relief valve normally positioned near the lip seal is repositioned to the outer face of the shaft for easier access. A cover extends over the relocated valve for extending the air space around the relocated valve.

    Publication number: 20080244939
    Abstract: A hanging basket display collar includes at least one pop-put panel when the conical collar is formed. In one embodiment, the pop-out panel is formed by two facing semicircular die cuts which define a generally circular pop-out panel coupled by integral hinges at the top and bottom edges, such that, when the collar is formed, the disk-shaped pop-out panel remains flat and extends in a plane spaced outwardly from the conical surface of the collar. A plurality of such pop-out panels can he provided and include printed plant identification and care information thereon.

  • Vehicle pop up hood apparatus
    Patent number: 8307935
    Abstract: In a vehicle pop-up hood apparatus in which a rod is extended and a hood is pushed up by the operation of an actuator at a time of collision with a collision body, collision energy is absorbed with high efficiency when a collision load of a predetermined value or greater is input to an area near a hood pushed up position. Actuator (18) operates such that rod (20) moves in an axial direction toward a hood upper side, pushes up a rear edge side of hood rocker (12) and holds it at that position and, in that state, when a collision load of a predetermined value or greater acts from a hood upper side to near the pushed up position of the hood, push portion (54) slides along pushed up surface (38) of hinge arm (30) towards a vehicle rear side, and rod (20) is made to bend in conjunction therewith.

  • SELECTIVE DISTRIBUTION OF ROUTING INFORMATION
    Publication number: 20170230289
    Abstract: A distributed system for collecting and processing packet routing information is provided. A service provider, such as a content delivery network service provider, can maintain multiple Points of Presence (“POPs”). Routing computing devices associated with each POP can forward information about the packet routing information to a packet routing management component. The packet routing component can process the information provided by the various POPs. The packet routing component can then update, or otherwise modify, packet routing information used by one or more of the POPs. Accordingly, the packet routing management component can then selectively distribute the updated or modified packet routing information, including the distribution to all POPs, the targeted distribution to specific POPs and the creation of centrally accessible routing information.

  • Method and system for handling computer network attacks
    Publication number: 20110213882
    Abstract: A method and apparatus for serving content requests using global and local load balancing techniques is provided. Web site content is cached using two or more point of presences (POPs), wherein each POP has at least one DNS server. Each DNS server is associated with the same anycast IP address. A domain name resolution request is transmitted to the POP in closest network proximity for resolution based on the anycast IP address. Once the domain name resolution request is received at a particular POP, local load balancing techniques are performed to dynamically select the appropriate Web server at the POP for use in resolving the domain name resolution request. Approaches are described for handling bursts of traffic at a particular POP, security, and recovering from the failure of various components of the system.
