Abstract: The 4T2R cell comprises a write transistor, a first variable resistive element, a first transistor, a second variable resistive element, a second transistor, and a charge control transistor. The first transistor is electrically coupled to the first variable resistive element in series, and the second transistor is electrically coupled to the second variable resistive element in series, for providing search paths. For operating in a search phase, a pulse voltage is applied across the gate electrode and the source electrode of the first transistor (or across the gate electrode and the source electrode of the second transistor) for determining whether the gate voltage of the charge control transistor changes larger than a match threshold during the period of the pulse. Different RC-delay of the variable resistive elements controlling the voltage change speed of the gate voltage of the charge control transistor determines the matching result.

Abstract: A peritoneal dialysis machine including a membrane pump and a touch screen display that includes a mode-indicating portion and an operation-descriptive portion, the mode-indicating portion having a plurality of touch sensitive indicia each indicating one of a plurality of modes in which the machine can operate, the display being used to keep a patient continually informed of which one mode of at least three operating modes the machine is operating in, as the operation-descriptive portion changes to display details of a specific operation being carried out within the one mode, the indicia for each of the three operating modes always being visible to the patient while the machine is operating, the operating mode being selected by the patient touching one of the indicia on the screen.

Abstract: A peritoneal dialysis system includes: an enclosure including an actuation surface and a door; a stepper motor housed by the enclosure; a pump head and a solid pump piston structurally linking the pump head to the stepper motor; and a disposable unit accepted by the enclosure, the disposable unit including a flexible membrane attached to a rigid piece, the actuation surface of the enclosure and the disposable unit so configured and arranged that when the stepper motor turns and consequently translates the solid pump piston and the pump head towards the door, the pump head physically contacts and stretches the membrane from a relaxed position to a stretched position, and when the stepper motor turns and consequently translates the solid pump piston and the pump head away from the door, the membrane follows the pump head and transitions from the stretched position to the relaxed position.

Abstract: Systems and methods for associating a geographic location with an Internet protocol (IP address) are disclosed. Generally, an IP address to location module determines whether a geographic location is associated with a common IP address in a majority of IP address to location data sets. The IP address to location module then stores an association between a geographic location and the IP address in a master IP address to location data set based on whether a geographic location is associated with a common IP address in a majority of IP address to location data sets.

Abstract: The present application is directed to systems and methods for associating a geographic location with an IP address. Generally, a plurality of localized search queries of search queries received at an Internet search engine are determined, where each of the plurality of localized search queries is associated with a location. A geo tag is associated with each of the plurality of localized search queries and a subset of the plurality of localized search queries that are associated with a first IP address is identified. The subset of the plurality of localized search queries is clustered into a spatial cluster including localized search queries associated with geo tags located within a defined distance of a geo tag associated with at least one other localized search query of the cluster. A geographic location associated with a geographic center of the cluster is then associated with the first IP address.

Abstract: A wheel rim cover includes a cover body, a plurality of fitting blocks and a ring. Each fitting block has a press member to fit with a recessed edge of each fixing base of the cover body, with a stop member of each fitting block stopping at a projection of each fixing base, and with a hook member of each fitting block hooking in a hook hole of each fixing base. Then ring fits in all insert grooves of all the fitting blocks, forcing the hook members tightly hook with the hook holes of the fixing bases. The fitting blocks are convenient to assemble with and disassemble from the fixing bases so that cover bodies piled up take small space to reduce the cost for packaging and transporting.

Abstract: A wheel cover in the invention has a wheel cover body including fixing bases fixed thereon and each having at least one first hook hole; securing members connected to the fixing bases and each having at least one second hook hole; springs each having both ends for respectively hooking into each of the first hook holes and each of the corresponding second hook holes, whereby the securing members can be connected to the fixing bases and moved to and fro under the resilience of the springs so that in case that a tire of an automobile is forcedly deformed to jostle against the wheel cover while the automobile is driven on a rough road or runs over hard objects, the wheel cover body can follow the resilient to-and-fro movements of the securing members to prevent the wheel cover from coming off or being burst out of a wheel rim.
