  • Patent number: 11056647
    Abstract: A carbon nanotube (CNT) single ion memory (or memory device) may include a mobile ion conductor with a CNT on one side and an ion drift electrode (IDE) on the other side. The mobile ion conductor may be used as a transport medium to shuttle ions to and from the CNT and the IDE. The IDE may move the ions towards or away from the CNT.

  • Patent number: 10851597
    Abstract: A combination of a casing tube and a closed end unthreaded tubular thread protector that has an inside diameter significantly greater than the outside diameter of the casing tube is described. Further, the thread protector is typically much longer than the threaded portion of the associated casing tube such that a significant amount of axial movement of the protector relative to the casing tube is required to remove it therefrom. The casing protector is most typically comprised of a polymeric material, such as polyethylene or polypropylene, that is soft enough as to not damage or mar the threads on the casing in which it is in contact, but stiff enough in the tubular form of the protector to prevent impact loads from being transferred to the threads there beneath.

  • Patent number: 10615744
    Abstract: An apparatus for carrying, retrieving, and characterizing temperature and current-voltage properties of a solar cell may include a metal core printed circuit board (PCB). The metal core PCB includes current-voltage and temperature measurement electronics operated by a remote device via a communication unit. The solar cell is embedded onto the metal core PCB by way of a thermally- and electrically-conducting adhesive material. The current-voltage and temperature electronics and the solar cell are thermally connected to the PCB, and are electrically isolated from each other, while residing on the same plane.

  • Patent number: 9700179
    Abstract: A kitchen utensil comprises a handheld, low friction, cooking and serving spatula that includes: (a) a generally planar, elongated, blade exhibiting a rear portion connected to a handle, and a front portion extending a distance from the rear portion along a generally central axis between lateral sides of the blade; and (b) movable bearings restrained within in suitably dimensioned openings in the blade. These said bearings exhibit substantially free rotational motion within the blade plane to guide food on and off of the blade.

  • Patent number: 8744162
    Abstract: A method and system for evaluating images, such as x-ray image, to provide feedback that can be used for subsequent image acquisition. The feedback may be used to adjust the positioning of a patient with respect to an image capture device, or a setting of the image capture device. The image capture device may be part of a dental x-ray imaging system that generates an x-ray image of the patent and provides the image to a collector service. The image is evaluated by the collector service for positioning errors and other operator correctable issues that may have had an impact on the image quality. A report that includes feedback regarding the operator correctable issues, as well as suggested corrective action, is generated and provided to the imaging system operator.

  • Publication number: 20070011373
    Abstract: A system and method is disclosed for encoding a set of configuration data for a given expander and at some later point comparing the configuration data to a discovered configuration derived from an attempt to discover the operability of each phy or connection point of the storage system. The configuration identifies the phys or connection points that are operable and the mapping of operable connection points to wide ports communicatively of an expander.

  • Publication number: 20060113330
    Abstract: There is a significant market for liquid detergent bottles in the approximate size of 100 fluid ounces. The advantages of this size and design of current containers include convenient value bulk size and the ability to pick up and grasp with one hand for transport and use. A major disadvantage of current designs is that this size and weight container are at the upper limit of what a small woman or elderly user can comfortably hold. A further disadvantage is that the current use/operating sequence of unscrewing the cap, pouring the bottle into the cap, dispensing the cap and then re-attaching the cap requires the careful use of both hands. A final disadvantage is that undesirable residue from the liquid often adheres to rim and surfaces on and around the container due to drips and spills. The objective of this new and improved design is to provide a container that is both easier to use and cleaner to operate, through an automatic, self-dispensing operation that reseals itself after use.
