Nathan N. Ng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8905795
    Abstract: Spring-loaded contacts having an improved reliability. One example may provide spring-loaded contacts having a reduced likelihood of entanglement between a spring and a plunger. For example, a piston may be placed between a plunger and a spring. The piston may have a head portion that is wider than the diameter of the spring and located between the spring and the plunger to isolate the spring and the plunger. In these and other examples, an additional object, such as a sphere, may be placed between the plunger and spring. In another example, two additional objects, such as two spheres, may be placed between a plunger and piston.

  • Patent number: 8753132
    Abstract: Power plugs that provide reliable functionality, may be reliably manufactured, and have a pleasant appearance. One example may provide a power plug that functions in a reliable manner by providing a ground connection that may maintain its shape over several insertions and removals from a wall socket. A relatively large ground block may act as a heat sink to help reduce plug temperature during operation. Another example may provide a power plug that may be reliably manufactured by forming the ground block as a solid piece to prevent buckling and bending during plug manufacturing that may otherwise result. Another example may provide a power plug that has an attractive appearance by employing a bridge having a flat surface such that after an overmold is formed over the bridge, a face of the plug has a resulting flat, smooth appearance.

  • Publication number: 20140124236
    Abstract: Cables capable of high-speed data transmission and having a low insertion loss. Examples may mitigate the effect of the suckout component of insertion loss by providing cables that eliminated, shift, or reduce the suckout. Examples may eliminate, or at least partially eliminate, the suckout component by providing a continuous return path. Others may shift the frequency of the suckout component to a high frequency where it no longer interferes or significantly attenuates signals being conveyed by the cable. Still others may reduce or control the magnitude of the suckout component.

  • Publication number: 20130327559
    Abstract: Power cables having improved strength, a uniform feel, good flexibility, and consistent series resistance. One example may use one or more aramid fibers to strengthen a power cable. These fibers may be flattened such that they have a low profile in the direction of a diameter of the cable. A thickness and number of wires in one or more conductors in the cables may be adjusted to provide a good feel and good flexibility. The wires may also be twisted during the construction to improve flexibility. Another example may control variations in series resistance varying a number of wires in the one or more conductors.
