Issue Date: 2019-09-10Matyjas; John (New York Mills, NY), Su; Weifeng (East Amherst, NY)
BACKGROUND Multiple-input-multiple-output (MIMO) communication techniques are widely deployed in ground or near-ground wireless cellular and local area networks such as 4G LTE and Wi-fi networks. They provide substantial capacity increases compared to conventional single-input-single-output (SISO) systems. In cellular or Wi-fi environments, wireless channels between transmit antennas and receive antennas exhibit random fading due to rich scattering, which is often characterized as Rayleigh... Read More

Method and apparatus for waveform independent congestion control
Issue Date: 2019-08-20Pudlewski; Scott (Whitesboro, NY)
BACKGROUND The transmission control protocol (TCP) provides a mechanism for node-to-node connectivity in a packet-based network, such as the Internet. Congestion in a network occurs when a node is carrying more data than it can handle. TCP provides a number of congestion control protocols, from TCP Tahoe to the more modern CUBIC and Compound TCP, and finally to optimal computer-generated TCP implementations. All of the protocols, with the exception of optimal computer-generated TCP, use... Read More

Apollonian-loaded split-ring resonator and method for designing the same
Issue Date: 2019-05-28Sikora; Paul A. (Holland Patent, NY), Southcott; Mark A. (Rome, NY)
BACKGROUND OF THE INVENTION The Split Ring Resonator (SRR) is one of the most common unit cell configurations found in metamaterials. One of the main problems being faced with traditional SRR geometries is a lack of bandwidth. Additionally, an area of great interest would be attaining in some level of reconfigurability with a metamaterial surface. Referring to FIG. 1a and its circuit equivalent in FIG. 1b, the traditional SRR configuration is a planar ring 10 with some number of gaps 20 in... Read More

Glitch free asynchronous clock multiplexer
Issue Date: 2019-02-12Lapiana; Giuseppe A. (Liverpool, NY)
BACKGROUND OF THE INVENTION The Joint Test Action Group (JTAG) developed a 5 pin test access port standard which is commonly referred to as JTAG. JTAG is used for a variety of Integrated Circuit (IC) and board level tests. During IC test and debug it can be helpful to allow the JTAG (TCK) clock to be driven onto the main clock tree. This allows input test vectors to be loaded while the clock is stable and then allows the IC to function under normal operating conditions. Referring to FIG. 3,... Read More
