Patent number: 11357729Abstract: A method for administering solid water particles to prevent bacteria growth in living organisms utilizes a solid water particle (SWP) solution to attract and kill a bacterium through polarization. The method inhibits growth of a bacterium or an enveloped virus with an inorganic solution comprised substantially of SWP. The SWP kill the bacterium by providing a solution comprised substantially of SWP having inherent dipole characteristics that generate an electric field. The generated electric field attracts a bacterium to the SWP. Once engaged, the bacterium cannot move. The electric field also creates sufficient internal pressure in the bacterium, which bursts the cell walls of the bacterium, thereby killing bacterium. This mechanism also kills superbug, which are drug resistant bacteria. The method is also efficacious for killing enveloped viruses in the same manner. Further, administering the SWP solution into the mouth for a duration, helps reduce tooth pain and treat periodontal diseases.Type: GrantFiled: April 8, 2020Date of Patent: June 14, 2022Inventor: Shui Yin Lo

Patent number: 9059778Abstract: A method and apparatus provide signal compression for transfer over serial data links in a base transceiver system (BTS) of a wireless communication network. For the uplink, an RF unit of the BTS applies frequency domain compression of baseband signal samples, resulting from analog to digital conversion of received analog signals followed by digital downconversion, forming compressed coefficients. After transfer over the serial data link, the baseband processor then applies frequency domain decompression to the compressed coefficients prior to normal signal processing. For the downlink, the baseband processor applies frequency domain compression of baseband signal samples and transfers the compressed coefficients to the RF unit. The RF unit applies frequency domain decompression to the compressed coefficients prior to digital upconversion and digital to analog conversion, generating the analog signal for transmission over the antenna.Type: GrantFiled: January 4, 2012Date of Patent: June 16, 2015Assignee: Integrated Device Technology Inc.Inventor: Yi Ling

Patent number: 8575155Abstract: A composition and method is provided for modifying sperm fertility in mammals for the purpose of biasing the gender in favor of male offspring. The composition includes an amount of a class of compounds of phenoxazine or phenothiazine, having the structure (FIG. 1) and ionic derivatives thereof, wherein R1 is H, a lower alkyl group or N(R3)2, R2 is N, S, O, and R3 is H or a lower alkyl group. A second component of the composition is an amount of a hexose sugar or the phosphorylated hexose esters of such. When mixed with living sperm prior to or at the time of insemination, the composition results in modified rates of conception and an alteration of the birth sex ratio.Type: GrantFiled: November 26, 2008Date of Patent: November 5, 2013Inventor: Timothy James Williams
