20140064350 | NOISE POWER THRESHOLDING AND BALANCING FOR LONG TERM EVOLUTION (LTE) SYMBOL DETECTION - A noise thresholder of a baseband modem integrated circuit (BMIC) compares measured noise variances on corresponding receiver paths to a pre-established threshold minimum value. The noise thresholder assigns as a noise variance value for a corresponding receiver path either (a) a measured noise variance value for each receiver path having a measured noise variance that is larger than the pre-established threshold minimum, and (b) the pre-established threshold minimum value for each receiver path having a measured noise variance that is less than or equal to the pre-established threshold minimum value. A noise balancer performs noise balancing to provide a same signal to noise ratio (SNR) across all receiver paths, based on the assigned noise variances provided at the noise thresholder. A detection engine utilizes a lowest assigned noise variance value and outputs yielded by the noise balancer to simplify equalization computations while providing a high performance symbol detection capability. | 03-06-2014 |

20090137418 | DNA MICROARRAY HAVING HAIRPIN PROBES TETHERED TO NANOSTRUCTURED METAL SURFACE - A sensor chip and detection device are disclosed. The sensor chip includes a substrate, at least a portion of which is covered by a metal nanoparticle film; a first nucleic acid molecule that is characterized by being able to (i) self-anneal into a hairpin conformation and (ii) hybridize specifically to a target nucleic acid molecule, the first nucleic acid molecule having first and second ends, which first end is tethered to the metal nanoparticle film; and a first fluorophore bound to the second end of the first nucleic molecule. When the first nucleic acid molecule is in the hairpin conformation, the metal nanoparticle film substantially quenches fluorescent emissions by the first fluorophore, and when the first nucleic acid molecule is in a non-hairpin conformation fluorescent emissions by the first fluorophore are surface plasmon-enhanced. | 05-28-2009 |
