Free-space optical (FSO) communications
Abstract
USC researchers present a system to minimize turbulence interference in FSO communications. The method utilizes a frequency-offset Gaussian pilot tone transmitted along with the data signal, so that both undergo comparable turbulence and modal power coupling. Using a photodetector that optoelectronically...

Abstract
USC researchers have developed LightSecAgg, a novel approach for secure aggregation that guarantees privacy and dropout-resiliency while significantly cutting the overhead for resiliency against dropped users. Utilizing a “one-shot aggregate-mask reconstruction of the active users...

Market Opportunity
Modern radiofrequency (RF) communication systems have high spectral efficiency modulations, which lead to large peak to average power ratios (PAPRs). To prevent excessive amplification of these peaks and other nonlinearities, power amplifiers (PAs) need to “back off” from operating at maximum linear power, and instead...

Market Opportunity
Infrared photodetectors are used in a wide variety of applications. Depending on the intensity of light signals and the type of information to be obtained, photo sensitivity and S/N required of infrared detectors differ. To improve the S/N, cooling the infrared detector will be necessary.

Market Opportunity
Light-Field imaging captures information about the incident angle of light rays in space, making it possible to adjust focus after an image has been captured. Adding lenses or apertures to CMOS sensors are two common ways to detect incident angle. However, the size of the sensor is relatively large, due to lenses or apertures used...

Market Opportunity
Sensing and communication using the millimeter wave band is a promising new approach for applications like mm-wave 5G systems and radar. These systems generally utilize power amplifiers (PAs), the peak and power back-off efficiency of which is crucial for power and thermal management. While class E/F switching PA has emerged as a...

Market Opportunity
Vat photopolymerization offers benefits over soft lithography for microfluidic device production, but the technique struggles with controlled micrometer- sized channels due to transparent resin's deep light penetration. This results in over-curing and channel blockages. There is a potential market opportunity for the development...

Treatment for organ rejection and autoimmune diseases
Drug carrier
Abstract
USC researchers have developed a novel strategy to carry CsA by binding it to its cognate receptor, cyclophilin. Significantly improved pharmacokinetic (PK) profile and therefore reduced systemic side effect were achieved by fusing cyclophilin with different types of elastin-like...

Prognostic biomarkers for brain tumors and immunotherapies for glioblastoma multiforme
RNA based biotherapeutics
Abstract
USC researchers have discovered long non-coding RNAs (lncRNAs) that were aberrantly expressed specifically in GBM brains relative to normal brains. These lncRNAs had prognostic significance and could serve as prognostic...

3D fabrication
Abstract
USC researchers have developed reusable and automatic supports for use in 3D printers. This invention allows for fewer printed supports during the manufacturing process, thereby reducing print time for techniques including fused deposition modeling and stereolithography. The supports come a standardized size, similar to...
