UCLA researchers in the Department of Electrical and Computer Engineering have developed a novel method for real-time detection and characterization of pulsed THz waveforms that features differential detection of high sensitivity, and phase diversity to overcome the dispersion penalty for wideband operation.

Method and Apparatus for Movement Therapy Gaming System

Rehabilitation therapy, while an important tool for the long term recovery of patients affected by brain injury or disease, is expensive and requires one-on-one attention from a certified healthcare professional. UCI researchers have developed a computer-based system that provides arm movement therapy for patients. The system allows patients to independently practice hand and arm movements, improving therapeutic outcomes, while reducing hospital visits and cost for both patients and healthcare providers.

Array Atomic Force Microscopy Enabling Simultaneous Multi-point and Multi-modal Nanoscale Analyses

Nanoscale multipoint structure-function analysis is essential for deciphering the complexity of multiscale physical and biological systems. Atomic force microscopy (AFM) allows nanoscale structure-function imaging in various operating environments and can be integrated seamlessly with disparate probe-based sensing and manipulation technologies. However, conventional AFMs only permit sequential single-point analysis. Widespread adoption of array AFMs for simultaneous multi-point study is still challenging due to the intrinsic limitations of existing technological approaches.

Near-Zero Power Fully Integrated CMOS Temperature Sensor

With the planned proliferation of the Internet-of-Things, billions of power limited wireless sensing devices are expected to be sold worldwide.  Within that group is a large subset of applications in which temperature sensing will be important.  Needed for this application space are ultra-small and ultra-low-power temperature sensors. 

Low-noise Low-power ADC for Direct Biopotential Recording in Neuroscience Applications

High-density multi-channel neural recording is critical to driving advances in neuroscience and neuroengineering through increasing the spatial resolution and dynamic range of brain-machine interfaces.  Neural signal acquisition ICs have conventionally been designed composed of two distinct functional blocks per recording channel: a low-noise amplifier front-end (AFE), and an analog-digital converter (ADC).  Hybrid architectures utilizing oversampling ADCs with digital feedback have seen recent adoption due to their increased power and area efficiency. However, input dynamic range (DR) is still relatively limited due to aggressive supply voltage scaling and/or capacitive sampling noise.

Cloud- enabled Wireless pH Monitoring in Laboratory Sample Vials

A team of inventors at UCI have developed a miniaturized, wireless pH sensing system capable of monitoring the pH of laboratory samples in real-time with cloud-enabled connections for data collection. The sensor is designed to fit into the caps of standard sample vials, providing continuous measurements and eliminating the need to open vials during sensing.

Energy Radiator Using Strain-Mediated Spin Torque Nano-Oscillator (S-STNO)

UCLA researchers in the Department of Mechanical and Aerospace Engineering have developed an energy radiator based on a spin torque nano-oscillator that does not require the application of an external field.

Source Tracking Though Spectral Matching To Mass Spec Databases

Modern metabolomics, proteomics and natural product datasets have now reached into the millions of tandem mass (MS/MS) spectra. The rapidly growing size of these datasets precludes laborious manual data interpretation of all of the data. While MS/MS spectral library search approaches match spectra in an automated fashion, the limited size of available spectral libraries limits identification rates of datasets to single digit percentages. In addition, the sharing of experimental MS/MS data between researchers is not that common. What is needed is a way to organize both identified and unidentified spectra into structurally related molecular families that is searchable.

Secure Advanced Monitoring Systems

Maintaining secure networks is critical for large and high-value institutions, but providing technical staff with remote direct access to sensitive systems and real-time operational data can be vital to protecting value. For example, UC San Diego maintains highly-secure networks, yet there is a need to provide monitoring for freezer systems that contain priceless samples and materials that are often irreplaceable

Flavonol Profile as a Sun Exposure Assessor for Grapes

Researchers at the University of California, Davis have developed a solar radiation assessment method for grapes that uses a flavonol profile. This method can be done using either HPLC or through the computer processing of the absorption spectra of a purified flavonol extract via a purification kit.

New Method For Underwater Wireless Communication

Underwater communication presents many challenges in order to transmit data with large bandwidth and over long distance and/or over a wide area.  Indeed, water absorption, scattering and turbidity prevent radio waves to be used similarly as in air. Acoustic transmission has therefore been the standard technology for decades, but suffers from a very small bandwidth (less than 1 Mbps), whereas a video stream or conventional large data stream requires a bandwidth higher than 10Mbps.  Free Space Optical systems have been developed and tested underwater lately taking advantage of the development of lasers and LEDS with wavelengths around 500nm. In this range, water absorption is minimal and optical communication range could theoretically reach 150m with a bandwidth in the tens of Mbps. Large distance communication and correct alignment between the transmitter and the receiver remain however challenging.   UC Berkeley researchers have developed a new method for long-distance and/or wide­area underwater wireless communication using Autonomous Underwater Vehicles (AUVs) equipped with a Free Space Optical system allowing high bandwidth communication. The high stability and agility of the AUV allows to maintain a correct alignment between the receiver and the transmitter of two different AUVs keeping the data communication operational.
