Tongue Drive System (TDS) is a new unobtrusive, wireless, and wearable assistive device that allows for real time tracking of the voluntary tongue motion in the oral space for communication, control, and navigation applications. The latest TDS prototype appears as a wireless headphone and has been tested in several human subject trials. Producing a smaller and more stable version of the TDS requires...
This demonstration shows a new type of front end for a Retinal Prosthesis/Vision Augmentation (RP/VA) System, as well as a Visual to Auditory Sensory Substitution Device (SSD). Each system serves to process visual scenes then present them in a simplified form (augmented with auditory signals) to assist visually impaired people. Both systems consist of three components: a sensory block to capture the...
This demonstration features two systems showcasing different applications of the Tongue Drive System (TDS). The Multimodal Tongue Drive System (mTDS) serves as a comprehensive human computer interface (HCI) for individuals with severe physical disabilities, while the tongue-operated robotic rehabilitation system (TDS-HM) facilitates rehabilitation of stroke patients during their recovery.
Generating renewable energy while sequestering CO2 using algae has recently attracted significant research attention, mostly directed towards biological methods such as systems biology, genetic engineering and bio-refining for optimizing algae strains. Other approaches focus on chemical screening to adjust culture conditions or culture media. We report for the first time the physiological changes...
According to Global Asthma Report 2014, asthma may affect as many as 334 million people today and prevalence. While symptoms and severity vary from person to person, asthma can be deadly in some circumstances. Asthma can be controlled by medicine. However, one of the hardest parts of controlling asthma is making sure patients are getting the right does of medicine through their inhaler based on doctor's...
A software package will be demonstrated for designing, organizing, and executing sophisticated real-world sensor interrogation protocols, archiving and annotating collected data, and performing differential analysis of experimental results. Users may describe the steps and components of an electronic experiment in abstract terms and may save and share protocol templates for later specialization and...
Spatiotemporal spike patterns from mechano-receptors enable rapid propagation and processing of tactile stimuli. To explore similar mechanisms in neuromorphic touch, tactile sensors of comparable scale and sampling rates are needed. In this demonstration, we present a 4096 element tactile sensor array that is capable of sampling rates of over 5kHz. We exhibit high speed capture of pressure changes...
Visual saliency is an important aspect of the human visual system, as it allows us to process an overwhelming amount of visual information in real-time. Rather than processing the entire visual field in parallel, we focus our attention on only interesting regions for performing higher levels of processing. There are many approaches to modeling visual saliency given visual information, however, few...
We propose to perform a live demonstration on our recently developed multi-modality CMOS sensor array whose sensor pixel each integrates several biosensors with different sensing modalities. Unlike many single-modality sensors, this multi-modality CMOS sensor array can real-time capture multi-physics responses of living cells and tissues with a high spatiotemporal resolution. This live demonstration...
The first demo provides a detailed overview of the key building blocks required for implementing an investigational closed-loop neurostimulator. Fig 1 illustrates the demo set-up for prototyping and testing closed-loop DBS paradigms, which was designed to simulate the conditions of a neural environment. DBS leads are immersed in a saline tank, into which a DAQ device outputs appropriately scaled voltages...
In this live demonstration, we present a smart homecage system, called the Enercage-HC, with closed-loop wireless power transmission, wireless communication, and automated tracking and behavior recognition capabilities. Wireless power is delivered in near-field at 13.56 MHz in the FCC-approved ISM-band through an array of coils designed to provide the entire homecage with homogeneous magnetic field...
In this live demonstration, a Tactile Imaging Sensor is presented, which is used for quantifying the mechanical properties of breast tumor. A tumor or malignancy feels different from the tissue surrounding it, which motivates the development of this system. Currently, a subjective method of clinical breast examination is performed for early detection of breast cancer. The method only provides qualitative...
Our objective is to provide researchers with an inexpensive and fast photoacoustic imaging (PAI) device for exvivo studies. We implement this using an acoustic lens based focusing idea together with photoacoustic technology, resulting in a prototype imaging system. A complete photoacoustic imaging system simulation modeling is presented. The system resolution is evaluated through simulation and experiment...
This paper presents a Microsoft Kinect®-based image processing system that is capable of automated tracking and behavior recognition in freely moving animals. The depth image provided by the Kinect infrared (IR) camera is used in the image processing algorithm, which works under both bright and dark conditions, compared to conventional red-green-blue (RGB) cameras that need proper lighting or LEDs...
A system-on-a-chip (SoC) for interfacing with a high frequency capacitive micromachined ultrasound transducer (CMUT) imaging array is presented at the post-layout simulation level. The SoC receives high and low voltage supply and clock from external sources and transfers the RF echo signal directly through a single wire. It occupies a 1.26 mm2 chip area in a 0.18-μm high voltage CMOS process and consumes...
This paper proposes a method of retrieving multi-scale objects from optical colonoscopy images based on image-recognition techniques. Optical colonoscopy is the most common approach to diagnosing bowel diseases through direct colon and rectum inspections. Periodic optical-colonoscopy examinations are particularly important for detecting cancers at early stages while still treatable. However, diagnostic...
