Targeted Drug

The prevalence of gastrointestinal (GI) diseases such as Crohn’s disease, which is chronic and incurable, are increasing worldwide. Treatment often involves potent drugs with unwanted side effects. The technological–pharmacological combination of capsule endoscopy with ultrasound-mediated targeted drug delivery (UmTDD) described in this paper carries new potential for treatment of these diseases throughout the GI tract. We describe a proof-of-concept UmTDD capsule and present preliminary results to demonstrate its promise as an autonomous tool to treat GI diseases.

Wireless Capsule

Wireless capsule endoscopy (WCE) has been widely used in gastrointestinal (GI) diagnosis that allows the physicians to examine the interior wall of the human GI tract through a pain-free procedure. However, there are still several limitations of the technology, which limits its functionality, ultimately limiting its wide acceptance. Its counterpart, the wired endoscopic system is a painful procedure that demotivates patients from going through the procedure, and adversely affects early diagnosis. Furthermore, the current generation of capsules is unable to automate the detection of abnormality. As a result, physicians are required to spend longer hours to examine each image from the endoscopic capsule for abnormalities, which makes this technology tiresome and error-prone. Early detection of cancer is important to improve the survival rate in patients with colorectal cancer. Hence, a fluorescence-imaging-based endoscopic capsule that automates the detection process of colorectal cancer was designed and developed in our lab. The proof of concept of this endoscopic capsule was tested on porcine intestine and liquid phantom. The proposed WCE system offers great possibilities for future applicability in selective and specific detection of other fluorescently labelled cancers.

This paper describes a simple low-cost approach to adding an element of haptic interaction within a virtual environment. Using off-the-shelf hardware and software we describe a simple setup that can be used to explore physically virtual objects in space. This setup comprises of a prototype glove with a number of vibrating actuators to provide the haptic feedback, a Kinect camera for the tracking of the user's hand and a virtual reality development environment. As proof of concept and to test the efficiency of the system as well as its potential applications, we developed a simple application where we created 4 different shapes within a virtual environment in order to try to explore them and guess their shape through touch alone.

The 2018 NASA Academy at Langley Research Center created proof-of-concept mixed reality (MR) and traditional simulators to enable quick vehicle concept prototyping and data collection for human factors studies. Urban Air Mobility (UAM) vehicle concepts were implemented as the focus for these simulators due to recent and dramatic rise in subject interest. The team used X-Plane 11 to model flight dynamics, and Unity for the virtual reality (VR) aspect of the MR simulator and to model the control panel in the traditional simulator. A physical version of the virtual control panel was also fabricated to provide haptic feedback to maintain the immersion for the MR simulator.
