bat cane“BAT CANE” FOR THE BLIND: Travel canes are often a method of choice for the blind. While there are advanced options such as ultrasonic sensors in some “smart canes,” these are often costly (upwards of 600 dollars). The objective of the Bat Cane team will be to utilize ultrasonic sensors, an Inertial Measurement Unit (IMU), and haptic feedback to provide straight-path deviation alerts and inform the user of upcoming obstacles. These will be implemented in a cost-effective manner that will provide reliable, useful information to the blind. (Bat Cane Poster)

PREDICTING SAFE LIFTING POSTURES: The project is to design a human-machine system that calculates where a person is holding a weight during a lift. A display is shown to the user informing them of a safe operating zone for the load and gives feedback if the user is lifting unsafely.  Two force plates are used to determine the weight and the distance of the weight from the body. The data from the force plates is read into a computer program which provides real time feedback to the user. (Predicting Safe Lifting Postures Poster)

SMART OXoxygenYGEN DELIVERY SYSTEM: In the current hospital setting, supplemental oxygen is delivered to patients at risk for depressed breathing at a constant flow rate. This constant flowing oxygen dilutes the patient’s expired gas, which is used to monitor the patient, and thus monitors may not be able to notify the nurse or doctor that the patient is no longer breathing.  An episode of depressed breathing may cause brain damage or even result in death. These injuries and deaths can be prevented if depressed breathing is detected
early and the patient is prompted to breathe; unfortunately, due to the previously mentioned deficiencies in the existing system, healthcare professionals’ abilities to monitor patients are not sensitive enough.

The smart oxygen delivery system intermittently delivers oxygen as well as provides a constant stream of pressure profile data from within the cannula, which improves patient monitoring.  The system delivers oxygen to the patient in accordance with their natural breathing pattern rather than the constant flow method current devices use. As the patient inhales, the system detects a negative air pressure in the cannula and delivers oxygen to the patient. When the patient exhales the system detects positive pressure and shuts off the oxygen delivery. The smart oxygen delivery device may also improve patient monitoring by allowing sensors to sample non-diluted expired gas. This method may also increase oxygen savings since gas flow is shut off during patient expiration. The system will also be able to detect if the nasal cannula is inadvertently removed from the patient’s nostrils. We believe by delivering oxygen only when the patient inhales that the patient will have a more natural breathing experience, the oxygen levels of the patient will be better monitored, patient injury and death related to oxygen saturation will be reduced, there will be a savings in supplied oxygen, and fire hazards related to supplied oxygen will be reduced.

BowlingTEN-PIN BOWLING ASSISTIVE DEVICE FOR VISUALLY IMPAIRED: Blind bowling assistive device is the next step towards a more independent bowling experience for visually impaired. The objective of the project is to provide a tactile feedback of number of pins left after each try and also the pin which gets hit first by the ball.

The system will use real time images of ten-pin array which will be processed and the information obtained will be sent forward to actuate solenoids of the assistive device to be sensed by the bowler. The ultimate purpose of the device is to enhance the experience of bowling for visually impaired.
