We present a pulse latch with a measured Vccmin at the circuit of 0.42 V and pulse width of approximately 3 FO4-inverter delays. A wider operating window and reduced dependence on the input rise-time and PVT variations were obtained using a new pulse generator. A pulse in the new generator starts when its input crosses the switching level of its input gate,(More)
This paper presents an inertial based sensing system for real-time three-dimensional measurement of human spinal motion, in a portable and non-invasive manner. Applications of the proposed system range from diagnosis of spine injury to postural monitoring, on-field as well as in the lab setting. The system is comprised of three inertial measurement sensors,(More)
The six-food elimination diet (SFED), where dairy, wheat, eggs, soy, nuts, and seafood are avoided, is an effective treatment for eosinophilic esophagitis (EoE). Patient-related costs of this approach, however, are unknown. We aimed to assess the cost of and ease of shopping for an SFED compared to an unrestricted diet. A dietitian with expertise in EoE(More)
Hand rehabilitation often consists of repetitive exercises, which may result in reduced patient compliance and decreased results. The Mobile Music Touch (MMT) is proposed as an engaging form of hand rehabilitation. MMT is a lightweight, wireless haptic music instruction system consisting of gloves and a mobile Bluetooth-enabled computing device, such as a(More)
Mobile Music Touch (MMT) helps teach users to play piano melodies while they perform other tasks. MMT is a lightweight, wireless haptic music instruction system consisting of fingerless gloves and a mobile Bluetooth enabled computing device, such as a mobile phone. Passages to be learned are loaded into the mobile phone and are played repeatedly while the(More)
We present PianoTouch, a wearable, wireless haptic piano instruction system, composed of (1) five small vibration motors, one for each finger, fitted inside a glove, (2) Bluetooth module mounted on the glove, and (3) piano music output from a laptop. With this system, users hear the piano music, and feel the vibrations indicating which finger is used to(More)
This paper introduces a new interactive tool for teaching ASL to deaf preschool children. Our design makes use of a familiar form-factor, that of a teddy bear, to create a tangible media solution to presenting video content and providing intuitive means of interaction. Children interact with the system by "showing" the bear RFID flash cards to trigger ASL(More)
Physical therapists could make better treatment decisions if they had accurate patient home exercise data but today this information is only available from patient self-report. A more accurate source of data could be gained from wearable computing designed for physical therapy exercise support. Existing systems have been tested in the lab but we have little(More)
