  • Publication number: 20170277852
    Abstract: A system managing health-related issues (e.g., diabetes) includes a measurement device to measure a health characteristic and a processing device communicatively coupled to the measurement device. The processing device receives the measurement from the measurement device. The processing device includes at least one memory device, a processor, and a user interface. The at least one memory device stores the one or more measurements and computer-readable instructions for a healthcare application. The processor executes the healthcare application. The health care application displays and receives, via the user interface, supplemental health data in association with the one or more measurements. The healthcare application allows a user to input the supplemental data according to adherence burst prompting, measurement and logging prescription, retroactive logging, and/or data display with an electronic calendar.

  • Patent number: 9728616
    Abstract: The present invention provides a high-voltage metal-oxide-semiconductor transistor device and a manufacturing method thereof. First, a semiconductor substrate is provided and a dielectric layer and a conductive layer sequentially stacked on the semiconductor substrate. Then, the conductive layer is patterned to form a gate and a dummy gate disposed at a first side of the gate and followed by forming a first spacer between the gate and the dummy gate and a second spacer at a second side of the gate opposite to the first side, wherein the first spacer includes an indentation. Subsequently, the dummy gate is removed.

  • Publication number: 20170200650
    Abstract: A method for fabricating a semiconductor device structure is shown. A gate dielectric layer is formed on a substrate. A portion of the gate dielectric layer, which is located on a part of the substrate in which an S/D region is to be formed, is removed. A gate electrode is formed on the remaining gate dielectric layer. A spacer is formed on the sidewall of the gate electrode and the sidewall of the gate dielectric layer. The S/D region is then formed in the part of the substrate beside the spacer.

  • Publication number: 20160085331
    Abstract: In one aspect of the teachings herein, a physical activity tracking system includes a wearable electronic device that uses dual touch points for detecting control inputs by a user. Processing within the device complements the dual touch point interface by requiring simultaneous touch detections to register user inputs to the device, and by mapping dual-touch detections of different duration to different control actions. Use of the dual-touch arrangement and the associated processing provides a number of advantages, including intuitive operation and minimization of accidental activations by the user. Other advantages of the touch interface include the ability to seat or mount the device in a variety of carriers, such as bracelets, etc., that complement wearability of the device, while still allowing for convenient charging.
