Abstract: A III-nitride power semiconductor based heterojunction device comprising a substrate, a first terminal, a second terminal, a control terminal configured to receive an input switching signal during an active mode of operation and to not receive the input switching signal during a stand-by mode of operation, and an active heterojunction transistor formed on the substrate.

Abstract: A method of implementing administrative services for managing status updates is disclosed. A status update configuration window is provided on a graphical user interface. The status update configuration window comprises a plurality of update settings for configuring recurring status updates. A selection of update settings is received in the status update configuration window comprising an update frequency, a set of update questions, and a schedule for update reminders. The selected update settings are stored as an update template. An update summary window is displayed concurrently with the status update configuration window. The update summary window comprises a limited list of one or more selectable update management functions. A selection of an update management function is received from the update summary window.

Abstract: A method of implementing administrative services for managing group feedback is disclosed. A selection of a feedback visibility setting for a feedback message from a plurality of predefined feedback visibility settings is received via a give feedback tab of a user interface. The feedback message and a selection of one or more recipients are received via the give feedback tab. The feedback message is sent to the selected one or more recipients based on the selected feedback visibility setting. A request for feedback and a selection of one or more feedback providers are received via a request feedback tab of the user interface. The request for feedback is sent to the selected one or more feedback providers. Received feedback responses linked to a user profile of the feedback requestor are stored.

Abstract: Certain embodiments of the present invention provide a system and method for reviewing medical images using a tactile interface to display a bas-relief image. A tactile interface may provide a bas-relief representation of medical imaging data to an end-user. The tactile interface may include an array of tactile elements positioned as a grouping of cylinders arranged in a closely packed array. The cylinders may be raised or lowered independently to create a bas-relief pattern of an object within a medical image. A radiologist may utilize the bas-relief image to physically identify surfaces and edges for the images being viewed. The additional information may allow a radiologist to develop quicker and more accurate diagnoses.
