Abstract

A monitoring device provided for monitoring the delivery of fluids through a drip chamber. The device includes an electromagnetic radiation (EMR) source and an EMR detector. The device includes a tubing set mount for receiving a flange or other portion of a tubing set, such that fluid falling through the drip chamber of the tubing set is detected by the detector. The device is operable to determine one or more rolling averages based on intervals of drops or time.

Abstract

A device, method, and system are provided for monitoring the delivery of fluids through a drip chamber. The device includes an electromagnetic radiation (EMR) source and an EMR detector. A device body is employed to position the source and detector about the drip chamber so that the source and detector define an optical path across the drip chamber. A processor device is employed to detect fluid drops from differences between detector signal values separated by a lag time. The flow rate is determined from a drip factor and the detection of multiple drops. In the context of delivering intravenous (IV) fluids, a battery powered handheld monitoring device that includes the source, detector, device body, and processor device may be affixed to a drip chamber included in an infusion set. The device includes a user interface, including buttons, a display, and an audio speaker, for the input and output of information.

Abstract

A new user-friendly game editor allows game players with little or no experience to create new games or game levels. Game element structures can be “drawn” using an “auto completion” feature that automatically functionally connects and/or arranges chosen game elements to provide a visually pleasing environment that is easily navigated by game characters. Such technology can allow an end user game player with little or no technical background to easily develop game levels that are fun to play and do not suffer from any significant defects or other problems that would decrease ease of navigation, functionality or amount of fun. The user may share the authored game with other users via a network so other users can retrieve the game and play it on their own game playing devices. Users can provide feedback concerning the fun and functionality of the game. Good feedback can entitle the game author to recognition including for example bonus points. Bonus points can be redeemed for items listed in an online catalog, which in turn can be used to author ever more interesting game play levels.
