Determining situational patterns of use for computing systems

Techniques for determining situational patterns of use of computing systems are disclosed. A situational pattern of use can be determined based on the situations encountered by the computing system as the situations occur without having to predefine a set of situations. Generally, a situation can be determined and/or defined based on the context of use of the computing system when the use occurs. The context of use can, for example, be determined based on internal and external variables including the physical environment where a device is used and biological data associated with a person who uses the device. The state of use of the computing system can, for example, be determined based on the state (or status) of one or more components of the computing system (e.g., the state of one or more active applications that are being used by person). Similar to the context of use, the state of use can be determined as the use occurs without having to predefine potential uses of the computing system (e.g., there is no need to predefine or know the applications that will be used on a device). Moreover, the state of use can be connected to context of use defining a situation in which the state of use has occurred to allow determining a pattern of use of the computing system at least based on the association of the state of use with the situation effectively defined by the contextual usage data which can be obtained as and when the use occurs.

Variable area flow rate meter using optical sensing of float position in the duct

A flowmeter has a variable area, vertically-oriented duct through which flows fluid whose flow rate is to be determined. A float in the duct assumes a position in the duct that depends on the flow rate of fluid in the duct. A window is located at an end of the duct in alignment with a longitudinal axis of the duct. A transducer unit projects a signal beam comprising either light in the ultraviolet, visible, or infrared spectrum, or ultrasound energy. The signal beam propagates in a beam through the window and along the axis toward the float. The transducer includes a sensor that detects the signal energy returned by the float by reflection or some other mechanism to the transducer unit. The intensity or delay time in the returned signal energy indicates the position of the float in the duct, from which the fluid flow rate may be determined.

Electronic fluidic indicator and method of indicating

InactiveUS20130002438A1Reliable and cost effective detectionCost-effective detectionInput/output for user-computer interactionStampsEngineeringElectrical conductor
The invention relates to providing detection of an exposure to a physical or chemical phenomenon and revealing information as a response to the exposure. A microfluidic device (20) comprises a microchannel (22) filled at least partly with at least one substance and a conductor (29) providing an intersection area (23a-23d) with the microchannel (22). As a result of exposure to the physical or chemical phenomenon directed to the microchannel (22) or to the substance in the microchannel (22) the microfluidic device (20) is arranged to control electromagnetic characteristic of the conductor (29) in the intersection area (23a-23d). An indicator device (45) comprises the microfluidic device (20) that is connected to means for indicating (40) to indicate the exposure to the phenomenon by giving a visual, sound, scent and / or electhcomagnetic indication. Further a method for detecting exposure to a physical or chemical phenomenon and indicating the exposure is presented.
