Abstract: Various embodiments discussed herein enable intelligent resource leak detection and associated user interface.

In some aspects, if a kernel sends a tracing event e. This is because the application should have requested the reference indicator to be removed in memory before the tracing event, as opposed to the kernel acting alone without an application request to remove the reference indicator. If a reference indicator has not been requested to be removed by the time this tracing event occurs, then it is indicative of the application never having sent a request to remove the reference indicator, which is indicative of a resource leak.

Filed: January 10, Data set state visualization comparison lock. Abstract: A user interface that allows the user to lock in a comparison state of an inspector control that provides a view on state of a data set being subjected to transformations.

The inspector control visualizes a state of at least a portion of the data set such as a column, table or database as that data set is navigated by a navigation control. At least under some circumstances, the inspector control also visualizes a comparison state of the data set. A comparison lock control allows the comparison state of the data set to be locked at a particular comparison state regardless of the navigation control navigating the data set.

Accordingly, until the comparison state is unlocked via a comparison unlock control, the inspector control visualizes a current state of the data set along with a visualization of the locked comparison state of the data set. Filed: May 31, Inventor: Chairy Chiu Ying Cheung.

This process takes time and patience. This board of incredible female executives across disciplines at Microsoft assists the inventors to continue to innovate and bring their ideas to life.

Meet the amazing female inventors working to change the world one invention and patent at a time. This Ohio high school team invented an intelligent netting system to decrease man-made debris that enter waterways from residential storm drains, posing a threat to animals who reside in nearby creeks and rivers.

They successfully tested their app in Mexico and continue to test in other countries. This high school team developed an underwater camera to study the prevalence of invasive species in the Great Lakes. The camera is able to take key measurements like salinity and pH level, and they are developing a fish recognition system.

This high school team developed a smart wallet that helps people who are blind or low vision sort their money into their wallet. With only hours to spare at a hackathon, these female MIT engineering students developed a text-to-Braille device. When scanned over text, pins on top of the device translate the text into Braille. Consequently, the output varies in a manner similar to the blood pressure variation. It should be understood that the output of the phase detector will not necessarily be linearly proportional to the blood pressure.

However, variations in blood pressure will be readily apparent, and the magnitude may be determined by suitable calibration of the indicator. It is advantageous to supply the output of the phase detector to a continuous recorder so that a complete record of the subjects blood pressure may be obtained. The recorder output may be calibrated in units of pressure as indicated in FIG. Calibration may be accomplished in any convenient manner.

For example, the subjects blood pressure may be determined by conventional techniques at the same time it is obtained by the apparatus of the invention, and the indicator calibrated accordingly. It will be noted that by making the impressed frequency high compared to the heart beat frequency, the manner in which the blood pressure varies during a single heart beat cycle may be determined.

The frequency components in the blood pressure variation will also be considerably lower than the impressed frequency, and may readily be eliminated in the amplifier so as not to interfere with the measurement. It may often be desired to measure a subjects blood pressure in an environment where ambient pressure variations are present.

There may also be amplitude variations in the outputs of the receiver transducers due to many factors. For example, even though the output of oscillator 13 is maintained constant, the pressure variation impressed on the arterial blood stream by transducer iii may vary due to variations in the attenuation from the skin to the artery. There may also be a varying attenuation along the arterial blood stream, and between the artery and transducers l4 and It is accordingly highly desirable that the indicated blood pressure be made independent of environmental conditions and insensitive to amplitude variations.

In such cases the embodiment shown in FIG. Inasmuch as a substantially fixed applied sinusoidal freqeuency is employed for measuring purposes, it is possible to amplify and sharply filter the outputs of the receiving transducers so as to prevent response to other than the desired frequency, thereby eliminating the efiects of environmental pressure changes at other frequencies.

Accordingly, the outputs of transducers 14 and 15 are supplied to respective amplifiers and filters 31, ' The filters are tuned to the frequency of oscillator 13 FIG. The outputs of amplifier-filters 31, 31 are then supplied to respective limiters 32, 32' so as to substantially eliminate amplitude variations. With sufficient amplification and limiting, the outputs of limiters 32, 32 may be substantially square waves, whose relative phase is the same as that of the input sinusoidal waves.

These square waves are then supplied to a phase detector 33 and thence to indicator Suitable circuits for measuring the phase between square waves are well known in the art. In the event that a phase detector is employed which is inherently insensitive to amplitude variations, limiters 32, 32 may be omitted. As illustrated in the drawings, it is preferred to em ploy a pair of receiving transducers spaced from the transmitting transducer, and utilize Variations in the phase angle between the receiver transducer outputs in order to obtain an indication of blood pressure.

However, it is possible within the broad scope of the invention to employ only a single receiving transducer and measure variations in the time of travel of the continuous-wave pressure variations between transmitting and receiver transducers. Here also, it is preferred to measure changes in phase between the impressed pressure variation and the received pressure variation.

The invention has been described in connection with preferred embodiments thereof. It will be understood, however, that variations and modifications of the arrangements described may be made within the spirit and scope of the invention.
