Abstract: A device for measuring a rate of production of urine in a patient comprising a catheter; a pressure transducer; and a means for measuring the amount of urine produced. Urine flow from the bladder is prevented until a predetermined pressure is reached in the bladder. Urine flow is then allowed; the bladder pressure and the volume of urine exiting the bladder are measured. When the bladder pressure reaches a second, lower predetermined pressure, urine flow is again prevented. From the measured pressure during urine flow and from the volume of urine exiting the bladder, the intra-abdominal pressure and the urine production rate can be determined.

Abstract: A dual active valve positive displacement pump comprising: A housing holding the pump's components. A piston with an internal cavity divided into two fluidly-isolated volumes by a freely-moving diaphragm, one of the two volumes being fluidly connected with a volume between piston and housing which contains driver pressure from a pressure source. The piston is reciprocally movable inside the housing under positive or negative driver pressure. An active inlet valve operable by driver pressure actuates when the driver pressure is more than the maximum pressure at the pump inlet port. An active outlet valve operable by driver pressure actuates when the driver pressure is less than the minimum pressure at the pump outlet port. The diaphragm separates pumped fluid from operational fluid used to move the diaphragm inside the piston cavity and transmits pressure at the inlet port when the inlet valve is open, and at the outlet port when the outlet valve is open.

Abstract: A system for determining an lop of a subject includes a pressurizing device for applying pressure of varying magnitude over an external surface of an eye of the subject; a monitoring device for monitoring internal vasculature of the eye and vasculature on or around the eye; and a processing unit for correlating a first pressure or pressure range with pulsation or collapse of the internal vasculature of the eye and a second pressure or pressure range with pulsation or collapse of the vasculature on or around the eye to thereby derive the IOP of the subject.

Abstract: A fluid pump for pumping a fluid between a fluid inlet and a fluid outlet has a chamber with an inlet and an outlet. At least one flow restricting element is disposed at a flow line portion and is configured to resonate along a continuum of states between a first end state and a second end state to thereby affect fluid flow profile through said inlet or said outlet. While resonating the element transitions through a range of states differing in the flow they permit. A driver is configured to modulate conditions in the chamber or on the at least one flow restricting element at a characteristic frequency profile, thereby inducing the at least one flow restricting element to resonate between the first and second states at about said characteristic frequency profile.

Abstract: Technologies are generally described for adjustment of displayed content based on recognition of viewer. In some examples, content that may include data, as well as, control elements associated with functionality of a surveillance system. The content may be displayed to a viewer based on the viewer's credentials. Responsive to detection of another viewer, the displayed content may be modified based on credentials of the other viewer. Viewers may be detected through a variety of techniques and displayed content may be associated with different authority levels. In other examples, content may be blocked from display if a viewer in a restricted list is detected in view of a display device.

Abstract: Technologies are generally described for prevention of duplicate monitored areas in a surveillance environment. In some examples, a field of view (FOV) of a security personnel may be estimated. An image capture device with a coverage area that potentially includes the FOV of the security personnel may be identified and its FOV estimated as well. Next, an overlap amount between the estimated FOVs of the image capture device and security personnel may be determined. When the overlap amount exceeds a threshold, content provided by the image capture device may be assigned a low priority. The low priority content may be blocked from display, selected with lower priority among multiple available contents, or displayed with an indication of the low priority on a control center display. The FOV of the security personnel may be an actual view of a person or the FOV of a camera associated with the security personnel.

Abstract: Technologies are generally described for methods and systems effective to generate an alert through sentiment analysis. In some examples, a device may receive initial image data, where the initial image data may be associated with an initial image. The device may further detect sentiment values in the initial image data, where the sentiment values may correspond to two or more locations in the initial image. The device may further compare respective sentiment values with an sentiment threshold in order to identify region data in the initial image data that satisfies the sentiment threshold. The device may further generate the alert based on the identification of the first region data.

Abstract: Technologies are generally described for detection of foot edema through in-shoe pressure sensors and analysis of detected pressure values. Multiple pressure sensors may be employed in contact with a foot. The pressure sensors may detect pressure generated on a surface of the foot by fluid accumulation within cells of the foot. A change in pressure may be monitored by analyzing pressure values received from the pressure sensors. In some embodiments, a pressure rebound curve may be determined while monitoring the change in the pressure. A comparison between a newly acquired pressure rebound curve and an established-normal pressure rebound curve corresponding to a healthy foot may be made. If the pressure rebound curve is determined to indicate a slower change (rebound) in detected pressure than a change in pressure indicated by the normal pressure rebound curve, the presence of foot edema may be inferred.
