Configurable flow velocimeter
A monitoring device includes a sensor module disposed between an aeroshell and a cavity assembly. A surface of the aeroshell and a surface of the cavity assembly may form a flow-facing surface of the monitoring device. A junction area on the flow-facing surface within which the aeroshell abuts the cavity assembly may be a smooth surface to minimize the disruption to the surrounding flow of fluid. The sensor module may sample the absolute pressure from ports distributed about the flow-facing surface. The absolute pressure measurements may be used to compute the velocity of the fluid flow, including speed and/or direction. The monitoring device may be powered by inductively received energy or harvested energy. In one variant of the monitoring device, the monitoring device may be constructed from an electrically coupled mosaic of flexible thin-profile tiles, each of which may be responsible for one functional aspect of the monitoring device.

Indoor intrusion detection
A computer-implemented method, a system, and a computer program product for detecting objects are disclosed. The method can include receiving, by a computer communicatively connected to a plurality of anemometers positioned throughout the space, first sensor data from the plurality of anemometers, creating a baseline profile of airflow in the space based on the first sensor data, and receiving second sensor data from the plurality of anemometers at a different time than the first sensor data. The method can include comparing the second sensor data with the first sensor data to determine first different data, rendering, in response to determining that the second sensor data is different from the first sensor data, a representation of the object using the first different data and first location data related to the first different data, and calculating a vector associated with the object using the first different data and the first location data.

Device, system and method for monitoring river flow velocity based on differential pressure measurement
The present invention relates to a device, a system and a method for monitoring river flow velocity based on differential pressure measurement, comprising: a hull floating on a water surface with an aspect ratio of the hull being greater than one, characterized in that pressure sensors are respectively provided on an upstream face of a front end and a downstream face of a rear end below the floatation line of a ship; an electronic instrument is provided in the hull, and the electronic instrument comprises an acquisition module connected to the two pressure sensors, the acquisition module being connected to a data processing module with a memory, and the data processing module being connected to a satellite positioning module and a wireless communication module. According to the present invention, the flow velocity of water flow is measured based on the difference between the the simulated measured upstream face pressure at the bow and the simulated measured downstream face pressure at the stern by an unpowered measuring ship drifting on the water surface. The measured data is transmitted to the data processing center on the ground via the wireless communication network. The present invention enables the flow data to be measured in presence of poor satellite positioning signals and public network signals or no signals, achieving data transmission independent of satellite positioning and public communication networks.

Measurement device with suspended sensors
To simplify architecture of a measurement device for affixing to a wall of a moving object or stationary object located in a flow, a device includes a support having compartments with an opening that opens to the exterior of the support at the free face in which sensors are housed, the support having a free face and a face to come into contact with the wall, the free face being opposite the face. The device includes a cavity with a printed circuit board, the compartments including an opening that opens to the exterior of the support in the cavity. The cavity is made in the free face opening into it. The circuit board is upside down in the cavity with the printed face towards the interior of the support. The sensors attached to the circuit board are suspended in the compartments. The unprinted face affords an aerodynamic smooth and planar surface.
