Embodiments of the present disclosure provide for an apparatus for a float with fishing conditions detection capabilities. In one instance, the float may include a float case, one or more sensors disposed inside the float case, and a processing block coupled with the sensors and disposed inside or outside the float case. The processing block may be configured to detect one or more conditions of fishing. To detect the conditions of fishing, the processing block may be configured to receive and process sensor readings from the sensors, and determine the conditions of fishing, based on a result of the processing of the sensor readings. Other embodiments may be described and/or claimed.

A wind detection device with a flexible enclosure, and opening, and a dispensing tube, filled with powder or liquid and designed to be attached to hunting equipment, headgear, or clothing, wherein pressing on the outside of the device causes a puff of powder or vapor to be dispensed into the air, allowing the user to determine wind direction.

Imaging is performed such that a flow-down path of the liquid from the nozzle arranged above a work to an upper surface of the work is included in an imaging field of view (Step S401). A total value of pixel values of pixels belonging to each pixel column composed of the pixels arranged in a line along a flow-down direction of the liquid in an evaluation region corresponding to the flow-down path out of an imaged image is calculated (Step S402-S403). Based on a change mode of the total value in an orthogonal direction orthogonal to the flow-down direction, presence or absence of the flow-down of the liquid is determined (Step S405-S407).

A flow angle probe is provided having (a) a probe flap for contacting a moving fluid within a fluid conduit; (b) a probe body mechanically coupled to the probe flap; (c) a force sensor disposed within the probe body and operationally coupled to the probe flap; and optionally (d) a probe shaft coupled to the probe body. A deflection of the probe flap caused by contact with the moving fluid produces a corresponding force sensor signal output which is minimized by rotation of the probe flap. The angle between this point of minimum deflection and a reference position is taken to be the flow angle of the moving fluid in the vicinity of the probe flap. The novel flow angle probes disclosed herein may be used in a wide variety of turbomachines and fluid processing systems, and applications, including turbomachine design and operational control, and in flow assurance.

The uniqueness of the present invention is the development of methods for determining the source localization of transient pressure events, such as blast and sound waves originating from explosions, or other pressure sources, with the preferred embodiment using the illustrated example of a multi-sensor wearable device (MSWD), but any multi-sensor wearable device may be used. This device combines pressure transducers, inertial sensors, and navigational sensors to identify the direction of a pressure source. The invention employs diverse techniquespressure time-based, pressure amplitude-based, inertial amplitude-based, and/or machine learningto enhance accuracy. The calculated source location can be used to determine a sensors orientation to the source to estimate a reflected and/or incident pressure. The directional analysis is vital for assessing the impact of pressure waves on surfaces, improving injury assessment, and enhancing safety evaluations as the direction of the blast wave may have different effects on injury outcomes.
