摘要： An electromagnetic (EM) sensor includes a front end module generating an EM signal using electromagnetic waves transmitted from an external source, a sensor memory storing a portion of a plurality of machine learning models used to recognize the EM signal, and a microcontroller unit for recognizing the external electronic device emitting the electromagnetic waves by inputting feature values extracted from the EM signal to the machine learning models. If the machine learning models stored in the sensor memory are not able to recognize the external device, the feature values may be transmitted to a main processor, and the main processor may compare the feature values to another set of machine learning models.

摘要： System and method for analyzing and evaluating the performance of a directional driller (“DD”) include acquiring and analyzing drilling data in real time, identifying activities and decisions that are the responsibility of the directional driller, and confirming whether or not the directional driller's decisions were appropriate or not and in what timeframe. The system and method may provide output information for evaluation purposes, for example, in the form of a directional drilling quality report. The directional drilling quality report may allow evaluation of an individual directional driller and also comparison of directional drillers relative to each other. The use of real-time drilling data allows the report to be modified to reflect actual drilling conditions and objectives as needed.

摘要： A helmet safety system comprises a first set of sensors coupled to a helmet, a second set of sensors coupled to a vehicle, and one or more microcontrollers coupled to the first and second sets of sensors. The one or more microcontrollers can receive sensor data from the first and second sets of sensors and determine, based on the sensor data, that a user is using the bicycle but not wearing the helmet. Responsive to determining that the user is using the bicycle without wearing the helmet, the one or more microcontrollers perform remedial actions, such as disabling or limiting a functionality of the bicycle, emitting an alarm or alert, sending a notification to a first device of the user reminding the user to wear the helmet, and sending a notification to a second device indicating that the user is using the bicycle without wearing the helmet.

摘要： The invention describes a procedure for determining the subsurface total organic content (TOC) from data obtained in the well by at least three well-logging tools measuring corresponding parameters. Three tools, namely sonic, density and deep resistivity are selected. The time interval signals from the sonic tool are converted to the P-wave velocity. The product of signals obtained from the sonic and density tools (P-wave velocity×Bulk density=Acoustic Impedance (AI)) responds in the same direction to a variation of the volume of water and organic matter (OM) volume of the rocks, whereas the third tool (Deep Resistivity) reacts very differently in response to a change of one or other of these same components, in a three-pole diagram, with rock matrix, OM and water as the three components onto an Acoustic Impedance vs resistivity ratio function plane. The resistivity ratio function is the square root of the ratio between the water resistivity and the measured formation resistivity. The position of the curved line with OM=0% by volume is fixed connecting the rock matrix pole with that of water pole. The slope of the matrix-water curve is controlled by the tortuosity factor ‘a’ that is a function of the rock pore structure, grain size and level of compaction. Iso-OM curves run parallel to this 0% OM reference curve. The data points to be analysed can be calibrated accordingly by changing the resistivity of water (Rw) and the tortuosity factor (a) parameters. In a graph where the parameters used depend, for example, on the sonic velocity in the rock, the rock bulk density and on the electric resistivity of the formations, the iso-OM lines form a set of parallel curved lines. The OM is derived from there corresponding to each pair of values of the parameters measured in the well. The obtained organic matter volume is converted to Total organic carbon (TOC) in gram percentage using a conventional relation.

摘要： A target detection device mounted in a vehicle includes: a radar specification unit; a same target determination unit; and an image specification unit that specifies, as image target position information, an image detection region of an image detection target detected on the basis of a captured image, the image detection region representing the position of the image detection target relative to the base point on an XY-plane with the X-axis representing the vehicle width direction of the vehicle and the Y-axis representing the vehicle length direction of the vehicle. The image specification unit sets the Y-axis range of the image detection region in the Y-axis direction on the basis of the bearing from the base point to each of the two X-directional ends of the image detection target in the captured image and of an expected width minimum value and an expected width maximum value in the X-axis direction.

摘要： A vehicle theft-prevention apparatus can include a locking mechanism with an engagement component. The locking mechanism can be engaged via a first action to apply a force on the vehicle when in an engaged state. The locking mechanism can disengage, via a second action, to withdraw the force from the vehicle when in the engaged state. The locking mechanism can maintain a current state of the force in response to the first action and the second action when in a disengaged state. One or more computing devices can receive a command to enable or disable the locking mechanism. In response to receiving the command, the computing device can cause the engagement component to transition the locking mechanism from the disengaged state to the engaged state or from an engaged state to a disengaged state.
