A monitoring system for an agricultural sprayer includes a spray nozzle, a pressure sensor, a flow rate sensor, and control circuitry. The spray nozzle is configured to generate a spray of a fluid, the pressure sensor is adjacent to the spray nozzle and is configured to measure a pressure of the fluid sprayed by the spray nozzle, and the flow rate sensor is adjacent to the spray nozzle and is configured to measure a flow rate of the fluid sprayed by the spray nozzle. The control circuitry is configured to receive the measured pressure from the pressure sensor, receive the measured flow rate from the flow rate sensor, and cause a user interface to display the measured pressure and the measured flow rate. Related methods and systems are also disclosed.

Apparatus to secure an Automated Teller Machine (ATM) or other structure are disclosed herein. One apparatus includes an arm including an attachment and a lockpin that engages the attachment in an engaged position. The lockpin is configured to prevent the arm from disengaging from the engaged position when a force is applied to the arm. Another apparatus includes an arm including an attachment that prevents rotation of the arm, a lockpin that engages the attachment in an engaged position, and a lock connected to the lockpin to prevent releasing the lockpin from the engaged position. An ATM includes a frame, a gate, and an abutment. The gate includes an arm including an attachment that locks the arm. The abutment includes a lockpin that engages the attachment in an engaged position to prevent the arm from unlocking and a lock connected to the abutment to prevent access to the lockpin.

A device for monitoring temperature of a beverage and for communicating data, the device comprising: a housing portion configured to be oriented adjacent to a drink in a drink sleeve; a thermal sensor coupled to said housing portion and oriented to take temperature readings of the drink in the sleeve; and a wireless transceiver coupled to said thermal sensor and configured to transmit data representative of a temperature condition.

A submersion sensor for detecting submersion in a fluid is disclosed. The submersion sensor includes at least one float member and at least one sink member. The submersion sensor includes force sensors positioned at distal ends of each of the at least one float member and the at least one sink member. Further, the submersion sensor includes a controller. The controller determines submersion of the submersion sensor upon obtaining signals from the force sensors corresponding to opposite directional movement of the at least one float member and the at least one sink member in the fluid.

A method includes receiving, at an insurance provider server and from at least one sensor located at an insured property, sensor data indicative of an insurance risk associated with the insured property. The method also includes determining, based at least in part on the received sensor data, a risk-adjusted insurance premium for an insurance account associated with the insured property. The risk-adjusted insurance premium compensates for the insurance risk associated with the insured property.

An electronic having a sensor, a display including a first area and a second area, and a processor electrically connected to the sensor and the display. The processor acquires information on an external object through the sensor, determines the importance of the external object through the information, and controls the display to display at least one augmented reality object or at least one virtual reality object in the first area in response to at least one of determining that the importance is less than a first importance and that the information on the external object has not been acquired. The processor also controls the display to display an indicator in the second area so that the indicator has a first size and removes at least a part of the at least one augmented reality object or the at least one virtual reality object according to priorities.

Methods of operating a refrigerator appliance are provided. The refrigerator appliance includes a cabinet defining a food storage chamber with a drawer slidably mounted within the food storage chamber. The refrigerator appliance also includes a sensor operable to detect an atmospheric condition within the food storage chamber of the drawer and a camera assembly positioned and configured for monitoring the drawer. The methods generally include obtaining an image using the camera assembly and analyzing the image to identify a first food item and a second food item in the food storage chamber of the drawer.

An electronic tag includes an electronic tag body. The electronic tag body includes a housing, a display screen configured to display information, and a sensor and a main controller that are disposed inside the housing. The sensor is configured to detect an ambient temperature of an environment in which the electronic tag body is located. The main controller is configured to shut off power supplied to the display screen in response to the ambient temperature detected by the sensor being beyond an operating temperature range of the display screen.

Systems and methods for monitoring and suppressing a back EMF generated by an ESP motor when the ESP system is moved in a well. Embodiments provide both electrical braking to reduce the rotation of the motor (and corresponding back EMF) and warnings to alert users to hazardous conditions caused by the back EMF. One embodiment includes an ESP system having a permanent magnet motor, a back EMF safety system, and a power cable connected between them. The proximal ends of the cable's conductors are connected terminals of the back EMF safety system, which has switches that are closed to short circuit the conductors so that back EMF currents from rotation of the motor induce electrical braking in the motor. Currents and phase-to-phase voltages on the conductors are monitored to detect overcurrent and overvoltage conditions that may trigger alarms or other actions.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.
