A device, system and method for crowd control is provided. An aural command is detected at a location using a microphone at the location. A computing device determines, based on video data received from one or more multimedia devices, whether one or more persons at the location are not following the aural command. The computing device modifies the aural command to generate a second version of the aural command based on one or more of the video data and multimedia data associated with the location. The computing device causes the second version of the aural command to be provided, to the one or more persons who are not following the aural command at the location, using one or more notification devices.

A computing device may receive an indication of an audio signal captured by a microphone, wherein the audio signal includes voice input. The computing device may determine that the voice input in the audio signal is from an authorized user of the computing device and includes a trigger phrase associated with a request to trigger device finder functionality based at least in part on comparing the voice input with data provided by the authorized user of the computing device. The computing device may, in response to determining that the voice input in the audio signal is from the authorized user of the computing device and includes the trigger phrase associated with the request to trigger device finder functionality, cause a speaker of the computing device to audibly output the alert sound to assist the authorized user to locate the computing device.

Aspects discussed herein relate to providing alerts to a community of devices located in or near a geographic area such as a building or property. The alerts override any alert-inhibiting state of the mobile device to deliver audio, visual, and/or haptic alerts in emergency situations. The communication and emergency alert system may be used to communicate with many different communities of people. Moreover, certain individuals may be members of more than one community at the same time, and the communities themselves may change over time based both on the user's preferences and on their physical locations. Users may set their own preferences for how alerts are provided, such as customizing the visual and/or audible notifications provided for an alert.

Techniques and methods for wirelessly communicating with equipment such as, but not necessarily limited to, automatic swimming pool cleaners (APCs) are detailed. An accelerometer or other sensor on-board an APC may recognize such communications. In some cases, varying operation of a motor or other feedback generator of the APC may provide sonic or other feedback in response to the communications.

An information transmission system includes a bell, a transmitter, a manual actuator that is manually operated by an operator and actuates the bell, and a controller having a sensor and a memory, wherein the controller analyzes operation information of actuation of the bell actuated by the manual actuator based on an output from the sensor and stores the operation information to the memory, and wherein the transmitter determines operator information corresponding to the operator in the operation information recorded in the memory when the operator rings the bell, and sends the determined operator information.

Disclosed herein are various devices, systems, and methods for use in agricultural, particularly for use in harvesting agricultural crop such as corn. Various implementations relate to devices, systems, and methods for increasing yield by emitting warnings when the corn head to not at the proper height.

Disclosed herein are various devices, systems, and methods for use in agricultural, particularly for use in harvesting agricultural crop such as corn. Various implementations relate to methods and devices for measuring plant stalk cross-sectional area during harvest and providing additional methods of predicting and displaying yield on a row-by-row level in real time.

Disclosed is a system for generating alerts communicated to emergency responders and/or contacts indicating a location of an incident. The system comprises a housing, one or more light sources, and a computing processor. A switch is located in the housing and configured to be accessible to a user. When the switch is actuated by a user indicating an incident, the processor provides power to the at least one light source to output light from the housing thereby indicating the location of the system. The system may also control a speaker to output an audible signal and a transmitter to transmit an emergency signal with location information to a device of an emergency responder and/or an emergency contact. The present invention may also be embodied in a software application that is implemented on a mobile device to thereby leverage the components of the mobile device to send alerts.
