A programmable signal generator and radio controller for providing dispatch paging tone out frequencies to first responders and other selected areas. The signal generator is capable of performing tone-outs to various first responders and being cross compatible with prior and future evolutionary systems. The signal generator uses plain-text console interface and plain-text tone-out parameter definitions allowing programming without special software, apps, or Internet connectivity. The signal generator is capable of controlling operational functions of connected radio transceiver equipment including initiating and terminating RF transmission, selecting radio channel or frequency, and monitoring operational status of the transceiver. The signal generator is also capable of interactive communication with external third-party digital radio dispatch console systems via Ethernet network and TCP/IP protocol via an isolated network interoperability interface that implements a simple Application Program Interface (API).

A smart crosswalk safety system for a pedestrian comprises bollard devices disposed in a sidewalk, each bollard device including a pedestrian identification sensor detecting a pedestrian, a camera photographing an area including the crosswalk, a beacon device transmitting a beacon signal toward the crosswalk when an operation signal is received from a control device, the control device generating an operation signal to drive the beacon device when the bollard device identifies a pedestrian who walks from the sidewalk toward the crosswalk and a pedestrian is identified to be present in the pedestrian identification area of an image captured by the camera, and a lock screen application installed in the pedestrian terminal of a pedestrian who crosses a street at the crosswalk to change screen of the terminal to a locked state when a beacon signal is received.

A wearable reminder or gesture control device is provided using two different types of gestures obtained from two different types of sensors. The device outputs audio to a user but does not have a display, a keypad, or speech recognition software, therewith significantly reducing size, storage requirements and power consumption. Hence the device is suitable for use by the blind, persons with a speech impediment, visually impaired persons, and others who are unable to read small fonts.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating verbal message. One of the methods includes: receiving sensor data indicating attributes of a person at a physical property; determining, using the sensor data, that a likelihood that a conversation should be initiated with the person satisfies a first likelihood threshold; determining, using first data from the sensor data, a deterrence strategy with a second likelihood threshold of causing the person to leave the physical property; generating, using second data from the sensor data and the deterrence strategy, a verbal message that is a) for the person and b) has the second likelihood threshold; and providing, to a presentation device, a command to cause the presentation device to present the verbal message.

In one embodiment, an underground communication system is described. The system includes a low to medium frequency transmitter and a plurality of receivers. The transmitter comprises an output coupler and a signal selection unit. The transmitter is operable to generate a low to medium frequency signal. Each of the plurality of receivers includes an antenna and at least one sensory output unit. The plurality of receivers is configured to detect a low to medium frequency signal.

Embodiments of the present invention relate to a wireless emergency bell and a method for controlling a wireless emergency bell installed in a school and a school zone, the method comprising the steps of: receiving an input signal generated by pressing a provided button by a reporter when an emergency situation occurs; generating an emergency bell signal, repeatedly transmitting the generated emergency bell signal to at least one pager and a receiver during a predetermined configuration time, and outputting a prestored alarm sound to the outside through a provided speaker; generating an emergency bell voice signal and transmitting the generated emergency bell voice signal to the at least one pager and the receiver; generating an emergency bell voice transmission completion signal indicating that the emergency bell voice signal has been completely transmitted, and transmitting the generated emergency bell voice transmission completion signal to the at least one pager and the receiver; converting an operation of the wireless emergency bell into a reception mode in which data can be automatically received from at least one pager after a configured time; receiving a pager voice signal from the at least one pager; determining whether the received pager voice signal exists, and outputting the received pager voice signal to the outside through the speaker when the received pager voice signal exists; and determining whether a mode conversion command signal is received from the at least one pager when the received pager voice signal does not exist, and converting the operation of the wireless emergency bell into a transmission mode in which data can b e transmitted to the at least one pager and the receiver when there is the received mode conversion command signal.

The present invention relates to a maritime distress signal transmission device which transmits a distress signal to an arbitrary rescue station to rescue a person in distress by transmitting a distress signal of the person in distress at sea wearing a life jacket and precise location information based on the Global Positioning System (GPS) to the rescue station as audible sound, and the maritime distress signal transmission device includes a holder-cradle which is coupled to the life jacket of the person in distress by a clip and a main body which is coupled to the holder-cradle and transmits the rescue signal to an arbitrary receiver using a preset frequency band.

A sounding device having a notification function, a data analysis notification system, and a data analyzing method the thereof are disclosed. The sounding device is used to establish a connection with an electronic device. The sounding device includes a sensing module, a data analysis module, a communication module, and a sounding module. The sensing module is used for sensing a sensing data. The data analysis module is used for analyzing the sensing data, wherein when the sensing data exceeds a threshold, a notice signal is generated. The communication module is used for transmitting the notice signal to the electronic device and receiving a voice signal returned from the electronic device, thus the sounding module is allowed to output the voice signal.

A method and a device for alarming with a terminal, and a storage medium are provided. According to an example of the method, upon acquiring current parameter information of the terminal, it is possible to determine whether the parameter information satisfies a preset condition or not. When the preset condition is satisfied, alarm information may be output.
