Systems and methods are introduced for rate control of data transmissions in a wireless camera system. In an illustrative embodiment, a computing system selects primary data rates and corresponding fallback data rates to use for transmission of video data. The computing system selects the data rates that provides high-throughput without resulting in wasted energy from retransmissions. The selection may be based upon transmission conditions as well as the record of past data rates, the number of attempts for the data rates, and whether they were successful. These data may be stored as a state machine or for machine learning analysis. Finally, the video data may be aggregated prior to transmission to reduce overhead and improve efficiency.

A smart speaker system is used as an emergency notification system. The smart speaker has a loudspeaker, a microphone, a visual display, processing capability, and an emergency flasher in the same enclosure. The smart speaker is in communication with a network-connected server providing at least distribution of emergency notification messages to appropriate clients. The amount of audio processing shared between the smart speaker and the server may vary, depending on the requirements of the installation site. Once an emergency voice communication is detected in the microphone output, the system generates a confirmation message that is played over the loudspeaker. Upon detection of an appropriate voice response from the user, the system generates an emergency response message, sends it to the distribution network, and activates the visual display, loudspeaker, and emergency flasher. Noise cancellation circuitry prevents loudspeaker interference with microphone output.

A caregiver badge system includes a caregiver badge configured to be worn by a caregiver and having a cavity defined therein. An identification badge is configured to be positioned within the cavity. The identification badge is removable from the caregiver badge. A transceiver is positioned within the caregiver badge and configured to communicate with a positioning system to identify a location of the caregiver. A battery is positioned within the caregiver badge to power the transceiver.

Systems and methods for welding are described. The welding system can include, for example, a welding power source, a welding torch, and a computer. The computer and the welding torch can be operatively coupled to the power source. A first weld is performed and its signature is saved by the computer. It is considered a high quality weld and is selected as a weld reference. A second weld is performed and its signature is saved by the computer. The computer then computes a single weld confidence result for the second weld based on a comparison between the signature data of the second weld and the signature data of the reference weld. A weld fault condition is triggered based on the single weld confidence result which causes the welding system to stop or to modify the welding operation, and/or which causes the welding system to send out communications relating to the triggering of the weld fault condition.

A security system includes an individual subscriber unit, an emergency alarm device proximate to a location frequented by people, and a control system configured to a) receive an emergency alert message from the individual subscriber unit, b) receive an emergency stand-down message from the individual subscriber unit, c) automatically transmit an emergency alert signal in response to the control system receiving the emergency alert message from the individual subscriber unit, and d) automatically transmit an emergency stand-down signal in response to the control system receiving the emergency stand-down message from the individual subscriber unit. The emergency alarm device is operatively coupled to the control system for automatically activating for issuing an alert for warning people at the location that an emergency is present, in response to the emergency alert signal, and automatically deactivating for terminating the alert, in response to the emergency stand-down signal.

This Wireless Safety Temperature Sensing Alarm is a thermally actuated alarm designed to send a wireless signal to a remote base which will turn on a buzzer, a visual light signal or an emergency alert system to alert anyone around that a child/person/pet/plant has been left in a confined environment that is experiencing extreme temperatures, whether hot or cold. It can also simply alert someone that a certain device or environment has reached the user defined set point temperature. It consists of 2 units: a base and a remote. The base is easily installed on any kind of carrier or as a standalone fixture, and it is designed to sense the temperature of the environment that the child/person/pet/plant is in and it can trigger a wireless signal on the remote to turn on the buzzer/alarm, and a flashing light for people who are hearing impaired or send an RF signal emergency alert. It's designed with a 10 minute turn-on delay to prevent false alarms upon startup. It also has a low-battery alert as an add-on safety precaution. The remote can be easily carried on or as a standalone device, or is easily installed on the exterior of the confined environment which the child/person/pet/plant is in. This makes it possible for anyone who is nearby to hear/see the alarm and take action. Many lives of children, beloved people, pets, and plants could be saved (and financial loss or wasted time could be prevented) using this easy to install invention. A future development of the product will be able to alert an emergency system in case that human lives are in danger of extreme temperatures.
