An emergency notification system for a building is provided. The emergency notification system includes one or more inputs devices mounted throughout the building. The one or more input devices can be configured to receive a manual user-input. The emergency notification system can include one or more output devices mounted throughout the building. The one or more output devices can include a plurality of LED arrays. Each of the plurality of LED arrays can be configured to emit light of a different color to indicate a different type of emergency. The emergency notification system can include one or more control devices configured determine a type of emergency occurring within the building based on the manual user-input. Furthermore, in response to determining the type of emergency, the one or more control devices can activate one of the LED arrays to emit light of a color indicative of the type of emergency.

An electronic device includes a processor, and a memory containing instructions that, when executed by the processor, cause the electronic device to learn a sound emitted by a legacy device and to issue an output when the electronic device subsequently hears the sound. For example, the electronic device can receive a training input and extract a compact representation of a sound in the training input, which the device stores. The device can receive an audio signal corresponding to an observed acoustic scene and extract a representation of the observed acoustic scene from the audio signal. The electronic device can determine whether the sound is present in the observed acoustic scene at least in part from a comparison of the representation of the observed acoustic scene with the representation of the sound. The electronic device emits a selected output responsive to determining that the sound is present in the acoustic scene.

A system for proximity-based analysis of multiple entities includes a first communication device associated with a first entity and an additional communication device associated with an additional entity, wherein the first communication device and the additional communication device are communicatively couplable. The system includes one or more processors communicatively coupled to at least one of the first communication device or the at least an additional communication device. The one or more processors are configured to: identify a spatial relationship between the first entity and the additional entity based on one or more signals from the first communication device or the additional communication device, identify an operation unit defined by an association between the first entity and the additional entity based on the spatial relationship between the first entity and the at least the additional entity, and report one or more characteristics of the operation unit.

A system and method of monitoring sobriety using a handheld breath testing device that, on receipt of a user's breath, generates a breath test signal comprising substance content data and user identification data, and wirelessly transmits the breath test signal to a breath test signal receiving station, and wherein the breath testing device further includes a fingerprint reader and a plurality of sensors.

In one embodiment, a system includes an interface and a communicatively coupled processor. The interface is configured to receive first future location information of a first user and receive second future location information of a second user. The processor is configured to determine that the first and second future location information each correspond to a future location and determine that a characteristic related to the first user corresponds to a preference related to the second user. In response to these determinations, the processor is configured to cause information to be presented to the second user, the information to be presented to the second user comprising the future location and that the first user and the second user have the future location in common.

A device may receive frames of a video capturing an analog meter with a dial and a needle, may process the frames to identify a center, a radius, and a perimeter of the dial, and may determine calibrated values for the dial. The device may apply a model to one of the frames to create a base mask, may apply thresholding for a dynamic HSV bounding value, to the base mask and the frames, to create masked frames, and may identify contours for the masked frames. The device may identify a quantity of points for each of the contours, may estimate angles of the needle of the analog meter based on the quantity of points, and may average the estimated angles to determine an averaged needle angle. The device may determine a needle direction based on the averaged needle angle and may calculate a meter reading.

One example method of operation may include identifying an emergency location based on a received emergency communication, determining enhanced information is available in a memory for the emergency location, retrieving the enhanced information, and forwarding the enhanced information to one or more emergency service entities and one or more registered devices located at the emergency location.

Techniques are disclosed for adjusting a transmission frequency of a physiological monitoring unit, which includes a capture unit and a receiver unit. The capture unit and the receiver unit are wirelessly connected together and are configured to exchange data on the transmission frequency by means of a programming unit.
