A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As another example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.

A wearable monitoring device for securely remaining coupled to a user and recording data pertaining to the user is provided. The device includes a main body, which has a display for viewing, a magnet for aligning the main body to other objects, a rechargeable battery for powering the main body and a computing module for storing, transferring and analyzing data. The device also includes a band extending from a first end of the main body to a second end of the main body for permitting coupling of the device to a user. The band may include anti-tampering features for preventing uncoupling of the device from a user without detection

A system for notifying occupants of a structure that a pet is proximate to an opening of a structure. The system may include a pet unit wearable on the pet's body and including a transmitter configured to transmit a wireless proximity signal from the pet unit. The system may further include an exit unit positionable at an exit of the structure. The exit unit may include a receiver configured to receive a said wireless proximity signal transmitted by a pet unit, with the receiver being configured to produce an alert signal when a said wireless proximity signal is received. The exit unit may also include an alerting assembly configured to provide a presence alert when the receiver receives a said wireless proximity signal. The alerting assembly may comprise a perceptible alerting mechanism configured to produce a perceptible presence alert which is perceptible to a sense of a human.

Provided is a work machine capable of eliminating the inconvenience from the operator of the work machine as much as possible while deterring a contact between the work machine and workers, and suppressing a decrease in productivity of the work machine. A work machine 5 includes: an identification information recognition device 41 configured to recognize identification information on a person who enters a predetermined region R around the work machine 5; and a controller 7 configured to control the work machine in accordance with the identification information. When a person enters the predetermined region R under the condition that the work machine 5 is ready for operation, the controller 7 counts the number of times the person enters the predetermined region R as the number of approaches for each person distinguished with the identification information, and controls the work machine 5 based on the counted number of approaches in accordance with the identification information of the person who is in the predetermined region R.

A cargo alerting system that is self-arming. Placing a child in a car seat having sensors arms the system. A keyfob, or smartphone, which is carried by the user, outputs an alarm when the keyfob is moved farther than a pre-determined distance from the base, which may be in the car seat, or otherwise connected to a child in the vehicle. This preset distance could be any desired distance. The keyfob and alarm refocus the user's attention on the cargo within the vehicle.

A system for serving legal documents for initiating legal proceedings which includes a repository, the form of a database which is stored on a server (not shown), for receiving and storing legal documents for initiating legal proceedings, a notification means, in the form of a notifier, for notifying a recipient via an agreed digital address (not shown) of receipt by the database of a legal document, and a payment means (not shown) for allowing the recipient to access the legal document free of charge.

A monitoring system and related methods are disclosed. The system has a first apparatus associated with a living target, a second apparatus associated with a protected individual, and a third apparatus associated with a community individual. The first apparatus has a lock for fixing the first apparatus to the living target, a tamper-evidencing mechanism, mechanisms for monitoring a GPS location of the first apparatus, determining the first apparatus is within at least one of a first threshold distance from the second apparatus or a first threshold distance from a pre-set GPS location, warning the living target responsive to the determining the first apparatus is within the at least one of the first threshold distance from the second apparatus or the first threshold distance from the pre-set GPS location, determining the first apparatus is in a banned location, and emitting a debilitating sound.

Systems and methods for providing a health monitoring and emergency response service are provided. Each element in a plurality of data elements is obtained from a health monitoring device connected to a corresponding subject in a plural of subjects. An alert is triggered through analysis of the data element or manually triggered by the subject or a subject's circle of support. The subject or one or more members of the circle of support of the subject verifies or rejects the alert. The alert is sent to a remote monitoring alarm center and emergency responders are dispatched.

A system for alerting a user when a preset distance between any of a plurality of wireless transceiver devices or a secondary client device such as a smartphone is achieved. Each of the wireless transceiver devices are pairable to each other and to the secondary client device. Each of the wireless transceiver devices may be placed on or worn by a person or object to be tracked. Once a preset distance is achieved between any of the wireless transceiver devices or between any of the wireless transceiver devices and the secondary client device, each of the wireless transceiver devices is configured to alert the user that the preset distance was breached. The system may employ a software application for coordinating the system and tracking separation and other related data collected by each of the wireless transceiver devices.

A monitoring unit for wireless communication with a plurality of self-contained breathing apparatus (SCBA) units configured to form a network is provided. The monitoring unit includes a communication interface and processing circuitry. The processing circuitry is configured to receive, via the communication interface, a plurality of updates from each of the SCBA units where each update includes information indicating at least one communication link quality to at least one other SCBA unit. The processing circuitry is further configured to determine at least one distance from each SCBA unit to at least one other SCBA unit that is one hop away in the network based at least in part on the communication link quality. The processing circuitry is further configured to cause the determined at least one distance to be displayed.
