A potential drowning incident detection system and its constituent components are disclosed. The system includes a device worn on a head of a swimmer, which includes one or more signal generating units. The signal generating units may be positioned on the device adjacent each temple of the swimmer when worn. The system further includes at least one hub configured to receive wireless signals from the signal generating units, and may further be in communication with a server. The hub and/or server may generate an alert or warning when the signals of the signal generating units are not received by the at least one sensor hub. The alert or warning may further be triggered to a wearable device provided to a responder, such as a life guard. Data collected from the swimmer-worn devices may be stored for later analysis.

A button structure of a wireless transceiver and a manufacturing method thereof are provided. The button structure includes a housing, a first spring-back button, and a second spring-back button. The first spring-back button are integrally formed by double injection molding respectively. The first spring-back button and the second spring-back button are connected with the housing through insert injection molding. Thus, a manufacturer may produce the first spring-back button and the second spring-back button by a double injection molding machine in advance, and then combine the first spring-back button and the second spring-back button with the housing by the insert injection molding, so as to make the wireless transceiver with buttons of different colors.

A device localization system for a vehicle and a mobile device configured as a Phone-as-a-Key (PaaK) is described. The system includes a fob-free mode for performing remote control vehicle features using a selective mobile device localization technique that reduces motive functionality of the vehicle, based location of a user performing the vehicle control during the remote-control operation. The system determines a geographic position of a user using a single Bluetooth® Low Energy (BLE) antenna, and establishes establish a high-fidelity zone based on a change in mobile device position. The system reduces a motive functionality of the vehicle, based on the selective mobile device localization, from a first motive mode having a full motive functionality to a second motive mode responsive to determining that the mobile device is not present in the high-fidelity zone.

Methods for attaching a radio frequency (RF) transmitter to an animal are provided. The methods can include providing an RF transmitter and providing an injection device having a needle of gauge of 9 or smaller; providing the RF transmitter into the injection device; and providing the RF transmitter through the 9 gauge or smaller needle and into the animal.

A smart personal safety device includes a chemical irritant that may be dispersed by a user in the event of a threat by an attacker. The smart personal safety device includes an alert signal sent when the user activates the smart personal safety device, sending an alert signal to a mobile device for security alert management by software contained on the mobile device.

Disclosed is a portable communication device including a housing, a printed circuit board seated in the housing and mounted to a communication circuit, and a least one position adjusting groove, wherein the housing includes a support plate having at least one antenna unit operatively connected with the communication circuit, and an injection molded member surrounding at least a portion of the at least one antenna unit, wherein the support plate includes a main body in which at least a portion of the printed circuit board is seated, and at least one lead connecting the at least one antenna unit with the main body, and wherein the at least one position adjusting groove is formed at a position at which the at least one lead makes contact with the injection molded member.

An operating device for a human-powered vehicle comprises a base member and circuitry. The base member includes a power-supply accommodating part configured to accommodate a power supply extending along a reference plane. The circuitry is provided to the base member to extend along an additional reference plane intersecting with the reference plane.
