Key Finder
Key finders, also known as keyfinders, key locators, or electronic finders, are small electronic devices fitted to objects to locate them when misplaced or stolen, such as keys, luggage, purses, wallets, pets, laptop computers, toddlers, cellphones, equipment, or tools, and to transmit alerts, e.g., that one's restaurant table is ready or a nurse is needed. Some key finders beep or flash lights on demand. Types Sound-based Early models of key finder were sound-based, and listened for a clap or whistle (or a sequence of same), then beeped for the user to find them. Determining what was a clap or a whistle proved difficult, resulting in poor performance and false alarms. Because of this low quality and unreliability, these early key finders were soon discarded and were unpopular for serious needs. Radio As electronics became smaller and cheaper, and battery life improved, radio became viable to locate the keys, which were fitted with a small receiver. A separate transmitt ...

TrackR
TrackR was a commercial key finder that assisted in the tracking of lost belongings and devices. Trackr was produced by the company Phone Halo and was inspired by the founders' losing their keys on a beach during a surfing trip. The founders of Phone Halo began working on TrackR in 2009. In 2010, they founded the company and launched the product. In Winter 2018, TrackR rebranded itself to Adero, as part of changing its focus to other uses for its tracking technology, taking TrackR beyond the Bluetooth fobs that had been the core of its service. TrackR shut down its services and removed its apps in August 2021. Overview The device contains a lithium battery that needs to be changed about once a year by the user. It communicates its current location via Bluetooth 4.0, to an Android 4.4+ or iOS 8.0+ mobile device on which the TrackR app is installed and running. This feature is referred to as "Crowd Locate", since each device will report its location to all other TrackR devices ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Location-based Service
Location-based service (LBS) is a general term denoting software service (economics), services which use geographic data and information to provide services or information to users. LBS can be used in a variety of contexts, such as health, indoor object detection, object search, entertainment, work, personal life, etc. Commonly used examples of location-based services include navigation software, social networking services, location-based advertising, and tracking systems. LBS can also include mobile commerce when taking the form of coupons or advertising directed at customers based on their current location. LBS also includes personalized weather services and even location-based games. LBS is critical to many businesses as well as government organizations to drive real insight from data tied to a specific location where activities take place. The spatial patterns that location-related data and services can provide is one of its most powerful and useful aspects where location is a ...

Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs Ultra high frequency, UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones, wireless speakers, HIFI systems, car audio and wireless transmission between TVs and soundbars. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The Institute of Electrical and Electronics Engineers, IEEE standardized Bluetooth as IEEE 802.15.1 but no longer maintains ...

AirTag
AirTag is a tracking device developed by Apple. AirTag is designed to act as a key finder, which helps people find personal objects such as keys, bags, apparel, small electronic devices and vehicles. To locate lost or stolen items, AirTags use Apple's crowdsourced Find My network, estimated in early 2021 to consist of approximately one billion devices worldwide that detect and anonymously report emitted Bluetooth signals. AirTags are compatible with any iPhone, iPad, or iPod Touch device capable of running iOS/iPadOS 14.5 or later, including iPhone 6S or later (including iPhone SE 1, 2 and 3). Using the built-in U1 chip on iPhone 11 or later (except iPhone SE and iPhone 16e models), users can more precisely locate items using ultra-wideband (UWB) technology. AirTag was announced on April 20, 2021, made available for pre-order on April 23, and released on April 30. History The product was rumored to be under development in April 2019.

Bluetooth Low Energy
Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries. Compared to Classic Bluetooth, Bluetooth Low Energy is intended to provide considerably reduced power consumption and cost while maintaining a similar communication range. It is independent of classic Bluetooth and has no compatibility, but Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and LE can coexist. The original specification was developed by Nokia in 2006 under the name Wibree, which was integrated into Bluetooth 4.0 in December 2009 as Bluetooth Low Energy. Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as macOS, Linux, Windows 8, Windows 10 and Windows 11, natively support Bluetooth Low Energy. ...

Mobile Phone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Device
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. It is a subfield of physics and electrical engineering which uses active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signals to digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in response to global demand. The semiconductor industry is one of the gl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
