Wearsafe

Wearsafe is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wearsafe rather than just read about it. In short: Wearsafe is an American personal safety company located in Hartford, CT. Their primary wearable technology is a device that uses bluetooth technology to connect a button-like Tag with a smartphone app.

Key takeaways

Wearsafe belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wearsafe to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wearsafe from memory before moving on to harder problems.

Reference excerpt

Wearsafe is an American personal safety company located in Hartford, CT. Their primary wearable technology is a device that uses bluetooth technology to connect a button-like Tag with a smartphone app. When pressed, the Tag alerts a user's selected network of the location of the emergency, as well as sending a live audio feed of the incident to a group chat function.

History Wearsafe was created in response to the Cheshire Home Invasion Murders of 2007. The founders, David Benoit and Phillip Giancarlo, began work on the technology in 2011 with copatent providers Rick Borden, Kyle Busque and Keven Busque.

Tag The Wearsafe Tag is a small, wearable button that operates similarly to other wearable personal safety devices: by connecting to a smartphone. The device also works without a smartphone, but is limited to 200 ft (70 m) from the location. According to the Boston Globe, "Activating the Wearsafe tag not only triggers a set of alerts sent to a designated list of contacts, but sends live location information and audio from the scene and opens a 'virtual situation room' between respondents in order to coordinate help (or call 911). The 'Rewind' function [plays] audio recorded in the 60 seconds prior to activation to provide context. Whatever action taken on a call for distress, the tag vibrates the reassure the caller that help is on the way: The Wearsafe Tag buffers live audio whenever it is turned on.

App Wearsafe's Tag pairs with a mobile app to connect with the user's selected network. The Wearsafe Tag sends GPS coordinates and audio context to a prearranged network set up through the app. The app provides reassurance to the victim that help is on the way-- which Secret Service Agents, Navy SEALS, and CIA Agents "pointed out that people who have reassurance that help is on the way have a much, much higher probability of a successful outcome in a stressful situation."

Worked examples

Example 1 — a first encounter with Wearsafe

Start with the simplest possible case. Write down what Wearsafe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wearsafe before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wearsafe ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wearsafe

In research: Wearsafe appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wearsafe in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wearsafe is common in secondary-school and first-year university syllabi. It links to neighbouring topics Wearable devices, so understanding it makes those chapters shorter.
In everyday life: Look for Wearsafe outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Wearsafe in simple terms?

Why does Wearsafe matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Wearsafe?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
