Booting a Tab 4 while using STS and Kiosk

One of the main quirks when integrating a Samsung Tab 4 with any of our STS products (or Kiosk enclosures) has to do with booting up a Tab 4 from a power off state.

Samsung’s design of the Tab 4’s internal boot sequence is such that both charging and booting end up being disabled whenever a Tab 4 detects the appropriate single from an STS device (or Kiosk enclosure) to indicate SimulCharge Mode.

For our STS products this issue could be resolved by disconnecting the Tablet and either charging it for a bit or powering on the Tablet before reconnecting it. However for a Kiosk solution (which is often connected all the time) this really isn’t a feasible option. Since disabling of booting and charging is only an issue when the Tablet is in SimulCharge Mode we’ve managed to overcome this quirk by implemented a “Mode Select” button which provides the ability to toggle between SimulCharge and ChargeOnly Mode on the fly.

Phone-Fuze is Born – Successfully I might add on Tuesday, Feb 21, 2017

Interesting meeting today – it was kind-of a mix of marketing and engineering.  The meeting was really about sorting out the confusion (internal and probably mostly limited to me) wrt the new products based on our RBM (Reset, Battery Modulation) technology. I won’t get into an explanation of RBM here – that’s for another person/time/place.  In the end the meeting resolved a huge question and that is what to do with what we have internally called “Charge-Buddy”.

I guess, before I go on with the meeting “story”, I need to explain what “Charge Buddy” is/was. (it should have been and maybe is explained many times over in other blog entries but….).

Lithium-Ion Battery used by Tablets

Most mobile devices (including tablets) currently use built-in Lithium-ion rechargeable batteries. These batteries have a high energy density, minimal memory effect, and low self-discharge.

When using replaceable Lithium-ion batteries, only use a battery charger designed for this type of battery. Charging a Lithium-ion battery with the wrong charger can damage the battery, result in a fire, or cause the battery to explode.

The Lava Blog –My “Excuse” or rather “Reason” why I think it should exist

They say that sometimes the present is the best time to start something. Especially if that something has been dreamed/thought of for much longer than is necessary.  I guess this blog falls into such a category.

What am I trying to achieve in this blog and why do I think Lava should have one?
