Interactive Sensor Technology

This section describes the functionality of the Interactive Sensor Technology (IST) feature on the MC9500-K.
The IST supports the following features.
•
Power Management – manage power by configuring IST to control switching on/off the backlight, control
suspend mode of the MC9500-K by monitoring motion and orientation.
•
Display Orientation – switch the screen orientation to either landscape or portrait depending on the
MC9500-K orientation.
•
Free Fall Detection – monitors free fall duration and records the time and type of the drop event.

Power Management

The MC9500-K orientation and motion sensitive data can be used as an indicator of MC9500-K usage and can be
used to manage the battery power of the mobile computer. For example, IST can be configured to control the
backlight on and off functionality or go into suspend according to a user gesture by placing screen facing down. It
can also be used to keep the MC9500-K active while it is in movement to prevent it from quickly going into suspend
mode while in use.

Display Orientation

The screen can be rotated between portrait and landscape modes automatically, depending on the physical
orientation of the MC9500-K. For example, if the MC9500-K is rotated 90° counterclockwise, IST rotates the
display counterclockwise 90° so that the screen display appears correct.
This functionality is achieved by monitoring screen angle and rotating the display to counter any changes. IST only
rotates the screen in multiples of 90°.

Free Fall Detection

IST continuously monitors gravitational force on the MC9500-K according to its current position. When the
MC9500-K free falls, IST detects the absence of gravitational force and records the event data if it detects a free
fall more than 450 ms, which may indicates nearly a one meter drop. This data can be used as an indicator of
potential abuse or misuse.
IST features a log for recording the free fall events. This log records the date, time and the time period of the free
fall.
