2.3 Body Pack (BP), Battery Pack, and Access Point (AP)

Figure 4: Body Pack (BP)

Figure 4 shows the Body Pack (BP). The strings

of MTx’s are interconnected by the Body Pack. It

delivers power from the battery pack to the

connected MTx’s and retrieves their data

ensuring exactly synchronized samples.

For more information about the Body Pack, see

Section 5.3.

Figure 5: Access Point (AP)

Figure 5 shows the Access Point. The Access

Point pairs with the Body Pack to handle the data

traffic between the BP and the computer. This

Access Point connects to the PC or laptop via

Ethernet cable or wirelessly and is powered using

a proprietary power adapter or laptop battery.

One Access Point can connect to multiple MVN

systems. For more information about the Access

Point, see Section 5.6.

Figure 6 Battery Pack (Battery)

Figure 6 shows the Battery Pack, which connects

to the Body Pack via the Battery Cable. The

Battery Pack is a single unit made up of 3 Lithium

Ion rechargeable cells, and has a typical rating of

10.8V and 2.9Ah. This Battery charges via a

single bay standard smart charger and provides

up to 9.5 hours of continuous recording time to

the system.

2.4 Cabling

While transmission from the subject to the PC is completely wireless, there are a number of cables

running through the MVN Link suit, connecting the MTx and MTx-STR’s to the Body Pack. Additionally,

if the user chooses, there is the option of transmitting motion data to the PC from the BP by directly

using an Ethernet cable between the Body Pack and the Access Point. This is particularly useful for

applications such as skiing or snowboarding, where the wearer of the suit can connect directly to a

laptop carried in a backpack.
