Optimized power management for unfailing power supply

 

Power management is critical to infantry operations. Dismounted soldiers rely on a complex digital system that requires high levels of energy. Efficient management of power supply, distribution and sourcing is therefore key.

 

Fischer KEYSTONE™ has been specifically designed to reduce the physical, cognitive and logistic burden faced by soldiers who need to stay focused on their mission without carrying multiple batteries or constantly worrying that devices are correctly powered and charged throughout the duration of the mission.

 

The Fischer KEYSTONE™ multiport hub and cable assembly solutions enable soldiers to power their devices through a central battery, optimizing resource management for lighter combat gear.

 

With the SMBus technology, the Fischer KEYSTONE™ hub monitors battery state of charge and operating time, while the user manages the system’s energy flow on the EUD power management app. The individual PANs’ energy consumption can be independently monitored and controlled for better efficiency.

 

 

Nett Warrior compatible connectors

 

Compatible with components and standards such as Nett Warrior, NATO STANAG 4695, 4851 and GOSSRA, the Fischer UltiMate™ 80 connector has been engineered to offer ultra-rugged, lightweight and IP68-sealed connectivity solutions.

Software application

Fischer_Keystone_software_application_section_pic
FISCHER KEYSTONE™ 6 SOFTWARE KEY FEATURES
  • All-in-one use through Android power management app with seamless ATAK integration
  • Independent port power and data management
  • Security through only booting signed software – SHA256 checksum and ECC256 signature
  • AES 256 encryption and FIPS 140-2/3 compliance
  • API interface for specific software development and integration

The Fischer KEYSTONE™ system software has been designed to provide an easy-to-use all-in-one application to manage the power and data flows of all worn devices, enhancing the situational awareness and efficiency of soldiers at every level of their mission in the field.

 

The Android power management application delivered by the Fischer KEYSTONE™ software comes as a standalone app and/or as a plug-in seamlessly integrated within the industry standard ATAK (Android Team Awareness Kit), the leading battlefield awareness software application known to dismounted soldiers, Fischer Connectors’ customers and Soldier Modernization programs.

 

The app or plug-in serves as a single, centralized PAN management application with an easy-to-read GUI on the soldier EUD – smartphone or tablet. It allows soldiers to quickly and easily monitor battery charge and system status, independently control power and data for each port of the Fischer KEYSTONE™ hub, and manage the power and data flows of all interconnected peripherals and devices – without switching between different apps or leaving the ATAK environment. This reduces the risk of distraction, and soldiers stay focused on their mission.
