Frequently Asked Questions About PAMSys™

Each PAMSys motion sensor is shipped with an AC charger (standard US plug) and a chest strap. Orders of 4 or more motion sensors are shipped with a charging station capable of charging up to 5 motion sensors simultaneously. PAMSys software (PAMWare) is sold separately.

PAMWare is supported for Windows XP and newer. PAMWare is not supported for Mac. Minimum system requirements are a 2.8GHz processor and 2GB RAM. PAMWare is not compatible with ultra high resolution displays (e.g., Apple Retina Display, Quad HD, or WQHD).

The PAMSys motion sensor is ready to use right away, just turn it on, put it on, and collect data.

PAMSys is an acceleration based system. The PAMSys motion sensor records 3-axis acceleration and can optionally be ordered with a 3-lead ECG option.

Under normal operating conditions the PAMSys motion sensor can record data continuously, without battery recharge, for 200 hours (upgradeable to 340 hours).

The PAMSys motion sensor is not waterproof though it is designed to withstand typical moisture and sweat encountered during everyday usage.

The patented PAMSys technology uses advanced signal processing algorithms and novel biomechanical models of human motion to identify the complete physical activity map of the user from data measured by a single 3-axis accelerometer.

PAMSys measures posture, gait, and postural transitions. The system provides a continuous report of whether the wearer was sitting, standing, lying down, or walking. During each episode of walking the system measures cadence, number of steps, and step time variability. Every time the wearer goes from standing to sitting (or vice versa) the system measures the duration and time of occurrence of the postural transition. Increases in postural transition duration or in the number of attempts before a successful transition is achieved are important indicators of declining physical well being and increasing instability.

Yes, PAMWare  estimates the Metabolic Equivalent of Task (MET) based on measured physical activity.

Each purchase of PAMSys software (PAMWare) comes with one USB data link. Simply place the motion sensor on the USB stand and run the PAMWare software to transfer the data from the motion sensor to your computer. Additional USB data links can be purchased separately.

Yes, PAMWare will output processed data and graphs to Excel, as well as output raw data to a .csv or a Matlab readable binary file.

All BioSensics products come with a 30-day full satisfaction money-back guarantee. If you are not satisfied with PAMSys or PAMWare for any reason you can return it for a full refund (not including shipping costs). In addition, each PAMSys motion sensor carries a 1-year warranty against defects in materials and workmanship under normal use. PAMWare comes with one year of technical support and free software upgrades.

The PAMSys sensor is worn on the front of the torso. It can be worn using a chest strap (included with each motion sensor purchase) or using PAMShirt (sold separately). PAMShirt is a custom made t-shirt designed to hold the PAMSys motion sensor and is available in a range of sizes.

PAMSys is a single motion sensor worn on the torso that is used to measure physical activity. The PAMSys-X option allows for additional sensors to be added to the system. These sensors measure tri-axial acceleration and are time-synchronized with the main PAMSys sensor on the torso. The PAMSys-ECG option adds a 3-lead ECG to PAMSys enabling concurrent monitoring of physical and cardiac activity.
