Great Lakes NeuroTechnologies Frequently Asked Questions
- Q. Can I operate more than one BioCapture/Kinesia/KinetiSense/Lab Course system at the same time?
A. You can operate multiple systems at the same time, with each system running on a separate PC. BioCapture software allows multiple BioCapture systems to be ran on one PC (requires multiple USB ports).
- Q. Can I have multiple User/Patient Units transmitter to a single USB Receiver?
A. No. Each User/Patient Unit is paired with a specific and exclusive USB Receiver. The two-letter Unit ID is intended to correct identify a User/Patient Unit and USB Receiver pair.
- Q. To what data formats can I export?
A. All GLNT software packages allow for export to popular ASCII data files formats, specifically common separated values (CSV) files. Lab Course (formerly CleveLabs) signal data is saved as a DATA file, which is also ASCII.
- Q. Is the sampling rate aggregate or the same for each channel?
A. The sampling rate is the same for each channel; the exception being the slow, fixed inputs in BioCapture, which are 1/10 of the programmable sampling rate.
- Q. What is the noise floor in BioCapture?
A. The noise floor is different for each input range. For the smallest input range, ± 750 µV, the noise floor is ± 1 µV. Contact GLNT support for additional noise floor information.
- Q. What are the input specifications for the DC Auxiliary input?
A. The DC Auxiliary input has an input range of ± 1.7 V and samples at the speed of the programmable sampling rate.
- Q. How do I set the gain in BioCapture?
A. You can select a predetermined input range in the Configuration Wizard, and the gain will be automatically adjusted based on the input range and signal type.
- Q. What are the export options in BioCapture?
A. You can export data into a comma-separated values (CSV) file. Export field options include duration, channels, data with specified gains and offsets applied and real and/or elapsed times. Remember: .CSV files do not allow for filtering.
- Q. I have an old BioRadio system. Will the current BioRadio SDK support it?
A. The current BioRadio SDK supports and has been tested with both new and legacy BioRadio 150 systems. This testing and support has involved both the USB Receiver (new) and Computer Unit (legacy). Each programming environment supported by the SDK has a specific function (i.e., CreateBioRadio in C++) to identify new and legacy systems. Please do refer to BioRadio SDK documentation for more information.
- Q. Why does the Command Module charge light not turn on when I connect it to my PC?
A. If left uncharged for an extended amount of time, the Command Module will not turn on immediately when connected and will require approximately 30 minutes to two hours of charging before and initial charge can be completed and a normal charge can begin. After an initial charge, the Command Module's charge light will turn on and will be detected by your PC. Please do allow the Command Module to fully charge (charge light will turn off) before use. If your PC is a laptop, please ensure that your power saving settings do not turn off power to connected devices. If your Command Module cannot be detected after 2 hours of being connected to your PC, please contact Great Lakes NeuroTechnologies for customer support.
- Q. How do you calculate joint angles?
A. Neither KinetiSense nor Kinesia software automatically calculate joint angles. See this guide for more information on joint angles. (Applies to KinetiSense as well)
- Q. What do I do when the Patient Unit flashes 5 -10 times and I receive a Patient Unit cannot be found error in Kinesia software?
A. If your Kinesia Patient Unit cannot connect remotely thorough Kinesia software and the green power/recording LED flashes repeatedly, the Patient Unit's memory is near full and needs to be cleared. Using the USB charge cable, simply connect your Patient Unit and download any unsaved study data and delete the study data from the Patient Unit's memory. If your Patient Unit cannot be detected when connected to your PC, please contact Great Lakes NeuroTechnologies for customer support.
We strive to deliver BioRadios with robust wireless data acquisition using the latest radio technology. However, as with any wireless system, there are specific guidelines to help minimize any interference or dropped data. Several techniques to minimize dropped packets with the BioRadio are listed below:
- Keep the User Unit several feet away from any PCs and other electronic equipment, such as TVs, radios, lights, kitchen appliances and stereo speakers. Devices such as these can interfere with the User Unit's RF link.
- Keep the User Unit and Computer Unit/USB Receiver at least 3 feet (9 m) apart.
- Adjust the latency time on the USB Serial port. Changing the latency to 1 millisecond prevents the Computer Unit/USB Receiver from overflowing with sent packets, which alleviates dropped packets. Details are here.
- Low batteries. If your User Unit starts flashing, the battery life is low and packet loss is almost inevitable; replace batteries with new ones. Keep in mind the User Unit's batteries last about 12 hours.
- If possible, Try to duplicate dropped packets on another PC. If the above tips don't resolve the problem, and dropped packets can't be duplicated on a second PC, then the issue may be PC hardware specifications that do not meet the BioCapture requirements or other software applications running on the PC which interfere with BioCapture.
- If there is the rare occasion of dropped packets, the BioRadio software pads the data so that time synchronization remains intact.
For current BioRadio and KinetiSense users (i.e., using BioCapture software 4.0 or later, or KinetiSense software 1.4 or later) please refer to the BioRadio and KinetiSense SDK pages for the latest SDKs.
To help accommodate software development of older BioRadio and KinetiSense systems, below is a list of previous SDKs with corresponding system hardware models and system software versions.
Legacy SDKs are available "as is", without warranty or guarantees of any kind, either expressed or implied.
