How to change patient field names e.g. zip code to postcode
All the patient field names e.g. Family name, Post Code etc can be changed to any user defined string. Go to the Configure System menu and select the PROGRAM then DATABASE modules. Search for \"Subject Field Names\" and then change the field name required.
What is the amplifier gain of the Espion acquisition system
The amplifiers have fixed gain, the actual value is not very interesting (input range is +/-0.5V with 16 bit resolution and 8 bit DC offset control) suffice to say that 1 ADC bit is approx. 1uV (without the 10kHz oversampling). The amplifier accepts input voltages +/-32mV chosen from the entire DC 1V range. The acquisition system actually oversamples at 10kHz and then averages 10 values to produce a sample rate of 1kHz. This is the equivalent of adding 2-3 bits of resolution. These values are summed together to form a 19bit sum, but because the software is only 16 bits you have to select either the top 16 bits or the bottom 16 bits. This is chosen by the gain setting. In V2 of the software there is an option on the amplifier menu (under channels in the protocol) to change the gain from 1X to 10X. This isn\'t really gain control but resolution control. A setting of 10X will produce signals where the sum is taken as the bottom (LSB) 16 bits which produces better resolution (100nV) but restricts the input to +/-3mV i.e. a loss of range. A setting of 1X uses the top 16 bits of the 19bit sum and keeps the range +/-30mV but loses resolution (1uV). The signal will look pixellated at high screen scaling. For most tests, this should be set to 10X. The only time you would want to change it to 1X is if you are recording a long sweep of fairly large signal amplitude and expect a DC drift of greater than 3mV. Not the normal case. V3 of the software no longer has this restriction as it uses 32bit sums and therefore you get the resolution and the range.
My database connection process is very slow
The Interbase database server can run very slowly on multi-processor systems.
Use a tool called IBAffinity from Karsten Strobel to tie the IBServer process to one processor. Available at: www.ait-augsburg.de.
It needs to be run every time the Interbase server restarts.
Run from the Command prompt. To query the current affinity mask.
C:\\> IB_AFFINITY -Q
Current affinity mask: System=3, IBServer=3
This will show the how many processors are installed.
This means you have two system processors installed (3 dec = 11 bin) and IBServer is
allowed to utilize both processors.
To change the affinity mask forcing the IBServer to run on one processor.
C:\\> IB_AFFINITY -A1
Affinity mask set to 1.
How do I install and program the ColorDome Desktop Ganzfeld
There is an application note specifically written to answer this topic. Download desktop Installation.pdf [1.1MB]. Also, several ColorDome protocols can be found on this web-site.
What are the filter characteristics used by the Espion
In Espion V2 software, the filters were FIR digital 256 tap, time invariance, equi-ripple designs, created in MATLAB. They don\'t equate directly to standard analogue filters. In Espion V3 software, the filters are IIR digital, 2 pole Bessel (constant group delay through passband) using a bilinear transformation and corrected for aliasing. Roll-off is 12dB/octave and about -5dB at the cutoff frequency. Ripple as standard Bessel (none to speak of). These are created using a program called Filter Solutions from Nuhertz Technologies LLC.
Can I add my own filters
Yes, but you will need a filter design package and we recommend Filter Solutions from Nuhertz Technologies LLC. For technical information about installing filter coefficients, contact Diagnosys directly.
When is post acquisition filtering going to be available
The Espion software V4 will contain post acquisition filtering including FFTs and should be available soon. This will be a free update to all customers and may be downloaded from this web-site when it is released.
Selecting patients by date examined
New in V3 build 20 (patch 20) onwards is the ability to select or filter the patients in the database to show all the patients on whom you performed tests on any given day or range of days. To do this, the patient category filter has become a category/date filter. If you enter a valid date into this field, then the program assumes you are filtering by date otherwise it assumes by category. Dates should be in the form dd/mm/yyyy for non US countries and mm-dd-yyyy for the USA (two digit years are allowed). Which format is applicable is set in the configure system menu. Look for \"Country Type\" parameter under \"PROGRAM\" and then \"GLOBAL\" sections. For a range of dates (both dates being inclusive in the search) simply type two dates separated by a space e.g. 01/04/02 30/04/02 will produce all patients who were tested between 1st April 2002 and 30th April 2002 inclusive. The program also understands the words TODAY and YESTERDAY (case insensitive) which can be substituted for a date e.g. YESTERDAY TODAY would show all patients tested from yesterday until now.
Hiding Protocols
new in V3 build 20 (patch 20) onwards is the ability to hide protocols. often when designing a protocol, you create a best guess protocol and then record some data with it. The program then blocks your ability to modify the protocol whilst recorded data is stored in the database. This ensures that all data recorded with a particular protocol were recorded in a similar way - data integrity. Thus if you want to keep the data, but modify the protocol you must make a copy of the protocol and modify that. This leaves two protocols listed in the protocol section when you only want one. The solution is to hide the protocol using the new hide option. You can still see the data results listed under the patient that produced them. The hide option is located on the first page of the protocol parameters along with the stimulus generator and number of channels to record. You can re-show hidden protocols by pressing the \"Show Hidden\" button located at the bottom of the protocol list menu. A hidden protocol has a small black square drawn above and to the right of the protocol description to denote it is hidden.
How do I change the current result for more than channel at a time
If you have more than one result per channel, then one of the results is denoted as the \"Current Result\". This result is normally painted in a different color and most actions are performed upon it. You can change which result is the current on, by pressing the \"Next Result\" button in the tools menu which appears at the right hand side of the display, or selecting it directly from the list of results. This action normally only effects the \"Current Channel\". However, it is often advantageous to change the current result for all the channels simultaneously. This can be done, by pressing the \"Result and Trials\" button at the top right of the screen to produce the tools menu, then pressing the \"More...\" button from the tools menu and finally the \"All Channels\" button at the top of the tools menu.
My Espion console doesn\'t communicate on my network
This is one of the more common problems and may be caused by several different causes. all BOSER CPU Espion consoles (Celeron CPUs) contain a 10/100mb/s based LAN and all earlier INSIDE based CPU consoles contain a 10mb/s based LAN. The network hardware is permanently enabled on BOSER cpu cards, but enabled/disabled in the BIOS on INSIDE cpu cards. The first check one should make is that the console can communicate with any other PC i.e. the internal console wiring is working correctly. This requires connecting a PC (or laptop) directly into the PowerBloc using a crossover patch cable. To make matters simple, the network parameters on the console should be set up for TCP/IP with netbeui installed, no DNS, and set to obtain an IP address automatically. This gives the most likely chance of succeeding. If you manage to make this work, then you need to reconnect your network and install the network TCP/IP parameters. If you find you still can\'t communicate, then try turning off the 100mb/s mode and changing to half duplex mode. These parameters may be found in the network interface card settings.
I can\'t see the TFT screen through the Ruby red filter
If you are having trouble seeing the graphic result screen through the red filter, then try turning on the DIM screen mode. Press the \"Display\" button at the top left of the graphic screen and then the \"More...\" button in the display menu that appears. You should now see a \"Dim\" button which if pressed, will remove much of the screen color and make things more visible though the filter.
