    New Upgrade of COP Almost Ready for Release
    BIT, Inc. is about ready to release another upgrade and version of COP_WIN and COPWORKS, Version 5.06. Existing customers will be sent a free upgrade copy within the next 3 or 4 weeks. The new COP version allows you more flexibility when using dZ/dt peaks and Electrode Distances on a EA by EA basis. Several new features and modifications have also been added.

    AIM with Flash Memory Not to be Released Until October
    The AIM-8F (or AIM-8-V3F) units and upgrades to AIM-8F's will not be available until late September or October, as it now stands. We are having some difficulties getting some of the custom materials in a timely fashion.

    A New, 'Smart' AIM Blood Pressure Sensor Developed
    We have just developed a new 'Smart' BP sensor arrangement for the AIM-8 devices (the AIM-BPSS) which eliminates the multiple triggering (multiple EA's) that occur with some of the newer oscillometric-type BP monitors like the 'Oscar' and the 'Space Lab' units. Extensive testing has revealed that these types of BP monitors can cycle the cuff pressure up and down over extreme pressure ranges up to 4 or 5 times in order to obtain one BP reading during difficult situations. This, in turn, causes the AIM-8 to take 4 or 5 readings (EA's) for the one BP measurement since the AIM has no way of knowing the BP monitor is throwing out readings and trying a new BP measurement again. This can fill up the AIM's memory with data well before it should, and also consumes unnecessary battery power in the AIM. The AIM-BPSS arrangement prevents this problem. To use this arrangement will require the New AIM-BPSS transducer ($250) and a new AIM code version (AIM-8P) to be loaded into existing AIM monitors.

    Price List Updated
    BIT's Price List has been updated to include the new AIM-BPSS.

    AIM-8-V3F Release Time Changed
    BIT announced on March 30, 2001 that the new AIM-8 monitor, the AIM-8-V3F, would be ready for release in August, 2001. The release date, however, was incorrect. The new AIM monitors are still undergoing testing and most likely will not be available until late this fall. We are very sorry for the misinformation.

    New AIM Monitor in Test Stages!
    BIT has just begun the test phase of its new AIM monitor, the AIM-8-F3. This monitor will function exactly as the AIM-8-V3, but it will be able to store more data (i.e. more Ensemble Averages), and, more importantly, it will have non-volatile, flash memory. With the new flash memory, the AIM-8-F3 will be able to store data and set-up information even if its power is cut. This means data won't be lost if a battery dies while a subject is under surveillance or while the computer is uploading data!

    Users with the AIM-8-V3 model will be able to upgrade to the new F3; however, this upgrade is not available for users of older AIM models.

    The new F3 model requires one additional computer board and one flash card (both produced by Persistor) in order to accommodate the new non-volatile, high capacity memory capabilities. The picture below shows the new computer board and flash card attached to the AIM module (board on far left).

    AIM's New Board

    With the additional memory boards, the AIM-8-F3 module is approximately " taller than the V3 module. The picture below shows the AIM-8-V3 module (left) and AIM-8-F3 module (right) side-by-side:

    AIM's New Board next to Old Board

    These additional memory boards used in the AIM-8-F3 require that a larger enclosure be used. The new AIM-8-F3 monitor is pictured below with the AIM module along side for comparison:
