These blog articles explore the potential of FlowCloud by offering several real-world examples, from home control systems or healthcare to fully-fledged music subscription services.

Electronic healthcare systems are gaining in popularity, not just within the home environment where remote monitoring can reduce the necessity for a patient to regularly visit their doctor, but also for patient care within hospitals and emergency rooms. For these types of application high integrity, security and privacy of data are primary considerations. FlowCloud makes it easy.

Electronic healthcare systems need to be secure and reliable

In this example, the device itself takes the form of a medical patch worn by the patient which provides live monitoring of vital signs including respiration, heartbeat and body temperature. Each patch has a unique identifier which is used to enable security of the service by creating keys for encryption of data; the identifier is also assigned to the patient healthcare records, in effect creating a secure and trusted relationship between the physical world and digital domains – in this case between the patient and the data being generated by the patch.

FlowCloud - e-health patchThese are the Toumaz SensiumVitals® systems for wireless monitoring of patient vital signs in hospitals

FlowCloud enables multiple streams of data from the patch, itself having multiple sensors, to be directly and securely associated with each patient. It delivers live monitoring of all the vital signs through a PC, tablet or web-based application; this can be achieved within the hospital environment or remotely over the Internet via encrypted connections. Thresholds can be established on each of the data streams independently by healthcare professionals, with events or alarms triggered if values go above or below acceptable limits.

The status of the patch itself may also be tracked via FlowCloud, from initial use through to disposal: for example, confirming that there is sufficient battery life remaining or verifying that the patch is being worn by the patient and is within wireless range.

Aggregation of the data sets within FlowCloud enables the results to be collated from a potentially limitless number of patches, any or all of which can be presented to healthcare professionals via connected mobile apps or otherwise submitted to data analytics engines to derive and evaluate trends across a population of patients. All data sets are securely stored and managed at Imagination’s purpose-built FlowCloud data centre.

  1. SensiumVitals is not intended to replace ward staff duties.
    From the Senium Healthcare website, referring to a six month pilot involving 270 patients in a general med/surg ward st St John’s Health Centre, Santa Monica:-
    From a clinical perspective, the key benefit was the early detection of
    deterioration in the condition of a significant number (12%) of
    patients. This allowed earlier intervention and, for those affected,
    greatly improved patient outcomes than would have been expected under normal monitoring protocols.

  2. One of the basic but very important obs performed by ward staff is BP, which is in addition to pulse, O2 sats, resps and temp.
    Sensium cannot replace ward staff duties ( and therefore save time/money) until it can measure BP.
    There are many medical reasons why BP measurement is a mandatory ward observation which cannot be omitted. Until you address this issue Sensium is fairly pointless I’m afraid.

    • I think it is quite possible that you are the only one that thinks the sensium patch is meant to replace standard OBS, it isn’t.
      The saving isn’t from not using staff to do standard OBS, it is from identifying patient deterioration earlier, and thus intervening quicker,resulting in shorter hospital stays.
      This economic case was laid out in the US trial.

Vulkan synchronisation and graphics-compute-graphics hazards: Part I

How do you mix and match rasterisation and compute in a modern GPU? In modern rendering environments, there are a lot of cases where a compute workload is used during a frame. Compute is generic (non-fixed function) parallel programming on the GPU, commonly used for techniques that are either challenging, outright impossible, or simply inefficient to implement with the standard graphics pipeline (vertex/geometry/tessellation/raster/fragment).
