Patent CA-3126253-A1 (CA)
Inventor: ATATEKIN IRFAN SAIM
IPC: F24F9/00
Filed: 2021-07-29
Abstract: A novel and versatile vertical ventilation diffuser system to reduce transmission of airborne particles provides an harmful airborne particle nearly free indoor environment for one or multiple person to breathe, and to isolate and protect the personal space of a person by means of reducing the horizontal flow of air inside an enclosed space and transporting any possible harmful airborne particles, such as viruses, by means of a top down air flow. Thereby, a continuously clean environment is maintained by generating an air curtain around each person by means of a vertical ventilation diffuser system, which may be custom designed and sized for multiple types of suspended ceilings, or in standard sizes, with particular application in office, school, restaurant or concert hall settings. The versatile vertical ventilation diffuser system may further be implemented in a matrix configuration to promote the use of multiple users in a single indoor space.

IPC: G06N20/00
Filed: 2018-05-02
Abstract: Systems and methods for using a mathematical model based on historical information to automatically schedule and monitor work flows are disclosed. Prediction methods that use some variables to predict unknown or future values of other variables may assist in reducing manual intervention when addressing incident reports or other task-based work items.  For example, work items that are expected to conform to a supervised model built from historical customer information. Given a collection of records in a training set, each record contains a set of attributes with one of the attributes being the class. If a model can be found for the class attribute as a function of the values of the other attributes, then previously unseen records may be assigned a class as accurately as possible based on the model. A test data set is used to determine model accuracy prior to allowing general use of the model.
