A method of change data captured is disclosed, in which modifications made to on-line transaction processing (OLTP) tables (e.g. inserts, updates, and deletes) are maintained in a database object, referred to as a change table. The change data in the change table is then made available to analysis applications in a controlled manner, such as in accordance with a publication-subscription model.

In a demand control ventilation (DCV) system, ID codes of tags worn by occupants are detected in each room by a tag detector and wirelessly communicated to a zonal occupancy compiler. The zonal occupancy count arrived at by the compiler is transmitted to a DCV microprocessor, which interfaces with the ventilation controller of the building's HVAC system and sets the zonal ventilation rate based on the occupancy count and applicable ASHRAE standards.

To control lighting and other utilities in buildings based upon occupancy, mountable sensors are used to detect low energy radio frequencies emitted from devices, or tags, worn or carried by occupants. In a demand control system, identification (ID) codes embedded in tags worn by occupants are detected in each room by a tag sensor and may wirelessly communicate to a zonal compiler that determines zonal occupancy. The zonal occupancy count is transmitted to an interface relay that immediately adjusts the intensity and rate of the specific utility. HVAC systems may also be tied into the system to have adjustments made to the intensity and rate of ventilation as done with the lighting in this system. This system has many advantages over current systems such as not being dependent upon movement of an occupant or following the heat signature of an occupant that both may lead to false readings and delay in adjusting the specific building utility to save energy and costs.

The present invention provides an object measuring apparatus capable of performing high-speed process and accurately counting the number of a plurality of objects even in the case where the plurality of objects pass a boundary line simultaneously. The object measuring apparatus extracts motion vectors at a plurality of times in each of a plurality of positions on a boundary line on the basis of a plurality of images. The object measuring apparatus obtains at least one integral value by integrating components perpendicular to the boundary line of the motion vectors. As the at least one integral value, for example, an integral value derived by integrating the perpendicular components of one of positive and negative signs is obtained. The object measuring apparatus calculates the number of moving objects (people and the like) passing the boundary line on the basis of the integral value.
