An improved method for assessing the geologic risk for hydrocarbon presence and hydrocarbon accumulation size is disclosed. In one configuration, seismic attributes are assigned to a horizontal axis and data quality to a vertical axis to form a matrix crossplot. Direct Hydrocarbon Indicators (DHI) derived from seismic data are used to qualify the presence and accumulation size. A quantitative method for scaling and calibrating the DHI matrix is illustrated that can be applied to existing petroleum basins and by analog to frontier areas.

A heating, ventilation, and/or air conditioning (HVAC) system includes an air handling unit configured to condition an outdoor air flow to generate a ventilation air flow. The HVAC system includes a terminal unit fluidly coupled to the air handling unit. The terminal unit includes a plenum configured to receive the ventilation air flow and a blower configured to draw a return air flow from a space serviced by the HVAC system across a heat exchanger of the terminal unit and into the plenum to condition the return air flow. The blower is configured to mix the ventilation air flow and the return air flow to generate a supply air flow. A displacement ventilation (DV) diffuser is configured to receive the supply air flow. The DV diffuser is configured to direct the supply air flow through a filter of the DV diffuser and into the space.

Removing a gun or other weapon from a holster may inevitably require police backup to secure officer safety. One example device may include a weapon securing holster and a wireless presence detection antenna which receives wireless proximity data from a weapon drawn from the holster. Other features may include a sensor which detects a presence of the weapon and a processor which processes sensor data generated by the at least one sensor and radio frequency signals identifying a proximity of the weapon to the wireless presence detection antenna.
