Abstract: A modular smoking device has a base module having a main body, a bottom, and an upper female connection end, an ice catcher module having a main body, an upper end, a lower male connection end, an interior chamber having a floor member having a number of notched openings with the notched openings for capturing ice placed in the interior chamber, and the lower male connection end for fitting within the upper female connection end of the base module, and a mouth cylinder module having a main body, an upper end, a lower male connection end, and an interior chamber, and the lower male connection end for fitting within the upper end of the ice catcher module.

Abstract: An electronic lock system including an access control device configured to provide system instructions, an interface module electrically coupled to the access control device and configured to transmit RF signals in response to system instructions received from the access control device, and a plurality of wireless electronic door locks each configured to wirelessly communicate with the interface module. Each of the wireless electronic door locks includes a controller and a wireless receiver operatively connected to the controller, the wireless receiver including a first antenna defined as a circuit board trace and a second antenna, spaced from the first antenna and defined as a circuit board trace. Each of the first antenna and the second antenna include one of a monopole antenna and a fractal antenna. The controller is configured to switch between the first antenna and the second antenna to receive a wireless signal having a greater signal strength.
