Abstract: An intravenous (IV) medication filter device can include a housing having a medication inlet, a medication outlet, and a gas vent. The filter device can include a hydrophobic gas filter inside the housing between the inlet and the gas vent and between the gas vent and the outlet. The hydrophobic gas filter can prevent medication received into the housing via the inlet from existing the housing via the gas vent. The hydrophobic gas filter can permit gas in the housing to exit the housing through the hydrophobic gas filter via the gas vent. The vent hole can have a shape that prevents sterilizing radiation directed at the gas vent from reaching the hydrophobic gas filter. Optionally, a porous plug may be inserted into the gas vent and/or a radiation shroud may be positioned over the gas vent to protect the gas vent from being damaged by the sterilizing radiation.

Abstract: Described herein is a firearm magazine release lock that permanently fixes a magazine to a firearm. This device requires disassembly of the firearm action and disengagement of this device with a special tool prior to release of the magazine. The device comprises a retractable detent extending from a magazine catch that prevents simple removal of a magazine. This device requires disassembly of the firearm action and disengagement of this device with a special tool prior to release of the magazine. In some embodiments the device couples to a security bolt to prevent removal of the device from the firearm.

Abstract: A method and apparatus for controlling the process used in the heat treatment of glass measures the quality of the glass following the heat treatment process. Inputs to the control system for the heat treatment process derive from the automated inspection of glass following heat treatment. Outputs from the control system for the heat treatment process may adjust one or more parameters in the heat treatment process including a furnace or heating setting, a transport setting, and a quench or cooling setting.

Abstract: A primary device for a synchronous event system. In one construction, the primary device includes a solar panel operable to convert light into electricity; a receiver operable to receive a global positioning system time signal; a processor coupled to the receiver and operable to process the global positioning system time signal to produce a processed time component; a internal clock coupled to the processor and operable to store the processed time component and to increment relative to the processed time component thereafter to produce an internal time; and a transmitter coupled to the processor and operable to transmit the internal time to a secondary device for wireless reception by the secondary device and synchronization of the secondary device relative to the primary device.
