Patent number: 8727392Abstract: Disclosed is a convertible motorized latch that may be configured in either of a slam latch or a dead bolt latch configuration, just by desired selection and replacement of a minimal number of components, and which may be used on new (oem) equipment or in retrofit applications. In either preferred configuration, an electric motor contained within the latch housing operates to open or unlock the latch. Latch closure may be provided by spring actuation in a slam configuration or by further motor operation in a dead bolt configuration. Either present configuration may make use of an electrical feedback switch for signaling latch retraction while the dead bolt configuration may also include a second electrical feedback switch for signaling latch extension. A gear train may be incorporated within the latch housing to provide reduced speed and increased torque from the electric motor.Type: GrantFiled: October 27, 2011Date of Patent: May 20, 2014Assignee: CompX International Inc.Inventors: Matthew R. Greiner, Kenneth A. Kaczmarz, Mitchell S. Mlynarczyk, Kenneth D. Graw, Francis H. Zimmerman

Patent number: 8199019Abstract: Disclosed are apparatus and methodology subject matters for temperature monitoring and controlled access to refrigerated medications. An electronically controlled lock is installed on a refrigerator used for storage of temperature sensitive medications. Lock access is given to individuals having differing levels of access authorization so that user level authorization holders may have access to stored medications. Supervisor level authorization holders may have access to stored medications and may also effect changes in lock settings including setting alarm levels. Alarm levels may be adjusted to monitor temperatures within the refrigerated storage area so that in the case that temperature fall outside preset limits, access to the stored medicines may be had only by those individuals having supervisory access authorization.Type: GrantFiled: November 14, 2008Date of Patent: June 12, 2012Assignee: CompX International Inc.Inventors: Kenneth A.
