Patent number: 11042129Abstract: Systems and methods for a redundant wireless safety system that provides a second level of safety protocol when a worker is exposed to a more dangerous work environment. In an embodiment, such a machine may be configured to perform a specific manufacturing function wherein the machine may include first and second transceivers for maintaining enabling signals for functionality of the machine. The system may further include a base station (e.g., remote control) configured to operate in conjunction with the machine that in turn includes third and fourth transceivers also configured to maintain enabling signals for machine functionality. Machine functionality may be interrupted by an interrupt switch disposed in the machine. That is, the interrupt switch may be configured to enable functionality of the machine if and only if the first transceiver maintains periodic communication with the third transceiver and if the second transceiver maintains periodic communication with the fourth transceiver.Type: GrantFiled: June 5, 2019Date of Patent: June 22, 2021Assignee: Control Dynamics, Inc.Inventor: Eric M.

Patent number: 10667583Abstract: A control docking station system for controlling locking engagement between a first female member and a male member that together form a locking mechanism. The first female member is connected to a safety device. The male member can be locked to and released from the first female member. The system includes a controller configured to sense an unsafe interlock signal. A second female member is operably connected to the controller's housing. Each female member includes a receiver base and a pair of pivoting locking tabs that is engageable with a key-like projection on the male member. The male member may be unlocked from the first female member when the controller senses an interruption to the unsafe interlock signal or if the unsafe interlock signal is overridden. The male member may be docked in the second female member during safe circumstances and/or the safety device is unused.Type: GrantFiled: December 6, 2018Date of Patent: June 2, 2020Assignee: Control Dynamics, Inc.Inventor: Eric M.

Patent number: 10568393Abstract: A system and method for a locking mechanism that includes an ability to indicate proper engagement via a signal cable coupled through a harness. The locking mechanism may include electronic components including three magnetic actuators and corresponding electronic switches that signal change of state. Locking tabs and a leading edge of the insert respectively include the three magnetic actuators. The electronic switches, which may be magnetically activated reed switches, signal status change to an external controller and, optionally, an external computer. Further, status signals and power signals may be routed through a steel cable or woven nylon harness that coupled the locking mechanism to a local anchor point. Change of status notification may be important on critical safety worksites where lack of mechanical and electronic connection can be life threatening.Type: GrantFiled: May 2, 2017Date of Patent: February 25, 2020Assignee: Control Dynamics, Inc.Inventor: Eric Moran
