| 20100127821 | Access Control - According to an aspect of the present invention, there is provided a method and apparatus for controlling access to a restricted area containing machinery. The method comprises receiving from a communications device a location identifier associated with said restricted area and a further identifier, verifying said location identifier and said further identifier, and controlling access to said restricted area based upon said verifying. Controlling access to said restricted area comprises providing a control signal to a controller associated with said restricted area. The controller is arranged to control said machinery in response to said control signal. | 05-27-2010 |

| 20110291775 | Portable Actuator Assembly - A portable actuator and safety switch assembly wherein the portable actuator includes a housing and an actuator for selectively engaging with a control mechanism of said safety switch. The actuator is at least one of partially located within the housing, forms a part of the housing, or is attached to the housing. The assembly includes a controller that controls a configuration of the actuator assembly, such that the actuator assembly can selectively and controllably attain a first configuration wherein the actuator is able to interact with the control mechanism of the safety switch and a second configuration wherein the actuator is unable to manipulate the control mechanism of said safety switch. | 12-01-2011 |
| 20110291776 | SAFETY SWITCH - A safety switch assembly having a number of fixed and movable contacts, a control mechanism that alters the conducting state of the contacts, and a magnetisable member that extends between alternate portions of the safety switch assembly. The safety switch assembly includes a magnetically operable electrical switch that is located in a body of the switch assembly and positioned proximate the magnetisable material such that changes in the magnetic condition of the magnetisable material alter the conducting state of the magnetically operable electrical switch. | 12-01-2011 |
