Abstract: Techniques for controlling a process to prevent injury are presented. The techniques include obtaining a location estimation of a mobile transmitter affixed to an object, where the location estimation is relative to a location of a fixed receiver, and where the obtaining the location estimation includes sending an ultra wideband communication from the mobile transmitter to the fixed receiver and acquiring the ultra wideband communication by a phased antenna array of the fixed receiver; assessing, based on the location estimation, that the mobile transmitter is within an impermissible location; determining that the location estimation is sufficiently accurate based on a distance between the location estimation and the fixed receiver; and interrupting the process upon both assessing that the mobile transmitter is within an impermissible location and determining that the location estimation is sufficiently accurate.

Abstract: A communication receiver (100) includes a controller (206) providing control of at least first and second receiver operating states in response to corresponding first and second operations of at least one control (108, 110 or 112) by a user. A memory (216) stores a first control function table (308) defining an order by which a set of predetermined control functions is executed to control the first and second receiver operating states. A reconfiguration circuit (218), coupled to the memory (216) and to the at least one control (108, 110 or 112), enables the user to manually reconfigure the order by which a portion of the set of predetermined control functions is executed to control one or more different receiver operating states. The order by which the portion of the set of predetermined control functions is executed is stored within a second control function table (304) in the memory (216), and the controller (206) is responsive to the second control function table when stored.
