Abstract:
1. A touchless transmitter for controlling access to a location, comprising: a sensor configured to detect a presence of an object within a predetermined sensing range to control a structural barrier controlling access to a location; a sensor adjustment device configured to selectively increase and decrease the sensing range of the sensor in which the presence of the object is detected to control the structural barrier, the sensor adjustment device being adjustable to increase and decrease the predetermined sensing range by moving a portion of the sensor adjustment device; upon detecting the presence of the object within an adjusted sensing range of the sensor, an antenna configured to wirelessly transmit a signal to a receiver, the receiver configured to control access to the location through movement of the structural barrier, the signal being transmitted in order to control the structural barrier; and an indicator configured to provide an output from at least one of a visual indicator and an audible indicator, the visual indicator including a light, the output being provided upon detecting the presence of the object within the adjusted sensing range of the sensor at least when configured to control the structural barrier controlling access to the location, the output of the indicator further indicates a transmission of the signal to the receiver, and the indicator configured to deactivate the output only upon termination of the transmission of the detection signal to the receiver; a power supply providing power to the touchless transmitter, the output of the indicator indicating when the power supply is below a threshold.
