Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

Abstract: A remote speaker microphone having a directional microphone, a speaker, and a housing. The housing has a first portion sized to contain the speaker and a second portion sized to contain the directional microphone. The second portion defines a front port positioned adjacent the front surface of the directional microphone and a rear port positioned adjacent the rear surface of the directional microphone. The housing is configured to minimize the distance that sound waves travel within the housing before impacting on the sound receiving surfaces of the microphone.
