Abstract
A system for operating a communication device in a healthcare facility includes a locating system configured to determine locations of assets in the healthcare facility. The system also includes a communication device having a microphone array configured to detect sound signals within a detection lobe defined by an angle and an accelerometer to determine an orientation of the device.
Claims20
A method of adjusting a communication device for use in a healthcare facility based on a location of assets in the healthcare facility, the method comprising:
- detecting sound signals within a detection lobe of a microphone array of the communication device, wherein the detection lobe is defined by an angle,
- receiving a message from a locating system related to a position of at least one asset in the healthcare facility, and
- adjusting a magnitude of the angle of the detection lobe with a controller in response to the message received from a locating system,
- wherein the controller adjusts the magnitude of the angle of the detection lobe based on a proximity of the communication device to the at least one asset in the healthcare facility.
A method of adjusting a communication device for use in a healthcare facility, the method comprising:
- detecting a plurality of sound signals within a detection lobe of a microphone array of the communication device, wherein the detection lobe is defined by an angle and the microphone array includes a plurality of microphones,
- receiving at each microphone of the plurality of microphones at least one of the plurality of sound signals,
- determining a time of arrival of each of the plurality of sound signals at the respective microphone of the plurality of microphones,
- inferring a location of a source of each sound signal of the plurality of sound signals based on the time of arrival of each of the plurality of sound signals, and
- adjusting a magnitude of the angle of the detection lobe by only processing the sound signals in directions of interest.
A method of adjusting a communication device for use in a healthcare facility, the method comprising:
- detecting sound signals within a detection lobe of a microphone array of the communication device,
- determining an orientation of the communication device with an accelerometer and adjusting a direction of the detection lobe based on input from the accelerometer.
