In operation, a user 62 or service technician may transport the service unit 32 along hallways 64, which may be located on a plurality of floors 66 of the building 40. As depicted, a first floor 66a includes a first suite 42a, a second suite 42b, a third suite 42c, and a fourth suite 42d. Each of the suites 42 includes a corresponding support apparatus 10 or, more generally, a remote device 60 configured to communicate with the service unit 32. Accordingly, the suites 42 on the first floor 66a include a first support apparatus 10a, a second support apparatus 10b, a third support apparatus 10c, and a fourth support apparatus 10d. Additionally, a second-floor 66b of the building includes a fifth suite 42e and a sixth suite 42f that include a fifth support apparatus 10e and a sixth support apparatus 10f, respectively. Accordingly, without further identification available to the user 62, it may be challenging to distinguish the remote devices 60 (e.g., the patient support apparatuses 10) such that a specific device (e.g., the second support apparatus 10b) can be verified for maintenance or service.
Once activated in a service mode, the service unit 32 may be configured to detect a wireless broadcast signal from each of the remote devices 60 within a detection range 70 via the wireless communication interface 30. As depicted, each of the first support apparatus 10a, the second support apparatus 10b, the third support apparatus 10c, and the sixth support apparatus 10f are within the detection range 70 of the service unit 32. Accordingly, an application operating on the service unit 32 may present each of the remote devices 60 within the detection range 70. Additionally, once each of the support apparatuses 10a, 10b, 10c, and 10f is within the detection range 70, the corresponding controllers 20 may detect that the service unit 32 is nearby based on a wireless signal transmitted over the wireless communication interface 30. In response to identifying the wireless broadcast signal from the service unit 32, each of the controllers 20 of the support apparatuses 10 located within the detection range 70 may control the indicator device 34 or visual indicator to activate a first indicator 34a. In this way, the user 62 may be able to visually identify each of the patient support apparatuses within the detection range 70 by simply viewing the first indicator 34a through a window 72.
The indicator device 34 may be embodied by a variety of devices, displays, emitters, light arrays, etc. For example, the indicator device 34 may correspond to a display screen (e.g. a liquid crystal display [LCD]) configured to illuminate in a first color or symbol to provide the first indicator 34a and a second color or symbol to provide for the second indicator 34b. Additionally, the indicator device 34 may include a third indicator 34c that may be illuminated as a third color or symbol on the display screen. Accordingly, a contiguous display screen or multi-color emitter may provide for the functionality of the first indicator 34a and the second indicator 34b. As shown in
In some examples, the indicator device 34 may include a projection device configured to project light from each of the indicators 34a, 34b, 34c onto a floor or wall located near the support apparatus 10 in the patient suite 42. The projection device may include an articulating emitter or projector configured to adjust a direction of the light output from the indicators 34a, 34b, 34c. In operation, light from the projection device may pass from the indicators 34a, 34b, 34c through cutouts and project images communicating the status of the support apparatus 10 identifying a proximity within the detection range 70 via the first indicator 34a and a connection status with the service unit 32 via the second indicator 34b. Additional examples of lights and indicators that may be used for the indicator device 34 or visual indicator are discussed in detail in U.S. Pat. No. 9,655,798 titled, “MULTI-ALERT LIGHTS FOR HOSPITAL BED,” the disclosure of which is incorporated herein by reference. Though described as the first indicator 34a, the second indicator 34b, and the third indicator 34c in reference to specific functions or operational identifications, the indicator device 34 may be configured to output one or more indications to suit a variety of operations. Accordingly, the specific references to the first indicator 34a, the second indicator 34b, and the third indicator 34c are for clarity and the number of indicators and associated functions may vary without departing from the spirit of the invention.
As further discussed in reference to
Once communication is established between the service unit 32 and the support apparatus 10 (e.g., the second support apparatus 10b), the controller 20 may activate the third indicator 34c to identify a confirmation of one or more operations controlled or communicated to the controller 20. For example, in response to a completion of an activity or process of the support apparatus 10, the controller 20 may activate the third indicator 34c to output a visual indication that the activity is complete. For example, the controller 20 may activate the third indicator 34c in response to the completion of an activated feature, a control instruction, a configuration application, a software or firmware update, or various other processes. Such activity may be controlled by the controller 20 in response to a communication from the service unit 32 communicated via the communication interface 30. Accordingly, the indication device 34 may be configured to output visual indications identifying a variety of activities related to the operation of the support apparatus 10 including the operation of various devices and/or peripherals (e.g., remote devices 60) in communication with the support apparatus 10.

In addition to the address list 82, the application interface 80 may further demonstrate an inventory list 84, a service list 86, a signal strength meter 88, and a connection selection input 90. In addition to the addresses of each of the support apparatuses 10 within the detection range 70, the address list 82 may further provide a signal strength identification 92 indicting which of the support apparatuses 10 is closest in proximity based on overall signal strength. Accordingly, the addresses in the address list 82 may be organized based on the greatest signal strength and generally the corresponding closest proximity of each of the support apparatuses 10, which may aid the user 62 in distinguishing the support apparatuses 10 from one another. The application interface 80 may further include the inventory list 84, which may identify each of the patient support apparatuses 10 or, more generally, remote devices that have been reported in the inventory of the hospital building 40. While the inventory list 84 may be informative, one or more of the remote devices 60 in the inventory list 84 may not be scheduled for service by the user 62. Accordingly, the application interface 80 may further include the service list 86, which may identify a subset of the remote devices 60 or support apparatuses 10 scheduled for service during the visit by the user 62. Accordingly, the inventory list 84 and the service list 86 may be utilized by the user 62 to organize and track the support apparatuses 10 and, more generally, various types of remote devices 60 that may be controlled, updated, and/or serviced by the service unit 32.
Once one of the detected address is selected, as indicated by the connection selection input 90, the application interface 80 of the service unit 32 may display a directional signal strength indicator 94 identifying a proportional direction of the communication signal communicated from a selected address 96. The direction and strength of the signal of the selected address 96 may be identified by the service unit 32 based on an angle of arrival and an angle of departure of communication signals transmitted to and from the controller 20 of the patient support apparatus 10. In this way, the application interface 80 of the service unit 32 may provide an identification of a direction of the patient support apparatus 10 corresponding to the selected address 96, such that the user 62 may easily traverse the hallway 64 and identify the location of the patient support apparatus 10 to which the selected address 96 is assigned. As previously discussed, once the controller 20 of the patient support apparatus 10 is connected to the service unit 32, the controller 20 may activate the second indicator 34b of the indicator device 34, such that the user 62 may verify that the connected device is the device believed to be in communication with the service unit 32. In this way, the service unit 32 may guide the user 62 to the support apparatus 10 to which the selected address 96 is assigned and communicate with the controller 20 of the corresponding patient support apparatus 10 to activate the second indicator 34b, thereby verifying that the service unit 32 is in communication with the desired support apparatus 10.
As previously discussed, in the event an activity or process of the support apparatus 10 is completed, the controller 20 may activate the third indicator 34c to output a visual indication that the activity is complete. For example, once the communication between the controller 20 and the service unit 32 is established, the service unit 32 may be utilized to communicate one or more instructions or request indications of the status of the operation of the support apparatus 10 or a connected device. In response to the completion of an activated feature, a control instruction, a configuration, a software or firmware update, or various other processes; the controller 20 may activate the third indicator 34c. Similarly, the controller 20 may illuminate the third indicator 34c or a fourth indicator (not shown) to indicate that the instruction or activity was not successfully completed. In some examples, the third indicator 34c may be activated by the controller 20 to illuminate in a first color indicating a confirmation of an activity or operation of the support apparatus 10. Additionally, the controller may activate the third indicator 34c in a second color indicating a failure of an activity or operation of the support apparatus 10. Accordingly, the indication device 34 may be configured to output visual indications identifying a variety of activities related to the operation of the support apparatus 10 including the operation of various devices and/or peripherals (e.g., remote devices 60) in communication with the support apparatus 10.

In step 164, the service unit 32 may identify whether or not the authentication from step 162 is successful. If the authentication is not successful, the method 150 may continue by incrementing a lockout counter and potentially locking remote access to the controller 20 of the remote device 60 if the counter exceeds a counter limit for multiple unsuccessful authentication attempts (166). If the authentication in step 164 is successful, the method 150 may continue by displaying the configuration menu 122, which may include an identification of a serial number of the remote device 60 in communication with the service unit 32 (168). Additionally, once the communication is established, the controller 20 of the remote device 60 (e.g., the patient support apparatus 10) may control the indicator device 34 to activate the second indicator 34b (170). In this way, the controller 20 of the remote device 60 may control the indicator device 34 to visually distinguish the remote device 60 connected to the service unit 32 from the remaining remote devices 60 that may be within the detection range 70. The method 150 may continue to step 172 where the service unit 32 monitors for the disconnect input 136 or an inactivity timeout. Upon receipt of the disconnect input 136 or as a result of the inactivity timeout on the service unit 32, the method 150 may continue to step 174 and end the remote access routine disconnecting the connection between the service unit 32 and the remote device 60.
