DETAILED DESCRIPTION
For purposes of the description hereinafter, spatial orientation terms, as used, shall relate to the referenced embodiment as it is oriented in the accompanying drawing figures or otherwise described in the following detailed description. However, it is to be understood that the embodiments described hereinafter may assume many alternative variations and configurations. It is also to be understood that the specific components, devices, and features illustrated in the accompanying drawing figures and described herein are simply exemplary and should not be considered as limiting.
Referring to FIGS. 1-10, a door assembly 10 for a transit vehicle 12 according to one aspect of the present disclosure is shown. The door assembly 10 includes a door frame 14 and a vehicle door display system 16. The door frame 14 defines an opening 18 configured to receive a glass panel. The door assembly 10 may be opened and closed using any suitable actuation mechanism (not shown), which may be automatic and/or manually-controlled by an operator. The transit vehicle 12 may be a bus, railway passenger vehicle, or any other suitable vehicle. The vehicle door display system 16 includes a display 20 configured to display information 22 to a vehicle passenger 24 and a sensor 26 configured to detect the vehicle passenger 24 when the vehicle passenger 24 is in a predetermined area 28. The display 20 is configured to change the information 22 when the sensor 26 detects the passenger in the predetermined area 28. The display 20 may be manufactured with at least one of the following technologies: thin-film transistor (TFT) liquid-crystal, organic light-emitting diode (OLED), or electronic ink (eINK), although other suitable display technologies may also be utilized. The sensor 26 may include one or more of the following: a passive infrared (PIR) sensor, a microwave sensor, an ultrasonic sensor, a vibration sensor, a pressure/contact sensor, a camera-based sensor, or any other suitable sensor configured to detect the position of one or more vehicle passengers. The change in the information 22 displayed on the display 20 when the sensor 26 detects the passenger 24 in the predetermined area 28 may be to display a door opening indicator to notify the passenger of the opening door, to activate advertisements, to activate a safety alert instructing the passengers to exit the specified area due to door opening or restrictions while the vehicle is moving, etc.
As shown in FIG. 10, the vehicle door display system 16 also includes at least one processor 30, or any other like computing device, for controlling the vehicle door display system 16, and a communications module 32 configured to receive information from a user, a network, or other suitable source. The communications module 32 is configured to display real-time information on the display 20, although the vehicle door display system 16 may also include preloaded messages or content stored on a storage or memory device. The communications module 32 may include one or more of an input port, such as a USB port, a cellular mobile communication device, a wireless local area networking device, and any other suitable communications device for receiving and transmitting information.
Referring to FIGS. 6 and 8, in one aspect of the present disclosure, the door assembly 10 includes a first glass panel 40 and a second glass panel 42 each secured to the door frame 14. The display 20 of the vehicle door display system 16 is positioned between the first and second glass panels 40, 42. As shown in FIG. 6, the display 20 may only occupy a portion of a space 44 between the first and second glass panels 40, 42. As shown in FIG. 8, the display 20 may entirely occupy the space 44 between the first and second glass panels 40, 42.
Referring to FIG. 7, in one aspect of the present disclosure, the door assembly 10 includes a single glass panel 46 secured to the door frame 14 with the display 20 secured to the glass panel 46.
Referring to FIG. 9, in one aspect of the present disclosure, the display 20 of the door assembly 10 is transparent and received within the opening 18 of the door frame 14 and secured to the door frame 14. The display 20 being transparent or partially transparent is configured to allow the passenger 24 to view the information on the display 20 while still being able to at least partially view objects on the opposite side of the display 20. The display 20 may be configured to impose a limit on the visibility or transparency, which is pre-programmed or selected by the passenger 24 or operator.
The information 22 displayed on the display 20 of the vehicle door display system 16 may be one or more of a vehicle state, a door status, local attractions, route information, safety alerts, and advertisements, although other suitable information may also be displayed. The door status may include a closed indication, an authorized indication, an open request indication, an opening indication, and an open indication, although other suitable door status indicators may be utilized. Referring to FIG. 4, the route information may include a system map 52 with the current vehicle location or other suitable information. Referring to FIG. 5, the information displayed on the display 20 may be based on the location of the transit vehicle 12, the position of other transit vehicles 54 for possible transfers, the location of the transit vehicle relative to a transit stop 56 or bus depot 58, etc.
Referring to FIGS. 1-3, the vehicle door display system 16 may include a user control 60 configured to allow the passenger 24 to select the information 22 on the display 20. The user control 60 may include one or more of the following: a touch screen, an external keypad, a trackpad, a smart phone 64, or any other suitable device or arrangement. The user control 60 may be a camera-based facial expression recognition system or camera-based gesture recognition system, which may be integral with the sensor 26 or formed separately from the sensor 26. The user control 60 may include capacitive sensors configured to recognize touch or gestures. The user control 60 may be configured to be automatically disabled based on predetermined events. For example, the user control 60 may be disabled as needed for safety purposes with alerts regarding the disabled user control or restricted actions being provided on the display. The predetermined events may be an upcoming transit stop, a vehicle emergency, police emergency, etc. The user control 60 and display 20 may be configured to allow external content such as advertising or entertainment to be displayed. The content may be responsive to the sensor inputs and user controls previously detailed such as to display locally relevant content, to browse advertisements, to control entertainment channels, to provide interactive entertainment and ads, or other purposes.
While embodiments of a door assembly were provided in the foregoing description, those skilled in the art may make modifications and alterations to these embodiments without departing from the scope and spirit of the invention. Accordingly, the foregoing description is intended to be illustrative rather than restrictive.
