DETAILED DESCRIPTION
FIG. 1 illustrates a system 100 configured for facilitating intercom communication for one or more quick-service restaurant drive-throughs, in accordance with one or more implementations. System 100 may be referred to as an intercom communication system, or as a communication system. In some implementations, system 100 may include an audio-order placement sub-system 101, one or more wires 104, a base station 103, an audio-order receipt sub-system 105, one or more networks 106, and/or other components and/or sub-systems. Users of system 100 may include customers (placing orders), staff members or crew (taking orders), managers and/or other stakeholders. In some implementations, orders may be placed by customers through audio-order placement sub-system 101, information pertaining to this order (e.g., based on the captured sound) may be transmitted through base station 103 (and/or networks 106 and/or one or more wireless connections 106a) to audio-order receipt sub-system 105. In some implementations, audio-order receipt sub-system 105 may be configured to perform automated order taking. In some implementations, audio-order receipt sub-system 105 may be configured to perform order taking remotely, at a remote order-processing center. In some implementations, audio-order receipt sub-system 105 may be configured to facilitate order taking locally at a quick-service restaurant, by staff members. In such cases, the pertinent information as transmitted by base station 103 may be received by staff members. Greetings, replies, and/or other sound by the staff members (which may be referred to as “restaurant sound”) may be captured by audio-order receipt sub-system 105. Information pertaining to the restaurant sound may be transmitted through base station 103 to audio-order placement sub-system 101, where the pertinent information is audible for the customers. To some extent, sound from customers placing orders and restaurant sound (and the information derived therefrom) may traverse opposite communication paths in system 100. In some implementations, sound from customers placing orders and restaurant sound (and the information derived therefrom) may be exchanged and/or otherwise transmitted at the same time, similar to any conversation.
Audio-order placement sub-system 101 may be positionally associated with one or both of a menu board and a speaker post (not depicted). In some implementations, one or both of the menu board and the speaker post may be part of a drive-through lane of a restaurant, e.g., a quick-service-restaurant. Audio-order placement sub-system 101 may include one or more of a microphone 10, a speaker 11, an encoder 12, a decoder 13, a digital-to-analog converter 14, an analog-to-digital converter 15, a transceiver 16, one or more processors 102, electronic storage 140, and/or other components. Components of audio-order placement sub-system 101 may be referred to as “order-placement” components. For example, encoder 12 may be referred to as order-placement encoder 12, and so forth.
Microphone 10 may be configured to capture sound. For example, in some implementations, microphone 10 may be configured to capture sound from a customer placing an order (and/or otherwise communicating with staff members) at or near one or both of a menu board and a speaker post. For example, in some implementations, microphone 10 may be included, embedded, and/or otherwise integrated into the speaker post of a drive-through lane of a quick-service restaurant. The captured sound may be referred to as “order sound”. In some implementations, microphone 10 may be configured to generate (analog or digital) information signals that represent the captured sound. For example, microphone 10 may be configured to generate order information signals that represent the order sound captured from the customer placing the order. In some implementations, the generated information signals may have an analog format. In some implementations, the generated information signals may have a digital format.
In some implementations, analog-to-digital converter 15 may be configured to receive analog information signals from microphone 10. In some implementations, analog-to-digital converter 15 may be configured to convert analog signals to digital signals. For example, analog-to-digital converter 15 may be configured to convert the received information signals to digital information signals that have a digital format. For example, analog-to-digital converter 15 may be configured to convert (analog) order information signals to digital order information signals. In some implementations, analog-to-digital converter 15 may be integrated into microphone 15, such that microphone 15 generates digital information signals that represent the captured sound.
Encoder 12 may be configured to encode digital information signals to form data packets. In some implementations, the data packets may conform to a network communication standard. For example, the data packets may conform to a network communication standard in accordance with IEEE 1901. For example, (order-placement) encoder 12 may be configured to encode digital order information signals (e.g., as generated by analog-to-digital converter 15) to form order data packets that conform to IEEE 1901. In some implementations, the formed data packets may conform to one or more other stream or packet-based standards.
Transceiver 16 may be configured to transmit and/or receive data packets. In some implementations, transceiver 16 may be configured to transmit and/or receive information via one or more communication links. In some implementations, (order-placement) transceiver 16 may be configured to transmit order data packets from audio-order placement sub-system 101 to base station 103. In some implementations, transceiver 16 may be configured to transmit data packets through pair of wires 104 (e.g., through a single pair of wires). In some implementations, transceiver 16 may be configured to transmit data packets through an Ethernet cable. In some implementations, (order-placement) transceiver 16 may be configured to receive (restaurant) data packets from base station 103, e.g., through the same single pair of wires. In some implementations, system 100 and/or transceiver 16 may be configured to use differential signaling over the single pair of wires. Decoder 13, digital-to-analog converter 14, and speaker 11 of audio-order placement sub-system 101 will be described below.
In some implementations, the only wires that are communicatively coupled between audio-order placement sub-system 101 and base station 103 may be a single pair of wires (pair of wires 104). In some implementations, single pair of wires 104 may be a twisted pair. In some implementations, single pair of wires 104 may be included in a balanced cable. In some implementations, communication via pair of wires 104 may use differential signaling. In some implementations, the wires that are communicatively coupled between audio-order placement sub-system 101 and base station 103 include more than two wires, but the transmission of (standardized) data packets may be performed such that only two of these wires are used to transmit data during the transmission of the data packets. For example, in some implementations, these wires may include a ground wire (which does not transmit data). For example, in some implementations, these wires may include one or more additional (pairs of) wires that are not used to transmit the data of the data packets during the transmission of the data packets as described in this disclosure.
In some implementations, at least one of analog-to-digital converter 15, digital-to-analog converter 14, order-placement encoder 12, order-placement decoder 13, speaker 11, and order-placement transceiver 16 is powered by power transmitted from base station 103 through the single pair of wires. In some implementations, power may be transmitted by base station 103 by applying a common voltage relative to ground to each wire in pair of wires 104 (and, e.g., using another wire as a ground wire). In some implementations, power may be transmitted by base station 103 by applying a differential voltage between the two wires in pair of wires 104 (e.g., using AC or DC, such as a DC voltage of nominally 48V). In some implementations, audio-order placement sub-system 101 may be configured to receive and/or otherwise extract power from pair of wires 104. In some implementations, at least two of analog-to-digital converter 15, digital-to-analog converter 14, order-placement encoder 12, order-placement decoder 13, speaker 11, and order-placement transceiver 16 are powered by power transmitted from base station 103 through pair of wires 104. In some implementations, at least three of analog-to-digital converter 15, digital-to-analog converter 14, order-placement encoder 12, order-placement decoder 13, speaker 11, and order-placement transceiver 16 are powered by power transmitted from base station 103 through pair of wires 104. In some implementations, audio-order placement sub-system 101 is powered by power transmitted from base station 103 through pair of wires 104. In some implementations, additional components not depicted in FIG. 1 (such as cameras, vehicle-detection blocks, (ultra-sonic) sensors, and/or other components commonly used in a drive-through lane) may be powered by power transmitted from base station 103 through pair of wires 104. Decoder 13 may be configured to decode data packets into digital signals. In some implementations, the data packets may have been transmitted by base station 103, and subsequently provided to audio-order placement sub-system 101. In some implementations, decoder 13 may be configured to decode restaurant data packets into digital restaurant signals (having a digital format). For example, in some implementations, restaurant data packets may conform to a network communication standard in accordance with IEEE 1901. For example, the restaurant data packets may conform to another streaming or packet-based standard. The digital restaurant signals may represent restaurant sound. For example, the digital restaurant signals may represent sound received and/or captured from staff members taking an order from a customer (and/or otherwise communicating with customers).
Digital-to-analog converter 14 may be configured to receive digital restaurant signals, e.g., from (order placement) decoder 13. Order-placement digital-to-analog converter 14 may be configured to convert digital signals to analog signals. For example, order-placement digital-to-analog converter 14 may be configured to convert the received digital restaurant signals to restaurant signals that have an analog format.
Speaker 11 may be configured to generate sound, e.g. restaurant sound, based on signals (e.g., restaurant signals). For example, speaker 11 may be configured to generate sound based on restaurant signals received from order-placement digital-to-analog converter 14. In some implementations, speaker 11 may be configured such that the generated sound is audible to one or more customers.

Referring to FIG. 1, external resources 141 may include sources of information outside of system 100, external entities participating with system 100, and/or other resources. In some implementations, external resources 141 may be communicatively coupled through one or more networks 106. In some implementations, external resources 141 may be communicatively coupled to base station 103. In some implementations, external resources 141 may include a remote order-processing center, which may perform (automated) order taking. In some implementations, some or all of the functionality attributed herein to external resources 141 may be provided by resources included in system 100.
In some implementations, system 100 may include more than one of audio-order receipt sub-system 105 or of its components. For example, some quick service restaurants may use or support two staff members taking orders. By way of non-limiting example, FIG. 2 illustrates an exemplary system 100a that is similar to system 100 in FIG. 1 (meaning that similarly named components have similar features and/or capabilities), but that includes two audio-order receipt subsystems, a first audio-order receipt subsystem 105a and a second audio-order receipt subsystem 105b. Audio-order receipt subsystem 105a may include a first headset 30a similar to headset 30 in FIG. 1 and a first transceiver 36a similar to transceiver 36 in FIG. 1, and be communicatively coupled to base station 103a via a wireless connection 106a.

Exemplary system 100b further includes a first audio-order receipt subsystem 105b and a second audio-order receipt subsystem 105c. Audio-order receipt subsystem 105b may include a first headset 30a similar to headset 30 in FIG. 1 and a first transceiver 36a similar to transceiver 36 in FIG. 1, and be communicatively coupled to base station 103a via a wireless connection 106b. Audio-order receipt subsystem 105c may include a second headset 30b similar to headset 30 in FIG. 1 and a second transceiver 36b similar to transceiver 36 in FIG. 1, and be communicatively coupled to base station 103a via a wireless connection 106c. 
By way of non-limiting example, FIG. 3B illustrates an exemplary system 100c that is similar to system 100 in FIG. 1, system 100a in FIG. 2, and system 100b in FIG. 3A (meaning that similarly named components have similar features and/or capabilities), but that includes two audio-order placement sub-systems, audio-order placement sub-system 101d and audio-order placement sub-system 101e (e.g., as part of a first drive-through lane and a second drive-through lane, respectively) connected to base station 103b via a pair of wires 104d and a pair of wires 104e, respectively. In some implementations, audio-order placement sub-system 101d and audio-order placement sub-system 101e may be self-contained units. For example, each of audio-order placement sub-system 101d and audio-order placement sub-system 101e may be integrated, embedded, and/or otherwise included in a separate speaker post. Exemplary system 100c further includes first audio-order receipt subsystem 105b and second audio-order receipt subsystem 105c, similar to previously described exemplary systems.
By way of non-limiting example, FIG. 3C illustrates an exemplary system 100d that is similar to system 100 in FIG. 1, system 100a in FIG. 2, system 100b in FIG. 3A, and system 100c in FIG. 3B (meaning that similarly named components have similar features and/or capabilities), and that includes two audio-order placement sub-systems, audio-order placement sub-system 101a and an audio-order placement sub-system 101b (e.g., as part of a first drive-through lane and a second drive-through lane, respectively) connected to base station 103b via a pair of wires 104d and a pair of wires 104e, respectively. In some implementations, audio-order placement sub-system 101a and audio-order placement sub-system 101b may be separated from their microphones and speakers, as depicted. Audio-order placement sub-system 101a may be communicatively coupled to speaker post 101x (e.g., as part of a first drive-through lane) via communicative coupling 106x. Audio-order placement sub-system 101b may be communicatively coupled to speaker post 101y (e.g., as part of a second drive-through lane) via communicative coupling 106y.

In some implementations where system 100 includes more than one of audio-order placement sub-system 101 or of its components, a first audio-order placement sub-system may be positionally associated with a first speaker post (and/or a first menu board), and a second audio-order placement sub-system may be positionally associated with a second speaker post (and/or a second menu board). In some implementations, the second audio-order placement sub-system may be communicatively coupled to base station 103 through a second pair of wires that is entirely independent and separate from pair of wires 104. For example, the second pair of wires may extend from base station 103 such that data packets transmitted from base station 103 to the second audio-order placement sub-system are not transmitted through (first) audio-order placement sub-system 101. For example, base station 103, the first audio-order placement sub-system, and the second audio-order placement sub-system may be arranged in a point-to-point topology. In some implementations, communication with the first audio-order placement sub-system may use different addresses than communication with the second audio-order placement sub-system.
In some implementations where system 100 includes more than one of audio-order placement sub-system 101 or of its components, a first audio-order placement sub-system may be positionally associated with a first speaker post (and/or a first menu board), and a second audio-order placement sub-system may be positionally associated with a second speaker post (and/or a second menu board). In some implementations, the second audio-order placement sub-system may be communicatively coupled to base station 103 through a second pair of wires that extends pair of wires 104. For example, the second pair of wires extends such that data packets transmitted from base station 103 with a destination of the second audio-order placement sub-system (e.g., by virtue of the addresses used in the data packets) are transmitted through (first) audio-order placement sub-system 101.
