The present invention disclose an occupancy detection device and related system and method for detecting presence of at least one person at or near a table or in a swimming pool with at least one sensor indicating an occupancy status locally with at least one light source and communicating it to at least one mobile device by means of at least one wireless communication method. The occupancy detection device, with the use of at least one sensor, at least one additional status is communicated to at least one mobile device. A plurality of occupancy detectors can be connected in a mesh or a star network and communicate to at least one mobile device by a wireless communication method or combinations of a wired and a wireless communication methods.

A method of communicating devices using virtual buttons comprises receiving, by a user device, a store code and transmitting, by the user device, the store code to a server; searching, by the server, for virtual buttons corresponding to the store code, and transmitting, by the server, to the user device the virtual buttons corresponding to the store code; providing, by the user device, an interface configured to receive a location identifier and button selection input among the virtual buttons received from the server, and transmitting, by the user device, the location identifier and the button selection input to the server; transmitting, by the server, to a staff device the location identifier and the button selection input; and receiving, by the staff device, the location identifier and the button selection input and displaying information associated with the location identifier and requested service corresponding to the button selection input.

A paging system comprise paging buttons configured to transmit a first signal including a paging request; a server configured to: receive the first signal, identify which of the paging buttons transmit the first signal received by the server, and transmit to at least one portable device a second signal including information on an identifier corresponding to the identified paging button that transmits the first signal, and the paging request; and at least one portable device configured to: display the identifier corresponding to the identified paging button and/or the paging request based on the second signal, and transmit to the server a third signal in response to an acceptance input responded to the paging request. The server transmits to at least one portable device a fourth signal confirming that the portable device transmitting the third signal is matched to the identified paging button in response to the third signal.

A means for food allergy management system, a smart AI driven restaurant menus on QR Code or barcode for enhanced dining experience is disclosed. This software invention brings Artificial Intelligence to restaurant menus, making them smarter, intelligent, enhanced and multilingual with advanced dish and item visuals and descriptions, strong analytics and hyperlinks to the meaning of industry terms. By bringing exceptional skills for content intelligence and ingredient safety management to menus, this invention fills the void on previously restaurant menus.

A paging system comprise paging buttons configured to transmit a first signal including a paging request; a server configured to: receive the first signal, identify which of the paging buttons transmit the first signal received by the server, and transmit to at least one portable device a second signal including information on an identifier corresponding to the identified paging button that transmits the first signal, and the paging request; and at least one portable device configured to: display the identifier corresponding to the identified paging button and/or the paging request based on the second signal, and transmit to the server a third signal in response to an acceptance input responded to the paging request. The server transmits to at least one portable device a fourth signal confirming that the portable device transmitting the third signal is matched to the identified paging button in response to the third signal.

A service request system comprises: a call bell device transmitting service request information in response to a customer's input; a first gateway device receiving the service request information through a local area communication; a service server connected to the first gateway device over an Internet and, in an online status, receiving the service request information from the first gateway device through the Internet; a staff terminal connected to the service server over the Internet and receiving the service request information from the service server through the Internet; a local server connected to the first gateway device and the staff terminal over the local area communication, monitoring availability of the Internet and, in an offline state, receiving the service request information of the call bell device from the first gateway device and transmitting the service request information of the call bell device to the staff terminal through the local area communication.

An apparatus for communicating the status of a consumable having a tubular housing with a channel, wherein the channel includes a proximal section and a distal section separated by an internal flange, a power module assembly including a coaster coupled on the proximal section of the tubular housing, a top cover, and a bottom cover coupled to the distal section of the tubular housing, a sensor coupled to the coaster for determining a level of beverage in a beverage container, and electronic circuitry for controlling a status indicator, wherein the sensor is in electrical communication with the electronic circuitry, wherein the status indicator is operably coupled to the sensor; and wherein the status indicator is covered by a lampshade.

A method of customer interaction includes receiving, by a management system, reservation information of a customer for a business location. The method further includes receiving, by the management system, a first message indicating an arrival of the customer at the business location. The first message is received by the management system from a lighting fixture that received the first message from a mobile device via a visible light transmission. The lighting fixture is located at the business location. The method also includes transmitting, by the management system, a second message to the mobile device in response to receiving the first message.
