摘要： A communication system for the transmission of the sound portion of motion pictures or the like in drive-in theaters directly to automobile radios by means of an induction cable buried beneath the ground in the reception area in which automobiles viewing the motion picture are to be parked. The cable is of such design that when properly positioned and combined with an amplitude-modulated radio frequency signaling means, a relatively uniform amplitude-modulated electromatic field of the desired strength and of a frequency which is within the normal reception range of car radios (i.e. the standard broadcast band) is established throughout only the area where the automobiles are parked.To limit signal reception outside the designated parking area of a drive-in theater an interfering signal is transmitted by coupling audio-modulated radio-frequency energy to nearby electric power lines of overhead type or by means of a transmission line or cable adjacent and outside the theater area. The interfering signal employs the same radio frequency as is used by the induction cable in the reception area of the theater.

摘要： The present disclosure provides systems, methods, and computer program products for transmitting data to computing devices via audio communication channels. A computer-implemented method performed by one or more processing devices may include, for example, providing an audio token to a broadcasting device for broadcast via an audio communication channel, receiving the audio token from a user computing device, the audio token being received from the user computing device based on an audio broadcast of the audio token by the broadcasting device via the audio communication channel, and obtaining, in response to determining data that is associated with the received audio token, approval to process a payment transaction by at least in part transmitting the data to the user computing device.

摘要： A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

摘要： Methods, apparatus, and systems are described for monitoring at least one signal passing through a coupling connection from a first conveyance to a second conveyance, where the coupling connection has a network device that communicates on a wireless node network. Generally, the network device (e.g., an ID node) integrated in the coupling connection monitors the signal line passing through the coupling connection from the first conveyance to the second conveyance. The network device then detects data on the monitored signal line and records the detected data. Thereafter, the network device in the coupling connection transmits the detected data (e.g., a notification that the conveyances are disconnected, a change in power flowing between the conveyances, etc.) to another entity in the wireless network, such as a server or master node.

摘要： Embodiments are provided for syncing multiple electronic devices for collective audio playback. According to certain aspects, a master device connects (218) to a slave device via a wireless connection. The master device calculates (224) a network latency via a series of network latency pings with the slave device and sends (225) the network latency to the slave device. Further, the master devices sends (232) a portion of an audio file as well as a timing instruction including a system time to the slave device. The master device initiates (234) playback of the portion of the audio file and the slave devices initiates (236) playback of the portion of the audio file according to the timing instruction and a calculated system clock offset value.

摘要： An information system generates data, generates an audio token, associates the audio token with the data, and transmits the audio token along with the data to the account management system. The information system configures a broadcasting computing device to broadcast the audio token at a location. User computing devices at the location via an audio communication channel receive the broadcast token and retransmit the audio token to the account management system via a network. The account management system receives the audio token from a particular user computing device along with a request for data associated with the audio token, extracts the data associated with the audio token data, and transmits the data associated with the audio token to the particular user computing device.
