A drive-thru system includes a kiosk equipped with at least one omnidirectional antenna and at least one directional antenna, and a user equipment equipped with a processing unit and a communication unit.

A method and apparatus is disclosed for enabling synchronous capture of forward and return signals at a remote PHY device for detecting CPD. The remote PHY device provides the forward signal to and receives the return signal from a coaxial cable plant. The return signal contains an actual CPD signal generated by an interaction between the forward signal and a CPD source in the cable plant. The forward signal propagates from the remote PHY device to the CPD source and the actual CPD signal propagates from the CPD source to the remote PHY device all within a round-trip interval. The method comprises: capturing the forward signal from an output associated with the remote PHY device; generating from the forward signal a simulated CPD signal having frequencies in a return channel; band-limiting the simulated CPD signal to the return channel to produce a reference CPD signal; supplying the reference CPD signal to the remote PHY device; in the remote PHY device, receiving the reference CPD signal in the return channel; and (f) in the remote PHY device, capturing the return signal from the return channel over a capture duration of at least the round-trip interval. The reference CPD signal is used to detect the actual CPD signal from the return signal.

A method of detecting CPD in an HFC network that includes a remote PHY device (RPD) is disclosed. The RPD includes a transmitter, receiver, and diplexer having forward and return legs. The receiver receives a return signal from a cable plant via the return leg. The transmitter provides a forward signal to the cable plant via the forward leg. A portion of the forward signal leaks through the return leg and travels to the receiver. The return signal contains a CPD signal generated by the forward signal and a CPD source in the cable plant. The forward signal propagates from RPD to CPD source and CPD signal propagates from CPD source to RPD within a round-trip interval. The method comprises: (a) adjusting the capturing bandwidth of the receiver to include return and leaked forward signals; (b) operating receiver to capture return and leaked forward signals over a limited duration of at least the round-trip interval; and (c) detecting CPD signal by processing captured leaked forward and return signals.

An example system includes a server communicatively connected to a cellular base transceiver station having an RF coverage area and configured for RF communication with a first entity that is a transceiver device in the RF coverage area, wherein the server comprises a first publish-subscribe broker that is part of a publish-subscribe broker network that comprises one or more publish-subscribe brokers, wherein a second entity connected to any of the one or more publish-subscribe brokers in the publish-subscribe broker network accepts communications from the transceiver device if the second entity subscribes to data packets published by the transceiver device, and wherein the data packets published by the transceiver device are routed through the publish-subscribe broker to which the second entity is connected.

Described herein is an implantable medical device (IMD) that wirelessly communicates another IMD, and methods for use therewith. Such a method can include receiving one or more implant-to-implant (i2i) communication signals from the other IMD using a communication receiver of the IMD, measuring a strength of at least one of the one or more received i2i communication signals or a surrogate thereof, and updating a strength metric based on the measured strength or surrogate thereof. The method further includes determining, based on the updated strength metric, whether to increase, decrease, or maintain the sensitivity of the communication receiver of the IMD, and responding accordingly such that the sensitivity is sometimes increased, sometimes decreased, and sometimes maintained. The method can also include selectively causing a transmitter of the IMD to transmit an i2i communication signal to the other IMD requesting that the other IMD adjust its transmission strength.

A queue management method, system, and recording medium include Selective Acknowledgments (SACK) examining to examine SACK blocks of the forwarder to selectively drop packets in the forward flow queue based on a reverse flow queue and MultiPath Transmission Control Protocol (MPTCP) examining configured to examine multipath headers to recognize MPTCP flows and examine the reverse flow queue to determine if redundant data has been sent such that the dropping drops the redundant data.

Dynamically identifying and utilizing an opportunistic device by performing at least the following within a discovery offloading module: receive an offloading alert message from a service device, wherein the offloading alert message indicates the service device is unable to provide one or more services to the client device, receive a discovery message from a candidate device, wherein the discovery message indicates the candidate device is capable of performing the services provided to the client device, select, using the dedicated execution environment, an opportunistic service device based on the discovery message from the candidate device; and trigger the restart of host execution instruction within the client device by obtaining the one or more services from the opportunistic service device, wherein the discovery offloading module operates independently from the host execution instructions within the client device.

To prevent a delay in detection of a fault and the like and to cut down a load on a management side while making transmission of data appropriate in consideration of importance and properties of each type of the data in a case in which a large amount of data is transmitted from management target apparatuses. Items with high priority are processed first, and items with a low priority are allowed to be thinned out in accordance with priority and a weight that a management system 10 defines for each data item, thereby reducing a load. The thinning out is performed by limiting the number of data items to be processed once in accordance with a load level. Data acquisition intervals and priority for each item are dynamically changed by reflecting the importance of the data of each item and a change thereof. Trends of data and the like distributed using telemetry are observed and are fed back to load control through control using an AI or a rule base. In a case in which distribution intervals of each data item are changed, the distribution intervals are changed to a multiple of a basic cycle to curb influences on correlations among the items.
