Abstract: A multiple access point system includes a wireless network including a first channel and a second channel. The system further includes a first access point and a second access point co-located within a single physical location environment, a wireless backhaul connecting the first and second access points to the wireless network, and a processor configured to (i) assign the first channel as a primary channel of the first access point and the second channel as a primary channel of the second access point, and (ii) assign the first channel as a secondary channel of the second access point and the second channel as a secondary channel of the second access point. The primary channel of the first access point does not overlap with the primary channel of the second access point, and the secondary channel of the second access point overlaps with the first access point.

Abstract: Devices and nodes associated with a vehicle may communicate using a higher-level, common messaging protocol over an ad-hoc network to publish and subscribe to services, even though different nodes may utilize different types of links and channels. The network includes a rules node that is fixedly connected to the vehicle and that stores a set of rules. Given a possible publisher, subscriber, and/or a service, a node action is allowed or denied based on the set of rules. The rules may be generated or updated based on priorities, security levels, and/or characteristics of publishers, subscribers, their respective users, and/or services; a current dynamic condition; and/or user input. The rules node and at least one other node may be transported by the vehicle, and both transported nodes and nodes external to the vehicle may use the common messaging protocol to join the ad-hoc network, discover other nodes, authenticate, and publish/consume services.

Abstract: Devices and nodes associated with a vehicle may communicate using a higher-level, common messaging protocol over an ad-hoc network to publish and subscribe to services, even though different nodes may utilize different types of links and channels. The network includes a rules node that is fixedly connected to the vehicle and that stores a set of rules. Given a possible publisher, subscriber, and/or a service, a node action is allowed or denied based on the set of rules. The rules may be generated or updated based on priorities, security levels, and/or characteristics of publishers, subscribers, their respective users, and/or services; a current dynamic condition; and/or user input. The rules node and at least one other node may be transported by the vehicle, and both transported nodes and nodes external to the vehicle may use the common messaging protocol to join the ad-hoc network, discover other nodes, authenticate, and publish/consume services.

Abstract: An acoustical stack for use within an ultrasound transducer that has a center frequency has a poled piezoelectric material layer and at least one impedance matching layer. The poled piezoelectric material layer has top and bottom sides and is formed of poled piezoelectric material that has a first acoustic impedance. The poled piezoelectric material layer has a first thickness and the acoustical stack has an output electrical impedance based on the first thickness. The impedance matching layers are configured to be attached to the top and bottom sides of the poled piezoelectric material layer and have second or third thicknesses. The impedance matching layers are formed of one or more materials that have an acoustic impedance substantially similar to the first acoustic impedance. The poled piezoelectric layer and impedance matching layers form an acoustic resonance thickness. The center frequency of the transducer is based on the acoustic resonance thickness.
