Abstract: A method (50) of, a node device (100) and a computer program product arranged for alerting node devices in a network of operatively interconnected node devices by transmitting an alerting message comprising a geographic location address of an originator node device (21) transmitting the alerting message and a moving direction (12) of an object (11) receiving service from the originator node device (21). When a receiving node device (24, 25) determines, based on its geographic location address, the geographic location address of the originator node device (21) and the moving direction (12), that the object (11) is approaching the receiving node device (24, 25), it transmits the alerting message comprising the geographic location address of the originator node device (21) and the moving direction (12).

Abstract: Piston mode Lamb wave resonators are disclosed. A piston mode Lamb wave resonator can include a piezoelectric layer, such as an aluminum nitride layer, and an interdigital transducer on the piezoelectric layer. The piston mode Lamb wave resonator has an active region and a border region, in which the border region has a velocity with a lower magnitude than a velocity of the active region. The border region can suppress a transverse mode.

Abstract: Method of and device for commissioning a lighting system including a plurality of lighting fixtures positioned at a plurality of physical locations. The lighting fixtures are mapped to a respective physical location using signals generated by the lighting fixtures and received at multiple detection locations by at least one or more detecting devices integrated with or external to the lighting fixtures. In particular, the method applies a probability-based algorithm to distances from the physical locations to multiple detection locations, and RSSI levels of signals received at the detection locations to determine a probability of having a respective lighting fixture located at a respective physical location. The method provides for commissioning the lighting system without traversing all the physical locations of lighting fixtures, resulting in a reduction of both work load for conducting the commissioning of the lighting system and processing power required for the commissioning.

Abstract: An adjustable coupler assembly for a truck assembly of a model railroad car includes an adjustment arm engaged with the truck assembly. The adjustment arm is selectively movable with respect to the truck assembly in a first direction. A coupler pocket is engaged with the adjustment arm. The coupler pocket is selectively movable with respect to the adjustment arm in a second direction. A coupler is pivotably attached to the coupler pocket. The adjustment arm and the coupler pocket are selectively movable to adjust the coupler in the first and second directions with respect to the truck assembly.
