Abstract: The present invention provides an antenna assembly which includes a capacitively coupled array of two or more inverted-L antennas. According to a preferred embodiment, the antenna assembly preferably may include: a receive resonator, a transmit resonator and a coupled bar which capacitively feeds the resonators. The receive resonator is preferably formed as an inverted-L antenna and the transmit resonator is preferably formed as an inverted-L antenna.

Abstract: The present invention relates to a system, method and apparatus for transmitting data reports at adjustable reporting rates based on detected rates of change in the heading of a tracked asset. According to a preferred embodiment, upon detection of a heading change, the device of the present invention may preferably power a location detection device (e.g., a GPS receiver or the like) to determine an accurate location. At the same time, the asset device may preferably monitor and store both the current heading and the rate of change of the heading. Based on the detected rate of change of the heading, the system may preferably select and update a report frequency based on a lookup table. Preferably, the lookup table may be based on a correlation between a given rate of heading change and predetermined temporal sample rates. According to a preferred embodiment, the higher the rate of change in heading may correspond to a higher temporal sample rate.

Abstract: A system and method for frost detection and frost mitigation for an imaging device within a container interior. According to a first preferred embodiment, the system preferably may include an imaging device having one or more LED light sources for illuminating the container interior. According to a preferred embodiment, the system may preferably first receive digital images from the imaging device along with one or more detected sensor inputs. Thereafter, the system may preferably calculate the potential for frost on or around the imaging device based on one or more sensor inputs which may include the imaging device temperature in combination with a door open signal, a detected light level or the like. The system may then preferably analyze the digital images during times of likely frost events using a frost detection algorithm which detects the presence of frost based on image characteristics derived from previously captured images with known frost levels.

Abstract: The present invention provides an improved network architecture which allows for many unique and specific interactions between LoRa networked devices, while still maintaining the security, range and low energy benefits of LoRa and LoRaWAN networks.

Abstract: The present invention provides a system, method and apparatus for determining the status of coupled assets during transport. According to a first preferred embodiment, a method of the present invention preferably includes triggering a set of tracking devices to transmit time stamp data indicating when the tracked assets cross pre-set speed thresholds. The present invention preferably further includes comparing the received time stamp data to equivalent data points from other assets and identifying unique pairs of assets which crossed the same speed thresholds at similar times and positions (i.e. matching velocity profiles). The system then designates the unique pair of assets as coupled and may apply custom tracking rules and power saving algorithms to the coupled assets.

Abstract: The present invention provides an antenna array which includes a structure in the form of a hexagonal pyramid with a flat top surface/facet. According to preferred aspects, the pedestal support of the present invention preferably further includes six side facets which are preferably disposed 60 degrees from each other. Preferably, each side facet preferably supports a patch antenna and the top facet supports a top/zenith antenna. According to a preferred embodiment, the azimuth antennas may be offset from the ground plane by an angle between 20 and 60 degrees. The zenith antenna is preferably substantially parallel to the ground plane.

Abstract: The present invention preferably includes a monitoring device which is able to monitor both signals from the cab and the contents of a trailer/container. According to a preferred embodiment, the monitoring device may transmit monitoring signals (i.e., RF, ultra-sonic, IR) within the trailer/container and receive responsive signals/feedback indicating the status of the container interior. According to preferred embodiments, the monitoring device of the present invention may preferably receive data/signals from sensors internal to the container.

Abstract: An automatic identification system (AIS) communications payload for a space vehicle traveling in earth orbit includes an antenna; a receiver connected to the antenna to receive an AIS signal including a reported vessel position transmitted from a vessel; a processor to process the received AIS messages and determine the accuracy of the reported vessel position; and a transmitter to transmit the processed AIS messages and the determined accuracy to a ground earth element. The processor may be configured to determine a position of the space vehicle; compare the reported vessel position to the space vehicle position; and determine the accuracy of the reported vessel position based on the comparison. The processor also may be configured to flag the AIS message as suspect when the reported vessel position is determined to be inaccurate.
