Abstract: Systems, methods, and circuitries are provided for determining the likelihood that a malicious signal component is present in a UWB signal. In one example, a UWB receiver device is configured to receive a UWB signal during a ranging round; correlate the received UWB signal with a reference STS template to generate a correlation output; based on the correlation output, compute a channel quality indicator that characterizes a noise level of the channel; compute an attack-detection figure of merit (A-D FOM) based on the channel quality indicator, a block error of the received UWB signal, or a frequency error of the received UWB signal; and provide data indicative of the A-D FOM to a controller device.

Abstract: Some aspects of the present disclosure relate to a detection system having a plurality of wide-band transceivers and a controller circuitry communicatively connected to each of the transceivers. Each transceiver comprises a transmitter and a receiver. The controller circuitry is configured to trigger a subset of the transmitters to transmit a first set of signals for receipt by a subset of the receivers, establish a baseline channel-impulse-response (CIR) profile for the system based on the receipt of the first set of signals, subsequently trigger the subset of the transmitters to transmit a second set of signals for receipt by the subset of the receivers, establish a first current CIR profile for the system based on the receipt of the second set of signals, and detect a non-transmitting target in proximity to the system based on the baseline CIR profile and the first current CIR profile.

Abstract: An article of apparel includes a composite material. The composite material includes a pliable first layer and a resilient second layer, where the first and second layers are secured to each other via a patterned strand network. In forming the composite material, the second layer is stretched and maintained under tension while the first layer is secured to the second layer via the patterned strand network. The tension on the second layer is then released, resulting in contraction of the second layer in relation to the first layer and an outward buckling or protrusion of the first layer in relation to the second layer to form protruding cells along the composite material that are bounded by portions of the patterned strand network. The patterned strand network can be formed using embroidery with one or more auxetic patterns in the stitching.

Abstract: Techniques are disclosed to detect deep fading caused by magnitude drop and rapid phase change on channels within a frequency band of a narrowband wireless radio operating in a BMS-like environment with strong multipath. The techniques may identify an interference channel, a deep fading channel, or a weak signal channel. A channel assessment algorithm may receive packets on one of multiple channels to determine a received signal strength for each packet associated with the channel. The algorithm may determine a PER associated with the channel based on a number of packets received in error and a difference between the received signal strength of each packet and a reference signal strength associated with other channels of the frequency band. The PER may be compared with a PER threshold. The channel may be excluded from use by the wireless radio if the PER for the channel is greater than the PER threshold.

Abstract: Disclosed herein are systems and methods that do not require loading data into memory to perform daily activities of an application. The data from an external source can be accessed externally and utilized (for example, in a workbook or via a dashboard, etc.) the same way as in-memory data. This is useful when an external data set is too large to fit in the memory. In this manner, all the data that is needed can be stored in an external table that may be accessed as needed.

Abstract: A method can include, by operation of controller circuits, determining a higher interference resistance (HIR) location coordinate (PIN) for a route between the wireless device and a target location. A wake message can be transmitted according to a first wireless protocol. In response to receiving an awake message according to a second wireless protocol, a location and quality value for the awake message can be stored. In response to being within a predetermined proximity of the HIR activation PIN without having received the awake message, a HIR wake message can be transmitted. In response to acquiring stored location and quality values, an HIR activation PIN can be selectively changed. A first wireless protocol can consume less power or be less resistant to interference than a second wireless protocol. Corresponding devices and systems are also disclosed.
