We present Hermes – a novel, low-cost, wireless, batteryless, energy harvesting system for aerial vehicles for sensing wind speed and Angle of Attack (AoA) concurrently. Hermes comprises a set of piezoelectric films which flutter due to incoming wind and the characteristics of this aeroelastic flutter are utilized for determining the wind speed and AoA of the head-wind. Hermes consists of five piezoelectric flags that are mounted on rigid clamps specifically placed at different angles.

In this dataset, based on a beam sweeping experiment in the 60 GHz band in an indoor environment, we provide the acquired IQ data samples (containing the announced TX antenna weighting vectors (AWV) index as information) for the given RX AWV index, location, and carrier frequency. We also include the information obtained after processing the PPDU in IQ data.

This file contains real GNSS data collected from a suburban region to a dense urban region in Ottawa. For the interest of the work, only GPS data are collected. The data are collected using two Ublox GNSS units (receivers), namely EVK-M8T and EVK-M8U. EVK-M8T is a timing product that can provide precise timing information for post-processing. EVK-M8U is a product that features dead reckoning mode, making this product reliable even in urban canyons. The data are in the format of UBX, NAV, and OBS. The UBX file is outputed directly by the receiver using u-center (software).

The Berlin V2X dataset offers high-resolution GPS-located wireless measurements across diverse urban environments in the city of Berlin for both cellular and sidelink radio access technologies, acquired with up to 4 cars over 3 days. The data enables thus a variety of different ML studies towards vehicle-to-anything (V2X) communication.
The data includes information on:

The development in the automation sector and aircraft design has enabled enormous innovations in the urban aviation sector, which includes Advanced Air Mobility (AAM). AAM includes the on-demand air transportation of goods and passengers using the drone between aerodromes within Air Corridors. Air Corridors are an integral part of AAM, a performance-based controlled airspace where drones follow a specific set of protocols. This includes appointing the Skylane, route availability, traffic control, collision avoidance, etc.

Five users aged 23, 25, 31, 42, and 46 participated in the experiment. The users sat comfortably in a chair. A green LED of 1 cm diameter was placed at a distance of about 1 meter from a person's eyes. EEG signals were recorded using g.USBAmp with 16 active electrodes. The users were stimulated with flickering LED lights with frequencies: 5 Hz, 6 Hz, 7 Hz, and 8 Hz. The stimulation lasted 30 seconds. The recorded signals were divided into the data used for training, the first 20 seconds, and the data used for testing, the next 10 seconds, for each signal.
