2. The luma sampling frequency is 13.5 MHz, the chroma sampling frequency is 13.5 × 0.5 = 6.75 MHz, and the components are quantized to 8 bits. In the 525/60 system, the luma component of the frame has active dimensions of 720 pels × 480 lines and the chroma components have 360 ...
The proposed sensor system based on ceramic resonators and circular waveguide structures offers a novel solution for controlling the quality of tool clamping in a tool-receiving socket interface. Compared to current solutions this sensor system enables both an easy, cost-effective production and a high...
Horn sound generating system and method using ultrasound sensorThe present invention relates to a technology that generates a siren through the driver's operation, but it is generated outside the vehicle (at a certain point in front), which can reduce the siren sound flowing into the interior ...
So, the transmission of lower frequency RF signals can be non-line-of-sight, which makes them suitable for macro cell coverage and point-to-multipoint communications. However, the bandwidth and capacity of a low frequency RF spectrum are limited. Lower frequency signals also require bigger size...
sensor performed continuous surveillance of flying insects for 80 days126. The device recorded light backscattered by insects transiting through its laser beam and compiled information about each insect’s wing beat frequency, transit time across the beam, and the ratio of its wings to body ...
The primary technology employed for lightning detection is VLF/LF (Very Low Frequency / Low Frequency) lightning sensors, as detailed in the works of Cai et al.31,32 and Wang et al.33. The network configuration consists of these nine sub-stations, positioned at distances spanning 20–40 ...
A sensor system for detection of a gaseous chemical substance is provided, which comprises an optical sampling cell holding a sampling chamber of a volume of at most 20mm 3 , a light emitter and a light receiver. The sampling cell is adapted for free-space propagation of the light beam. Wi...
In the absence of this alarm signal (when TLHONs are silenced), flies are still able to perform escape turns, but they do so at lower frequency and often deeper into the thermal gradient. Modeling the impact of a derivative signal on fly behavior...
