    摘要： Some aspects of this disclosure are directed to implementing hardware-based obfuscation of digital data. For example, some aspects of this disclosure relate to a method, including performing a capture operation that loads a plurality of primary input (PI) bits into corresponding shift registers of a plurality of test data registers (TDRs) disposed on one or more digital semiconductor devices and configured to store a plurality of secret information bits. The method further includes performing a sequence of shift operations on the plurality of TDRs to obtain a plurality of output bits. The method further includes applying, by an authenticating processor, a derivation function on the plurality of output bits to extract the plurality of secret information bits thereby authenticating the one or more digital semiconductor devices.

    摘要： A foldable display device includes: a display panel including a foldable display area; a first base plate overlapping a portion of the foldable display area to guide folding of the display panel; a second base plate overlapping another portion of the foldable display area to guide the folding of the display panel together with the first base plate; a first rotor coupled to the first base plate to rotate around a first virtual rotation axis, a second rotor coupled to the second base plate to rotate around a second virtual rotation axis; a follower in contact with the first and second rotors to reciprocate in a first direction by rotation of at least one of the first and second rotors; and a bracket coupled to the first and second rotors to guide a rotation path of each of the first and second rotors.

    摘要： A method for determining a calibration function includes: calculating a first distance, between a distribution of target spectra and a comparison distribution of spectra; calibrating the distribution of target spectra with a first preliminary calibration function to form a first distribution of calibrated target spectra; calculating a second distance, between the first distribution of calibrated target spectra and the comparison distribution of spectra; determining that the second distance is less than the first distance; and setting the calibration function equal to the first preliminary calibration function.

    摘要： A feed-supplying system includes a feeder and a scale. The feeder includes a bin, a valve module and a monitoring module. The monitoring module controls the valve module to open an outlet of the bin to allow the feeder to supply feed, measures a vertical inside-bin distance, and outputs a notification when it is determined that an amount of stored feed is less than a threshold based on the distance. The scale supports the supplied feed, senses weight of a load thereon. When it is determined that an amount of the supplied feed has reached a threshold based on the weight, the monitoring module controls the valve module to close the outlet so as to stop the supply of the feed.

    摘要： A display device includes: a substrate; a bank having a first main opening and sub-openings extending from the first main opening; a first electrode and a second electrode on the first substrate and being spaced apart from each other in a first direction and extending in a second direction; a plurality of light-emitting elements on the first electrode and the second electrode and being spaced apart from each other in the second direction; a first connection electrode on the first electrode and contacting first ends of the light-emitting elements; and a second connection electrode on the second electrode and contacting second ends of the light-emitting elements. The first connection electrode is connected to the first electrode through a first contact, and the second connection electrode is connected to the second electrode through a second contact on the second electrode. The first contact and the second contact overlap the sub-openings.

    摘要： A circuit includes a clock generator, a frequency divider, and a first biasing circuit. The clock generator generates a clock signal of a first frequency. The frequency divider includes a first pair of cross coupled transistors. The frequency divider produces the clock signal of a second frequency. The first biasing circuit is coupled with the first pair of cross coupled transistors of the frequency divider. The first biasing circuit is adapted to enable a change in a transconductance of the first pair of cross coupled transistors to stabilize a phase angle between the clock signal at the first frequency and the clock signal at the second frequency.
