In this context, the master node is configured to authenticate the at least two slave nodes with a pair-wise authentication key corresponding to each pair of master node and slave nodes. The master node is further configured to generate a group authentication key common to the plurality of nodes. Furthermore, the master node is configured to encrypt the group authentication key with the pair-wise authentication key for each respective pair of master node and slave nodes, thereby generating a respective encrypted group authentication key. Moreover, the master node is configured to communicate the encrypted group authentication key to the respective slave nodes.

Abstract: A method for producing a filter, the method comprising
providing a first layer above a substrate;
providing a block copolymer layer above the first layer;
converting the block copolymer layer to a mask by selectively removing domains of the block copolymer layer;
etching pores through the first layer in regions exposed by the mask; and
forming a channel through the substrate, the channel being configured to provide fluid communication between a first and a second end of the channel, the first end of the channel being directly below the etched pores of the first layer,
whereby fluid passing through the channel and the pores is filtered by the pores, when the filter is in use.-

Abstract: An analog-to-digital converter, ADC, is provided. The ADC comprises a comparator having a first input and a second input. The ADC further comprises a first digital-to-analog converter, DAC, and a second DAC configured to receive a first and a second digital reference signal, respectively. The digital reference signals (Dref) represent a signed binary value. The ADC is configured to compare input voltages (Vin), based on a first sampled input signal of a differential input signal and the first digital reference signal, and based on a second sampled input signal of the differential input signal and the second digital reference signal and, based on said comparison, adjust the reference voltage so as to approximate the differential input signal.

Abstract: A method for generating an ultra-wideband signal is provided. The method comprises the steps of generating at least one ultra-wideband pulse envelope comprising a main pulse and a precursor pulse, the precursor pulse being shorter in length and lower in amplitude compared to the main pulse, and modulating a carrier signal in amplitude such that the envelope corresponds to the at least one ultra-wideband pulse envelope and such that the carrier signal within the main pulse is phase-shifted with respect to the carrier signal within the precursor pulse.

Abstract: Example embodiments relate to methods and systems for processing analog signals. One example method for processing an analog signal includes modulating the analog signal using a chopping signal with a chopping frequency fchop to generate a modulated signal. The method also includes amplifying the modulated signal to generate an amplified signal. Additionally, the method includes low-pass filtering the amplified signal to generate a filtered signal that includes at least one harmonic of the modulated signal. Further, the method includes sub-sampling the filtered signal and performing a correlated double sampling operation by subtracting samples at the chopping frequency.
