摘要： Aspects of the present disclosure relate generally to night-vision systems and more specifically to an integrated micro-display module with a flex circuit. One example illustrated herein includes a method of upgrading a night-vision system. The method may include attaching a flex circuit to an intensifier module, in which the flex circuit includes one or more light detectors and extending beyond a leading edge of the intensifier module. The method may include inserting the intensifier module into a housing and folding the flex circuit to expose the one or more light detectors. The method may further include optically coupling a display unit to an output side of an intensifier module of the night vision system. The display unit may be configured to display graphical content in a field of view together with night-vision images from an output of the intensifier module of the night-vision system.

摘要： Indicating to a receiver node in a network that the receiver node should begin tracking signal to noise ratio (SNR) of a received signal for a new power and rate (PAR) interval for data sent from a transmitter node. A method includes determining that a new PAR interval is beginning. The method further includes adding an identifier to a data block. The identifier corresponds to the new PAR interval. The method further includes sending the data block from the transmitter node to the receiver node, where the receiver node will use the identifier to determine that a new tracking interval of SNR should be performed for the data block and subsequent data blocks having the identifier.

摘要： An electronic device may include an electronic circuit, a heat sink thermally coupled to the electronic circuit, and spaced apart cooling fins extending from the heat sink. Each cooling fin includes a circuit board and a cooling device mounted thereon. The cooling device may have a conductive trace layer on the circuit board defining an electromagnet, a mounting member extending upwardly from the circuit board, a fan blade coupled to an upper end of the mounting member to be movable in a rocking motion about an axis defined by the mounting member, and a permanent magnet carried by the fan blade and responsive to the electromagnet.

摘要： A nightvision system includes an underlying device that provides output light in a first spectrum. A transparent optical device transmits light in the first spectrum from the underlying device through the transparent optical device. The transparent optical device includes an active area of a semiconductor chip. The active area includes active elements that cause the underlying device to detect light from the underlying device and transparent regions formed in the active area which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through from the underlying device to a user. An image processor processes brightness maps produced using light detected by the first plurality of active elements. An illuminator coupled to the image processor inputs light into the underlying device based on image processing performed by the image processor.

摘要： Systems and methods comprising: receiving a signal (S) having a first interfering signal component (FISC); generating a replicated SOI (RSOI); and iteratively performing a process to obtain residual errors for FISC. The process involves: modifying an amplitude of RSOI; obtaining a reference signal (RS) by removing RSOI with the modified amplitude from S; analyzing frequency of RS to obtain an estimated carrier frequency and an estimated symbol rate for FISC; generating a remaining signal by removing, from FRS, a signal having the estimated carrier frequency and symbol rate; and determining a residual error of the remaining signal. Parameters for FISC are then set equal to the estimated carrier frequency and symbol rate that are associated with a lowest residual error. The parameters may be further refined in accordance with another process which involves iteratively modifying a symbol rate of FISC. Yet another process may be performed to determine filter parameters.

摘要： A multipoint relay (MPR) wireless network may include spaced apart nodes, with each node including wireless transceiver circuitry, beacon circuitry, and a controller coupled to the wireless transceiver circuitry and beacon circuitry. The controllers may be configured to operate the beacon circuitry to determine a respective link strength metric for each potential link between nodes, assign a set of nodes from among the plurality of nodes to function as gateway nodes and assign other individual nodes to communicate via respective gateway nodes based upon the respective link strength metrics to define the MPR network so that one-hop links have a strongest link strength metric, and operate the wireless transceiver circuitry for communications over the MPR network.

摘要： Signal processing to compensate for gain control output spikes caused by steps in a digital step attenuator. A method includes receiving a changing power input signal at a receiver. The method includes determining that a change in power of the input signal will cause a step attenuator to change its attenuation in a step of a predetermined amount. The method further includes based on determining that the change in power of the input signal will cause a digital step attenuator to change its attenuation in a step of a predetermined amount, causing a variable attenuator to change its attenuation by an amount related to the predetermined amount at a time coinciding with a time when the step attenuator changes its attenuation by the predetermined amount. The method further includes outputting a gain-controlled output signal resulting from applying the step attenuator and the variable attenuator to the changing power input signal.
