Harris Corporation is an American Florida-based international telecommunications equipment company that produces wireless equipment, electronic systems, and both terrestrial and spaceborne antennas for use in the government, defense, and commercial sectors. Headquartered in Melbourne, Florida, the company has approximately $5 billion of annual revenue and more than 14,000 employees — including nearly 6,000 engineers and scientists.The company is the largest private-sector employer in Brevard County, Florida . The company was the parent of Intersil . Most of the wireless start-ups in South Brevard County were founded and are staffed by former Harris Corporation engineers and technicians. The company's Digital Telephone Systems division was sold to Teltronics. In 2009, Harris was one of the top 100 federal contractors.In January 2015, Wired Magazine ranked Harris Corporation -- tied with U.S. Marshals Service -- as the number two threat to privacy and communications on the internets.

A method of making an electronic device may include forming at least one circuit layer that includes solder pads on a substrate and forming at least one liquid crystal polymer (LCP) solder mask having mask openings therein. The method may also include forming at least one thin film, resistor on the LCP solder mask and coupling the at least one LCP solder mask to the substrate so that the at least one thin film resistor is coupled to the at least one circuit layer and so that the solder pads are aligned with the mask openings.

Systems (100) and methods (400) for providing Digital Selective Calling (DSC) based services. The methods involve: using Space-Born Maritime (SBM) receivers of satellites (104) deployed in space as a satellite constellation to collect and process DSC emergency messages transmitted from DSC transmitters of terrestrial radios; using the satellites to position validate the DSC emergency messages; determining first positions of the DSC transmitters in transit based on geolocation data and time location data respectively assigned by the satellites to the DSC emergency messages; and validating the first positions to more precise second positions based on results of cross-correlations of the geolocation data and time location data with Automatic Identification Systems (AIS) data obtained for the DSC transmitters.

Systems (100) and methods for co-channel separation of communication signals. The methods involve: simultaneously receiving a plurality of communication signals transmitted at disparate relative Doppler frequencies from different locations within a multi-access system; performing matched filtering operations to pre-process each of the plurality of communication signals so as to generate pre-processed digitized samples using a priori information contained in pre-ambles (302, 304) of messages present within the plurality of communication signals; using estimated signal parameters to detect the plurality of communication signals from the pre-processed digitized samples; and demodulating the plurality of communication signals without using a Viterbi decoder.


An electronic device may include a speaker, and audio circuitry coupled to the speaker. The audio circuitry may generate digitized samples of an audio waveform signal, and compare each digitized sample of the audio waveform signal to a threshold. The audio circuitry may when a given digitized sample is above the threshold, then apply a compression operation to the given digitized sample and successive digitized samples for a set time period, and when the given digitized sample is below the threshold and not within the set time period, then not apply the compression operation.

Method and system for Single Event Latchup (SEL) current surge mitigation involves monitoring data signals for a protected device (106) and deriving from them a detected signature comprised of one or more detected signature vector components. The detected signature vector components are compared to previously stored signature vector components. Based on the comparing, the system selectively differentiates between the occurrence of standard power surges associated with normal operation of the protected device, and a non-standard current surge which requires cycling power of the protected device for continued proper functioning of the protected device.


An optical filter device may include an optical fiber having a core and a cladding surrounding the core, the optical fiber having a tapered portion. The optical filter device may include an index selectable material surrounding the tapered portion and having an index of refraction being selectable based upon a physical characteristic. The optical filter device may include a device configured to change the index selectable material to select the index of refraction to selectively filter out a mode within the optical fiber.


An RF communications device may include a circuit board having a dielectric layer and conductive traces, one of the conductive traces defining a transmission line. The RF communications device may also include an RF transmitter carried by the circuit board and coupled to the transmission line, and RF switching circuits, each RF switching circuit including a substrate having a tapered proximal end coupled to the transmission line, and a distal end extending outwardly on the convex side of the transmission line. Each RF switching circuit may include a series diode, and a shunt diode coupled to the series diode, the series diode extending from the tapered proximal end and across an interior of the substrate.

A filter for a radio receiving device doubles a sample size of a digital baseband signal to form an enhanced data set and after widowing performs a Fast Fourier Transform (FFT) to facilitate calculation of instantaneous magnitude values and average magnitude values for each of a plurality of frequency bins. A noise floor is calculated based on the average magnitude values of a plurality of the frequency bins, and the noise floor is then used to identify frequency bins which contain an interfering signal. If it is determined that a frequency bin contains spectral energy associated with an interfering signal, then the instantaneous magnitude value of the frequency bin is selectively reduced, after which an inverse FFT operation and inverse window operation is performed.

A model includes model layers on which a wireframe representation of objects located at geographic coordinates is stored in a memory such that surface detail of the objects increases from a base model layer to an uppermost model layer. Digital data layers stored in the memory that encompass digital coordinates corresponding with the geographic coordinates. Digital content for augmenting scenes is stored on pre-selected digital data layers at pre-selected digital coordinates on those layers. One or more of the digital data layers are logically linked with one or more of the model layers. When the location and spatial orientation of a mobile device in which a scene is viewed is received, the digital content on the digital data layer logically linked to one of the model layers is transmitted over a wireless communication channel to the mobile device.


Systems (100) and methods (600) for generating encrypted data. The methods involve: combining a cryptographic key with state initialization bits to generate first combination bits; producing a first keystream by performing a permutation function using the first combination bits as inputs thereto; and using the first keystream to encrypt first data (e.g., authentication data or message body data) so as to produce first encrypted data. The permutation function comprises a round function that is iterated times. The round function consists of (1) a substitution layer in which the first combination bits are substituted with substitute bits, (2) a permutation layer in which the substitute bits are re-arranged, (3) a mixing layer in which multiple of the permutation layer are combined together, and (4) an addition layer in which a constant is added to the output of the mixing layer.
