Abstract: The system and method for a chip-scale surface-mount technology (SMT) packaging method for semiconductor devices. The chip-scale SMT package uses an air-cavity lid to protect the active face of a MMIC, or other device either active or passive, from the environment. In some examples, the cover provides electrical routing. In some examples, the cover also provides electromagnetic shielding. In some cases, the Au semiconductor devices bond pads which are converted to a Pb/Sn compatible metal.

Abstract: A mixer device is disclosed, which is fabricated as a bipolar-complementary metal oxide semiconductor (BiCMOS) integrated circuit device, to provide improved linearity and dynamic range, at higher operating frequencies. A mixer device configured according to an embodiment includes a driver circuit comprising bipolar junction transistors (BJTs) to convert a local oscillator signal to a high slew-rate gate drive signal. The driver circuit is configured as a quasi-complementary driver employing NPN BJTs. The mixer device further includes a mixer circuit comprising CMOS field-effect transistors (FETs) configured to mix an input signal with the gate drive signal to generate an output signal through the application of the gate drive signal to the gate port of the CMOS FETs. The mixer device further includes a voltage biasing circuit to provide a biased body voltage to the FETs to allow overdriving to a negative voltage relative to the body voltage.

Abstract: A mid-body which a cylindrical housing which defines a longitudinal axis and has an interior compartment. A guidance controller is housed within the mid-body for controlling flight. A plurality of wings are connected to the housing and each of the wings is movable into a deployed position to provide guidance during flight. The mid-body has an access window which facilitates communication between the interior compartment of the housing and an external environment. A normally door covers the access window, but when the door is moved, relative to the access window, into an open position, communication between the interior compartment and the external environment is established. An optical sensor is accommodated within the interior compartment and the optical sensor, once the door is moved relative to the access window, can view the external environment and supply data to the guidance controller for controlling operation of the plurality of wings during flight.

Abstract: Apparatus and method are disclosed for engaging a guide pin for installation or removal. The tool has a housing with a plunger positioned within the housing. A support tube has at least two extensions that protrude from the housing when an engagement mechanism is depressed and grips the guide pin when the engagement mechanism is released.

Abstract: Techniques are provided for implementing a portable spectrum analyzer. An example system, according to an embodiment, includes a signal analyzer including an RF receiver to receive RF signals from an antenna, an analog-to-digital converter to generate a sampled signal based on the received RF signals, and a signal analysis co-processor to perform cognitive scanning analysis of the sampled signal. The cognitive scanning analysis includes detection, identification, and characterization of digital/analog signal(s) embedded in the sampled signal. The system may further include a communications interface circuit to provide communication between the signal analyzer and an associated mobile host platform (e.g., smartphone). The communication includes transmitting results of the cognitive scanning analysis to the mobile host and receiving parameters from the mobile host to control the operation of the cognitive scanning analysis. The signal analyzer and mobile host are coupled through a shared enclosure such as a hinged case, sleeve, or wallet.

Abstract: A system and method for cooling electronics with compressed gas cylinders. A small, lightweight, scalable cooling system provides portability and cooling for electronic components in remote areas. In some cases one or more compressed gas cylinders are used with a metering valve and a temperature sensor to release gas into an expansion chamber or channels in thermal contact with a heat sink that is in thermal contact with an electric component.

Abstract: The system and method of implementing a high reliability flash memory recorder comprising warm spare and error code correction bytes across several multi-chip modules. The use of redundant field programmable gate arrays and/or processors for command and control increases redundancy. The system and method has lookup table-based mechanisms combined with programming to determine when to substitute a warm spare byte as well as when to declare a block of memory as “bad” and no longer to be used. The system may use multiple memory banks with power switching per bank to reduce power consumption as well as increase reliability when the array is not being accessed.

Abstract: A battery door assembly for a battery compartment is disclosed. The battery door assembly includes a battery cover, glide track, a spring-loaded button, a locking tab and a set of hinges. The set of hinges is pivotally connected to a chassis of a scope. The locking tab keeps the battery cover from opening. The battery cover can be unlocked by first applying pressure on the spring-loaded button, and then sliding the spring-loaded button and the locking tab from one end of the glide track to another end of the glide track while maintaining the applied pressure on the spring-loaded button.

Abstract: The Quad Cell permits measurement of four quadrant signal powers simultaneously, metrics which are equal when the laser spot is at the desired zero location, at the center of the cell, the origin of the cells' axes. A control action acts upon the Quad Cell signals to move the laser spot toward the origin of the axes bisecting the four quadrants of the cell, moving the laser spot to the origin to achieve a null in the difference between these four signal levels.
