    Abstract: A system for securely customizing a computing environment based on cryptographic protections includes providing a key device; bringing the key device proximate to a computing environment (510); beginning an authentication protocol when the user approaches the environment with the device; validating user to the key device (520); comparing certificates (525); unlocking/regenerating a device split key (530); if authentication of certificates is not valid, log & return (540); if it is valid, a full key is generated on the computing environment in volatile memory, and the full key unlocks personal settings on the computing environment (545). Using the computing environment with the personal settings (550); disconnecting (555); and logging activity (560). The device can be a smart phone. Bringing the key proximate to a computing environment (510) can initiate Bluetooth or other near field communications. Initial steps can include enrolling the key (505). The environment can be a vehicle.

    Abstract: The present disclosure provide a device, system, and method for generating, in an electrical device, a 1 bit or a 0 bit that is received in a switching circuit powered by a battery. The device, system, and method generates, in the switching circuit, a negative bias voltage and a positive bias voltage. The device, system, and method transmits the negative bias voltage and the positive bias voltage to a power amplifier. The device, system, and method turns the power amplifier from an off-state to an on-state in response to receiving the negative bias voltage. The device, system, and method amplifies, with the power amplifier, a power signal moving through power amplifier when the amplifier is in the on-state.

    Abstract: A system and method for using an embedded microprocessor in an RF amplifier. The use of an embedded microprocessor avoids manual calibration. The Microprocessor collects initial amplifier performance data based on a set of parameters and calculates the needed corrections. The microprocessor can change levels within the circuit to achieve those operating points. The embedded microprocessor sets voltage levels with internal circuitry and communicates this information externally through a serial communication port, or the like, to allow a user to communicate with and look at the amplifier data and readjust the internal bias levels, as needed. Thus, the internal microprocessor provides for calibration, self-testing, and monitoring of the RF amplifier and also functions as an in situ bias and temperature compensation controller for use in the presence of temperature variation and provides bias sequencing control to protect against improper applied timing of voltage inputs to the amplifier.

    Abstract: Systems are disclosed for navigating a missile to a target using a fixed sensor onboard the missile. In an embodiment, a system includes a launch platform traveling a pre-programmed route to deliver the missile within an area. The missile travels a first flight path through the area in effort to detect targets. If no targets are detected along the first flight path, the missile transitions to a second flight path, different from the first flight path, to locate targets off-axis relative to the first flight path. While the missile travels the second flight path, the sensor receives signal identifying a target located at a position off-axis relative to the first flight path. The missile then adjusts the second flight path to direct the missile to the target. In an example embodiment, the first flight path is straight or arced, while the second flight path is u-shaped, corkscrew-shaped, or spiral-shaped.

    Abstract: An antenna receiver has antenna elements that are arranged in an array and spaced apart from each other at a distance greater than one-half wavelength of the highest operating frequency of a signal that is to be detected by the antenna receiver. The antenna receiver has geolocation logic that uses the inter-element phase difference measurements to obtain a location of the signal source. The change in the inter-element phase differences enables the elements to be spaced apart at great distances, which is beneficial for the physical construction of the platform, as the elements may be easily placed at convenient locations for conformal aerodynamic properties.
