  • Off-state isolation enhancement for feedback amplifiers
    Patent number: 9859849
    Abstract: A feedback amplifier having an improved feedback network including two cross coupled switches that isolate the amplifier from extraneous undesired electrical signals present in a system or network when the amplifier is turned off (i.e., in an off-state). The cross coupled switches interconnect two feedback paths of a feedback network to enable out-of-phase differential signals to be summed and effectively canceled. Further, the feedback amplifier provides on-stage advantages to enable different amplifier characteristics and parameter to be selectively engaged by turning on or turning off certain feedback networks.

  • Method for practicing carrier sense multiple access at the application layer
    Patent number: 9860918
    Abstract: A system and method for controlling a aradio transmitter from the application layer is presented. The method includes monitoring an uplink state of a shared channel at a cell manager and processing the uplink state, at least in part, in the application layer in the cell manager to produce processed uplink state. The processed uplink state is then broadcast in a control packet on a downlink of the shared channel to a subscriber manager. The processed uplink state is then further processed, at least in part, at the application layer in the subscriber manager to produce transmitter control data. The transmitter control data is then used control the radio transmitter.

  • Coating for light security
    Patent number: 9851177
    Abstract: A night vision system includes an eyepiece and a video camera to capture a video image that can be remote to the eyepiece. The eyepiece includes an optical device with a front side and a back side. A splitting surface within the optical device reflects some of a video image toward an eye of a user of the eyepiece, and the splitting surface further allows some light of an optical image received from in front of the eyepiece to past through the eyepiece to the eye of the user. The layer of switchable coating on the eyepiece can be switched between a transparent mode and an opaque mode by the user. When in an opaque mode no light can leave the front side of the optical device and only the video image can be seen through the eyepiece.

  • Providing coordinating location information using a gridded reference graphic (GRG)
    Patent number: 9830726
    Abstract: A system for real-time or near real-time coordination of personnel and a method for creating a gridded reference graphic (GRG) for use in such a system is provided. A GRG is created by obtaining imagery of an area a team is to be operating in, wherein the imagery is obtained from overhead, taken from a position substantially orthogonal to the central portion of the area of operation. A grid, which may then be further modified with labels allowing identification of areas within the grid, is then overlaid thereon, creating a GRG. The GRG may then be served to personnel and displayed on a user device. The system includes a GRG comprising scale images of an intended area of operation, a labeled grid overlaid thereon and a scale for measurement of distances wherein the GRG are dispersed among and displayed to personnel.

  • Network test system
    Patent number: 9825842
    Abstract: A network test system seeks to improve visibility into the real-time operation of a network system or subsystem of a spacecraft through the use of a port from each relevant network to a spacecraft test interface. The network test system includes a packet switch operatively coupled downstream from a SERDES receiver and operatively coupled upstream from a SERDES transmitter. The packet switch in conjunction with the signal replicator in the SERDES receiver taps off a data stream of the network activity so that the port allows an observation device to passively observe the network activity. The system is adapted to increase real-time observation of network activity without disturbing the network.

    Patent number: 9811720
    Abstract: A system and method for identifying an individual based, at least in part, on their gait is presented. First, acceleration data is received from an accelerometer carried by a person. The acceleration data corresponds to a gait of the person. Rotational invariant values that are independent of a rotational position of the accelerometer are calculated based, at least in part, on the acceleration data. A gait dynamics image (GDI) is calculated based, at least in part, on the rotational invariant values. The GDI is matched to one of a set predetermined GDIs to identify the person.

  • Non-adjustable pointer-tracker gimbal used for directed infrared countermeasures systems
    Patent number: 9778028
    Abstract: In a directed infrared countermeasure system, to assure parallelism between the line-of-sight to a target and the output beam, the input and output mirrors are fixedly attached to a uni-construction arm mounted to a rotatable azimuth platter to which internal mirrors are also fixedly attached. A system is provided for zeroing out alignment errors by developing an aim-point map for the gimbal that records initial alignment errors induced by manufacturing tolerances and uses the aim-point map error values to correct the output mirror orientation. The system also corrects for alignment errors induced by thermal gradients.

  • Automated code-generation for cross-language development, testing, and integration
    Patent number: 9778922
    Abstract: A system and method provide for easy sharing of data between different software languages. A method begins by creating a definition defining a data structure with a domain specific language. The definition is then input to a code generator which generates data structures and algorithms in a first software language. The same generator software also creates equivalent data structures and algorithms in a second software language that is different than the first software language. The two output implementations provide compatible utilities for marshalling and de-marshalling data back and forth between the first software language and the second software language without requiring further manipulation of the two implementations.
