  • Patent number: 10644715
    Abstract: An analog-to-digital converter (ADC) module includes a plurality of frequency stacked ADCs. A splitter splits channels into two segments to transmit the signal through respective low pass and high pass filters to send the analog signal to a low frequency ADC and a high frequency ADC along each channel. When using a quad-tuner having four channels, there are eight ADCs: four high frequency ADCs and four low frequency ADCs. Typically, there is one ADC associated with each channel. Thus, a quad-tuner would be used with an ADC module having four ADCs. However, by splitting and filtering each channel and increasing the number of ADCs in the ADC module, the system, assembly, and method in the present disclosure is able to increase the frequency bandwidth throughput along legacy radio frequency (RF) cables on a platform without the need of replacing any legacy hardware or the legacy RF cables.

  • Patent number: 9560785
    Abstract: The mezzanine card system and method of use thereof provides a baseboard having opposing sides, each side configured to receive a mezzanine card thereon. A plurality of mezzanine cards are provided having integrated circuits, such as Field Programmable Gate Arrays, fixedly attached thereon. The mezzanine cards of the system reduce reprogramming time from about 15 months to about six weeks. This drastic reduction in reprogramming time provides great advantages for circuitry systems, especially when these systems are used within battlefield and electronic warfare technology. The surfaces of the baseboard are an Electroless Nickel, Electroless Palladium, and Immersion Gold (ENEPIG) plated finish.

  • Patent number: 7412310
    Abstract: A system and method of controlling activation of a power source of a hybrid electric vehicle. The method includes determining a vehicle speed, determining an operating state of a brake system, and controlling activation of the power source based on at least one of the vehicle speed and the operating state of the brake system.

  • Patent number: 6941198
    Abstract: A method for controlling activation of a power source of a hybrid electric vehicle. A hybrid electric vehicle has first and second power sources connected to a motor. The motor is connected to a transmission adapted to drive a vehicle wheel. The method includes comparing a vehicle speed value to first and second threshold values. If the vehicle speed value is less than the first threshold value, then the method determines whether a vehicle brake is released. If the vehicle speed value is greater than the first threshold value and less than the second threshold value, the method determines whether additional acceleration is demanded. The power source is activated if additional power is demanded or if the vehicle brake has been released. The power source is deactivated if the brake is engaged or if additional power is not demanded.

  • Publication number: 20050177206
    Abstract: A programming device used to program an implantable neurostimulator (INS) presents battery longevity information to a user to assist the user in selecting a program for the INS. The programming device directs the INS to deliver neurostimulation therapy according to a plurality of programs during a programming session. Each of the programs includes parameters that define the neurostimulation delivered according to that program. For example, each program may include as parameters a voltage or current pulse amplitude, a pulse width, a pulse rate, and a duty cycle. The program may also identify as parameters the electrodes selected from a set coupled to the INS and their polarities, e.g., anode or cathode, for delivery of neurostimulation according to that program.
