  • Patent number: 7246014
    Abstract: An Enterprise Energy Management (“EEM”) software system is disclosed that displays EEM data and allows a user to interact with the data to better understand and manage their electrical system. The EEM software system collects real-time, near real-time and historical input data from various data sources, creates useful information from that data by filtering and isolating relevant data and performing analytics on the data, displays that data to the user in an easy to understand format, and allows the user to interact with the displayed data. The EEM software allows the user to perform what-if analysis, make changes in their system and verify results of those changes. The graphical user interfaces provide context sensitive and relevant guidance to novice and expert users.

  • Patent number: 6959456
    Abstract: A protection suit, particularly a spacesuit, has an opening in a back portion of the spacesuit for entering and exiting the suit. The spacesuit is suspended on one side of a bulkhead (5?) so that a hole in the bulkhead is aligned with the opening in the back portion of the suit. The opening is closeable by a backpack (3) which fits through the hole in the bulkhead into a decontamination chamber (7) on the opposite side of the bulkhead. Two sealing and interlocking systems are used. Each system has two subsystems to provide a total of four sealing and interlocking subsystems. A first subsystem (4) connects the spacesuit to the bulkhead that separates a living and working space from an airlock. A second subsystem (6) connects a backpack to the spacesuit (1). A third subsystem (9) connects the spacesuit, preferably through the backpack (3), to a decontamination chamber (7). A fourth subsystem (12) connects the decontamination chamber to the bulkhead (5?).

  • Patent number: 6743019
    Abstract: A test chamber is pivotably suspended in an aircraft, so that the center of gravity of the test chamber always self-actingly orients itself in the direction of the effective residual acceleration. To simulate a selected acceleration greater than 0 g and less than 1 g, the aircraft is flown along a parabolic flight path with a downward vertical acceleration such that the difference between Earth's gravitational acceleration and the aircraft's acceleration corresponds to the selected acceleration to be simulated. To simulate gravitational conditions on Mars, the aircraft is flown with a downward vertical acceleration of about ⅔ g, so that the residual acceleration acting on the test chamber is about ⅓ g. The atmospheric conditions, such as the gas composition, pressure and temperature, of Mars can also be established in the test chamber.

    Abstract: A protection suit, particularly a spacesuit, has an opening in a back portion of the spacesuit for entering and exiting the suit. The spacesuit is suspended on one side of a bulkhead (5′) so that a hole in the bulkhead is aligned with the opening in the back portion of the suit. The opening is closeable by a backpack (3) which fits through the hole in the bulkhead into a decontamination chamber (7) on the opposite side of the bulkhead.

  • Patent number: 5593110
    Abstract: The arrangement serves to control the structural dynamic response characteristic of a booster rocket, which is provided with a propulsion engine as well as a payload. The booster rocket includes at least one control unit as well as at least one control element for altering a flight path perpendicularly to a lengthwise axis of the rocket. The control element is embodied as a rotatably supported control fin, arranged at a lateral side area of the booster rocket. Sensors are provided to measure lateral wind loads. An adjustment element is connected to the control fin and is adjusted by the control unit in such a manner that measured values provided by the wind sensors are converted into position adjustments of the control fin for compensating crosswise forces.

  • Patent number: 5036216
    Abstract: A video dot clock generator includes a phase-locked loop (PLL) which includes a voltage controlled oscillator, a frequency divider, a phase comparator and a loop filter. The voltage controlled oscillator (VCO) is programmable to provide multiple frequency ranges for a given range of control voltages applied to the oscillator. The programming affects both the frequency range and the gain of the VCO. The phase comparator includes circuitry which simulates a predetermined minimum phase error which, when compensated for, substantially eliminates jitter in the dot clock signal. The frequency divider used in the PLL and a similar frequency divided used to generate the reference signals for the phase comparator are programmable via an internal memory which also holds programmable control signals for the VCO. The memory, in turn, may be programmed by the user to achieve desired frequency and loop again characteristics for a given application.

  • Patent number: 4590393
    Abstract: A novel high speed gallium arsenide depletion mode field effect transistor logic circuit is provided. One logic input is connected to the source electrode of the switching transistor and draws current when a low level input voltage is provided. Other logic inputs are connected to the gate electrode of the switching transistor and supplies current when a high or low level input voltage is provided. The novel logic output from the source electrode of the switching transistor is a complex OR function which may be employed for a logic family having fewer stages of logic than prior art gallium arsenide circuits.

  • Patent number: 4496856
    Abstract: An improved high speed gallium arsenide (GaAs) to emitter coupled logic (ECL) voltage level converter is provided which consumes less power and also provides an improved speed-power product performance characteristic. The converter includes a three branch output circuit which emulates the operation of an ECL output driver. The emulator circuit causes faster switching by compensating for parasitic resistances and capacitance and is also provided with a gate discharge network which reduces switching time of the ECL output emulator.

  • Patent number: 4494016
    Abstract: A gallium arsenide buffer amplifier for use in a very large scale integrated circuits is provided. The transistor device in the buffer amplifier has a uniform depth N+ source, gate and drain region and the N+ dopant concentration is made very high which effectively reduces the resistance of the transistor device and permits the area of the device to be reduced by more than one order of magnitude while maintaining high current and power levels.

  • Patent number: 4404480
    Abstract: The present invention provides a high-speed low-power gallium arsenide basic logic circuit which is capable of being driven by either emitter coupled logic or gallium arsenide logic level signals to provide combinational logic gating such as OR-AND, OR-NAND, OR-AND-OR and OR-AND-NOR capable of driving directly either emitter coupled logic or gallium arsenide logic circuits. The combinational logic gating is basically accomplished by diode logic which performs other functions and which requires less area on an integrated circuit chip than active switching transistors.

  • Patent number: 4393315
    Abstract: This invention provides a novel high-gain stabilized converter circuit which is adapted to convert emitter coupled logic (ECL) signals for use in gallium arsenide (Ga As) circuits. The novel converter is adapted to be made in gallium arsenide logic on the same chip as the logic circuitry which it is driving. The converter includes a novel differential amplifier having a level shifting network at the active input and a second level shifting network at the reference input to provide a stabilized high-gain circuit which is compensated for variations in temperature and process deviations.

  • Patent number: 4280212
    Abstract: A CMOS timing device having a primary oscillatory reference source, a chain of series connected bistable divider stages whose data outputs are applied to a decoder/display by way of a multiplexing network. The multiplexing network is comprised of a plurality of multiplex sections, each section having a plurality of data transmission channels or paths. Each channel includes a plurality of MOS devices of a first type connected to a common bus. All channels driving the common bus share a single MOS device of a second type which provides a complementary function with respect to the first type to establish predetermined operating voltage levels for the data logic states carried by the common bus. The data on the common bus of each multiplex section is stored in a CMOS bistable latching type flip-flop whose regenerative feedback path is MOS device controlled.
