Snowmobile drive track
US Patent 7,712,846
May 11, 2010
An endless drive track for a snowmobile is provided with traction lugs that are inclined relative to normal to the track base. When the traction lugs are inclined away from the direction of travel for the track, the traction lugs can compress the snow before engaging the snow for traction, thereby providing lift for a snowmobile traveling in deep snow. Second traction lugs, angled opposite the first, provide hard snow traction and long traction life.
Vehicle seat comprising a height-adjustable seat frame
US Patent 7,712,836
May 11, 2010
A vehicle seat includes a height-adjustable seat frame which has at least two seat frame parts which can be moved relative to one another and at least one gas spring arranged between the seat frame parts for height adjustment purposes. The seat includes a control device that acts upon the gas spring and includes a valve device attached to a first seat frame part and has control valves for actuating gas flows for the gas spring. A control link on a second frame part actuates the control valves, so that a predefinable height of the vehicle seat is ensured regardless of a weight load on the vehicle seat. Movement of the control link relative to the second seat frame part brings about a height adjustment of the vehicle seat.
Floating drive on boat docking apparatus
US Patent 7,712,425
May 11, 2010
An improved floating boat lift incorporates a passive hydraulic pivoting lift mechanism, onto which a boat can be driven and positioned ready for storage using only the motive power of the boat itself. The passive hydraulic pivoting lift mechanism provides mechanical advantage in the pivoting action of the apparatus by way of passive hydraulic action, while at the same time dampening pivoting of the apparatus. Embodiments further allow for adjusting the elevation of the pivot point relative to the surface of the body of water by way of adjusting the buoyancy of the pivoting lift mechanism.
Business method for integrating and aligning product development and brand strategy
US Patent 7,711,596
May 4, 2010
A business method that improves brand identity by effectively allocating product development resources and prioritizing projects based on a systematic approach of defining assumptions that drive brand development and assessing a product development portfolio thereon.
High-side current sense hysteretic LED controller
US Patent 7,705,547
April 27, 2010
Systems and methods for hysteretically controlling Light Emitting Diodes (LEDs) when the input voltage is greater than or equal to 18 volts. An example system includes one or more LEDs and a circuit electrically coupled to the one or more LEDs. The circuit hysteretically controls an input voltage supplied to the one or more LEDs based on a sensed electric current that passes through the LEDs. The circuit includes a MOSFET switch for switching on and off the input voltage supplied to the one or more LEDs, a current sensing subcircuit including a first integrated circuit (IC) for sensing the current flowing through the one or more LEDs, a hysteretic comparator circuit including a second IC for generating a hysteretic control signal based on the sensed current, and a switch driver including a third IC for controlling operation of the switch based on the generated hysteretic control signal.
Antenna system for a micro air vehicle
US Patent 7,701,384
April 20, 2010
An antenna for a micro air vehicle (MAV) takes the form of a wrap-around antenna (e.g., wrapped around a portion of the MAV) that selectively emits radio signals in different directions depending on a frequency selected by a radio altimeter in the MAV. The radar altimeter may be a pulsed or a frequency modulated continuous wave (FMCW) radar altimeter. The wrap-around antenna includes groups of radiating elements in which at least each group includes an average height that is different from an average height of an adjacent group. Further, the average height of the group determines which group will emit the signals most efficiently so that a desired sector of space may be covered by the signals emitted from the antenna. In one example, the center frequency of the radar altimeter may be controlled in a deterministic manner to cause the radiating elements to successively cover desired sectors of space.
Aviator emergency oxygen system
US Patent 7,698,766
April 20, 2010
A method and apparatus for facilitating spinal alignment is disclosed. The contoured sleep system facilitates alignment of a person’s spine along the Sagittal plane when laying in a sleep-on-side position. An exemplary contoured sleep system has a trunk rest having a trunk rest surface and a trunk rest face.
Ground operations and imminent landing runway selection
US Patent 7,702,461
April 20, 2010
A method and system for locating aircraft with respect to airport runways and taxiways, generating and annunciating situational awareness advisories as a function of aircraft state parameters relative to a determination of the aircraft location.
User interactive exercise system
US Patent 7,695,406
April 13, 2010
System and method for interactive video game fitness equipment. Fitness hardware (e.g., an exercise bicycle, a stair machine, treadmill, elliptical trainer, rotary climbing wall, or other fitness equipment) interacts with a video game, optionally via various devices, e.g., a PC, gaming console, or other hardware and/or software device or system capable of implementing an interactive application), for an immersive hybrid exercise/game user experience.
Aviator emergency oxygen system
US Patent 7,694,680
April 13, 2010
A method, a system, and an oxygen delivery boomlet are configured to provide an additional partial pressure of oxygen to an aviator. The boomlet includes a conduit configured to receive an oxygen flow from a positive pressure oxygen source. A nozzle is in communicative connection with the conduit such that the oxygen flow the conduit receives is conducted to the nozzle. The nozzle is configured to direct the conducted flow of oxygen to an interpalatine region of the aviator. The boomlet is configured for attachment to a microphone boom.
