  • Patent number: 7739905
    Abstract: A method of estimating the height of water (hw) that is present on a wet ground of a road and that is in contact with a tread of a tire of a vehicle travelling on this wet road utilizes one or more sensors in the tread of the tire. Each of the one or more sensors is capable of measuring a characteristic quantity of stresses that the tread experiences locally when the tire is rolling on the ground. A signal corresponding to these measurements is produced, and a portion of this signal relating to a passing of the one or more sensors into an apparent area of contact between the tire and the ground is extracted. An instantaneous value (?L), relating to a length of an indirect contact region of the apparent area of contact between the tread of the tire and the ground, is determined from this information, and a water height (hw) is estimated from a calculation that takes into account the determined instantaneous value.

  • Patent number: 7739910
    Abstract: A system, and method for isometric exercise that safely reduces resting blood pressure and increases overall cardiovascular health. An apparatus includes a handle or grip configured to provide natural resistance to force and maximize user comfort and the system includes squeezing the handle or grip of the apparatus with a force that is less than the maximum squeeze force of the user, thereby reducing blood flow through contracting arm muscles and safely increasing blood pressure during exercise. Resting blood pressure is reduced through regular use of the system. The method includes measuring and recording the maximum squeeze force of a user, calculating a fractional force using the duration of exercise or a desired fractional force percentage, and alternately inducing the user to apply the fractional force for a calculated time and inducing the user to apply a lesser fractional force or no force for a calculated time.

  • Patent number: 7739911
    Abstract: Using an ultrasonic field, properties of a solid liquid suspension such as through-transmission attenuation, backscattering, and diffuse field are measured. These properties are converted to quantities indicating the strength of different loss mechanisms (such as absorption, single scattering and multiple scattering) among particles in the suspension. Such separation of the loss mechanisms can allow for direct comparison of the attenuating effects of the mechanisms. These comparisons can also indicate a model most likely to accurately characterize the suspension and can aid in determination of properties such as particle size, concentration, and density of the suspension.

  • Patent number: 7739937
    Abstract: A band saw blade guide includes a cylindrical chisel shaped member mounted at an oblique angle to a band saw blade. The blade guide adjusts the angle of the band saw blade by rotation of the guide about its axis. By rotating the guide about its axis, the angle of the chisel point guiding surface is changed thereby changing the angle of the blade. Further the blade may be guided by a single guide forced against one surface of the blade thereby eliminating the need for guides on both sides of the blade.

  • Patent number: 7739938
    Abstract: The launching of an unmanned projectile includes pre-packaging a barrel with a projectile, a pusher cup, and a gas generator. The gas generator generates gas to propel the projectile out of the barrel. A pressure chamber increases a pressure of the gas in the barrel. The pressure chamber comprises a front body portion connected to the gas generator; an aft body portion connected to the front body portion and the gas generator; and a vent sleeve positioned around the front body portion and adapted to provide an aperture through which the gas exits the barrel in order to control a level of gas pressure in the barrel. A triggering of the gas generator causes the pusher cup to push the projectile out of the barrel at a predetermined launch velocity in order to attain a predetermined self-propelled flight trajectory, wherein the triggering causes the pusher cup to exit the barrel.

  • Patent number: 7739940
    Abstract: In a directional control valve device, a first passage connects a second port with a first port by using a part of a movement path of a moving valve element when the moving valve element is in a position of a first end. A second passage connects the second port with the third port by using an internal passage of the moving valve element when the moving valve element is in a second end. The moving valve element is provided with a first check valve for permitting a flow in the internal passage only in the direction from the third port to the second port. When a fluid pressure is applied to the third port, the fluid pressure presses the moving valve element toward the second end so that the first passage is closed, and the first check valve is opened to open the second passage.

  • Patent number: 7739941
    Abstract: A hydraulic drive system comprises a hydraulic actuator comprising a piston reciprocable between two cylinder heads for actuating a machine. A flow switching device reverses the direction of hydraulic fluid flow to and from chambers on opposite sides of the piston. The piston stops at the end of each piston stroke when a shuttle valve associated with the piston opens to allow hydraulic fluid to flow between the chambers cancelling the differential pressure that acts on the piston to cause reciprocal movement. A controller is programmed to determine when the piston reaches the end of each stroke based upon at least one of hydraulic pump speed, hydraulic fluid pressure, or elapsed time, with each of these measured during each stroke. The controller then sends an electronic signal to command the flow switching device to reverse the direction of hydraulic fluid flow.

  • Patent number: 7739942
    Abstract: A vehicular hydraulic system with a pump and first and second hydraulic applications arranged in series. The fluid upstream of the first application may be elevated to a first threshold pressure value. A pressure-dump valve is disposed downstream of the first application and fluid entering the valve flows through an inlet port, primary flow channel and outlet port of the valve to the second hydraulic application. The valve includes a valve member that axially slides within an elongate valve chamber, partitioning the primary flow channel from a low pressure volume. The valve also includes a low pressure port and a bypass port that diverts fluid past the second application. The valve member is biased into a position wherein fluid is diverted through the bypass port when the pressure in the primary flow channel exceeds a second threshold value. The first threshold value is greater than the second threshold value.

  • Patent number: 7739943
    Abstract: A vehicular hydraulic system having a pump, first application, pressure-dump valve and second application arranged in series. The pressure-dump valve diverts a portion of the primary fluid flow past the second application when the pressure exceeds a threshold value. A valve member in the pressure-dump valve defines a pressure-reducing orifice that communicates fluid across the valve member. A check valve prevents flow through the pressure-reducing orifice when the pressure in the valve is below the threshold value. When the pressure exceeds the threshold value, fluid flows through check valve and the pressure reducing orifice resulting in the movement of the valve member and exposure of a bypass port thereby diverting a portion of the primary fluid flow past the second application. The check valve may be selectively variable to provide for the adjustment of the threshold value. A priority valve may also be provided upstream of the first application.
