A stress management device is formed in an integrated design that enables pulse measurement, display of results and a power supply gathered into a small finger clip device. The stress management device includes a non-invasive infrared sensor that identifies and measures pulse rate variability and utilizes that information to calculate the power spectrum distribution and create a curve of the results multiple times per second. The device incorporates a display screen on which a graphic image of a pair of lungs filling and emptying to encourage the user into a predetermined breathing pattern known to reduce stress levels during a training period. After the completion of the training period, the device presents a score reflecting the percentage of times the user achieved high, medium and low relaxation states, and a pie chart reflecting the distribution of the states of relaxation calculated during the training period.

A fuel injection apparatus has a pressure booster located between a high-pressure reservoir and a nozzle chamber. A high-pressure chamber of this fuel injection apparatus communicates with the pressure line with a control chamber which actuates an injection valve member of a fuel injector and with the nozzle chamber. A compensation device is connected to a high-pressure line between the high-pressure reservoir and the fuel injector produces a throttled connection or an unthrottled connection between the high-pressure reservoir and the fuel injector.

A downhole tool, adapted to retain a shaped charge surrounded by a superatmospherically pressurized light gas, is employed in a method for perforating a casing and penetrating reservoir rock around a wellbore. Penetration of a shaped charge jet can be enhanced by at least 40% by imploding a liner in the high pressure, light gas atmosphere. The gas pressure helps confine the jet on the axis of penetration in the latter stages of formation. The light gas, such as helium or hydrogen, is employed to keep the gas density low enough so as not to inhibit liner collapse.

A hydraulic unit, in particular for lifting and lowering loads in stacking trucks, has at least one working cylinder (10). The piston/rod unit (12) of the cylinder is guided movably in a housing (22). By a hydraulic pump (25), the piston/rod unit can be extended in its one drive direction (30) and can be retracted in its other opposite drive direction (32). A control device (20) actuates the displacement movements to that effect. A storage device (38) is fed energy in one drive direction (32). The energy fed in can be called up from the storage device (38) to assist a displacement movement in an opposite drive direction (30).

A method of sealing annular space between an upright outer tube and an upright inner tube extending within the outer tube along an axial direction thereof involves pouring a liquid seal material into the annular space onto a support member fitted within the annular space between the outer tube and the inner tube in a manner substantially closing around the inner tube. The liquid seal material is poured in an amount sufficient to fill radial space between the inner tube and the outer tube fully around the inner tube, the liquid seal material is then cured to form an annular seal between the inner tube and the outer tube. The method is useful in sealing of the annular spacing between the surface and production casing of a gas well and installing a venting system to facilitate controlled venting of the annular space.
