A method for treating the lung during an acute episode of reversible chronic obstructive pulmonary disease such as an asthma attack. The method comprises transferring energy to an airway wall of an airway such that a diameter of the airway is increased. The energy may be transferred to the airway wall prior to, during or after an asthma attack. The energy may be transferred in an amount sufficient to temporarily or permanently increase the diameter of the airway. The method may be performed while the airway is open, closed or partially closed.

By the technology, the purposes for accurate located perforating of oil sheets and pumping after perforating are achieved, oil layers are protected effectively, well control safety in construction is improved, and technical support is provided for well-killing-free production of high-pressure oil wells and high-gas-oil-ratio oil wells.

To provide a remote control system which is operable by using a portable terminal only when a person is present near a vehicle.The remote control system is formed of a receiving means for receiving a door locking request signal or a door unlocking request signal, a door locking mechanism, a signal determining means for determining whether a signal received by the receiving means is the door locking request signal or the door unlocking request signal, a locking instructing means for transmitting a locking instruction signal to the locking mechanism, an unlocking instructing means for transmitting an unlocking instruction signal to the locking mechanism, and a person checking means for checking whether or not a person is present near the vehicle, and transmitting a person confirmation signal to the unlocking instructing means. If the signal determining means determines that the signal received by the receiving means is the door locking request signal, the locking instructing means transmits the locking instruction signal to the locking mechanism. If the signal determining means determines that the signal received by the receiving means is the door unlocking request signal, the unlocking instructing means transmits the unlocking instruction signal to the locking mechanism on condition that the locking mechanism receives the person confirmation signal in a predetermined time period.

A concrete finishing apparatus and method for smoothing and flattening partially set-up concrete to a close-tolerance surface includes a movable unit that is movable and supported at a partially set-up concrete surface and at least one rotatable ring finishing member mounted to the movable unit. The rotatable ring finishing member is positioned at the concrete surface and rotatable to engage and finish the surface of the partially set-up concrete to a higher quality, closer-tolerance flat and level concrete floor surface. The apparatus may include a pair of rotatable ring finishing members that may be rotatable in opposite directions to enhance the floating and finishing processes and to transport any cement paste, sand, small aggregate, or concrete mix residue forward with the rotatable ring finishing members working surfaces to cut high areas and fill in any low areas as the concrete finishing apparatus moves over the partially set-up concrete.

A scanning-type image display devices includes: a light source; a scanning unit that scans light beams emitted from light source to display an image on a projection plane; and a control unit that controls the emission time of the light beam from the light source for each pixel of the image, and that also controls the emission time for each pixel depending on the scanning angle of the scanning unit.

A device for manufacturing a frusto-conical shaped meat product by means of a mold casing that receives ground meat under pressure. The mold casing has an inner wall, a first lateral end, and a second lateral end. The mold casing has a frusto-conical shape, for forming the meat product into a desired shape and cross section. An end fitting is secured to the discharge end of a meat stuffer. The end fitting includes a plurality of pivotable, flexible, adjacent, partially overlapping fins. The fins pivot as they are moved relative to the mold casing, and in that way maintain contact with the inner wall of the mold casing.

A treat dispensing pet toy comprises a hub assembly having first and second hubs and an axle interconnecting the hubs. A barrel is mounted over the axle and is disposed between the hubs. The barrel has an interior chamber to hold treats. A treat dispensing opening is formed on the barrel and communicates with the interior chamber. When the pet toy is contacted with sufficient force, the hub assembly and barrel independently rotate thereby establishing a rotational differential. Treats fall through or are otherwise ejected from the opening in the barrel. According to a method of dispensing treats, the barrel and hub assembly independently rotate at different rotational speeds to affect the rate of dispensing treats.
