摘要： The present invention is an apparatus that can be operated by one person to move an article such as a pool table, vending machine, and the like, from place to place over a floor surface. The apparatus is made of a planar base and planar platform with a structure for slidably moving the apparatus across the floor. The apparatus includes a mechanism for pivotally connecting the base and platform attached at opposing sides of the apparatus. The pivotal connecting mechanism is operable to raise and lower the platform relative the base to selectively move the apparatus between a retracted position and an elevated position. The invention further provides a method of moving an article using the apparatus. In use, an operator positions the apparatus in the retracted position underneath the article and pushes downward on the handle of the movement actuating structure to elevate the platform which then contacts the article and raises it off the floor. The article is then moved to a new location, and the platform lowered to place the article onto the floor.

摘要： A pool table ball controller is programmable to vary time, cost, and other parameters relating to money-operated pool tables. A piano-hinge-type guard retains the balls and is operated by an electric motor driving a linkage to raise and lower the guard. Since the electric motor can be stopped in the lowered position, timed pool play can be selected so that the balls will continue to return to the user rather than being retained. The controller can be used to select between timed and rack play for a user of the pool table or may be moved into a programming mode wherein operators of the table can set time parameters relating to length of time for timed play and costs for both timed and rack play. In addition, diagnostic and other messages are displayed on an LCD screen. The controller also allows for programming in periods of time wherein cost and time are varied and when limits may be placed on time play and also periods when either timed or rack play are prohibited.

摘要： A single beam interferometer (10) comprises an intensity modulated laser beam (16) having a focus area for heating a test area (18) on the surface of a sample (12) producing a thermal bump (20). An unfocused probe laser beam (30) is directed toward the solid at an angle and has a beam area greater than the focus area of the heating beam (16). The sample (12) has a reflective surface for reflecting the probe beam (30). The reflected beam (31) comprises an AC beam portion (32) refracted by the thermal bump (20) and a DC beam portion (34) reflected off the unheated surface of the sample (12). The interference pattern (36) produced by the reflected beam (31) is detected and processed to obtain optical, elastic and thermal parameters of the sample (12).

摘要： The assembly (10) is a real-time imaging device for detecting radiation from an object field which is periodic in time. A video camera (14) detects emitted and reflected radiation from the object field (12) and produces a video signal comprising a series of pixels representing a frame of the image. The video signal is digitized (18) and received by a processor (16). The processor (16) averages the successive frames as in-phase images and quadrature images based on the periodicity of the object field to eliminate unsynchronous noise from the image and to display an image synchronous with the periodicity.

摘要： A defect detection system for thermally imaging a structure that has been energized by a sound energy. The system includes a transducer that couples a sound signal into the structure, where the sound signal causes defects in the structure to heat up. In one embodiment, a non-linear coupling material is positioned between the transducer and the structure to couple the sound energy from the transducer to the structure. A predetermined force is applied to the transducer and a pulse duration and a pulse frequency of the sound signal are selected so that the sound energy induces acoustic chaos in the structure, thus generating increased thermal energy. A thermal imaging camera images the structure when it is heated by the sound signal.

摘要： A system for the thermal imaging of sonically or ultrasonically excited subsurface defects in a structure. The system includes a hand-held sound source, a thermal imaging camera and a control unit. The sound source emits pulses of sound energy into the structure, and the camera generates images of defects in the structure that are heated by the sound energy. The control unit controls the operation of the sound source on the camera for timing purposes. The sound source includes a transducer that is positioned against the structure at a desirable location. The source further includes a pair of legs that are also positioned against the structure to define a plane in combination with the transducer. The length of each leg is adjustable relative to the length of the transducer so that the gun can be used against irregular surfaces. The legs include a rubber tip to further prevent the transducer from slipping on the structure. In an alternate embodiment, the gun includes three transducers that define a plane and act to stabilize the gun against movement.

摘要： A thermal imaging system for detecting cracks in a tooth. An ultrasonic dental cleaning tool is used to transmit ultrasonic energy through a jet of water to the tooth that causes cracks in the tooth to heat up. A thermal camera is used to detect the thermal radiation emitted by the heated cracks. The ultrasonic energy is in the form of a pulse where the frequency of the ultrasonic signal is substantially constant within the pulse. The control unit is employed to provide timing and control of the operation of the dental cleaning tool and the camera.
