摘要： An air filter assembly for removing particulate matter from an incoming dirty air stream. The assembly includes a housing having an inlet, an outlet, a dirty air chamber and a clean air chamber and a non-cylindrical shaped elongated filter element arranged within the dirty air chamber constructed to remove particulate matter from an incoming air stream. A plurality of non-cylindrical filter elements are preferred. The non-cylindrical filter elements provide a decreased incoming air stream velocity when compared to conventional cylindrical filter elements having the same surface area. Alternately, the non-cylindrical filter elements allow an increase in the volume of incoming air when compared to conventional cylindrical filter elements having the same surface area.

摘要： A solar energy collector apparatus and method, the apparatus including an open-top shell structure configured with either an enclosed or lattice configuration and having a Fresnel lens system covering the open top of the shell structure. A mirror system and solar energy absorber apparatus are placed inside the shell structure. The shell structure is mounted upon a hollow axle for rotation about its longitudinal axis. The shell structure is also mounted for vertical movement of one end of the longitudinal axis to adapt the shell structure for following north-south changes in the sun's seasonal position. The hollow axle supports the solar energy absorber apparatus nonrotatably inside the shell structure and in fluid communication with insulated heat transfer conduits that pass nonrotatably through the hollow axle. A photovoltaic apparatus may be included in the shell structure for converting at least a portion of the solar flux to electrical energy while the heat transfer conduits supply any necessary cooling to the photovoltaic apparatus. This combination of features provides higher solar efficiencies and higher temperatures in the heat transfer fluid. The method includes tracking the sun with the solar energy collector apparatus thereby maximizing the amount of solar energy collected while eliminating twisting and thereby coupling failures in the heat transfer conduits.

摘要： A solar energy collector apparatus and method, the apparatus including an open-top shell-like structure with a reflective optical system in the shell structure for directing solar energy toward a solar energy absorber apparatus inside the shell structure. The shell structure is mounted upon a hollow axle for rotation about its longitudinal axis and may be mounted for vertical movement to follow north-south changes in the apparent seasonal position of the sun. The solar energy absorber apparatus is nonrotatably mounted inside the shell structure in fluid communication with heat transfer conduits that pass through the hollow axle thereby avoiding rotatable couplings in the conduits. Photovoltaic apparatus for converting at least a portion of the solar spectrum to electrical energy may also be included in the shell structure. This combination of features provides higher solar efficiencies and higher temperatures in the heat transfer fluid. The method includes tracking the sun with the solar energy collector apparatus thereby maximizing the amount of solar energy collected while eliminating coupling failures in the heat transfer conduits.

摘要： A ring of transmitter and receiver transducer arrays circumbscribes an object to be scanned. Semicircular wave fronts of ultrasound energy are propagated from different points around the ring of transducers by triggering the transmitter arrays in sequence. The reflected and transmitted ultrasound energy picked up by the receiver arrays is then electronically analyzed and a synthetically focused image corresponding to the scanned object is reconstructed on a display screen. Surprisingly high quality resolution for the reconstructed images is achieved by carefully controlling the type of waveform from which the displayed image is reconstructed. In one embodiment of the invention, the signals received by the receiver arrays are processed by a waveshaping circuit to achieve the desired waveform. In a second embodiment of the invention, the desired waveform is generated by a waveform generator circuit and transmitted by the transmitter arrays. The quality of resolution for the reconstructed image of reflection is further improved by obtaining, through a computer aided ray tracing technique, the connecting rays between each point in the object and each transmitter and receiver array element. Data sampling times for each point in the reconstructed image are then corrected for refraction by computer aided integration of the object's refractive index along each connecting ray. Correction of the sampled data for amplitude attenuation is similarly obtained by computer aided integration of the object's linear attenuation coefficient along the connecting rays.

摘要： A noise suppression device receives data representative of a noise-corrupted signal which contains a speech signal and a noise signal, divides the received data into data frames, and then passes the data frames through a pre-filter to remove a dc-component and the minimum phase aspect of the noise-corrupted signal. The noise suppression device appends adjacent data frames to eliminate boundary discontinuities, and applies fast Fourier transform to the appended data frames. A voice activity detector of the noise suppression device determines if the noise-corrupted signal contains the speech signal based on components in the time domain and the frequency domain. A smoothed Wiener filter of the noise suppression device filters the data frames in the frequency domain using different sizes of a window based on the existence of the speech signal. Filter coefficients used for Wiener filter are smoothed before filtering. The noise suppression device modifies magnitude of the time domain data based on the voicing information outputted from the voice activity detector.

摘要： The intelligent data storage manager functions to combine the non-homogeneous physical devices contained in a data storage subsystem to create a logical device with new and unique quality of service characteristics that satisfy the criteria for the policies appropriate for the present data object. In particular, if there is presently no logical device that is appropriate for use in storing the present data object, the intelligent data storage manager defines a new logical device using existing physical and/or logical device definitions as component building blocks to provide the appropriate characteristics to satisfy the policy requirements. The intelligent data storage manager uses weighted values that are assigned to each of the presently defined logical devices to produce a best fit solution to the requested policies in an n-dimensional best fit matching algorithm. The resulting logical device definition is then implemented by dynamically interconnecting the logical devices that were used as the components of the newly defined logical device to store the data object.

摘要： A solar energy collector apparatus and method, the apparatus including an open-top shell-like structure. A Fresnel lens system and a mirror system inside the shell structure focus and direct solar energy toward a solar energy absorber apparatus also inside the shell structure. The shell structure is mounted upon a hollow axle in a framework for rotation about its longitudinal axis. The framework supports the longitudinal axis in a position generally parallel to the axis of rotation of the earth to provide an equatorial mounting for the solar energy collector. Rotation about the longitudinal axis adapts the solar collector for following the east-west movement of the sun. The optical apparatus in the shell structure is adapted for movement to follow the north-south seasonal changes in the sun's position. The solar energy absorber apparatus is nonrotatably supported inside the shell structure by the hollow axle and heat transfer conduits pass through the hollow axle to the solar energy absorber apparatus in nonrotable relationship therewith. A photovoltaic apparatus may be included within the shell structure for converting at least a portion of the incoming solar spectrum to electrical energy. This combination of features provides higher solar efficiencies and higher temperatures in the heat transfer fluid. The method includes tracking the sun with the solar energy collector apparatus thereby maximizing the amount of solar energy collected while eliminating coupling failures in the heat transfer conduits.

摘要： A heat storage apparatus and method including a heat storage medium encapsulated within a container and heat exchange apparatus for exchanging thermal energy with the heat storage medium. The heat storage medium may include a salt having a relatively high latent heat of reaction at a relatively low temperature range. The dehydration reaction of sodium sulfate decahydrate appears to the most promising reaction for this application. Other suitable salts and salt mixtures for other temperature ranges may also be used. The apparatus includes, where necessary, techniques for stirring the heat storage medium to inhibit stratification of the salt during cycles of dissolution and recrystallization or fusion.
