Abstract: A subscriber unit of a time division multiple access (TDMA) radiotelephone system is, from a power consumption standpoint, reconfigured in each time slot of a TDMA frame to a power consumption tessellation in which subscriber unit circuit components not needed for communication signal processing in that time slot are powered down, and other components are powered up.

Abstract: A gas-fired cooking device includes a braising cavity defined on its lower side by a heated surface. A more uniform heating of the heated surface is provided by a plurality of heating chambers disposed below the heated surface, with each of the heating chambers heated by at least one naturally fed gas burner. A portion of the hot combustion gases rise into upper zones associated with each heating chamber that have relatively low average front-to-back air flow therein. The upper zones have sidewalls and downwardly extending dam walls that cooperate to create the low flow zones beneath the heated surface. The relatively low flow rates within the low flow zones allow a more uniform layer of hot combustion gases to be formed along the underside of the heated surface, thereby more evenly delivering heat to the heated surface. There may be two or more such heating chambers.

Abstract: A splashplate antenna system configured using hybrid mode-matching techniques has improved secondary beam characteristics, including improved sidelobe performance, improved electric and magnetic plane correlation, reduced cross-polarization, improved electric and magnetic plane phase center correlation, and improved overall matching between the waveguide and the splashplate (sub-reflector). Internally, the waveguide contains a wall constructed from a series of varying dimensioned cross-sections that cause signals introduced to radiate in a multiple mode, Gaussian-like field pattern. The Splashplate is configured so that the waves received from the waveguide maintain the circular pattern symmetry, as well as other characteristics.

Abstract: An interface is useful in browsing output vectors resulting from applying a transfer function to input data. The interface allows a user to explore effects of different parameter settings which make up the transfer function, particularly in connection with computer-generated and computer-modified images. The interface includes two portions, a central display panel and a surrounding area of a plurality of image displays. Thumbnail sketches of images corresponding to each of the output vectors are located in the central display panel to represent the relationships between the output vectors. The output vectors are processed to determine distances between them, and the distances are then projected to the two-dimensional display of the central display panel. The central display panel can be controlled to pan and zoom the display to review the thumbnail sketches. The user can then select different thumbnail sketches so that full-sized images are displayed in the plurality of image displays.

Abstract: A system for adjusting and dumping the position of a seat, such as a vehicle passenger or driver's seat, utilizes simultaneously translating master and slave adjustment rods to pivot the seat back frame about a pivot point. Each adjustment rod is locked in a passenger pre-set position by a corresponding locking mechanism. This preset position is “remembered” by way of a marker selectively engaged to the master adjustment rod, and is restored when the marker resides within a marker dock affixed to the locking mechanism. A user adjustment input is operable to release the two locking mechanisms and the marker from the corresponding rods so that the rods can freely translate as the passenger adjusts the angle of inclination of the seat back. When the adjustment input is released, the locking mechanisms and marker re-engage to provide the memory function for the system.

Abstract: A method for making a thin dielectric layer is disclosed which is useful in fabricating semiconductor devices, particularly transistors and DRAM cell devices. The method comprises a two-steps, i.e., (i) growing a base layer of dielectric material on a substrate having a thickness in excess of the desired thickness for the layer, and (ii) etching back the base layer to the desired thickness. With these two steps, a thin dielectric layer of less than 20 Å may be provided having substantial uniformity across its surface with a standard deviation in surface contours of less than 0.7 Å.

Abstract: A subscriber unit of a time division multiple access (TDMA) radiotelephone system is, from a power consumption standpoint, reconfigured in each time slot of a TDMA frame to a power consumption tessellation in which subscriber unit circuit components not needed for communication signal processing in that time slot are powered down, and other components are powered up. Some circuit components are powered down by switching their power supply circuits. In order to minimize the extent of circuitry that must be provided to distribute power consumption control signals, other techniques (which utilize circuitry provided for other purposes), such as clock frequency control or power down commands, also are utilized to modify controlled circuit component power consumption without actually controlling power supply circuits.

Abstract: Methods and apparatus are provided for accessing an experience journal which includes unstructured text items relating to a topic, such as a medical condition. The method is implemented in a computer system including a processor, a storage device, a video display unit having a display screen, and a user interface.

Abstract: A system for generating a set of graphical images based upon application of different graphical transfer functions to data of physical structures in a scene. The application of the different graphical transfer functions define graphical images of a single scene having different characteristics. A user can then review the images to select a desirable image, without having to define or know the graphical transfer function which generates the image. The system of the present invention generates a dispersed set of output vectors representing characteristics of the set of images based upon a transfer function. The system creates the dispersed set by generating a random set of output vectors and then randomly perturbing one. The perturbed vector replaces one of the other vectors if the replacement results in a more dispersed set. The process is repeated until a thoroughly dispersed set of output vectors has been obtained.

Abstract: A system generates and arranges animation sequences of articulated characs for review and selection by a user. Motion of articulated characters is based upon input parameters, such as torques at joints of the character. The system can be used to select appropriate parameters to obtain desirable motion of the articulated characters. The system generates a set of input vectors containing parameters of the motion. The input parameters are then processed to determine animation sequences and corresponding output vectors. The output vectors include characteristics of the motion. The input vectors are selected to provide a dispersed set of output vectors. A large number of random input vectors can be generated and then culled to leave a dispersed set of output vectors. Alternatively, a set of randomly generated input vectors of a predetermined size are randomly perturbed, to further disperse the output vectors.
