  • Patent number: 5734794
    Abstract: A computer based system utilizing cues extracted from audio speech to select from among a database of stored image cells to produce synthesized animated characters. A database of image cells is created by storing the face of an actor or other character articulating some 40 phoneme sounds, in 8 different emotions from 25 different camera angles. Audio speech is then analyzed and the faces are extracted based on phoneme sounds and emotion cues within the spectral information of the speech. The position of a user operated camera controller is polled to determine a desired camera angle and the three image parameters (articulation, emotion and camera angle) are used to select an image from the database associated with the phoneme. The selected images are interpolated to produce a smooth, life-like character or cartoon animation sequence, and then stored to a video recorder.

  • Patent number: 5692945
    Abstract: A toy is disclosed for producing a simulated eruption. The toy comprises a container having a first chamber for holding a predetermined quantity of a first reagent and a second chamber for holding a predetermined quantity of a second reagent. The second chamber communicates with an upstanding convergent nozzle terminating at its upper end in an orifice opening to the exterior of the container. When the sidewalls defining the first chamber are squeezed, a portion of the first reagent held therein is forced through a connecting tube into the second chamber, where the first regent reacts with the second reagent to produce gaseous products. The elevated pressure thereby created within the second chamber causes the reagent mixture to be ejected from the nozzle orifice at high velocity. The toy may additionally comprise a simulated volcano landscape having a eruption tube depending from the volcano crater which receives at its lower end the tip of the nozzle.

  • Patent number: 5675665
    Abstract: A bounds evaluation unit generates a bounds measurement pair corresponding to a character pattern pair determined from a handwritten word. Within the bounds measurement pair, a first bounds measurement corresponds to a first character pattern, and a second bounds measurement corresponds to a second character pattern. The first and second bounds measurements are each a bounding box that defines a left-most, a right-most, a top-most, and a bottom-most extent of the corresponding character pattern. The bounds measurement pair is compared against one or more bounds model pairs, where each bounds model pair corresponds to a hypothesized character identifier pair in which each individual hypothesized character identifier has been determined by a character recognition unit. Each bounds model pair indicates the expected size and position of a character pattern pair corresponding to the hypothesized character identifier pair.

  • Patent number: 5675270
    Abstract: A data line for an integrated circuit such as field programmable gate array, has a relatively fast rise time, consumes relatively low amount of current, and maintains a relatively fast fall time. A data conductor is connected to a circuit element providing a current path from the data conductor to a source of the supply voltage. A plurality of data-in drivers are connected to the data conductor which act in one state to pull the data conductor from the supply voltage to ground, and act in another state to present high impedance to the data conductor. A dynamic element is included, which connects an additional current path between the data line and the supply during transitions from ground to the supply, and which disconnects the additional current path otherwise. This speeds up the transitions from low to high, while not opposing the transitions from high to low.

  • Patent number: 5667559
    Abstract: An apparatus and method for removing volatile organic compounds from an air stream wherein airborne adsorbent material is mixed with contaminated exhaust air in a vertical main column. Volatile Organic Compounds (VOCs) within the exhaust air adhere to the adsorbent material and are thus removed from the air. The clean air exits the system and the saturated adsorbent material falls through the bottom of the main column and into a lower reservoir. The saturated adsorbent material is desorbed and recycled through the adsorber apparatus by being drawn up from the lower reservoir through a secondary column and deposited at the inlet to the main column. At the top end of the main column, the adsorbent material is once again dropped into the contaminated exhaust air flowing through the main column. This process is constant and adsorbent material is continuously being recycled through the system.

  • Patent number: 5666569
    Abstract: A fixed lens camera comprises a fixed focus lens, an infrared filter, and an optical low pass filter, all disposed in succession within a housing, coaxial with an optical axis. Light from a target passes through an aperture in the housing, and then through the lenses and filters. An image sensor receives the filtered light, and outputs a two-dimensional array signal of corresponding voltages proportional to the incident light striking each sensing element. The voltage signal from the image sensor is filtered using a high pass filter, and the high frequency components of the signal are measured to determine the relative focus of the light from the target. The signal measurement is displayed on a bar LCD to enable focusing of the lens by moving the camera along the optical axis while observing the LCD output.

  • Patent number: 5663076
    Abstract: Automated photolithography of integrated circuit wafers is enabled with a processor connected to a Rayleigh derator, a form factor generator, a logic synthesizer, a layout generator, a lithography module and a wafer process. The Rayleigh derator receives manufacturing information resulting from yield data in the wafer process, and this manufacturing data is then used to derate the theoretical minimum feature size available for etching wafer masks given a known light source and object lens numerical aperture. This minimum feature size is then used by a form factor generator in sizing transistors in a net list to their smallest manufacturable size. A logic synthesizer then converts the net list into a physical design using a layout generator combined with user defined constraints. This physical design is then used by the mask lithography module to generate wafer masks for use in the semiconductor manufacturing.

  • Patent number: 5659769
    Abstract: A computer operating system Text Services Manager (TSM) operates as an interface between an application and a selection of text services, enabling the user to efficiently select from among a variety of text services without regard to the specific protocol requirements of the application. The TSM architecture consists of an application program which receives user input through the input event manager of the operating system toolbox routine. The TSM receives the user input event and controls the transmission of the event to a component manager for redirection to a specific text services component, based on the instructions of the TSM. The text services component processes the input method and returns the processed input to the TSM, where the TSM directs the generation of an appropriate protocol for return of the processed input event to the application.
