Abstract: A thermoformed plastic container (10) is disclosed including a sidewall (18) formed by the intersection of three portions (20, 22, 24) formed by curved planar surfaces. The bottom portion (20) is generally frustoconical in shape having cross sections corresponding to the periphery of the bottom (16) and of an increasing size linearly dependent on increased spacing from the bottom (16). The upper portion (24) is generally frustoconical in shape having oval cross sections and of a decreasing size linearly dependent on increased spacing from the flange (12). The middle portion (22) is generally frustoconical in shape having oval cross sections different from that of the bottom and upper portions (20, 24) and of an increasing size linearly dependent on increased spacing from the bottom (16). The portions (20, 22, 24) intersect at curved intersection lines (26, 32) having varying spacing from the bottom (16). The bottom portion (20) creates a chamfered edge which is larger at the longitudinal front and back of the container (10) and which is narrower at the lateral sides of the container (10). The use of curved planar surfaces in creating the sidewall (18) is advantageous in allowing computer analysis in easily and quickly fabricating prototypes for evaluation.

Title: Marking of mold inserts to produce marked contact lenses
Inventor: WILLIAMS WAYNER E
IPC: B29C33/76
Filed: 1996-09-26
Granted: 2006-12-12
Abstract: A method for producing visible marks in molded contact lenses, particularly soft hydrogel contact lenses, by placing a recessed mark configuration in a metal insert. The metal insert is subsequently used to produce injection molding frames, which are then subsequently used in the molding of the final contact lenses. The recessed mark configuration is at lest approximately 10 microns deep, has a Volume Index, which is the ratio of the quantity volume below a reference surface minus the volume above the reference surface over the volume below the reference surface, of at least approximately 0.9. The recessed mark configuration also preferably has a ratio of surface roughness (RMS or Ra) to a peak-to-valley (PV) measurement, RMS/PV or of Ra/PV, of greater than approximately 0.15. The recessed mark configuration in the metal insert is subsequently transferred as a raised portion to the injection molded frames, and is then subsequently transferred as a visible recessed mark in contact lenses molded in the frames prepared using the inserts. The ratio of the surface roughness (RMS or Ra) to the height (H), wherein H is the distance between two reference lines in a profile of the mark, RMS/H or Ra/H, is at least approximately 1.5. A preferred method of imparting the recessed configuration to the insert is by Electric Discharge Machining (EDM). The dimensions of the several parameters can be verified by using a noncontact scanning white light interferometer.

Title: Method and apparatus of facial image conversion by interpolation/extrapolation for plurality of facial expression components representing facial image information
Inventor: ODA MASAOMI
IPC: G06T13/00
Filed: 1997-08-28
Granted: 2002-01-15
Abstract: An input/output control mechanism receives facial image information of different facial expressions of a plurality of human beings to provide control so that a normalization processing mechanism normalizes each facial image information.  A facial expression generation mechanism converts the normalized facial image information into facial expression components, and averages the facial expression components for each facial expression to store the same as average facial expression components.  The input/output control mechanism has the facial expression component converted by the facial expression generation mechanism after the applied facial image information is normalized.  The facial expression generation mechanism converts the facial expression components of the applied facial image information according to a difference between an average facial expression component corresponding to a facial expression of applied facial image information and an average facial expression component of a specified facial expression.  Synthesized facial image information is generated from the converted synthesized facial expression component.

Abstract: A high voltage power supply (40) having a plurality of high voltage generators (50a, 50b,... 50j) that produce a controlled current in a load (24) having a capacitive component. Each high voltage generator consists of a pulsewidth-modulated (PWM) inverter, a high voltage transformer, and a high voltage full bridge rectifier. The high voltage generators are divided into three groups:  Group I, Group II, and Group III. During a driving mode of power supply operation, the Group I, Group II, and Group III high voltage generators produce an output voltage (Vgen) from the power supply which exceeds a voltage (Vc) across the capacitive component of the load, causing the current in the load to increase. When the current in the load reaches a desired value, the power supply enters a tracking mode of operation. During the tracking mode, the Group I and Group II high voltage generators produce an output voltage (Vgen) from the power supply which equals the voltage (Vc) across the capacitive component of the load. The current through the load remains constant while the power supply tracks the voltage across the capacitive component of the load. The driving mode and the tracking mode are repeatedly performed, as the high voltage generators are driven by a square wave voltage (Vsw) produced by a timing generator (66). A control circuit (56) is also provided in the power supply to enable or disable additional Group II high voltage generators in response to fluctuations in an input voltage and the voltage across the load.

Abstract: A method and an apparatus for generating a sensor signal related a track-banking angle of a banked section of track traversed by a train car wherein a track-banking angle value basically is determined from measured values of the rolling angular speed and yaw speed of the car chassis. A track-banking angle (.phi.g) is determined in an observer unit (2), preferably estimated by use of an inverse gyro system simulation (10) of a measured-value generator (6), and compared, as an estimated track-banking angle (.phi.gb), to a track-banking angle (.phi.gs) determined from the transverse acceleration (aq), the yaw speed (.omega.G) and the train speed (v), as information about the track-banking angle (.phi.g). A resulting difference (.DELTA..phi.g) is filtered via a regulating circuit formed by a feedback from a comparator (11) to the inverse gyro system simulator (10). This signal, in the form of a track-banking angle (.phi.b), as the signal representing the real track-banking angle (.phi.g), can be fed subsequently to an angle-of-inclination generator unit (4) for generating an actuation and switching signal (.phi.N) for controlling the car chassis inclination. A further observer unit (3) can be integrated into the system for increasing the dynamics. Track path data and track geometries are stored. in this further observer unit (3), so that when a track path. is recognized, it is possible to preset a control system (5) or the actual car-body inclination system (1).

Abstract: An overhead camshaft internal combustion engine having a plastic camshaft which extends through an opening on the cylinder head, the plastic camshaft having a seal ring disposed around the outer surface of the molded plastic camshaft to provide an interface surface for contacting a seal assembly disposed between theengine casing and the molded plastic camshaft. The seal assembly and the seal ring provide a fluid tight seal to prevent leakage of fluid through the cylinder headopening. The seal ring provides a smooth contact surface for the molded plastic camshaft to prevent wear and damage to the seal assembly from the abrasive surface of the molded plastic camshaft. The seal ring also provides a heat sink for dissipating the frictional heat generated by the rotation of the camshaft.  In another form, the plastic camshaft includes a powdered metal surface formed thereon. Thepowdered metal surface provides the same benefits as the seal ring, namely protection from wear and dissipation of heat. The seal ring or the powdered metal surface may advantageously be extended to include the portion of the molded plastic camshaft in contact with a journal bearing.
