Abstract: Presented herein are techniques to process an image for a video conference. A method includes obtaining an image from a camera, identifying a first person and a second person in the image, labeling pixels in the image belonging to the first person and to the second person, determining a first distance between the first person and the camera and a second distance between the second person and the camera, and based on the first distance and the second distance, selectively removing or blurring at least one of the first person and the second person from the image, before transmitting the image to an endpoint of a video conference, by manipulating the pixels in the image belonging to the at least one of the first person and the second person.

Abstract: A power supply for a smooth power output level transitioning includes an energy storage circuit for temporarily storing electric energy for driving a load, a semiconductor switch for pulse-width modulation (PWM) switching, and a digital PWM controller. The digital PWM controller generates a driving waveform to regulate on and off status of the semiconductor switch. The driving waveform toggles between PWM periods of a first type and PWM periods of a second type, and gradually adjusts a ratio of numbers of the PWM periods of the two types over time. The toggling driving waveform achieves one or more intermediate finer power output level that cannot be realized by a single type of PWM period with an intermediate duty cycle, due to the minimum item unit of the driving waveform limited by a clock rate of the digital PWM controller.

Abstract: The present invention provides an adjustable, universal screed guide/control joint clip for positioning screed guide/control joints utilized in the placement of concrete in concrete slabs. The adjustable universal screed guide clip allows for the exact adjustment of the height of the screed guide attached thereto for the placement of the concrete slabs, and the adjustable universal screed guide clip also allows for the installation of the screed guide in applications which heretofore were not possible. The adjustable, universal screed guide/control joint clip of the present invention is capable of accommodating both large and small profile screed guides.

Abstract: What is disclosed is an apparatus and method for assembling a reconstitution assembly (1) having a reconstitution device (10) having a first end connected to a flexible diluent container (12), the reconstitution device (10) having a second end connected to a drug vial (14). The reconstitution device (10) and containers, such as drug vials (14) or diluent bags (12), are loaded onto positioning assemblies (27) on a conveyor (90). The positioning assemblies (27) are conveyed to sterilization booths (270). Sterilization fields are generated within the sterilization booths (270), and the containers are sterilely connected to the reconstitution device (10) within the sterile fields.

Abstract: A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration.

Abstract: Methods and apparatus include a handheld printer manipulated back and forth by an operator during use to print an image. An inkjet printhead of the printer has a plurality of fluid firing actuators arranged in a substantial column. A controller communicates with the printhead to identify active actuators given to fire at a particular time during use to print the image. However, to prevent unsightly print quality from occurring during overlapping adjacent print swaths, for example, certain of the identified actuators are prevented from firing. Especially, actuators in the column further from a center of the column fire less frequently than those closer to the center. A position sensor is also used to locate the printhead relative to the image. The controller correlates the position to the printhead and actuators and fires the active actuators or not.

Hand-held printing device having at least one antenna and a controller adapted to calculate the relative position of the hand-held printing device by comparing received radio signals on the antennae. Methods for using the same.

Abstract: Methods and apparatus include a handheld printer manipulated back and forth by an operator during use to print an image on a media. The media includes reference indicia upon which users maneuver the printer whenever a location of the printer is unknown or needs updating or validating. A controller of the printer correlates the location of a printhead to the image and when lost communicates to a direction indicator to provide user notification of where to move the housing to reacquire the location. Embodiments of the reference indicia include guide and location patterns, with the guide pattern pointing to the location pattern. Other indicia include related tick marks of substantially equal size and shape with substantially equal spacing there between. Supply items for applying on the media include a substrate with reference indicia thereon that matches stores reference indicia in the printer.

Abstract: Methodology for preparing print jobs for hand printer. Pages are parsed into objects that are printed separately and thus reduce the requirement for navagational accuracy that is required for printing complete pages. When each object is printed, a target mark applied to the page allows the user to position the hand printer for the next object to be printed. This enables design of hand printers with lower cost position sensors.

Abstract: Stand-alone hand-held printers comprising a housing, a printhead, one or more sensors, and a display. The one or more sensors are adapted to detect relative position of the print head during an ongoing print job. The hand-held printer is configured to show one or more print quality features of the ongoing print job on the display. Systems including the hand-held printer.

Abstract: The present invention provides a learning environment that presents information in an organized fashion with defined objectives using an extension of current 3D online technology. By combining 3D virtual space technology with additional asynchronous and synchronous communications features, a content rich learning environment can be created that allows students more realistic interactions than those provided by currently deployed systems. In addition, the system allows for the overlay and integration of 2D, text-based, and audio-based learning tools both within and outside the 3D environment and provides an interface with convergence technology such as cell phones, pagers, hand held computers, etc as well as collaborative tools such as presentation of overheads, computer software slide presentations such as MICROSOFT POWERPOINT, whiteboard, virtual network computing (VNC), and for class lectures, whiteboard, virtual network computing (VNC), and other collaborative tools layered into the 3D environment.
