Abstract: The present technology includes a digital content authoring tool for authoring digital content without the need to understand or access computer code. The present technology further includes creating digital content that is compatible with a diverse population of end user devices without the need for separate versions of the completed content. Instead, the digital authoring tool can manage versions of assets, which individually, can be compatible with different device criteria. Additionally, the present technology contemplates methods of delivering packages of the digital content that are configured to be compatible with the hardware configuration of each requesting device, despite the diverse capabilities of end user devices. Accordingly, the technology described herein provides a simple method for creating and delivering digital content that is configured for presentation on a user's specific device.

Abstract: A docking station for use in combined imaging of a tissue wound and a test substrate comprising a sample from a tissue wound, the docking station comprises means for connecting the station to a processor which processes and stores the images. The docking station also incorporates means for receiving a test substrate comprising a sample from a tissue wound. The docking station also includes means for docking a sensor in the station, which sensor detects the light reflected from an illuminated tissue wound, such that an image of the tissue wound can be communicated from the station to the processor. The means for docking is arranged such that when the sensor is docked in the station and the test substrate is received by the docking station, the sensor is positioned to detect the intensity of reflected light from the test substrate and communicates the detected intensity of reflected light to the processor to thus permit combined imaging of the tissue wound and test substrate.

Abstract: In accordance with the preferred embodiment and alternative embodiments of the invention, RFID network control devices (RNCDs) are provided wherein RFID traffic signals from any one of multiple RFID readers may be routed to any of the RFID antennas coupled to the RNCD. Each reader coupled directly or indirectly to the RNCD, either through its own action or the action of the external host controller managing the reader, may issue commands to the RNCD, over the same cable used to carry RFID traffic signals, and cause the RNCD to set its internal switch configuration such that a channel is established for RFID traffic signals between that reader and a particular RFID antenna coupled to the RNCD. This may include commands from the reader or external host controller which place other intervening RNCD units in a bypass state so as to establish the required communications channel with a minimum of signal strength loss.

Abstract: Disclosed is an integrated process for producing 2,6-naphthalene dicarboxylicacid comprising oxidizing a methylnaphthalene feedstock, hydrodebrominating the crude naphthoic acid product under conditions different from any work known in the art, forming a potassium salt of the acid; disproportionating the potassium salt to produce 2,6 potassium salts of NDA; selectively precipitating K2NDA; selectively precipitating the monopotassium salt of 2,6 NDA(KHNDA); disproportionating the KHNDA into 2,6 NDA and K2NDA; further reacting the 2,6 NDA in a pipe reactor; and drying the product 2,6 NDA by conventional means or directly slurrying directly into a PEN process. The process can tolerate impurities in the economical methylnaphthalene feed and the resulting 2,6 NDA is of high quality with <50 ppm potassium.

Abstract: A disposable light handle is designed for removable attachment to manually adjustable light fixtures employed in sterile medical settings. The light handle includes an elongated handle body, having one end closed, and an opposite end provided with a threaded portion. At the junction of handle body and threaded portion is an integrally formed circular shield that projects therefrom to provide a guard against contact between the hand of a user and the light fixture. The shield is sufficiently resilient and flexible to permit opposite sides of an outer periphery to bend into an overlying relationship to the handle body for minimizing width in storage. The shield is provided with loops located diametrically opposed to one another on the periphery of the shield. Connector projections are diametrically opposed to one another along the length of the handle body, and positioned to releasably receive thereon the loops when the shield is bent into an overlying relationship.

Abstract: A video/graphics overlay integrated circuit receives an analog composite video signal and a digital composite video signal and combines them in a predetermined format into an output composite video signal which is transmitted to a display device such as a television set. The digital video signal may be comprised of digital video, graphics data or a combination of digital video and graphics data. The digital video and graphics data are encoded by a digital encoder integrated circuit into a digital composite video signal. The digital composite video signal is coupled to the video/graphics overlay integrated circuit. An automatic phase correction circuit detects any phase difference between the burst signals of the analog composite video signal and the digital composite video signal.

Abstract: A video/graphics overlay circuit receives an analog input composite video signal and a digital input composite video signal and combines them into a linear combination output composite video signal depending on the state of one or more mixer control signals. The two composite video input signals are each capacitively coupled to buffer and clamp circuits through which the blank or DC level of each signal is clamped to two volts. The outputs of the buffer and clamp circuits are then fed to a mixer circuit and burst separator circuits. The mixer circuit generates the output composite video signal which is a linear combination of the input composite video signals as controlled by the one or more mixer control signals. The burst separator circuits separate the burst signal from the input composite video signals. The extracted burst signals are then provided to a burst signal phase-locked loop for locking the burst signals of the input composite video signals in phase.

Within this main compartment a mirror, two contact lens storage compartments and two bottles with lens care fluids may be stored. The bottles' tops may be color coded to indicate the particular fluids therein. Exterior of the main compartment are additional two screw-on lens compartments. A clip on the container allows attachment to a user's clothing much like a phone pager.

Abstract: A mixer control circuit generates content control signals which are used by a mixer circuit to control the content of an output signal. The output signal will include either an analog signal, a digital signal or a mixture of the analog and digital signals. The level of a digital content control signal corresponds to the percentage of the output signal which includes the digital signal. The level of an analog content control signal corresponds to the percentage of the output signal which includes the analog signal. When the output signal includes a mixture of the analog and digital signals, a differential pair and an external control voltage are used to specify the percentage of each signal to be included within the output signal. During a horizontal blanking period, when the signals are being mixed, the differential pair and the external control voltage are bypassed and only the analog signal is included within the output signal.
