Abstract: A dental mouthpiece is provided that may be attached to a high-suction dental adapter for the purpose of assisting the dental staff during dental procedures through chair-side, hands-free suction, and isolation. Such a mouthpiece may include a main body portion, a cheek retractor portion, and a suction connector portion. In some embodiments, the main body portion, cheek retractor portion, and suction connector portion (and sub-portions thereof) may be molded in one piece, preferably by injection molding. In an exemplary embodiment, the mouthpiece may be made of a material that is flexible, translucent, conducive to injection molding, high heat-resistant, and autoclavable. Such a material may include silicone. Because the mouthpiece may be made of a high heat-resistant and autoclavable material, such a mouthpiece may be reusable.

Abstract: A distributed amplifier system comprising an impedance matching network configured to match an input impedance to an output impedance of the signal source, and a DC block configured to block DC components in the input signal. A variable gain amplifier adjusts the gain applied to the input signal based on a gain control signal to generate a gain adjusted signal. An emitter follower circuit receives and processes the gain adjusted signal to introduce gain peaking to create a modified signal. A distributed amplifier receives and amplifies the modified signal from the emitter follower circuit, to create an amplified signal. The distributed amplifier includes a termination network and one or more impedance matching elements configured for gain shaping the amplified signal. The gain peaking introduced by the emitter follower circuit is controlled by a variable current source. The distributed amplifier may be an open collector distributed amplifier.

Abstract: An enhanced electrical circuit can employ conductive fill components that can facilitate providing desirable resistive stabilization of the electrical circuit and other desirable circuit qualities without having to use a physical resistor. The electrical circuit can comprise a transmission line, which can be a microstrip line, that can have defined dimensions. The electrical circuit can comprise respective conductive fill components that can be in proximity to desired sides of the transmission line, wherein the respective conductive fill components can provide the desired resistive stabilization for the electrical circuit. The respective conductive fill components can be separated from, and not in contact with, each other based on respective gaps of a defined size(s) between respective adjacent conductive fill components. The respective conductive fill components can be across a single layer or multiple layers of conductive fill components.

Abstract: Systems and methods for generating optical character recognition (OCR) models configured to identify characters from a variety of different documents. The OCR models are based on a base model. One or more outside models can be tested to determine their effectiveness in supplementing the base model. When an outside model is effective it is incorporated into the base model. Generations of base models can be created that provide for additional functionality that is not present in the preceding model. A family of the generations of base models is maintained.

Abstract: Systems and methods related to serial communication devices are provided. An example integrated circuit (IC) device includes interface circuitry coupled to a two-wire serial communication bus having a serial clock (SCL) line and a serial data (SDA) bus line. The IC device further includes bus stuck recovery circuitry to monitor for a local SDA fault condition at the IC device based on a number of clock cycles during which an internal SDA signal (e.g., generated by the IC device) drives the SDA bus line to a first signal state, the clock cycles based on a clock signal received from the SCL line; and responsive to the local SDA fault condition, release the SDA bus line independent of the internal SDA signal, where the SDA bus line is in a second signal state different from the first signal state based on the release.
