Abstract: A system for evaluating a cell sample may comprise a specimen slide scanner, a computer-based image analyzer, and an evaluation subsystem. The specimen slide scanner may be configured to acquire images of an entire surface of a microscope slide upon which the cell sample is mounted. The computer-based image analyzer may be configured to identify one or more follicular clusters within each of the images acquired by the specimen slide scanner. The evaluation subsystem may be configured to (i) compare a number of follicular clusters identified by the computer-based image analyzer to an adequacy threshold, and (ii) present an adequacy notification to a user when the number of the follicular clusters identified by the computer-based image analyzer exceeds the adequacy threshold.

Abstract: An atomizing spray dryer employs one or more stages defined by ultrasonic transducers in close proximity to a liquid feed opening forming a path of an atomization flow for producing uniform droplets from a close tolerance with the transducer. The atomization flow exits a gap between the transducer and an outer edge of the opening, such that the passed liquid is responsive to an oscillation of the transducer for forming the droplets. A conical or other suitably shaped transducer engages a substantially round liquid feed opening. Subsequent stages may include a circular, ring, or other suitable shape aligned to receive the atomization flow from a circumference of the conical base, or may also take any suitable shape, preferably to receive droplets directed by the first stage.

Abstract: Devices and methods for generating electricity in a direct carbon fuel cell are provided herein. The method includes heating and melting an alloy to obtain a liquid alloy anode; circulating the liquid alloy anode through a porous ceramic cathode, the cathode being a tubular structure and in communication with oxygen; reducing the oxygen at the porous cathode to obtain oxygen ions for diffusing through an electrolyte to the liquid alloy anode; and oxidizing the oxygen ions at the liquid alloy anode thereby generating electricity. The direct carbon fuel cells have high electronic conductivity, high carbon solubility with fast carbon diffusion, lower viscosity and eutectic temperatures, and rapid fuel dissolution kinetics.

Abstract: A motorized introducer apparatus for translating an elongate shaft of an endoscope relative to a patient may include a body, a motor fixedly attached to the body, a drive gear coupled to the motor, a drive wheel coupled to the drive gear, and a support wheel positioned adjacent the drive wheel. The elongate shaft of the endoscope is disposable between the drive wheel and the support wheel at an engagement location such that the elongate shaft is configured to selectively move longitudinally along an axis of movement. A surgical system may include the motorized introducer apparatus and a support frame attachable to a surgical bed. The motorized introducer apparatus may be secured to the support frame.

Abstract: A colonoscopy screening device includes an elongated flexible probe having a proximal end and a distal end, the distal end adapted for rectal insertion, and an electrode at the distal end and adapted for contact with a suspect tissue growth. A measurement circuit connected to the electrode for measuring an electrical characteristic of the suspect tissue growth based on delivery of an electrical signal from the electrode. A pair of electrodes in an opposed orientation allows an actuator to drawing at least one of the electrodes towards the other electrode for engaging the suspect tissue growth for passing the electrical signal through the suspect tissue growth. Measurement of the resulting signal determines bioelectrical properties of the growth for determination of possible malignancy.

Abstract: A method of optimizing vehicle mobility performance includes receiving technical parameters for each wheel associated with wheel power of the particular wheel on a particular terrain. The method includes determining an optimal vehicle mobility performance by determining an optimal tire slippage for one wheel based on the set of technical parameters for the wheel and individually determining an optimal tire slippage for another wheel based on the set of technical parameters for the other wheel. A system may utilize such a method to control mobility performance in a vehicle such as, but not limited to, an autonomous ground vehicle.

Abstract: A passive vortex formed or induced from a temperature difference across a cavity or void aggregates and supports a horizontal flow over the top of the cavity. A cavity of a suitable depth and width exhibits a small difference in temperature, or heat source, along the sides or bottom of cavity. A resulting convective flow tends to form a rising current along a warmer side, and a complementary downward current on an opposed side of the cavity. The formed vortex tends to draw the cooler downward flow across the warmer, heated surface, enhancing the vortex flow. The vortex aligns with a horizontal flow across the top of the cavity as the upward current complements the downward current on an opposed side of the cavity. A plurality of adjacent cavities tend to align with an aggregate horizontal flow contributed from each cavity.

Abstract: A fiber optic sensing device includes an optical fiber having a polished end defining a flat sensory portion coated with a lossy-mode-resonance (LMR) coating. A reflective coating on an end face of the optical fiber facilitates propagation of a return signal. An optic circuit for identifies a wavelength attenuated by the LMR coating from the return signal reflected by the reflective coating based on a moisture presence at the sensory portion. Various gaseous parameters may be detected based on the coating on the sensory portion. An LMR coating of tin oxide (SnO2) is employed for moisture sensing.

Abstract: An ultrasonic imaging configuration rendering an image based on a reflected beam aligned with a needle insertion axis provides enhanced images and guidance. A percutaneous insertion guidance device for ultrasonic (US) imaging includes an US transducer and a reflector for redirecting imaging signals between the transducer and an imaged region. An enclosure or bracket is adapted to support the reflector at a predetermined angle based on a surgical target in the imaged region such that a forward beam direction from the transducer reflects in a direction of the needle insertion as the needle passes through a discontinuity or slot in the reflector. The resulting return signal is based on an axial alignment of the US signals with the needle travel towards the surgical target.
