Abstract: A device may include an interface configured to receive a battery pack, a sensor configured to detect a voltage of the battery pack, an electric motor, and an electronic controller configured to: receive a sensor signal from the sensor indicative of an operating voltage of the battery pack, determine whether the operating voltage of the battery pack is greater than a threshold, in response to determining that the operating voltage of the battery pack is greater than the threshold, generate a first control signal for driving the electric motor according to a first operating parameter, and, in response to determining that the operating voltage of the battery pack is not greater than the threshold, generate a second control signal for driving the electric motor according to a second operating parameter, the second operating parameter being less than the first operating parameter.

Abstract: Extended chalcone compounds with anti-amylogenic activity were prepared and found to lack cytotoxicity and to promote neuroprotection. Testing on an animal model for Alzheimer's Disease revealed improvements in brain function using the high affinity compounds. The compounds inhibited the aggregation of A?42 but not its synthesis. The compounds can be used in new therapies for the prevention and treatment of Alzheimer's disease, including in conjunction with antibodies directed at removing amyloid plaques.

Abstract: A battery-pack-powered device includes an interface configured to receive a battery pack, a sensing circuit configured to detect a voltage of the battery pack, and an electronic controller. The electronic controller is configured to receive a first signal from the sensing circuit indicative of a no-load voltage of the battery pack, determine a threshold voltage based on the no-load voltage, generate a control signal to drive an electric motor at a first operating parameter in response to an activation of a trigger switch, receive a second signal from the sensing circuit, and update the control signal to drive the electric motor at a second operating parameter less than the first operating parameter in response to the second signal indicating that the output voltage is below the threshold voltage. The second signal is indicative of an output voltage of the battery pack during operation of the electric motor.

Abstract: A support panel including a panel body and a rail integrally formed with the panel body. The rail protrudes away from the panel body. The rail includes a surface configured to engage a mounting feature of an assembly to be mounted upon the panel body by the rail.

Abstract: A polymer composition comprising an organic polymer and a mica containing effect pigment, e.g., a pearlescent pigment comprising mica, well suited for producing molded articles, in particular, for molding articles comprising thin sections and or delicate features, such as a hollow interior defined by a thin wall or structural features susceptible to tear or other damage and the like, is provided as are a method for preparing molded articles comprising the polymer composition and articles comprising the polymer composition, including, for example, an article used to deliver a medical or personal care component such as a tampon applicator, and a method for preparing molded articles comprising the polymer composition. Optionally, articles of the present disclosure have a varying translucency or opacity about a dimension of the article.
