Abstract: A mobile device camera stand includes a flat, planar base comprising a platform for receiving a document, an adjustable shaft projecting from the base at a first end of the shaft, and a flat, planar cradle having a top surface and a bottom surface, the bottom surface connected to a second end of the shaft. The top surface of the cradle receives a mobile device having a camera, and the cradle includes a cutout such that the camera is placed on the cutout such that the cutout does not obstruct the camera, thereby enabling the camera to image the document.

Abstract: A switching power converter is configured to control switching noise by implementing a plurality of pulse width modulation modes of operation. The peak current in each pulse width modulation mode of operation is controlled so that an output power for the switching power converter is continuous with regard to transitions between the pulse width modulation modes.

Abstract: A two-terminal device that is configured to respond to a voltage modulation of an input signal received through the two terminals by triggering an action. The two-terminal device is further configured to verify a result of the triggered action by modulating a current driven through the two termi+6nals.

Abstract: An appliance support assembly including a wall bracket is provided. The wall bracket has a channel-shaped body including first and second sides which are substantially perpendicular to each other, and a third side which connects the first and second sides. The first side includes a first mounting aperture, the second side includes a second mounting aperture, and the third side includes a third mounting aperture. Guide portions operatively associated with each of the first and second mounting apertures for guiding screws through the mounting apertures are provided. An arm is pivotably connected to the bracket about a first axis at a first end of the arm.

Abstract: A method for the separation of carotenoids, especially lycopene, from fruits and vegetables, especially tomatoes. A mixture of powdered fruit and/or vegetable and an edible oil is subjected to supercritical —CO2 fluid extraction. A mixture of the oil and lycopene is separated. Lycopene of food grade quality is obtained.
