Abstract: A tethered imaging camera encapsulated in a shell lens element of such camera enables viewing from inside and imaging of a biological organ in/from a variety of directions. A portion of camera's optical system together with light source(s) and optical detector mutually cooperated by housing structure inside the shell are moveable/re-orientable within the shell to vary a desired view of the object space without interruption of imaging process. A tether carries electrical but not optical signals to and from the camera and controllable traction cords to move the camera, and a hand-control unit and/or electronic circuitry configured to operate the camera and power its movements. Method(s) of using optical, optoelectronic, and optoelectromechanical sub-systems of the camera.

Abstract: In one embodiment of the present invention, a filtration device can include a chamber; magnetic objects configured to bind or adhere to one or more components of a fluid; and, at least one magnet disposed on an outer surface of the chamber, wherein the chamber comprises an inlet through which the fluid may be introduced and an exit through which the fluid may be removed, at least one magnet is configured to produce magnetic fields within the fluid, and the magnetic objects are configured to move within the fluid in response to magnetic fields produced by at least one magnet. Related methods and systems are also disclosed.

Abstract: A method of controlling a resistive switching memory cell can include: receiving a first command to be executed on the resistive switching memory cell; performing, in response to the first command, an erase operation to erase the resistive switching memory cell to an erased state; verifying the erased state of the resistive switching memory cell; performing a weak program operation to program the resistive switching memory cell to a first programmed state; and verifying the first programmed state of the resistive switching memory cell.

Abstract: In a refrigerated fruit store 1, the atmosphere is controlled to low levels of oxygen and carbon dioxide using an activated carbon bed 2, by continuously repeating the following cycle of operations:(1) expose the carbon in the bed 2 to the atmosphere in the fruit store 1, until saturated with CO.sub.2 (12 minutes);(2) evacuate the bed 2, down to 7 kPa, to the gas reservoir 5, whereby the O.sub.2 and N.sub.2 (but not CO.sub.2) are released in "fruit store" proportions into the reservoir (2 minutes);(3) expose the bed 2 to air to purge it of the CO.sub.2 (18 minutes);(4) evacuate the bed 2 to waste (7 kPa is adequate) to remove O.sub.2 and N.sub.2, which would otherwise remain in the bed in substantially "air" proportions (i.e. excessive oxygen) (2 minutes);(5) expose the bed 2 to the gas put in the reservoir 5 at operation (2) above, so that the bed 2 now contains O.sub.2 and N.sub.2 in "fruit store" proportions (2 minutes);(1) expose the adsorptive medium to chamber atmosphere; and so forth indefinitely.
