Abstract: A system is described comprising self-propelled bodies such as bacteria or nanoparticles, which can be activated with an external field to move in a desired direction. The self-propelled bodies, or swimmers, are contained in a flexible membrane which is mechanically manipulated through the movement of the swimmers. By controlling the applied field, which can be magnetic, chemical or gravitational, the flexible membranes can be translated and/or deformed.

Abstract: Apparatus for generating accurate 3-dimensional images of objects immersed in liquids including optically opaque liquids which may also have significant sound attenuation, is described. Sound pulses are caused to impinge on the object, and the time-of-flight of the reflected sound is used to create a 3-dimensional image of the object in almost real-time. The apparatus is capable of creating images of objects immersed in fluids that are optically opaque and have high sound attenuation at resolutions less than about 1 mm. The apparatus may include a piezoelectric transducer for generating the acoustic pulses; a high-density polyethylene compound acoustic lens, a 2-dimensional segmented piezoelectric detecting array positioned behind the lens for receiving acoustic pulses reflected by the object, the electric output of which is directed to digital signal processing electronics for generating the image.

Abstract: Provisioning and management resources are drawn from an overall pool of resources. Management and managed resources are then dynamically associated on the network to securely perform requested on-demand management functions. Since the managing system controls the networking between the devices that are managed or provisioned, the linkage of resources incurs a minimal amount of network overhead. Since provisioning resources are themselves dynamically built and automatically associated with the resources being managed, a dramatically reduced management overhead is achieved.

Abstract: Resources are rapidly provisioned using a repeatable, error free deployment technique. The technique includes an automatic throttle of a build management node to conform to existing network limitations in order to maximize the number of build operations which can be performed concurrently, while queuing up remaining requests to be executed, in response to sufficient network bandwidth becoming available.

Abstract: An integrating capacitor circuit for an integrating amplifier and related methods are disclosed that allow for efficient detection of currents or charges, particularly those produced by pixel cells in a detector image array. By placing a capacitor-connected field-effect-transistor (FET) in parallel with an integration capacitor and setting its gate voltage to a selected voltage level, the current or charge from the detector depletes the charge on the gate of the FET capacitor while integrating on the capacitor. In addition, the gate voltage level can be adjusted to modify the current depleting characteristics of the capacitor-connected FET. The resulting operation of this integrating circuitry provides significant resulting advantages for the integrating amplifier.

Abstract: A method for measuring the temperature of a scene using a detector having at least one reference pixel, with an integratable sampling circuit associated with each pixel. Initially, an ambient reference temperature is observed with the reference pixel(s) to provide a parameter, generally voltage, indicative of that temperature to provide a constant voltage output indicating that temperature by varying the sampling circuit integration time. Each non-reference pixel is exposed to different scene and ambient temperatures and the integration time for each set of data for each pixel is recorded. For each pixel, an equation is provided relating integration time to pixel voltage when the ambient temperature and the scene temperature are the same to correct for offsets and an equation is provided relating integration time and offset corrected pixel value to the difference between the ambient temperature and the scene temperature when the ambient temperature and scene temperature differ for correction of responsivity.
