Abstract: The interproximal toothbrush includes an appliance body and neck with a nozzle member having a nozzle tip shaped to fit into interproximal teeth spaces. Bursts of air or air/liquid mixture are generated, exiting through the nozzle tip. A helix member or, alternatively, a spring, is supported within a channel in the nozzle member. The helix member is free to rotate as air or the air/liquid mixture is moved through the channel. A set of bristles is attached to a forward end of the helix member, so that it rotates with the helix member. Alternatively, a set of bristles is attached to the distal end of the spring so that successive bursts of air or the air/liquid mixture produce an in-and-out movement of the set of bristles toward and away from the teeth.

Abstract: A PET detector array (8) comprising detector pixels acquires PET detection counts along lines of response (LORs). The counts are reconstructed to generate a reconstructed PET image (36, 46). The reconstructing is corrected for missing LORs which are missing due to dead detector pixels of the PET detector array. The correction may be by estimating counts along the missing LORs (60) by interpolating counts along LORs (66) neighboring the missing LORs. The interpolation may be iterative to handle contiguous groups of missing detector pixels. The correction may be by computing a sensitivity matrix having matrix elements corresponding to image elements (80, 82) of the reconstructed PET image. In this case, each matrix element is computed as a summation over all LORs intersecting the corresponding image element excepting the missing LORs. The computed sensitivity matrix is used in the reconstructing.

Abstract: A method, enterprise information handling system (IHS), and a computer-readable storage medium provide for mitigating a noncompliant configuration of an IHS. A determination is made whether a triggering event has occurred that has a potential for degrading compliance of the enterprise IHS. In response to determining that the triggering event has occurred, a controller performs a configuration scan of the hardware and software of the enterprise IHS to obtain current configuration information. The controller determines changes in the current configuration information based on a comparison of the current configuration information with baseline configuration information that was obtained in response to a previous triggering event. A determination is made whether any changes determined in the current configuration information are non-compliant based on a comparison to compliance status information.
