Abstract: An ambulatory respiratory assist device utilizes a cuirass worn on the chest and/or abdomen and supported by a hip belt so that it does not place a load on the patient's shoulders. The belt also supports a ventilator that includes a pump and its power supply, valving, controls and auxiliary equipment. The device is optionally integrated with auxiliary features such as chest wall vibration, which can be achieved by utilizing cuirass pressure modulation, with shoulder or upper arm supports for simulating the “tripod position”, with positive pressure ventilation apparatus, or with patient monitoring. Shoulder or upper arm supports can extend directly from the belt to the shoulders or upper arms, utilized independently of the cuirass, and optionally integrated with one or more of the above-mentioned auxiliary features.

Abstract: A method and an X-ray detector are for correcting a spatially resolved photon scan of the X-ray detector. In an embodiment, the X-ray detector includes processing circuitry configured to: generate, from an incident X-ray photon, a signal contribution in a first electrical signal in a spatially resolved manner, a reference value being defined by an absence of X-ray photons; resolve, in relation to the reference value, positive signal contributions of the first electrical signal and negative signal contributions of the first electrical signal; and provide the positive signal contributions resolved and the negative signal contributions resolved for further processing.

Abstract: A filter is disclosed for the spectral filtration of X-rays emanating from an X-ray source which cross an object under examination and are detected by an X-ray detector in at least two different spectral regions. After crossing the object under examination, the X-rays have an energy spectrum which displays a characteristic distribution for the anode material of the X-ray source. In an embodiment, the filter is configured to suppress part of the energy spectrum comprising the focal point of the energy spectrum. A corresponding X-ray system and method are also disclosed.

Abstract: In accordance with the aspects of the present invention, an improved book holder for reading in bed is disclosed. The present invention includes a base panel, back panel, central slotted unit and moveable plexiglass plate rectangular in shape. The plexiglass includes a windowed region such that when using the invention with an e-book reader, the controls of the e-book reader can be accessed through the windowed region.

Abstract: In accordance with the aspects of the present invention, an improved book holder for reading in bed is disclosed. The present invention includes a base panel, back panel, central slotted unit and moveable plexiglass plate rectangular in shape. Movement of the plexiglass plate to the different slotted positions allow the invention to accommodate books of any size. The user of the invention reads through the plexiglass, including the top edge thereof, to see the printed material on the open page of the book. The plate is not so large as to cover the entire printed page(s), reducing the size and weight to the invention and making it highly portable and storable.
