Title: Method and apparatus for treating hyperarousal disorders
Inventor: MARTIN DION CHARLES CHEWE
IPC: A61M16/00
Filed: 2015-10-26
Abstract: Methods and apparatus provide automated controls for a respiratory pressure therapy device, such as a servo-ventilator. For example, a controller of a respiratory pressure therapy device may control application of pressure support ventilation therapy to an airway of a patient. The controller may control the respiratory pressure therapy device to auto-titrate an expiratory positive airway pressure (EPAP) of a pressure support ventilation therapy so as to maintain airway patency of the patient. The EPAP may be bounded below by a floor pressure limit. The controller may control the respiratory pressure therapy device to repeatedly adjust the floor pressure limit depending on events of interest during the auto-titration of the EPAP. Such methodologies may improve treatment for patients such as those suffering from sleep disordered breathing-comorbid hyperarousal disorders.

Inventor: GONCHAROV V S
IPC: C23C12/00

Abstract: FIELD: Chemical and thermal processing steel parts operated under hard conditions. SUBSTANCE: invention is aimed at increasing operational resistance of steel parts subjected to high cyclically varying temperatures and stresses, high wear, and chemical action of aggressive media by way of creating more fine-grain structure of coating. Another aim is to improve hygiene and sanitary work condition and quality of coating through using saturating components in the form of preliminarily pressed mixture of finely dispersed powders. Method consists in combining process of vacuum- diffusion saturation of surface with various components and constant temperature-cycling process which favors activation of saturation process, possibility of lowering processing temperature, reducing process duration, and producing more fine grain in the coating structure. The latter in turn promotes this coating's acquiring, along with hardness and strength, higher plasticity and thereby higher wear resistance, thermal resistance, and impact strength. To further improve quality of coating, between pressed saturating powder mixture having the shape of surface being processed and the surface itself, a clearance to avoid contact vapor-phase deposition of saturating components is available. To reduce power consumption of process and increase its output, vacuum-diffusion process is combined with subsequent heat treatment. EFFECT: improved quality of coating in many respects. 4 cl

Title: Allocation of real time files
Inventor: GESTEL WILHELMUS JACOBUS VAN
IPC: G11B20/10
Filed: 2002-12-24
Abstract: When recording data on a medium where a certain data rate is required, an allocation manager in the player must allocate sections of the logical space in such a way that the recording medium is efficiently filled and that an adequate data rate can be guaranteed even in the presence of defective ECC blocks. The allocation rules for the allocation manager are complex. The rules can be simplified by placing a lower limit on the size of an extent and by increasing the size of the extent depending on the number of defect ECC blocks in the extent.
