Control of a head-mounted display includes providing a head-mounted display, the head-mounted display includes a switchable viewing area that is switched between a transparent viewing state and an information viewing state. The transparent viewing state is transparent with respect to the viewing area and enables a user of the head-mounted display to view the scene outside the head-mounted display in the user's line of sight. The information viewing state is opaque with respect to the viewing area and displays information in the switchable viewing area visible to a user of the head-mounted display. A user-state detector provides an external stimulus notification in response to a detected change in the biological state of the user and causes the viewing state to automatically switch in response to the external stimulus notification.

The invention is a device for the introduction of a fluid into a human's airway. The air so introduced has a carefully modulated envelope of pressure vs. time, this envelope generally consisting of sequences of pressurized air packets of controlled frequency and pressures. The device produces these packets by means of pressurized air occluded by a shutter action which “chops” and interrupts the fluid stream. The vibrations induced by the device within human organs have been shown to have beneficial effects on various bodily systems, such as increase in heart rate variability, increase in absorbed oxygen, decrease in absorbed CO2, and the like.

Process for the automatic control of a respirator

Номер: US20120152249A1
Автор: Frank Sattler, Hans-Ullrich Hansmann, Marcus Eger, Tobias GLAW
Принадлежит: Draëger Medical GmbH

A process for the automatic control of a respirator with a changeover between phases of respiration (inspiration and expiration), by a control unit checking a breathing activity signal for a threshold criterion. If the threshold criterion is met, a changeover is made and the control unit controls the fan of the respirator such that a pneumatic respiration variable (airway pressure, flow) is brought from an actual value to a preset target value for the new phase of respiration. The control unit further divides the change in the respiration variable, from the actual value to the target value, into a plurality of partial steps and checks the current breathing activity signal for the threshold criterion after each partial step. If this threshold criterion is no longer met, the state of operation of the respirator returns to the state before the last changeover, and otherwise, continues with the next partial step.

Method and apparatus for machine error detection by combining multiple sensor inputs

Номер: US20120194335A1
Автор: James M. Brugger, Jeffrey H. Burbank
Принадлежит: Nxstage Medical Inc

One of the most significant safety concerns in the automation of extracorporeal blood treatments such as dialysis is the risk of blood leakage. Extracorporeal blood treatment systems draw blood at such a high rate that a loss of integrity in the blood circuit can be serious. There are a number of mechanisms for detecting and preventing leaks, but none is perfect. This tends to limit the use of such equipment in unsupervised settings, such as the home will be limited. Some leak detection schemes can be made sensitive enough to detect the barest of leaks, but when this is done, they result in too many false positives. The invention combines information from multiple inputs to enhance sensitivity in leak detection and reduce the problem of false positives.
