Abstract:
A linear motion sensing system for sensing at least shaft position of a linear moving shaft of a linear motion device includes a sensed structure associated with and moving linearly in unison with the linear moving shaft; a light sensor assembly including a light emitter emitting light directed at the sensed structure and a light detector receiving light from the light emitter, the light sensor assembly emitting signals indicative of at least position of the sensed structure; and a sensor module receiving the signals indicative of at least position of the sensed structure from the light sensor assembly and determining at least shaft position of the linear moving shaft of the linear motion device.
Medical Ventilator System And Method Using Oxygen Concentrators
A medical ventilator system that allows the use of pulse flow of oxygen to gain higher FIOvalues and/or conserve oxygen is described. In one embodiment, the ventilator system includes an oxygen concentrator, a medical ventilator and a breathing circuit between the ventilator and a patient. In one embodiment, the oxygen concentrator includes a controller module that is configured to generate a trigger signal to initiate the distribution of one or more pulses of oxygen from the oxygen concentrator to the patient circuit at the onset of a ventilator supplied breath. A small flow of oxygen can be added in between pulses to aid in gaining higher FIO.

Abstract:
Disclosed are methods, systems, apparatus, and products, including a method for operating a respiratory care device that includes collecting at a respiratory care device data representative of operation of the respiratory care device, and communicating to a computing-based device external to the respiratory care device at least some of the collected data to control the operability of the respiratory care device. In some embodiments, the method may further include communicating to the respiratory care device data to controllably change one or more operation parameters of the respiratory care device to cause a change in the operation of the respiratory care device, changing the operation parameters of the respiratory care device according to the communicated data, and communicating to the external computing-based device resultant data representative of operation of the respiratory care device resulting from the controllable change to the one or more operation parameters.

Abstract:
Disclosed are devices, systems, and methods, including an oxygen delivery device that includes an oxygen delivery module, at least one sensor to detect patient breathing, and a controller configured to control the oxygen delivery module to cause the oxygen delivery module to deliver oxygen to the patient based on data from the at least one sensor such that in response to a determination, based on data from the at least one sensor, that no breathing is detected for a first pre-determined period of time, the controller causes the oxygen delivery module to deliver oxygen to the patient in continuous flow mode, and in response to a determination, based on additional data from the at least one sensor, that breathing is detected for a second period of time, the controller causes the oxygen delivery module to deliver oxygen to the patient in a pulse flow mode.

Abstract:
Disclosed are devices, systems, and methods, including an oxygen delivery device that includes an oxygen delivery module to produce at least concentrated oxygen, a gas moving device to deliver air to the oxygen delivery module, at least one motor to controllably drive the gas moving device, an energy source to power at least the at least one motor, a pressure sensor to determine a pressure level, and a purity sensor to determine oxygen purity value. The device also includes a controller to control, based on the oxygen purity value and the pressure level, at least the gas moving device's operations and the oxygen delivery module's operations to cause the pressure resulting from gas moving device to be substantially at a pre-determined pressure value and to cause the purity level of the oxygen produced by the oxygen delivery module to be substantially at a pre-determined purity value.
