Abstract: An Ethernet or other communications module can amplify and reinforce a signal received from a non-local source without requiring a transformer or other magnetic component. A semiconductor integrated difference amplifier circuit can be used to amplify and reinforce a differential mode component of the received signal, while also attenuating a common mode component of the received signal. A transmission compensation network can generate a phase-shifted version of a locally transmitted signal being placed on the same communication terminals as the received signal during full duplex communications, for cancellation of such locally transmitted signal at inputs of a local receiver circuit. This can enhance detection of the received signal generated by the non-local source.

Abstract: A fuel actuation system may comprise a servo valve (SV) including a torque motor and at least one screen, a metering valve (MV) fluidly connected to the SV, and an electronic engine control (EEC) operatively connected to the SV. The EEC may be configured and disposed to determine a travel time of the MV, a travel distance of the MV, a pressure of a fuel, and/or a temperature of the fuel, generate at least one of a travel time history, a travel distance history, a fuel temperature history, and a fuel pressure history, and determine a level of degradation of the fuel actuation system based on the at least one of the travel time history, the travel distance history, the fuel temperature history, or the fuel pressure history.

Abstract: A stator comprises multiple, stacked laminations, which collectively define a core having a number of posts arranged circumferentially about the core. Each post extends into two prongs defining a first slot between the prongs. The spacing between each posts and its two prongs defines a second slot having a radially inner and outer slot. The outer slot geometry has an increasing width extending radially outward from the radially inner end, and transitioning to a decreasing width extending to the radially outer end.

Abstract: A patient transfer device is configured for use with at least one host device which is capable of providing respiratory support to a patient. The patient transfer device includes an inspiratory port and an expiratory port which are configured to pneumatically connect to the host. An inspiratory connection is pneumatically connected to the inspiratory port and an expiratory connection is pneumatically connected to the expiratory port. An inspiratory valve is coupled between the inspiratory port and the inspiratory connection and expiratory valve is coupled between the expiratory port and the expiratory connection. The inspiratory valve and the expiratory valve are operable between first configurations that permit flow there though and second configurations that occlude flow through the valves. The inspiratory valve and the expiratory valve are configured to operate in the second configuration when the patient transfer device is disconnected from the at least one host device.

Abstract: A zero-footprint remotely hosted phone application development environment is described. The environment allows a developer to use a standard computer without any specialized software (in some embodiments all that is necessary is a web browser and network access) together with a telephone to develop sophisticated phone applications that use speech recognition and/or touch tone inputs to perform tasks, access web-based information, and/or perform commercial transactions. For example, in preparation for a sales pitch for selling hosting services, a non-programmer can develop a short application appropriate to the target customer. After the pitch, access to the demonstration could be given to the target customer to allow them to more fully develop the application. When the target customer is satisfied with the application, they can have their application live for their actual (as opposed to test users) at a suitable phone number simply by having the hosting provider configure the appropriate access.

Abstract: An expiratory flow sensor system is disclosed herein. The expiratory flow sensor includes an expiratory channel adapted to transfer an expiratory gas, a fresh gas channel adapted to transfer a fresh gas, and a sensing element disposed within the fresh gas channel so that the sensing element is never directly exposed to the expiratory gas. The sensing element is configured to measure a fresh gas flow rate. The fresh gas flow rate may be implemented to estimate an expiratory flow rate in a manner that minimizes imprecision attributable to sensing element contamination.
