An electrostimulation device includes a computer generating an electrostimulation generator control signal and outputting a music signal, a transcutaneous electrostimulation generator, an electronic signal conduit, and an electrode coupler. The generator receives the generator control signal and the music signal, generates a nerve electrostimulation signal dependent upon the generator control signal, and outputs the nerve electrostimulation signal at the stimulation output and the music signal at an audio output. The coupler fits in an ear canal, has a speaker connected to the audio output to output the music signal into the ear canal when worn, and has electrostimulation electrodes conductively connected to the stimulation output through the electronic signal conduit to receive the nerve electrostimulation signal and positioned to contact tissue within the canal to transcutaneously apply the nerve electrostimulation signal thereto. The coupler supplies the nerve electrostimulation signal while music outputs from the speaker.

Systems and methods are provided for allowing an implantable medical device, such as pacemaker, to properly sense electrophysiological signals and hemodynamic signals within a patient during a magnetic resonance imaging (MRI) procedure. Systems and methods are also provided for allowing the implantable medical device to transmit the sensed data to an external monitoring system during the MRI procedure so that attending medical personnel can closely monitor the health of the patient and the operation of the implantable device during the MRI. These improvements provide the attending personnel with information needed to determine whether the MRI should be suspended in response to induced tachyarrhythmias or other adverse conditions within the patient.

A device, using which signals and energy may be transmitted without contact between an electrical device on or in the vehicle body and an electrical device on or in a vehicle seat, reliable signal and energy transmission being ensured even in the event of frequent changes of the seating configuration, without the vehicle user having to take special precautions for this purpose. The two electrical devices are each assigned a transmission module. These transmission modules form a high-frequency wireless transmission path. The transmission module on or in the vehicle body is integrated into the rail system for the vehicle seat, while the transmission module on or in the seat may be coupled into the rail system in such a way that the signal and/or energy transmission occurs via the displacement current generated in the rail system.

For detecting closing or opening of a valve activated preferably by a solenoid actuator, a switch activated by a tappet spring mounted on an armature of the actuator is provided. A stop and an associated surface limit the stroke of the tappet with reference to the switch. Preferably, a valve closing element opens the gas flow only when the armature has already executed a part of its opening stroke. The trigger point of the switch is set in this first part of the opening stroke of the armature, in which the valve closing element has not yet opened. The stroke limiting of the tappet for activating the switch is also preferably set in this region of the opening stroke of the armature. However, the stop limits the stroke of the tappet independent of the opening stroke size of the armature, so that the same switch can be used for different valves with different nominal diameters and opening strokes.

A counter increases a counted value at regular time intervals during a transmission time of a request signal Sr transmitted based on trigger signals input from a door unlocking sensor or the like. On the other hand, the counter decreases the counted value at regular time intervals during a non-transmission time of the request signal Sr. A determination unit either prohibits or permits transmission of the request signal Sr to a portable unit, based on comparison results of the counted value with a prohibition value and a lifting value.

A method and apparatus for receiving a modulated signal which consists of N subcarriers containing N-L (L<N) nullcarriers and in which an effective symbol has a length T, and a frequency interval between two adjacent subcarriers of the N subcarriers is 1/T. The method includes estimating an excess delay of a delayed wave, and deciding a part of the symbol regarded as a to-be-used symbol, based on the estimated excess delay, where a length of the decided part is TM/N (M<N) within the effective symbol length T which is decided so as not to contain a part of the symbol suffering from a waveform distortion caused by the delayed wave; and decomposing a complex digital signal which is quadrature-detected at sampling intervals T/N into L subcarriers by use of M samples of the signal within the to-be-used symbol part by means of a matched filter.

Embodiments include providing reliable Session Initiation Protocol (SIP) signaling for Web Real Time Communications (WebRTC) interactive flows, and related methods, systems, and computer-readable media. In one embodiment, a method for providing reliable SIP signaling for WebRTC interactive flows comprises establishing, via a stateless SIP user agent executing on a first web server, a WebRTC interactive flow between a WebRTC client executing on a computing device and a remote endpoint. The method further comprises receiving, by the WebRTC client, a call state from the stateless SIP user agent, the call state indicating a current state of the WebRTC interactive flow. The method also comprises storing, by the WebRTC client, the call state. In this manner, the call state of the WebRTC interactive flow may be accessible for restoring the WebRTC interactive flow in the event of an unexpected termination of the WebRTC client and/or the stateless SIP user agent.
