A method for generating a trigger signal for a magnetic resonance measurement by an R wave of an EKG signal is proposed. The EKG signal is captured by an algorithm manager. The algorithm manager includes at least a first trigger instance having a trigger algorithm. EKG signals from at least two different EKG channels are processed by the trigger algorithm. The algorithm manager includes at least a further trigger instance for capturing the EKG signal. The further trigger instance has at least one further trigger algorithm for processing EKG signals from at least two different EKG channels. The trigger signal is generated by selecting a trigger instance from the different trigger instances.

A receptacle connector is provided for mounting on a printed circuit having a contact mounting area and an incoming trace that extends into the contact mounting area. The receptacle connector includes a housing having a slot configured to receive a mating connector therein. The receptacle connector also includes an upper contact and a lower contact held by the housing. The upper and lower contacts include mating segments, mounting feet, and intermediate segments that extend between the mating segments and the mounting feet. The mounting foot of the lower contact is configured to be mounted on the incoming trace of the printed circuit such that the mounting foot creates a conductive path between the incoming trace and the intermediate segment of the lower contact. The conductive path forms part of a propagation path of electrical current through the electrical trace and the lower contact.

An aging detection circuit is disclosed. An aging detection circuit may include at least an inverter and a half-latch. During a power-up sequence, if an input voltage of the first inverter changes sufficiently to cause the output of the inverter to change states, the output of the half-latch may be set to a state indicating aging of the circuit. This indication may be used in determining whether or not a supply voltage should be changed to compensate for the aging. A first transistor of the inverter may be arranged such that it remains active subsequent to power-up of the circuit. When active, the first transistor may be subject to degradation mechanisms associated with aging and which change its threshold voltage. The threshold voltage may change such that on a successive power-ups of the circuit, the first transistor is at least momentarily deactivated, leading to the setting of the state indicating aging by the half-latch circuit.

An electric machine contains a rotor which contains a first longitudinal section at the ambient air temperature and a second longitudinal section cooled at least partially to cryogenic temperature, a coolant inlet pipe extending into the second longitudinal section, wherein the inlet pipe is set at a distance from the rotor by a radial gap, wherein the inlet pipe in the first longitudinal section is mounted by at least two bearings, wherein the bearings are distributed on axial positions in such a way that upon action of a maximum radial force on the inlet pipe the pipe has a maximum deflection which is smaller than the radial gap. In a method for determining the axial positions, various batches of potential locations are chosen for the axial positions of the bearings, according to potential locations which has a minimum gap greater than zero.

An infrared heater for heating a cooking vessel, such as a Chinese wok. The heater includes a block of refractory material, which emits infrared radiation upon heating to an elevated temperature, forming an inverted frustum-shaped cavity or opening. A gas-fired burner having a burner head which produces a laterally directed flame upon ignition of a mixture of a fuel gas and a combustion oxidant supplied to the burner is disposed in the cavity or opening. A planar structure suitable for emitting infrared radiation upon heating to an elevated temperature and forming at least one centralized opening covers the upward oriented base end of the inverted frustum-shaped opening. In accordance with one embodiment, the refractory block is disposed within a cylindrical housing which supports the cooking vessel above the centralized opening during the cooking process.

Disclosed is graphically representing each of a number of measurement data sets as a variation of at least one parameter, wherein each measurement data set results from a measurement, by: [A] selecting a plurality of the measurement data sets to be graphically represented, [B] graphically representing one of the selected measurement data sets as a primary measurement data set in a first graphical style, and [C] graphically representing each one of the at least one remaining selected measurement data sets as secondary measurement data set in a graphical style deviating in at least one feature from the first graphical style. Upon a first change request, a different one of the selected measurement data sets is graphically represented as the primary measurement data set in the first graphical style, and continuing with [C].

System and method for decompressing data. A compressed data stream including contiguous variable length data blocks is received, each variable length data block including multiple contiguous variable length data fields. A current data block of the contiguous variable length data blocks is stored in one or more registers of a processor. Decoding state information is stored in another register of the processor. A single machine instruction of the processor is loaded. The instruction includes one or more operands corresponding respectively to the one or more registers, and another operand corresponding to the other register, where the other register is further operable as a destination register to store a result of the machine instruction. The instruction is executed to decompress the current data block using the stored decoding state information, including storing the decompressed current data block in the other register. The decompression is repeated for subsequent blocks in the stream.

A method for identifying R-waves in an ECG signal for the purpose of triggering further measurements or examinations is proposed. A reference ECG signal by an ECG measuring device is measured. An R-wave in the reference ECG signal is identified. A reference quantity is determined from the reference ECG signal. The reference ECG signal assumes in a time interval that starts before the R-wave of the ECG signal and lasts at a maximum up to the occurrence of the R-wave. A comparison rule is generated based on the reference quantity. ECG signals are measured in which R-waves are to be identified. The measured ECG signals are compared with the reference quantity based on the comparison rule. A trigger signal is outputted based on a positive result of the comparison.

In a method and a device for detecting the surroundings, carrier waves in the form of transmission pulses are transmitted by at least one transducer, and reflections of the pulses are detected by the pulse-echo method. In this manner, the successive transmission pulses of one transducer or various transducers operated at the same time are differentiable by individual signal modulation.
