An image pick-up module, especially for an endoscope, comprises an electronic image sensor, a single-piece circuit board which is electrically bonded to the image sensor, with at least one cable leading away from the circuit board being further electrically bonded to the circuit board. The circuit board has at least three sections, with a first section and a second section extending in spaced relation one to the other and obliquely or crosswise to the image sensor and a third section being arranged between the first and the second section. In order to provide for strain relief of the at least one cable, it is proposed that the image sensor be arranged on one side of the circuit board opposite the third section. In a method for assembling the image pick-up module the circuit board initially has the form of a planar board blank comprising at least three sections that can be folded along flexible connecting sections whereby the at least one cable is bonded to the board blank, whereafter the board blank is folded in such a way that a third section is located between a first section and a second section, and finally the image sensor is bonded to the circuit board at an end of the circuit board opposite the third section.

A laryngoscope includes a handle, a spatula arranged substantially transverse to the handle, and a coupling detachably fixing the spatula to the handle. An illumination light waveguide guides an illumination light signal and an image waveguide guides an image signal, both waveguides being attached to the spatula. The illumination light waveguide includes a proximal end having an illumination light entry opening, and the image waveguide includes a proximal end having an image exit opening, wherein the illumination light entry opening and the image exit opening are arranged in the area of the coupling. The handle includes, in the area of the coupling, an illumination light exit opening and an image entry opening which allow for the illumination light signal to couple into the illumination light waveguide from the handle, and for the image signal to couple out of the image waveguide. A centering element automatically aligns the image entry opening and the image exit opening precisely to each other.

The present invention describes a device for intracorporal, minimal-invasive treatment of a patient, comprising a working instrument that can be introduced into a body cavity of the patient for carrying out a treatment step, wherein a distal end of the introduced working instrument defines an intracorporal working area, and at least one image pick-up unit for picking up an image of the intracorporal working area, further comprising positioning means for orienting an optical axis of the image pick-up unit in dependency on a spatial position of the intracorporal working area, wherein the positioning means comprise a guide shaft, in which the working instrument is guided, and wherein the image pick-up unit is pivotably fixed at an intracorporal portion of the guide shaft. The positioning means have a holder pivotably fixed to the intracorporal portion of the guide shaft, the image pick-up unit being arranged at the holder in a distance from a location where the holder is linked to the guide shaft, such that the image pick-up unit is intracorporally pivotable into a working position, in which the optical axis runs angularly to a longitudinal center axis of the guide shaft and points to the longitudinal center axis.

An intelligent power management system that includes a circuit breaker containing a PLC module that spans open contacts of the circuit breaker to provide a communication path for PLC messages between communication paths on each of the line and load sides of the circuit when the contacts are open. The contacts are motorized to permit remote operation through PLC messaging. Coupled to the PLC module is a controller, which controls the opening and closing of the motorized contacts under user control or via an adaptive load management algorithm that reduces peak power consumption and adapts a set of loads to changed power supply conditions. The controller can also dynamically alter operational current and fault threshold levels on a real-time basis based upon circuit requirements or environmental conditions. The algorithm runs a state machine and also manages loads in a limited power source environment such as when loads are powered by a generator.

A data error detection method for a bit, byte or word oriented network wherein a protected data unit 46 and an associated data check unit 50 are addressed to a particular field device located on the network, 10 or 26. The data check unit 50 is derived in a particular manner either solely from the protected data unit 46 or from the protected data unit 46 and particular binary codes representing attributes of the network 10 or 26 and the field device sending the protected data unit 46. The particular configuration of the checking data unit 50 is such that the receiving field device or the host 22 can perform a bit-by-bit comparison of either the received protected data unit 46 or data check unit 50 with a protected data unit 46 or data check unit 50 derived in the particular manner by the receiving host 22 or field device 14 or 18.
摘要:
An exemplary power inverter comprises a push-pull inverter circuit that includes a transformer having a primary winding coupled to a DC bus and a secondary winding coupled to an AC bus, main power switches coupling each end of the primary winding to a DC return, and one or more supplemental power switches coupling at least one end of the primary winding to a snubber bus. The supplemental switch at a given end of the primary winding forms a buck-mode converter in combination with the primary winding and the associated free-wheeling diode at that end of the primary winding, and can be controlled by a switching controller to effect energy transfer between the snubber bus and DC bus. The switching controller can be configured to control power flow between the DC, AC, and snubber buses by controlling the common-mode and differential-mode voltages of the primary winding via main/supplemental power switch control.

A multivariable control system provides regulation for a plurality of control variables of interest based on selecting a particular one of the variables for regulation relative to a corresponding setpoint, while continuing to monitor the other variables and switching regulation control over to another one of the variables as needed to maintain all of them within their allowed ranges. The system includes one or more PID regulators that tune themselves for the particular variables selected for regulation control. In an exemplary embodiment, the control system is configured for controlling an alternative energy system, wherein it includes one or more power flow devices that control power flow between electrical energy storage devices (EESDs) and a common dc bus and/or power flow between the dc bus and an external ac electrical system.
