A positioning device for a robot includes an end effector, in particular a surgical end effector, which has a base and a flange to which the robot can be secured, wherein the flange is connected to the base by a kinematic system which has at least two joints. The flange can be adjusted from a first position relative to the base, in particular at least substantially on a circular path or straight line, to a second position by the kinematic system, the second position being spaced apart from the first position. An orientation means reorients the flange from a first orientation in the first position into a second orientation in the second position, the second orientation being rotated about a reference axis by at least 75 degrees, in particular relative to the first orientation, as a result of an adjustment from a first position into a second position.

20190247260 · 2019-08-15 · ·

The object of the invention is a foot portion (2a) of a medical device, such as gynecological examination bed or a birthing bed. The aim of the invention is to provide a method for moving the foot portion into the required position quickly, effectively and not limiting the actions of medical personnel. An advantage of the present invention is moving the foot portion under the rest area (1) without undesirable protrusion. Movement of the foot portion (2a) under the rest area (1) is performed around a column (5), which is attached under the side edge of a seating portion (3). Such arrangement of the column leaves free space under the rest area (1) for moving the foot portion (2a). Movement of the foot portion (2a) is performed with minimum protrusion over the borderline of the rest area (1) by means of a parallelogram. The foot portion according to the present invention may be also positioned horizontally and vertically, according to the patient's need during the procedure. For each movement, there are available separate moving mechanisms and latching mechanisms.

SYSTEMS AND METHODS FOR DETECTING AND IDENTIFYING ARCING BASED ON NUMERICAL ANALYSIS
20190222017 · 2019-07-18 ·

Method and system allowing more accurate detection and identification of unwanted arcing include novel processing of signal voltage representing recovered power-line current. In one implementation, arc-faults are detected based on numerical analysis where individual cycles of line voltage and current are observed and data collected during each cycle is processed to estimate likelihood of presence of arc-event within each individual cycle based on pre-defined number of arc-events occurring within pre-defined number of contiguous cycles. In another implementation, fast transient current spikes detection can be done by: computing difference values between consecutive line-current samples collected over a cycle, average of differences, and peak-to-peak value of line-current; comparing each difference value to average of difference; comparing each difference value to peak-to-peak value; and, based on calculation of composite of two comparisons, using thresholds to determine if arcing is present within processed cycle.
