Abstract: According to a method for road marking detection, a sensor datasets depicting a road marking (7) at a first and a second measurement instance are generated by an environmental sensor system (4) and a parameter characterizing a motion of the environmental sensor system (4) is determined. A first and a second observed state vector describing the road marking (17) at the first and the second measurement instance, respectively, are generated based on the sensor datasets. A predicted state vector for the second measurement instance is computed depending on the at least one motion parameter and the first observed state vector and a corrected state vector for the second measurement instance is generated depending on the predicted state vector and the second observed state vector.

Abstract: An isolation system with imaging or radiation therapy capability is disclosed. At least one containment barrier (14, 15, 16, 17) defines an isolation region (10). An imaging or therapy system (20) is disposed outside of the isolation region. The containment barrier includes a substantially hollow tubular extension (24, 42, 44, 124, 224, 324) protruding away from the isolation region (10). The substantially hollow tubular extension surrounds an interior volume (26) that is in fluid communication with the isolation region and is in fluid isolation from the imaging or therapy system. The substantially hollow tubular extension is made at least partially of a material providing operative communication between the imaging or therapy system and the interior volume of the substantially hollow tubular extension.

Abstract: When performing nuclear (e.g., SPECT or PET) and CT scans on a patient, a volume cone-beam CT scan is performed using a cone-beam CT X-ray source (20) and an offset flat panel X-ray detector (22). A field of view of the X-ray source overlaps a field of view of two nuclear detector heads (18), and the offset of the X-ray detector (22) minimizes interference with nuclear detector head movement about a rotatable gantry (16). Additionally, a locking mechanism (80) provides automatically locking of the X-ray detector (22) in each of a stowed and operation position, improving safety and CT image quality.

Abstract: The invention relates to a distance measuring instrument for pedicle screws which detects the spacing between two pedicle screws (3, 3?) with the ends (26, 27) of two crossing limbs (11, 12) and displays it on a crossbar (25) fixedly connected to one of the limbs at a scale (22). Since the second limb (12) is divided into a pointer (16a) and into a flexural spring extending parallel to it at which a pronounced thumb grip (21a) is fastened, and since the thumb grip is connected to a scale (24) via which a pre-determined pre-tension can be read off relative to the pointer (16a), a spacing measurement can take place under a controlled pre-tension.

Abstract: The pressure cooker has a pot (2) with a base and a side wall and an upper rim (6). A lid (3) can be connected to the pot (2) in a sealed manner along the abovementioned upper rim (6). In the presence of a predetermined positive pressure, a locking device (12) connects the lid (3) to the pot in a non-releasable manner in conjunction with a pressure element (11) arranged on the lid (3). The locking device (12), in a fitting (5) of the lid (3), has a rocker (12a) which is mounted in a movable manner and, for control purposes and in order to lock the lid (3), interacts with the pot (2) and the abovementioned pressure element (11). Locking takes place automatically when the pressure cooker is closed and the locking means can be produced in a reliable and cost-effective manner.

Abstract: A telescopic table system (32) is used for imaging a subject in at least a first modality (12) and a second modality (14). The first modality is disposed adjacent to the second modality to align a subject receiving bore (24) of the first modality with a subject receiving bore (36) of the second modality. The telescoping table system (32) includes a base (108), an intermediate pallet (78) and a subject pallet (82) on which a subject is loaded prior to imaging. The subject pallet (82) is mounted and supported to retain a constant cantilevering with respect to the intermediate pallet (78) at all longitude positions to prevent deflection changes while extending into any of the imaging modalities. The subject pallet (82) is moved through the first modality subject receiving bore (24) for imaging in the first modality. The subject pallet (82) is withdrawn from the first modality (12) and aligned with the intermediate pallet (78).
