Abstract: A client device in a wireless network accesses a queue comprising Transmission Control Protocol Acknowledgement (TCP ACK) packets. At least some packets include packet descriptors with a flow identifier indicating a corresponding TCP flow, and a TCP ACK Generation Count. The device inspects a packet descriptor of a first TCP ACK packet, and identifies a first flow identifier and a first TCP ACK Generation Count. The device accesses entries in a data structure that each includes a first field and a second field respectively storing a flow identifier and a TCP ACK Generation Count. The device determines that a condition is satisfied, comprising that an entry in the data structure includes a flow identifier and a TCP ACK Generation Count matching the first flow identifier and the first TCP ACK Generation Count, respectively. In response to the determination, the device marks the first TCP ACK packet to be dropped.

Abstract: An imaging optical unit comprises a plurality of minors for imaging an object field into an image field. The imaging optical unit has an image-side numerical aperture greater than 0.55. Each mirror is configured so that it can be measured by a testing optical unit having at least one DOE with a predetermined maximum diameter for test wavefront generation. For the complete measurement of all reflection surfaces of the minors, a maximum number of DOEs of the testing optical unit and/or a maximum number of DOE test positions of the at least one DOE of the testing optical unit comes into play, which is no more than five times the number of minors in the imaging optical unit. The result is an imaging optical unit in which a testing-optical measurement remains manageable even in the case of a design with an image-side numerical aperture which is relatively large.

Abstract: An imaging optical unit comprises a plurality of mirrors for imaging an object field in an object plane into an image field in an image plane. An image-side numerical aperture is greater than 0.55. A ratio between an object/image offset and a meridional transverse direction is at least 0.5. A ratio between a working distance between the object plane and a reflection portion, closest to the object plane, of one of the mirrors and the meridional transverse dimension is at least 0.05. The working distance is at least 270 mm. This can yield an imaging optical unit, the use of which is relatively manageable in a projection exposure apparatus, such as for EUV projection lithography.

Abstract: An apparatus includes interface circuitry configured to receive data indicating a measurement signal of a radar sensor. The apparatus further includes processing circuitry configured to determine a rate at which the measurement signal crosses a predefined value based on the data and determine presence of at least one of an interference signal and a target motion in a field of view of the radar sensor based on the rate.

Abstract: Pressure-sensitive adhesives (PSAs) and tapes comprising said PSAs are provided. The PSAs comprise at least one poly(meth)acrylate and at least 40% by volume, based on a total volume of the pressure-sensitive adhesive, of a mixture of at least two fillers. The mixture of at least two fillers comprises at least one filler Fisph comprising or consisting of essentially spherical particles and the PSAs may conduct heat and/or provide electrical resistivity for electronic device or component applications.

Abstract: The invention relates to a label to be used as a security feature with a substrate layer and with an optically changeable section which can be microstructured, wherein the optically changeable section is connected to the substrate layer. Thus, the technical problem of creating a label of the type previously mentioned which is simple, reliable, and tamper-proof is solved. The substrate layer of said label is provided with at least one recess which is arranged along a line which runs slightly below the optically changeable section. The invention also relates to a packaging, in which at least one label with a container is connected to a closure having at least one recess arranged in the area between the container and the closure.

Abstract: A device for fastening a sensor to a support part comprises a sensor mount (1). The sensor mount (1) is made of sheet metal and comprises a base plate (2) as well as a counter plate (5), which is placed at a distance from the base plate (2) while being joined thereto. The area of the base plate (2) is greater than the area of the counter plate (5). Indexing means (18, 19, 20) are formed on the counter plate (5) in order to ensure, together with counter means formed on the sensor, the insertion of the sensor into the sensor mount (1) at a correct angle. This device is characterized, with a precise pre-alignment of the sensor, by having a particularly low weight.

Abstract: An optical data storage device has a number of storage strata (1, 2, 3) arranged one above the other, each of which has a reflection layer, preferably a metal layer (12, 22, 32), which, in a predetermined optical wavelength range, has an initial absorption of at least 5%, preferably at least 10%, and an initial transmission of at least 5%, preferably at least 10%, and the transmission or reflection of which can be varied selectively by thermal treatment. In a method for writing information to such an optical data storage device, the information is introduced into a respective storage stratum (1, 2, 3) by means of a writing laser (40) by local variation of the optical properties, to be precise preferably initially at the storage stratum (1) lying closest to the focusing optical system of the writing laser (40) and progressing from there from storage stratum to storage stratum, the transmission or reflection being set in a respective storage stratum (1, 2, 3) by thermal treatment (41).
