An electronic device (100) is provided. The electronic device (100) includes an electrophoretic display (130), a memory (120), and a central processing unit, CPU, (110). The electrophoretic display (130) has a first mode and a second mode. The memory (120) includes a first buffer (121) and a second buffer (122). The first buffer (121) stores a first bit corresponding to a first image, and the second buffer (122) stores a second bit corresponding to a second image. The CPU (110) controls the electrophoretic display (130) to update the first image using the first mode in response to a determination that the first bit in the first buffer (121) is a certain value while the electrophoretic display (130) is updating the second image using the second mode.

A system including multiple artificial intelligence, AI, agents generates test cases for a test target in multiple stages. A first AI agent uses a large multimodal model, LMM, to process a first prompt and specifications of the test target to generate respective identifiers of test plans (1110). A second AI agent uses the LMM to process a second prompt, the specifications of the test target, and an output of the first AI agent to generate an ordered list of test steps in each test plan (1120). A third AI agent uses the LMM to process a third prompt and an output of the second AI agent to expand the test plans into test cases (1130). The system verifies the output of each of the first AI agent, the second AI agent, and the third AI agent (1140), and generates a test case document according to the test cases (1150).

Techniques pertaining to coordinated multi-access point transmission in wireless communications are described. A first access point, AP, may perform a frame exchange applicable to a coordinated transmission with a second AP (1610). The coordinated transmission may include at least one of a coordinated beamforming, CoBF, and a coordinated spatial reuse, CoSR. The first AP may transmit a physical layer protocol data unit, PPDU, based on the frame exchange (1620). The frame exchange may include an invite frame transmitted by the first AP for inviting the second AP to participate in the coordinated transmission, a response frame received by the first AP from the second AP for indicating a participation in the coordinated transmission in response to the invite frame, and a trigger frame transmitted by the first AP to the second AP prior to a transmission of the PPDU. The trigger frame may include confirmed information for performing the coordinated transmission.

An audio processing circuit (106) includes at least one audio filter (110), at least one adaptive non-active noise control, non-ANC, filter (111), and a leakage detection circuit (112). The at least one audio filter (110) controls an output signal for an audio function. The at least one adaptive non-ANC filter (111) generates at least one non-anti-noise signal according to an audio playback signal. The leakage detection circuit (112) performs leakage detection according to a first input signal and a second input signal, and adjusts the at least one adaptive non-ANC filter (111) according to a leakage detection result, wherein the first input signal is indicative of noise signal signature, and the second input signal is derived from an error signal output by an error microphone (104) that picks up remnant noise resulting from the audio function.

Eine Nutenwandungsinspektionsvorrichtung 2 zur Inspektion einer Nutenwandung 8 einer Nut an einer schwer zugänglichen Stelle eines Bauteils weist ein in einer Abtastrichtung relativ zu der Nutenwandung 8 bewegliches Endoskop 10 mit Seitenblick zum Abbilden der Nutenwandung 8 auf einen matrixförmigen digitalen Bildsensor 14 auf, der mit einer Bildverarbeitungseinrichtung 20 in Datenübertragungsverbindung steht. Der Bildsensor 14 ist derart ausgebildet bzw. programmiert, dass bei einer Relativbewegung des Endoskops 10 relativ zu der Nutenwandung 8 zeitlich aufeinanderfolgend Einzelbilder 32 der Nutenwandung 8 aufgenommen werden. Der Bildsensor 14 und die Bildverarbeitungseinrichtung 20 sind derart ausgebildet bzw. programmiert, dass aus jedem Einzelbild 32 in Abtastrichtung wenigstens ein Teilbild 34 extrahiert wird und aus einer Aneinanderreihung der Teilbilder 34 ein Gesamtbild der Nutenwandung 8 generiert wird.

Die Erfindung betrifft eine Zinkenanordnung (1) eines Bodenbearbeitungsgerätes (200), umfassend: einen Zinkenstiel (3), ausgebildet als gebogene Blattfeder, wobei ein oberes Zinkenstielende (31) zur Befestigung an einem Rahmen (201) des Bodenbearbeitungsgerätes (200) ausgebildet ist, ein Schar (4) an einem unteren Zinkenstielende (32), wobei das Schar (4) durch den Boden in einer Zugrichtung (2) ziehbar ist, wobei der Zinkenstiel (3) einen S-förmigen Abschnitt aufweist, der einen oberen Bogen (33) und einen unteren Bogen (34) bildet, wobei die konvexe Seite des oberen Bogens (33) und die konkave Seite des unteren Bogens (34) in Zugrichtung (2) zeigen, eine Zusatzfeder (5), ausgebildet als gebogene Blattfeder, wobei sich die Zusatzfeder (5) von einem oberen Zusatzfederende (51) bis zu einem unteren Zusatzfederende (52) erstreckt und an der konkaven Seite des oberen Bogens (33) parallel zumindest zu einem Abschnitt des oberen Bogens (33) verläuft, wobei die Zusatzfeder (5), insbesondere das untere Zusatzfederende (51), über eine Rückprallsicherungsanordnung (6) mit dem Zinkenstiel (3) gekoppelt ist.

The present disclosure relates to a manual air control device for a gas burner including a handle (110); a handle drive shaft (120) connected to the handle (110); a first moving block (130-1) and a second moving block (130-2) coupled to the handle drive shaft (120) at positions spaced apart from each other; a first horizontal frame (150-3) connecting the first moving block (130-1) and an upper door (160); and a second horizontal frame (150-4) connecting the second moving block (130-2) and a lower door (170).
