Abstract: Methods and systems for multi-application video conferencing are described herein. A computing device may establish a communications session with a user computing device, then establish a group video call session with a group video call application. The computing device may provide, to the user computing device, video output associated with the group video call session. The computing device may receive, from the user computing device, input (e.g., video, audio, commands). The computing device may convert, based on an identity of the group video call application, the input into a format compatible with the group video call application. The computing device may then provide, to the group video call application, the converted input.

Abstract: Provided are an enclosed stirrer using intermittent resonance and a method. The enclosed stirrer comprises: two pairs of parallel tension springs (1), a fixing bracket (2), an elastic cantilever beam (3), a cantilever beam pressure clamping device (6), an eccentric motor (4), an arc-shaped cushion block (5), and an enclosed container (8). The enclosed container (8) is mounted on the fixing bracket (2) by the tension spring (1). The elastic cantilever beam (3) is installed below the enclosed container (8) and is axially parallel to the enclosed container (8). One end of the elastic cantilever beam (3) is mounted on the fixing bracket (2) as a clamping end, the other end of the elastic cantilever beam (3) is connected to the eccentric motor (4) as a movable end. The arc-shaped cushion block (5) is connected above the eccentric motor (4). The arc-shaped cushion block (5) reciprocally strikes the bottom of the enclosed container (8) during operation of the eccentric motor (4).

Abstract: Systems (100) and methods (1700) for providing a marker (102). The methods comprise forming a magnetic core (200) having a bone shape defined by two end portions (208, 212) and a center potion (210) disposed between the two end portions. The end portions each have a cross-sectional area larger than a cross-sectional area of the center portion. A coil (224) is disposed around the center portion. The coil is coupled to a passive electronic component (206) so as to form a resonator. The resonator is disposed in a housing (126) of the marker. The resonator resonates when an interrogation signal is produced by a transmitter circuit (112) located remote from and in proximity to the marker, whereby a variation in a magnetic field occurs.
