Abstract: The present disclosure relates to a wireless listening device, which includes a housing adapted to be wearable and a top cover. The top cover closes the housing at an end of the device and is provided with a central bumped portion that includes: a substantially planar panel portion; and a raised portion, which is connected around an outer periphery of the panel portion and at least partially extends toward the housing in a direction perpendicular to a plane where the panel portion is located. The panel portion and the raised portion form an accommodating groove that at least partially accommodate a charging device, a manipulation device and an antenna. In the plane where the panel portion is located, a diameter of a minimum circumscribed circle of orthographic projections of the charging device, the manipulation device, and the antenna as a whole is in a range of 8 to 16 mm.

Abstract: A precursor compound of a radiolabeled compound as shown in Formula (I), a radiolabeled compound thereof, or a pharmaceutically acceptable salt thereof. The radiolabeled compound is high in water solubility, good in in-vitro stability at room temperature, and high in plasma protein binding rate, and shows high and long-time bone uptake in both in-vivo distribution in mice and imaging of New Zealand rabbits, and animal experiments show that the development effect is better than that of 99mTc-MDP.

Abstract: The present disclosure relates to a customized wireless earphone, which includes a panel assembly and a customized housing. The panel assembly includes a panel, a mainboard, a manipulation device, a charging device, a battery, an antenna device, a sound pickup device, a speaker assembly, and a wireless communication module. The mainboard, the manipulation device, the charging device, the battery, the antenna device, the sound pickup device, the speaker assembly, and the wireless communication module are located in a space formed by the panel and the customized housing.

Abstract: The present disclosure relates to an in-ear wearable device and a panel assembly thereof. The panel assembly of the in-ear wearable device includes a panel, a mainboard, a manipulation device, a charging device, a battery, an antenna device, a sound pickup device, a speaker assembly, and a wireless communication module. In a plane perpendicular to the panel or the manipulation device, an orthographic projection of the manipulation device partially overlaps an orthographic projection of the charging device; in a plane where the panel or the manipulation device is located, minimum circumscribed circles of the orthographic projections of the manipulation device and the charging device at least partially overlap each other.

Abstract: A method and apparatus for a smartly controlled dual-cuff endotracheal tube. A fully automatic or manual closed-negative-feedback loop control logic inflates/deflates a dual-cuff mechanism inside a patient's trachea. Separate inflating and deflating units with independent air control functions control the pressure based on signals from the cuff pressure control system. The dual-cuff mechanism comprises an inner and outer cuff connected to pilot balloons with individual pressure sensors to measure pressure and send data to the control system to calculate the delta. The inner cuff has an opening that serves as a pressure equilibrium indicator for the optimal cuff pressure being achieved. The apparatus can be manufactured to be a disposable product after a single use. The disclosure achieves: increased control and ease of use; increased accuracy, range, and control of pressurized airflow; an improved way of determining ideal cuff pressures in real-time; improved hygiene; and decreased costs.

Abstract: A router for transferring data packets between external devices. The router comprises: 1) a switch fabric; and 2) R routing nodes coupled to the switch fabric. Each routing node exchanges data packets with the external devices and with other routing nodes via the switch fabric. A first routing node comprises: i) an inbound network processor comprising a first plurality of microengines capable of forwarding incoming data packets from external ports to the switch fabric; ii) an outbound network processor comprising a second plurality of microengines capable of forwarding outgoing data packets from the switch fabric to the external ports; and iii) an asynchronous variables circuit for controlling access of the inbound and outbound network processors to at least one of i) a shared resource and ii) a shared variable in the router.

Abstract: A method for switching frames in a switching system is provided. The method includes receiving a first stripe set for a first port at a second port. The first stripe set is stored in a particular location in a queue of the second port. A determination is made regarding whether a first full flag associated with the first port has been set. If the first full flag has not been set, the first full flag is set and the particular location in the queue of the second port is provided to the first port.

Abstract: A method for processing frames in a switching system is provided. The method includes performing a data striping technique on an incoming high data rate (HDR) data stream having a high data rate to generate a plurality of lower data rate (LDR) stripes having a lower data rate than the high data rate. The plurality of LDR stripes is processed using processing techniques associated with the lower data rate. The processed LDR stripes are multiplexed into a single, outgoing HDR data stream.
