Abstract: A brake device and a winch having the same are provided. The brake device includes a brake sleeve, a torsion spring, a sealing member and a braking assembly. The torsion spring is fitted over the braking assembly, and the brake sleeve is fitted over the torsion spring. The braking assembly is configured to drive the torsion spring to move between an expanded position and a retracted position, so as to lock and release the brake sleeve. The sealing member is arranged between the brake sleeve and the braking assembly, so that a sealing cavity is defined between the brake sleeve and the braking assembly.

Abstract: The present application provides a compound of general formula (I), capable of being used for an organic electroluminescent device as a guest material of a light-emitting layer. The compound contains a structure in which a natural heterocyclic ring coordinates with iridium (Ir), and a light-emitting wavelength of the compound can be effectively regulated. Using the compound as the guest material of the light-emitting layer facilitates the improvement of luminous efficiency and light stability of the organic electroluminescent device. In addition, the compound provided by the present application has a small molecular weight, is applied to a light-emitting layer, has a low evaporation temperature, and facilitates processing. The present application also provides a guest material of a light-emitting layer containing the compound of general formula (I), an organic electroluminescent device, and a display device.

Abstract: A system, in one embodiment, includes a cable modem termination system configured to perform at least the following processing: determining a first quantity related to uncorrectable erroneous codewords and a second quantity related to other codewords except the erroneous codewords in the data packet received by the cable modem termination system from the terminal device via the channel; calculating a first metric relating the first quantity to the second quantity; and in response to the first metric exceeding a first threshold for a first predetermined time, determining the channel as a damaged channel.

Abstract: The present disclosure relates to a method, a medium, a program product, and a modem for setting modulation modes. The method includes detecting by a modem whether a modulation mode of the modem is inverted, the modem being capable of operating in a plurality of modulation modes, and each modulation mode having a different modulation order; and in response to the determination that the number of times of inversion of the modulation mode within a first predetermined time has reached a threshold, setting by the modem the modulation mode of the modem to a modulation mode other than a modulation mode with the highest modulation order in all modulation modes included in the inversion process and maintaining the set modulation mode for a second predetermined time. By the above method, the modulation mode is prevented from repeatedly inverting, thereby maintaining the downstream data throughput at a high level.

Abstract: A luminous character enclosing machine has an upper supporting plate (2) and a lower supporting plate (3) which are installed on a machine frame (1). A plate inlet and a plate outlet are formed respectively on two ends of the upper and lower supporting plates. A feeding unit, a grooving unit, an arc-curving unit, and a plate-clamping unit arranged between the two supporting plates are provided in succession from the plate inlet to the plate outlet. A grooving driving device is installed on the machine frame, and drives the grooving device to move up and down. This kind of grooving mode is a cold processing mode, heat generation during working which makes color of the stainless steel plates change is avoided, and a phenomenon of knife broken due to high speed rotation of a saw blade and the hardness of the stainless steel is prevented. The machine is simple in structure and convenient to operate.

Abstract: A system that allows multiple bundles of plesiochronous digital hierarchy (PDH) payload data streams to be synchronously trasmitted from one point to another is described. The system multiplexes multiple stages of the PDH using a single clock signal. This removes the need to perform stuffing and de-stuffing of the data streams at the various stages of the multiplexing.
