A box-type substation, an energy storage power supply system, and a photovoltaic power generation system. The box-type substation includes a low-voltage cabinet, a high-voltage cabinet, a transformer, a first keychain, and a second keychain. When two circuit breakers in the low-voltage cabinet are in a switched-on state, each of the first keychain and the second keychain is locked at a corresponding circuit breaker. Therefore, when maintenance is performed on the transformer, the circuit breakers in the low-voltage cabinet are switched off first to remove the first keychain and the second keychain. Then, the first keychain and the second keychain are used together to switch off a disconnector in the high-voltage cabinet, and the first keychain and the second keychain are locked at the disconnector when the disconnector is in a switched-off state. Mechanical lock logic of the box-type substation is simple with high efficiency.

Safety plate for a harness

Various embodiments illustrated herein disclose a full body harness that includes a connector. The connector includes a first plate and a second plate, where the first plate is identical to the second plate. The first plate and the second plate includes a plurality of slits to facilitate passage of a first harness and a second harness therethrough. The first plate is rotatably coupled to the second plate such that they are rotatable with respect to each other. Such a connector automatically enables easy adjustment of the harness based on an activity of a user who is wearing the harness.

This application provides a power generation system. The power generation system may include an integration system and a power transformation system. The integration system may include a plurality of inverters and a plurality of first switches. The plurality of inverters are connected in series to the plurality of first switches in a one-to-one correspondence. Each inverter converts a direct current from a direct current power supply into an alternating current, and outputs the alternating current to a corresponding first switch. Alternating currents of the plurality of first switches from corresponding inverters are combined and output to the power generation system, and the plurality of inverters and the power transformation system are isolated from each other. The power transformation system adjusts a voltage value of the combined alternating current and outputs the voltage value to a power grid.

An apparatus and an associated method relates to a directionally polarized deceleration module (PDM) include a shuttle () fixedly coupled to a spring-biased spool () rotatable coupled to a module housing (), a dynamic braking member (DBM) () and the shuttle () configured to travel inside a channel anchored to the module housing (). A tether may be anchored on a proximal end to the spool (). As the tether is retracted, the DBM () may be pushed by an angled distal-end of the shuttle (). The DBM () may be forced between the angled distal-end of the shuttle () and an inner channel wall, providing motional resistance to the tether. As the tether is extracted, the DBM () may be pushed substantially normal to a proximal-end of the shuttle (), providing minimal motional resistance to the tether. Various PDMs may decelerate safety lanyards in one direction to substantially avoid tangling and/or damage.

The present disclosure proposes a keybed device, including: a keybed support; a keybed arranged on the keybed support; a key height limiting column arranged in one-to-one correspondence with each key in the keybed, and an end of the key height limiting column is fixed on a bottom surface of the corresponding key; a pressure detecting device arranged in one-to-one correspondence under each key height limiting column to detect a pressing strength of each key height limiting column; and a flexible support structure arranged below each key height limiting column and located on at least one side of each pressure detection device. The keybed device includes a flexible support structure, which can avoid false triggering of the Aftertouch effect. A same depth is pressed down from the flexible support structure to obtain a consistent Aftertouch effect, and the performance effect is controllable.

A display system for displaying a media stream based on a given access point includes a decoder for decoding frames of the media stream, and an evaluation unit for scoring macro blocks (MBs) of a current frame. A score of an intra-MB is defined as a predetermined value, and a score of an inter-MB is generated based on scores of MBs in previously decoded frames. A controller signals a display to skip the current frame or start to display the media stream from a qualified frame identified using the scores of the MBs of at least the current frame.

A parallel decoder for decoding compressed video picture data including inter-coded picture item data with motion vector data. A decoding module decodes picture data stored in a temporary storage. The decoding module includes an inter-prediction module that uses inter-prediction item data to decode an inter-coded picture item by referring to already decoded reference picture item data. The structure of inter-prediction item data in the temporary storage is a function of the positions of corresponding reference picture items. The decoding order of stored inter-prediction item data by the inter-prediction module is prioritized as a function of a decoding order of reference picture item data.

An encoding system for converting video data to a media stream based on a given intra-refresh rate includes an encoder for encoding the video data to frames based on the given intra-refresh rate, a decoder for reconstructing the encoded frames, and an evaluation unit for scoring macro blocks (MBs) of a current frame being decoded. A score of an intra-MB is defined as a predetermined value, and a score of an inter-MB is generated based on the scores of MBs of previous frames. A controller determines an actual refresh period based on a qualified frame identified based on the scores of the MBs of at least the current frame, and adjusts the given intra-refresh rate based on the actual refresh period.
