  • Patent number: 11728109
    Abstract: A key structure includes a casing, a covering member, a pressing element, a triggering post, a switch element. The casing has an opening. The opening is covered by the covering member. The pressing element is disposed within the opening and connected with the covering member. The pressing element includes a middle part and an extension part. The triggering post is installed on the middle part of the pressing element. The triggering post is extended in the direction toward the inner position of the casing. When an external force is applied to the middle part of the pressing element, the triggering post is moved toward the switch element to push the switch element. When the external force is applied to the extension part of the pressing element, the triggering post is correspondingly moved with the pressing element in an inclined manner to push the switch element.

  • Publication number: 20230062503
    Abstract: Hierarchical structured sparse parameter pruning and processing improves runtime performance and energy efficiency of neural networks. In contrast with conventional (non-structured) pruning which allows for any distribution of the non-zero values within a matrix that achieves the desired sparsity degree (e.g., 50%) and is consequently difficult to accelerate, structured hierarchical sparsity requires each multi-element unit at the coarsest granularity of the hierarchy to be pruned to the desired sparsity degree. The global desired sparsity degree is a function of the per-level sparsity degrees. Distribution of non-zero values within each multi-element unit is constrained according to the per-level sparsity degree at the particular level of the hierarchy. Each level of the hierarchy may be associated with a hardware (e.g., logic or circuit) structure that can be enabled or disabled according to the per-level sparsity.

  • Patent number: 11404227
    Abstract: A keyboard device includes a casing and at least one supporting leg. The supporting leg includes a first supporting part, a second supporting part and a pivotal shaft. The supporting leg is pivotally coupled to an accommodation space of the casing through the pivotal shaft. The pivotal shaft is rotatable relative to the casing. Consequently, the supporting leg can be switched between a stored state and a supporting state. When the supporting leg is in the stored state, the supporting leg is accommodated within the accommodation space, and the accommodation space is covered by the first supporting part and the second supporting part. While the supporting leg is switched from the stored state to the supporting state, the first supporting part is pushed into the accommodation space in response to an external force, and the second supporting part is correspondingly moved away from the accommodation space.
