  • Publication number: 20240175295
    Abstract: An electronic door lock and a method for automatically judging a locking/unlocking direction of the electronic door lock are provided. The electronic door lock includes a latch assembly, a lock body, a transmission rod, a locking detection module, a motor module and a motion detection circuit board. The transmission rod is connected with the latch assembly for controlling the latch assembly. The motion detection circuit board is electrically connected with the motor module and the locking detection module. The motion detection circuit board controls the motor module to drive the transmission rod. Consequently, a latch bolt of the latch assembly is protruded out in a first direction or a second direction. By detecting the status of the transmission rod, the locking detection module judges whether the latch bolt is protruded to a locking position.

  • Patent number: 11976990
    Abstract: A force sensing method, applied to a force sensing system comprising a plurality of force sensors and a touch sensing surface, comprising: (a) determining a first location of a first object on the touch sensing surface; (b) defining a first force sensing region according to the first location; and (c) computing a first system sensing force which the first object causes to the touch sensing surface according to the first location, and according to at least one sensor sensing force of a first part of the force sensors corresponding to the first force sensing region. The present invention also discloses a force sensing system which uses the above-mentioned force sensing method, and an efficient force sensor calibration method.

After the plural requests are transmitted to plural corresponding target devices, the controlling circuit retires the plural requests. The request sequence table contains m×n indicating units. The request sequence table contains m entry indicating rows. Each of the m entry indicating rows contains n indicating units. The request storage device includes m storage units corresponding to the m entry indicating rows in the request sequence table. The state of indicating whether one request is stored in the corresponding storage unit of the m storage units is recoded in the request sequence table.

  • 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.

  • Publication number: 20220083500
    Abstract: Accelerators are generally utilized to provide high performance and energy efficiency for tensor algorithms. Currently, an accelerator will be specifically designed around the fundamental properties of the tensor algorithm and shape it supports, and thus will exhibit sub-optimal performance when used for other tensor algorithms and shapes. The present disclosure provides a flexible accelerator for tensor workloads. The flexible accelerator can be a flexible tensor accelerator or a FPGA having a dynamically configurable inter-PE network supporting different tensor shapes and different tensor algorithms including at least a GEMM algorithm, a 2D CNN algorithm, and a 3D CNN algorithm, and/or having a flexible DPU in which a dot product length of its dot product sub-units is configurable based on a target compute throughput.

  • Patent number: 10956227
    Abstract: Examples provide two-tiered scheduling within a cluster. A coarse-grained analysis is performed on a candidate set of hosts to select a host for a virtual computing instance based on optimization of at least one resource. A host is selected based on the analysis results. The identified virtual computing instance is placed on the selected host. A fine-grained analysis is performed on a set of communication graphs for a plurality of virtual computing instances to generate a set of penalty scores. A set of communicating virtual computing instances are selected based on the set of penalty scores. A first virtual computing instance from a first host is relocated to a second host to minimize a distance between the first virtual computing instance and a second virtual computing instance. Relocating the first virtual computing instance reduces at least one penalty score for the set of communicating virtual computing instances.
