Abstract: A sensing device includes a driving unit, a magnetic transmission unit, a sensing unit, and an operating unit. The magnetic transmission unit includes a main driving wheel, and first and second driven wheels. The main driving wheel includes a main driving wheel body sleeved co-rotatably to the driving unit, a main feedback portion mounted co-rotatably on the main driving wheel body, and a main magnetic driving portion mounted co-rotatably on the main driving wheel body. The first and second driven wheels respectively include first and driven wheel bodies, first and second feedback portions that are mounted co-rotatably and respectively on the first and second driven wheel bodies, and first and second magnetic driven portions mounted co-rotatably and respectively on the first and second driven wheel bodies, and magnetically driven by the main magnetic driving portion to rotate when the main driving wheel body co-rotates with the driving unit.

Abstract: A dynamic memory control method for clusters includes at least one processor core and for cache memories each belonging to a corresponding cluster of the clusters. The dynamic memory control method includes borrowing a first portion of cache memory from a first cache memory and/or a second portion of cache memory from a second cache memory to allow the first portion and/or the second portion of cache memory to be utilized as a temporary internal RAM, and returning the first portion of cache memory to the first cache memory and/or the second portion of cache memory to the second cache memory such that each of the first portion and/or the second portion of cache memory is exclusively used by the at least one processor core of the first cluster and/or the second cluster.
