Abstract: The invention addresses the problem of providing an electrically powered artificial hand that can be constructed with a simple configuration, the operation of which is easy to master and the control of which is highly reproducible. The electrically powered artificial hand (1) is provided with: a shape-detecting sensor (2) for detecting the shape of the forearm of an upper limb amputee; a hand section (6) having a pair of arms (7a, 7b) that are capable of opening and closing movements; and a main control unit body (8) having a sensor signal-receiving circuit for receiving the sensor signal output from the shape-detecting sensor (2) according to the shape of the forearm, and a control signal-generating and -sending circuit for generating a control signal on the basis of the sensor signal and sending the control signal to the hand section (6) to control the opening and closing movements of the arms (7a, 7b).

Abstract: In an electronic unit having a stack in memory and adapted to run a plurality of tasks in accordance with a multitask operating system and to save context data in the stack, a scheduling unit schedules the plurality of tasks for wakeup so as to execute the plurality of tasks. Each of the plurality of tasks stays in at least one of a suspended state, a ready state, and a running state. A measurement unit measures an amount of space to be used in the stack during the at least one of the tasks staying in neither the running state nor the ready state.

Abstract: When an execution time of a task is short the execution time of the task can be reliably specified and erroneous calculation of an execution time due to other processing can be prevented. A task designated in advance and a task whose execution is initiated are collated with each other. When the tasks are compared with each other, the initiation time of the executing task is recorded at the initiation of the executing task and the difference between the termination time and the initiation time is recorded as an execution time when the executing task terminates.
