An image-taking apparatus is disclosed which enables the accuracy of re-performance determination of in-focus search control to reliably maintain an in-focus state in response to a condition change after focusing is achieved. The image-taking apparatus comprise a first detector which outputs a focus evaluation value signal and a second detector which outputs a detection signal different from the focus evaluation value signal. The image-taking apparatus comprises a controller which performs a first control for controlling drive of the focus lens such that an in-focus position of the focus lens is searched for on the basis of the focus evaluation value signal. The controller obtains shift information which represents a shift state from an in-focus state based on the detection signal from the second detector after the first control, and performs processing associated with the re-performance of the first control based on at least the shift information.

A system and method that provides controlled bilateral stimulation to a patient in response to physiological feedback to initiate and/or accelerate the onset of sleep and to maintain the sleep state after the onset of sleep. The system induces bilateral stimulation through stimulation modules that are coupled to opposite lateral sides of the patient's body. The stimulation modules stimulate the patient's body bilaterally through a sequence of stimulations that alternate from one side of the patient's body to the other with a pause between each successive stimulation. The system controls the duration of the stimulations, the intensity of the stimulations and the period of time between successive stimulations in response to feedback from physiological sensors. The sensors are coupled to the patient and provide physiological information which initiates or terminates the bilateral stimulations, and/or modifies the characteristics of the stimulations.

If it is determined that a malfunction has occurred in an electrical hydraulic pump and the hydraulic fluid is not supplied to a high hydraulic pressure supplied portion from the electrical hydraulic pump, the hydraulic fluid is supplied to the high hydraulic pressure supplied portion from a mechanical hydraulic pump that usually supplies the hydraulic fluid to a low hydraulic pressure supplied portion. In this case, the hydraulic pressure that is generated by the mechanical hydraulic pump is increased by increasing the output from the engine that drives the mechanical hydraulic pump.
