  • Patent number: 11655912
    Abstract: A diaphragm assembly for a mass flow controller is disclosed. The diaphragm assembly includes an aperture, side walls extending from the aperture and disposed about a central axis, the side walls including multiple convolutions, and a poppet including an interior surface facing the aperture and exterior sealing surface. At least a portion of the diaphragm assembly moveable extends and retracts within a control valve cavity of the mass flow controller. A push rod extending from the interior surface of the poppet moves, responsive to an actuator of the mass flow controller, to enable the exterior sealing surface of the poppet to open and close a flow path through the control valve cavity.

  • Publication number: 20200275845
    Abstract: A blood-pressure measurement apparatus according to an embodiment comprises a measurer and a blood-pressure acquirer. The measurer is configured to measure a pulse of a subject based on a received-light signal scattered in a body of the subject when a light signal in a predetermined frequency band is irradiated. The blood-pressure acquirer is configured to acquire a diastolic blood pressure based on a first value and a second value, the first value corresponding to a blood flow of the subject in a first time period in a time period from a first reference time at which a value obtained by first-order differentiation of the pulse with respect to a time becomes the maximum to a second reference time at which a next pulse rises, the second value corresponding to a vascular resistance of the subject.

  • Publication number: 20200046232
    Abstract: A blood circulation detection apparatus has a measurer to measure a pulse wave of a subject based on a received optical signal diffused in a body of the subject and received when an optical signal in a predetermined frequency band is emitted to the subject, and a blood circulation detector to detect blood circulation of the subject based on a D. C. component of the received optical signal, a blood-volume change amount of the pulse wave from a rising time of the pulse wave to a time when a first-order differentiation value of the pulse wave with time becomes maximum, and a first-order differentiation value of the blood volume change amount with time.

  • Publication number: 20190282104
    Abstract: A biological measurement device according to an embodiment includes a measurer, an evaluation value acquirer, and an output unit. The evaluation value acquirer measures a pulse wave. The evaluation value acquirer acquires, on the basis of a first index value based on an amplitude value of a speed pulse wave obtained by time-differentiating the pulse wave and a second index value correlating with a reference level of the pulse wave at each heartbeat, an evaluation value indicating heat radiation activity. The output unit configured to output information corresponding to the evaluation value.

  • Patent number: 9690355
    Abstract: According to an embodiment, a semiconductor device can be in an operating state and a standby state with a choice of a plurality of standby state levels and has a CPU, an interrupt control circuit, and a hardware control circuit. The CPU makes a comparison of a first return time period corresponding to a first standby state level that is a shallowest one selected from among allowable standby state levels set for one or more tasks executed immediately before transition to the standby state with a second return time period selected from among allowable return time periods set for the one or more tasks executed, changes a standby state level of the standby state if the first return time period is judged to be longer than the second return time period as a result of the comparison, and controls the hardware control circuit.

  • Publication number: 20110066836
    Abstract: According to one embodiment, a CPU boots a small OS having a function of executing a target application, boots the target application on the booted small OS, and boots a CPU dispatcher for switching an execution OS. The CPU boots a rich OS capable of executing applications larger in number than applications executed by the small OS by using the CPU dispatcher, in a background of the small OS, while causing the target application booted on the small OS to run. After the rich OS is booted, the CPU boots the target application on the booted OS separately from the target application running on the small OS. The CPU passes an execution state of the target application running on the small OS to the target application booted on the rich OS and shifting the execution OS from the small OS to the rich OS.
