An endoscope light source unit for making illumination light incident on a light guide, includes a rotary aperture plate, aperture openings of different opening ratios and an auxiliary-light aperture opening of a maximum opening ratio formed in the rotary aperture plate; a rotating device; an auxiliary light; a first sensing portion and a plurality of second sensing portions formed in the rotary aperture plate in association with the auxiliary-light aperture opening and the aperture openings; a first sensor which detects the first sensing portion; a second sensor which detects the first sensing portion and detects the second sensing portions; and a controller which controls the rotary aperture plate in accordance with the first and / or second sensors. When the auxiliary light is in the retracted position, the controller drives the rotary aperture plate while the second sensor detects the first sensing portion.

A series circuit in which a first switching element and a second switching element are connected in series at both ends of an output of an input rectifier circuit for rectifying an alternating current of an alternating current power supply, a resonant circuit in which a primary winding of a transformer and a current resonant capacitor are connected in series at both ends of the first switching element or the second switching element, a rectifying and smoothing circuit for rectifying and smoothing a voltage generated across a secondary winding of the transformer during an on-period of the first switching element or the second switching element, a control circuit for alternately turning on / off the first switching element and the second switching based on a voltage from the rectifying and smoothing circuit, and a voltage detecting circuit for outputting a voltage detecting signal when a voltage at both ends of one switching element of the first switching element and the second switching element, which is turned on at a time of transmitting electric power to the rectifying and smoothing circuit, becomes equal to a predetermined voltage or more. The control circuit turns on the other switching element of the first switching element and the second switching element based on the voltage detecting signal from the voltage detecting circuit.

A device for decoupling and / or desynchronizing neural, pathologically synchronous brain activity, in which, the activities in a partial region of a brain area or a functionally associated brain area are stimulated by means of an electrode, resulting in decoupling and desynchronizing the affected neuron population from the pathological area and suppression of the symptoms in a patient. In an alternative embodiment of the device, the pathologically synchronous brain activity due to the disease is desynchronized which also leads to the symptoms being suppressed. The device has a stimulation electrode and at least one sensor which are driven by a control system in such a manner that they produce decoupling and / or desynchronization in their local environment.

A memory system permitting a number of alternative memory blocks to be made ready in order to extend the rewritable life and thereby contributing to enhanced reliability of information storage is to be provided. The memory system is provided with a nonvolatile memory having a plurality of data blocks in predetermined physical address units and a controller for controlling the nonvolatile memory in response to an access request from outside. Each of the data blocks has areas for holding a rewrite count and error check information regarding each data area. The controller, in a read operation on the nonvolatile memory, checks for any error in the area subject to the read according to error check information and, when there is any error, if the rewrite count is greater than a predetermined value, will replace the pertinent data block with another data block or if it is not greater, correct data in the data block pertaining to the error.

The invention relates to methods and systems for creating and utilizing a modular multi-coverage insurance product. The modular multi-coverage insurance product includes a set of modular state-pre-approved insurance coverages corresponding to a plurality of insurable liabilities.

To achieve a smooth distributed printing process, the printer includes a communication module, a job receiving module and a print executing module. The communication module maintains connections to perform communication using a connection-type protocol. The job receiving module receives print jobs through the connections. The number of the print jobs that can be received in parallel is M. The M is a natural number. The print executing module executes printing processes in parallel for the received print jobs. The number of connections that can be maintained simultaneously by the communication module is set to be less than the M.

A device, system and method for occluding fluid flow through an infusion set detached from a patient's body. The device includes a means for detecting loss of contact to a patient's body and activating an occlusion mechanism accordingly.

A domino SRAM is provided with active pull-up PFET devices that overwhelm “slow to write but very fast to read” cells and allow the cells to recover from timing mismatch situations. This approach allows the traditional “bit select” clamp to actively control the “local select” through “wired-or” PFET pull-up transistors. Separate read and write global “bit line” pairs allow the read and write performance to be optimized independently.

A nonvolatile semiconductor memory device includes nonvolatile memory cells each configured to store 2-bit information per memory cell, and a control circuit configured to verify with a first threshold one or more bits subjected to writing of new data and to verify with a second threshold one or more bits subjected to refreshing of existing data in a program operation that performs the writing of new data and the refreshing of existing data simultaneously with respect to the nonvolatile memory cells, the second threshold being lower than the first threshold.
