Methods and devices are provided for reducing motion artifacts when monitoring volume changes in blood vessels. Light having a first wavelength and light having a second wavelength are transmitted through a human appendage, toward the epidermis of a patient, or through tissue within the body of a patient. A portion of the light having the first wavelength and a portion of the light having the second wavelength is received. A first signal is produced based on the received portion of light having the first wavelength. A second signal is produced based on the received portion of light having the second wavelength. One of the first and second signals is subtracted from the other to produce a plethysmography signal that is representative of volume changes in blood vessels of patient tissue.

A liquid ejecting apparatus, including: a medium conveying mechanism which conveys a medium in a first direction; a head pair composed of two liquid ejecting heads respectively having liquid ejection surfaces in which liquid ejection areas are respectively formed, the two heads having respective one end portions overlapping each other as viewed in the first direction, and disposed such that the respective one end portions are adjacent to each other in the first direction; two wipers for wiping the respective ejection surfaces; and a wiper moving mechanism configured to move the two wipers in mutually opposite directions, wherein the ejection areas partly overlap each other as viewed in the first direction, wherein, when each wiper is placed by the wiper moving mechanism at a wiping start position at which each wiper does not face the corresponding ejection surface, the two wipers partly overlap each other as viewed in the first direction, and wherein, when each wiper is placed at a wiping complete position at which each wiper does not face the corresponding ejection surface, the two wipers overlap each other as viewed in a second direction perpendicular to the first direction.

An image forming apparatus includes a plurality of image bearing members configured to bear respective images, an optical writing unit configured to write the respective images on the plurality of image bearing members by deflecting a laser beam on a polygon mirror, a transfer unit configured to transfer the respective images onto an image receiving member, and a controlling unit configured to perform an adjustment of a difference in phase of respective rotation speeds between the plurality of image bearing members at a timing of one of non-image forming operations during a series of image forming operations performed by the plurality of image bearing members, the optical writing unit, and the transfer unit.

Patients which are treated with stimulants (e.g., CNS stimulants, sympathomimetic amine, or anorectic / anorexigenic), such as patients being treated for attention deficit / hyperactivity disorder or obesity, often are at risk in developing high blood pressure. Similarly, patients which are treated with analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs) over an extended period of time risk developing high blood pressure. These and other iatrogenic therapies (therapies which inadvertently cause an increase in, e.g., blood pressure) are addressed by providing the patient with one or more antihypertensive drugs, most preferably calcium channel blockers, during the treatment period. The CNS or NSAIDs can be provided separately or together with the antihypertensive drugs or as part of a combined composition. The adjunctive therapy can prevent or reduces cardiovascular disease and other complications of high blood pressure attendant with these iatrogenic therapies.

A suction pick-up head is disclosed having a soleplate supporting rows of compartments and connection devices for putting the compartments into communication with a suction device. The connection device includes partitioning ensuring that at least a portion of the compartments are connected in series or parallel relative to the suction device.
