Methods for capacitance volume correction in fluid-containing expandable bodies and associated fluid pathways are disclosed. The methods may be applied in fluid delivery systems used to supply fluids to patients during radiographic imaging procedures, including angiography. The methods control delivery of fluid to a downstream process, including providing a fluid-delivery expandable body and a pressurizing element in fluid communication with the downstream process, pressurizing the expandable body by moving the pressurizing element in the expandable body to reduce volume therein, determining an over-travel distance for the pressurizing element, and ceasing movement of the pressurizing element after allowing the pressurizing element to over-travel the over-travel distance to compensate for expansion of the expandable body under pressure. The expandable body may be a syringe and the pressurizing element may be a plunger disposed within the syringe.

Sound equipment is configured to average an average value of a signal level at each predetermined frequency band of a sound signal at a different averaging time, to weight the average value calculated at a different averaging time by using an individual weighting value, to obtain a representative value based on a weighted average value, to determine a gain of a sound signal based on an obtained representative value, to correct a volume based on the corresponding gain, and to correct a volume based on the gain. The representative value is obtained by selecting the average value at which a gain becomes minimum within each weighted average value. The averaging performs at least a first averaging using the averaging time corresponding to the sound signal that the signal level changes rapidly, and a second averaging using the averaging time longer than the averaging time of the first averaging.

A satisfactory sound volume sensation from a hearing point of view can be obtained, and an effective sound volume correction operation can be obtained with an algorithm as simple as possible. Correction step 0 (correction function off, level correction value 0) to correction step 16 (level correction value—16 dB) are defined. When a first condition that is defined in such a manner as to correspond to a state in which distortion occurs is satisfied, the correction step is made to proceed by one step from the current correction step (−1 dB is added to a level correction value). When a second condition that is defined in such a manner as to correspond to a state in which distortion does not occur is satisfied, the correction step is made to return by one step from the current correction step (−1 dB is subtracted from the level correction value).

Disclosed herein is a dermal filler composition. The composition includes polymethylmethacrylate (PMMA), cross-linked dextran, hydroxypropyl methylcellulose (HPMC), and physiological saline or distilled water. The composition rapidly restores volume at application sites by injection, does not require pre-testing, such as allergic skin testing, because it does not cause severe allergic reactions, is cheap, and is not easily degraded or absorbed in the body, thus ensuring a long-lasting volume augmentation effect. Due to the characteristics described above, the composition facilitates volume correction requiring a large amount (20 cc or greater) of dermal filler such as in augmentation phalloplasty.

When the discharge volume of a specific ink is adjusted additionally to uniformly adjusting the discharge volume of a plurality of inks used for printing, a correction ratio input unit of a printer driver execution unit of a print control device receives input of a total correction ratio for correcting the discharge volume of cyan ink, magenta ink, yellow ink, and black ink, and receives input of a specific correction ratio for further correcting the discharge volume of black ink. The discharge volume correction unit sets the corrected discharge volume of cyan ink, magenta ink, and yellow ink to the product of the rated discharge volume times the total correction ratio, and sets the corrected discharge volume of black ink to the product of the rated discharge volume times a correction ratio multiple, which is the product of the total correction ratio and the specific correction ratio.
