A facial mask for filtering ambient air is formed from a pre-form of a multilayer flexible flat filter member of a size to extend over the mouth and nostrils of the user. The flat pre-form filter member can have an ovoid perimeter with an endless band of a hypoallergenic adhesive tape encircling a perimeter of the filter member and operable for sealing with the user's skin to prevent leakage over extended use. Portions of the adhesive tape can self-seal during a sizing step to form structural paths for maintaining a central concavity to ensure a large filtration area offset from the nostrils and mouth of the user. The flexible filter material can further include an activated carbon layer.

A marking tape for transferring information written thereon to a film when the film is exposed to x-rays. The tape is a laminate of an upper film, a radiopaque emulsion, and a lower film. The top surface of the upper film is partially coated with a writable ink, and the ink coating positioned directly over the radiopaque emulsion. Pressure exerted by the user while writing on the ink surface causes the underlying emulsion to part. When the marking tape is affixed to a film cassette, x-rays penetrate the marking tape in those areas where the emulsion has been parted, the underlying film is exposed, and the information entered on the marking tape is thereby transferred to the film. The marking tape can be made in different sizes and radiopacities that can be distinguished by color-coding the writable surface.

A continent ostomy port device has a generally planar face plate defining a selectively sealable aperture which is alignable with the opening of a stoma formed in the body of a user of the device. A closure portion is connected to the generally planar face plate adjacent to the aperture and is adapted to permit selective and repeatable covering and uncovering of the aperture in the generally planar face plate. A catheter portion extends from one side of the face plate and extends proximally, and one end of the catheter portion is disposed interior of the user's body, within the ostomy site, when the port device is in normal use position. The catheter portion has continuous and generally cylindrical exterior and interior side walls, the latter defining a major lumen. The catheter portion is sized and shaped appropriately for non-surgical insertion through a stoma to a sufficient distance that the presence of the catheter portion within the stoma provides a physical barrier which reduces the incidence of stoma prolapse, without the use of extraneous, externally applied materials or additional surgery. A removable cartridge is sized and shaped to fit snugly and slideably within the major lumen of the catheter portion of the device so as to be liquid-tight and to thereby prevent inadvertent escape of body waste material from the stoma through the device when the cartridge is in place, so that the user is not required to wear an ostomy bag, and to further thereby clean the interior side wall of the catheter portion as the cartridge is pressed into the major lumen of the catheter. A selectively operable anti-reflux valve that is attached internally of the proximal end of the catheter portion and is activated when it is desired to prevent escape of body waste through the port device, and deactivated when it is desired to permit passage of fluid through the port device. Retaining structure is connected to the catheter, and is non-surgically, snugly fittable into the stoma, to cause the port device to be self-retaining in a normal use position within a stoma of the user, without the need for special surgery and extraneous, external fixation materials such as tape, belts, and adhesives.

A tape transport servo system and method that do not make use of tachometers and/or encoders to derive tape velocity and position are provided. The tape transport servo system and method derive velocity and position of the tape from a primary and direct manner and also a secondary or alternative manner, especially when the primary or direct manner cannot be used. The tape transport servo system and method control a tape drive and moves a tape between one reel driven by one motor to another reel driven by another motor. The tape is read by a recording head composed of data readers, data writers and a dedicated set of servo read elements. A position and a velocity of the tape are determined from a primary velocity source when the tape is being read by the head. The position and the velocity of the tape are determined from a secondary velocity source when the tape is not being read by the head. The velocity of the tape is compared to a desired programmed reference velocity for the tape. The velocity of the tape is driven to the desired programmed reference velocity if the velocity is not equal to the desired velocity. The velocity of the tape is controlled by regulating the velocity and the driving currents of the motors. The tape transport servo system comprises a digital signal processor and a servo motor control system. The servo motor control system comprises a servo logic system, sensors, PWM motor drivers, power amplifiers, DACs, counters, computation systems, and a timing-based servo pattern monitoring system.

When heat or UV radiation is applied to an adhesive tape (130) which bonds a semiconductor wafer (110) to a carrier (120), the appropriate lift-off time for separating the wafer from the carrier is determined by monitoring the thickness (T or ΔT) of the wafer/tape/carrier sandwich. When the thickness or the thickness change has reached a predefined value or range of values, independently moveable driving members (510R) drive the wafer or the carrier with small forces at a plurality of spaced-apart locations along the periphery. As a result, the lift-off is initiated at the location of the weakest adhesion.
