  • Patent number: 10627388
    Abstract: A method for detecting a deflection between a source module and a detection module in a scanning apparatus and configured as a sensor pair for scanning transmission measurement of sheet material being transported in a machine direction through a sensing gap formed between the source module and the detection module. The source module is arranged on a first side of the sensing gap and emits a sensing radiation or sensing energy radiation towards the sensing gap, and the detection module is arranged on a second side of the sensing gap opposite to the first side and detects the radiation from the source module and transmitted through the sensing gap. The method includes: attaching a removable blocking device to the detection module; and performing a partially-blocked scanning process during which the source module and the detection module are jointly moved in a cross direction of the scanning apparatus.

    Abstract: A method for detecting a deflection or relative deflection between a source module and a detection module in a scanning apparatus and configured as a sensor pair for scanning transmission measurement of sheet material being transported in a machine direction through a sensing gap formed between the source module and the detection module is provided. The source module is arranged on a first side of the sensing gap and emits a sensing radiation or sensing energy radiation towards the sensing gap, and the detection module is arranged on a second side of the sensing gap opposite to the first side and detects the radiation from the source module and transmitted through the sensing gap.

  • Patent number: 10357661
    Abstract: Process and device for directly medicinally treating interior tissue during or after intubation of a patient by passing medicinal radiant energy transversely through the intubation device to irradiate the internal patient tissue for promoting healing or for an antimicrobial effect. The invention is useful in conjunction with endoscopies and catherizations, such as urinary catherization, gastric and pulmonary endoscopies, and the like procedures. The process and device can also provide liquid flow and/or vision.

  • Patent number: 9636179
    Abstract: A simple surgical drape system of generally flat shape for male urology procedures that provides full isolation of top versus bottom surface by a sealing fenestration surrounding the meatus area. It is achieved by manually forming the flat drape to a tent-like shape around the penis with a fenestration aperture smaller than glans diameter, supported by and sealing to the glans tip, and then attaching a penile clamp to hold the drape. This allows a simplified safer antibacterial preparation and less chance of infection complications. The sealed design permits better management of urology liquids, and can use absorption pad on drape top side. The drape wrinkles act as a penile position stabilizer, reducing need for extended use of the one operator hand for penile support. Drape is removable with catheter in place.

  • Publication number: 20140303447
    Abstract: The invention is a simple surgical drape system for female urology procedures that provides sealed isolation of top versus bottom sides of the drape and only exposes the female urethral meatus area for the procedure. It is achieved by a combination of a drape with a fenestration, a labia spreader where the drape fenestration is attached to provide a seal, and local illumination of the meatus area integrated in the drape system for safer and easier instrument insertion. The labia spreader also frees up one of the operator's hands and provides protection for false catherization. The labia spreader can have a vaginal inserted portion for precise position fixation of the drape fenestration to the female. The drape system also provides improved liquid management made possible by the unique combination of drape and labia spreader acting as seal between the two sides of the drape.

  • Patent number: 8229486
    Abstract: A sheet making system that has two or more separated nodes one of which may be a scanner sensing head and the other of which may be a scanner end column. Each node has a wireless system and receives power from a common AC source. Each node receives events data associated with the wireless system. Each wireless system has a circuit that obtains from the common AC power source an associated events data acquisition clock that is the same for all of the wireless systems to time synchronize to each other the associated events data signals at each of the two or more nodes. A central computer may be connected to the two or more nodes. The communication between the computer and each of the two or more nodes can be wireless or by a LAN or other mechanisms.

  • Patent number: 8060234
    Abstract: There is described a method and apparatus for tracking the location of web features through a converting process, one application of which can involve tracking paper defects from a paper machine as detected by a camera system, to a winder where the sheet is wound to rolls so that the web defects can be repaired in the winder before making the rolls. The method to track web features is based on pattern identification of inherent sheet variability or defects. The apparatus involves two or more sheet property or defect monitoring web sensors arranged at the same cross directional location at different stages of the converting operation, augmented by tachometers and/or roll diameter sensors. A full automation system for drive control on the winder based on this information is preferably added to make maximum advantage of this information.

  • Patent number: 7780817
    Abstract: A method for measuring both caliper and tension of a web such as paper wound into a roll. The method may include a standard caliper sensor whose air supply is selectively modified to allow for both the measurement of caliper and tension of the web. In another embodiment two similar or identical measurement devices are installed in tandem where one device measures tension without pinching the sheet and the other device measures caliper. The sensor may include two sheet guides for providing support for tension measurement or one or both sheet guides can be eliminated by support from machinery rolls.
