Patent number: 8464976Abstract: A dispenser for sheet material such as paper towel, having a housing body and a housing cover. A feed mechanism in the dispenser includes a drive roller and a pressure roller forming a nip therebetween. Movement of the housing cover from a closed position towards an open position moves the pressure roller relatively away from the drive roller to open the nip. The reverse occurs during closing the cover. This allows easy access to the space between the rollers when adding a new supply of sheet material or when removing sheet material jams. A method for loading a dispenser is also included.Type: GrantFiled: December 14, 2005Date of Patent: June 18, 2013Assignee: SCA Hygiene Products ABInventors: Kin Lun Mok, King Lun Mok, Hong Ng

Patent number: 7795584Abstract: An automatic electrically powered dispenser for dispensing a product stored in the dispenser includes an active IR sensor system for detecting a user. The IR sensor system includes at least one IR emitter and at least one IR receiver. The IR sensing system is arranged to scan for the presence of a possible user at a certain scanning rate. A sensor control system supplies the active IR emitter(s) with a first current which is constant during one or more single scans and is altered to a different, second current for further scanning. The first and second currents are determined on the basis of a signal strength of the average received IR which is received by the IR receiver(s) during a number of previous single scans. In a simplified system, the average value of the most recently received IR values may be compared to a standard value set in the control system to alter the current supplied to the IR emitter(s).Type: GrantFiled: January 9, 2008Date of Patent: September 14, 2010Assignee: SCA Hygiene Products ABInventors: Kin Lun Mok, King Lun Mok, Hong Ng
