Patent number: 8796624Abstract: An automatic dispenser for dispensing a product stored therein includes an active IR sensor system for detecting a user. The IR system includes emitters and receivers which are mounted so that each IR emitter's active emitting portion protrudes outwardly from an outer surface of the housing and each IR receiver's active receiving portion is recessed behind that outer surface, such that the outward protrusion of the active receiving portion from the outer surface of the housing is less than the outward protrusion of the active emitting portion. The outer surface of the housing in question is preferably at the bottom of the housing next to the discharge outlet. This arrangement allows a reliable and accurate IR reception field to be obtained with a shape more suited to expected user positioning.Type: GrantFiled: January 9, 2008Date of Patent: August 5, 2014Assignee: SCA Hygiene Products ABInventors: Kin Lun Mok, King Lun Mok, Hong Ng

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: 8224480Abstract: A dispenser for dispensing a portion of sheet product stored in a dispenser, in which a dispensed sheet portion is to be removed by tearing the sheet portion from the remaining product supply. The dispenser includes a system which detects the presence of sheet product in a region of a dispensing outlet. Upon detection of a potential user, the sensing system causes dispensing of paper, on the condition that the sheet portion is regarded as having been torn off. The system includes elements for detecting a discontinuity in the sheet product.Type: GrantFiled: December 14, 2005Date of Patent: July 17, 2012Assignee: 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

Patent number: 7554084Abstract: An automatic dispenser for dispensing lengths of paper for use as hand towels, includes an IR sensor system for detecting a user. The sensor system scans at a first scanning rate and also at a second higher scanning rate. When the sensor system detects a user, it changes the scanning rate from the first to the second rate. The dispenser aims at reducing power consumption while providing improved reaction time when required to dispense paper.Type: GrantFiled: January 9, 2008Date of Patent: June 30, 2009Assignee: SCA Hygiene Products ABInventors: Kin Lun Mok, King Lung Mok, Hong Ng
