Publication number: 20100299840Abstract: The invention refers to a sensor arrangement for weight and/or movement sensing in a bed and uses thereof, to a bed and to a method of sensing weight and/or movement of a user in a bed. For the sensing of weight, activity and/or cardiopulmonary performance in a bed, force sensors (6) integrated between a bedframe (2) and a mattress frame (3) are used. The sensors are designed in a way that they can be positioned between the mattress frame and the bedframe without significantly enhancing the height of a mattress bearing surface. Thus, the integration into any bed with bedframe can be easily realized. The measurements do not require any user interaction or even direct contact between user and sensor.Type: ApplicationFiled: May 7, 2008Publication date: December 2, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Andreas Brauers, Ralf Dorscheid, Frank Johnen

The scale provides a remote display of the weight that is easily visible while an item of luggage is resting on the rack. Additionally, the weighing surface of the scale is configured to measure the length and width of the item of luggage resting on the scale.Type: ApplicationFiled: August 11, 2006Publication date: February 14, 2008Inventors: Marie Jewett, Steve Jewett

Patent number: 7308347Abstract: A frame-based occupant weight estimation apparatus for a vehicle seat includes compliant load transfer mechanisms interposed between the seat frame and floor brackets bolted to the vehicle floor. The compliant load transfer mechanisms translate the seat loads to a central location for measurement by a set of force sensors. The load transfer mechanisms preload the force sensor to enable off-loading detection, and an overload device securely anchors the seat to the floor bracket without interfering with normal load measurement.Type: GrantFiled: July 14, 2003Date of Patent: December 11, 2007Assignee: Delphi Technologies, Inc.Inventor: Morgan D. Murphy

Patent number: 7297880Abstract: An over-travel protection device for mounting an occupant classification sensor having a deflecting member, the sensor being mounted between first and second seat mounting portions, is described. The device has a sensor plate positioned adjacent the occupant classification sensor and a spacer having a land. The spacer is positioned adjacent to the occupant classification sensor. A compliant element is located between the sensor plate and the second seat mounting portion. The land is spaced from the first mounting portion until the deflecting member deflects a predetermined amount, causing the land to abut the first seat mounting portion and thereby preventing further displacement of the deflecting member.Type: GrantFiled: September 13, 2004Date of Patent: November 20, 2007Assignee: Chrysler LLCInventors: Michael Sulkowski, Issam Al-Khairy

Patent number: 7282652Abstract: A hospital bed weighing system includes four carriage assemblies and a frame assembly. Each of the four carriage assemblies includes a wheel support member for receiving and supporting one of the four wheels of a typical hospital bed. Two caster wheels are mounted at opposite ends of each carriage assembly by a load cell. Inputs from the load cells is analyzed and displayed by a weight display unit which may be calibrated to weigh a bed occupant by subtracting out the weight of the supported bed. The four carriage assemblies are positioned relative to each other by an adjustable frame assembly which is designed to not transfer substantial loads between the carriage assemblies. Since the carriage assemblies are supported by caster wheels, a bed supported by the weighing system may be moved about substantially as if it were rolled upon its own wheels.Type: GrantFiled: May 27, 2006Date of Patent: October 16, 2007Inventors: Michael Karl Johnson, Lee Allen Reed

Patent number: 7282654Abstract: Provided herein are exemplary embodiments of a weighing device comprising a bladder and a plurality of contact switches printed on the bladder. The bladder comprises a top and a bottom sheet of a suitable non porous material. The contact switches are made by printing a conductive pattern on one side of the bladder and printing conductive elements with leads or traces on the other side of the bladder. The two sides of the bladder are heat sealed together along the periphery of the bladder with the conductive portions facing each other. An inflation port is also formed in the periphery. In operation, the bladder is placed under an individual to be weighed. Next, the bladder is inflated using a gas. Finally, monitoring circuitry coupled to the bladder measures and records the pressure at the time each of the switches open due to the separation of the conductive portions.Type: GrantFiled: June 8, 2005Date of Patent: October 16, 2007Inventors: Peter Salgo, Vern Liebmann, Michael Sturdevant

Patent number: 7261179Abstract: An occupant detection apparatus including a weight sensor and a contact prevention unit. The weight sensor is provided together with a bottom structures positioned below a seat cushion of the vehicle seat, and measures a weight of an occupant on a vehicle by measuring a load to be applied to the vehicle seat. The contact prevention unit prevents a contact between the weight sensor and an interior trim of a vehicle cabin.Type: GrantFiled: August 10, 2004Date of Patent: August 28, 2007Assignee: Honda Motor Co., Ltd.Inventors: Tetsumei Mochiduki, Makoto Nagai

Patent number: 7253366Abstract: A system for monitoring a patient on a hospital bed includes load cells and a controller for detecting patient movement on, exit from, and impending exit from the hospital bed, including movement across or outside a virtual boundary or region located on the bed. The controller is configured to detect changes in the distribution of patient weight among the load cells. The controller is also configured to accommodate the installation or removal of medical equipment or other tare weights on the bed, head incline adjustment, and bed frame deformation or other changes in the system causing redistribution of weight among the load cells, while minimizing false alarms. A caregiver may select between various patient monitoring modes and remotely monitor patient movement relative to a reference load cell distribution, impending patient exit from the bed and patient exit from the bed.Type: GrantFiled: December 10, 2004Date of Patent: August 7, 2007Assignee: Hill-Rom Services, Inc.Inventor: Aziz A.

Patent number: 7232962Abstract: A mobile hospital patient bed scale is contemplated which lifts the entire bed with patient in situ on a load platform with an aperture to accommodate the undercarriage of many hospital beds such as a motor. The scale minimizes both vertical and horizontal displacement. The platform has load cells which deliver data to a memory and display device. The invention is portable and partly foldable to aid in storage. It provides for recharging if desired, and for use of an auxiliary power source if desired. The driving force for lifting may be a hydraulic ram or an electrically powered screw drive.Type: GrantFiled: January 20, 2004Date of Patent: June 19, 2007Inventor: Richard Rynd

Patent number: 7219760Abstract: An apparatus (10) is used with a vehicle seat (2) and a vehicle floor pan (4) for supporting the vehicle seat. A sensor lever (100) transmits the load of the vehicle occupant from the vehicle seat (2) to the vehicle floor pan (4). The sensor lever (100) has a first end portion (102), a second end portion (112), and a middle portion (122) interposed between the first end portion and the second end portion. The middle portion (122) of the sensor lever (100) is movable with the vehicle seat (2). The sensor lever (100) has a first sensor portion (107) disposed between the middle portion (122) and the first end portion (102). The sensor lever (100) has a second sensor portion (109) disposed between the middle portion (122) and the second end portion (112). The first and second sensor portions (107, 109) bend as the vehicle seat (2) moves vertically relative to the vehicle floor pan (4).Type: GrantFiled: February 14, 2005Date of Patent: May 22, 2007Assignee: TRW Automotive U.S LLCInventors: George B.
