  • Publication number: 20190140235
    Abstract: A system comprising one or more battery modules mounted in a rack assembly has a structure which defines a cooling air pathway for flowing cooling air across the side and/or bottom of each battery module thereby cooling the battery module, or alternatively, across the energy calls in the battery module. Further, the system has a structure which defines a thermal runaway gas pathway for flowing thermal runaway gases from a battery module out of the system. The system structure is configured to ensure that the cooling air pathway and thermal runaway gas pathway are physically separated, thereby minimizing the risk of the thermal runaway gas substantially mixing with cooling air thereby potentially resulting in a spontaneous ignition and an explosion.

  • Publication number: 20080005843
    Abstract: A body support such as a cushion, mattress, chair or the like has at least one inflatable air chamber. A pressure sensor senses interface pressures at different locations on a surface of the air chamber. Indicators derived from the interface pressures indicate the onset of a trend toward bottoming out. A controller controls air pressure within the air chamber based at least in part on values of the indicators. The controller may be implemented as a state machine.

  • Publication number: 20060152378
    Abstract: The invention provides a bed occupant monitoring system comprising a pressure sensitive member attached to a support member for supporting a bed occupant, the pressure sensitive member comprising a plurality of pressure sensors. Each of the pressure sensors is configured to provide a reflected wave energy pressure signal by reflecting incident wave energy with an intensity which varies with a pressure applied to the sensor. A pair of fibres are coupled to each pressure sensor, each pair of fibres comprising an input fibre and an output fibre. The fibres are coupled to interface electronics comprising a wave energy source coupled to the input fibre of each of the pairs of fibres for providing the applied light energy, and, a wave energy detector coupled to the output fibre of each of the pairs of fibres for converting the scattered light energy into an electrical signal.

  • Publication number: 20060096392
    Abstract: An input device has a flexible surface on which are formed deflection sensors. The flexible surface can be deformed against an adjacent resilient layer. The deflection sensors detect the deflection of the surface. Electronic circuits for processing signals from the deflection sensors to yield information regarding the locations and magnitudes of forces deflecting the surface may be deposited all, or in part on the flexible surface. The input device may be combined with a display to yield a touch-sensitive display suitable for use in a wide range of applications.

  • Publication number: 20050084138
    Abstract: A method for verifying the identity of a person comprises providing a plurality of pressure transducers and deriving a key from pressures measured by the pressure transducers when a person presses a hand (or other body part) against the pressure transducers. The key can be compared to a previously stored reference key. Apparatus for verifying the identity of a person may have an array of pressure transducers coupled to a controller. The controller produces the key and compares it to a reference key.
