Abstract: A contactless display system enables a user to interact with a displayed image by moving a finger, or pointer, toward a selected portion of the image. Images can be enlarged, or translated dynamically in response to detected movement. Operational methodology can be manually switched between contact-type and contactless operation to enhance flexibility.

Abstract: A plurality of directional sounders located in a region being monitored can be synchronously and sequentially activated in various patterns to establish an audibly defined exit route from the region. Emitted audio, from a respective sounder, can be different than the audio emitted by other activated sounders to provide a path and direction for evacuation to individuals in the vicinity of the exit route.

Abstract: A method, system and computer program product for automatically rendering information on a display screen of a building information system. Following generation of a plan image, such as a floor or site plan image, the plan image is modified and subsequently rendered on the display screen. The plan image is modified by adjusting the contrast ratio of the plan image such that, when graphical elements, such as icons representing elevators, evacuation stairways and fire hydrants, are rendered on the display screen overlaying the modified plan image, the graphical elements are visually distinct from the modified plan image.

Abstract: A method of controlling a cursor displayed on a display device is provided. A three-dimensional environment is displayed on a display device. A cursor and a plurality of objects are displayed on the display device within the three-dimensional environment. The cursor comprises a zone defining a volume to identify at least one object that is at least partially located within the volume. The size of the volumetric activation zone is dynamically adjusted so that a predetermined constraint is satisfied.

Abstract: Systems and methods are disclosed to display compass-type indicia relative to a three dimensional computer generated image of a building or a region. Such images, presented on multi-dimensional computer driven display devices have associated therewith directional indicating indicia, such as a compass-like image, which seamlessly provide visual and spatial directional information to a viewer even as the images are being rotated or enlarged, such as by zooming into a specific space of the building or region.

Abstract: A system for providing audio-based information pertaining to a situation communicated to a first responder en route to the situation. The information may include real-time and current data of the on-going situation (e.g., a building fire). The information may be relayed to the first responder by a dispatch center, or other intermediary, or come directly from monitoring instrumentation at a location of the situation. Also, background and/or preplanned information about the location may be provided to the first responder via a handset or other device. The responder may request certain information via the handset or device in a vehicle en route with voice requests or button activation. Visual displays of information on the instrumentation may be converted to audio- or speech-based displays for the responder.

Abstract: A public address system installed in a building or other region being monitored can communicate with a regional fire detection system. Responsive to information received from the fire detection system as to developing dangerous conditions, a control unit for the public address system can adaptively create one or more evacuation routes for a region associated with a developing condition. One or more loud speakers in the region can be used to communicate a preferred evacuation route to individuals in the region. The route can be dynamically altered as the condition varies over time.

Abstract: A sensor system for determining the weight and/or position of a seat occupant, comprising at least two spaced-apart weight force sensors which provide measured weight force signals, and a control device which generates a signal characterising the weight and/or the position of a seat occupant, on the basis of the measured weight force signals, is provided, wherein the control device has a time analysis device, by means of which the time course of a measured weight force signal of at least one weight force sensor can be analysed and which provides time analysis data.

Abstract: To provide a load cell, having a force transducer for recording tensile and compressive forces that are to be determined, which can be produced more economically and, in particular, can also be handled more easily during the adjustment of the sensor arrangement than hitherto, the force transducer comprising a flectionally elastic element and a force introduction part acting on the flectionally elastic element, having a sensor arrangement for detecting a deformation of the flectionally elastic element and the transformation thereof into an electric weighing signal, and having a housing receiving the force transducer and the sensor arrangement, with a flectionally rigid wall part, on which the flectionally elastic element of the force transducer is held, it is proposed that the sensor arrangement be arranged on a separate carrier, which is held on the flectionally rigid wall part and/or a flectionally rigid base part region of the housing

Abstract: A method and computer-readable medium for modeling smoke propagation in a structure are presented, along with applications of the method. A model is provided of a multiplicity of compartments within the structure, and the presence of a fire within a compartment is determined. The energy and smoke released by the fire is estimated, and smoke flows out of the compartment are determined. Each compartment having a smoke source is analyzed, individually, for the propagation of smoke. Each compartment is assumed to have a homogenous upper smoke layer and a lower cool air layer. The analysis includes a mass and energy balance to determine the change in characteristics of the upper smoke layer, where a known pressure for the lower cool air layer is used for the balance. For multiple smoke sources into a compartment, the contributions to the mass and energy balance of each smoke source are considered additive.

Abstract: A method, system and program product for distinctively displaying selected floors with sufficient details in a three-dimensional building model includes graphical metaphors that permit a selected or highlighted floor and their respective elements to be absolutely clear and distinct from the floors immediately above and below. The graphically displayed metaphors comprise “drawers”, “wireframe”, “expansion/compression”, “projected floor”, “sliding unselected floors”, “turning the pages”, “big map-small map”, and “fisheye” graphical configurations. Such graphically displayed metaphors can be utilized to highlight a selected floor, separate it from adjacent floors, and provide a graphical effect of depicting the floor's vertical position within a building.

Abstract: A computer system is described for dynamically adapting the size of touch sensitive areas or “buttons” on touch screens in response to the motor skill level of the user. Data from sensors arrayed around a touch screen send small changes in the user's hand position, and pass this data to a filter which separates the component of the motion due to hand tremor from the intentional motion component. The information about the extent of the hand tremor can be used to either dynamically increase the size of a button as the user's hand is in motion, or to retrieve and display a fixed screen layout with appropriately large buttons.

Abstract: An adaptive evacuation system and method for providing a safety route to evacuees. Active smoke and heat detector information can be obtained from a fire panel. Routes and exits in proximity to the active detectors are assumed to be unsafe and closed for use in evacuation. Evacuation planning is accomplished with the remaining “safe” routes. The progression of fire and smoke and the time-dependent degradation of evacuation route safety associated with progression of fire and smoke can be predicted and initial classification and signaling of route safety can be performed. As the fire progresses, the initial time-dependent classifications are updated and initially safe routes are reclassified as unsafe and then evacuation directions are modified.
