Abstract:
Ce procédé permet de déterminer une zone géographique opérationnelle (ZO) par rapport à un capteur (S) configuré pour observer et mesurer la vitesse radiale d'un objet se déplaçant avec une vitesse minimum non nulle 'VT' dans une région d'intérêt (ROI). Il comporte: - une étape de simulation du positionnement dudit capteur (S). - une étape de détermination d'une première zone (A1) de la région d'intérêt constituée des points pour chacun desquels ledit objet se déplaçant en ce point à une vitesse supérieure ou égale à ladite vitesse VT et selon une direction donnée 'DT, aurait, vu dudit capteur (S), une vitesse radiale supérieure à une vitesse seuil définie pour ce point; et - la zone géographique opérationnelle (ZO) étant définie en prenant en compte l'intersection de la première zone (A1) et d'une zone (A2) de couverture du capteur.
Abstract:
The present disclosure relates to the reduction of pressure ulcers and falls with respect to patients with physical or cognitive impairments who are in bed. A control system assures that the bed and ancillary apparatus are physically set and that patient behaviors are responded to by care providers. Motion is monitored with a non-mutually exclusive portfolio of sensors, and this information is used by one or more reasoning engines. An integrated clinical workflow is informed by the patterns of movement and then the physical environment, patient interaction, and care provider workflow are controlled to reduce the incidence of falls and pressure ulcers in bed ridden patients.
Abstract:
A motion detector and a method for operating the motion detector including a radio frequency (RF) transmission circuit, an RF reception circuit, and a controller that is electrically coupled to the RF transmission circuit and the RF reception circuit. The controller is configured to control the RF transmission circuit to generate an RF signal and control the RF reception circuit to receive a reflected RF signal from a target object in a predetermined time for reception after transmission of the RF signal. The controller is further configured to control the RF reception circuit to generate a Doppler signal indicative of a distance between the target object and the motion detection system based on the reflected RF signal. The controller is further configured to adjust a sensitivity of the RF reception circuit during the predetermined time for reception and activate an indicator based on the magnitude of the Doppler signal.
Abstract:
The invention relates to a downhole calliper tool (100) for measuring distance () between the calliper tool (100) and an interface in a well, such as a petroleum well or a geothermal well. The downhole calliper tool (100) comprises: - an impulse radar system (105) (of the CTBV-type) comprising at least one impulse radar unit (110) configured for: a) transmitting electromagnetic pulses (111 ) with the impulse radar unit (110) in a direction (RD) away from the downhole calliper tool (100), and for b) receiving reflections (112) of said electromagnetic pulses (111) with the impulse radar unit (1 10), and for c) analysing said reflections (112) to determine the distance between the impulse system (105) and the interface (200). The impulse radar system (105) is designed for carrying out at least 1 distance determination per second, but preferably at least 10 distance determinations per second.
Abstract:
An approach is provided for matching vital sign information to a concurrently recorded data set (119) according to a time domain. The approach involves determining sensor information collected from one or more sensors configured to monitor one or more vital signs of one or more objects (111a, 111b) within a monitored area (107). The approach also involves processing and/or facilitating a processing of the sensor information to detect the one or more objects and to track the one or more vital signs of the one or more objects (111a, 111b) over a time domain. The approach further involves matching the one or more vital signs of the one or more objects (111a, 111b) to a concurrently recorded data set (119) based on the time domain. The approach further involves storing at least one record of the one or more vital signs matched to the concurrently recorded data set (119).
Abstract:
A radio frequency (RF) imaging device comprising a display receives a three-dimensional (3D) image that is a superposition of two or more images having different image types including at least a 3D RF image of a space disposed behind a surface. A plurality of input control devices receive a user input for manipulating the display of the 3D image. Alternatively or additionally, the radio frequency (RF) imaging device may receive a three-dimensional (3D) image that is a weighted combination of a plurality of images including a 3D RF image of a space disposed behind a surface, an infrared (IR) image of the surface, and a visible light image of the surface. A user input may specify changes to the weighted combination. In another embodiment, the RF imaging device may include an output device that produces a physical output indicating a detected type of material of an object in the space.
