Abstract: There is provided an apparatus for detecting when a subject has exited an item of furniture which has an upper side for supporting a subject and an underside opposite to the upper side, and comprises an overhanging component that extends from the underside toward a surface on which the item of furniture is resting. The apparatus comprises a light source to illuminate an edge-feature associated with a distal edge of the overhanging component, to create a shadow of the edge-feature on a region of the surface. The apparatus further comprises a camera arranged to capture sequential images of the region of the surface; and a processing unit.

Abstract: The present invention relates to differential phase-contrast imaging, in particular to a structure of a diffraction grating, e.g. an analyzer grating and a phase grating, for X-ray differential phase-contrast imaging. In order to make better use of the X-ray radiation passing the object, a diffraction grating (14) for X-ray differential phase-contrast imaging is provided with at least one portion (24) of a first sub-area (26) and at least one portion (28) of a second sub-area (30). The first sub-area comprises a grating structure (54) with a plurality of bars (34) and gaps (36) being arranged periodically with a first grating pitch P G (38), wherein the bars are arranged such that thy change the phase and/or amplitude of an X-ray radiation and wherein the gaps are X-ray transparent. The second sub-area is X-ray transparent and wherein the at least one portion of the second sub-area provides an X-ray 1 transparent aperture (40) in the grating.

Abstract: The invention relates to a method of parallel MR imaging, wherein a reference scan is performed by means of a stimulated echo sequence including i) at least two preparation RF pulses (?) radiated toward a portion of a body (10) during a preparation period (21), and ii) one or more reading RF pulses (?) radiated toward the portion of the body (10) during an acquisition period (22) temporally subsequent to the preparation period (21). One or more FID signals (I1) and one or more stimulated echo signals (I2) are acquired during the acquisition period (22). The spatial receive and/or—if applicable—transmit4 sensitivity profiles of at least two RF coils (11, 12, 13) are derived from the acquired FID signals (I1) and/or from the acquired stimulated echo signals (I2). The parameters of the stimulated echo sequence are selected such that it is robust against susceptibility-induced artifacts. Moreover, 10 the invention relates to a MR device (1) and to a computer program for a MR device (1).

Abstract: The present invention provides a method and apparatus for configuring software resource for playing network programs. A request for downloading network programs transmitted by a user terminal to a network server includes the configuration information of software resources at the user terminal. After comparing and balancing the software resources required for playing network programs and the software resources at the user terminal, the network server transmits to the user terminal the software resource that is required for playing programs but are absent at the user terminal. The user terminal combines the received software resource with the local software resources to play the downloaded network programs. The user terminal can sufficiently configure the software resources required for playing network programs only by attachedly transmit the configuration information of software resources that the user terminal has when transmitting a request for downloading network programs.

Abstract: A fall detector includes an accelerometer for producing a time series of measurement samples representing the acceleration acting on the fall detector; a processor for estimating a vertical velocity and/or displacement of the fall detector from the measurement samples and using the estimated vertical velocity and/or displacement to determine whether the user has suffered a fall. The processor is configured to estimate a vertical velocity and/or displacement of the fall detector by estimating a corresponding time series of unit vectors representing acceleration due to gravity in the reference frame of the accelerometer from the time series of measurement samples; projecting each measurement sample onto the corresponding unit vector and subtracting acceleration due to gravity to give a series of estimates for the vertical acceleration of the fall detector; and integrating the series of estimates to give a time series of values for the vertical velocity and/or displacement of the fall detector.

Abstract: The present invention relates to a patient interface identification system for identifying a patient interface that is suited for a face (16) of a user (18), comprising: a receiving unit (12) for receiving a test picture (14) including the face (16) of the user (18); a database (22) for storing reference picture including faces of other users, wherein each reference picture is referenced to a patient interface advice; a processing unit (24) for comparing the received test picture (14) with at least a subset of said reference pictures stored in the database (22), wherein comparing said test picture (14) with said subset of reference pictures includes a comparison of image based features of the user's face (16) and the other users' faces; and a user interface (26) for communicating a patient interface advice including information related to a patient interface that is suited for the face (16) of the user (18), which patient interface advice is based on the comparison of said test picture (14) with the subset of

Abstract: An emergency lighting ballast device includes a housing; a circuit disposed within the housing and configured to receive a battery supply voltage and to process the battery supply voltage for driving one or more fluorescent lamps; and at least three ballast outputs providing at an exterior of the housing, each ballast output being directly connected to a different electrical component of the circuit than the other ballast outputs and being configured to be selectively connected to the one or more fluorescent lamps to supply power from the circuit to the one or more fluorescent lamps.

Abstract: A neonatal feeding tube (10) includes electronics and instrumentation for monitoring a neonate and for provides nourishment to the neonate. The tube (10) includes electrodes (20) for sensing ECG signals of the neonate. Thermistors (22, 24, 28, 30) are placed at various points along the tube (10) to measure the neonate's temperature at those points. Breathing effort is measured by calculating a pressure differential at two pressure ports (32, 34). Pulse and SpO2 are measured at a fiber optic window (35). The electrodes (20), a distal electrode (64) and a light source (66) aid in helping a caregiver position the tip (12) of the tube (10) correctly in the stomach of the neonate.
