Abstract:
An aerosol delivery system (e.g., MDI or nebulizer for delivering aerosolized medication to a patient) includes a temperature sensor in an aerosol output pathway of the system. A controller determines that an aerosol generator of the system has released aerosol when the sensor senses a predetermined temperature change in the pathway. The temperature sensor may also comprise a thermal flow sensor that includes a heater and upstream and downstream temperature sensors. The controller compares the upstream and downstream temperatures to determine the presence, direction, and/or magnitude of fluid flow in the pathway. The controller may use the aerosol detection and/or flow detection to monitor compliance with desired use of the system and/or provide real-time instructions to a user for proper use of the system. The controller may record the aerosolization and flow data for later analysis.
Abstract:
A method of forming a spectral purity filter having a plurality of apertures configured to transmit extreme ultraviolet radiation and suppress transmission of a second type of radiation, in which trenches are formed in a base material in a pattern corresponding to the walls to be formed between the apertures. The trenches are filled with a grid material to form walls of the grid material, and the base material is selectively removed until the grid material is exposed and forms the spaces between the walls of the grid material for the apertures.

Abstract:
The invention relates to a sensor (102, 202, 402, 502) for detecting bubbles in gas phase present in a liquid (208, 408, 527) flowing through a flow path (204, 406, 508). The sensor comprises a heating element (106, 210) for heating the liquid, which heating element is provided with a predetermined level of power at least during detecting, and a transducer arrangement (108, 112, 212) arranged for generating a measurement signal (114) indicative for the temperature of the heating element. The sensor furthermore comprises a comparator arrangement (116) for comparing a measurement value of the measurement signal with a predetermined threshold level, which predetermined threshold level corresponds to a reference temperature attainable by the heating element in response to said predetermined level of power and a minimum velocity attainable by the liquid in the flow path. Based on the latter comparison, the comparator arrangement generates an output signal (118) indicative for a possible presence of bubbles in gas phase.

The assembly (100) comprises a laterally limited semiconductor substrate region (15) in which an electrical element (20) is defined. Thereon, an interconnect structure (21) is present. This is provided, at its first side (101) with contact pads (25,26) for coupling to an electric device (30), and at its second side (102) with connections (20) to the electrical element (11). Terminals (52,53) are present at the second side (102) of the interconnect structure (21), and coupled to the interconnect structure (21) through extensions (22,23) that are laterally displaced and isolated from the semiconductor substrate region (15). An electric device (30) is assembled to the first side (101) of the interconnect structure (21), and an encapsulation (40) extending on the first side (101) of the interconnect structure (21) so as to support it and encapsulating the electric device (30) is present.
Abstract:
The present invention relates to a method of controlling the output of a luminaire comprising an array of LEDs emitting light of at least one color. The array has single color LED groups, wherein each group consists of at least one LED. The method comprises the following steps for each LED group:spectrally filtering the light emitted by the LED group by means of a first filter as well as by means of a second filter; detecting the spectrally filtered light from said first and said second filter and generating respective first and second response signals, wherein the levels of said first and second response signals are related to the respective amounts of detected spectrally filtered light; and controlling the light output of said LED group on the basis of said first and second response signals, wherein the filter characteristics of said first and said second filter are at least partly non-overlapping. The invention also relates to a corresponding control system for performing the method.
Abstract:
The present invention relates to a system-in-package that comprises an integration substrate with a thickness of less than 100 micrometer and a plurality of through-substrate vias, which have an aspect ratio larger than 5. A first chip is attached to the integration substrate and arranged between the integration substrate and a support, which is suitable for mechanically supporting the integration substrate during processing and handling. The system-in-package can be fabricated according to the invention without a through-substrate-hole etching step. The large aspect ratio implies reduced lateral extensions, which allow increasing the integration density and decreasing lead inductances.
Abstract:
A local power-delivery/data-reception unit is installed within an insertion end of a sealed catheter. The local power-delivery/data-reception unit wirelessly powers a separately sealed sensor that is attached to the insertion end and configured for wirelessly sending a data signal to the local power-delivery/data-reception unit. The catheter may further feature a remote power-delivery/data-reception unit disposed within the handle and configured for wirelessly communicating with the local power-delivery/data-reception unit and a controller for controlling the sensor.
