Abstract: La présente invention propose un indicateur de niveau qui mesure le niveau dans un récipient ou la hauteur de stockage d'un matériau de remplissage sur une aire de stockage et qui comporte un transducteur ultrasonore travaillant alternativement comme transducteur d'émission pour l'envoi d'impulsions d'émission et comme transducteur de réception. Ce transducteur d'émission et de réception (31, 33, 35) est entouré par le boîtier (21) de l'indicateur de niveau et forme un entrefer (38) coaxial ayant la forme exacte d'un anneau cylindrique.

Title: Colour deformable mirror device having optical thin film interference colour coatings
Inventor: LI LI
IPC: G02B26/08
Filed: 1995-09-20
Granted: 2002-02-05
Abstract: A semiconductor device comprises a plurality of coloured deformable mirrors controllable by electrical circuitry. Groups of mirrors, responsive to the electronic signals, are selectably operable to reflect incident light. The deformable mirrors are coated with an optical thin film interference colour coating having at least a layer that is substantially transparent to the visible light. As well the optical thin filminterference colour coating includes at least one further layer that is partially absorbing with respect to the visible light. The spectral reflectance and absorptance of the deformable mirror is modified in order to obtain a desired reflectance colour by the process of optical interference enhanced absorption in the optical thin film interference colour coating. The optical thin film interference colour coating has predetermined layer thicknesses and materials; the substantially transparent layer substantially determines the desired reflected colour.

Abstract: A flushable midstream urine collector which is discardable, dissolvable, and flushable in the water of a common flush toilet without obstructing or damaging the water discharge lines of the waste water system is disclosed.  The collector includes an open-ended tubular body which defines a flow passage and a cup member which is mounted in the flow passage.  The cup member by-passes the initial and terminal portions of the urine stream when a patient voids into the collector, but the cup member collects a midstream sample which may be easily transferred from the cup member to a collection tube.  The primary structural components of the tubular body and cup member are formed from a water-soluble material which will dissolve or disperse when disposed in the water of a toilet bowl.  However, thin protective layers of water-insoluble material line the interior of the tubular body and cup member for preventing urine passing through the device from initiating premature dissolution of the primary components of the collector.  When discarded in the water of a toilet bowl, the water in the bowl envelopes the collector, initiates dissolution of the primary components of the device, and the protective layers of the device, which are relatively weak, collapse or disperse once the primary layers of the device lose their structural integrity.  Thereafter, the entire device can be flushed through the water discharge lines without obstructing or damaging the waste water system.
