摘要:
In a tele-evaluation system, especially a tele-medicine system for centralized remote evaluation of information, particularly medical patient information and measurement data, based on one-time use articles (disposable items) that are identified with data and/or can collect measurement data, the disposable items carries an individual encoding key for encoding the data in a patient station that is linked via data line or data network to a storage station and/or evaluation-reception station. A disposable-ID is applied to or stored in the disposable item and is automatically collected at the patient station and is simultaneously transmitted unencoded, with an identifier for the patient station. The reception station has a data link to the disposable item manufacturer in order to query, using the disposable-ID, the individual key for decoding the data.

A fuel injection nozzle for a combustion engine not only has a valve for alternately opening and closing the nozzle, but also has a part which undergoes alternating stroke movement, either longitudinally or transversely. The alternating stroke movement changes the opening angle of the nozzle opening. The alternating stroke movement is in a frequency range of approximately 5 to 20 kiloHertz.

A piezo-electric control element with a monitoring system is formed of lamellae of piezo-electric material whose longitudinal direction extends in an actuation direction of the control element. The lamellae are interconnected to form at least one lamella packet and electrodes are provided for applying electric actuation voltage at opposite principal faces of the lamella. At lest one lamella of the packet has on one principal face a measuring electrode which extends over a portion of the lamella and which is opposite a cooperating electrode on an opposite principal face of the lamella. The measuring electrode has an electric terminal separately provided for measurement of displacement and/or speed, or actuating force.

A pyrodetector is disclosed which has a sharply limited directional range of detection sensitivity for the detection of a body entering into its directional range at a distance from the detector, the body having a temperature which is different from that of its environment. A concave mirror for focusing thermal radiation emanating from the body is provided and a pyroelectric sensor positioned at a focus of the mirror is also provided and formed as a flat body consisting of an electrically non-conductive material and with a pair of electrodes. A cover transmissive to the incident thermal radiation is provided for protecting the sensor element against damage and air drafts. At least one further sensor element similar to the first sensor element and with essentially the same heating time constant is also provided and arranged adjacent to the first sensor element but beyond the mirror focus. The electrode pairs of all the sensor elements are connected to an electrical evaluation circuit which forms a difference between an output signal of the first and further sensor elements. The pairs of electrodes are each terminated with an impedance such that a time constant K of a decay time of the sensor element R.sub.x .multidot.C.sub.x =K is valid for all pairs of electrodes where C.sub.x is a capacitance of the capacitor formed from a respective pair of electrodes, R.sub.x is the respective terminating impedance, and K
摘要:
A piezoelectric ultrasonic transducer is triggered by a predeflection of the transducer in a first direction with a square-wave pulse or a saw-tooth pulse which has a rapidly dropping trailing edge to effect deflection in the opposite direction, with an overshoot. At the maximum point of overshoot, an alternating triggering voltage, preferably in the form of a pulse sequence, is applied to energize and maintain the transducer in resonance oscillation.

A heater is disclosed having a PTC thermistor heating element rigidly wedged in an intermediate space of the member to be heated by use of at least one wedge-shaped member. The wedge-shaped member has a surface which is at least the size of the heating elment so an optimum heat transmission is guaranteed.

The invention relates to a bi-component filament or fibre of a fibre-forming synthetic polymer having a core/sheath structure in at least one component and having a moisture absorption of at least 1.5% at 65% relative atmospheric humidity and at a temperature of 21.degree. C. and a moisture absorption of at least 5% at 90% relative atmospheric humidity and 21.degree. C. and a water-retention-power of at least 10% as well as to a process for the production thereof.
摘要:
A remote activity controller for people is in the form of a portable appliance, including a display apparatus, an internal clock, a user ID code and memory device, and possibly with geographic position recording and with movement and other activity sensors for mobile detection and storage of personal state data for the wearer. Further, a data interface is included via which, when required, a communication link can be set up with contract partners in order to transfer data from the appliance to them, at least at times. In addition, a label communicator is included for detection of information data of measurement or therapy appliances used, including the measurement data determined by these appliances; and also the information about products, such as foodstuffs, medicaments, and network addresses of contract partners or the like, on the basis of labels which are located on or in them or are stored in a label album. Further, a connection for a personal electronic health record is included in which the relevant health data is entered on the basis of a predetermined data scheme, and instantaneous measurement values, consumption values and behavior patterns are added continually to this data, such as weight, blood pressure, temperature, heart rate, test strips and in which other chemical diagnostic values are stored, medicaments consumed, foodstuffs eaten, movement patterns or the like, with timestamps, batch numbers, test equipment types, etc.

A pasty dental material is disclosed which hardens to a high gloss polishable mass in the presence of an initiator. The mass is formed of a polymerizable bonding agent combined with an organosiloxane filler which contains units of the formula I ##STR1## and which has been subjected to an after treatment which is a condensation in an autoclave for a period of time of 1 hour to 5 days at a temperature of 60.degree. C. to 250.degree. C. under a pressure which is the sum of the partial pressures at the given temperature.

Laser-induced color printing with means with which the printing color of a micro-capsule to be impinged by the laser beam (12) is identified. These means are a fluorescence transformer material as a constituent of the content of the micro-capsules (3) or an additional white light ray with which the printing color of an individual micro-capsule (3) can likewise be identified.The printing ensues given coincidence of a printing instruction provided for a defined location with color specification and of the momentary incidence of the scanning laser beam (12) on a micro-capsule (3) for which this printing color has been identified as being present.
