Patent EP-0081975-A2 (EP)
Inventor: MAGANIAS NICHOLAS H
IPC: A61B17/20
Filed: 1982-12-08
Abstract: Allergy testing is carried out by applying to the skin of a patient a test strip formed of a thin, flexible strip (10,10',30) of adhesive tape a portion of which carries on its adhesive side at least one skinpenetrating lance (16,16',32) carrying an allergen; pressing the test strip against the skin to cause temporary adhesion of the strip to the skin and to cause the lance to penetrate the skin to a depth less than the subcutaneous tissue thereby carrying the allergen into the skin and maintaining contact between the allergen and the thus-traumatized skin cells; and leaving the strip in place for a period of time sufficient for the patient's skin, if allergic to the allergen, to produce a visible allergic reaction. The test strip may be transparent so that the skin reaction can be observed through the strip. The strip may include a plurality of closely-spaced lances (16,16') or asingle lance (32).

Abstract: A control system and method for a power delivery system, such as in an automotive vehicle, having an engine coupled to a continuously variable ratio transmission (CVT). Totally independent control of engine and transmission enable the engine to precisely follow a desired operating characteristic, such as the ideal operating line for low fuel consumption. CVT ratio is controlled as a function of commanded desired system performance (e.g., power or torque) and measured actual system performance, such as CVT torque output, while engine fuel requirements (e.g., throttle position) are strictly a function of measured engine speed. Fuel requirements are therefore precisely adjusted in accordance with the ideal characteristics for any load placed on the engine. Appropriate controls prevent anomalous engine and vehicle behavior, and allow for transient start-up from rest.1n order to counteract the inherent tendency of the vehicle to accelerate when the accelerator pedal is released, a mechanism is provided for diminishing fuel flow to the engine by an amount proportional to the rate at which the commanded power or torque is reduced.
Patent EP-0099565-A2 (EP)
Inventor: ZIEGLER ALFRED DIPL-ING
IPC: H04B3/44
Filed: 1983-07-18
Abstract: Circuit arrangement for feeding electric loads from a device for power feeding by means of direct-current series feeding, the loads in each case being connected to a power feeding circuit via a current transformer arrangement containing at least one direct-current converter. Such circuit arrangements require special measures when loads are to be fed which have an increased power consumption during the switching-on phase. This problem is solved by the invention in that the current transformer arrangement can be varied with respect to its delivery of power to the load with time delay by means of a control device or by means of a criterion characterising the operating mode of the load. The circuit arrangement can be particularly advantageously used for power feeding regenerator repeaters with voltage transformers at the supply voltage input. <IMAGE>

Abstract: Type 0 erythrocytes are produced from certain subtypes of A erythrocytes or type AB erythrocytes by contacting the same following equilibration of a pH of 5.6 - 5.8 with an a-N-acetylgalactosaminidase, preferably obtained from an avian liver, for periods sufficient to convert the A antigen in the erythrocyte to the H antigen. Following removal of the enzyme, the erythrocyte is re-equilibrated to a pH of 7.2-7.4. As a result, there is obtained O type erythrocytes characterized by a 60 to 90 percent ATP level based on the level of ATP in naturally occurring 0 or AB erythrocytes. Beginning with certain A cells one obtains synthetic 0 erythrocytes characterized by a terminal a-fucose moiety, 0 antigenicity, and the absence of A antigenicity. Beginning with A<sub>2</sub>B erythrocytes, one obtains B erythrocytes by the same process characterized by the absence of A antigenicity, greater H antigenicity than naturally occurring A<sub>2</sub>B cells, the presence of B antigenicity and the afore-described ATP levels.

Abstract: The present invention relates to use of liquid crystal material encapsulated in a containment medium to produce a controlled colored or multi-colored output, for example, in response to the application, removal and variation in an electric field. A non-pleochroic dye may be in the containment medium itself, in the liquid crystal material itself or both, the object of the dye being to color light. Incident light impinging on the encapsulated liquid crystal material, which is mounted on, in. or with respect to a support medium, is isotropically scattered in the absence of an electric field, and using the principle of total internal reflection (or optical interference or both) a relatively large part of the isotropically scattered light in the support medium is reflected back to illuminate the scattering liquid crystal material, which isotropically scatters such light again, thus increasing the optical path through the dyed material and, therefore, the coloring of the light traveling such increased path. Light scattered back to the viewing direction out of the support medium causes the liquid crystal material to appear relatively bright and colored as compared to the background where there is no liquid crystal material or where the liquid crystal material is in parallel alignment in field-on condition, i.e. aligned with respect to an electric field, and, thus substantially transmissive. Original incident light where there is no liquid crystal material, that light which is isotropically scattered toward the back or non-viewing side of the display and within a certain cone or solid angle, and that light passing through aligned (field-on) liquid crystal material will tend not to be totally internally reflected; such light will pass through the support medium and may be absorbed by a remote black or colored material. Light amplification type of operation according to another embodiment in which the dye is a fluorescent one that fluoresces, isotropically emitting light in response to incident light (or possibly other radiation). 
     The non-pleochroic dye may be imbibed in the containment medium itself. Different color dyes may be placed at different areas of the encapsulated liquid crystal structure to achieve different color outputs. In the imbibing process water soluble dye is applied to the exposed surface of a water base containment medium of already encapsulated liquid crystal material. Humidity is applied, and the dye imbibes into a proximate area of the containment medium preferably going into solution therewith. 
     Another aspect of the invention relates to the locating of different color areas of the encapsulated liquid crystal structure close together, e.g. like the color dots or pixels of a color television picture tube. Then, by selectively scanning the respective areas, e.g. applying or not, an electric field thereto, the effect of a color image similar to that of a color television picture tube may be obtained.

Abstract: When a trigger clock is input, its leading and trailing edges are detected and first and second oscillators are started to oscillate by the leading and trailing edge detected outputs, respectively. The first and second oscillators oscillate at the same oscillation frequency, which is determined by data set in period setting means. A flip-flop is set by the output of the first oscillator and reset by the output of the second oscillator and the flip-flop output is provided as multi-clock pulses. The number of multi-clock pulses from the flip-flop is counted by a clock counter, and when it is detected by a stop detector that the clock counter has counted to a preset value, the first and second oscillators are stopped, by the detected output, from oscillation.
