Abstract: A response form containing a means of input that on manual influence can switch a conducting electrical circuit connected to an electronic unit (40) incorporated into the response form for registration of the said influence. The present invention provides such a response form at low cost and enables the use of the response form as a patient journal. The patient journal also can be integrated with a pharmaceutical response package. The response package is formed of a disposable material in the form of a sheet (12), and a conducting circuit (26) is printed onto one side (16) of the disposable material. The means of input can consist of circuit makers (30, 32) that are visually marked-on one side of the disposable material and that are arranged to make electrical contact across an interrupted loop (28) of the conducting circuit (26) upon pressing together localized inner surfaces (14, 16) of the disposable material which face each other. The means of input also may consist of circuit breakers that are visually marked on pieces of the disposable material and arranged to cause electrical interruption in a loop of the conducting circuit when these pieces are at least partially removed from the response form.

Abstract: A data processing method and apparatus are proposed for used in the encryption, decryption and authentification of messages. A memory for storing input information, a set of operations and a processor for executing the operations on the stored input information are provided. The input information is utilised to select the order and number of operations performed. The operations are devised such that any possible input string will be interpreted as a valid program and the memory is extensible. Furthermore, data is output as a function of the input information. As a result the state of the memory generated during execution is indeterminate prior to execution and the process evolves differently for each possible input string. Accordingly, the process performed by the module cannot be described by an algorithm. The method and apparatus according to the invention have a number of different applications particularly in the field of cryptography including a random number generator, a one way hash function generator or as a key generator for a cipher primitive in encryption and decryption.

Inventor: HELLSTEN HANS
IPC: G01S13/90
Filed: 1998-12-18
Abstract: The present invention relates to a radar system which comprises a platform which moves over a number of objects. The number of objects can be very large and the objects can appear in the form of, for example, a ground surface. The platform supports radar equipment which reproduces the objects by means of synthetic aperture technique (SAR) via at least one antenna without requirements as to directivity or fractional bandwidth. Moreover, the movement of the platform is, during the recording of data for a SAR image, essentially rectilinear and uniform. The invention is characterized mainly in that it comprises a signal-processing device which records received radar echoes from each transmitted radar pulse and records or calculates the position of the used antenna or antennae, and which calculates a one-parameter quantity of two-dimensional SAR images as a function of two image co-ordinates where the parameter is the relative speed. Here use is made of the fact that each object, i.e. a radar echo with certain image co-ordinates, is reproduced at a maximum ratio of desired to undesired signal for a predetermined value of the relative speed parameter, which value is established to be the magnitude of the relative velocity vector between the object and the platform. In the calculation, the signal-processing device backprojects radar raw data in a hierarchical scheme, where each level is based only on the immediately preceding one, and where the summation of radar raw data occurs in the form of subapertures having a gradually increasing length.

Abstract: The spray mat has a plate (1) which is made from a soft material with several holes (1a) in it of various geometries. At the foot end, there is a location (1b) for the central distributor switch (4). A head cushion (5) has a hoop (6a) on the back of it for the users hand. The outlet units (2) are pressed into the holes in the plate and have a sucker underneath them. In the outlet units is a flexible fleece-like material insert. The spray characteristics are determined by the compressed air passing through the fleece. Due to their elasticity, the fibres of the fleece are tightly packed when low pressure is being used but with high pressure they become loose. With low air pressure therefore, a fine spray is produced but with high pressure, a coarse massage spray is produced.
