Abstract: The present disclosure relates to a method for choosing the branch values for a k-ary tree. The method comprises obtaining a statistically significant sample of an input stream to be encoded, encoding the input stream using a first set of k-ary branch values, encoding it using a second set of k-ary branch values, determining that an amount of energy used to encode it using the first set of values is lower than an amount of energy used to encode it using the second set, selecting the first set based at least in part on the determination that the amount of energy used to encode using the first set of values is lower than the amount of energy used to encode using the second set of values, and constructing a k-ary tree based on the first set of k-ary branch values for use in an encoder of a physiological monitoring system.

Abstract: A stream of digital data containing an unknown word is compared bit by bit with a stored known word. The bit comparisons are counted in such a manner that the maximum output identifies the known word in the data stream. Alternatively, the non-comparing bits may be counted so that a minimum output identifies the known word.

Abstract: A retaining member (10) for retaining cylindrical members, such as rods and wires, has a base (13) and a pair of cantilevered dual action beams (11, 12) extending from the base, the beams having parallel opposed spaced apart inner edges (14), each beam having an upper and a lower portion (11a, 12a, 11b, 12b), the lower portion (11a, 12a) having an upwardly and inwardly inclined outer edge (16a, 16b) and the upper part (11b, 12b) having an upwardly and outwardly inclined outer edge (17a, 17b), the conjunction of the two portions forming a neck (18), and an entrance portion defined by a downwardly and inwardly inclined upper edge (19) on each beam (11, 12), the upper edges merging with the inner edges by a radius (20). Insertion of a cylindrical member (26) deforms the upper portions (11b, 12b) to a large extent the portions bending about the necks (18). The lower portions (11a, 12a) are deformed to a lesser extent and have substantially uniform stress distribution. The members (10) are particularly useful as contacts for insulation conductors, the insulation (27) being crushed and during passage between the upper portions (11b, 12b) of the beams (11, 12) and removed on passage past the necks (18). The conductor (26) is deformed while being pushed down between the upper portions (11b, 12b) and past the necks (18), to give a highly effective connection.

Abstract: A method and apparatus for electromagnetic hydrocarbon exploration which is accomplished by implanting at least two pairs of electrodes into the ground. One pair transmits a signal into the earth, and the other pair receives the signal.' With proper processing the polarization and resistivity of the ground can be calculated. The components are arranged in a manner to insure that the electromagnetic coupling can be determined and can be removed from the measurements. Electrode spacing can be varied to focus on the anomalous stratum. If an anomalous stratum is discovered, it is cored to determine the nature of the material creating the anomaly.

Abstract: For operating a television set in dependence on coins, the use of a memory module is proposed which can be fed with various time units in dependence on the money expended and makes it possible to call up the time units stored in the storage module individually by operating a key and to transfer these units into a control unit for the television set so that the television set can be operated proportionally to the time unit. In addition, the control over the storage module can be switched off by means of a superimposed pilot tone so that the television set can also be operated without control by the time units transferred. <IMAGE>

Abstract: A blood extraction device is disclosed herein, which is an improvement over similar devices having a cylindrical extraction tube enclosing an air-tight piston and sealed with a closure cap having an axial projection which contains a self-sealing puncturable plug and is received within a movable tubular guide sleeve containing a double-ended cannula the rear end of which is enclosed by a deformable but resilient thin hose with a closed self-sealing rear end. The improvement resides in the inclusion of one or more slots on the guide sleeve and cooperating lugs on the projection, or vice versa, each slot having an axially extending portion and a peripherally extending portion, such that rotation of the rear cutting edge of the cannula is prevented during penetration of both the rear end of the hose and the plug, and rotation is possible only when penetration is complete. In this way, the self-sealing properties of both the hose and the plug are retained, and the resilience of the hose secures each lug in position in the peripherally extending portion of each slot.

Abstract: There is provided a method of increasing the toughness of a fibre-reinforced composite material. The fibre 10 and matrix 14 material are so selected that, upon development in the matrix 14 of a crack 12 bridged by a fibre 10, the grip of the matrix 14 on the fibre 10 due to matrix shrinkage will be small enough to allow the fibre 10, while stretching, to progressively shrink away from the matrix 14 beginning at the crack 12, but large enough to cause the fibre 10 to break when the progressive fibre shrinkage reaches a major flaw 16 in the fibre 10. This is effectively accomplished by making the fibre Poisson's shrinkage at breaking stress substantially the same as the matrix contraction strain. The latter can be adjusted by mixing with the basic matrix material a selected quantity of an additional substance, such as spiro polymer or an inert particulate material.

Abstract: The present invention concerns an unique laser radiometer capable of accurately measuring the radiation temperature of a radiant surface and independently measuring the surface's emissivity. A narrow-band radiometer is combined with a laser reflectometer to measure concurrently radiance and emissivity of a remote, hot surface. Together, radiance and emissivity yield the true surface temperature of the remote target. A narrow receiver bandwidth is attained by one of two methods; (a) heterodyne detection or (b) optical filtering. A direct measurement of emissivity is used to adjust the value obtained for the thermal radiation signal to substantially enhance the accuracy of the temperature measurement for a given subject surface. The technique provides substantially high detection sensitivity over a very narrow spectral bandwidth.

Abstract: !@ A method and apparatus for shoring a trench. 
     The trench shoring apparatus carries a plurality of sheet members movable vertically relative to said apparatus by driving means forming part of the apparatus which carries pre-formed horizontal waling frame carried by and movable relative to the apparatus. 
     The horizontal waling frame is positionable between the sheet members after the sheet members have been driven by said driving means, so that an upward or downward pressure applied to said waling frame is converted, through the intermediary of said waling frame, into a lateral pressure onto the trench sides, so that the sheet members may be caused to move downwardly or upwardly by increasing the resistance to upward or downward movement of the apparatus. Similarly, a downward pressure applied to means supporting said waling frame, is converted into a lateral pressure, through the intermediary of said waling frame, so as to cause upward movement of said apparatus.
