Abstract: The invention provides a computer-implemented solution for controlling access to a computer-related resource such as, for example, a digital wallet. In one or more embodiments, the wallet may be implemented using a blockchain such as the Bitcoin blockchain but the invention is not limited in this regard. Use of the invention during the initial set-up of the wallet can enable subsequent operations such as wallet transactions to be handled in a secure manner over an insecure channel such as the internet. A method according to an embodiment of the invention can comprise the steps of splitting a verification element (such as a private key in an asymmetric cryptography pair) into a plurality of shares; determining a common secret at two or more nodes in a network; and using the common secret to transmit at least one share of the verification element between the two or more nodes. The shares can be split such that no share on its own is sufficient to arrive at the verification element. This means that no one party stores the entire private key, providing for enhanced security of the key. Two or more shares are required to restore the key. The shares are stored at separate locations one of which is an independent back-up or safe-storage location. If one of the other shares becomes unavailable, the share can be retrieved from back up to ensure that the key (and thus the controlled resource) is still accessible. To ensure safe transmission of the share(s), the common secret is generated at two different nodes independently of each other and then used to generate an encryption key. The encryption key can be used to encrypt at least one share of the verification element, or a message comprising it, to ensure that the share(s) are transmitted securely.

Title: Gas powered motors and vehicles powered thereby
Inventor: RILETT JOHN WALTER
IPC: F01K3/10
Filed: 1979-08-31
Abstract: A gas powered motor (33) has a reservoir (28) for liquefied gas, a supply passage from the reservoir leading through one side of a heat exchanger (29) to the motor and a container (52) holding a buffer substance in heat conductive relationship with the reservoir. The buffer substance acts to supply heat to the liquefied gas whilst undergoing a chemical, physical crystallographic or other change of state to assist in maintaining the supply of gas to the motor (33) from the reservoir (28). In order to preserve the gas supplied to the motor for re-use without the need of a container of substantial volume the motor exhaust leads to a vessel (36) containing a condensing buffer substance (37) which condenses the gas by adsorbing, persorbing or otherwise associating with the gas accompanied by a release of heat. The condensing buffer substance is in heat conductive relation with the other side of the heat exchanger (29) in the gas supply to the motor to superheat the gas supplied. The condensing buffer substance is capable of releasing the gas when subjected to reduced pressure by a pump (50) provided which may be the gas motor (33) run in reverse to extract the gas from the vessel (36) and return it to the reservoir (28). In another embodiment the condensing buffer substance comprises an isothermal heat sink provided, for example, by a concentrated salt colution.

Abstract: Disclosed in Figure 1 is a method and apparatus for a radiometric imaging system 10 for enhancing target detection, particularly in the millimeter wave frequency range. A radiometer 12 (Figure 1) which is a passive thermal receiver, detects the reflected and emitted radiation of targets 14 within a predetermined antenna/receiver beamwidth. By scanning the radiometer over a target area 14, a thermal image is created. At millimeter wave frequencies, the received emissions from the target area are highly dependent on the emissivity of the target of interest. Foliage will appear "hot" due to its high emissivity and metals will appear cold due to their low emissivities. A bistatic noise power illuminator 16 is periodically actuated to illuminate the target of interest. When the illuminator 16 is actuated, the role of emissivity is reversed, namely poorly emissive targets will generally be good reflectors which in the presence of an illuminator will appear "hot". The highly emissive targets 14 (such as foliage and dirt) which absorb most of the transmitted energy will appear almost the same as in a non-illuminated, passive image. Using a data processor 20, the intensity of the passive image is subtracted from the intensity of the illuminated, active image which thereby cancels the backgound foliage, dirt, etc. and the reflective metallic targets 14 are enhanced for readout. A CRT display, for example, produces an enhanced image of the target area 14 of interest.

Abstract: A single sampling tube is inserted into a whole blood sample contained in a sample cup, and the blood introduced into a switch-valve and a first channel without being diluted. The switch-valve has a volumetric section. In the first channel are arranged a plurality of ion-sensing electrodes, and downstream from these electrodes, a sample position sensor. The blood is led up to where the sample position sensor is located, at which point it fills the volumetric section and the ion sensing electrode channels. The sample Na<sup>+</sup>, K<sup>+</sup>, CI-, and Ca<sup>++</sup> are detected in this state. After the switch-valve switches, the flow within the volumetric section is forced towards a photometer positioned in a second channel by a reagent solution. The blood is diluted while passing through a reaction coil, during which time enzymes in the blood give rise to enzyme reactions with the reagents. The absorbance of the reaction solution is measured by the photometer.
