Abstract: The heat pump system and method for operating a heat pump system includes a first Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) core that is adapted to convert movement of the core into energy in response to a temperature change. A second Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) core is in fluid communication with the first core and adapted to convert movement of the second core into energy. A third Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) or elastocaloric core is in fluid communication with the first and second cores and adapted to convert movement of the third core into energy. The first core, second core and the third core are arranged in series and a control system provides waste pressure from the first core to the second core and/or third core.

Abstract: The invention provides heat pump system a Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) or elastocaloric material core positioned in a housing and adapted to absorb thermal heat and store energy in response to a first fluid inputted at a first temperature. The housing is configured to receive the fluid at the first temperature via an inlet to cause the SMA or NTE or elastocaloric material core to change state. A device is configured to apply stress on the SMA or NTE or elastocaloric core in the housing to cause the SMA or NTE or elastocaloric core to change state. A support system is configured to engage with the material in the core to prevent the material buckling when the stress is applied wherein the support system comprises a series of buckling supports positioned along at least one length of the SMA or NTE or elastocaloric material core. The support system provides a mechanical buckling support and heat transfer optimisation for fluid flow in a SMA heat pump during compression.

Abstract: The invention provides a heat pump system and method comprising a Shape-Memory Alloy (SMA) or Negative Thermal Expansion (NTE) core (2a, 2b) positioned in a housing and adapted to absorb heat and store energy in response to a first fluid inputted at a first temperature. The housing is configured to receive a second fluid via an inlet wherein a device changes pressure in the housing to cause the SMA or NTE core to change state to release the heat absorbed into the second fluid. An outlet is adapted to output the second fluid at a higher temperature than the first temperature.

Abstract: Provided is a method of documenting a medical procedure including receiving medical data captured during the medical procedure to be documented. Information indicative of an identity of at least one of a patient that is a subject of the medical procedure and a physician involved with the medical procedure is received. The medical data is stored in a non-transitory computer readable medium associated with the at least one of the patient and the physician. Access to the medical data stored on the computer readable medium is restricted, allowing the physician involved with the medical procedure to subsequently retrieve the medical data stored in the computer readable medium and view the medical data retrieved. Restricting access to the recorded medical data prevents another physician, who may not have been involved in the medical procedure, from viewing the medical data without first entering information indicative of authorization to view the medical data.

Abstract: A fluid control valve having a valve trim formed from a geo-polymer-based material so that it is capable of withstanding rapid and extreme thermal shock which can cause damage due to differential expansion of metal components. This invention uses geo-polymer-based materials which will resist damage and can be produced at lower cost with lower embodied energy than the prior art.

Abstract: This invention discloses frame profiles for building elements such as windows manufactured by the extrusion or pultrusion of fibre reinforced geopolymer. Extrusion advantageously aligns reinforcement fibres enhancing strength in a single direction. One embodiment of this invention uses cellulosic reinforcement fibre which advantageously chemically bonds to the geopolymer molecules and provides an extremely tough and strong product. The embodied energy in the cellulosic fibre will also be significantly lower than most alternative reinforcement materials.

Abstract: A method for providing post-retirement health-care benefits is provided. The method includes the steps of adopting a health reimbursement arrangement that includes a sponsor and a beneficiary, wherein the beneficiary is employed by the sponsor. A pension plan is adopted, wherein the pension plan includes an account. Funds are provided to the pension plan and the account while the beneficiary is employed by the sponsor. Funds are dispersed from the account to reimburse the beneficiary only for medical expenses. The funds are dispersed in response to determining that the beneficiary is no longer employed by the sponsor and that the medical expenses are qualified medical expenses.
