Title: Waste water heat recovery unit
Inventor: KEIRNAN RICHARD
IPC: F28F1/06
Filed: 2013-07-22
Abstract: The heat exchanger comprises a primary tube arranged to receive a first fluid and a plurality of secondary tubes arranged to receive a second fluid. The primary tube is fluted. The secondary tubes are received in respective flute channels of the primary tube to facilitate conductive thermal transfer of energy between the first and second fluids. The heat exchanger is particularly suitable for use in recovery of thermal energy from waste water of a shower, whereby the waste water can be passed through the primary tube and mains cold water passed through the secondary tubes before being sent to a mixer valve of the shower, thereby requiring less hot water to be mixed to provide a shower of the same temperature. The secondary tubes may be provided on a manifold (figure 2A) that fits onto the primary tube (figure 1A). When arranged vertically, the primary tube may be helical (figure 1B) to slow the descent of warm waste water to ensure sufficient time for heat transfer. The primary tube fluting may also be helical (figure 1C) to promote turbulent flow of waste water, enhancing heat transfer. A thermally insulated jacket (figure 3A) can be provided around the heat exchanger.

Title: Formulation of a new diesel fuel suitable for diesel engines
Inventor: TULINO ROSARIO ROCCO
IPC: C10L1/23
Filed: 2014-01-29
Abstract: The fuel conceived for diesel engines is formulated using one part of standard diesel fuel and two groups of components with different characteristic rating. The first group is composed by reformulated chemicals (nitromethane, propanone, 2-hexyl nitrate, amyl nitrate, acetaldehyde, cyclohexane and diethyl carbonate), while the second group in made by a blend of vegetal oils properly balanced (camellia sasanqua oil, brassica carinata oil, jojoba oil and jatropha curcas). There are specific volume percentages of these ingredients. The fuel obtained with this formulation has a better thermodynamic performance and allows an appreciable reduction of carbon dioxide (CO2) and particulate matter (PT) output which are, respectively, approximately 50% and 60% lower.

Title: A method of and apparatus for controlling frame buffer operations
Inventor: BROWN DAVID
IPC: G06T15/00
Filed: 2014-06-03
Abstract: A data processing system comprises a host processor and a graphics processor that renders frames to be output and writes those frames to a frame buffer. When a new frame is to be generated and written to the frame buffer, the host processor determines, for a set of plural sub-regions, which may correspond to rendering tiles, that the frame has been divided into, which of those sub-regions could have changed from the frame previously used for the frame buffer 30 and generates information indicating which sub-regions should be rendered to generate the new frame on the basis of the determination 31. The information indicating which sub-regions should be rendered to generate the frame is provided to the graphics processor 32 and the graphics processor uses the provided sub-region information to render only the indicated sub-regions 33. The determination of which sub-regions could have changed may be made from a list of dirty regions provided by the processor or by comparing signatures representative of the content of the regions.

Title: Low power bidirectional bus
Inventor: WILLEM ZWART
IPC: H04L5/14
Filed: 2015-05-11
Abstract: A master module 10 and a slave module 40 are connected by a two wire bus 50. The first wire 52 carries a clock signal, which is driven by the master module. The slave module transmits a first bit pattern to the master module on the second wire 54. Each bit of the pattern is transmitted on the first half of successive clock cycles. The master module transmits a second bit pattern to the slave module on the same wire. Each bit of the pattern is transmitted on the second half of successive clock cycles. In order to transmit information from one module to the other, the transmitting module changes the pattern it is transmitting. The receiving module may then alter its pattern to acknowledge the information. The modules may transmit the same bit pattern as one another.

Title: Emulating transparent file processing
Inventor: Gregory Hayrapetian
IPC: G06F17/30
Filed: 2016-03-31
Abstract: Transparent file processing is supported particularly in Unix-like operating systems by emulating the desired file processing. Recipes are provided, for example, for local folders in user space, for whole devices (e.g., flash drives or network drives), and for folders synchronized to cloud data. By detecting the path type 204 for a file operation and selecting and applying the appropriate recipe 206, file processing 208 can be performed in a manner transparent to the user. The recipes include overmounting when the type includes an existing folder, remounting when the type includes a physical device and creating a new label when the type includes a synchronised folder. When a file is moved to or from the path by the file operation the file is preferably encrypted/decrypted as appropriate or compressed/decompressed as appropriate.

Title: Heat-pump heating apparatus
Inventor: KENG SENG CHUA
IPC: F25B30/02
Filed: 2014-08-28
Abstract: A heat-pump heating apparatus (1) for heating fluids comprising a plurality of fluid flow loops (110 to n10) superimposed onto a system flow circuit (10) between a system inlet (101) and a system outlet (102). The fluid flowing through the system flow circuit (10) is characterised by a relatively lower flow rate and a high temperature increment between the system outlet (102) and the system inlet (101) while the fluid flowing through each fluid flow loop (110 to n10) is characterised by relatively higher independent flow rates and lower temperature increments between respective loop outlet (114 to n14) and loop inlet (113 to n13). Colder fluid entering each loop inlet (113 to n13) is raised to a higher temperature by mixing with hotter fluid from a feedback fluid line (112 to n12), then, circulates through the condenser (132 to n32) to further gain temperature; and then, partially flows out of loop outlet (114 to n14) with the remaining returning via the feedback fluid line (112 to n12) to mix with and raise the temperature of colder fluid entering the fluid flow loop (110 to n10) from the respective loop inlet (113 to n13).

Title: Method and apparatus for resource balancing in an automation and alarm architecture
Inventor: ANDREI BUCSA
IPC: G06F9/50
Filed: 2015-10-02
Abstract: A method and system architecture for automation and alarm systems is provided. According to exemplary embodiments, relatively simple processing tasks are performed at the sensor level, with more complex processing being shifted to the gateway entity or a networked processing device. The gateway entity dynamically allocates processing resources for sensors. If a sensor detects than an event is occurring, or predicts that an event is about to occur, the sensor submits a resources allocation request and a power balancer running on the gateway entity processes the request. In response to the resources allocation request, the gateway entity allocates some processing resources to the requesting sensor and the data is processed in real-time or near-real-time by the gateway entity.
