Title: Heating/cooling system for hot tub
Inventor: STUART MULCAHY
IPC: F24H1/00
Filed: 2017-09-01
Abstract: A spa bath comprising a tub 200 for water, a thermally insulative cabinet 202 for the tub and a heat pump installation 210 operable in a heating mode to heat the water in the tub. The heat pump installation is installed within the cabinet to use air within the cabinet as its source of heat. In heating mode, the temperature of the air within the cabinet rises above the ambient temperature by conduction from the heated water in the tub. As the cabinet is thermally insulative, the raised temperature of the air within the cabinet is largely maintained as long as the spa bath is in operation, and thus the within-cabinet heat pump installation has improved efficiency (or more precisely expressed, an improved coefficient of performance) compared with a heat pump having an external air source. The heat pump may be operable in a cooling mode to cool water in the tub. The heat pump installation may be contained within a housing having an inlet and an outlet for water and an inlet and an outlet for air.

Title: System for controlling power consumption on a distribution grid
Inventor: STEVE COX
IPC: H02J3/18
Filed: 2019-03-25
Abstract: A system is provided for controlling voltage supply to a portion of a distribution grid, the portion of the grid including a plurality of power-consuming units 22. The system has access to a data set of previously measured power consumption associated with properties of voltage, current, frequency or load in the portion of the grid, or a combination of these. The system includes a measurement device to measure the properties in the portion of the grid, and a processing device to determine from the previously measured values of the properties in the data set a most likely effect on the power consumption of power consuming units 22 of altering the value of the properties from a first value to a second value. A storage device stores rules associating a measured condition with a corrective action for the power- consuming units 22 to alter the value of the property(ies) from the first value to the second value, the corrective action including at least one of: turning power-consuming units 22 on or off; turning power-consuming units 22 off or on for a pre-determined duration of time and subsequently turning the unit back on or off, respectively; instructing the power-consuming units 22 to reduce or raise their power consumption. The system determines whether a measurement meets a measured condition of a stored rule and communicates instructions to the respective power-consuming units 22 to perform the corrective action associated with the triggered rule. This allows peak power demand to be managed by lowering grid voltage to reduce power consumption (conservation voltage reduction).

Title: Method of training a neural network to reflect emotional perception and related system and method for categorizing and finding associated content
Inventor: JOSEPH MICHAEL WILLIAM LYSKE
IPC: G06N3/08
Filed: 2019-04-03
Abstract: Training an artificial intelligence to reflect human subjective responses to stimuli, e.g. audio, music, images, videos or text, employs an artificial neural network (ANN) to identify similarity between the content of two files, e.g. music tracks. For audio files, measurable signal qualities, e.g. rhythm, tonality, timbre and texture, are extracted from both files to identify musical properties 404. The ANN outputs a property vector for each musical property 408, and the property vectors are assembled into a multi-dimensional vector for each file. The weights or bias values of the ANN are adjusted by backpropagation 422 based on the distance between the two multi-dimensional vectors 410 and any discrepancy between this distance and a quantified semantic dissimilarity distance between the two files in semantic space 412, such as textual description of the track or other semantic associations with events, feelings, themes or environments. Thus, the ANN is trained to align the distance between the files in property space to correspond to the distance between the files in semantic space. The ANN can then identify music files which are subjectively semantically similar to a target file based only on the target file’s objective musical properties.

Filed: 2017-11-27
Abstract: An approach is provided for securing communication between a server computer and a client computer. A first string is sent to the client in response to a request to permit an application being executed by the client computer to access a first function. A second string that includes a parameter of a second function is received.

Using the call, the server executes the second function. Based on a result of the execution of the second function and without requiring an implementation of native code, the server determines whether to (i) permit the application to access the first function or (ii) prevent the application from accessing the first function.
