Abstract: Disclosed are various embodiments for an automated temperature logging and predictive alerting system for monitoring items that are being cooled or heated. In one embodiment, a predictive logging application may compare a predicted temperature curve of an item to a predefined slope to predict whether or not the item will meet a target threshold. The target threshold may be a target temperature or duration rule that can be aggregated discontinuously over a single day or multiple days. If the projected temperature curve is predicted to not meet the target threshold, the logging application may send alerts notifying a client of available corrective actions. In projecting the predicted slope, the predictive logging application may train machine learning models to analyze historical data associated with the item and the user.

Abstract: A safe that may be secured to a fixed object while incorporated in a larger bag is provided. Also provided is a kit including a safe that can be installed in an existing bag. In use, the bag and safe are secured together and both may be simultaneously locked to a fixed object by a securing mechanism such as a loop cable with a locking mechanism. The securing mechanism enters both the bag and the safe through apertures which may be reinforced. The securing mechanism may be detached from the safe by detaching removable fasteners designed to secure the mechanism within the safe. The interior of the bag may also comprise a housing or a mounting mechanism to secure the safe within the bag.

Abstract: The present invention relates to a filter element for the extraction or brewing of beverages. In particular, the filter element facilitates brewing through increased permeability of fluid from a brewed beverage from brewable particles, such fluid including liquid and gas, and the easing of gas build up in a brewing device herein by the removal of gases emitted from a beverage medium housed within a beverage cartridge during brewing. The filter element may be used within a rigid, semi-rigid or soft pod that is insertable within a beverage brewer. The invention particularly concerns the brewing of coffee and coffee products in a coffee brewing machine configured to receive pods holding coffee particles that are injected with water and caused to brew coffee therefrom.

Abstract: Disclosed is an enclosed needle bearing hinge mechanism having externally rotatable race surfaces, internal needle bearings, an internal pathway for introducing grease into the assembly for improved lubrication, reduced wear and a construction adapted to support large door or latch loads. The assembly comprises a housing having at least one needle bearing in contact with an outer rotating race, stationary or counter-rotating interior races, a central pin shaft and an internal pathway for lubrication to be communicated from a topmost grease fitting to the contact interface between the needle bearing and outer rotating race. One or plurality of needle bearing assemblies and counter-rotating outer races may be present within the assembly, each with an independent grease pathway branch. The pathway comprises a hollow internal conduit that allows lubricant to contact each needle bearing in the assembly, reducing friction and improving longevity of the hinge bearing assembly.

Abstract: There is disclosed a variety of arrangements for laying of rigid pipe from reeled storage and/or on-board welding fabrication. Thirteen independent aspects of the invention are identified. In one particular arrangement (FIGS. 3a-3b), a tilting lay tower (106) having two travelling clamps (210, 220) is provided centrally on a pipelay vessel with a radius control arch (140) pivotable to receive rigid pipe from either port or starboard lay paths. A vertical axis reel or carousel (104) is provided, within an arrangement of curved take-off arms (130, 134) and a large radius curved wall (128). By these means, pipe can be loaded onto the carousel either clockwise or anti-clockwise, and can be supplied to the lay tower via the port or starboard lay path. Continuous rigid product fabricated by a selection of welding lines (112, 114, 116) at the port side can be guided around the large radius wall either for reeling onto the carousel or for direct feeding to the lay tower.

Abstract: An array of photovoltaic (PV) module(s) is arranged in series and/or parallel electrical connection to deliver direct current electrical power to an electrolyzer to produce hydrogen. The electric power is delivered by the array at its maximum power point (Vmpp) to deliver Ioper at Voper for the electrolyzer. The arrangement of the PV modules in the array, or the arrangement of cells in the electrolyzer, is continually monitored and controlled by an automatic controller system to operate the PV and electrolyzer systems at or near their respective maximum efficiencies. A DC-DC converter may be used to adjust the Vmpp to the operating voltage of the electrolyzer.
