Abstract: Described embodiments generally relate to a method for improving data accuracy of sleep pattern data. The method comprises receiving first data relating to at least one sleep pattern metric; receiving second data relating to the at least one sleep pattern metric, wherein the second data is data entered by a user; determining the difference between the first data and the second data to calculate a data infidelity value; and in response to the data infidelity value exceeding a predetermined threshold, prompting a user to enter third data relating to at least one metric.

Abstract: A caliper guide pin assembly has a tubular guide pin, a cap, a grease valve and a plurality of lubricating grooves; the plurality of lubricating grooves are radially distributed about the tubular guide pin; each of the plurality of lubricating grooves normally traverses into the tubular guide pin from an external surface of the tubular guide pin; each of the plurality of lubricating grooves traverses into the tubular guide pin from a front surface of the tubular guide pin; the cap is concentrically positioned with the tubular guide pin; the cap is positioned about the tubular guide pin, adjacent to the front surface of the tubular guide pin; the grease valve is positioned adjacent to the cap, opposite to the tubular guide pin; the grease valve is adjacently integrated into the cap; the grease valve is in fluid communication with each of the plurality of lubricating grooves.

Abstract: A caliper guide system for air disk brakes that provides a means of continuous maintenance, lubrication. The system includes a tubular guide pin, a cap, a grease valve, and a plurality of lubricating grooves. The tubular guide pin attaches a caliper head to a carrier of the air disk brakes to allow for relative motion. The lubricating grooves injects grease into the system and are radially distributed about the tubular guide pin. Each of the lubricating grooves normally and externally traverses into the tubular guide pin. The cap and grease valve seal off the tubular guide pin and allow for grease injection to the lubricating grooves. The cap is concentrically positioned about the tubular guide pin. The grease valve is adjacently integrated into the cap, opposite to the tubular guide pin. Resultantly, the grease valve is in fluid communication with each of the lubricating grooves.

Abstract: Disclosed is a method of estimating an arousal state of a person, the method comprising: providing one or more measurements of a physiological or behavioural variable relevant to the arousal state of the person; and updating a nonlinear physiologically based time-dependent model of arousal using the one or more measurements of the physiological or behavioural variable, thereby estimating an augmented state vector of the model, wherein the estimated augmented state vector of the model includes the arousal state of the person and one or more parameters of the model.

Abstract: A method of harvesting energy from a vibrational energy source having a varying energy characteristic. The method includes the step of varying a characteristic of a harvesting arrangement arranged to harvest the energy, the characteristic of the harvesting arrangement being varied in response to the varying energy characteristic of the vibrational energy source.

Abstract: A method of controlling total jet pressure from the head of a metallurgical lance for introducing gas into a volume of metal in a vessel. The lance head has at least one ejector, which has a nozzle located in a bore of the lance head and has an annular gas passage between at least one nozzle and the wall of the bore. The method proceeds by adjusting the annular gas velocity from a first Mach number to a second mach number to effect change of the total jet pressure.
