Title: Communication between client device and server
Inventor: LAURI OLLINPOIKA PIIKIVI
IPC: H04L47/80
Filed: 2019-11-27
Abstract: The invention relates to constrained devices such as IoT sensors and reducing the communications load on them. The devices may use protocols such as Lightweight Machine to Machine (LwM2M), IPv6 over Low Power Wireless (6LoWPAN). The devices include multiple objects, object instances or resources (OOIR) (e.g. temperature and humidity sensors). Each object may have a data reporting policy 505,530 (e.g. timeout, threshold triggered, etc.). To reduce communications traffic at least one OOIR has a dependent policy 530 whereby it can only piggy back on the communication of an OOIR with an independent policy. The dependent policy can be combined with other policies 534, 536, 538, 540 (e.g. thresholds). The dependent policy may be a logging one whereby multiple data points with time stamps are transmitted 548, or may simply transmit the most up to date value (Fig. 5a).

Title: Brake mass parameter
Inventor: MICHAEL ROBERTSON
IPC: F16D66/00
Filed: 2020-03-30
Abstract: A method and apparatus to determine a mass parameter indicative of a mass of an aircraft brake assembly. The mass parameter is determined using an estimated amount of energy absorbed by the brake assembly Eabs in a given period of time and a corresponding estimated change in temperature ΔT of the brake assembly. The mass parameter may be the brake mass m multiplied by the specific heat capacity c and be calculated by dividing energy absorbed by the temperature change (e.g. using Eabs = m.c.ΔT). The energy absorbed may be calculated by integrating over time the product of the wheel speed and torque, or the product of wheel speed, applied brake pressure and a gain factor. The temperature estimate may depend on a time delay between the energy being absorbed and the temperature change and/or be based on cooling apparatus operational information. A trend of the mass parameter over time may be determined and used to predict a number of good future use cycles of the brake discs, e.g. by comparing with the measured change in length L due to brake wear to determine how much carbon-carbon brake mass has been lost due to thermal oxidation.
