▎ 摘　　要

NOVELTY - The movable item has a unit (5) which comprises a fiber composite structure incorporating a sensor (33a-33n) for sensing a parameter and a circuitry (41). The fiber composite structure is formed of multiple structural layers or laminations which are formed from a sheet which is impregnated with a graphene-containing resin. An adaptive element (51a-51b) has multiple configurations and is configurable in response to a control input. The adaptive element is formed of a structurally-adaptive material which is configurable to have a defined material characteristic in response to the control input. The material characteristic of the structurally-adaptive material is defined by an electrical signal. The structurally-adaptive material is configurable to exhibit a defined stiffness, resilience and/or shock absorbance corresponding to the control input. USE - Movable item such as walking aid, wheelchair and vehicle such as bicycle, car e.g. performance car such as FI or race car, motorbike e.g. performance motorbike such race motorbike, train or aircraft such as airliner or fighter plane (all claimed). ADVANTAGE - The performance of the movable item is improved. DETAILED DESCRIPTION - The fiber composite structure incorporates a power source which is a capacitive battery source which stores charge and comprises conductive layers spaced by a dielectric layer in the fiber composite structure. An antenna is configured for wireless communication which comprises conductive layers spaced by the dielectric layer in the fiber composite structure. The sensor comprises a pressure gauge such as a strain gauge, for measuring pressure applied to the item, a motion sensor for measuring lateral movement of the item, an acceleration sensor for measuring acceleration of the item, a vibration sensor for measuring vibration of the item, a temperature sensor for measuring humidity, a yaw sensor for measuring yaw of the item, a pitch sensor for measuring pitch of the item, a roll sensor for measuring roll of the item, a wind sensor for measuring wind speed, an identification (ID) sensor e.g. Radio frequency identification (RFID) sensor for identifying the item. A unit which a fiber composite structure incorporating the antenna for wireless communication and circuitry. The sheet is a carbon fiber sheet in the form of a woven mat. The graphene resin is an epoxy resin. INDEPENDENT CLAIMS are included for the following: (1) a system for monitoring or controlling operation of a movable item and a processing unit (35) which receives information from the movable item, processes the received information and provides information relating to operation of the movable item. An information unit has a visual display for presenting information to the user, an audible source for presenting information to the user, and a pair of glasses for presenting information to the user. The processing unit is a processing center which is wirelessly connected to the movable item, by internet or a mobile telecommunications protocol, the processing unit is located in a fixed location remotely from the movable item, or the processing unit is implemented on a mobile telephone; and (2) a method for monitoring or controlling operation of a movable item.
