Abstract:
Un arreglo (21) de sensor que comprende una pluralidad de aparatos en donde cada aparato (1) dentro del arreglo comprende: una pluralidad de sensores (3); circuitería (5) de lectura configurada para leer información de cada uno de la pluralidad de sensores (3); en donde cada aparato (1) tiene información de identificación e información de calibración almacenada con la información de identificación de manera que la información de identificación permite recuperar la información de calibración y cada aparato (1) está configurado para acoplarse al menos a otro aparato (1) en el arreglo (21) de sensor; en donde cada aparato (1) está configurado para calibrarse antes de acoplarse al menos a un aparato (1) en el arreglo (21) de sensor y el arreglo (21) de sensor está configurado para calibrarse después de que la pluralidad de aparatos (1) se han acoplado.
Abstract:
An apparatus comprises a sensing unit having a plurality of laterally-spaced fluid sensitive elements 902 and at least one readout node 903 associated with the fluid-sensitive elements, wherein the fluid-sensitive elements are configured to exhibit a characteristic response to the presence of a fluid 906 in their respective localities, and wherein the at least one readout node is configured to receive signalling from the associated fluid-sensitive elements indicative of the characteristic response, and transmit signalling to a reader 904 to enable the presence and location of the fluid to be determined based on the signalling received from the fluid-sensitive elements. The fluid may be moisture, carbon dioxide or ammonia for example. The apparatus may form an array of sensors tailored to cover a specific area for wireless monitoring, where the sensors are based on impedance, resistance, or capacitance measurements.
Abstract:
An apparatus and method, the apparatus comprising: a plurality of sensors; readout circuitry configured to read information from each of the plurality of sensors; and wherein the apparatus has identifier information and calibration information stored with the identifier information and the apparatus is configured to be coupled to at least one other apparatus to form an array of apparatus.
Abstract:
A bus interface couples a master device and one or more slave devices. Upon detecting a condition on the bus, one or more of the slave devices may force an extension of the bus condition for a predetermined time period. The forced extension may comprise forcing a voltage level, causing other devices on the bus to change modes. A master on the bus may detect an out-of-variance bus condition and, in response, take action to change the bus state to a stable condition. The bus interface may include power contacts and a single-wire bus for communicating between a host device and one or more battery packs.
