Abstract
abstract a wireless sensor reader is provided to interface with a wireless sensor. the wireless sensor reader transmits an excitation pulse to cause the wireless sensor to generate a ring signal. the wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. a voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. the voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined. the reader uses an ambient reading or other information to select a subset of the possible ring signal frequencies, and tunes or adjusts its circuits and algorithms to focus on that subset. tradução do resumo resumo patente de invenção: "leitor de sensor sem fio". a invenção refere-se a um leitor de sensor sem fio que está provido para interfacear com um sensor sem fio. o leitor de sensor sem fio transmite um pulso de excitação para fazer com que o sensor sem fio gere um sinal de toque. o leitor de sensor sem fio recebe e amplifica o sinal de toque e envia o sinal para um loop travado em fase. um oscilador controlado por voltagem no loop travado em fase trava sobre a frequência de sinal de toque e gera um sinal de contagem em uma frequência relativa à frequência de sinal de toque. o oscilador controlado por voltagem é colocado em um modo de retenção onde a voltagem de controle é mantida constante para permitir que a frequência de sinal de contagem seja determinada. o leitor utiliza uma leitura ambiente ou outras informações para selecionar um subconjunto de possíveis frequências de sinal de toque, e sintoniza ou ajusta os seus circuitos e algoritmos para focalizar sobre este subconjunto.
