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.

Abstract: A wireless circuit includes a housing, such as a hermetic housing, and at least one antenna coil wound about a coil axis within the housing. The coil axis may be substantially parallel to at least one wall of the housing, wherein the wall parallel to the coil axis is substantially thinner than other walls of the housing.

Abstract: Summarizing a system for obtaining a measurement from a remote location comprises a wireless sensor configured to change its resonant frequency in proportion to at least one sensed parameter; and a reader configured to define a band of resonant frequency values, to optimize itself for operation based on said band, to transmit an excitation pulse at only a fixed frequency to said wireless sensor, to receive a signal from said wireless sensor in response to said excitation pulse, and to sample and hold said received signal.

Abstract: Disclosed are a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to analyze the strength of a response signal transmitted from the wireless sensor in response to an excitation pulse generated by the reader device. In one embodiment, the reader device may be configured to engage be placed in a plurality of modes to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the wireless sensor to output a resonant signal. The reader device may receive the resonant signal from the wireless sensor and evaluate it against predetermined values. The evaluated signals may be used to assess the strength and the proximity of the reader device relative to the wireless sensor as it is implanted in a patient.
