Abstract

conjunto de amortecedor de mola a gás, sistema de suspensão, e, sensor de velocidade e deslocamento. a presente invenção se refere a sensores de amortecedores de mola a gás (126, 268, 376, 500) que incluem uma fonte de radar de ondas milimétricas (272, 382, 502) e uma superfície alvo (282, 284, 284', 388, 390) disposta em relação espaçada da fonte de radar (272, 382, 502). os sensores (126, 268, 376, 500) incluem também um receptor de radar de ondas milimétricas (274, 384, 512) operável para gerar um sinal mediante o recebimento das ondas de radar refletidas pela superfície alvo. a fonte de radar é operável para direcionar ondas de radar de comprimento milimétrico de frequência maior ou igual a 120 ghz e comprimento de onda de 2,5 mm ou menos em direção à superfície alvo. um processador (122, 528) é comunicativamente acoplado à fonte de radar e ao receptor de radar, e é operável para determinar um deslocamento e uma velocidade relativa com o uso de métodos de ondas de radar doppler pulsadas ou de onda de radar contínua modulada em frequência que se baseiam no tempo de voo e no deslocamento de fase de frequência das ondas de radar pulsadas ou contínuas. conjuntos de amortecedor de mola a gás (102, 200, 304) incluindo tais sensores, e sistemas de suspensão (100) incluindo um ou mais desses conjuntos de amortecedor de mola a gás também estão incluídos.
