摘要： A high frequency power distributor/synthesizer includes a first terminal useful as an input or output terminal for high frequency power; second and third terminals useful as outputs or inputs for high frequency power; high frequency transmission lines connected between the first terminal and the second or third terminal; a balance resistor connected between the second and third terminals; and a coil connected between the second and third terminals in parallel to the balance resistor to improve isolation and return loss without substantial influence on insertion loss of the distributor/synthesizer.

摘要： A wheel-mounted tire pressure sensor employs a Bourdon tube which deforms in relation to tire pressure to drive a pivotal arm. Opposite ends of the arm support magnets which can close reed switches arrayed around the path of travel of the magnets. The reed switches are connected to passive resonators in such a way that for each of a number of regions of travel of the arm, a unique combination of resonators is activated. The resonators are connected to a wheel-mounted antenna which faces a stationary antenna. Frequency signal matching the frequencies of the resonator are sequentially broadcast by the stationary antenna to the resonators, which are excited to oscillate if activated by the corresponding switch or switches. The excited resonator broadcast their frequencies back to the stationary antenna and to a display unit which decodes the combination of resonator frequencies to display the corresponding tire pressure. An optional alarm unit includes a memory unit which holds maximum safe speed values for each of the detectable ranges of tire pressure. The sensed tire pressure is converted to the corresponding speed limit value which is then compared to the sensed vehicle speed. If actual vehicle speed exceeds the preset safe value, an alarm is generated.

摘要翻译： 轮式轮胎压力传感器采用布尔登管，其相对于轮胎压力变形以驱动枢转臂。 臂支撑磁体的相对端，其可以关闭围绕磁体行进路径排列的簧片开关。 舌簧开关连接到无源谐振器，使得对于臂的多个行进区域中的每一个，谐振器的唯一组合被激活。 谐振器连接到面向固定天线的车轮天线。 与谐振器的频率匹配的频率信号由固定天线顺序广播到谐振器，如果由相应的开关或开关激活，谐振器被激励振荡。 激励的谐振器将它们的频率广播回到固定天线以及解码谐振器频率的组合以显示相应的轮胎压力的显示单元。 可选的报警单元包括一个存储单元，该存储单元保持每个可检测的轮胎压力范围的最大安全速度值。 感测到的轮胎压力被转换成对应的速度限制值，然后将其与感测到的车辆速度进行比较。 如果实际车速超过预设的安全值，则会产生报警。
