摘要： An electronic key or other missing object locator device is responsive to the impulse characteristics of received sounds to distinguish expected impulse-like triggering sounds such as humanly produced hand claps from other impulse-like sounds such as speech or music or non-impulse-like sounds. Errors may be counted whenever the received sounds do not correspond to the expected characteristics of the expected impulse-like triggering sounds. Whenever the expected number of triggering sounds having the expected impulse characteristics have been discriminated and detected, an audible alert is sounded, provided that the errors are not too many. The device of the invention is thereby able to distinguish expected hand claps (or other humanly produced sounds) from non-intended music, speech or other impulse-like or non-impulse-like triggering sounds, rendering it operable even in noisy environments. False alarms from mechanical wave energy are prevented. The user may clap his or her hands in a free manner, and almost any “natural” clap succession, whether or not evenly spaced, and whether or not comparatively-fast or comparatively-slow, will result in the audible alert.
摘要翻译：电子钥匙或其他缺失的物体定位装置响应接收到的声音的脉冲特性，以将预期的类似于脉冲的触发声音（例如人为产生的手拍）与其他类似脉冲的声音（例如语音或音乐或非脉冲式声音）区分开来。每当接收到的声音不符合预期的类似触发的触发声音的预期特性时，可能会对错误进行计数。无论何时已经鉴别和检测到具有期望的脉冲特性的预期触发声音数量，只要错误不是太多，则发出可听见的警报。因此，本发明的装置能够将预期的手拍（或其他人为产生的声音）与非预期的音乐，语音或其他脉冲状或非脉冲式触发声音区分开，即使在嘈杂的环境中也能使其可操作。防止来自机械波能量的虚假警报。用户可以自由地拍手，几乎任何“自然”拍子连续，无论均匀间隔，以及相对快速还是相对缓慢，都会导致听觉警报。

摘要： A multi-station RF thermometer and alarm system measures temperatures and/or percent relative humidity at remote locations by RF weather stations, and displays received temperature and/or other weather data telemetry on a multi-station base station that provides out-of-bounds alarm signal indications whenever temperatures are outside of user-selectable minimum and maximum values. Randomized transmission times in one embodiment and two-phase unique transmission schedules in another lessen the possibility of on-going collisions between two or more transmitters contending for the base station at the same time. Redundant data transmission lessens the possibility of environmental noise interference. The redundant data, transmitted at random times in one embodiment, includes a unique channel ID code, house-keeping data, the current temperature and/or time-to-next-transmission data, and in another embodiment, transmitted at uniquely prescheduled times of two-phase transmission schedules, includes station location ID and transmission schedule phase. The weather parameter sensing transmitters operate at a low duty cycle with low peak current consumption resulting in long battery life. The multi-station ase station may be AC- or battery-powered. Channel and station ID switches are provided on the remote temperature sensing transmitters and on the multi-station base station in one embodiment and a station ID number selection switch is provided in another transmitter embodiment.
