    • Rooms in a building each have a heating, ventilating and air conditioning system (HVAC), a room control unit having a temperature controller, and various sensors. The control unit monitors the presence of persons in the room, determines the season, sets back the temperature in an empty room by a variable amount which the HVAC can restore in a given time, and restores the temperature to the previous user request when the user returns but to a standard temperature if the user has newly checked in. An outside hallway panel briefly displays, when interrogated by a maid, a person's presence. By monitoring maid requests, door status and maid activity, the unit indicates on a room map whether the room is being cleaned, clean, or ready to rent. By establishing the heat loss/gain (lg) factor of a room with the HVAC off and comparing it with the time to heat or cool the room, HVAC failures are determined. By comparing a room's lg factor with those of its neighbors, room environment failures are determined. A fire alarm is displayed immediately if more than one unit or more than one sensor reports fire; otherwise a fire alarm display is delayed briefly to reduce false alarms. Fire spreading is displayed on a screen room map showing in red rooms over a certain temperature. For fire, the hallway panels indicate those rooms where a person is present.
    • 建筑物中的房间均设有供暖,通风和空调系统(HVAC),带有温度控制器的房间控制单元和各种传感器。 控制单元监视房间中人员的存在,确定季节,将空房间中的温度设置为HVAC可以在给定时间内恢复的可变量,并且当用户恢复到先前的用户请求时恢复温度 如果用户新进入,返回到标准温度。外部走廊面板在被女佣询问时,会短暂显示一个人的存在。 通过监控女佣请求,门状态和女仆活动,该单位在房间地图上注明房间是否正在清洁,干净或准备出租。 通过建立HVAC关闭房间的热损失/增益(lg)因子,并将其与加热或冷却房间的时间进行比较,确定HVAC故障。 通过将房间的lg因子与其邻居的因子进行比较,确定房间环境故障。 如果多于一个单位或多个传感器报告火灾,则会立即显示火灾报警; 否则火灾报警显示会短暂延迟,以减少虚警。 火焰蔓延显示在显示在一定温度的红色房间的屏幕房间地图上。 对于火,走廊面板表示一个人在场的房间。

    • To detect an intrusion the apparatus projects one or, better, two beams of infrared rays in a direction selected by the user. A lens collects part of the radiation diffused back by the surface on which the beam impinges (whose distance must be in the range covered by the apparatus) and concentrates the collected radiation to form an image, almost pin point, of the "illuminated" surface. The position of said image depends on the distance of the surface impinged on by the beam. A photodetector provided with a slit placed in front is displaced until it detects the radiation forming the image. When the intruder intercepts the beam, the image of the "illuminated" surface, which is now on the intruder, will shift sideways enough to prevent the rays from passing through the slit and therefore from reaching the photodetector. The absence of the photodetector output signal indicates that an intrusion is occuring.The apparatus may be enabled to perform as fire detector, by means of a second photodetector fixed beside the former and before the diaphragm.
    • 为了检测入侵,该装置在用户选择的方向上投射一个或更好的两束红外线。 透镜收集由光束撞击的表面(其距离必须在设备所覆盖的范围内)的表面向后扩散的部分辐射,并集中收集的辐射,以形成“照明”表面的几乎针点 。 所述图像的位置取决于被光束照射的表面的距离。 具有放置在前面的狭缝的光电检测器被移位,直到其检测到形成图像的辐射。 当入侵者拦截光束时,现在在入侵者上的“照明”表面的图像将侧向偏移,以防止光线穿过狭缝,因此不能到达光电检测器。 没有光电检测器输出信号表示发生入侵。 该装置可以通过固定在前者周围和隔膜之前的第二光电探测器来执行作为火灾探测器。
