Abstract: This invention provides an object locator to locate a variety of target objects. A selective directional transceiver is used to determine the relative direction of the target object, even in a multiple-story building, from a hand held component of the object locator. And moving the hand held component toward the target object according to the relative direction shall allow the user to quickly locate the target object. The hand held component may keep a list of identifications of multiple target objects in the memory and locate them one by one. A voice recognition unit and a key stroke recognition unit in the hand held component shall allow the user of the object locator to easily locate the object by voice and/or key stroke. To share the hardware, software, memory and the display unit of an existing device like cellular phone hand set, personal digital assistant, or car alarm remote, the object locator may be (embedded) accommodated in it, and expand its additional application.

Abstract: This invention provides a waste issue alarm device to detect and indicate the weight increment of new urine issue or feces issue in the diaper, and transmit a waste issue alarm. The number of the urine or feces issue is counted separately. The waste issue alarm will indicate the count of the urine issue and the feces issue and their weights. An adjustable belt unit with hanger is used to hold the waste issue alarm device and hang it outside the diaper. A remote alarm may also be used. It may also monitor the urine issue and the feces issue of multiple diapers. An emergency alarm may be activated when the carried component of the device is submerged in the water.
