Abstract: Absorbent articles incorporating a wetness sensor for indicating the presence of a body fluid are disclosed. In particular, the absorbent articles include at least two conductive elements that form an open circuit within the article. Each conductive element is connected to a conductive pad member that has sufficient surface area in order to facilitate connection to a signaling device. In accordance with the present disclosure, various attachment mechanisms are disclosed for attaching the pad members to a signaling device. In particular, although the absorbent articles are disposable, the signaling device is intended to be used with multiple absorbent articles. Therefore, a simple and efficient method of connecting the signaling device to the pad members provides various advantages. In one particular embodiment, for instance, the pad members comprise a conductive loop-type material that is attached to a corresponding conductive hook-type material on the signaling device.

Abstract: A flexible radio frequency identification label and a method for fabricating the same are proposed. A first flexible protection layer is attached to a second flexible protection layer to form a closed space for receiving a radio frequency identification circuit. By such arrangement, a good flexibility can be provided by the flexible protection layers, and the closed space also enables the radio frequency identification circuit to be protected and isolated from the moisture in the outside environment, such that the circuit can be prevented from being oxidized and the service life of the product can be extended.

Abstract: A light emitting diode (LED) signaling apparatus for navigational aids is provided. The signaling apparatus comprises a plurality of high intensity LEDs with their output beams individually controlled by high precision optical beam transformers. The transformed LED beams are mixed in a predetermined manner by controlling the relative position, angular orientation, and other parameters of the LEDs to produce a desired illumination pattern.

Abstract: A locator/wander management system includes a handheld unit for providing an interrogation signal. The handheld unit can be a handheld computer or PDA including an RF module. The interrogation signal is received by an RF tag. The RF tag can include a power source and a memory. The memory can store an indication of the date of installation of the battery. The RF tag can provide the indication to the handheld unit in response to the interrogation signal. The RF tag can also provide signals for a wander management system.

Abstract: An apparatus and method wherein a single sensor assembly will alarm both windows of a double hung window. The single sensor assembly provides a small magnet installed in the upper window sash and a sensor block installed on the lower window sash, said sensor block having a magnet contained in an internal raceway. The single sensor assembly is used in conjunction with a standard magnetic alarm system. The upper window sash magnet repels the sensor block magnet from one end of the sensor block diagonally upward within the sensor block raceway to an opposite end.

Abstract: An electronic diagnostic device for testing electronic monitoring tags for devices such as replaceable modules for a printing apparatus includes a tag reader with a reader wireless communication element. The tag reader is adapted to read tag diagnostic information from an electronic monitoring tag. The electronic diagnostic device further includes a data processor in communication with the tag reader. The data processor is adapted to determine from the tag diagnostic data whether the electronic monitoring tag is operating within predetermined parameters, to identify one of a predetermined set of error categories if the electronic monitoring tag is operating outside the predetermined parameters, and to generate error category information. The electronic diagnostic device further includes a results communication element adapted to communicate the error category information generated by the data processor. The diagnostic device may also communicate correction information to the electronic monitoring tag.

Abstract: An object tracking system includes a plurality of tags. Each tag includes a mechanism for transmitting a triangulation signal and a position signal that is indicative of a change of position of the respective tag in a time period since a respective reset event. A plurality of triangulation stations receive the triangulation signals from the tags. At least one antenna receives the position signals from the tags. A computer is coupled to the triangulation stations and to the antenna. The computer is programmed to switch between (a) a first tag location algorithm to determine a current location of one of the tags using a differential time of arrival procedure based on the triangulation signal, and (b) a second tag location algorithm to determine a current location of the tag based on the position signal transmitted by the tag and a previous known location of the tag.

Abstract: An automobile diagnostic system monitors in real-time sub-system components. The system has a plurality of acoustic and video sensors in combination for audibly detecting and visually monitoring critical noise levels and/or vibrations in sub-systems such as brakes, shocks, universal joints, exhaust and transmission systems, etc. Each combination sensor is attached a particular sub-system component for monitoring. The data is recorded on a (VCR) system for visual identification and the recording transmitted to a television and Video Cassette. A control panel has a series of Light Emitting Diodes (LEDs) and audible alarms as respective visual and audible alert indicators of tuned frequencies for a particular sub-system component.
