    摘要: A locator 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 tag unit can provide the indication to the handheld unit in response to the interrogation signal.

    摘要: A system can be for use with a number of reference tags disposed at respective reference locations in a coverage area. The reference tags can be configured to form a wireless mesh network. A system can include a first tag configured to communicate with the reference tags. The first tag can operate in a sleep mode and includes a motion sensor. The first tag is woken out of the sleep mode on a first periodic basis to communicate with the reference tags. The first tag is woken out of the sleep mode at a second periodic basis in response to motion signal from the motion sensor. The second periodic basis is more frequent than the first periodic basis. The system can also include a positioning system configured to receive data related to the communication between the first tag and the reference tags. The positioning system can be configured to process the data to determine a location of the first tag.

    摘要: The system comprises a plurality of reference tags affixed to reference locations in a coverage area and configured to form a wireless mesh network. The system also includes a call tag configured to communicate with the plurality of reference tags and to collect data regarding the communication with the plurality of reference tags. The call tag is configured to send a first signal in response to an event. A positioning system is coupled to the wireless mesh network and configured to receive the first signal and the data collected by the call tag. The positioning system is further configured to process the data collected by the call tag to determine the call tag location with respect to the plurality of reference tags. A portable electronic device is configured to communicate with the wireless mesh network and configured to receive call tag location from the positioning system.

    摘要: A capacitive sensor pad includes a foam plastic pad and heavy aluminum foil plates located to the opposite side thereof. The plates are adhesively bonded to the inner surfaces of an outer cover. The capacitor of the pad is connected in circuit with an oscillator and produces a frequency-related output. A ripple counter establishes a frequency-related output proportional to the capacitance. A microprocessor reads the counter output and a plurality of samples are averaged to establish a reference base and the true weight affect of the patient on the sensing pad. Other factors which might effect the signal are readily attended to by programmed compensation. Each subsequent sample is averaged and compared with the reference base. If within a permitted range, the latest and current signal is averaged with the reference base and establishes a new base, and continuously tracks changes in the sensing system. A selected change in a selected time delay system by requiring a series of alarm states or immediately if advance warning is desired, actuates an alert or alarm system, which requires positive resetting to terminate the alarm system. The system is positively reset to return to normal position monitoring. The system may be set to automatically reset the alarm system after an alarm condition is established and then removed by the continuous tracking of the patient movement.
