  • Patent number: 10199715
    Abstract: A system includes a central server; a reader in communication with the central server; and a set of equipment racks. Each equipment rack of the set of equipment racks defines a face. The each equipment rack includes an observer device and at least two antenna arrays. At least one of the at least two antennas is in communication with the observer device. The system further including a set of tags attached to assets disposed within the set of equipment racks. Each tag of the set of tags is to transmit a beacon signal including a tag identifier of the each tag. The at least one antenna is to receive the beacon signal. The observer device is to communicate the tag identifier and the characteristics of the beacon signal to the reader and central server. The central server determines a rack location based on the characteristics of the beacon signal.

  • Patent number: 10129611
    Abstract: A monitoring system can receive sensor measurements from a select sensor of a group of sensors. The sensor measurements are compared to group alert condition or an individual alert condition. Based on the comparison, an alert state can be identified and a user notified of the alert state. The system can automatically determine the individual alert condition, which can be uniquely associated with the select sensor and can be associated with a domain of time.

  • Publication number: 20110316674
    Abstract: A plurality of tags communicates a plurality of messages to a reader device. A message collector at the reader device collects at least a subset of the received messages, and provides the collected messages to a set of logical readers. The message collector and the logical readers filter the collected messages based on configuration information provided by an associated application, and provide tag event information to the application based on the filtered messages. The reader device can be configured based on customized configuration information, so that the tag event information provided to an application is customized for that application.

  • Patent number: 7696881
    Abstract: A series of radio frequency identification (RFID) systems are delineated. An RFID system comprises an RFID signpost having a transmitter for transmitting signals of a predefined type, and a receiver for receiving signals of the predefined type, wherein the transmitter for transmitting signals of the predefined type cannot transmit until a determination is made that the predefined type of signal is not present at the receiver. Another RFID system comprises an RFID signpost including a transmitter having a continuous power dissipation rating, and a processor for controlling the transmitter such that peak pulse power of a transmission from the transmitter multiplied by its duty cycle does not exceed the continuous power dissipation rating for the transmitter.
