A monitoring system includes a doorbell unit that includes a camera and a display and that is configured to receive a request to access the property. The monitoring system includes a monitor control unit that is configured to determine an authentication protocol for determining whether to grant the visitor access to the property. The monitor control unit generates a first image and transmits authentication data to a computing device. The monitor control unit provides the first image and instructions to output the first image on the display of the doorbell unit. The monitor control unit receives a second image captured by the camera of the doorbell unit. The monitor control unit determines whether the second image includes a representation of data that is based on processing the first image in combination with the authentication data. The monitor control unit grants or denies the visitor access to the property.

Point-to-point visual communications in a security monitoring system

Identification systems and methods for utilizing light signals with wavelengths approximately above or below human sensitive light spectrum are disclosed comprising a special mark, wherein the special mark emits or absorbs light signals in light spectrums approximately below or above the visible light spectrum, a server comprising a processing unit, and a storage area, wherein the special mark is capable of being detected by the photographic instrument, and wherein a digital file is saved in the storage area, and wherein the special mark carries information which identifies the digital file saved in the storage area.

System utilizing light signals with wavelengths approximately beyond human sensitive light spectrum

A method of operating a radio frequency identification (RFID) system is provided. The method interrogates RFID tags with an RFID reader and provides at least some of the collected tag data to a mobile device that is unable to communicate with RFID tags using the over-the-air interface. In some situations, the RFID system obtains the current location of the mobile device and determines the location of a target tag relative to the current location of the mobile device. Locating the target tag in this manner involves the interrogation of a reference tag located at the mobile device, along with the target tag, using one RFID reader. The position of the target tag relative to the reference tag is calculated in response to the tag response signals obtained from the target and reference tags. Moreover, location of the target tag can be independently determined relative to the location of a mobile reader, by using a reference tag attached to a fixed reader or to the mobile reader.

Radio frequency identification system and related operating methods

A method of transmitting radiofrequency identification (RFID) interrogation signals is disclosed. The method comprises detecting a first movement of a user in a first direction, determining a command from the first movement, and transmitting a RFID interrogation signal in response to the command.

Methods and systems for integrated consumer experience and social networking are disclosed comprising the function of presenting a communication function to facilitate communication among multiple users wherein different modes of communication are achieved through a unified process utilizing a context information. The methods and systems further comprise the functions of causing two images to be displayed wherein the two images overlap with each other, and presenting a logic to determine which one of the two images a gesture control signal is directed to. Additionally, the methods and systems can also comprise the functions of receiving a location information of a first device, receiving a location information of a second device, receiving a distance limitation from the first device, determining if the second device is within the distance limitation, and delivering a message from the first device to the second device if the second device is within the distance limitation.

Method and system for integrated consumer experience and social networking

An apparatus, system and techniques for determining a location of an RFID tag among a population of tags are disclosed. The system includes an RFID reader with at least one antenna port and a population of RFID tags. The population of tags can be homogenous or heterogeneous. The RFID reader varies its transmit power through one or more antenna ports resulting in a grouping of the RFID tags into clusters. In one embodiment, the reader utilizes multiple antennas to further define RFID tag clusters among the population. Each read tag is then uniquely associated with a defined cluster. Tag agents also can be provided among the population of tags facilitating definition of the clusters.
