  • Patent number: 12155665
    Abstract: Methods and system for monitoring and assessing employee moods are disclosed. A proposed enterprise employee monitoring system includes surveillance cameras, a facial recognition module, an emotional analyzer module, and an employee database. The surveillance cameras capture image data including employee individuals within the enterprise. The facial recognition module identifies the individuals in the image data, and the emotional analyzer module determines an emotional state of the individuals based upon the image data. The employee database stores employee information and the emotional state information from the emotional analyzer module, based upon the identification performed by the facial recognition module.

  • Patent number: 12136327
    Abstract: An EAS system first transmits a radio frequency identification (RFID) interrogation signal into an RFID interrogation zone of an EAS system. The system then first receives at least one RFID response signal from a first RFID tag of the system responding to the interrogation signal. The system second transmits a non-RFID RF signal into a second zone. The second zone and the RFID interrogation zone overlap to form a zone of interest. The system second receives, from the first RFID tag, an indication that the first RFID tag received the second transmission. The system determines, based on receiving both the RFID response signal from a first RFID tag and the indication that the first RFID tag received the second transmission, that the first RFID tag is in the zone of interest.

  • Patent number: 12118796
    Abstract: Aspects of the present disclosure relate generally to a vision system that detects persons exiting an environment, comprising detecting, by a processor using a plurality of image frames from at least one sensor, persons that exited the environment during a first period of time. The vision system further determines, by the processor, an exit count for the first period of time and retrieves, from a database, historical egress data comprising a detected historic exit count and a corrected historic exit count of the environment for a second period of time corresponding to the first period of time. The vision system calculates an error rate for the second period of time based on a ratio of the detected historic exit count and the corrected historic exit count, determines and stores a corrected exit count for the first period of time by adjusting the exit count using the error rate.

  • Patent number: 12080136
    Abstract: Deploying at each transition between separate areas of a facility a plurality of RFID reader antennas. Each antenna is deployed at a given transition covering a span of the given transition from a different perspective such that each point in the span is covered by at least two antennas. The antennas of a first transition between a first area and a second area of the separate areas detect, and in combination with an RFID system in communication with the antennas of the first transition, a tag known to have been in the first area. The RFID system identifies an item associated with the detected tag as moving to the second area. The antennas of a particular transition of the second area subsequently detect, in combination with the RFID system in communication therewith, the tag, and identifying the detected item as leaving the second area for an area across the particular transition.

  • Patent number: 11995917
    Abstract: Disclosed herein are apparatuses and methods for detecting a slip, trip or fall event in an environment and sending an alert of the event. An implementation may comprise detecting, in image frames captured by a camera, when an object enters a region of interest, tracking movements of the object, and determining that the object is in a fall-zone. The fall-zone may be specified by a set of line segments, each line segment being defined by points that lie in the region of interest. The implementation may further comprise, when the object is in the fall-zone, recording the position of the object, detecting a slip, trip or fall event when the object transitions from a first position above a predetermined height threshold to a second position below the predetermined height threshold, a pose of the object indicates that the object is lying down, or the object transitions from a vertical to horizontal pose, and sending the alert.
