Company patents

Sensormatic Electronics, LLC

Sensormatic Electronics, LLC's patent strategy reveals a surprising shift away from its core "Alarm & Signaling Systems," which, despite making up 45.0% of its portfolio, has seen a significant decline of -64.7% so far in 2026. While many categories show a general decline in patenting activity, the company had a notable, albeit temporary, surge in "Locks & Keys" in 2025 with a 125.0% YoY growth, indicating a brief, focused effort in that area before a sharp drop of -77.8% so far in 2026.

A power control system arranged for use in a power-over-Ethernet system comprises a battery ( 38 ), a battery charging unit ( 40 ) connected to, and for charging, the battery ( 38 ) and a processor ( 34 ) arranged to monitor the charge level of the battery ( 38 ) and, in response, to direct current to, or away from, the battery ( 38 ). A power-over-Ethernet (PoE) system for delivering power to a load comprises a powered device ( 14 ) and an Ethernet power sourcing device ( 20 ) configured to supply DC power to the powered device ( 14 ). The powered device ( 14 ) has a battery ( 38 ), a battery charge unit ( 40 ), and a processor ( 34 ). The processor ( 34 ) is arranged to monitor the current requirement of the load ( 16 ), and to control the charging of the battery ( 38 ) and the supply of current from the battery ( 38 ) to the load ( 16 ) in response to said monitoring. A method of providing current to a load ( 16 ) in a power-over-Ethernet system ( 10 ) which includes a power sourcing device ( 20 ), a battery ( 38 ) and a processor ( 34 ), comprises the steps of monitoring the current requirement of and the current supplied to, the load ( 16 ); monitoring the charge level of the battery ( 38 ); monitoring the current supplied by the power sourcing device ( 20 ); and adjusting the current supplied to the load ( 16 ), the current supplied by the power sourcing device ( 20 ) and charge level of the battery ( 38 ) in response to said monitoring.

SYSTEM AND METHOD USING PROXIMITY DETECTION FOR REDUCING CART ALARMS AND INCREASING SENSITIVITY IN AN EAS SYSTEM WITH METAL SHIELDING DETECTION

Filed:2010-09-28Pub:2011-05-12
Applicant:Adam S. BERGMAN

A system for detecting electronic article surveillance (“EAS”) marker shielding includes an EAS subsystem, a metal detector, an object detector, a timer, a cart detection subsystem and a processor. The EAS subsystem is operable to detect an EAS marker in an interrogation zone. The metal detector is operable to detect a metal object in the interrogation zone. The object detector is operable to detect objects located proximate to an entry point of the EAS subsystem. The timer is programmed to start a countdown sequence upon receiving a signal generated by the object detector. The cart detection subsystem includes a sensor array. The cart detection subsystem is operable to differentiate between a wheeled device and a human passing through the interrogation zone based on an output of the sensor array. The processor is electrically coupled to the EAS subsystem, the metal detector, the object detector, the timer and the cart detection subsystem. The processor is programmed to receive a signal from the object detector and the timer to initiate gathering information outputted from the cart detection subsystem and information outputted from the metal detector to determine whether to generate an alarm signal based on the presence of EAS marker shielding.
