20090322519 | Security and tracking system to prevent the unauthorized use or access to a device having hydraulic components - A security and tracking system to prevent the unauthorized use or access to machinery having hydraulic components whereby the system has a rerouting device housed in a tamperproof casing. The rerouting device might have a selective re-directional valve that can be remotely activated and monitored using wireless signal technology to direct hydraulic fluid to at least two hydraulic circuits, a control center that communicates via wireless signal technology to the rerouting device, a first hydraulic circuit that has a source of fluid, a fluid pumping means, the rerouting device, and a power take off device (PTO) and a second hydraulic circuit that has the source of fluid, the fluid pumping means, and the rerouting device. In operation the rerouting device selectively routs hydraulic fluid about the hydraulic circuit that includes the PTO, thereby rendering the hydraulic equipment functionally operable until the hydraulic fluid is rerouted to the second hydraulic circuit. | 12-31-2009 |
20100033323 | RADIO FREQUENCY IDENTIFICATION (RFID) SURVEILLANCE TAG - An enhanced method and apparatus are provided for tracking and managing a plurality of packagings, particularly packagings containing radioactive and fissile materials. A radio frequency identification (RFID) surveillance tag is provided with an associated packaging. The RFID surveillance tag includes a tag body and a back plate including predefined mounting features for mounting the surveillance tag to the associated packaging. The RFID surveillance tag includes a battery power supply. The RFID surveillance tag includes a plurality of sensors monitoring the associated packaging including a seal sensor. The seal sensor includes a force sensitive material providing a resistivity change responsive to change in a seal integrity change of the associated packaging. The resistivity change causes a seal integrity tag alarm. A tag memory stores data responsive to tag alarms generated by each of the plurality of sensors monitoring the associated packaging. | 02-11-2010 |
20110012731 | Wireless Tracking and Monitoring Electronic Seal - An electronic security seal (e-Seal) is disclosed. The e-Seal monitors security of shipments including intermodal containers, reports tampers in real-time, monitors environmental status of goods and reports exceptions in real-time, and reports the location of the shipment with high frequency. The security monitoring complies with the ISO 17712 standard, adding electronic real-time reporting of tamper time and location and LED tamper indication. The e-Seal can be manufactured and operated at low cost due to diagnostic and logistic features. The e-Seal supports low cost upgrades due to a modular architecture allowing a plug-in update of separate functions. The e-Seal allows flexible usage across supply chain tradelanes, due to highly programmable operation including over-the-air remote programming via wireless communications. The e-Seal provides low power operation to save battery usage and lower costs. | 01-20-2011 |
20110267190 | Anti-Tampering Detection Using Target Circuit RF Signature - An anti-tampering device and method to inhibit or prevent unauthorized probing of an electronic circuit. Propriety target circuitry transmits a distinct signature in the form of an RF signal which is received by the RF anti-tampering detection circuitry. The transmitted RF signature is monitored by the RF anti-tampering detection circuitry for user-defined changes. In the event an unauthorized attempt is made to probe the target system electronics, the mass of the probe alters the RF transmission characteristics of the RF transmission media, changing the RF signature. The altered RF signature is received by the receiving antenna and RF receiver and is processed by signal processing electronics. The change in the RF signature indicates a tamper event and a predefined anti-tamper event is generated. | 11-03-2011 |
20120062380 | "INVISI WALL" ANTI-THEFT SYSTEM - A system which monitors a display of products includes a motion detection unit. The motion detection unit is configured to receive an electromagnetic signal from a sensor concerning a portion of a plane disposed between at least one product held in a display and an individual. Further, the motion detection unit determines whether the portion of the plane is breached based on temporal deviations in the electromagnetic signal and, in response to determining a breach, generates a notification of the breach. | 03-15-2012 |
20120194339 | SYSTEMS AND METHODS FOR DETECTION OF DEVICE DISPLACEMENT AND TAMPERING - A method for determining the displacement of or the tampering with a device is provided. The method includes determining an effective displacement in an X direction of a device, determining an effective displacement in a Y direction of the device, and determining an effective displacement in a Z direction of the device. The method also include determining if any one of the effective displacement in the X direction, the effective displacement in the Y direction, or the effective displacement in the Z direction is greater than a predetermined threshold, and when at least one of the effective displacement in the X direction, the effective displacement in the Y direction, and the effective displacement in the Z direction is great then the predetermined threshold, determining that the device has been displaced. | 08-02-2012 |
20130127617 | APPARATUS AND METHOD FOR DETECTING UNAUTHORIZED REMOVAL OF ASSET TRACKING DEVICE - An asset tracking device includes a mounting bracket and a housing attached to the mounting bracket. The mounting bracket includes a magnetic portion, first apertures that receive first fasteners for attaching the mounting bracket to the asset, and second apertures that receive second fasteners. Third apertures in the housing, aligned with the second apertures in the mounting bracket, receive the second fasteners for attaching the housing to the mounting bracket. When the housing is attached to the mounting bracket, the housing makes the fasteners in the mounting bracket inaccessible so that the mounting bracket cannot be removed from the asset. When the housing is removed from the mounting bracket, a magnetic switch changes state and triggers a controller to generate a tamper alert with location information indicating the location of the tracking device. A wireless transmitter wirelessly transmits the tamper alert and location information to a central monitoring station. | 05-23-2013 |
20140354427 | WIRELESS SAFETY ALERT SIGNALING SYSTEM - An emergency alert system comprising one or more access-controlled wireless transmitters and a plurality of wireless wearable receivers that can be deployed locally to privately warn users of potential danger, by allowing authorized users to use the transmitters to send alert signals to the receivers. | 12-04-2014 |
