Patent number: 11913597Abstract: A product-display system for displaying and securing a retail product. The system may include a retainer having a retainer bracket and a retainer body coupled to the retainer bracket. A retaining cable may be coupled to the retainer body at an opening in the retainer body. A fastener that may be unfastened to release the product from the retainer may only be accessed through the opening of the retainer body such that when the retaining cable is coupled to the opening, no fasteners of the retainer may be visible or accessible. The system may also include a display stem for holding the retainer and product. The display stem may include a recess for receiving at least a portion of the retainer body. The retaining cable may extend through the display stem and may simultaneously transmit power and data to a displayed product. The retainer may be returned to and held on top of the display stem using a retaining cable.Type: GrantFiled: December 1, 2021Date of Patent: February 27, 2024Assignee: Apple Inc.Inventors: Sheng Yang, Eric W.

Patent number: 11809552Abstract: Some embodiments described herein include a system that collects and learns reference side-channel normal activity, process it to reveal key features, compares subsequent collected data and processed data for anomalous behavior, and reports such behavior to a management center where this information is displayed and predefine actions can be executed when anomalous behavior is observed. In some instances, a physical side channel (e.g. and indirect measure of program execution such as power consumption or electromagnetic emissions and other physical signals) can be used to assess the execution status in a processor or digital circuit using an external monitor and detect, with extreme accuracy, when an unauthorized execution has managed to disrupt the normal operation of a target system (e.g., a computer system, etc.).Type: GrantFiled: April 5, 2021Date of Patent: November 7, 2023Assignee: Power Fingerprinting Inc.Inventors: Carlos R.

Patent number: 11144632Abstract: Some embodiments described herein include a method to validate supply chains for electronic devices using side-channel information in a signature analysis. The method includes sending, to a target device, a first signal associated with a set of codes to be executed by the target device, and then receiving first side-channel information associated with the target device in response to the target device executing the set of codes. The method also includes determining second side-channel information associated with a simulated device in response to the set of codes. The method further includes comparing a discriminatory feature of the first side-channel information with a discriminatory feature of the second side-channel information to determine a characteristic of the target device based on a pre-determined characteristic of the simulated device. Finally, the method includes sending, to a user interface, a second signal associated with the characteristic of the target device.Type: GrantFiled: November 21, 2019Date of Patent: October 12, 2021Assignee: Power Fingerprinting Inc.Inventors: Carlos R.

Patent number: 10859609Abstract: Some embodiments described herein include an apparatus having a processor communicatively coupled to a memory. The processor is configured to monitor, at a characteristic controller, a first characteristic of an electronic device. The processor is then configured to receive side-channel signature analysis of the electronic device from a signature analyzer. The processor is configured to determine if the first characteristic of the electronic device has changed or will change in a predefined period of time based on the side-channel signature analysis. The processor is then configured to adjust a second characteristic of the electronic device and/or filtering characteristics such that the side-channel signature analysis reflects predefined side-channel behavior.Type: GrantFiled: June 30, 2017Date of Patent: December 8, 2020Assignee: Power Fingerprinting Inc.Inventors: Carlos R.
