  • Patent number: 10386425
    Abstract: A method of determining power fault information using a voltage regulator-down (VRD) device having a fault-pin output. The method may include receiving a fault indication from one of a plurality of fault detection devices, correlating the received fault indication with a timing signal having a predetermined time duration, applying a voltage change on the fault-pin output of the VRD device for the predetermined time duration corresponding to the timing signal, and applying the voltage change on the fault-pin output to a plurality of fuses. Based on the predetermined time duration associated with the applied voltage change, the plurality of fuses may be blown according to a binary pattern indicative of a fault type associated with the fault indication.

  • Patent number: 10244458
    Abstract: A method, computer system, and/or computer program product controls access to a wireless local area network (WLAN) access point in a retail establishment. A predetermined retail activity threshold is established for a retail establishment, where the retail establishment has a patron service area with a WLAN access point, and where a determination has been made that exceeding the predetermined retail activity threshold without increasing patron traffic out of the retail establishment will cause an excessive wait time for occupying the patron service area. In response to determining that the predetermined retail activity threshold is being exceeded, a secondary criterion is examined in order to determine if the mobile device should be disconnected from the WLAN access point, in order to motivate a user of the mobile device to leave the patron service area. If so, then the mobile device is disconnected from the WLAN access point.

  • Patent number: 9323321
    Abstract: A system, method, and/or computer program product comprises an input/output (I/O) bus and an intelligent current bank that couples a voltage source to the I/O bus. The intelligent current bank includes an ammeter that measures a real-time flow of current to the I/O bus. In response to the current to the I/O bus exceeding a predetermined level, an intelligent Pulse-Width Modulator (iPWM) within the intelligent current bank selectively decreases current to one or more electronic devices on the I/O bus by shortening a duty cycle of voltage being received by the iPWM from the voltage source.

The CPP further includes code for applying selected voltage levels to each LCE to display an image, and code for controlling an amount of backlight produced by backlighting elements in an addressable array while the image is displayed. Each backlighting element is aligned behind and logically associated with one LCE, and at least one backlighting element is controlled to compensate for a difference between the amount of light detected by the photosensor logically associated with at least one LCE and the other photosensors.
