  • Publication number: 20100114511
    Abstract: A circuit tracks the total amount of time that a host device has spent in its high power “activated” state (an optionally idle and hibernate states) and thereby can estimate the total power consumed by the tag. A remote device can query the state of a counter storing a value representing this time to accurately determine how much of the energy has been consumed by the host device and how much time is left and/or how many more operations can be performed before the host device's battery is exhausted.

  • Patent number: 7612652
    Abstract: A system and method for selectively activating a device based on an activate command. A circuit, in low power mode, listens for an activate command. The activate command includes a preamplifer centering sequence, an interrupt signal, and an activate code. The circuit receives a signal that may or may not be an activate command, self-biases the signal based on the preamplifer centering in the preamp/gain control, then determines whether the interrupt signal is of the proper length in the interrupt circuit. If the interrupt is not the proper length, the process stops. If it is the proper length, the command is recognized as an activate command, and a data slicer compares the activate code to a prestored value. If the activate code matches the prestored value, the device is powered up. If they do not match, the device is not initiated.

  • Patent number: 7604178
    Abstract: Systems and methods for activating devices such as RFID tags includes activating a device if an activate command matches a value stored on the device. The activate command can also define which mode of operation or state the device will initiation in, and whether an additional function or functions is to be performed upon activation. Activate commands can also be dynamically assigned to devices in order to increase overall efficiency.

  • Patent number: 7593822
    Abstract: Circuit and methods for tracking the total amount of time that a host device has spent in its high power “activated” state (and optionally idle and hibernate states) and thereby can estimate the total power consumed by the host device. A value representing this time may be send to a remote device to, for example, accurately determine how much of the energy has been consumed by the host device and how much time is left and/or how many operations can be performed before the host device's battery is exhausted.

  • Patent number: 7592970
    Abstract: A tiled display device is formed from display tiles having picture element (pixel) positions defined up to the edge of the tiles. Each tile includes a memory which stores display data, and pixel driving circuitry which controls the scanning and illumination of the pixels on the tile. The tiles are formed in two parts, an electronics section and a display section. Each of these parts includes connecting pads which cover several pixel positions. Each connecting pad makes an electrical connection to only one row electrode or column electrode. The connecting pads on the display section are electrically connected and physically joined to corresponding connecting pads on the electronics section to form a complete tile.
