摘要： 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.

摘要： 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.

摘要： In an active matrix electroluminescent display, a pixel containing a grounded conductive electric field shield between an EL cell and the switching electronics for the EL cell. In a method of fabricating the pixel, first, an EL cell switching circuit is formed, then an insulating layer is formed over the switching circuit and a conductive layer (the field shield) is formed over the insulating layer. A through hole is provided in the field shield such that an electrical connection can be made between the switching circuit and an EL cell. The EL cell is then conventionally formed on top of the shield layer. Consequently, the shield isolates the switching circuit from the EL cell and ensures that any electric fields produced in the EL cell do not interfere with the operation of the switching electronics. Furthermore, the switching circuitry for each cell contains two transistors; a low voltage MOS transistor and a high voltage MOS transistor. The low voltage transistor is controlled by signals on a data and a select line. When activated, the low voltage transistor activates the high voltage transistor by charging the gate of the high voltage transistor. This gate charge is stored between the gate electrode of the high voltage transistor and the electric field shield. Additionally, to improve the breakdown voltage of the high voltage transistor, a capacitive divider network is fabricated proximate the drift region of that transistor. As such, the network uniformly distributes an electric field over the drift region.

摘要： An active storage or memory cell includes first and second high input impedance inverters cross coupled to form a flip-flop. The output impedance of the second inverter is significantly lower than the output impedance of the first inverter. Input signals are applied at, and information is read out from, a single input-output point common to the output of the second inverter and the input of the first inverter via a gating means connected between said input-output point and an input-output line which is turned on more slowly than it is turned off.

摘要： A memory array includes row conductors which have to be charged to a first level prior to each read-out cycle. During a read-out cycle the row conductors may or may not be discharged to a second level depending on whether a "1" or a "0" is stored at selected bit locations. The memory array also includes "dummy" row conductors which are discharged to the second level each time the contents of the array are read out. Means are provided for charging the row conductors including the "dummy" row conductors to the first level prior to each read-out, for sensing the charge level on the "dummy" row conductors, and for terminating the charging cycle when the charge level on the "dummy" row conductors reaches the first level.
