摘要:
Near-Field UHF wireless coupling may be used to write data into a non-volatile memory in a device, thus allowing for changes to be made to the device after that product has been manufactured. Energy from the received wireless signal may be used to power sufficient circuitry in the device so that the programming does not require an on-board power source such as a battery. In many cases, the device may be programmed after it has been packaged for shipment/sale, without removing the device from the package. In some embodiments, a multi-segment antenna may be used to program multiple such devices at the same time by the same Near-Field UHF signal.

A single circuit may, in some embodiments, provide both static and dynamic power harvesting. The dynamic harvesting using switched transistors may be powered by the static harvesting circuit in one embodiment. That is, during a first phase, power may be generated in a static harvesting mode using diodes. That power generated in the first phase may be used in a second phase for dynamic power harvesting using transistors arranged in parallel to the diodes. The use of the transistors may, in some embodiments, result in the harvesting of more power. In some cases, the same capacitors may be used for both active and static harvesting.

Apparatus for resolving movement of a mass within a defined space utilizes at least one electrode proximate to the space to be observed. An AC signal is applied to the electrode, and the current measured from that electrode and also to any other electrodes included in the system, and which are effectively connected to the ground return of the AC-coupled electrode. A person (or object) to be sensed intercepts a part of the electric field extending beween the AC-coupled "sending" electrode and the other "receiving" electrodes, the amount of the field intercepted depending on the size and orientation of the sensed person, whether or not the person provides a grounding path, and the geometry of the distributed electrodes. Given the nonlinear spatial dependence of the field, multiple electrodes can reliably distinguish among a set of expected cases. The invention detects motion by taking sequential measurements at different times and utilizing the time variation in signal magnitudes as well as the absolute magnitudes themselves.

A radio frequency identification (RFID) tag may have a non-responsive mode, triggered by a command from an RFID reader, that temporarily prevents the RFID tag from responding to a query from any RFID reader for a period of time. In some embodiments this non-responsive mode may automatically end after a certain period of time without further action by the RFID reader. In other embodiments this non-responsive mode may end when directed to by another command addressed specifically to the RFID tag.
