    摘要: A method for testing wireless tags by a testing unit, comprising: transmitting a signal to energize a plurality of wireless tags within a testing area of the testing unit substantially simultaneously; waiting a prescribed amount of time sufficient to allow all of the wireless tags in the testing area an opportunity to respond with a transmitted message, each transmitted message including a unique identifier of the wireless tag; determining, based on information as to the identity of which wireless tags are in the testing area and receipt, if any, by the tester of the transmitted messages containing respective unique identifiers from the wireless tags in the testing area, which of the plurality of wireless tags are good and which of the plurality of wireless tags are bad.

    摘要: A temperature sensor is provided. The temperature sensor comprises: an inductor-capacitor (LC) oscillator configured; and a look-up table stored in a memory, wherein the look-up table contains a set of frequencies as a function of ambient temperature values, wherein when the LC oscillator is calibrated to a frequency from amongst the set of frequencies, the respective ambient temperature as stored in the look-up table is retrieved.

    摘要: A system and method for detecting a pick-up of an item and processing payment based on the detected pick-up are provided. The method includes receiving at least one data packet from at least one Internet of Things (IoT) tag, wherein each of the least IoT tag is attached to an item, extracting a frequency word from the at least one received data packet, wherein the frequency word is a measure of the at least one IoT tag, analyzing the frequency word to determine a pick-up event to be associated with a pick-up of the item attached to the at least one IoT tag, upon detecting the pick-up event, sending a notification including an identification of the at least one IoT tag, wherein the notification includes information associated with the picked-up item attached to the at least one IoT tag, prompting a user to purchase the picked-up item, and upon the user selecting to purchase the item, and associating a user's purchase account with the picked-up item; and commencing checkout of the item upon detecting the user exiting a location where the item is sold.

    摘要: An oscillator calibration circuit is presented. The oscillator calibration includes a first frequency locking circuit (FLC) coupled to a first oscillator, wherein the first FLC calibrates the frequency of the first oscillator using an over-the-air reference signal, wherein the first FLC calibrates the first oscillator prior to a data transmission session and remains free running during the data transmission session; and a second FLC coupled to a second oscillator, wherein the second FLC calibrates the frequency of the second oscillator using the over-the-air reference signal, wherein the second FLC calibrates the second oscillator immediately prior to a data transmission session and remains free running during the data transmission session.
