A power generation system for wheeled objects comprises a generator mechanically coupled to one or more of the object's wheels to convert wheel rotational energy into electrical energy. The power generation system may comprise an electrical storage device configured to store the electrical power produced by the generator. Power from the generator and/or the electrical storage device can be used to provide power to other electrical systems in or on the object. In certain embodiments, the electrical storage device comprises a bank of high-capacity capacitors connected in series. Some embodiments use a control circuit, for example, to regulate the charging and discharging of the capacitor bank and to provide suitable voltages for other systems. The power generation system may be disposed within an object's wheel, such as a wheel of a shopping cart.

Example embodiments of the present disclosure include a system comprising a computer-readable storage medium storing at least one program and a computer-implemented method for providing a recommendation based on a level of buying intent of an individual. Consistent with some embodiments, the method may include monitoring an amount of time an individual wears a particular item while in a fitting room of a retail store, and determining an interest level of the individual in purchasing the item based on the amount of time the individual wears the item. The method may further include generating and providing a recommendation for an additional based on the determined level of intent.

The present invention relates to radio-frequency identification (RFID) tags that produce a unique radar signature by passive reflection of an electromagnetic signal. In particular, provided herein are frequency-, phase-, and/or amplitude-shift encoded RFID tags, and methods of use and manufacture thereof.

Provided herein is a monitoring system and method for a bolting operation, during which a torque tool is coupled to a torque sensing and transmitting adapter disposed of with an RFID reader or a middle device to read the information in the RFID tag attached to each bolt following the preset bolting sequence. After receiving the information, a torque control device evaluates whether the bolts are valid and memorizes the bolting sequence, edits and stores in the memory. The torque control device continuously monitors whether the operator does follow the programmed bolting sequence and the bolting mode to fasten the bolt with target torque value and issues a warning if otherwise. Meanwhile, the torque control device writes the bolting information in the tag or stores the information in a peripheral server or in a cloud server via the Internet for later inquiry.

An aerosol delivery device includes a chamber for receiving an article including an aerosolizable material for delivery by the aerosol delivery device, a transmitter, a receiver spaced apart from the transmitter, and a processor. The processor is configured to: cause the transmitter to transmit a first signal to the receiver at least partially through an article in the chamber in use, so that the receiver receives a second signal, wherein the second signal is the first signal altered by interaction with a signal altering component of the article, and determine article data from the second signal. An article includes an aerosolizable material; and a signal altering component. The signal altering component is configured to alter a first signal transmitted at least partially through the article into a second signal indicative of article data.

An incontinence detection pad has an RFID tag in which an authentication code, such as an electronic product code (EPC), is stored. A reader in wireless communication with the RFID tag of the incontinence detection pad verifies that the incontinence detection pad is an authorized detection pad. Thus, unauthorized incontinence detection pads that do not have the proper authentication code are not able to be used in an incontinence detection system.

An absorbent article has one or more fluid filter layers to inhibit electrode traces from being exposed to low volumes of fluid to reduce the number of false positives that are indicated by an RFID tag of the incontinence detection pad. An antenna inlay has a sacrificial trace portion to permit testing for proper operation of an RFID chip electrically coupled to the antenna inlay. After testing, the sacrificial trace portion is severed. A fluid barrier layer blocks fluid from reaching portions of electrode traces that are located on a backsheet outside a periphery of an absorbent core of an incontinence detection pad. The power at which an antenna transmits to wirelessly energize a passive RFID tag of an incontinence detection pad is controlled to reduce the number of false positives indicated by the RFID tag.

A portable electronic device (100) having a touch screen (112) with a floating soft trigger icon (175) for enabling various functions of the electronic device (100), such as bar code reading, capturing RFID data, capturing video and images, calling applications, and/or placing phone calls. The floating trigger icon (175) is displayed on the touch screen (112) to enable easy identification and access of the trigger icon (175). The trigger icon (175) may be selected via application of any one of various unique control gestures (200, 210, 220, 230, 240, 250, 260) to configure the electronic device (100). Based on the selected mode or function of the device (100), the trigger icon (175) may alter its appearance to facilitate use of the device (100). The operation and functionality of the trigger icon (175) may be programmed to customize operation of the device (100).

In some implementations, a system may receive, from a motion sensor, an inactivity indication that indicates a period of inactivity within a physical environment. The system may store, in a data structure, identifiers of a plurality of RFID tags that a tag reader read during the period of inactivity. The system may receive, from the motion sensor, a motion notification that indicates a period of activity within the physical environment. The system may cause the tag reader to collect an identifier of an RFID tag in the physical environment during the period of activity. The system may determine, based on the identifier and the identifiers of the plurality of RFID tags, a movement status associated with the RFID tag during the period of activity and perform an action associated with the movement status of the RFID tag.

A method optimizes an object tracking system that uses receivers to receive beacon signals, or pings, from tracking tags that are attached to objects. An optimizer receives locations of the tracking tags and groups identifiers of the tracking tags into two or more sets. The first set identifies tracking tags that are attached to objects involved in a situation of interest. The optimizer determines a first receiver group based on the locations of tracking tags in the first set and the locations of the receivers. The optimizer determines a center of a smallest three-dimensional polygon bounding the locations of tracking tags in the first set. An antenna of each receiver in the first receiver group is then steered to point towards the center of the polygon while a number of receiver events per second generated by the receiver for tracking tags in the first set increases.
