A security tag can prohibit unauthorized usage of a device or product. The device may include an electronic nicotine delivery systems (“ENDS”) device, which may include aerosol delivery devices such as smoking articles that produce aerosol. The security tag can prevent usage until authorized. Attempts at usage without authorization can result in the device being unusable. The authorization may include identity confirmation or age verification.

A panel speaker includes: a first panel; a second panel; a vibration actuator configured to vibrate the first panel and the second panel; an adhesive layer configured to adhere one surface of the first panel to one surface of the second panel; and a coupling portion configured to couple other surface of the second panel with the vibration actuator, the adhesive layer includes a plurality of strip-shaped regions parallel to one direction in a plan view of the second panel, and the coupling portion is disposed at a region sandwiched between adjacent two of the plurality of strip-shaped regions in the plan view of the second panel.

A system for obtaining content for display to a user of a head-mountable display device, HMD, the system comprising one or more audio detection units operable to capture audio in the environment of the user, a motion prediction unit operable to predict motion of the HMD in dependence upon the captured audio, and a content obtaining unit operable to obtain content for display in dependence upon the predicted motion of the HMD.

A low-cost, multi-function adhesive wireless communications and transducer platform with a form factor that unobtrusively integrates one or more transducers and one or more wireless communication devices in an adhesive product system. In an aspect, the adhesive product system integrates transducer and wireless communication components within a flexible adhesive structure in a way that not only provides a cost-effective platform for interconnecting, optimizing, and protecting the constituent components but also maintains the flexibility needed to function as an adhesive product that can be deployed seamlessly and unobtrusively into various applications and workflows, including sensing, notification, security, and object tracking applications, and asset management workflows such as manufacturing, storage, shipping, delivery, and other logistics associated with moving products and other physical objects.

Systems, methods, and computer-readable media are disclosed for contactless power converter aging detection. An example method may include receiving, from a microphone, first acoustic data associated with a power converter. The example method may also include converting the first acoustic data into second acoustic data, wherein the first acoustic data is time domain data and the second acoustic data is frequency domain data. The example method may also include determining, by a machine learning model and based on the second acoustic data, a remaining useful life value associated with the power converter.
