Abstract: An e-commerce voice response determination system is provided and generally includes a server and a customer computing device. The server may determine, based on a user query, a plurality of product descriptions. The server may determine a similarity value between the user query and each of the product descriptions based on the similarity between each word of the user query and each word of the product descriptions. The server may determine the product description with the most similarity to the user query, and provide a response to the customer computing device based on that product description. In some embodiments, the server may determine whether the user query matches a predefined query. If the user query matches the predefined query, the server provides a response to the customer computing device based on a predefined response to the predefined query.

Abstract: A micromobility transit vehicle may include a wheel, an electric motor associated with the wheel, and a motor controller configured to control a motive force provided by the electric motor to the wheel. The motor controller may include a printed circuit board (PCB), one or more MOSFETs attached to the PCB, and a respective aperture defined through the PCB below each MOSFET. The motor controller may include a thermal assembly associated with each MOSFET and capable of dissipating heat from the MOSFETs to a heat sink. Each thermal assembly may include a heat transfer plug positioned at least partially within an associated aperture of the PCBA to contact an associated MOSFET, and a thermal interface material positioned between the heat transfer plug and the heat sink and capable of dissipating heat from the heat transfer plug to the heat sink.

Abstract: Methods, systems, and products protect personally identifiable information. Many websites acquire the personally identifiable information without a user's knowledge or permission. Here, though, the user may control what personally identifiable information is shared with any website. For example, the personally identifiable information may be read from a header of a packet and compared to a requirement associated with a domain name.

Abstract: Non-standard, resin-infused fiber bundle includes localized regions of fibers having a sub-nominal amount of polymer resin positioned along its length. These regions function as “bending regions,” where the non-standard resin-infused fiber bundle can be readily deformed by virtue of the reduced amount of resin. The bending regions segregate the non-standard resin-infused fiber bundle into what is, effectively, discrete (smaller) segments of (standard) resin-infused fiber bundle. The ability to easily manipulate the non-standard, resin-infused fiber bundle via the bending regions is useful for creating fiber-bundle-based preforms, and preform charges (assemblages of fiber-bundle-based preforms).
